so...that和so that的用法区别

  • o…that…与so that的用法

    我们都知道so that引导目的状语从句,so…that…引导结果状语从句.它们有所不同,请注意下面几点:

    1、在so…that…句型中,so后面加形容词或副词,其意为“如此……以至于……”.如:

    1) This book is so interesting that everyone wants to read it.

    这本书很有趣,人人都想看看.

    2) He ran so fast that I couldn’t catch up with him.他跑得那么快,我没赶上他.

    2、so… that…引导的是表示结果的状语从句,但不一定是“如此……以至于……”.如:

    1) The workers did so well that he was pleased with them.工人们干得很好,他对他们很满意.

    2) I was so busy here (that) I had no time to write a letter.

    我在这里很忙,没时间写信.

    3、so that引导目的状语从句,其从句中的谓语动词通常和can,may,

    should等情态动词连用,而且主句和从句之间不使用逗号,意为“以便,为了,使能够”.如:

    1) They got up early so that they could catch the early bus.

    为了能赶上早班车,他们早早就起床了.

    2) Say slowly so that I can understand you.说慢点,好让我听明白.

    4、so

    that句型也可以用来引导结果状语从句,意为“因此,结果”,这时其从句中的谓语动词不与情态动词连用.这种结构和so…that…引导的结果在含义上有很大的区别.

    So that句型所表示的结果往往同主句有因果关系,而so…that…句型所表示的结果往往表明so后面形容词或副词和程度.请比较:

    He didn’t plan his time well,so that he didn’t finish his work in time.

    他没有把时间计划好,结果没有按时完成这项工作.

    (没按时完成这项工作的原因是没计划好时间)

    It’s so hot that I can’t sleep.天气热得我不能入睡.

    (天气热到人不能入睡的程度.)
