Chemicals in the smoke from power stations cause a lot of damage（损害；毁坏）. They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” gradually（逐渐地）destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the countrys trees had been damaged by the year 1986.Time and time again there are serious accidents that pollute the air. In 1986 there was a serious accident at a nuclear power station in Russia. A cloud of radiation flew across the whole Europe. It is said that 125,000 people died in Russia as a result of illness caused by this accident.In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal.

Heres a 4Rs rule for us.Reduce If you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people dont know what to do with waste in big cities, so its necessary to reduce waste.Reuse You should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you dont use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.Recycle Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where theyre smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.Repair If one of the legs of your table is broken, you can repair it. If you want to change for better ones, its better for you to sell the old ones or give them to other people who can use them after doing some repair.( )16.The “Reduce” rule mainly requires us _.A.to use things wiselyB.to cut down many treesC.to use paper carelesslyD.to use more and more things( )17.Whats the right order of recycling cola cans?a.smash them flatb.collect the used cansc.smelt themd.send them to a factoryA.a-b-c-dB.d-c-b-aC.b-d-a-cD.b-d-c-a( )18.The “Reuse” rule mainly requires us _.A.to throw away the old clothes B.to collect waste paper and soft drink cansC.to use both sides of paper D.to give the old but usable things to the poor( )19.Which sentence is about the “Repair” rule?A.When you leave a room, turn off the lights.B.Take a cloth bag when you go shopping.C.Dont use plastic bags.D.If your chair is broken, you can repair it.( )20.Which is the best title for this passage?A.A 4Rs rule B.Protect the environmentC.Save energy D.Good habits(E篇)What do people do with their old, out of date but still useful computers? Most people dont know how to deal with them. Many old computers are put away. Many more are simply thrown away as rubbish.Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products(产品). Dell, Hewlett Packard and other companies now also take back some old computers of their own brands.In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升级).Yet many people are throwing away good computers, while others cannot afford them at all.
