一．结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。是由so...that(如此……以至于……)；such...that(如此……以至于……)等从属连词引导的状语从句。
知识点01
…+so+形容词/副词＋that从句。
知识点02
…+such+a/an+形容词＋单数可数名词＋that从句。
知识点03
…+so+形容词＋a/an＋单数可数名词＋that从句。
Tom is so clever a boy that he can answer the question. 汤姆很聪明，他能回答这个问题。
知识点04
…+such+形容词＋复数可数名词/不可数名词＋that从句。
在“形容词+可数名词复数/不可数名词”结构中，当名词前有many, much, few, little表示数量的多少时，名词前用so（构成：“so+many/few+复数可数名词+that从句”或“so+much/little+不可数名词+that从句”）。
二．so… that引导的结果状语从句可以转换成不定式的简单句：
知识点01
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。
1.The man is so strong that he can lift the heavy box. 这个男人如此的强壮，以至于他能举起这只沉重箱子。
→The man is strong enough to lift the heavy box. 这个男人如此的强壮，以至于他能举起这只沉重箱子。
2.He was so clever that he can understand what I said. 他是如此的聪明，他能理解我所说的话。
→He was clever enough to understand what I said. 他是如此的聪明，他能理解我所说的话。
知识点02
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。
1.I was so tired that I couldn’t go on with the work.=I was too tired to go on with the work. 我太累了，不能继续工作了。
2.The girl is so young that she can’t dress herself.=The girl is too young to dress herself. 这个女孩太小了，还不能自己穿衣服。
知识点03
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。
1.The box is so light that he can carry it. =The box is light enough for him to carry. 这个箱子如此轻以至于我可以搬动它。
2.The question is so easy that I can work it out.=The question is easy enough for me to work out. 这个问题很容易，我们能算出。
知识点04
当主句和从句的主语不一致，且that从句是否定时，可以用“too...for sb. to do sth.”来替换，注意不定式的宾语要省略。
1.It is so hot that we can’t sleep.=It is too hot for us to sleep. 天气这么热，我们睡不着。
2.The bag is so heavy that she can’t move it.=The bag is too heavy for her to move. 这个袋子太重了，她搬不动它。
