       I 布景介绍

　　依据多年来对雅思写作大作文的剖析研究，发现，虽然谈论文的论题繁复，但其问题形式都能够归属于两大类，评论和剖析处理，评论类常见的如：To what extent do you agree or disagree?What is your opinion?而剖析处理是指对某一负面现象进行原因的剖析，再给出处理办法。如：Discuss the possible causes of this phenomenon and suggest some recommendations about how to combat it.

　　上述两类相信参加国雅思考试或者在预备的烤鸭们都现已十分了解了，那么在考试中呈现几率较高的是第一类评论型的标题，占了百分之八十以上，所以学会此类标题的证明进程的扩展对谈论文分数的进步起关键作用。

　　在雅思写作的评分标准中，咱们看到前两个评分标准中，均呈现了对阶段扩展的描述，第一个评分标准task response，指使命完成度，在文章内容方面的表现即文章是否答复了标题的关于topic的证明，是否都围绕主题，无偏题离题现象发生，能否完好全面的对论题进行证明。而第二点coherence and cohesion，指连接和联接，内容是否连接，很大程度上取决与证明进程的扩展是否有严密关联，有无逻辑性。可见谈论问证明进程的合理有逻辑的扩展十分重要。

　　II 退让段的概念及用法

　　在谈论文中，常见的证明办法很多，如举比如、解说、类比、比照、列数据等，今日写作组的专家要给咱们总结介绍一类在证明中能否表现证明的全面性的办法，即退让的证明办法，首要咱们来看几个句型：1. As is granted, …However, convincing arguments have been made that …2.Opponents would argue that… However, …3. Although/ In spite of the fact that …， people tend to believe that …4. It is undeniable that …从以上三个句型，咱们看出退让就是先退一步供认自己不赞同的一个事实，再对其进行辩驳，如某人去面试，老板要回绝延聘选用这个职工，他会在回绝前先说一番供认这个人在某些方面还不错的一些话，这就是退让。这样证明的长处是愈加全面的证明，不会一味的一边倒，就片面的以为一个事情的存在只有长处或只有缺陷，且证明也更有说服力。这种证明办法常呈现在评论类的单边证明中，咱们来看一个标题：

　　The main purpose of public libraries is to provide books and they should not waste their limited resources and space on providing expensive hi-tech media such as computer software, videos and DVDs. To what extent do you agree or disagree?针对这样一个标题，经过审题，标题要求考生评论图书是否需求供给高科技媒体。依据剖析，咱们能够得出单边证明的结构，赞同供给多媒体。详细结构参照如下：

　　Introduction: State my opinion

　　The hi-tech media should been provided by the public libraries.

　　Body: Ph 1 Making concession

　　Multimedia facilities are expensive.

　　Ph2 Reason one to support my opinion.

　　Hi-tech media can store information much longer than traditional means.

　　Ph3 Reason two to support my opinion

　　Visiting a library with multimedia access is much more interesting.

　　Conclusion: Restate my opinion

　　The investment is justified and should be encouraged.

　　从上述结构咱们看出作者的观念是支持供给高科技媒体，但这个证明进程十分全面，它先在证明的第一代就退一步供认其缺陷，然后再就这一点进行辩驳，这个阶段就是退让段，参阅之前供给句型，得出这一段：Opponents of a high-tech library would argue that multimedia facilities are expensive. This may be true to some extent, because a DVD player is often more expensive than a bookshelf. However, with immense storage capacity, these new high-tech media can actually save the most valuable resource-space.

退让段还能够运用到评论类另一种结构中，笔者谓之双边倾向证明。咱们经过一个详细的实例来解说这种证明结构以及退让在其间的用法。

　　There are social, medical and technical problems associated with the use of mobile phones. What forms do they take? Do you agree that the problems outweigh the benefits of mobile phones?

　　的教师主张此题一定要仔细审题，由于这个问题形式对文章的结构有着直接的影响。它有两问，第一问要答复手机的三个方面的问题，第二问优缺陷评论，结合这两问，得出文章结构如下：

　　Introduction: State my opinion

　　The problems of mobile phones far exceed the merits.

　　Body: Ph 1 the benefits brought about by mobiles (Making concession)

　　Convenient, functional

　　Ph2 the social, medial and technical problems of mobile phones

　　Conclusion: Restate my opinion

　　Although mobile phones have some benefits, the negative influences should not be overlooked.

　　看完结构，不难理解双边倾向的结构即两个方面长处和缺陷都提及，作者的观念是倾向其间一方的，那么不赞同的那一方的证明段就能够理解为退让段。结合句式，咱们能够写一下退让段的topic sentence:It is undeniable that mobile phones have facilitated our lives in many different ways. 接着能够列举手机运用的几个详细的长处。这种退让和单边证明退让的区别是它能够不用直接在这个阶段后边辩驳。

　　III 结语

　　退让段在证明进程中有着相当广泛的实战含义，它能够协助考生扩展文章的字数，到达要求，此外，它还能使得证明进程愈加全面，期望为写作取得高分有实在的协助。
