too.to so.that such that区别及其用法

so...that... 如此……以致于……
...so that... 以便于，为了
“so...that...”句型的意思是“如此/这么……以致于……”，常引导结果状语从句
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：
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...”。
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 1. 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.
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.
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.
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.

"too…to"和 "so…that…"这两个句型容易混淆.下面的句子可用两种方式表达 I was so tired that I couldn”t move.OR:I was too tired to move.我累得不能动.故必须留意并熟记so与that配搭,而too是与to配拾的.此外,...
