关于目的状语。具体解析。 谢谢老师
解题思路: 如下
解题过程:
目的状语
一. 不定式表目的(作目的状语)“为了…”
㈠ to do sth, in order to do sth, so as to do sth,
So/such...as to do sth(否定形式为在不定式前+not即not+to do sth)
Eg: 1)He bought a bicycle to go to town more quickly.
2)To get the best results, use clean water.
3)He ran so fast as to catch the first bus.
4)Let’s hurry so not to be late for school.
注意
(1) so as to位于句中; in order to位于句中;句首
Eg: 1)They started early in order to/so as to get there in time.
2)In order to get there in time, they started early.
(2) 不定式作状语,主句的主语即为不定式的逻辑主语
Eg: He worked hard in order to catch up with the top student in the class.
如果不是句子的主语,用for引出
Eg: Mom opened the door for Jane to come in.
㈡ so that(句中)/in order that(句中,句首)引导的目的状语从句,从句中常含有情态动词,can/could may/might…译为“以便,目的是为了…”
Eg: He got up early so that/in order that he might catch the first bus.
注意:当so that/in order that从句的主语与主句的主语一致时,可为so as to/in order to。
最终答案:略
