2015年在职GCT考试语法难点精析(5)

　　【语法难点之too...to 结构表示肯定含义的情况】

　　我们知道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.

　　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.

　　It is too much to say that he is a fool.
