( 2003 北京春) —— I was riding along the street and all of a sudden, a car cut in and knocked me down.

    ----

You can never be ________ careful in the street.

  A. much B. very C. so D. too

  分析:该题考查的是“ cannot ( never )……too…… ”结构的用法。答案为 D .此题意为:

  ––– 我在街上骑车,突然一辆汽车超车,把我撞倒。

  ––– 在街上骑车,你越小心越好。

  “ cannot…… too…… ”结构表示“无论怎么……也不算过分”、“越……越好”、“要格外……”、“应该特别……”等意思。表示此意的结构有下列几种:

  1. cannot +动词+ too +形容词或副词,例如:

  We cannot be too careful in doing experiments. 我们做实验时越仔细越好。

  I cannot thank you too much. 我无论怎么感谢你也不过分。

———how did you find the film Horry Potter and the Deathly Hollows ?

———it's really amazing. I can't think too highly of it.

  2. cannot + over- 动词 /cannot + be + over- 形容词,例如:

  We cannot overemphasize the importance of learning a foreign language. 我们无论怎么强调学外语的重要性也不过分。

  We cannot be overvigilant. 我们应该特别警惕。

  3. cannot +动词+ too much ( much enough ) ,例如:

  We cannot praise him too much. 我们无论怎样表扬他也不算过分。

  He is very reliable. You can't trust him too much ( much enough )。 他很可靠,他是你最值得信赖的人。

  4. cannot +动词+形容词或副词+ enough

  在“ cannot……too…… ”结构中的 too 可换成 enough , sufficient 或 sufficiently ; not 也可换成 never , hardly , scarcely 等否定词。例如:

  You can never be strong enough. 强壮的身体有百利而无一害。

  Drinking water can never be pure enough. 饮用水越纯越好。

I can never thank you enough for you generosity.
中文意思:
我对您的慷慨大度永远感激不尽

  5. cannot +动词+ too many +可数名词 / too much +不可数名词,例如:

  I think it right that one cannot learn too much knowledge. 我认为一个人的知识愈多愈好。

  It is wrong to think that one cannot bear too many children. 认为一个人孩子生得愈多愈好是错误的。

  6. It is impossible ( difficult ) to…… too…… = cannot……too…… ,例如:

  It is impossible to emphasize this point too much. (= One cannot emphasize this point too much. )要特别强调这一点。

  与 cannot……too…… 相似的结构主要有:

  1. cannot help + doing :该结构意为“禁不住做……”、“忍不住干……”,指“身不由己地去做某事”。例如:

  We could not help thinking when we saw the Great Wall in China.

  看到中国的长城,我们不禁浮想联翩。

  I couldn't help crying when I heard the bad news. 听到那不幸的消息,我忍不住大哭起来。

  “ cannot help but do sth. ”也表示“不得不、忍不住……”。例如:

  We could not help but walk from dawn to dusk. 我们不得不从黎明走到黄昏。

  Hearing the inspiring news, we couldn't help but cheer. 听到这个鼓舞人心的消息,我们不禁欢呼起来。

  2. cannot but do sth :该结构表示“不得不……”。例如:

  I cannot but admire his courage. 我不得不钦佩他的勇气。

  I couldn't but laugh on reading such a funny joke. 读到如此滑稽的笑话,我忍不住笑了。

  在上面句式里,可以说 cannot 后面省略了 do anything .例如:

  The prisoner could not ( do anything ) but hand in his knife. 那个犯人不得不交出刀子。

  can but do sth. 表示“只得做某事”。例如:

  The boy made an apology to his teacher, so the teacher could but give up the idea of punishing him. 那男孩向老师道了歉,老师只得打消惩罚他的念头。

  类似这一结构的 cannot choose but to sth 也表示“不得不……”、“只得……”。例如:

  It rained hard, so they couldn't choose but stay at home. 雨下得很大,他们只得呆在家里。
