英语中，我们可以用to，in order to或so that来表示目 的。区别是:to，in order to和以前学过的so as to引导的是目的状语短语，构成简单句。例如:
He got up early to/in order to/so as to catch the first bus.
To/In order to get back his ball， the boy said sorry to the old man for breaking his window.
【注意】so as to不能置于句首。
so that引导目的状语从句，构成复合句，并且从句中谓语动词常与can(could)，may(might)等情态动词连用。例如:
He got up early so that he could catch the first bus.
They are studying hard so that they will/may pass the final examination.
to，in order to，so as to和so that引导的目的状语，在下列情况中替换如下:
1)主、从句主语一致。例如:
He listened carefully so that he could follow the teacher. →He listened carefully to follow the teacher.
2)主、从句主语不一致。例如:
He stopped so that the students could write down the words on the blackboard→He stopped for the students to write down the words on the blackboard.
3) so that也可以引导表示结果的状语从句，意思是“因此”。例如:
It was too cold，so that we couldn t work.天太冷了，因此我们无法工作。
He often tells stories that are not true，so that nobody
believes him.他常常编造故事，因此没人相信他。

C. turned me over D. turned over me
【解析】 答案为A。
本题考查knock down和turn over的区别。knock down 为“撞倒”，turn over为“翻转”;人称代词作他们的宾语要放在中间，所以选A。
例3 单项填空
Shortly after we ， a waiter came over to our ta ble with a smile.

C. sat ourselves D. took place
【解析】 答案为B。
seat为及物动词，该接宾语或用被动式;sit为不及物动词，不能接宾语;take place为“发生”，不合语境。take ones place才表示“就位”。所以选B。
