歷史思潮  >>>  民初教育及人才培養


  請看下面一道題:
  —I was riding along the street and all of a sudden, a car cut in and knocked me down.
  —You cannot be____careful in the street.
  A. much  B. very  C. so  D. too
  分析:該題考查的是“cannot...too...”結構的用法。答案為D。題意為:
  ——我在馬路上騎車,突然一輛汽車超車,撞了我。
  ——在馬路上(騎車),你越小心越好。
  “cannot...too...”結構是中學英語課本中的一個重要句型。該結構表示“無論怎么……也不算過分”“越……越好”“要格外……”“應該特別……”等意義。表示此意義的句型結構有下列幾種:
  1. cannot+be+too+形容詞/副詞
  We cannot be too careful in doing experiments.
  我們做實驗越仔細越好。
  I cannot thank you too much.
  我無論怎么樣感謝你也不過分。
  2. cannot+over-動詞或cannot+be+over+形容詞
  We cannot overemphasize the importance of learning a foreign language.
  我們無論怎么強調學外語的重要性也不過分。
  We cannot be over vigilant.
  我們應該特別警惕。
  3.cannot+動詞+too much
  We cannot praise him too much.
  我們無論怎樣贊揚他也不算過分。
  He is very reliable. You can't trust him too much.
  他很可靠,是最值得你信賴不過的。
  4.cannot+動詞+形容詞/副詞+enough
  含not的結構也可被含never, hardly, scarcely等否定詞的結構取代。例如:
  You can never be strong enough.
  身體越健康越好。
  Drinking water can never be pure enough.
  飲用水越純越好。
  5.cannot+動詞+too many+可數名詞或cannot+動詞+too much+不可數名詞
  It is wrong to think that one cannot bear too many children.
  認為一個人孩子生得愈多愈好是錯誤的。
  I think it right that one cannot learn too much knowledge.
  我認為一個人的知識愈多愈好。
  6.It is impossible to...too...=cannot...too...
  It is impossible to emphasize this point too much.
  要特別強調這一點。
  與cannot...too...相似的句型結構主要有:
  1.cannot help+doing:該結構意為“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.
  看到中國的長城,我們不禁浮想聯翩。
  I couldn't help crying when I heard the bad news.
  當我聽到那不幸的信息,我不禁大哭起來。
  類似結構:“cannot help but do sth.”表示“不得不、忍不住”。例如:
  We could not help but walk from dawn to dusk.
  我們不得不從黎明走到黃昏。
  I couldn't help but cry.
  我忍不住哭了起來。
  2.cannot but do sth.:該結構表示“不得不……”。例如:
  I cannot but admire his courage.
  我不得不欽佩他的勇氣。
  I couldn't but laugh on reading such a funny joke.
  讀到如此滑稽的笑話,我忍不住笑了。
  注意:①在這個句式里,cannot后省略了do anything。例如:
  He cannot but agree.
  他不得不同意。
  ②can but do sth.表示“只得……”。例如:
  The boy made an apology to his teacher, so the teacher could but give up the idea of punishing him.
  那男孩向老師道了歉,老師只得打消懲罚他的念頭。
  ③類似這一結構的“cannot choose but do 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,他們只得待在家里。
