1 . Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks, the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice.With no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.
1. What can we infer from the passage?| A．People have known the importance of animal protection a long time ago. |
| B．The number of hawks is on the decrease. |
| C．Animals play an important role in people’s life. |
| D．Many countries passed laws forbidding the killing of any animal. |
| A．Became more. | B．Became less. |
| C．Turned black. | D．Ate food. |
2 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.
Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.
In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.
The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.
The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.
So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.

3 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”
The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.
He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”
Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”

4 . Avi Loeb, a scientist, believes that we are not alone in the universe. The belief fits with Loeb’s alien (外星的) spaceship theory that at least one alien spaceship might be flying over the orbit (轨道) of Jupiter, which won the international attention last year.
Astronomers in Hawaii found the first known interstellar (星际的) object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away, part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris (碎片) from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door.”
“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.
Loeb says that “Oumuamua’s” behavior, means it can’t be a block of rock shaped like a long photo. He thinks it's more likely an object that’s very long and thin, perhaps like a long pancake or a ship’s sail. Loeb says that if someone shows him evidence that contradicts his beliefs, he will immediately give in.
Loeb believes himself a truth-teller and risk- taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn’t mind giving up all the titles he had and returning to the Israeli farming village where he grew up.

5 . Being trapped in an elevator(电梯) can be one of the worst experiences of one’s life. Some people who have such experiences may be afraid to use elevator again. In fact, there are some useful tips to follow when people are in trouble with the elevator.
First, take deep breaths and keep calm. Too much fear will add to your panic(恐慌) and make you too nervous to think clearly. Tell yourself to be patient and believe that nothing is impossible.
Secondly, use the emergency(急救) call inside the elevator or your mobile phone to let people outside know your are stuck in the elevator. There is an emergency call on the wall of each elevator. You may use your mobile phone to give light and find it. The phone number can be found around it.
Thirdly, putting on messages on Wechat(微信) is also a good idea to allow more people to find you are in need of help. If help hasn’t come, knock the door hard to get attention from other people in the building.
Fourthly, move less and try to relax. Even if the workers have known your situation, it may take them a long time to repair the elevator and bring you back to safety. Instead of keeping moving all the time, you are advised to keep still and relax yourself as much as possible, or you will make yourself tired out. Make sure that you are fine when the door is open.

6 . One of the most traditional British holidays is the “seaside holiday”. Typically, families get on a train or into a car and travel to British seaside towns. They sunbathe on the beach, buy ice creams, eat fish and chips, build sandcastles and so on.
In the early 1970s, air travel became affordable for the average family in the UK, and more and more British people started travelling abroad for their summer holidays. After all, the British weather isn't very good, even in summer, so a lot leave the UK for a vacation. Particularly popular with families on a budget is the “package holiday", where the cost of flights and accommodation are offered at a discounted price by travel agents.
In the 1980s and 1990s, young people in the UK became more wealthy, or at least had more disposable income. As a result, young people started to go abroad in groups, to places such as Spain and Greece. Once at their destination, they socialized with other groups of young people and had one long party.
British holidaying habits have begun to change, however. Climate change means that the UK now has a warmer climate than before, so people don't always feel they need to go overseas to find good weather. Also, the world seems a less certain place as interconnected economics rise and fall, which means that the cost of foreign holidays is less predictable than it used to be. As a result, more and more Britons are choosing to spend their summer holidays in the UK.
In the UK, the domestic (国内的) tourism industry---when people go on holiday in their own country---is healthier than it has been in decades. There is now an increased appreciation among Britons for the diversity of the UK. It is not just the geography and the diversity of climate-based activities on offer. It is also the diversity of the cultures in the UK that is beginning to be of interest to domestic tourists
The UK has always been famous for its international explorers, but now it is starting to discover itself.
1. What mainly caused Britons to travel abroad for holidays in the early 1970s?| A．The lower cost of flights. |

| D．Available for use. |
| A．Steady interconnected economics encourage more Britons to holiday in the UK. |
| B．Climate change has an impact on the change of British holidaying habits. |
| C．Package holiday was particularly popular with rich families in the early 1970s. |
| D．Both domestic and international tourists are interested in the diversity of the UK. |

7 . My work started in 2003 at my local animal shelter’s Adoption Department. It seems like such a long time ago. In the 13 years that have passed, more than 50,000 animals have passed the doors of the shelter. Most of them, I do not remember. But occasionally there are animals who stand out. Tabby was one such animal.
Tabby was one of the many homeless dogs. What’s more, she was blind and deaf. Tabby’s chances at adoption seemed remote at best. But one day a woman named Loretta came to the shelter. Her son, Gary, who suffered from epilepsy (癫痫) had seen Tabby’s picture on the shelter’s website. They were interested in meeting her! Most boys would want a puppy, a dog who could grow with him and run through grassy fields on summer days. Tabby would never be able to do that. But as they say, "love is blind". After meeting her, they decided to adopt Tabby!
If Tabby’s story had simply ended with her successful adoption, it would still have been something very special indeed but it was what happened after her adoption that some might label as "magical" or perhaps even miraculous. As Gary and Tabby did everything together, they became so "in tune" with one another that Tabby began to telegraph Gary’s seizures (疾病发作) before they occurred, giving his family a warning that one was about to strike. What’s more, Gary seemed to be having fewer and fewer seizures since Tabby’s arrival.
How could it be? There are some things that happen in this world that challenge all logic and understanding. Sometimes, the best that we can do is to accept a miraculous thing, which we didn’t attempt to explain. Because when you try to explain it, you lose the beauty and wonder of it all.
1. Which sentence can be used to describe Tabby?| A．She was so lovely that she could be easily adopted. |
| B．She suffered a lot from the disease-epilepsy. |
| C．She was so strong that she could run very fast. |
| D．She was homeless and couldn’t see or hear. |
| A．Amazing. | B．Typical. | C．Interesting. | D．Special. |
| A．Gary learnt about Tabby from a magazine. |
| B．Gary was cured in the company of Tabby. |
| C．Tabby could indicate a seizure before it struck. |
| D．Most boys would have the same decision as Gary. |
| A．Love is Blind: a Miraculous Dog | B．Give Me Food: My Dear Master |
| C．Love is Everywhere: a Poor Dog | D．Take Me Home: My Dear Boy |
8 . "True friendship is like sound health. The value of it is seldom known until it is lost," Charles Caleb Colton said. Just like in any other relationship, arguments and fights are also part of friendship. You will hardly find friends who have never fought with one another. Whatever the reason is, if a person feels that he is responsible for causing the differences, it is important that he should apologize to his friend.
Though you can use the email, text messages or chat for expressing your apology, the good old way of saying sorry to your friend through a letter will surely have a great effect on him. This will make your friend realize that your efforts of saying sorry are genuine and that you really care about him.
Points to Remember:
Timing: Write the letter at the proper time. It is not advisable to put it off for too long.
Words: While you are writing the letter, what matters most is that you truly feel sorry.
Sequence: Always begin by apologizing and saying sorry for your mistake. Then explain to him your side of the story. In the third and last paragraph, talk about what his friendship means to you and make a promise of not repeating the mistake.
Delivery: You should either post the letter or deliver it personally or through someone else. You can also keep it at a location where your friend will be able to find it easily.
Some people may try to point out the friend's mistake while writing the letter. Avoid this completely, as it can make matters worse. The letter has to be brief and should only talk about the subject that has led to your apology. Keep patient and do not expect immediate results. In some cases, it may take time for the person to forgive and forget.
1. What is the author's purpose of mentioning the saying in the first paragraph?| A．To let readers study the famous saying. |

| C．open | D．careful |
| A．Sending an email. | B．Sending text messages. |
| C．Chatting online. | D．Writing a letter. |
| A．Try to point out the friend's mistake. |
| B．Make the letter long and interesting. |
| C．Begin by apologizing and saying sorry for your mistake. |
| D．Write the importance of your friendship in the first paragraph. |
9 . Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
Professor Simard form University of British Columbia explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. As far as Simard is concerned, actually the opposite is true: trees survive through their co-operation, passing around necessary nutrition “depending on who needs it”.
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how moribund trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn’t take any notice of it” Simard says sadly. “Trees move nutrition into the young trees before they die, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
1. Which statement would Simard agree with?| A．Trees support each other. |
| B．Trees compete for nutrition. |
| C．Trees depend on their needs. |
| D．Trees co-operate with the fittest. |
| A．To explain the importance of fungi networks. |
| B．To introduce the function of neurons networks. |
| C．To illustrate how Nitrogen and carbon are shared. |
| D．To show how the forest ecological system works. |
| A．Energetic. | B．Ancient. | C．Previous | D．Dying |
| A．Protect tree societies. |
| B．Cut down oldest trees. |
| C．Get nutrition from nature. |
| D．Improve our environment. |
10 . When you think of the Himalayas, you may picture tall, rocky, snow-covered peaks. But that’s not true.
The subnival (亚冰雪的) region is the zone between the treeline and the snowline. It is 5 to 5 times as large as the areas of glaciers and permanent snow, which means studying it is vital to understanding the Himalayas as a whole.
The treeline is the edge of an ecosystem where trees are able to grow, and beyond the treeline environmental conditions become too tough to allow tree growth. Meanwhile, snowlines are the boundaries on mountains that separate areas with permanent snow (where snow is present for the majority of the year) from areas with seasonal or no snow.
Researchers used satellite data from 1993 to 2018 to measure plant cover between 4,150 meters and 6,000 meters above sea level. The scientists discovered that the greatest increase in plant cover was between an altitude of 5,000 meters and 5,500 meters. Subnival plants mostly include small shrubs and grasses.
Even areas once completely occupied by glaciers now hold rocks covered with mosses, lichen, and sometimes even flowers. In addition, the snowline seems to be retreating, while the treeline is expanding. This shows that the region is becoming warmer, causing more melting of snow and allowing vegetation to move up in height.
In the past 40 years, 25% of all Himalayan ice has been lost due to global warming. Himalayan glaciers are reducing by about 0.5 meters each year. The rate of glacier melting has doubled in this decade. The melting of glaciers increases water in the region, making it wetter. Receding snow also forces the snowline to move up, providing a greater amount of area for the warm and moist conditions, which are perfect for vegetation growth.
As of now, we do not know whether vegetation will accelerate or slow down the rate of glacier melting.
