三、阅读理解
Thirty years ago, Lake Ponkapog in Hartwell was full of life. Many birds and animals lived beside the water which was full of fish. Now there are few birds, animals and fish. People polluted the lake water.
How did this happen First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.
Now there are many homes around the lake. People often use chemicals in their gardens. They also use chemicals inside their houses for cleaning or killing insects. There are many factories. Factories use chemicals to produce products and some chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from homes, factories, cars and trucks and then carries them into the lake. They pollute the water and kill the animals.
Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas from boats often leak(泄漏) into the lake. So more harmful chemicals go into the water in this way.
People in Hartwell are worried. They love their lake and want to save it. Will it be possible A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground. And they mustn’t use motorboats any more on the lake. All these may change people’s life. Only then Lake Ponkapog can be a beautiful, clean lake again.

One day, Paula Ma was walking along Castle Island’s beach. She found there were lots of plastic（塑料）pieces in the sea and some were too small to pick up. She began to think about how to solve the problem.
First, she did a survey. The result showed there were already 150 million tons of plastic in the sea, and every year there would be another 8 million tons. She realized something must be done. So she decided to invent a robot that could work under water. She tried again and again. At last her ROV came out. It could move through water and pick up plastic pieces, especially the small ones.
With this ROV, Paula Ma took part in the Broadcom Masters competition. It was one of the top STEM competitions. It’s for young students around the world. This year, more than 5,000 students were interested in the competition, but only a few got the chance. Paula Ma’s ROV caught a lot of attention. It had a camera with three different kinds of lights. It could find plastic pieces easily. Dana Yoerger, an expert, said, “The ROV is nicely done for a 12-year-old girl. It’s very clever.”
In fact, Paula Ma is always learning to solve the world problems and her parents are always supporting her. At the age of five, she began to go to workshops to learn engineering skills. When she was asked about the future plan, she said, “I want to be an engineer because I like building things. I think many world problems can be solved with new inventions. Right now, I’m just caring about plastic problems because there is still a long way to go.”

C．The competition is well organized. D．Some young girls are very clever.
29．Paula Ma wanted to be an engineer because she wanted to ________.

Here at Nature Loving Kids, we know how much you want to make a positive difference to our world! So read on to find out how to protect our earth.
Save energy and water! ▲On a fine and clear day, hang things outside to dry.

Be friendly to wildlife! ▲Make your garden wildlife friendly. You could build a bee hotel, or even create a pool. ▲If you own a cat that goes outdoors, put a bell around its neck so that vulnerable (弱小的) wildlife can hear it coming and make their escape (逃跑)!
Be an advocate (倡导者)! Share your knowledge with others, and help them become eco-heroes, too. It takes lots of people working together to make changes happen. So share, share, share! Reduce, reuse, recycle! Before you throw something away, stop and think about what else it could be used for.

Wetlands—lakes, rivers, marshes and coasts, can maintain biodiversity(保护生物多样性), control floods and remove pollutants. They are also helpful to rice and fish production, transportation and so on. They are important and necessary feeding and breeding grounds for migratory birds. They are the most threatened ecosystem(受到威胁的生态系统).
World Wetlands Day came from the Convention on Wetlands(湿地公约) signed in Iran, China joined the convention on July 31, 1992. By the end of 2019, our country had 57 wetland nature reserves listed as major wetlands for protection under the convention, covering a total of nearly 7 million hectares. ______________________, as China has wetlands with 65.9 million hectares, 10 percent of the world’s wetland areas, which comes fourth in the world. China also has some of Asia’s most important wetlands, such as Poyang Lake and Asia’s longest river, Yangtze River.
However, a WWF research showed China’s wetlands were seriously threatened by degradation because of pollution, climate change and over-exploitation. So our government has been taking actions to return farmland to wetland and remove some fish farms.
It was reported the 57 key Chinese wetlands increased by 2,479 hectares from 2018 to 2019. Li Yan, an official from the National Forestry and Grassland Administration, said at a news conference, “The area of wetlands in China has become larger over the past five years, growing by 202,600 hectares and making a great contribution to water quality and environmental protection. Between 2016 and 2020, China created 201 national wetland parks. China had 899 national wetland parks by the end of 2020, and nearly half of the country’s wetlands are protected by some level of government.”
China is carrying through on the convention for a continuous development and will make continuing efforts to perfect the laws on wetland protection. Several major projects on wetland protection will be carried out in some major areas, such as Yangtze River and the Beijing-Tianjin-Hebei province cluster.
36．Which of the following is the most suitable for the blank(空格) in Paragraph 2

80．例文：
Dear Headmaster,
Recently, I have become worried about the environment of the school dining hall.
Some people seem to treat it as if it were a rubbish area. They throw the leftover food about, on the table or on the ground. This makes the hall look unpleasant for us to come and eat there.
I have several solutions. First, get more people to form good habits by putting posters around the hall, asking them to be more thoughtful of their behaviors and protect our environment. Second, make people pick up their own litter. We can do this by asking some students to walk around the hall and watch out for those that drop litter. We can make those who are found dropping litter stay behind and tidy up the hall after all the students have finished their meal. I hope you find my ideas useful.
All in all, I do hope we can have a better dining hall, so that the students and the teachers can enjoy their lunch every day.
Yours sincerely,
Wang Peng
