Unit 5 Good manners
● 考点归纳so...that... such... that... enough to too……to
一、 so... that...句型中的so是副词，常常修饰形容词或副词，常用句型为：主语 谓语 so adj. / adv. that从句。
1. He is so young that she can't look after herself. 2. 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……”但当名词前有表示数量的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.
但是：There is such a little(小) bird that I can't see it.
如果名词是可数名词单数才要加a 和an, 反过来如果是可数名词单数, 前面一定要加a或an
He is so lazy a boy. / He is such a lazy boy.
She is so lovely a girl that everyone loves her. She is such a lovely girl that everyone loves her.
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.
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 said. → He was clever enough to understand what I said.
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.
5. 当that引导的从句为否定式时，若从句主语与主句主语相同, so．．．that可转换为enough to的否定结构；若从句主语与主句主语不相同时，so．．．that可转换为 enough for sb．to 的否定结构。注意：转换后的形容词（副词）要用其相应的反义词。例如：
The man is so old that he can't go to work．→The man isn't young enough to go to work
The desk is so heavy that I can't move it．→The desk isn't light enough for me to move．
6. enough to的句式为否定式时，enough to可以转换为too．．．to结构。但转换后的too．．．to结构中的形容词（副词）要用其相应的反义词。例如：
He is not old enough to do the job. → He is too young to do the job.
Tom didn't walk slowly enough for us to keep up with him．→Tom walked too fast for us to keep up with him.
由中考试题看so...that, too...to 和enough to的转换
1． The water was so dirty that we couldn't drink it． The water was ____ dirty for us ____ drink．（2001上海市）
2． The child is so young that he can't put on his clothes． The child isn't ____ ____ ____ put on his clothes．（'99四川宜宾）
