Here’s a 4Rs rule for us.ReduceIf 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 don’t know what to do with waste in big cities, so it’s necessary to reduce waste.ReuseYou should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don’t use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.RecycleBottles, 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 they’re smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.RepairIf one of the legs of your table is broken, you can repair it. If you want to change for better ones, it’s better for you to sell the old ones or give them to other people who can use them after doing some repair.( )36.The “Reduce” rule mainly requires us _____.A.to use things wisely B.to cut down many treesC.to use paper carelessly D.to use more and more things( )37.What’s the right order of recycling cola cans?a.smash them flat b.collect the used cansc.smelt them d.send them to a factoryA.a-b-c-d B.d-c-b-a C.b-d-a-c D.b-d-c-a( )38.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( )39.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.Don’t use plastic bags.D.If your chair is broken, you can repair it.( )40.Which is the best title for this passage?A.A 4Rs rule B.Protect the environment C.Save energy D.Good habits。
