英语目的状语常见表示法六种(课堂PPT)

1、1,英语目的状语表示法六种,一、用“so that+从句或so as to十不定式”表示。目的状语从句由so that引出时,从句谓语通常有情态动词can/could, will/would, may/might, should等。若主、从句主语相同,so that从句也可简化为so as to do sth的形式,通常置于句末,其否定式为so as not to do sth(注:不能用not so as to do sth, so not as to do sth或so as to not do sth)。如,2,He studies hard so that he can pass th

2、e exam. =He studies hard so as to pass the exam.他努力学习以便能通过考试。 I came in quietly so that I should not to wake him. =I came in quietly so as not to wake him. 我轻轻进来,以免吵醒他。,3,二、用“in order that+从句或in order to+不定式”表示。 此句式与上面的情况基本相同。若主、从句主语一致,in order that从句也可简化为in order(not)to do sth的形式,可置于句首或句末(注:否定式不能用n

3、ot in order to Do sth, in not order to do sth或in order to not do sth)。如,4,He does so in order that he wont be caught. =He does so in order not to be caught. 他那样做是为了不被抓住。 注:用in order (not)to do sth和 so as(not)to do sth表示目的时,有时可进一步简化为不定式的形式,但语气稍弱。如: He is saving to（so as to, in order to ）buy a car.他在存

4、钱,以便买车,5,对于So that和in order that引导的目的状语从句,若其主语与主句主语不同而用不定式改写,可用介词for来引出不定式的逻辑主语。如: I stood aside so that she might Pass. =I stood aside for her to pass. 我站在一边,让她过去。,6,三、用“for fear(that)十从句”表示。For fear的意思是“惟恐”、“以免”。从句谓语既可用、should/might+动词原形”这样的虚拟语气,也可用陈述语气。若主、从句主语相同,该句式可简化为,for fear of+名词或动名词”的形式。如:,

5、7,She doesnt let her child go out alone for fear(that) he is lost. 她不让孩子一个人出去,惟恐丢失。 The police man dared not fire for fear that he should hit for fear of hitting the others. 警察不敢开枪,怕击中别人。,8,四、用“in case+从句”表示。In case意为“以防”,与for fear that相似,in case所引导的从句也可用陈述语气或“should+动词原形”这样的虚拟语气。如: Take an umbrella

6、 in case it rains it should rain.带把雨伞,以防下雨。 注:“in case+从句”有时可简化为“in case of+名词”。如: The wall was built a long the river in case of floods.沿河建了这堵墙以防涨洪水。,9,五、用for+名词或动名词”表示。如: Let us go out for walk我们出去散散步吧。 This is a case for keeping records in.这是放唱片的盒子。 注:要表示“做某事为了达到做另一事之目的”, 英语通常用do sth to do sth,习惯

7、上不用do sth for doing sth。如: 他来这儿看足球赛。 正:He came here to see the football match. 误:He came here for seeing the football match.,10,六、用固定短语表示。 这类短语常见的有 for the purpose of (为了的目的) for the sake of(为了), for the good(benefit) of(为了的利益), in the hope of(怀着的期望), in praise of(称赞，歌), in honour of(为向表示敬意;为了纪念) , in search of(寻，寻求)，等等。,11,He came here for the purpose of giving us a talk.他来这儿是为了给我们作报告。 The teacher repeated part of his lecture for the good of those who had been absent. 为了缺课的学生,老师又把上次讲稿中的部分内容重讲了一遍。 They went out in search of food. 他们外出寻找食物。 I went there
