so...that/so that/such...that用法详解
一、“so... that...如此……以致于……”,引导结果状语从句,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...”,意思也是“如此……以致于……”,也引导结果状语从句,其句型结构可分以下三种:
1. such+a(an)+adj.+单数可数名词+that从句 He is such a clever boy that everybody likes him.
He was such an honest(诚实的) man that we believed him very much. 2、such+adj.+复数可数名词+that从句
They are such interesting novels that I want to read them once again.(反复) 3、such+adj.+不可数名词+that从句
He has made such great progress(进步) that the teachers are pleased with him. 三、so that 意思是"以便/为了……",引导目的状语从句。例如: I got up early so that I could catch the early bus.
Please open the window so that we can breathe(呼吸) fresh air. 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:
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: He was so clever that he can understand what I siad. → He was clever enough to understand what I siad.
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. 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.
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.
