1 . A little boy almost thought of himself as the most unfortunate child in the world because poliomyelitis (小儿麻痹症) made his leg lame and his teeth uneven. He seldom played with his classmates; and when the teacher asked him to answer questions, he always lowered his head without a word.
One spring, the boy’s father asked for some saplings (树苗) from the neighbor. He told his children to plant a sapling each person. The father said, “Whose seedling grows best, I will buy him or her a favorite gift.” The boy also wanted to get his father’s gift. But seeing his brothers and sisters carrying water to water the trees happily, anyhow, he hit upon an idea: he hoped the tree he planted would die soon. So watering it once or twice, he never attended to it.
A few days later, when the little boy went to see his tree again, he was surprised to find it not only didn’t wilt, but also grew some fresh leaves, and compared with the trees of his brother and sister, his appeared greener and more vital. His father kept his promise, bought the little boy his favorite gift and said to him: from the tree he planted, he would become an outstanding botanist when he grew up.
Since then, the little boy slowly became optimistic. One day, the little boy lay on the bed but couldn't sleep. Looking at the bright moonlight outside the window, he suddenly recalled what the biology teacher once said, plants generally grow at night. Why not go to see the tree? When he came to the courtyard on tiptoe, he found his father was splashing something under his tree with a ladle (勺子). He returned to his room, tears running down his face.
Decades passed. The little boy didn’t become a botanist, but he was elected President of the United States. His name was Franklin Roosevelt.

2 . Rachel Carson was concerned about what was happenig to the environment. So in her book Silent Spring, she warned that some chemicals were poisoning the air, the water, the earth, and all its creatures. She imagined a time when spring would not bring the rebirth of flowers, trees, and the songs of birds. The book became a bestseller, and Ms. Carson was in great demand as a speaker. People lisened to her because what she said made sense, and because she was a scientist who knew her facts.
Rachel Carson was primarily interested in the world of sea and shore, so she became a marine biologst for the government. She studied and recorded facts about the sea' s plant and animal life, their special characteristics, and the nature of their environments. In 1951, she wrote The Sea Around Us, which brought her honors, fame, and respect around the world.
Ms. Carson then devoted herself full-time to research and writing. One thing much on her mind was the effect of modern technology on the natural environment. One day, a distressed friend wrote her to say that a plane spraying(喷洒) DDT had flown over her yard, and the next day several birds lay dead. Carson decided to act.
For four years she studied the use of pesticides(杀虫剂) in the United States, and then she wrote Silent Spring.
In her book Ms. Carson said that these pesticides would harm much more than insects. She explained that these poisons would pollute the environment. “Even if their effects are not immediately observable, they remain for years in the water and the soil, and they become part of the food eaten by animals and humans.
Besides, after a time, insects develop immunity to pesticides,” she said.
Recent studies have shown that pesticides can affect human brainwave activity and cause loss of memory and inability to concentrate. We should still remember Rachel Carson’s words, “I think we are challenged as we have never been challenged before to prove our mastery, not of nature, but of ourselves.”

3 . One of the most successful, influential and beloved women in American history, Eleanor Roosevelt once said that she had one regret: she wished she had been prettier. Who hasn’t felt the same way? We are all too aware of our physical imperfections. To overcome them, we spend billions upon billions every year. Why do we care so much about how we look? Because it matters. Because beauty is powerful. Because even we learn to value people mostly for being kind and wise and funny, we are still moved by beauty.
Aristotle said, “Beauty is a greater recommendation than any letter of introduction”. It’s not fair, but it’s true. We simply treat beautiful people better than we do others. Attach a photograph of a beautiful author to an essay, and people will think that it is more creative and more intelligently written than exactly the same essay accompanied by the photo of a homely author. As children, beautiful people are more likely to become favorites with parents and teachers. Later, they are more likely to get good jobs. Attractive people in need are more likely to receive help from strangers.
These days, women and men both rely on advanced technology to improve their beauty. Wrinkles can be stretched away with a face lift. Special injections can make lips look young and plump (丰满的). Besides being a sign of youth, good skin also means that the person is likely to be healthy. Still, it is possible to go too far. At the end of the 19th century, some women even had their ribs (肋骨) removed so they’d have that perfect narrow waist.
Our sensitivity to physical beauty is not something we can control at will. We are born with it. Experiments showed that even small infants prefer to look at attractive faces. Before they have met a single supermodel, before they have watched a single TV show, before they have opened up a single fashion magazine, they are drawn to the same faces which adults have judged to be attractive.
There are more important things in life than beauty. But as Nancy Etcoff says, “We have to understand beauty, or we will always be enslaved by it.” If you aim to be wise and kind and funny, it doesn’t mean that you can't also try your best to look beautiful. There’s no reason to feel guilty about being moved by beauty’s power. It moves us all.

4 . A trip to the theater, museum or art gallery could help you live longer. And the more often you get that culture, the better the results are, a new study suggests.
Researchers from University College London (UCL) did the research on more than 6,000 adults in England age 50 years and older. How often an individual engaged in art activities was measured at the start of the study in 2004 to 2005. Participants were then followed up for an average of 12 years, during which time deaths were recorded using data from the UK’s National Health Service (NHS). They found that people who engaged in the arts more frequency had a 31% lower risk of dying early when compared to those who didn’t. Even going to the theater or museum once or twice a year was linked with a 14% lower risk.
The study looked at a range of economic, health and social factors to try and explain why there is a link between “arts engagement and living longer. Part of the reason, the study said, comes down to social and economic differences among those who go and don’t go to museums, exhibitions and art galleries. Wealth, they found, explained about 9% of the association. Cognitive (认知的) differences and mental health also played a role. Things like free time and occupational status made no difference, said Fancourt.
Engaging with the arts can act as a buffer against stress and build creativity that allows people to adapt to changing circumstances. It also helps people access emotional support and information that helps people age more successfully. “We also thought that a greater sense of purpose could play a role,” she said. “It can have wide ranging benefits and support healthier lives lived longer.”
A world health organization last year found that both receptive participation, like visiting a museum, and active participation, like singing in a choir, had health benefits. An editorial that accompanied the paper said that everyone should have the chance to take part in cultural activities and said the study added weight to growing concerns about the decline in arts subjects in schools and universities.

5 . Many parents worry that showing negative emotions in front of their children will cause them to suffer. For example, children may end up thinking it's their fault or simply "catch" the emotion. Indeed, this worry has a sound basis — the phenomenon of “emotional contagion"（情绪感染）is real, and one recent study found that parents can transfer their fear of going to the dentist, for example, to their children.
On the other hand, there is the natural idea that we should “be real" with our children, and that they will benefit from watching a parent who struggles and eventually deals with their negative emotions like any other human being.
There are three concepts to consider when it comes to emotional display in front of children: suppression （压抑），"uncontained" expression, and talking about emotions. Suppression of emotion is when you hide the outward signs of an emotion. Unfortunately, it doesn't work very well — the act of suppressing your emotion actually increases your blood pressure. Observers can pick up on your distress despite your efforts to hide it, making them feel stressed. The recent research has also found that when parents feel negative emotions and keep them from their children, they experience lower relationship quality and decreased responsiveness to their child's needs.
On the other hand, “uncontained" expression of anger and sadness by the parent is also not salutary for the child. Uncontained means high intensity emotion, with no attempts to regulate or take ownership of it. Shouting, smashing （摔）things and blaming someone else for "making you angry" are all example of this .
So, what is the middle ground? That would be talking about emotion taking ownership of them and showing your child that you are trying to deal with them. Classic research found that six-year-old kids had better emotional understanding and perspective-taking skills if their mothers had talked to them about their emotions at the age of three. In fact, the more the mothers had talked, the better the outcome would be.
So next time you feel sad, angry or frustrated and your child is watching you expressing emotion, do explain what's going on in terms they can understand.

6 . Scientist， conservation organizations and government trying to stop the trend of extinction （灭绝） often focus on protected areas such as national parks and wildlife preserves. But with as many as million species（物种） at risk， this plan of action may not be enough to conserve wildlife.
Slowing the mass extinction that now appears to be underway will require more creative means of coexisting alongside wild plants and animals. A new study indicates the effectiveness of some such approaches by examining some lands managed by indigenous groups.
“ We show really strongly that， from a biodiversity standpoint in terms of species richness，indigenous － managed lands are at least comparable to protected areas， ” says biologist Richard Schuster of Carleton University. And in some places， they are better than parks and preserves －even though indigenous communities may use their lands’ resources by hunting or searching for food.
Schuster and his team analyzed more than 15，000 areas in Australia， Brazil and Canada. They found that the total diversity of wildlife was highest on lands either managed or co － managed by indigenous groups， while randomly selected areas with no formal protection were the least bio－diverse. For threatened species in particular， indigenous lands scored slightly higher than protected lands on overall species richness in Brazil and Canada， as well as higher for threatened animals in Australia.
Each country has a different geography， climate and history. Yet remarkably， Schuster says， the best indicator for species diversity is whether a given area was managed by an indigenous community. He pointed out that practices such as sustainable（可持续的） hunting， fishing and searching， as well as burning， are more likely to occur in such areas. Don Hankins， an ecologist at California State University，agrees. “ there’ s probably going to be more of a connection to the land， ” he says， “ and a use of the land for the things that are there， compared to a national park. ”
“ It’ s really important to listen to the people who live on the land and have them drive the stewardship efforts going forward， ” Schuster says， adding that partnering with indigenous communities may enable the world’ s countries to better meet a wide range of conservation goals： “ We really need all the help we can get as a global community to prevent species extinction that we’ re facing right now. ”

7 . "When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.
Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental non¬governmental organization, and put his plan for an ocean cleanup device into action.
After years of research and develop¬ment in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（挡板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.
Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.
"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持续的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"
1. The underlined word “match” in Paragraph 2 probably means “_________”.| A．compare | B．equal |
| C．measure | D．cover |
| A．To collect ocean plastic waste. |
| B．To help to invent System 001/B. |
| C．To protect the living environment of fish. |
| D．To do research on the ocean environment. |
| A．It can collect and recycle garbage at the same time. |
| B．It can only gather ocean waste which floats on the water. |
| C．It aims to clear up the Great Pacific Garbage Patch in five years. |
| D．It is an ocean-cleaning device which has already been put to use. |
| A．Young generations care less about the environment. |
| B．The future ecology of the oceans is deeply worrying. |
| C．People should work hard to decrease plastic pollution. |
| D．It's quite difficult to repair the damage to the environment. |
8 . Like clockwork, nearly every fourth February includes one extra day. February 29th, otherwise known as Leap Day, isn’t exactly a holiday. Instead, it’s there to keep your calendar consistent with the earth’s rotation (旋转) around the sun.
According to History, com, Roman emperor Julius Caesar is the “father” of Leap Year. Until he came along, people used a 355-day calendar, which was 10.25 days shorter than the solar year. Roman officials were supposed add an extra month every now and then to keep the seasons exactly where they should be. But that didn’t work out all that well. When special occasions started shifting into different seasons around 45 BCE, Caesar consulted with astronomers and decreed (下令) that the empire should use a 12-month, 365-day calendar, which he named after himself, Caesar’s Julian calendar included a Leap Day every four years.
Though Leap Day keeps your calendar in line with the earth’s rotation around the sun, it causes a different kind of problem for leapsters. When should these February 29th babies celebrate their birthdays during the other three-quarters of their lives? Some party on February 28th, while others prefer a two-day celebration that spans the last day of February and the first day of March.
Leap Day can be a nuisance in the legal system. In 2006, a court in Massachusetts was deciding whether criminal John Melo could be released a day early since his 10-year sentence included a Leap Day. In the case, the judge decided that since the man was sentenced to prison for years, not days. Leap Day didn’t make a bit of difference.
Though a few timekeepers have pushed for calendars that don’t include Leap Day, almost all astronomers and societies agree that Leap Day is the best method to keep the calendar on track.
1. Why was Leap Day created?| A．To celebrate special occasions. | B．To honor Emperor Julius Caesar. |
| C．To keep pace with the solar year. | D．To keep track of all the seasons. |
| A．It is sometimes delayed. | B．It lasts at least two days. |
| C．It has to be held every other year. | D．It may take place on different dates. |

9 . Ants know when an earthquake is about to strike, researchers have discovered. Their behavior changes significantly prior to the quake and they resume normal functioning only a day after it. Gabriele Berberich of the University Duisburg-Essen in Germany presented these findings on Thursday at the European Geosciences Union annual meeting in Vienna according to LiveScience.
Berberich and her colleagues discovered that red wood ants preferred to build their colonies right along active faults in Germany. They counted 15,000 mounds （土堆)）lining the faults. These faults are the places where the earth violently bursts in earthquakes.
Using a special camera that tracked changes in activity. Berberich and her colleagues tracked the ants round the clock for three years, 2016 to 2019. They found that the ants' behavior changed only when the quake was over magnitude （级数）2. There were 10 earthquakes between magnitude 2.0 and 3.2 during this period, and many smaller ones. Humans can also sense quakes of over magnitude 2 only.
According to Berberich, normal ant activity consists of going about collecting food etc,during the day and resting in the night But before an earthquake, the ants didn't go back to their mound in the night and moved around outside it. This strange and abnormal behavior continued till a day after the earthquake, Berberich told a news conference, according to Livescience.
How do ants know an earthquake is coming? Berberich suggested that they could either be picking up changing gas emissions or noting tiny changes in the Earth's magnetic fields （磁场）. "Red wood ants have special cells which can detect changes in carbon dioxide levels. They also have special cells for detecting electromagnetic fields." she said. Berberich and her colleagues are planning to continue the research in areas where there are more and bigger earthquakes

10 . For several decades, there has been an extensive and organized campaign intended to generate distrust in science, funded by those whose interests and ideologies are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things.
Stressing successes isn’t wrong, but for many people it’s not persuasive. An alternative answer to the question “Why trust science?” is that scientists use the so-called scientific method. If you’ve got a high school science textbook lying around, you’ll probably find that answer in it. But what is typically thought to be the scientific method — develop a hypothesis (假设), then design an experiment to test it — isn’t what scientists actually do. Science is dynamic: new methods get invented; old ones get abandoned; and sometimes, scientists can be found doing many different things.
If there is no identifiable scientific method, then what is the reason for trust in science? The answer is how those claims are evaluated. The common element in modern science, regardless of the specific field or the particular methods being used, is the strict scrutiny (审查) of claims. It’s this tough, sustained process that works to make sure faulty claims are rejected. A scientific claim is never accepted as true until it has gone through a lengthy “peer review” because the reviewers are experts in the same field who have both the right and the obligation (责任) to find faults.
A key aspect of scientific judgment is that it is done collectively. No claim gets accepted until it has been vetted by dozens, if not hundreds, of heads. In areas that have been contested, like climate science and vaccine safety, it’s thousands. This is why we are generally justified in not worrying too much if a single scientist, even a very famous one, disagrees with the claim. And this is why diversity in science — the more people looking at a claim from different angles — is important.
Does this process ever go wrong? Of course. Scientists are humans. There is always the possibility of revising a claim on the basis of new evidence. Some people argue that we should not trust science because scientists are “always changing their minds.” While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that it explains what might otherwise appear paradoxical (矛盾的): that science produces both novelty and stability. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.
