More than 30,000 drivers and front seat passengers are killed or seriously injured each year. At the speed of only 30 miles per hour, it is the same as falling from a third-floor window. Wearing a seat belt(安全带) saves lives; it reduces your chance of death or serious injury by more than half in traffic accidents.
So drivers or front seat passengers over 14 years old in most vehicles(车辆) must wear a seat belt. If you do not, you could be fined(罚金) up to £50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver’s duty to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.
However, you do not have to wear a seat belt if you are reversing your vehicle(倒车); or if you are a postman using a special vehicle; or if you have a valid medical certificate which allows you not to wear it. Make sure about all the above before you decide not to wear your seat belt. Remember you may be taken to the police station for not doing so.

A.a medical magazine B.a police report

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.

Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.

How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.

But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won’t be used up.

A. use the water with salt in it           B. remove the salt from sea water

C. get water from underground              D. reuse the water in cities
