  下面是CN人才网小编给大家推荐的英语语法目的状语从句用法,快来看看吧。

  目的状语从句的一个特点:由于目的都是未来的行为,所以从句中一般用表示未来可能性时态,当然还可以用will,would,can等等。

  1、由so...the...和 such...that...引导的目的状语从句,应该注意可能出现的以下结构,例如:

  I am telling you that lest you should make a mistake.

  我告诉你这一点,以免你搞错。

  so nice a boy that…

  such a nice boy that…

  so beautiful/diligent/carefully … that…

  such (fine weather/great improvement) that…

  2、so that引导的结果状语从句是我们在英语学习中经常见到的一个词组,例如:

  1)She worked hard so that everything would be ready by 5 o'clock.

  她努力工作,以便在五点前是一切都就绪。

  2)She looked down so that she should not see his eyes.

  她垂下目光,使她看不到他的眼睛。

  3)Everyone lend a hand, so that the sowing was done in time.

  3、so much so that的用法,该结构用于形容词或副词之后,表示"到如此程度以致于"。例如:

  He was very weak, so much so that he could not walk.

  I long to visit Beijing, so much so that I dream about it every night.

  4、in order(that)"以便" to the end that "为……起见,以便"例句:

  1)He works hard in order that his family may be happy.

  为了让家人幸福,他努力工作。

  2)He shouted at the top of his voice,to the that(=in order that)he might be heard.

  他高声呼喊,为的是让人们能听见他的说话。

  5、含有情态动词的目的状语从句,例句:

  1)I am punishing the child lest he should make the same mistake.

  我惩罚那个孩子,以免他再犯同样的错误。

  2)She took her umbrella lest it(should)rain.

  他带了把雨伞,唯恐天要下雨。

  3)Lest the wall(should)collapse,they evacuated the buliding.

  他们撤离了大楼,以防墙壁倒塌。

  6、in case既可引导目的状语从句,也可引导条件状语从句,主要视句意而定:

  1)In case he comes, let me know.

  如果他来,告诉我一声。

  2)Tell me in case you get into difficulty.

  遇到困难请告诉我。

  in case引导目的状语从句,从句有时可用“should+动词原形”这样的形式:

  Take your coat in case it rains (should rain). 带着雨衣以防下雨。
