People usually check whether their keys, wallets and phones are with them before going out. But many people in China now have one more important thing to take, a face mask. They hope that it can protect them from polluted air.

Since January, many cities in China have seen a lot of hazy (薄雾蒙蒙的) days. In Beijing, only five days in January were free of smog. People in Xi'an only saw a blue sky on one day in February. Smog is dirty air that looks like fog and smoke.

Poor air is bad for people's health, especially for children and the elderly. A report from Beijing Children's Hospital shows that from Jan. 5 to 11, half of the patients in the internal medicine department are there for respiratory problems.

Air problems have become more and more serious for the whole nation. Premier Wen Jiabao made his last government work report on March 5. The report said that the government should work hard to arrest pollution and give people a healthy living environment. It calls on people to make full use of energy and resources and cut down on energy use.“We should give people hope through our actions,” Wen said. 64. What does Paragraph 3 mainly talk about? A. The ways to fight air pollution.

B. The health problems that air pollution brings about. C. The reasons for people to get ill in January. D. The ways to keep healthy.

65. What does the underlined word “ arrest” mean?

A. Improve. B. Reduce. C. Stop. D. Increase. 66. What can we learn from WenJiabao's report?

A. The environment has improved a lot since Wen was in office. B. Many people feel disappointed with the air pollution problem.

C. The government will try its best to solve the air pollution problem. D. The air pollution problem in Beijing has been solved. 67. What does the author write the passage mainly for?

A. To show us how to make use of energy and resources. B. To call on people to protect our environment. C. To tell us not to live in Beijing and Xi'an now. D. To ask us to support our government all the time.

Bags of Love

Last year, I worked in a middle school near my mother's house, and I stayed with her for a month. During that time, I helped her do some housework and buy some food. After the first week, I noticed that the food was eaten up very quickly. Then I began keeping an eye on my mum. To my surprise, I found that she would put some of the food into a paper bag and go out with it at about nine every morning. And finally, I decided to follow her. I saw her taking the food to the street children. She would also spend a lot of time talking and playing with them.

One day, I talked to a neighbor and found out that my mum was well-known in the area. The children were very friendly with her and even thought of her as their own mother. Then it hit me---why wouldn't she want to tell me about it? Was she worried about that I would stop buying food if I found out?

When my mum got home, I gave her a big hug. I told her she didn't need to keep it a secret from me. And she told me something about the children. Some of them lived with an old lady in a small house. Others slept on the street. For years, she was helping the poor street children by giving them food. After she told me everything , I was so moved by how selfless she was. She helped others in need. As her son, I was so proud of my mum. I continued to buy food for my mum after that. But I always added one more bag for her other children.

To understand why the Earth is warming up, first of all, we need to understand why it is warm. Our planet is covered with atmosphere(大气).Sunlight passes through the atmosphere and reaches the Earth. The Sun heats up the Earth's surface. When the heat rises into the air, it is stopped by some special gases in the atmosphere like CO2, the heat returns to the Earth and keeps it warm.

Power stations and cars release(释放)so many green-house gases every day. So we can help stop global warming by using less electric things such as turning off lights

when we leave a room, asking our parents to turn down the heating in our house to save energy. We can also stop global warming by finding other ways of transportation. For example, ride a bicycle or walk instead of going by car. Another way to help stop global warming is to plant and care for trees. Because trees take in C02 , they are our best friends when fighting against global warming.

The problem of global warming cannot be solved in a day. It may take a long time to find clean energy, such as wind energy. It may take a long time to plant the trees again which were cut down. But every little thing each person can do to save energy and our forests will
