2011高考英语二轮复习 in order to与so as to等用法详析教案VIP专享

in order to 与 so as to 等用 法详析 让我们先来看一下本单元的几个句子: In order to survive, Chuck develops a friendship with an unusual friend-a volleyball he calls Wilson. 为了求生,查克交了一个不同寻常的朋友-- 一个被他叫作威尔逊的排球。... who is always so busy that he has little time for his friends. 他总是很忙,以至于几乎没有时间交朋友。 这两句中,in order to +动词原形引导目的状语。so as to +动词原形,to+动词 原 形 都 可 以 引 导 目 的 状 语 。 有 时 为 了 表 示 强 调 , 也 可 以 将 in order to do, to do 等放在句首,而 so as to do 一般不放在句首,也比较口语化。表达否定的目的时,可以用 in order not to do 和 so as not to do 这两种结构。例: In order to (=To) hear more clearly, we moved to the front row. 为了听得更清楚,我们挪到了前排。 He ran quickly in order not to (= so as not to) be late for the meeting. 他跑得很快,以便(为的是)不迟到。 so +adj. / adv. that 可以引导结果状语从句,意思是"如此……以至于……",也可用于 so + adj. + n.+that 结构。例: He ran so fast that nobody could catch up with him. 他跑得太快,没人能追得上他。 He drank so much Coke that he felt terrible. 他喝了那么多可乐,感觉很难受。 so that 和 in order that 可以引导的目的状语从句与结果状语从句,引导目的状语从句时说明主语的行为目的,引导结果状语从句 时多 说明主句行为的结果。从结构上看前者多带有情态动词。请对比下列从句: I'll keep the box in the shade so that the sun doesn't burn the little plants. 我把箱子放在树荫下,这样太阳就烤不坏植物。(结果状语从句) They stayed in Hangzhou so that they could visit the West Lake. 他们在杭州停留下来以便可以游览一下西湖。(目的状语从句)
