As spring advances across the Midwest, a new study looking at blooming(盛开的) flowers suggests non-native plants might live longer than native plants due to climate change.
The study-led by researchers at Indiana University and Michigan State University-has shown warming temperatures affect native and non-native flowering plants differently, which could change the look of local place over time. "When a plant flowers determines whether it will be pollinated(授粉) by bees or other insects and how much time it will have to produce seeds. Our data makes me worry that we will have a very weedy world in our future, " said the study's lead author Jen Lau, an associate professor in Indiana University.
The researchers' findings suggest non-native plants may be better at shft~g their flowering time compared to native plants. These differences are thought to influence a plant's success both now and in future warmer environments.
Lau and her students simulated(模拟) global warming in fields planted with 45 native and non-native plants. Some areas were warmed by infrared (红外线的) heaters, while other areas were not. Lau's lab surveyed all plants to determine when they first flowered and how long they flowered.
When plants were grown in warmed plots simulating the climate change expected in the Midwest by the end of the century, the researchers found that non-native plants flowered more than 11 days earlier on average. In contrast, native plants didn't change flowering times at all when warmed.
They also found earlier-flowering non-native plants had greater geographic spread, suggesting that flowering earlier may help promote successful occupation across large areas.
The findings suggest important differences in how native and non-native plants respond to climate change.
(1)、What does the new study find about native plants compared with non-natives7A、They may have a longer life cycle. B、They are likely to have more flowers. C、They are more adaptable to climate change. D、They may be at greater risk from climate change.(2)、What do Jen Lau's words in paragraph 2 suggest?A、She's quite sure that a weedy world is waiting for us. B、Plants may lose the ability to flower in the future. C、The timing of a plant's flowering is key to its life cycle. D、A plant's flowering time almost has no effect on its pollination.(3)、What does the underlined word "shifting" in paragraph 3 probably mean?A、Changing. B、Postponing. C、Arranging. D、Predicting.(4)、What is paragraph 4 mainly about?A、How global warming affected plant species. B、How the researchers tested their supposition. C、How to keep the warmth of the planted fields. D、How to determine the flowering times of plants. -

An Oklahoma man who was once diagnosed(诊断) with lung cancer and told he only had three months to live says he's now cancer-free thanks to a cheap deworming(驱虫) drug meant for dogs.
Joe Tippens was diagnosed with lung cancer in 2016. Despite treatment for the disease, by January of 2017,the cancer had spread to other organs. Doctors advised him to go home and say his goodbyes because he only had three months. Tippens thought he was going to die, and with nothing left to lose, he was willing to try anything in hope of a miracle(奇迹), even a dog dewormer called fenbendazole.
The desperate cancer sufferer came across the strange treatment while reading a post online. The post catching his eye read "If you have cancer or know someone who does, give me a shout". Joe had already signed up for an experimental treatment that doctors said wouldn't save him but might help him live a little longer. But he decided that getting in touch with that poster couldn't hurt, either.
To his surprise, that person was a vet(兽医), who told Joe scientists had accidentally discovered a dog deworming drug seemed to attack cancer cells in mice. One of the scientists conducting the research had been diagnosed with brain cancer, but she started taking fenbendazole and within six weeks her cancer disappeared. Joe decided to have a try.
Tippens continued receiving treatment in hospital, but he also placed an order for fenbendazole. He didn't tell his doctors about it, though. Three months later, when he had another scan to check the spread of his cancerl he was shocked to learn that there was no sign of the cancer anywhere in his body.
There are also studies that suggest the drug basically starves cancer cells and kills them. Still, many doctors are sceptical about the drug and recommend that patients stick to classical treatments.
(1)、Why did doctors suggest Joe Tippens go home?A、His disease had worsened faster than expected. B、He was unwilling to try the new treatment. C、He couldn't afford treatment in hospital. D、His life would soon come to an end.(2)、How did Tippens know the strange treatment?A、From the Internet. B、From a familiar vet. C、From one of his doctors. D、From another cancer sufferer.(3)、Tippens took the dog deworming drug____.A、in secret in his own home B、under the guidance of a scientist C、without his doctors' knowledge D、regardless of his doctors' opposition(4)、What does the last paragraph imply about fenbendazole?A、It cures cancer by swallowing cancer cells. B、Its cancer-curing functions are controversial. C、It is widely used in classical cancer treatment. D、Its unusual effects have been proved on several patients. -

Superman Learns How to Ride
It was the summer of 1967, and the moment was nearing when I would cast off(丢弃) my training wheels and learn to ride a bike.
As an adventurous little boy, I sure put my overactive imagination to good use. I would pretend to be the bookish reporter, Clark Kent. Then, at the first sign of something wrong, I disappeared and emerged moments later with a red towel hanging from the collar of my dirty blue T-shirt and an ironed-on letter "S"on my chest.
"This is a job for Superman!"I would cry out as I flew to meet imaginary dangers that threatened the world.
"Hey,Superman, when are you going to learn to ride a bike?" the neighborhood kids would taunt(奚落)as they rolled past. "The Man of Steel still uses training wheels!" they laughed.
As I watched them ride away, I realized I was being left behind. To claim my place among their ranks, I needed to cast off my training wheels and learn to ride with the big kids. I turned to my father for help.
"Okay, I'm going to let go, and you just remember to balance,"Dad advised patiently on my tenth try. Suddenly I was riding! I dared to smile as my father's shouts of encouragement faded into the background. My smile widened. Victory was mine.
You are going to fall. The thought was at first a whisper and then grew louder and more convincing until I believed it must be true. After all, I had always fallen before. Why should this time be any different? Fear seized me, and my confidence weakened and I couldn't grasp the handlebars(把手)tightly. Sure enough, I fell to the grass.
"You almost had it,"Dad said, catching his breath. "You are seized with a sense of fear so you fell. "
"I quit,"I said angrily, trying to fight back the tears of frustration. "I don't want to learn to ride. "
注意:1. 续写词数应为150左右;2. 请按如下格式在答题卡的相应位置作答。
Paragraph 1:However, on thinking of Superman, I decided to behave like a real hero.

18、 阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为
多余选项。
Do you feel bitter about others'personal integrity around? But fortunately, there are some ways to tell if someone is lying to you.
They Touch or Cover Their Mouth
If the person you're talking to put their hand over their mouth, it's a good signal indicating(表明)they are unwilling to answer a direct question or reveal something true. And it doesn't need to be as obvious as slapping hands over their mouths. A small gesture is enough to give away a liar.
They Repeat Words or Phrases
When a person is telling the truth, they can recall everything without thinking about it. On the other hand, when someone is telling a half-truth or a total lie, they often repcat themselves over and over to convince you of their words.
They Use Inconsistent Gestures
Inconsistent gestures bring a visual element to the concept you're trying to convey, like shaking your head when you say no, or nodding to indicate yes. Inconsistent gestures, therefore,are those that don't go with this concept. For example, they say yes while avoiding any eye contact, lowering their heads.
Keep in mind that there is no fixed proof that someone is lying. It's also crucial (重要的)that you understand the person's usual behavior before assuming they're lying, as certain habits like pointing or over-sharing may be entirely typical of them.
A. They tend to avoid direct questions by looking around.
B. It is common for liars to use rude gestures like pointing.
C. Big liars may expose the truth through their body language.
D. Surely you do since they are dishonest with you involuntarily.
E. They're unconsciously putting a barrier between themselves and you.
F. It's also a strategy to help the liar buy time to compose the next part of their story.
G. Nevertheless, it is a good place to start if you want to learn to recognize small clues.

A wise driver keeps an eye on the fuel indicator(指示器), to make timely stops at filling stations. For drivers of electric cars, though, those stations are scarce. The facility needed for refilling batteries has yet to be developed, and the technology that facility will use is still not available at the moment. Most electric cars are equipped with plugs. But plugs and their connected cables and charging points bring problems. The cables are easy to trip passers-by. The charging points lead to more street jams. And the copper wire involved. attracts thieves easily. Many engineers would, therefore, like to develop a second way of charging electric cars—one that is wireless and can thus be buried underground.
Electromagnetic induction(电磁感应),the fundamental principle behind wireless charging, was discovered by Michael Faraday in 1831, and is widely used in things such as clectric motors and generators. Faraday observed that moving a conductor through a magnetic field generated a current in that conductor. Further investigations showed that this also works if the conductor is fixed and the magnetic field is moving. Since electric currents generate magnetic fields, and if the current changes so does the field, a changing current creates a field that is constantly moving. This means that running such a current through a conductor will generate a similar current in another, nearby, conductor. That generated current can then be used for whatever purpose an engineer chooses.
In the case of electric car charging, the first conductor is a length of copper wire. This is rolled up around a piece of ferrite(铁氧体) that strengthens the magnetic field generated. The whole device is packed in a flat case that can be easily buried underground. When a car equipped with a suitable "pickup"stops or parks above this device, and changing current is fed into it, a similar current is generated in the pickup. This is then turned into direct current, and is used to charge the car's battery. The principle is thus pretty simple. But only in recent years has it become practical to use in electric cars.
(1)、What does Paragraph 1 mainly talk about?A、The charging facility is in urgent need currently. B、The wise drivers must observe the fuel indicator. C、The disadvantages are various for vehicles to charge. D、The importance of wireless charging cannot be ignored.(2)、What can we know from Paragraph 2?A、No current will be generated without magnetic field fixed. B、Electric induction is of great importance to wireless charging. C、A changing current hardly creates a constantly moving field. D、Wireless charging was put into use in all cars in recent years.(3)、How does the device charge a car?A、The current generated in the pickup charges the car. B、The underground ferrite gives direct electricity to the car. C、The rolled conductor produces electricity to charge the car. D、The whole device conveys direct electricity through the wire.(4)、What is the best title of the passage?A、The Principle of Wireless Cars B、The Present Use of Wireless Charging C、The Wireless Charging Is Approaching D、The Generation of Current in Electronic Cars -

In the 1997 movie Contact, a scientist, played by actress Jodie Foster, detects a radio signal—the first communication from an extraterrestrial(外星的)civilization. That story, composed by Carl Sagan, is a fiction. But the search for such a signal is not a crazy story. Real scientists look to the sky, using powerful radio telescopes, hoping to hear even a whisper of a radio signal from one of our neighbor planets.
Indeed, a recent report of a transmission originating from Proxima Centauri, the closest star to our own, was reported by the British newspaper The Guardian in December. The source of the story is not a scientific paper, but instead it seems to have been leaked by an unknown source. The claim of a signal, if it turns out to be truly a sign of extraterrestrial intelligence, would be one of the most important discoveries of all times.
In April and May of 2019, the 64-meter-wide Parkes radio telescope, located in Australia, was recording radio transmissions from the direction of nearby star Proxima Centauri. Over the course of hours, the telescope documented data from the star every half an hour, before staying away to look at a different direction. This procedure, called "nodding" was used to make sure that any observed signal is coming from a particular direction, rather than just random radio noise.
This signal was not immediately noticed; it was over a year after the data was recorded that Shane Smith, an assistant with Breakthrough Listen, found it buried in the telescope's recordings. This was in late October 2020. So, what exactly was seen? It was a radio signal at a single frequency, specifically 980. 002 MHz. It was observed to have originated in a small patch of the sky, about half the diameter(直径)of the full moon, centred on Proxima Centauri.
First and foremost, it is important to note that astronomers think it is highly unlikely that the signal is caused by space aliens trying to communicate with us. However,astronomers mentioning the significance of the signal cannot be ignored.
(1)、Why is the movie Contact mentioned in Paragraph 1?A、To show the close connection between fiction and signals. B、To introduce the topic of a radio signal from a near planet. C、To stress the importance of the extraterrestrial civilization. D、To persuade people to pay more attention to radio signals.(2)、How did the radio telescope collect data?A、By recording the data every 30 minutes. B、By staying away at a different direction. C、By analyzing the direction of the signals. D、By focusing on some random radio noise.(3)、What do we know about the radio signal found by Shane Smith?A、It was sent by some space aliens. B、It lay in the centre of Proxima Centauri. C、It was noticed as soon as it was observed. D、It changed rapidly with the passing of time.(4)、What might be talked about in the paragraph following the text?A、How aliens think about the radio signal. B、The potential results of the radio signal. C、The importance of finding the radio signal. D、How other countries react to the radio signal.
