1)too…to 太…以至于…。例如:
He is too excited to speak. 他太激動了,說不出話來。
---- Can I help you ? 需要我幫忙嗎?
---- Well, I’m afraid the box is too heavy for you to carry it, but thank you all the same.
不用了。這箱子太重,恐怕你搬不動。謝謝。
2) 如在too前有否定詞,則整個句子用否定詞表達肯定,too 后那個詞表達一種委婉含義,意 為"不太".例如:
It’s never too late to mend. 改過不嫌晚。(諺語)
3) 當too 前面有only, all, but時,意思是:非常… 等于very.例如:
I’m only too pleased to be able to help you. 能幫助你我非常高興。
He was but too eager to get home. 他非常想回家。
