1、module 3 unit 3 重难点解析（语法)语法归纳精讲 在上一模块中我们学习了表示时间的状语从句，那么如果要表达的是一个行为的目的、原因或结果又该怎么办呢？首先我们来看一下本模块中出现的几个句子：i like fu mingxia because she was the first woman to win twice at the olympics of 1996我喜欢伏明霞，因为她是第一个在1996年奥运会获得两块金牌的女运动员。he also wrote books so that doctors could learn about new treatments他也写书，以便医生

2、们可以学到新的治疗方式。there were few doctors,so he had to work very hard。医生很少,所以他要十分努力地工作。 从汉语译文中可以看出,第一个句子中有一个原因状语从句,第二句中包含一个目的状语从句，而第三句包含结果状语从句。那么，原因、目的和结果状语从句有什么特点而又该怎么使用呢？1原因状语从句 在句中作原因状语的从句称为原因状语从句。原因状语从句可置于句 首,也可置于句尾。引导原因状语从句的常用词可分为两类：单词引导 词和短语引导词。单词引导词主要有because，as，since等,短语引导词 主要有now that，for the reas

3、on that，in that，seeing that等. because，as，since的用法： 这三个词都有“因为”之意，但用法和具体内涵各异。 （1)because语气最强，用以回答why引起的提问，可表示已知或未知的 事实.它可和强调词only，merely，just及否定词not连用，所引导的 从句常位于主句之后,只有强调时才置于主句之前。它还可用于强调结构. e.g. he was absent from school because he was ill他病了,没上学。 it was because i wanted to see my uncle that i went to

4、 town yesterday. 昨天我是因为想去看我叔叔才进城的. (2）as语气最弱，较口语化，所表达的原因比较明显，或是已知的事实，故不需要强调。as从句多置于主句之前。 e.g.as he was，in a hurry，he left his bag home由于他太匆忙才把包丢在家里了。 （3）since的语气也较弱，常表对方已知的事实,往往相当于汉语的“既然”.它和as一样，其前亦不可用强调词和not，亦不可用于强调结构。e.g. since everyone makes mistakes, you shouldnt always criticize him既然每个人都犯错误，你不

5、应老是批评他.2目的状语从句 在句中作目的状语的从句称为目的状语从句。目的状语从句可置于句首、句中或句尾。 常用引导词或短语有：so，so that，in order that，for fear that，in case等。 so that，in order that的用法： in order that常用于正式文体，可置于句首,也可置于句尾，而so that只 置于句中,但也有置于句首的,so that短语中有时可省略that。 e.g。 i hurried through my work in order that i could be in time for wonderful tv p

6、rogrammes我匆匆完成我的工作以便能够赶上精彩的电视节目。 speak louder so(that）all the people in the hall can hear you 大声点讲，以便大厅里的人都能听清.3结果状语从句 在句中作结果状语的从句称为结果状语从句。结果状语从句一般置于句尾。其引导词或短语常见的有：that，so,so that，sothat，such that,suchthat等. (1)so that的用法 so that既可引导目的状语从句也可引导结果状语从句，在引导目的 状语从句时，从句中往往跟cancouldmaymightwillwouldshall s

7、hould等情态动词连用，而引导结果状语从句时类似的情态动词则很少出现。引导这两种状语从句时,有时其中的that可省略.e。g。 we arrived early in the morning，so（that)we caught the first train 我们早上到得很早，所以赶上了首列火车。 (2)sothat的用法 sothat一的常用句型有四种。口语中that经常省略。so+形容词+that e。g. the text was so boring(that)i gave up reading it half-way through这本书真没趣，我读到一半便放弃了。so+副词+tha

8、t e.g.he drove so carelessly that he almost lost his life他开车太粗心，差点丧了命。so manyfewmuchlittle+相应形式的名词+that e.g。 he got so little money that his family had to live on welfare money。 他工资很少，他的家人不得不靠救济金生活。so+动词+that e.g. it so happened that he didnt receive my invitation 真巧他没收到我的请帖。 (3）suchthat的用法 常用句型有四种，

9、口语中that经常省略。such+a+形容词+可数名词单数+that e.g. it was such a terrible day（that)none of us would find an excuse for going out to play天气太糟了，谁都没有找到理由出去玩了。such+形容词+可数名词复数+that e。g. they are such good children that we all love them 这些孩子如此好,我们都很喜欢。such+形容词+不可数名词+that e.g。 this was such fine music that it was wor
