Many of the things we do every day can change the Earth’s temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases.
Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water.
The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals.
Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don’t do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world.

查看习题详情和答案>>It is not easy for people to sail (航海) around the world in quite small boats. Sometimes the weather gets bad. Accidents can happen easily and quickly.
One family once had an accident. A big fish swam under their boat and bit holes in it. Sea water came in and the boat soon went down. Luckily these people had another small boat——a lifeboat, so they all got into the lifeboat. They lived in the boat for many days. They ate and slept, and always hoped. At last people in a ship saved them.
How do people live in a very small lifeboat for a long time? They must be strong in every way, they must have a hope, and they must have a strong desire（愿望）to live. People cannot drink seawater. If they drink a lot of sea water, they will quickly die. They must catch rainwater and drink it. They must also catch fish and birds for food. Lifeboats do not often carry cookers. So people can not cook their food in the lifeboats. Raw (生的) fish and birds are not very nice but they are their only food. They must eat raw food, or they will die.
【小题1】When the boat sank (下沉), the lifeboat gave the people _______.
| A．food | B．beds | C．rainwater | D．hope |
| A．their boat met bad weather | B．their boat hit a big rock and it was broken |
| C．nobody knew how to sail | D．a fish bit holes in their boat |
A. fish and birds B rainwater
C. both sea water and rainwater D. both A and B
【小题4】From the article (文章) we can know that ______.
| A．It’s not interesting to sail around the world. |
| B．Fish in the sea are so dangerous. |
| C．we must have a strong desire（愿望）to live when we are in danger. |
| D．Nobody knows when we will die. |
