2 . Every day as the sun rises, Ma Hongyi, a 66-year-old farmer, can be seen patrolling (巡逻) Yuncheng Salt Lake with his dog in Yuncheng city, North China’s Shanxi province.

Ma still remembers the day when he first saw two big pink birds wandering through the water. “I had never seen such pretty birds. They were even taller than me, with long wings,” Ma recalls. He was later informed that those birds were flamingos, a rare sight in China, which were listed on the International Union for Protection of Nature’s red list of endangered species in 2013. From that day on, Ma started his second career as a volunteer to prevent human beings from doing harm to the wildlife. “The birds are attracted by the good environment,” Ma says. “I will do my best to protect the lake so that birds can come here every year.”

Yuncheng Salt Lake covers an area of 132 square kilometers and used to serve as a salt production base. As the country began attaching greater importance to environmental protection, an ecological (生态的) protection and development center was set up in 2012 to carry out regular ecological protection and restoration of the lake. “The greatest value of the Salt Lake lies in its ecology, which should be properly protected,” says Chu Xianghao, head of the city. The lake area hosts 292 types of wild animals, along with 782 plant varieties, some of which are newly recorded species in the country.

After patrolling the lake as a volunteer for over four years, Ma was employed by the local government to help with wildlife protection in 2019. “The lake’s ecology is getting better,” Ma says, adding that he looks forward to the arrival of the flamingos every year. “Some of them are my old friends,” he says.

4 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.

Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.

A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.

He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”

In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.

“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.

The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.

1. How many wild pandas are there in China?

A．About 260.	B．About 635.
C．About 2,635.	D．About 2,000.

2. What does Liu Jianguo mean in Paragraph 4?

A．China needs more help from the World Wildlife Fund.

B．It is difficult to control the temperature rise within 3.5℃.

C．Bamboo is sensitive to the changes of temperature.

D．China is making great efforts to protect the pandas.

3. What can we learn from the first paragraph?

A．The Qinling Mountains can provide enough bamboo for the pandas.

B．Pandas in the Qinling Mountains are only threatened by the loss of food.

C．Lots of the bamboo in the Qinling Mountains will probably disappear.

D．Pandas have already eaten 99% of the bamboo in the Qinling Mountains.

4. Which can be the best title for the text?

A．The Disappearance of Bamboo

B．Necessity to Change Pandas’ Food

C．A New Threat Faced by the Pandas

5 . Conservation scientist Kim Williams-Guillen was trying her best to come up with a way to save endangered sea turtles (海龟) from egg thieves when she had an “aha” moment: If she placed a fake (假的) egg containing a GPS tracker in the reptiles’ nests, she might be able to track the thieves.

Williams-Guillen found a flexible plastic material to mimic (仿造) the shell of real eggs. She and colleagues then used a 3D printer to produce the fakes of the same size, weight, and texture and put the smallest GPS tracking devices inside each. The researchers then went to four Costa Rican beaches, where green sea turtle come ashore to make their nests. As mothers laid their eggs under cover of night, the researchers slipped a fake egg into each nest. Once the fakes are covered in sand and mix with the real eggs, it’s very difficult to tell the difference between the two.

Of the 101 fake eggs, 25 were taken by thieves. The farthest moving egg traveled 137 kilometers inland. The fake egg sent its final signal the next day from a residential property, suggesting that the research team had tracked the eggs through “all of the players in the entire chain.”

By understanding that chain, Williams-Guillen says researchers can identify trading hot spots. She emphasizes that the tracker is not a way to catch local thieves, many of them living in poverty, but a tool to better understand their routes, which could help them and eventually law enforcement (执法部门) identify larger players in the chain.

In the meantime, Williams-Guillen and her colleagues are working to get their fake eggs to other sea turtle conservation organizations. Ultimately, though, scientists and nonprofits are going to engage communities with local outreach and education programs to save sea turtles. She says, “The real meat and potatoes of conservation isn’t going to come from deploying (布署) eggs.”

3. What do Williams-Guillen’s words mean in the last paragraph?

A．Deploying eggs needs advocating further.

B．Turtle conservation mainly relies on joint efforts.

C．She feels disappointed with the local communities.

D．Deploying eggs makes no difference in preserving turtles.

4. Which of the following can be the best title of the text?

A．Saving endangered sea turtles is urgent

B．Endangered turtles can be traced with GPS

C．GPS eggs helps to save endangered sea turtles

D．A conservation scientist is devoted to protecting sea turtles

6 . More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise(天堂) for different kinds of groups of birds and have been called"Bird Islands".

Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.

To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.

Inspection(视察) officials and management employees often patrol（巡逻） the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous(食肉的) animals, as well as illegal hunters from breaking up the birds’nest building,egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.

B．tell the farmers there some knowledge about animal protection.

C．call on people to love and protect the bird.

D．all of the above.

8 . A young Dutch inventor is widening his effort to cleanup floating (浮动的) plastic from the Pacific Ocean. He has developed a floating device (设备) to trap plastic waste moving into rivers before it reaches the oceans.

Boyan Slat was just 18 years old when he invented a system for catching waste in the ocean. He also founded an environmental group called “The Ocean Cleanup”. Its purpose is to develop the system. Last year, Slat showed the next step: a floating device which is called Interceptor. It removes plastic out of rivers. The device is powered by energy from the sun. “The 1,000 rivers are responsible for about 80% of plastic going into the world’s oceans,” said Slat. Three of the machines have already been used. Each machine costs about $775, 660, but the cost might drop as production increases.

Since they were used, the machines have been doing very well, collecting the plastic bottles and all the rubbish in the rivers. According to Slat, it is necessary to close “the tap”, which means preventing more plastic from reaching the ocean in the first place. He wanted to clean them all in the next five years. “This is not going to be easy, but if we do get this done, we could truly make our oceans again, ”said Slat.

The device is designed to be safe in rivers. Its nose is shaped to change directions to keep it away from larger floating things. It works by guiding plastic waste into an opening in the front of the device. The waste is then carried inside the machine where it is dropped into containers. The devices ends a text message to local operators that can come and empty it when it is full.

1. What do we know about Interceptor?

A．It needs solar power to work.	B．It is mainly used in the oceans.
C．It is being under test.	D．It can help sort waste.

2. What does “the tap” refer to in Paragraph 3?

3. What’s the function of the device’s nose?

A．To ensure the device’s safety.	B．To send operators text messages.
C．To empty the waste.	D．To serve as containers.

4. Where is the text most likely from?

A．A novel.	B．A magazine.
C．A diary.	D．A guidebook.

9 . Will you crazy about these newly-built products that are not merely quite useful but also good to the environment? Come and see then!

Eco-friendly Umbrella

Traditional umbrellas come with a fixed surface. Although it is changeable, you cannot replace it easily. This eco-friendly design is more flexible. It is actually only an umbrella skeleton without any surface, which can be folded, so you can put anything such as newspapers, plastic bags or whatever you want to serve as the protecting surface.

Pollution-sensitive Dress

Don’t be caught outside unaware of pollution levels in the air. The pollution-sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly. This dress—which is actually quite pretty—looks like you pull it from the bottom of the dirty laundry pile when the air is dirty. It might protect your health by advising you to stay indoors for the day, but it won’t do you any favor if you’re meeting with clients.

Eco-friendly Car Racer

Can you image a car racer is so eco-friendly that its tyres are made from potatoes, its body is created from hemp (大麻) and rapeseed oil and it runs on fuel made from wheat and sugar beet? The one seater racing car called Eco One is built by experts from Warwick University, who hope that Eco One will be used by the automotive industry. It is sold at $ 51,000.

Eco-friendly Moss (苔藓) Carpet

Do you know it is said that walking on fresh grass can really increases your blood circulation? The Moss Carpet, created by Nguyen La Chanh, looks at getting the grass to your feet. The mat includes ball moss, island moss and forest moss. The humidity (湿度) of the bathroom ensures that it grows well. And that’s why you need to place it there and not anywhere else.

10 . The earth is dying before us, yet we sit and watch. If the TV or the game system breaks, we run off to the stores to get it fixed immediately no matter what the cost. Why aren’t we willing to fix our earth? Are our televisions and game systems more important to us than where we live? Where shall we continue to live, until the end of time?

The earth is our home and cannot be replaced. We must take care of it. We have come up with so much technology that limits us instead of helping us. Take that game system we run to repair. What does it do? It occupies kids’ time! The earth has already given kids plenty of entertainment in the forms of fields and hills, forests and plains, water and land. However, instead of using what the earth has given us, and helping kids by giving them exercise as they run around, we decide to ruin kids’ minds with game systems that glue them to the screen for hours, and make them ignore their homework and chores. We have polluted this earth by making these things which do not even help in any way!

We have already messed up this world, we have ruined the air, water, and animals that it has so willingly provided for us. We need to stop this destruction of life and bring back the world we had before. It will not be easy, but everybody can help! What about something as simple as turning the lights off when you leave a room? Recycling what can be recycled? Picking up litter? Donating money to an environmental organization? None of these things are very hard. We can’t just always say, “Oh, the earth is a mess. Ah, well, those big companies that are polluting so much can stop and fix it.” Instead, we need to help out. It’s not only those big companies; it’s everyday things that we do too that are ruining the earth. So, stop and think about what you can do to make a difference to our world!
