We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.Today in most large cities, fresh water is used only once, and then it runs to waste system. But it is possible to pipe the used water to a purifying （净化）factory. There it can be filtered （过滤） and treated with chemicals so that it can be used again, just as it were fresh from a spring.But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All wed have to do to make use of the seawater on earth is to get rid of the salt. This process is called desalinization（脱盐作用）, and it is already in use in many parts of the world.6.The way to stop wasting our limited water is to _.A.do experiments with waterB.purify the used water and reuse itC.use fresh water once againD.make use of seawater【批阅】回答正确！【答案】B7.The following tells us how to reuse the used water.

All transportation and every machine in the world depend on it. The wheel is the simplest yet perhaps the most remarkable（卓越）of all inventions, because there are no wheels in nature no living thing was ever created with wheels. How, then, did man come to invent the wheel? Perhaps some early hunters found that they could roll the carcass（屠宰后的畜体）of a heavy animal through the forest on logs（圆木）more easily than they could carry it. However, the logs themselves weighed a lot.It must have taken a great prehistoric（史前）thinker to imagine two thin slices of logs connected, at their centers by a string stick. This would roll along just as the logs did, yet be much lighter and easier to handle. Thus the wheel and axle（车轴）came into being and with them the first carts.11.The wheel is important because _.A.it was mans first real inventionB.all transportation depends on itC.every machine depends on itD.both B and C【批阅】回答正确！【答案】D12.The wheel is said to be _.
