　　含对比观点的议论文的写作 ◆技巧点拨 出现在高考 “读写任务”中含对比观点的议论文一般由三部分构成:观点1、观点2和“我”的看法。考生答题时，首先写出阅读材料的摘要，再按要求写议论文。议论文部分可按下列模板进行写作。 写作模板一：In fact,people have different opinions about _________（主题）.Some people think ____________(观点A)while_____________(观点B).Those who hold the first opinion think that _________（支持观点A的理由一）.What is more,_______(理由二). Moreover

　　,___________(理由三).In contrast,those who hold the second view think that____________ （支持观点B的理由一）.What is more,_____________(理二).Moreover,_____________(理由三). From my point of view,I think_____________(我的观点)./As to me,I agree with the former opinion.__________(陈述自己的理由，一般有两个理由)。写作模板二：

　　The topic of _____________（主题）is becoming more and more popular recently.There are two sides of opinions about it.Some people say A is _____________(观点A).They hold their view for the reason of _____________（支持A的理由一）.What is more,_____________(理二).Moreover,_____________(理由三). While others think that B is a better choice in the following three reasons.Firstly,_____________(支持B的理由一).Secondly(Besides),_____________（理由二）.Thirdly (Finally), _____________(理由三).

　　From where I stand,I think _____________(我的观点）. The reason is that _____________(原因).As a matter of fact,there are some other reasons to explain my choice. For me,the former is surely a wise choice. ◆活学活用 阅读下面的短文，然后按照要求写一篇150词左右的英语短文。 When students first go to a library,they may be at a loss as to what to read of all the different subjects.Well,Bacon tells you to “look at weak places in your armor(盔甲)”,and shows you how to fill up the blanks in your knowledge.On the other hand,it is no good just trying to fill your mind with knowledge.Knowledge in itself is often useless.A mind filled with too much knowledge is like a room too full of furniture;a man cannot walk about freely in it,or look out of the windows.It is much better to concentrate on a few subjects which interest you and to deal lightly with the others than to march heavily through the whole range(范围)of learning,like a silly tourist going through a museum and not missing a single object.If you try to master every subject you may become very wise,but you will be very lonely and you will probably lose all your friends.So you must learn to pick and choose,and you must also learn to look here and there in a library like a camel eating grass on the grass land.If you watch it eating,you will see that although he is supposed to be one of the most stupid animals in the world,he has at least one of the qualities( 品质)of the cultured(有修养的)man,the power to pick and choose.A student looking for mental food in a library should take the camel as his model. 写作内容 1．以约30个词概括短文要点； 2．然后以约120个词就“读书是否应有所选择还是应博览群书”的主题发表看法，并包括以下要点： (1)有人认为一个人的时间和精力有限，所以读书要有选择。 (2)有人认为要全面了解世界，就应当博览群书。 (3)你自己的看法及理由。 写作要求 1．可以使用实例或其他论述方法支持你的论点，也可以参照阅读材料的内容，但不得直接引用原文中的句子； 2．标题自定。 ____________________________________________________________________________________________________________________________________________________________________  Read Selectively or Intensively The passage gives us good advice that since it is impossible for one to read all kinds of books,we must learn to pick and choose the materials we read. In fact,people have different opinions about reading.Some people think we should read selectively while others think that we should read extensively.Those who hold the first opinion think that ones time and energy are limited and one can never read as many books as he wishes.In contrast,those who hold the second view think that to know the world from all perspectives one should absorb a variety of knowledge by reading extensively. As to me,I agree with the former opinion.Admittedly,we can absorb knowledge by reading extensively,but it doesn，t follow that we should read without discrimination.As our time and energy are limited,we should devote our limited time and energy to reading relevant and beneficial books.It，s a waste of time to read irrelevant books. Furthermore,some books are harmful to one，s mind.If we dont read books selectively,we will be misled by harmful books. 祝 您 高考总复习·人教版·英语 选修 8 Unit 2

Moreover, the parents will have a great impact on the Senior 3 students if they show too much concern by offering them tonics,which is bound to bring more stress to the Senior 3 students.They will feel cast down and ashamed when they can，t get a high mark as their parents have expected.Besides,they don，t think their efforts will pay off only if they take tonics. However, some students opinion completely differs from it.They are in favor of the opinion that it is easy for the Senior 3 students to feel tired by working hard,and tonics can help to bring themselves back to energy as soon as possible,so it is good to take some tonics.

　　(3)to differ with you on that(4)It won，t make much difference 2.What problems may arise when humans are cloned？(P10)克隆人会引发什么问题呢？ ◆词语辨析

　　arise;rise;raise;lift （1）arise 不及物动词，指“出现；发生；起立;上升”,是一种庄严的用语。 （2）rise 不及物动词,“上升，升高，耸起”之意，表示事物本身由低处移到高处,又引申为“起床，起立，发生，发源”等意义。 （3）raise 及物动词，“抬起，举起，升起” 表示把某物从低处抬到高处，有时指“提高价值、名誉、地位、工资” 等,又可作“抚养，饲养”解。 （4）lift 既用作不及物动词又可用作及物动词。“举起，抬起，升起，抬高”，强调用人力或机器把重物提高到较高的位置，比raise 的意味强，更具口语化。
