来源:百度文库 编辑:中科新闻网 时间:2024/05/07 23:46:33

too + adj. +to + do
太。。。。以至于不能。。。
句中不和not连用
He was too tired to finish his work before 5 p.m.
他太累了以至于不能在下午5点前完成工作。

too...to 结构表示肯定含义的情况:
too...to结构一般表示否定含义,意为“太...以致于不能”。
eg:He is too old to work.
他年纪太大以致于不能工作。

但too...to在下列情况下却表示肯定含义:
⑴当too前或to前有否定词构成双重否定时。
eg:English is not too difficult to learn.
英语并不太难学。
He is too wise not to see that.
他很聪明,不会不懂这一点。

⑵当too后是glad,pleased,happy,delighted,satisfied,ready,willing,kind,apt,good,true,easy,near,careful,well,early,delicious,eager,anxious等形容词或副词时。
eg:They are too anxious to leave.
他们急于离开。
He is too ready to help others.
他总是乐于助人。
与这些词连用时,too前还常加上only,all,but,just,simply等副词,意思不变,因为这些词加上too后与very同义。
eg:I"m only too glad to see you .
见到你非常高兴。
They are but too pleased to hear the news.
他们听到这个消息,非常高兴。

⑶与cannot连用时。
eg:You cannot be too careful(=You can never be careful enough) to do your homework.
你做作业越仔细越好(=无论怎样仔细也不过分)。

⑷当不定式在句中作定语或真正的主语时。
eg:There are too many problems to be solved.
有很多问题有待解决。

only too...to do sth.=very...to do sth. 做某事很
far too...to=too...to 太……以至于不
