在前面的讲座中,我们讲到了不定式的一些用法,今天我们要讲的是 不定式的两个特殊用法
一个是:too
to,另外一个是:so as to 首先我们先来看第一个句型 t oo…to… 1)too…to 太…以至于… He is too excited to speak
他太激动了,说不出话来
---- Can I help you
需要我帮忙吗
---- Well, I’m afraid the box is too heavy for you to carry it, but thank you all the same
这箱子太重,恐怕你搬不动
2) 如在 too 前有否定词,则整个句子用否定词表达肯定, too 后那个词表达一种委婉含义,意 为"不太"
It’s never too late to mend
(谚语) 改过不嫌晚
3) 当 too 前面有 only, all, but 时,意思是:非常… 等于 very
I’m only too pleased to be able to help you
我非常高兴能帮助你
He was but too eager to get home
他非常想回家
第二个句型是:so as to 1) 表示目的;它的否定式是 so as not to do

汤姆对事故保持沉默是为了不丢掉他的工作
Go in quietly so as not to wake the baby
轻点进去,别惊醒了婴儿
2) so kind as to ---劳驾 Would you be so kind as to tell me the time
