The environmental improvement has happened to Baiyangdian Lake in Hebei Province since the plan to establish Xiong' an New Area was announced in April 2017.
The quality of water in the northern China's largest freshwater lake was below Grade V in the country's five-tier quality system for surface water in2017, according to the department of eco logy and environment in Xiong' an.
Thanks to a series of measures that have been taken, the quality of water in the lake reached Grade III in2021, and has stayed at that level in the past two years. Water with a quality of Grade III is good enough for most aquatic creatures to survive. The lake now has 276 species of wild birds, 70 more than in 2016, and 48 species of wild fish, 21 more than in 2016.
Feng Erwei, from Xidi Village near Baiyangdian, has been captaining a passenger boat on the lake for over 20 years. The 42-year-old is keenly aware of the environmental improvement in the water body.
He recalls when he was a young boy, people drank water directly from Baiyangdian. Diving into the lake with his friends, he said he could keep his eyes open underwater and see all the fish and shrimps swimming around.
The health of Baiyangdian began to sour in parts during the previous century as China quickly industrialized (工业化). In some parts of the lake, it became so polluted that even the locals would go out of their way to avoid it. "The terrible smell from the lake forced people who lived near it to keep their windows closed, and nobody swam in it any longer, " he said.
Now, as water quality improves, Feng says the Baiyangdian of his childhood is coming back.

You will be (吃惊的) to know that even satellites can be lost due to technical malfunctions, crashing (碰撞) with another object while in orbit, etc. All these can cause a satellite to lose its connection with the earth and become lost in space.
✔Lost satellite found!
In 1974, the USA launched a satellite (作为) part of the United States Air Foree's Space TestProgram. After the launch, the satellite failed to work (正常地) or properly, making it unusable for its planned purpose. Soon after, scientists lost track of it as it disappeared suddenly in space. However, they were able to move it to (另一) place in the 1990s, only to lose track of it again.
Now, after so many years, scientists have found the satellite again. We will have to wait and see if they can (设法) to bring it back to the earth or re start it.
✔What does this discovery highlight?
With the help of various equipment, scientists try to keep track of space debris(碎片). But tracking every object in orbit (是) difficult.
This discovery is a (胜利) for those tracking lost satellites and debris circling the earth.
However, as more satellites and spacecraft are being launched, space debris is (增加). So, in the future, it may be difficult to track all these things, which will become a problem.
Space debris can crash with spacecraft and can enter the earth's atmosphere, parts of which can reach the ground and cause damage. So, we (需要) to find ways to clean it up.

Yan Hongsen, an 11-year-old boy, has launched his second solid-fuel(固体燃料) rocket successfully!
Yan, called" rocket boy", is a fifth-grade student at a primary school in Shaoxing City, Zhejiang Province. He has been a 1 lover since he was just four years old, and even gave his classmates a lesson on astronomy(天文学) at an opening ceremony for the school.
During the summer break in 2022, Yan became an Internet sensation(轰动的人) after his father posted a video online in which the boy pointed out a rocket was 2 named in an education al video shown to visitors at a planetarium (天文馆) in Lhasa, Xizang Autonomous Region. The planetarium immediately corrected the several mistakes in the video and thanked Yan.
In the same year, Yan made his decision to 3 his own rocket. From August 2022 to June 2023, he spent ten 4 researching, studying and doing experiments, eventually creating his first rocket.
"That rocket only traveled 200 meters and then started to 5 , and did not open its parachute(降落伞) at the highest point, " Yan's father recalled. That day, Yan was 6 , yet unsatisfied. He researched where he went wrong. He made changes in his choices of materials, the engine and the flight control functions 7 he started to build the second rocket in October last year.

Chinese scientists have successfully developed a special national flag. The basalt(玄武岩) fiber flag was unfurled (展开) by the lander of theChang'e-6 lunar probe (月球探测器). The five-star red flag caught the eye of people around the world when it became the first national flag to fly on the far side of the moon.
The basalt fiber was developed by Wuhan Textile University and China Space Sanjiang Group Co. Xu Weilin, an academician at the Chinese Academy of Engineering, said his team overcame a number of hurdles over the past four years, including difficulty weaving the fibers and ensuring that the colors won't fade, in order to develop the high-quality" stone version" fabric national flag.
The flag that Chang'e-6 unfurled on the moon is the same size as the one planted during the Chang'e-5mission on the near side of the moon—30cm by 20cm, which is about the same size as a sheet of A4 paper. But the density (密度) of the basal t fibers used in theChang'e-6 flag is nearly twice that of the Chang'e-5 flag, which makes it reasonable to think that the basalt fiber flag is heavier. However, Xu's team developed the basalt fibers with a diameter about one-third that of human hair, so the Chang'e-6 flag weighs just 11. 3 grams, which is 0. 5gram lighter than the Chang'e-5 flag.
As a lightweight and flexible (柔韧的) protective material, basalt fibers will be used increasingly for spacesuits, spacecraft and lunar bases. Basalt fibers cost 25, 000 yuan per ton, which is much lower than quartz(石英) fibers and carbon fibers.
Typical firefighting suits and lifesaving rope are usually made of organic (有机的) materials, and they will burn at a high temperature of 550 ℃. However, the melting point of basal t fiber clothing is 1, 600℃, so it can be used for a short time at a high temperature of 1, 200℃, and for a long time at 800℃.
According to the scientists, firefighting suits, fire blankets and related products made from basalt fibers will be gradually produced in the years ahead.
(1)、The special national flag is made of ____A、basalt fibers B、carbon fibers C、quartz fibers D、organic materials(2)、The underlined word "hurdles "in the passage can be replaced by"____".A、programs B、experiences C、challenges D、experiments(3)、How does the writer develop Paragraph 3?A、By making a short report. B、By comparing the facts. C、By giving some examples. D、By following the order of time.(4)、What do the last three paragraphs mainly tell us?A、The basal t fiber has a promising market. B、The basal t fiber needs to be further studied. C、The basal t fiber can be available at a low price. D、The basalt fiber is a special protective material. -

Astronomers (天文学家) have discovered a "super-Earth", or a world larger than our planet, orbiting a star about 137 light years away. The planet, known as TOI-715b, orbits a red dwarf star(矮星) that is smaller and cooler than our sun, and a second planet could also be orbiting it.
Astronomers say the planet is around one and a half times as wide as our earth. The newly discovered planet is said to be close enough to its star to be in the habitable (宜居的) zone. The second planet may be slightly (稍微) larger than the earth and inside the same zone. The habitable zone is said to be the distance a planet has from a star at which the planet's temperature allows liquid water to exist on its surface.
Georgina Dransfield of the University of Birmingham, the United Kingdom, led the team behind the discovery. The team published a paper on their discovery in the Monthly Notices of the Royal Astronomical Society. Still, further research on the planets will be done.
Astronomers discovered the planet using NASA's Transiting Exoplanet (外行星) Survey Satellite (TESS). Since it launched in 2018, TESS has helped astronomers discover exoplanets or worlds outside our solar system. TESS detects and helps in studying asteroids, stars, and other distant galaxies.
With the earth's resources slowly getting extinguished(枯竭的), scientists have been working to discover a habitable home like our earth which humans can move to in the future. This will be done to avoid the extinction(灭绝) of the human race in case the earth becomes. uninhabitable.
However, we now don't have the required technology to move to different planets, and it will be many years before such technology can be developed. But you don't need to worry. The earth still has enough resources to last thousands of years. Still, we must try to save our planet so humans and the earth don't suffer.
(1)、What does the underlined word" it "in the passage refer to?A、The sun in the Milky Way. B、The red dwarf star in space. C、Our own earth circling the sun. D、A super-Earth about 137 light years away.(2)、What can we learn from the second paragraph?A、Two planets are both suitable for people to live on. B、The planet TOI-715b is just as large as our earth. C、Our earth is much smaller than the second planet. D、There is no water on the planet in the habitable zone.(3)、What's the fifth paragraph mainly about?A、How the earth's resources change slowly. B、Why scientists are searching for another earth. C、Whether the earth will become uninhabitable or not. D、What should be done to avoid the extinction of the human race.(4)、According to the last paragraph, the writer agrees that ____.A、moving to another planet is not possible yet B、we're suffering a lot from our planet now C、our resources on the earth won't be extinguished D、humans will move to different planets in the near future -

A chef planned to team up with a Florida-based space company to take fine-dining food to our upper atmosphere(大气) in late 2025.
Six guests are set to travel aboard Spaceship Neptune(海王星) to the stratosphere (平流层), where they will enjoy an immersive(沉浸式的) dining experience served up by Danish Michelin-starred chef Rasmus Munk.
Munk, 33, will travel with the guests and serve the meal himself, from a small kitchen. "We want to tell stories through the food, " Munk says. "I think that will make an even stronger impact when you're up there and looking down. "
Spaceship Neptune is more of a balloon than a rocket. The company says it will rise to around 30, 480 meters above sea level where the guests will dine while watching the sun rise over the earth.
Organizers say the trip, which costs $495, 000 per ticket, will last six hours. The flight won't technically reach" space" — Spaceship Neptune will rise to around30 kilometers, while the border between the earth's atmosphere and outer space is some 100 kilometers from the earth.
Munk's menu is expected to be very different from the meals eaten by past and present astronauts. The first man in space, Yuri Gagarin, squeezed(挤) beef and liver paste into his mouth from an aluminum tube. To save on weight, astronauts on the International Space Station usually dine on dishes packaged in containers that can be rehydrated (再水化). Though Munk is mysterious about his menu, he says he's planning to include glow-in-dark stars made from jellyfish protein(蛋白质). "We are also working on an edible (可食用的) piece of space junk from a satellite, " he said.
Last year Munk's restaurant was ranked the fifth best restaurant in the world. His space plan will attract more people to visit his restaurant in Copenhagen, the Danish capital.
(1)、What is Munk going to do in late2025?A、To build a small kitchen in space. B、To tell stories in Spaceship Neptune. C、To watch the sun rise over the earth every day. D、To provide food for the guests in the upper atmosphere.(2)、How much will six guests pay for their trip in all?A、$30, 480. B、$495, 000. C、$1, 485, 000. D、$2, 970, 000.(3)、What's the sixth paragraph mainly about?A、Munk's mysterious menu. B、Yuri Gagarin's eating habits. C、The space junk from a satellite. D、The astronauts' different meals.(4)、We can infer from the passage that Munk's space plan will ____.A、be finally accepted by more astronauts B、become a very successful one in2025 C、be a good advertisement for his restaurant D、have no influence on the space company -

At first look, Coober Pedy might seem like any other mining town in the central South Australia. But you di g a little deeper, you can find much more under the surface.
Once covered by the ocean 150 (million) years ago, the town of Coober Pedy, about 950 kilometers northwest of Adelaide, now holds the treasures the water left behind.
Beneath the red earth surface, colorful opals(欧泊) can be found in the rocks and there are so many opals that Coober Pedy has (name)"the opal capital of the world". Opals are formed from minerals(矿物质) left behind by the ocean that become solid over many years. They can (usual)be found inside cracks(裂缝) in the rocks, and once mined, they are often made into jewelry.
But there're more than just opals underneath surface of Coober Pedy. Because of the high outback temperatures, which are around 35℃ and higher in the summer, more than half of the town's population of 2, 000 (live) underground. Their homes called" dugouts(防空洞)" are carved out of the rocks. any windows, they keep a temperature of 19-25℃ all year round. And it isn't just homes that have been built in this way. The town also has underground (church) and even art galleries.
With Coober Pedy being around a day's drive from Adelaide, underground hotels have also been built for visitors. During their stay, tourists can take part in (look) for small opals on the ground surface, with areas of the town open to the public for doing so.

In the American state of California, there is a giant sequoia (红杉)I named General Sherman. It's the world's largest tree. Researchers1 climbed the tree to conduct the tree health inspection(检查).
The climbers had good news to report when they returned to the 2 . "The General Sherman tree is doing fine right now, " said Anthony Ambrose, who led the team of the researchers. They were looking for damage to the 2, 200-year-old tree, and 3 evidence of a growing threat (威胁) to the tree: bar k beetles(甲虫), which are native to California.
No one had ever climbed the 4 85-meter sequoia tree, which draws tourists from around the world to Sequoia National Park. It has survived for 5 years in California.
Hot and dry weather and wildfires have threatened sequoia trees in recent years. In 2020 and 2021, record-setting wildfires 6 as much as20 percent of the world's 75, 000 sequoias.
"But we certainly don't want to be caught by surprise 7 a new threat, which is why we're studying these beetles now, " said one researcher.
Researchers are growing more 8 about bar k beetles. The insects were not a serious threat in the 9 . They have lived alongside sequoias for thousands of years. But only recently have they been able to kill the trees. Scientists say they recently discovered about 40 sequoia trees that have died from beetle infestations(侵扰), mostly within the national parks.
Researchers believe drought and fire make the trees 10 and less able to survive attacks. The beetles are very small in size 11 large in number. Working together they can kill a tree within six months.
That is why park officials allowed Ambrose and his team to 12 General Sherman. They examined the branches and trunk, looking for the 13 holes that show beetle activity.
But it is not possible to climb every sequoia tree and 14 its highest part. So, scientists are considering other ways to check the trees, such as the use of drones(无人机). The 15 might be able to record and monitor beetle activity on a larger scale within the forests.

Scientists have found what they believe could be the deepest blue hole in the world
A team of researchers tried to measure the depth of the ocean hole known as Taam Ja' Blue Hole (TJBH), in Chetumal Bay off North America's Yucatán Peninsula.
They found the hole is at least 420 meters deep, but they failed to reach the bottom after the measuring equipment they were using became stuck. The measurements make TJBH at least146 meters deeper than the previous record holder, the Sansha Yongle BlueHole, or the Dragon Hole, in the South China Sea, which measures 302 meters to the bottom.
In a recent study published in the scientific journal, Frontiers in Marine Science, the researchers wrote that the bottom of the blue hole could be home to sea creatures that have never before been seen by humans. Blue holes are vertical (垂直的) marine caves that were carved over thousands of years by glacial (冰川的) run-off during the Ice Age, according to Discovery. com.
However, since these holes are filled with the gas hydrogen sulphide (硫化氢) and have very little oxygen in them, they can be dangerous for people to visit unless they have special diving equipment. The difficulty exploring these holes means not much research has been done on them.
While TJBH was first discovered in 2021, scientists only measured its depth down to 274 meters due to limitations in the echo-sounder technology, which used sound waves to measure speed.
During the latest expedition, the state-of-the-art device measures and sends water data to the surface in real time using a cable that goes down as far as 500 meters. But the cable stopped at 421 meters, possibly because it hit a ledge(岩架) or was affected by underwater currents, and the team wasn't able to hit the bottom of the hole. The scientists said they hoped to hit the bottom on their next excursion.
In the report, the researchers said they believed that the bottom might have a system of caves and tunnels that could possibly be home to undiscovered life forms.
(1)、How deep is the blue hole named TJBH?(2)、What is the blue hole?(3)、What dangerous gas can be found in blue holes?(4)、What could be at the bottom of TJBH according to the researchers?(5)、What do you think of the scientists' excursion to blue holes? -

An orangutan (红毛猩猩) named Rakus has surprised researchers. The orangutan, believed to be about 35 years old, lives in Gunung Leuser National Park in northern Sumatra, Indonesia. Scientists first noticed the orangutan's wound on June22, 2022. They believe it was most likely the result of a fight with another orangutan. Three days later, they observed Rakus chew up leaves of a medicinal plant used by people throughout Southeast Asia to treat pain and inflammation(炎症).
Since Sumatran orangutans rarely eat the plant, the scientists were intrigued and decided to observe and document Rakus' behavior. The orangutan spent the first13 minutes eating the plant. He then spent another seven minutes chewing the leaves and applied the plant juices to his injury. When flies began hovering around the cut, Rakus covered it with the leaves. Within five days, the wound had closed. By July 19, 2022, it was completely healed—— only a scar remained, according to a new study in Scientific Reports.
"This is the first time that we have observed a wild animal applying a medicinal plant directly to a wound, "said a biologist at the Max Planck Institute of Animal Behavior in Konstanz, Germany. Scientists have been observing orangutans in Indonesia's Gunung Leuser National Park since 1994, but they hadn't previously seen this behavior. It's possible Rakus learned the technique from other orangutans living outside the park and away from scientists' daily scrutiny (仔细观察). Rakus was born and lived as a young animal outside the study area.
Scientists have ever recorded other primates (灵长类) before. Bornean orangutans rubbed themselves with juices from a medicinal plant, possibly to reduce body pains or chase away parasites (寄生虫). Chimpanzees in many locations have been observed chewing on the shoots of bitter-tasting plants to soothe (缓解) their stomachs. Gorillas, chimpanzees and bonobo s swallow certain rough leaves whole to get rid of stomach parasites.
(1)、Researchers were surprised because Rakus could ____.A、treat his wound with a medicinal plant B、eat leaves to get rid of stomach parasites C、use bitter-tasting plants to soothe his stomach D、rub himself with plant juices to chase away flies(2)、What does the underlined word "intrigued" mean in the passage?A、Worried. B、Careful. C、Interested. D、Warm-hearted.(3)、We can infer from the passage that ____.A、Rakus is a very clever animal B、Rakus loves fighting very much C、Rakus studied medicine from humans D、Rakus lives in the National Park all the life(4)、What is the writer's purpose of writing the last paragraph?A、To advise us to protect primates in the wild. B、To stress the further study of primates is needed. C、To tell us other primates used plants to treat themselves. D、To show how scientists found other primates. -

Lizard (蜥蜴) van Gogh? Could it be a lizardin India with a talent for painting like Vincentvan Gogh, the famous Dutch artist? Haha, no! That is not the case here. No li zard has been found to have painting skills.
Scientists have discovered a new species of lizard whose back is so unique that it can remind everyone of van Gogh's classic painting The Starry Night.
A team of scientists were exploring the Western Ghats in southern India when they came across this unusual lizard. Half a world away and 133 years after Vincent vanGogh painted The Starry Night, the masterpiece came to Ishan Agarwal's mind when he found a small, colorful lizard among the rocks. He began to wonder what he was trying to do. Then, a glimpse (一瞥) of the blue-and-yellow li zard changed all that. So it wasn't until Agarwal got the reptile, whose body is about 2. 54 centimeters long, back to the lab and analyzed its DNA that he found it was genetically distinct(截然不同的).
"We have incredibly different kinds of animals in the area, but we know little about them, " Agarwal says of the Western Ghats, where new species are regularly discovered.
The new li zard has been named "Cnemaspis vangoghi", in honor of the Dutch painter. It is described in a recent study in the journal ZooKeys.
Nature is the best artist, effortlessly creating amazing natural images, from the snow-capped mountains to beautiful sunsets and green fields. We are all amazed by how beautiful nature is and how it can create such beautiful things, even tiny creatures like the recently discovered lizard.

Yes, we know sharks are fish too, but they aren't the only whoppers in the ocean. Here are four of the world's biggest fish species, not including predatory (食肉的) sharks, as ranked byScuba.com.
Whale shark(鲸鲨)—— So named for its extremely great size, the whale shark is usually about 12 meters long but can grow as large as 18 meters. Unlike predatory sharks such as the great white shark or tiger shark, the whale shark survives by eating plankton (浮游生物). Weighing up to 20 tons, whale sharks can be found in warm temperature seas.
Basking shark (姥鲨)— Like the whale shark, the basking shark eats plankton by opening its mouth wide and filtering(过滤) feeding. Basking sharks are, on average, about 6—8 meters long but can grow as much as 12 meters in length and weigh up to 4. 5 tons.
Oarfish(桨鱼)— Considered the longest bony fish alive, oarfish are snake-like creatures that live in the depths of the oceans. Named after their long pectoral (胸部的) fins, which look like oars, they can reach a length of 17 meters and weigh about 270 kilograms.
Mola mola(翻车鱼)— This species of sunfish can weigh as much as 2. 5 tons while measuring almost 3. 5 meters, making it the heaviest bony fish, though nowhere near (远非) as heavy as whale sharks and other sharks, which have skeletons made of cartilage(软骨) instead of bones. The mola mola mostly eats jellyfish(水母).
(1)、Which of the following is the largest fish according to the passage?A、The oarfish. B、The mola mola. C、The whale shark. D、The basking shark.(2)、Which word can be used to describe basking sharks?A、Dangerous. B、Peaceful. C、Intelligent. D、Colorful.(3)、Oarfish get their name because ____A、they are bony fish B、they like snakes C、they live in the deep oceans D、their pectoral fins are like oars(4)、Which of the following is NOT true about the mola mola?A、It is a heavy sunfish.

Brenden Sener is a 13-year-old boy from Ontario, Canada. Hebuilt a really cool mini version of Archimedes' death ray.
A death ray may release great energy, generally causing destruction(破坏) or death. A famous ancient Greek (invent) named Archimedes is said to have come up with the idea to use the sun's power as a weapon(武器). He named the device(装置)the Archimedes' death ray.
The Archimedes' death ray had many large concave(凹面的) mirrors positioned to direct sunlight on a single place, heating it up setting it on fire. Think how a magnifying glass(放大镜) can set newspaper on fire by focusing sunlight on it. The death ray did something similar.
It is said that Archimedes' invention (use) to set Roman ships on fire during ancient battles. Sadly, there's no evidence that Archimedes' device ever existed and many have questioned whether it (actual) worked. Brenden Sener's middle school science fair project shows Archimedes' death ray could work.
Brenden Sener created a mini version of the Archimedes' death ray. He used a heating lamp, four small concave mirrors, and a piece of cardboard his experiment. As the mirrors focused the lamp's light to a marked spot on the cardboard, the target(目标) point's temperature (increase)with the addition of each mirror.
But Brenden's aim was not (set) anything on fire, just to prove that it could be possible to use big enough mirrors and sunlight instead of a heating lamp. But such a weapon is not likely to be built in reality.
Making a powerful Archimedes' death ray would be unlikely for several reasons. First, the device would have to be huge in size, making impractical to build. Secondly, it's difficult to accurately hit a (move) target by focusing sunlight on it.

When an artificial intelligence (Al) model is created, it has no knowledge. AI companies, like OpenAI, teach it different things so that it works 1 .
Similar to how babies are taught using various examples like stories, photos, etc. , AI models also learn by2 Imagine showing AI photos of cats and dogs. It will learn to tell the differences between them.
It's not only about 3 ; AI models are trained using data from otherInternet sources like 4 papers, etc.
However, recent news reports show that AI companies are running out of data to train their AI models.
AI companies 5 high-quality data to train their AI models. I magin e such data as a good textbook that helps us learn. Similarly, high-quality data is needed to train AI models.
Recently, AI companies are saying that high-quality data may run out in the next two years. Imagine a situation where you have finished all your school textbooks and have 6 new to read. What would you do then? Would you stop learning there or 7 other sources? So, AI companies are also trying to find other sources to train their AI models.
Open AI is translating some videos to train the latest AI model. Meta has discussed buying a(n)8 publishing house to use all the books to train its AI model. Some are even thinking of using synthetic(合成的) data.
However, these solutions face certain 9 . AI companies are facing criticism(批评) for using public data to train their models. For example, OpenAI has been criticized for using videos made by humans to train Sora, its video-making AI. People want AI companies to get permission (允许) or 10 them before using their data.

What if you could change the plastic spoon you used at lunch into a cup for your water and then change it back to a spoon? That is what researchers at the University of Chicago's Pritzker School of Molecular Engineering had in mind.
The magical material is made up of polymers (聚合物). The researchers heated the plastic only to low temperatures(around 60℃) and then cooled it rapidly.
To test the plastic, they first made it into a spoon strong enough to scoop up peanut butter. After that, the fork was changed into an adhesive(黏合剂), which then became a small claw to pick up objects.
The team published their study in the journal Science on February 1, 2024. The current plastic does have some limitations(局限). Its shape-shifting ability stops working after seven times. But the engineers are unsure how long it remains suitable for reuse. However, they said that once ready, it would be extremely useful, both on the earth and in space.
Now plastic items have to be carefully sorted before recycling. If the pluripotent plastic is widely used in the future, all items could be processed together. This would make recycling a lot easier. More importantly, it could help reduce the amount of single-use plastics that end up in our landfills(垃圾填埋场) every day.
A. They created a material called "pluripotent(多能性的) plastic".
B. The plastic holds its shape for at least a month.
C. It allowed them to create different objects in no time.
D. The spoon was then changed into a fork to pick up cheese.
E. Also, it opens the door to different ways of plastic recycling.
F. If you have this one material, you can turn it into many different things.

A research team from China's Shanghai Jiao Tong University has developed a six-legged guide robot that is expected to deal with the country's shortage of real guide dogs.
"We believe our robot will work as 'a pair of eyes' for visually impaired people, "said Professor Gao Feng from the School of Mechanical Engineering on Thursday.
According to the China Association of Persons with Visual Disabilities, there are about 17. 31 million visually impaired people in China. However, due to high breeding (培育) costs and long training periods, there are reportedly only over 400 guide dogs in service nationwide, which means only one guide dog is available for every 40, 000 visually impaired people in China.
As a strong backup for the real guide dogs, the guide robot can accurately recognize the speech of blind people and reply in less than one second, walking at a maximum (最高的) speed of three meters per second while keeping a stable (稳定的) walking state with little noise.
The robot has visual environmental perception(感知), allowing it to autonomously navigate to its destination, avoid obstacles, and recognize traffic lights. Moreover, with the support of the Internet, it can also serve as a home companion for blind people.
"The primary task of our robot is to establish effective communication with blind people to enable the robot to understand the user's intentions (意图) while maintaining coordinated(协调的) movements, " said Gao. To achieve these goals, the robot uses a perception system of" seeing, hearing, asking and touching" to enable the users to control the robot.
In addition, it is equipped with many kinds of sensors such as laser radar to improve the accuracy of perception in different environments. This means it can walk smoothly on different types of terrain (地形) and guide the blind both indoors and outdoors with no need of Internet, making it easier to use, more stable, and more reliable for blind people.
The guide robot is now undergoing field testing. Gao said, "We have already received orders for 20 units, and believe that it will soon be ready for the market!"
(1)、A visually impaired person is someone who ____.A、isn't able to see in a normal way B、is unable to hear at all or to hear well C、has the disability to communicate D、can't see a rainbow in the sky just after the rain(2)、What's the writer's purpose of writing the third paragraph?A、To tell us our country is short of guide dogs.

I magine you are in a field at night, and suddenly, you see lots of little lights around you. You have just found a gathering of fireflies, and their twinkling lights are like a secret language. This nighttime lights show, especially in the forest, has fascinated people for a long time. Let's explore the mystery of fireflies.
Did you ever wonder how fireflies make their tails glow? The special power of fireflies to make light is called bioluminescence (生物发光), a special ability that some animals, like fireflies, have to create their own light through a chemical reaction. It happens when two chemicals in their bodies combine (结合) and generate a chemical reaction that produces light.
However, why do fireflies need to make light in the dark? Now, imagine you are a firefly looking for someone special in the dark. How would you find Mr. or Ms. Right? Fireflies use their glowing lights to send "hello" messages to each other. Each kind of firefly has its own special pattern of flashes, like a secret code. They use their lights as an invitation to get to know each other better, so that they can mate and produce the next generation of fireflies.
But fireflies do not just use their lights for conversations. They also use them to stay safe. Imagine you are an adult firefly in the shadows, and a big spider is trying to catch you. What do you do? You turn on your light! Your bright glow is like a sign that tells the spider" I taste disgusting. Do not eat me!"
This story of fireflies tells us how amazing and wonderful the natural world is. Exploring the world of fireflies helps us see how important it is to take care of nature and all its fascinating organisms(生物), no matter how small they are.
(1)、The writer explains how fireflies make light ____.A、by explaining in chemistry B、by giving an example C、by physical experiments D、by showing some facts(2)、Why do fireflies need to make light in the dark?a. To help them stay in safety.
b. To see their way clearly at night.

Anyone with a mobile phone has likely dropped it in water or been caught in a rainstorm. And many people seem to think that putting a wet phone in a bag of rice will rescue it.
However, Apple recently warned against doing just that. The technology company said it is a bad idea because small particles(颗粒) of rice can get into the phone and cause damage.
So what should you do instead? If the phone is dropped in water, dry it with a towel or clean cloth, and even a shirt will do. Turn the phone off if you can. Remove its SIM card. Remove the phone's cover. Remove the battery, if possible. And let everything dry at room temperature, perhaps with a fan running. Since you cannot take the phone apart, Apple suggests tapping the phone against your hand with the connecting ports(端口) facing down so water can flow out.
If your phone is dropped in seawater, treated water, or a drink, Samsung suggests keeping it in clean water for a few minutes. Doing that will remove any salt or substances that could hurt the phone. Both Apple and Samsung say it's best to leave the phone out in an open area to dry it out. More importantly, do not use a hair dryer or put the phone in a freezer.
Most newer phones are not waterproof(防水的) but they are water-resistant. Apple says its newest phones can survive 30 minutes in up to 6 meters of water. Samsung's phones can last for the same amount of time in about5 meters. But remember that the water resistance will decrease over time.
The phone manufacturers say it is hard to know when phones are completely dry. But it will likely take a few days. Samsung advises bringing the phone into a service center for inspection even after it's been air-dried.
(1)、To rescue a wet phone, Apple tells us to ____.A、take it apart at once B、make it dry in the sun C、put it in a bag of rice D、tap your hand on the phone(2)、If a phone is dropped in seawater, Samsung advises ____.A、drying it with a lot of salt B、letting it stay in a freezer C、blowing it with a hair dryer D、putting it into clean water for a while(3)、A phone is water-resistant, which means ____.A、it can survive in water forever B、it can get wet for a short time. C、it can't stay in water for a minute D、it can last a long time in deep water(4)、What is the passage mainly about?A、How to keep a wet phone away from danger. B、What to do if a wet phone has been put in rice. C、Why we should buy a phone that is waterproof. D、Who can help us when a phone is dropped in water.
