What a great waste it is！ A suggestion has been put forward that we should recycle the textbooks. Some students in my group agree to this suggestion. For one thing， recycling textbooks can save a lot of natural resources， which are used to make textbooks. And it can alsosave plenty of family expenses. For another， in western countries， recycling textbooks is very popular and it gives us a good example. But some have different opinions about it， for the content of the textbooks are often renewed. Whats more， it is not proper to make notes in the textbooks. But in my opinion， this is a wonderful idea because this will do good to both the government and the families. .高频单词点击 用所给单词的正确形式填空 1.Flowers make no (differ) to this room. 答案：difference 2.Their answers are (exact) the same. 答案：exactly 3.He has had some (disturb) experience. 答案：disturbing 4.I have no (object) to your proposal. 答案：objection 5.The steady (accumulate) of small debts was a ball and chain to his progress. 答案：accumulation 6.The project was predicated on the (assume) that the economy was expanding. 答案：assumption 7.This (regular) refers only to children. 答案：regulation 8.She put some (decorate) on the Christmas tree. 答案：decorations 9.We accepted the agreement without (argue). 答案：argument 10.There has been a lot of (resist) to this new law. 答案：resistance 1. 得到好结果；取得成功；偿清 pay off 2. 沮丧，不愉快 cast down 4. 一定或注定做 be bound to do 3. 赞成，支持 in favor of 5. 使复生，使复活 bring back to life 6. 白费力气；枉费心机 in vain .重点短语回顾 7. 不时，偶尔 from time to time 8. 状况(情况)很好(坏) in good/poor condition .常用佳句必备 1.Then came the disturbing news that Dolly had become seriously ill. 答案：then came the thunder 信息提取 时间状语then放于句首，句子常用全部倒装。 例句仿写 起初十分寂静，然后传传来了雷声。 At first it was quiet， and . 2.On the other hand， Dollys appearance raised a storm of objections and had a great impact on the media and public imagination. 答案：On the other hand 信息提取 on the other hand“另一方面”。 例句仿写 另一方面，通过读这本书，你还会学到很多 知识。 ， you will also learn a lot through reading this book. 例句仿写 这一计划是以经济发展的设想为依据的.
