Now people are trying to make the world a better place for birds to live in. People in China start the Bird Loving Week. Students from all parts of the country have been doing something to care for birds.
Meng Yiru, a 16 year old student from Nanyang Model High School in Shanghai, asked people to protect birds: Never put birds in cages. Go to visit them in the wild if you really love them. “I'll never forget the little sparrow(麻雀) I kept in a cage，” said Meng. “It stopped eating after I caught it and soon died.” Meng and her classmates put many of their ideas in their 300 word report to ask people to take better care of birds.
China is the home of more than 1，000 kinds of birds because the country is large and has almost every weather type to suit them.
But not everyone knows how to take good care of them. Some cut down trees and destroy the birds' homes. This has made the number of the birds go down quickly. A study shows that one out of eight birds, more than 1，200 kinds, in the world could die out. This includes 95 per cent of albatrosses(信天翁) and 60 per cent of cranes(鹤). Some birds you see every day, like pigeons and parrots, are also in danger!
To help them, people have set up 7，500 reserves which are suitable and safe for the birds. In China, there are big reserves like the ones near the Dongting Lake in Hunan and the Poyang Lake in Jiangxi. Is there anything that you can do for birds Take care of their homes. Feed them with something delicious. Well, think it over and begin to do it now!

Environmental protection is one of the hottest topics nowadays. It was also something that ancient Chinese paid great attention to. In fact, the world's earliest environmental protection idea, ministry(政府的部) and law were all born in China. How did the ancient Chinese protect the environment
The world's earliest idea of “managing state affairs(治国) through environmental protection”
Xunzi, a famous thinker in the Warring States Period, came up with the idea of “managing state affairs through environmental protection”. He wrote in his book that plants should be protected well by humans.
Guan Zhong, a government officer 400 years ahead of Xunzi, was also an environmental protection expert. He said “a king who cannot protect his plants is not doing a good job”．
________
Nine ministries set up by Shun, an ancient Chinese emperor, included “Yu”， an environmental protection ministry. The first “Yu” leader was Boyi, an environmental protection expert. He invented wells(井) so people could drink clean water. He knew a lot about animals and also called for animal protection.
The world's earliest “environmental protection law”
Over 4，000 years ago, Dayu, an ancient Chinese water control expert and also an emperor, made a rule, not allowing(允许) people to cut down trees in March or catch fish in June, because it was the time when they grew quickly.
Almost 3，000 years ago, Tianlu, the first environmental protection law, appeared in Qin. It recorded many ancient environmental protection rules. Two of them were interesting: firstly, make sure that rivers run smoothly; secondly, grass and trees should be burned to be fertilizer(肥料) only in summer. The second one is helpful even for today. It can help to keep air clean and fresh.
1 What is the purpose of first paragraph
A. To draw a conclusion(总结). B. To show an example.
C. To give the reasons. D. To introduce the topic.
2 Which of the following is the most suitable to be on the line “________”？

D. The world's earliest “animal protection leaders and experts”
3 Which of the following is NOT true according to the passage
A. The first environmental protection law appeared in Qin.
B. Plants shouldn't be burned in spring.
C. Boyi improved drinking water quality and asked people to protect animals.
D. Guan Zhong wrote in his book that vegetation should be protected well by humans.
4 Why didn't Dayu allow people to cut down trees in March or catch fish in June
A. Because people can only get wood and fish at the right time.
B. Because it was the time when they grew slowly.
C. Because they are against the law made by Dayu.
D. Because Dayu is a water control expert and also an emperor.

There are many wetlands in China and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home to many different kinds of animals. The world's largest Milu Deer Nature Reserve is there. More than 700 Milu deer live freely there. There are not many red crowned cranes in the world, but every winter you can see some in the Red crowned Crane Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor(既不……也不……) too low. There is a lot of rain and sunshine too. They are really good places for wildlife. Offering food and home to some special kinds of animals is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent floods(洪水). But some people want to change the wetlands to make more space for farms and less space for wildlife.

(2025无锡梁溪期末)A food chain is a way to show the relationships(关系) among living things in nature. It shows the path(路径) the energy takes from the sun through producers and consumers to decomposers. Everything needs energy to live on.
A producer is a living thing that makes energy from the sun. It absorbs sunlight, turns it into energy and keeps it. A perfect example of a producer is a vegetable or fruit. These plants take in sunlight through their green leaves, produce energy, and keep it in the other parts of the plant, such as its fruit and flowers—what is most useful to consumers.
A consumer is a living thing in the food chain that eats producers or other consumers for energy. These consumers can be insects, animals and humans. Insects, like grasshoppers(蚱蜢), eat producers and take in their energy. Consumers can also eat other consumers. For example, consumers like lions and tigers often eat other animals below them in the food chain. In this way, energy can be passed to other consumers.
A decomposer is a living thing in the food chain that gets its energy from both consumers and producers by eating dead plants and animals. Ants and some other insects are good examples of decomposers. These living things eat dead plants and animals, take in the energy to live on and put new energy into the earth. Plants use the energy to make energy of their own to start the cycle again.
The food chain includes all living things on the earth and is difficult to understand. We can make an easy picture of the food chain by choosing just one group of living things. Here is an example of a simple(简单的) food chain：
1 Which of the following living things may be a decomposer
A. Butterflies. B. Bamboos. C. Cranes. D. Ants.
2 What does the underlined word “absorbs” mean in Paragraph 2
A. Makes. B. Catches. C. Eats. D. Saves.
3 Which of the following pictures shows how the food chain works
A. B.
C. D.

(2024南通启东期末)The traditional Chinese lunar calendar divides the year into the 24 Solar Terms. In China, people created the 24 Solar Terms thousands of years ago to guide agricultural(农业的) production.
Rain Water is one of the 24 Solar Terms which stands for the increase(增加) in rainfall and rise in temperature. With its arrival, the ice on the river melts, wild geese fly from south to north, and trees and grass turn green again.
Here are several things you may not know but can make you know about Rain Water better. Let me introduce them to you.
Rain in spring is as precious(宝贵的) as oil
According to an old Chinese saying, the rainfall in spring is as precious as oil. In northern China the spring drought(旱灾) is common. And the rain of this season is only 10 to 15 per cent of yearly average rainfall. So at that time, rain is so precious and important to the crops.
Return of a cold period
A returning cold in spring often happens during Rain Water. The fast increase in air humidity(湿度) can result in lower temperature and wet weather. Remember not to take off your coats so early in this period.
Visit to in laws(姻亲)
One of the main customs during Rain Water is sons in law visiting their in laws and giving gifts. According to the tradition, gifts are usually two cane chairs with four metres of red belt. They stand for good health and long life. Another traditional gift is a pot of cooked pig's knuckles(蹄). The son in law expresses his thankfulness this way.
Nutritious porridge(营养粥)
The wet weather during Rain Water is harmful to people's health according to Chinese medical practice. So a bowl of nutritious porridge is the best choice to keep the body alive and healthy.

But look at what we've done. We've polluted the air and water. We've cut down trees, and it makes the world become warm. We even kill wild animals for food. As a result, some wild animals have died out.
We must take action. Start with simple steps like turning off taps to save water. We shall take an active part in protecting wild animals. Also, we need to plant more trees to make the world greener. Let's protect nature together.
Thank_you!

Dear Mr Principal，
I have found some information about South Hill. It is 5 kilometres south of Sunny Street. It is about 900 metres high and is the only hill in Sunshine Town. It is also the only hill close to Moonlight Town and Starlight Town. We can walk from Sunny Street to South Hill. It is not a difficult walk for teenagers—it just takes about 2 hours.
On the way, we can enjoy the beautiful view of the country. It is a good place for the charity walk because of the open space and fresh air. There is a large amount of flat land. The grass is green and the flowers are colourful in spring.
I hope you will find the information useful.
Yours，
Amy
听第二篇短文，回答第16～20小题。
It is Saturday today. I took part in the “Environment Protector” activity with my classmates today. In the morning, we went to the People's Park at 8：00 by bus. When we got there, we found that some children were climbing the trees. The ground and public walls were very dirty. So we began to pick up the rubbish and clean the public walls. We also planted some trees. All of us worked very hard. We think it's our duty to take good care of our environment. If everyone protects the environment, the world will become more and more beautiful.

One possible version:
The_Earth_Is_Our_Home
The_earth_is_our_home_and_we_only_have_one_earth.
However, our earth is in danger now. People cut down too many trees to make space for buildings and farmlands. This leads to less and less space for wild animals. What's worse, people kill them for their fur, bones and some other parts of the body. In addition, more and more natural disasters happen around the world every year. As a result, many people and animals lose their lives in the disasters.
It's time for us to save the earth now. First, the government should make laws to stop these people. Second, we shouldn't buy fur coats any more. Last, we should live a green life to save energy. In these ways, we believe our earth will be better.
