考研英语语法难点精析（二）

语法难点精析之三：too...to 结构表示肯定含义的情况

【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.
语法难点精析之四：every表示”每隔“的用法

⑴"every other+单数名词”

意思是“每隔一。。。”

如：every other day 每隔一天 every other tree 每隔一棵树

⑵“every+基数词+复数名词”或“every+序数词+单数名词”

意思是“每隔。。。”（较英语数词少一个）

如：every three days=every third day 每隔两天（或者译为每三天）

因此every two days=every other day 每隔一天（或者译为每两天）

⑶“every few+复数名词”

意思是“每隔几。。。”

如：every few days（每隔几天）
