二、句型剖析
1.in order to等作目的状语
【典型例句】
In order to learn English well,he attended a summer course.
为了学好英语,他参加了夏季培训班。
He works hard in order to learn English well.
为了学好英语,他很用功。
They arrived earlier so as to finish the work on time.
为了按时完成工作他们早到了。
He left early in order that he would/could arrive on time.
他早早动身为的是按时到达。
We got here to help him.
我们来是帮他的忙。

in order to,so as to,so that,in order that
都可以作目的状语,但在用法上有差别:
①不定式作目的状语,不如in order to do sth.强烈,若把动词不定式的逻辑主语表示出来可构成in order for sb. to do sth.。
②so as to引导的短语也可作目的状语,但不位于主句句首,而in order to和to do sth.可放后主句句首及主句后。若不定式的逻辑主语与主句主语不一致,则改用so that或in order that从句。
③in order that与so that都表示"为了",引导目的状语从句,可通用,且从句中多常用情态动词。in order that从句中多用情态动词may,might,shall及should。
活学巧用
1.单项填空
(1)Helen listened carefully________she might discover exactly what John wanted.
A.so as that
B.in order that
C.in order to
D.so as to
答案:B
(2)The old man put on his glasses________ see better.
A.for the purpose B.in order that
C.so as D.in order to
提示:此处后面是短语而非句子,去掉B;for the purpose of+n./v.ing故排除A项;C项应为so as to。
答案:D
(3)John shut everyone out of the kitchen________ he could prepare his grand surprise for the party.
A.which B.when
C.so that D.as if
提示:句意为:"约翰把每个人从厨房里赶出来为了为晚会准备一个大大的惊喜。"shut everyone out of the kitchen的目的是"prepare...",so that可表目的。
