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 clothesB.to collect waste paper and soft drink cansC.to use both sides of paperD.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.B.Take a cloth bag when you go shopping.C.Dont use plastic bags.D.If your chair is broken, you can repair it.( )5.Which is the best title for this passage?A.A 4Rs ruleB.Protect the environmentC.Save energyD.Good habits13Unit 2 Topic 3 Section D 教师寄语：Never lose hope!一学习目标：1. 熟记本节单词及短语.2.复习并列句的用法。二学习重难点：复习并列句。三自主探究：（一）. 在文中找到并划出下面的短语1.从。中提取_2.制氧气_3.面临许多困难_4.植树者_5.不同类型的树_6即使_7.加油_8停止做某事_9.停下去做某事_（二） 自我检测题：单项选择。 ( )1.Its a long story, but you can hardly find new words in it.Good! _ it will be too hard for children.A.SoB.AndC.ButD.Or( )2.Students ought _ the truth.A.to tellB.tellC.tellingD.told( )3.He is tall, _ his son is short.A.whenB.orC.whileD.and( )4.If we travel a short distance, we should walk _ taking a bus.
