A
You may have heard the saying “The Yangtze River is China’s mother river.” It’s almost 6,400 kilometers long. As the world’s third-longest river, it covers one-fifth of China’s land area. The Yangtze River Economic Zone(长江经济带) covers eleven provinces and municipalities, making up about forty percent of China’s total population and GDP.
On December 26, China passed the Yangtze River Protection Law, which came into force on March 1, 2021. It is the first law to protect a waterway in China.
The mother river is in great need of protection because something is wrong with it. For example, because of overfishing and water pollution, the river’s Chinese paddlefish has died out there. There’s also decertified land and soil pollution near the river.
According to the law, fishing will not be allowed in all of the Yangtze’s natural waterways, including its major tributaries(支流) and lakes. Those who are caught fishing will be fined(罚款) 50,000 to 500,000 yuan.
Digging sand will be strictly limited(限制) in the river. Many companies are digging sand along the river. However, this has led to lower water levels on the river, which has caused the river’s water to decline.
Companies and factories along the river will need to focus on green development. If their activities do harm to the waterways, they will be moved away, the law says.
21. What does the first paragraph tell us about the Yangtze River
A. How old it is. B. Why it’s important. C. What problems it has. D. Where it joins the sea.
22. What do we know about the Yangtze River Protection Law
A. It was passed on March 1, 2021. B. it came into force about ten years ago.
C. it has increased the population of the area.
D. It’s the first law to protect a waterway in China.
23. What does Paragraph 3 explain
A. Why the river needs protection. B. How the river is being polluted.
C. When Chinese paddlefish died out. D. How the river will be protected.
24. What does the underlined word “decline” in Paragraph 5 mean
A. Disappear. B. Become worse. C. Be hard to test. D. Be easy to control.
25. According to the passage, which is true about protecting the river
A. People can’t fish in the river’s major tributaries.
B. Digging sand will not be allowed in the river anymore.
C. Companies along the river will be moved to other places.
D. Anyone who causes pollution will be fined at least 50,000 yuan.

There are many deserts(沙漠) on the earth. And the following are some facts you may find interesting.
What are deserts like
Deserts can be hot and dry places. Rain may not fall there for months or years. Some deserts are sandy and stony(多石的). Deserts can also be very windy places. The wind can change the shape of the deserts. It moves sand around from place to place.
Temperatures in the desert can vary enormously(非常). During the daytime, the temperature may reach 40℃ even in the shade(阴凉处). At night deserts can become very cold. In winter there may even be a frost(霜冻) in the early morning.
Living in the desert
The camel is sometimes called “the ship of the desert”. It stores food in its hump(驼峰) and can go for days without water. It has large feet which help it not to fall into the soft sand. Its long eyelashes(睫毛) keep out the sand during sandstorms.
An oasis is an area of the desert where water may be found. The water may be in pools or under the ground. People and animals visit an oasis for water and food. Plants grow at an oasis. Some farmers are able to grow crops here.
The Arabian Desert
The Arabian Desert lies between the Red Sea and the Arabian Gulf. In some parts of the desert, it is too hot for people to live. Oil was discovered under parts of the desert and in the Arabian Gulf.

Ⅳ.任务型阅读(每小题2分，共10分)
根据短文内容完成短文后的任务。
The world is getting warmer. Human activity is the main reason for this, the United Nations(UN) said. For example, people use fossil fuels(化石燃料) like coal and oil. They give off a lot of greenhouse gases(温室气体) (especially CO2) into the air. This warms the earth.
As a result, many animals are dying out, (A) ______ as penguins(企鹅) and polar bears. It will soon make a difference to us as well. (D)Sea level will rise and many cities along the sea will disappear.
To fight climate change, countries around the world need to work together. China is now taking the lead. It has set new goals to deal (B) ______ this problem. It will bring its total greenhouse gas emissions(排放) to a peak(峰值) before 2030. (C)It will also achieve carbon neutrality(碳中和) before 2060, Xinhua reported.
Being carbon neutral means taking away the same amount of CO2 from the air as you put into it. It was set as an initiative(倡议) by the UN in 2015.
There are two ways to get to carbon neutrality. One is to plant more trees to absorb(吸收) the emitted(排放的) CO2. The other is to stop CO2 emissions altogether by using non-fossil(非化石) fuels. Examples of these fuels include electricity and wind energy.
Over 20 countries and regions have carbon neutrality goals. Most of them will plant more trees. So will China. If China can realize its goal, it will lower global(全球的) warming by around 0.2℃ to 0.3℃ alone, according to Climate Action Tracker(气候行动追踪组织).

Huge Waves Destroying Arctic Ice Faster than Expected
Ice covers much of the Arctic Ocean. Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves in the arctic waters.
The waves were discovered by accident in May, 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.
The ship travelled east and stopped next to a large block of ice around 50 miles from the small island of Hopen. Marchenko prepared to lead his students out onto the ice.
“We were ready to go but when I went out, I discovered many cracks around,” he remembers.
He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces.
Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship’s navigation system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists had never imagined that the process could happen so fast. The waves in these areas used to be small.
The speed and force of the huge waves there makes it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears that depend on sea ice to live is also in danger.
Some scientists think people will soon see even bigger waves in icy waters. As waves break up ice, seas will be more open, and waves will be stronger. There are stormy times ahead.
根据短文内容，请用完整句子回答下列问题。
46. When did Marchenko and his students discover huge waves in the arctic waters
___________________________________
47. What happened to the ice around the ship when the ship moved into the ice
___________________________________

Dear schoolmates,
Elephants are the largest mammals on land. They can live as long as 80 years. However, these days the number of elephants is becoming much smaller. Because people cut down forests they are losing their homes. Also, people kill them for their ivory. Elephants are in great danger. I think we should try our best to protect them. First, we should help make rules to stop people from killing elephants. Second, we shouldn’t cut down trees. Third, we shouldn’t buy anything made of ivory.
I believe everyone’s contribution(贡献) can make a big difference.
