too to和so that有什么区别

"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(Adjective)与副词(Adverb)和程度，但它们的结构却有别，请比较：

adj. so + + that + Clause adv. (从句) adj. too + + to + Infinitive adv. (动词原形)

eg. (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 (Sub-ordinate clause)中的主语(Subject)与主句(Main

clause)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。请看下面的分析： eg. (1) The question was so difficult that we could not answer it.

(从句中的Subject为 "we" ，而主句的Subject为 "The question"。) = The question was too difficult for us to

answer. (注意 "it"不用写。) (2) Eddie ran so quickly that we could not catch up with him. (从句的Subject为

"we"而主句中的Subject为Eddie"。) = Eddie ran too quickly for us to catch up (注意 "him"不用写。)

艾迪跑得太快，我们都赶不上他 。

too to 意思：太，而不能。so that意思，如此，以至于。

同义，用法不同，一正一反 。比如：he is too tired to stand他太累了以至于站不起来！
he is so tired that he cannot stand
希望能帮到您

so + ad/ adj + that + 句子
too + adj/ adv + to do

He's so young that he can't join the army.
He's too young to join the army.

so,that.意思是太……以至于……
例句：She is so beautiful that I love her very much.
译:她太漂亮了以至于我非常爱她.
too,to.意思是太……而（不能）做……
例句：He is too tired to go.
译：他太累了,走不动了.

too to 是太~而不能~，后跟不定时
so that是太~以致于~，后跟从句
