too.to so.that such that区别及其用法
"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,必须注意以下三点 ：
第一要注意的是,这两句型所含的不同意义."so…that"有"如此程度,以致……"而 "too…to"则有"如此程度以致下……"的意思.故此在 "too…to"后不须再有否定字眼,若不,就有双竽否定的情况出现.如：
(×) The box is too small not to hold all these things.
(√) The box s too small to hold all these things.
其二要注意的是,虽然so与too都是用以表达形容词与副词和程度,但它们的结构却有别,请比较：
adj.so + + that + (从句)
adj.too + + to + .(动词原形)
例如：
1) Helen spoke so rapidly that we could not clearly understand her.Helen spoke too rapidly for us too understand.
(2) Mark was so angry that he could not speak.Mark was too angry to speak.
第三点,就是若 "so …that…" 句型中的从句中的主语与主句中的不,改用 "too…to…"句型表达时,我们可以将for + Noun/Pronoun结构用在to + infinitive之前.

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“su...

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.
