as...as...的用法詳解

時間: 若木631 分享

  其基本意思為“與…一樣”,其中的第一個as為副詞,其后通常接形容詞或副詞(用原級),第二個as可用作介詞(后接名詞或代詞)或連詞(后接從句)。使用時應注意以下幾點。如:

  (1) 在否定句中,第一個 as 也可換成 so。如:

  He doesn’t study as [so] hard as his brother. 他學習不如他弟弟努力。

  (2) 第二個as后接從句時,該as通常為連詞,但有時這個as還充當其后從句的主語或賓語,此時該as實為關系代詞。如:

  I gave him as much as he could eat. 他能吃多少,我就給了他多少。

  We’ve got food for as many people as want it. 我們的食物,無論多少人吃都夠了。

  (3) 在該結構的兩個as之間通常接形容詞或副詞的原級,但若涉及數(shù)量或程度,可用“as much+不可數(shù)名詞+as”和“as many+復數(shù)名詞+as”。如:

  You’ve made as many mistakes as I have. 你犯的錯誤和我犯的一樣多。

  I haven’t got as much money as I thought. 我不像原來想像的有那么多錢。

  其間接形容詞時,有時該形容詞還可修飾另一名詞,但這個名詞應帶有不定冠詞(注意詞序)。如:

  She is as good a teacher as her mother. 她和她媽媽一樣是位好老師。

  也可說。如:She is a teacher as good as her mother.

  但不說。如:She is as a good teacher as her mother. / They are as good teachers as us.

  (4) 該結構根據(jù)情況可用使用以下修飾語。如:(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等,并且這些修飾語必須置于第一個as之前,而不能置于其后。如:

  He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。

  This dress is twice as expensive as that. 這件連衣裙比那件貴一倍。

  (5) 若第二個as引導一個表示將來意義的從句,則該從句可用現(xiàn)在時表示將來,也可直接使用將來時態(tài)。如:

  We’ll get there as soon as you do [will]. 你一到,我們就到。

  (6) 在非正式場合(尤其是美國英語中),有時可以省略第一個as。如:

  When over forty, he married a woman poor as himself. 他在40多歲時娶了一個像他本人一樣窮的女人。

  另外,若意思明確,有時可省略第二個as及其后的相關詞語。如:

  The radios in that shop will be cheaper, but not as good. 那家商店的收音機會便宜些,但質量沒那么好。
