題目列表(包括答案和解析)

The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.

Water pollution

A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.

Air pollution

In big cities, factories, as well as cars, trucks and buses are the main cause of air pollution. Many people in cities now have serious health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is always covered by thick brown clouds.

Soil pollution

In order to have a good harvest, most of the farmers use chemicals too much in their fields. That’s bad for the soil. But this kind of pollution is difficult to stop.

Hope for the future

These problems are very serious for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Let’s be greener people!

Zhang Li lies in bed sadly. The 24-year-old young man lost his right leg because of a blood disease. The doctor said that his 10 years of smoking had caused the disease. “I began to smoke when I was in Junior 3. It made me feel like a man and I thought it looked cool. Now I know I was really wrong.” said Zhang.

It is a mistake many teenagers make. It is said that about 40 million of the country’s young people between 13 and 18 have tried smoking. Nearly 68 percent of teenager smokers smoked their first one before the age of 13. Those who live in big cities started even earlier. Many teenagers see people smoking in the movies. But in real life, stars like Jackie Chan think smoking is a bad thing. In fact, smoking is one of the top killers in China. Each year one million people die from smoking-related(與吸煙有關(guān)的)diseases. Smoking causes illnesses like lung cancer and heart disease.

Doctors say that the younger a person starts smoking, the worse it will be. If a person starts smoking as a teenager, he or she may live twenty-two years less than non-smokers.

1.What kind of disease did smoking cause for Zhang Li?

A. Lung cancer. B. Blood disease.   C. Heart disease.

2.From the passage, we know Zhang Li started to smoke when he was      years old.

A. 13   B. 14   C. 18

3.The city’s young people .

A. knew that smoking was a bad thing

B. tried smoking when they were in Junior 3

C. started smoking earlier than those in the country

A. Zhang Li had a disease and lost his left leg.

B. Smoking may cause many kinds of diseases.

C. Smoking may make you have a shorter life.

It’s important to learn about protecting our environment. Here is a 5R rule for us:
1.  Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste
2.  Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3.  Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(壓平)and melted (融化) and the melted things are made for new coke cans.
4.  Recover
When you buy a box of apples, there may be a few rotten(腐爛的)apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5.  Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society(社會(huì)). But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
【小題1】_______ can be recycled.
A.Only hard thingsB.Many thingsC.Few soft thingsD.All things
【小題2】The “recover” rule mainly requires us _______.
A.to throw waste things awayB.to cover waste things with earth
C.to get back the useful partsD.to throw the whole things away
【小題3】We can infer(推斷) that the writer of this passage may live in _______.
A.ChinaB.JapanC.AustraliaD.America
【小題4】Which of the following is true?
A.We will have no resources(資源) of nature unless we can do with the waste.
B.Recycling is the best way to save resources.
C.If we waste less, we can save more resources of nature.
D.More things are wasted in developed countries than in developing ones.
