Much of Earth is unexplored. An ocean census (普查) hopes to change that.
"Earth" has always been an odd choice of name for the third planet from the Sun. After all, two-thirds of its surface is covered not by earth at all, but by oceans of water.
Because humans are land animals, most of the Earth remains under-explored. Marine (海洋的) biologists think the oceans might host more than 2 million species of marine animals, of which they have so far identified perhaps a tenth.
A new initiative hopes to change this. Launched in London on April 27th, Ocean Census aims to discover 100, 000 new species of marine animal over the coming decade. It is backed by Nekton, a British marine-research institute, and the Nippon foundation, Japan's biggest charitable foundation. Its first ship, the Norwegian icebreaker Kronprins Haakon, set sail on April 29th, bound for the Barents Sea.
The initiative is happening for two reasons. One is that the longer scientists wait, the less there will be to identify. Climate change is heating the oceans, as well as making them more acidic (酸的) as carbon dioxide dissolves goes into the water. Already around half the world's coral reefs (珊瑚)—thought to be home to around 25% of all ocean species—have been lost. Oliver Steeds, Nekton's founder, says that one of Ocean Census's priorities will be identifying species thought to be in the greatest danger from climate change. The second reason is technological. Marine biologist s find about 2, 000 new species a year, a rate hardly changed since Darwin's day. Ocean Census is betting it can go faster.
Exactly what the new effort might turn up is impossible to predict. But history suggests it will be fruitful. Half a century ago scientists discovered hot vents (喷口) on the sea bed. These days, such vents are one possible candidate for the origin of all life on Earth. There are more practical benefits, too. Many drugs, for example, come originally from biological substance. An ocean full of unidentified life will almost certainly prove a rich mine from which to mine more.
(1)、Why is "Earth" an odd choice of name for the third planet from the Sun?A、Its climate is changing rapidly. B、Humans have not explored much of it. C、Most of its surface is covered by water. D、It hosts a large number of marine animals.(2)、What can we infer from paragraph 5?A、The rate of discovering new species won't change. B、The new initiative will mainly focus on coral reefs. C、Climate change has a great impact on marine species. D、Scientists have identified nearly all the species in the ocean.(3)、What might be the potential benefits of the Ocean Census according to the last paragraph?A、It may result in a reduction in overfishing. B、It may lead to the discovery of new drugs. C、It may contribute to the advancement of technology. D、It may prove the oceans are our life-support system.(4)、What's the best title for the text?A、The Endangered Planet B、Reducing Sea Pollution: A Global Initiative C、How to Protect the Oceans? D、The Misnamed Earth: Exploring the Ocean's Secrets -

Myopia, also known as nearsightedness, has become a lot more common in recent decades. Some even consider myopia an epidemic (流行病). But what causes myopia and what reduces it?
While having two myopic parents does mean you're more likely to be nearsighted, there's no single myopia gene. That means the causes of myopia are more behavioral than genetic.
Scientists have learned a great deal about the progression of myopia by studying visual development in baby chickens. They do so by putting little hats on baby chickens. Lenses (镜片) on the face of the hats cover the chicks' eyes and are adjusted to affect how much they see.
Just like in humans, if visual input is wrong, a chick's eyes grow too large, resulting in myopia. And it's progressive. Blur (模糊) leads to eye growth, which causes more blur, which makes the eye grow even larger, and so on.
Two recent studies featuring extensive surveys of children and their parents provide strong support for the idea that an important driver of the increase in myopia is that people are spending more time focusing on objects immediately in front of our eyes, whether a screen, a book or a drawing pad.
Other research has shown that this unnatural eye growth can be interrupted by sunlight. A 2022 study, for example, found that myopia rates were more than four times greater for children who didn't spend much time outdoors—say, once or twice a week—compared with those who were outside daily. At the same time, kids who spent more than three hours a day while not at school reading or looking at a screen close-up were four times more likely to have myopia than those who spent an hour or less doing so.
Fortunately, just a few minutes a day with glasses that correct blur stops the progression of myopia, which is why early vision testing and vision correction are important to limit the development of myopia.
(1)、What can we learn from the study on baby chickens?A、Myopia in chicks is not progressive. B、Myopia is mainly caused by genetic factors. C、Visual input affects the growth of a chick's eyes. D、Lenses can prevent chicks from developing myopia.(2)、What might be the main cause of myopia according to the text?A、Absence of enough sleeping hours. B、Too much screen time. C、Poor and unbalanced diet. D、Lack of high-intense activities.(3)、What's the main idea of paragraph 6?A、Outdoor light helps prevent myopia. B、Reading is the direct cause of myopia. C、Researchers have found a cure for myopia. D、Children should play outdoors twice a week at least.(4)、What is the author's attitude towards early vision testing?A、Unclear. B、Approving. C、Doubtful. D、Dismissive. -

Standing on the South Pole at the start of the year with the wind blowing across the Antarctic, travel blogger Johnny Ward felt a wave of relief.
Just a week before, in early January 2024, he'd struggled through snow and ice to climb to the top of the Vinson Massif, Antarctica's highest peak. Years before, in 2017, he'd become the first Irish person to visit every country in the world.
Now, after decades of traveling and mountaineering, Ward could claim another world first—the Ultimate Explorer's Grand Slam (大满贯), which involves reaching the highest peak on every continent, and visiting both the North and South Poles in addition to visiting every country.
"I feel relieved," Ward recalled as he slowly made his way back to his home in Thailand after climbing to the top of the Vinson Massif and then setting foot on the South Pole. "But also I'm aware I'm a normal guy, not a world-class athlete, so I guess it was more about resilience and determination more than any ability. Although I met with lots of barriers, I overcame them one by one."
Ward had previously devoted a decade of his life, between 2007 and 2017, to visiting every country in the world. The incredible journey saw him hitchhike (搭便车) a ride on a container ship from Oman to Socotra in Yemen, travel overland from Cairo to Cape Town and travel from South Korea to Australia by bus and boat.
"It had been a huge life goal, over a decade of my life, and then when I finished that I was aimless and had no idea what to do next," he said. "I started eating badly, drinking too much, putting on weight and I ignored my business."
Ward decided that the best way to overcome this was to challenge himself again. He began running ultramarathons (超级马拉松) and climbing mountains, and soon found that with extreme purpose and direction, he was back to loving life again.
So where will Ward go next? Space? The bottom of the Mariana Trench, the deepest point of the ocean? "All good things come after suffering, and I want to share that with people. So that's the next plan," he said.
(1)、What did Johnny Ward achieve in early January 2024?A、He climbed to the highest peak in Antarctica. B、He set a new record for traveling in Antarctica. C、He became the first person to visit the South Pole. D、He became the first Irish person to visit every country.(2)、What does the underlined word "resilience" in Paragraph 4 refer to?A、The ability to bounce back from difficulties. B、The quality of being strong and honest. C、The skill of achieving goals quickly. D、The power to control one' s emotions.(3)、How did Johnny Ward feel after achieving his life goal in 2017?A、Relaxed. B、Satisfied. C、Lost. D、Excited.(4)、Which of the following can best describe Johnny Ward?A、Helpful and motivated. B、Athletic and generous. C、Proud and self-centered. D、Determined and strong-willed. -

12、 阅读短文,回答问题
A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture. A new finding suggests that parents, social workers, psychologists and lawyers should be careful with their hands as well as their words.
Gestures can be as informative as speech, but hand gestures are so common that we rarely notice we're using them.
While the recall of both adults and children are easy to react to suggestion, the memories of children are known to be particularly influenced, said lead researcher Sara Broaders of Northwestern University. Kids are used to looking to adults to tell events for them and can be misled even if not intentionally(故意地).
Previous research, for example, has shown that detail-loaded questions often cause false answers; when asked, say "Did you drink juice at the picnic?", the child is likely to say "yes" even if no juice had been available. It is not that the child is consciously lying, but rather the detail is quickly formed into his or her memory.
To avoid this problem, social workers have long been advised to ask children only open-ended questions, such as "What did you have at the picnic?" But an open-ended question paired with a gesture, briefly meaning a juice box, is treated like a detailed question. That is, children become likely to answer falsely.
And it isn't just a few kids: 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture. Gestures may also become more popular when talking with non-fluent language users, such as little kids, Broaders said as hand movements can impart meaning of unfamiliar words and phrases. "It certainly seems reasonable that adults would gesture more with children. "
In general, Broaders advises parents and other adults to "Try to be aware of your hands when questioning a child about an event. Otherwise, you might be getting answers that don't reflect what actually happened. "
(1)、What do we know about gestures according to the text?A、They have a certain effect on children. B、They are rarely used by people. C、They have no function at all. D、They are often used by social workers.(2)、Why are kids easy to be misled by gestures according to Sara Broaders?A、These gestures are very attractive. B、Their memories are affected easily. C、Children are easy to tell lies. D、These gestures are used frequently.(3)、What does the underlined word "impart" in Paragraph 6 mean?A、Separate. B、Tell apart. C、Confuse. D、Pass on.(4)、Which of the following can be the best title of the text?A、Gestures—a Useful Way of Education. B、Gestures Can Mislead Children. C、Gestures Mean Adult's Directions. D、Gestures Affect Children Much. -

A 15-year-old Colorado high school student and young scientist who has used artificial intelligence (AI) and created apps to address polluted drinking water, drug addiction and other social problems has been named Time Magazine's first-ever "Kid of the Year".
Rao told The Associated Press in an interview from her home that the prize is nothing that I could have ever imagined. And I'm so grateful and just so excited that we're really taking a look at the upcoming generation and our generation, since the future is in our hands.
Time said Rao stood out for creating a global community of young innovators and inspiring them to pursue their goals. Rao insisted that starting out small doesn't matter, as long as you're passionate about it.
She told Time contributing editor Angelina Jolie in an interview that her science pursuits started early as a way to improve social conditions. The drinking water crisis in Flint, Michigan, inspired her work to develop a way to detect pollutants and send those results to a mobile phone, she said.
"I was like 10 when I told my parents that I wanted to research carbon nanotube sensor technology at the Denver Water quality research lab, and my mum was like, A what?" Rao told Jolie. She said that work is going to be in our generation's hands pretty soon. "So if no one else is gonna do it, I'm gonna do it. "
In a world where science is increasingly questioned or challenged, Rao insisted that its pursuit is an act of kindness, the best way that a younger generation can better the world.
"We have science in everything we're involved in, and I think that's the biggest thing to put out there, that science is cool, innovating is cool, and anybody can be an innovator. " Rao said, "Anybody can do science. "
(1)、What did Rao think of the award she received?A、It was a mark of social progress. B、It was a recognition of her work. C、It was an inspiration to the youth. D、It was a title beyond her expectation.(2)、Why would Rao start to pursue science?A、To encourage people to aim high. B、To pursue her passion for research. C、To change the society for the better. D、To stop science from being questioned.(3)、Which word can best describe Rao?A、Cool. B、Kind. C、Brave. D、Creative.(4)、What's the purpose of the text?A、To report a young genius. B、To introduce new inventions. C、To improve social conditions. D、To present artificial intelligence. -
