    Air pollution influences our health in many ways. No air means death. Though we can't see it, there is air around us. Air is everywhere and it gives a life to every living things. But bad air makes people ill. In the city, there are a great many people and there are too many cars running on the road. The cars send out bad gases (气体). There are many factories too. From the chimneys (烟卤) of these factories, we get the smoke usually in black colour. Every day we breathe it in and out. This makes us feel sick. When people talk about air pollution, they are usually thinking about outdoor air pollution. But a lot of air pollution comes from indoor activities such as smoking and cooking. Indoor air pollution can hurt people's eyes, noses and throats. So air pollution, both indoor and outdoor, can also lead to lung cancer (肺癌) and heart disease.

    Everyone should help fight against pollution. In order to keep us healthy, we have to go out to the countryside to breathe more fresh air. Or we can climb up hills to get more fresh air.

根据短文内容，从方框内所给的选项中选出能填入空白处的最佳选项，使短文意思通顺。

    We should not use more water than we actually need. If we do, we will not have enough water in the future.It is not a difficult question to answer. If we remove more fresh water than nature replaces, we have taken too much.

    Many cities run campaigns (运动) to get people to stop wasting water. They show them ways they can cut back on water use.What's more, they carry out programs that offer money to reduce water use. For example, they give people shower heads and toilets that use less water.

    Another threat (威胁) to our water supply is pollution. When our sources of fresh water get polluted, we can no longer use this water. This also endangers (危及) the animals that depend on the water.

    We can save lots of water by not letting taps (水龙头) run while we brush our teeth or by turning off taps right after washing hands. By collecting cold water when we're taking warm showers, we can also save water.In this way, we can make full use of water.

A. However, just how much is too much? B. There are several things we can do to save water. C. Finally, they make laws to control the use of water. D. We don't have to let the cold water run until it gets warm. E. They also increase water bills for people who use too much.
