Heres 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 dont know what to do with waste in big cities, so its 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 dont 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 theyre 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, its better for you to sell the old ones or give them to other people who can use them after doing some repair.( )1.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( )2.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( )3.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( )4.Which sentence is about the “Repair” rule?A.When you leave a room, turn off the lights.
