六、阅读理解。
Many large cities are not so beautiful. There is a lot of trash in the streets. In the trash, however, there is still something that can be useful.
If people want to solve the problem of waste, there is no time to be lost. They must work out ways of making use of good things which are just thrown away as waste.
When a car gets too old, it may not run any more. But the metal that the car is made of is still good. It can be put to use again. When a bottle is empty, it goes out in the trash. But bottle glass can be ground（碾碎） into sand and used to pave（铺） streets. Garbage from food can be changed into fertilizer（肥料）. But first you have to fish out all the glass and metal.
Garbage can also be a good source for making building blocks. Now, more and more machines are designed for this purpose（目的）. Some day, people will watch films in a magnificent cinema which has been built out of garbage. Future buildings, roads, and cities may be made from garbage. But so far, building beautiful cities out of garbage is only a dream.

beautiful.

______________________________________________________________
When we are at home, we should turn off the tap while brushing our teeth. We should also take showers for less than 10 minutes to save water. When we go to school, we’d better walk, ride bikes or take the public transport instead of going by car. At school, we can use both sides of the paper and remember to turn off the lights whenwe leave the classroom. We can collect our used exercise books for recycling.
I’m sure if everyone does something for the environment, we can make the earth a better place to live.
