高中教师教学参考:爱变脸的“so... that”
http://www.sina.com.cn 2005/01/07 12:56  英语辅导报

  “so...that...”句型的意思是“如此/这么……以致于……”,常引导结果状语从句,但“so...that...”是个爱“变脸”句型,你一不留意就会出错。“so...that...”句型及其转换也是中考的热点,现将其用法总结归纳如下,让我们一起来看看它是怎样变的吧。

  一、 so... that...句型中的so是副词,常常用来修饰形容词或副词,常用句型为:主语+谓语+so+adj. / adv. + that从句。例如:

  1. he is so young that she can't look after herself.

  2. The boy ran so fast that I couldn't catch him.

  3. He was so angry that he couldn't say a word.

  二、 在“such... that...”句型中,such修饰名词,意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时,句子中要用“so...that...”而不能用“such...that...”。例如:

  1. He has so much money that he can buy what he wanted.

  2. I've had so many falls that I have pains here and there.

  3. There is little water in the glass that I can't drink any more.

  三、 so与that也可连起来写,即变成:... so that ...(以便 / 为了……),引导目的状语从句。例如:

  1. I got up early so that I could catch the early bus.

  2. Please open the window so that we can breathe fresh air.

  3. You must go now so that you won't be late.

  四、以“so...that”引导的结果状语从句可以转换成不定式的简单句,即可转换为“...enough to...”或“...too...to”句型,但这种转换必须符合下列条件:

  1. 当主句和从句的主语一致,且that从句是肯定句时,可用“enough to do sth.”来转换。例如:

  The man is so strong that he can lift the heavy box.→

  The man is strong enough to lift the heavy box.

  He was so clever that he can understand what I siad. →

  He was clever enough to understand what I siad.

  2. 当主句和从句的主语不一致,且that从句是肯定句时,可以用“enough for sb. to do sth.”来替换,但须注意不定式的宾语要省略。例如:

  The question is so easy that I can work it out. →

  The question is easy enough for me to work out.

  The box is so light that he can carry it. →

  The box is light enough for him to carry.

  3. 当主句和从句的主语一致,且that从句是否定句时,可以用“too...to”来替换。例如:

  The girl is so young that she can't dress herself. →

  The girl is too young to dress herself.

  I was so tired that I couldn't go on with the work. →

  I was too tired to go on with the work.

  4. 当主句和从句的主语不一致,且that从句是否定时,如果要用“too...to...”替换“so...that...”,则用介词for引出动词不定式的逻辑主语,可以用“too...for sb. to do sth.”来替换,注意不定式的宾语要省略。

  The bag is so heavy that she can't move it. →

  The bag is too heavy for her to move.

  It is so hot that we can't sleep. →

  It is too hot for us to sleep.
