      as...as...的用法詳解

      時(shí)間: 若木631 分享

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

        (1) 在否定句中,第一個(gè) as 也可換成 so。如:

        He doesn’t study as [so] hard as his brother. 他學(xué)習(xí)不如他弟弟努力。

        (2) 第二個(gè)as后接從句時(shí),該as通常為連詞,但有時(shí)這個(gè)as還充當(dāng)其后從句的主語(yǔ)或賓語(yǔ),此時(shí)該as實(shí)為關(guān)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(wú)論多少人吃都?jí)蛄恕?/p>

        (3) 在該結(jié)構(gòu)的兩個(gè)as之間通常接形容詞或副詞的原級(jí),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(fù)數(shù)名詞+as”。如:

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

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

        其間接形容詞時(shí),有時(shí)該形容詞還可修飾另一名詞,但這個(gè)名詞應(yīng)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(shuō)。如:She is a teacher as good as her mother.

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

        (4) 該結(jié)構(gòu)根據(jù)情況可用使用以下修飾語(yǔ)。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(yǔ)必須置于第一個(gè)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(gè)as引導(dǎo)一個(gè)表示將來(lái)意義的從句,則該從句可用現(xiàn)在時(shí)表示將來(lái),也可直接使用將來(lái)時(shí)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(chǎng)合(尤其是美國(guó)英語(yǔ)中),有時(shí)可以省略第一個(gè)as。如:

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

        另外,若意思明確,有時(shí)可省略第二個(gè)as及其后的相關(guān)詞語(yǔ)。如:

        The radios in that shop will be cheaper, but not as good. 那家商店的收音機(jī)會(huì)便宜些,但質(zhì)量沒(méi)那么好。

      as...as...的用法詳解

      其基本意思為與一樣,其中的第一個(gè)as為副詞,其后通常接形容詞或副詞(用原級(jí)),第二個(gè)as可用作介詞(后接名詞或代詞)或連詞(后接從句)。使用時(shí)應(yīng)注意以下幾點(diǎn)。如: (1) 在否定句中,第一個(gè) as 也可換成 so。如: He doesnt study as [so
