“so.that.”句型的意思是“如此/这么以致于”，常引导结果状语从句。“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： 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 cant look after herself. 2. The boy ran so fast that I couldnt catch him. 3. He was so angry that he couldnt 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. There is so little water in the glass that I cant 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 wont 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 cant dress herself. The girl is too young to dress herself. I was so tired that I couldnt 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 cant move it. The bag is too heavy for her to move. It is so hot that we cant sleep. It is too hot for us to sleep.
