According to the wildlife trade monitoring organization—TRAFFIC， about one million pangolins （穿山甲） were killed from 2000 through 2013， mainly for their scales （鱗片）， which are used in medicine. Pangolins are sensitive creatures and picky eaters that only eat certain kinds of ants， a diet thats very difficult to copy in the food chain.

“In the last decade， theres been a huge growth trade in pangolins between continents， especially their scales，” says Dan Challender， chair of the pangolin specialist group. Previously， most pangolin killing happened within Asia， he says. This change means that Asian pangolins are becoming difficult to find but that the value of the scales makes it worth the extra cost to take pangolins from Africa to Asia secretly.

All eight types of pangolins， four in Africa and four in Asia， are in danger of extinction due to the illegal trade. International trade in the four types of Asian pangolins has been banned （禁止） since 2000. In the past few years， a ban on international commercial trade in all eight types has gone into effect. It was voted by 183 governments that are parties to the Convention on International Trade in Endangered Species （CITES）， which is in charge of cross-border trade in wild animals and their parts.

Pangolins are eaten as bushmeat in western and central Africa and by some local groups in South and Southeast Asia. Their parts also are used in Ghana， Nigeria， South Africa， and elsewhere in sub-Saharan Africa as traditional medicine. But they are now endangered. Perhaps no pangolins can be seen when our next generation grow up.

1. What can we learn about pangolins from Paragraph 1？

A. Their meat is very delicious. B. They are killed for their scales.

C. They eat all kinds of ants. D. They are at the top of the food chain.

2. Why are pangolins brought from Africa to Asia？

A. They are cheaper in Africa. B. No laws protect them in Africa.

C. People in Asia can really save them. D. They are rare in Asia now.

3. What does Paragraph 3 mainly tell us about pangolins？

A. They have many different types. B. The bans on their trade are worthwhile.

C. Governments have tried to protect them. D. People trade them in different ways.

4. Whats the authors attitude towards pangolins future？

A. Positive. B. Uncaring. C. Concerned. D. Confident.

You can help protect the planet！ Try some of the following tips and get green.

1 Set out cans and bottles for neighborhood pickup， or exchange them for cash at a recycling center. Choose rechargeable batteries （充電電池）， then recycle them when they die. 2 Sharing books is a great way to reduce waste and reuse materials.

Improve the outdoors. Plant a leafy tree that loses its leaves in fall on the south side of your home. Its shade will cool your house in the summer. 3 Trees also help clean the air we breathe. They produce oxygen and reduce carbon dioxide.

Dont litter. Rubbish thrown carelessly outside often washes into rivers， lakes and finally into the oceans. 4

Cut down on waste. If you have a dripping faucet （滴水的水龍頭） in the house， ask your parents to replace the washer inside it. If you stop a faucet from leaking one drop each second， you can save 2，700 gallons of water a year. Dont pile （堆放） food onto your plate. 5 Enough food to feed 49 million people ends up in landfills in the United States each year.

A. Recycle and reuse first.

B. Participate in clean-up days at a park.

C. Take only what you know youll really be able to eat.

Natural disasters often come unexpectedly， killed many people and destroying countless homes. But what on earth lead to natural disasters？ Of course， natural change plays an unique and important role. However， now people are aware of that we humans are partly responsible for them， which have done something harmful to the earth. We cut down too many trees in the forests so far. Better still， we have badly polluted the environment. Considering the great damages caused by us， we should take action as soon as possibly to protect our environment. Besides， we must keep calm and try to save us and help others when disasters happen.

Michele Gentile， an Italian bookseller， is offering free books to children in exchange for plastic bottles to recycle. Michele owns Ex Libris Cafe in Polla， a small town in southern Italy. He said he thought of the recycling program， because he wanted to inspire children in the small town to read and pay attention to the environment.

‘‘My goal is to spread the passion and love for books among those people in Italy who do not usually read while at the time helping the environment，” Gentile explained. The idea for the initiative （倡議） came after Gentile cooperated with a nearby middle school on an aluminum recycling project. Working together， the schoolchildren and Gentile collected enough cans to purchase books for an entire class. His new program took off from there and has already spread into northern Italy. Gentile hopes his work will continue to make headlines and become a worldwide initiative.

The free books come from customers in Gentiles shop who have donated money to buy a ‘‘suspended” book. The idea comes from a World War Ⅱ practice in which customers would buy two coffees： one for themselves and another for the next person in line. Gentile has been using the extra books as part of his recycling initiative. While Gentiles program is a great way to recycle waste and get kids to read， it also brings awareness to the growing problem of plastic waste. Single-use plastics make up around 26 percent of all the plastics in the world， only 14 percent of which are recycled. Plastics that end up in landfills take around 500 years to decompose （分解）， which is a major concern for environmentalists.

Cutting down on plastic waste is important if we want to better the environment for future generations， and recycling programs like Gentiles book giveaway are a great way to meet that goal.

1. What is the purpose of Gentiles book program？

A. To sell books. B. To attract customers.

C. To collect money. D. To inspire reading and recycling.

2. Gentile came up with the idea of the program after.

A. working with a school to recycle cans B. seeing school kids dont like reading

C. donating books to a local school D. buying a “suspended” book for a child

3. Who pays for the books of the project？

A. The local government. B. Gentile himself.

C. Some publishers. D. His customers.

4. What is the best title for the text？

A. An Italians Reading Initiative B. Recycling Cans Gets Kids Free Books

C. Gentiles Way of Doing Business D. A New Way to Deal with Plastic Waste

About 20 years ago， some 15，000 red pandas wandered the treetops of the Himalaya forests in South Asia. But with a large number of people entering their living places， these shy and solitary （獨處的） creatures cant meet each other and reproduce. Now the population has fallen by more than 50 percent.

To save the red pandas here， Lama and his research team need to know which parts of the forests the remaining pandas are living in. Thats where the tracking devices come in. “Mapping the path they travel will let us know which areas of the forest need to be reforested to connect the most red pandas to one another，” Lama says.

Because red pandas can be hard to spot and catch， no one had ever used GPS collars （頸圈） to study them in the wild. But Lama and his team had a great plan. They first would make sure the animals would be comfortable wearing the collars. So， they tested the collars on two red pandas in a local zoo. “We persuade them to let us measure their necks and fit them with the collars by letting them choose a reward—grapes， apples， or bananas，” Lama says.

Then came the next challenge： catching red pandas. Once they spotted a red panda， a team of vets set up a tall， fence-like tarp （油布） around the base of the tree with a box trap （陷阱） at the bottom. That way when the red panda climbed down the tree surrounded by the tarp， it had no choice but to enter the trap. It was then quickly controlled， collared and released.

From September to December 2019， the team trapped 10 red pandas—six females and four males. Their collars recorded their location every two hours and sent the information to researchers once a day. Over the next year， the team tracked the red pandas movements so that they identified where to plant new forests and helped red pandas meet more easily.

5. What has led to the reduction of red pandas in South Asia？

A. Their normal lives are badly influenced. B. They arent adapted to living in groups.

C. Their ability to reproduce is weakened. D. They try to avoid meeting each other.

6. Why did the research team track the movements of red pandas？

A. To study their living behavior. B. To protect them from hunters.

C. To know where to plant forests. D. To find if they can often meet.

7. How did the research team get red pandas to wear collars？

A. By offering them treats. B. By measuring their necks.

C. By setting tarps. D. By using traps.

8. What does the text mainly talk about？

A. The falling population of red pandas. B. The clever way to keep track of red pandas.

C. The research on red pandas reproduction. D. The way of building living places for red pandas.
