There was a small village near the mountain. There were a lot of trees in the mountain. People in the 1 always got something from it, such as animals and trees.  When they wanted to 2 a house, they cut down the trees. And they also killed the animals for 3 . Trees were very 4 in their daily life. They made tables, chairs 5   beds by cutting down the trees. In addition, when they 6 meals, they still used some trees for wood. However, they only cut down trees but 7planted new trees. So the trees were fewer and fewer; the animals were becoming 8 as well.

    One summer, it rained 9in the village. The rain lasted for about a week. The soil(土壤)and the stones on the mountain fell down and soon 10  the whole village. They finally knew they should not only cut down trees but also needed to protect them.

    Water is so important to people that we can't live without it. Water is the source of life. If there is not enough water, our life will be difficult to go on. For example, it has little rain in some places. Farmers there don't have enough water for growing rice and vegetables. So people in the city may not get enough food.

    There's much water on the Earth, but most of it is salty ocean water. In fact, most of the water in the world is not fit to drink. Groundwater is fresh and drinkable, but it is very easy to be polluted. At the same time, it is not easy to clean up dirty or salty water. So it is very important to save water. Here are the things we can do in our daily lives.

    Don't leave the water running when we brush our teeth.

    Take a shower instead of a bath, because taking a bath uses much more water than a shower—about twice as much. What's more, we can take shorter showers.

    We can clean the floor with the water used for washing vegetables.

    Electricity is an important part in our life. We can't see or touch it, but it is all around us. Our life will be terrible without electricity. But some people don't know that everyone should save electricity. When it is not completely dark, many street lamps (路灯) light up early in some streets. Some people don't turn off the lights when they leave the room. Some people are sleeping with the lights on. They are all wrong. Here I make some suggestions about stopping these things:

    *Turn on the street lamps on time. We light them from 7：00 p. m.～5：30 a. m. in summer, and from 5：30 p. m.~6：00 a. m. in winter.

    *If some small areas are very dark, just turn on a few lights.

    *The distance (距离) between street lights can be 50～60 meters. It can save electricity and money.

    *If there are some activities, such as fairs, we can make the lights bright；if there is no activity, lights needn't be too bright.

    Ask people to save electricity through TV shows, newspapers, and so on.

    Electricity is a valuable resource (资源). It helps us live well and conveniently. We should take action to save it at once!
