  以下是我为大家整理的as...as的用法 总结 ,希望能帮助大家更好地认识as...as这个词组,提高英语水平。

   一、基本意思为“与…一样” ,其中的第一个as为副词,其后通常接形容词或副词(用原级),第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点。如:

  (1) 在否定句中,第一个 as 也可换成 so。如:

  He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。

  (2) 在该结构的两个as之间通常接形容词或副词的原级,但若涉及数量或程度,可用“as much+不可数名词+as”和“as many+复数名词+as”。如:

  I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。

  You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。

  其间接形容词时,有时该形容词还可修饰另一名词,但这个名仔纳词应带有不定冠词(注意词序)。如:

  She is as good a teacher as her mother. 她和她妈妈一样是位好老师。

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

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

  (3) 该结构根据情况可用使用以下修饰语。如:(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等,并且这些修饰语必须置于第一个as之前,而不能置于其后。如:

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

  This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。

  (4) 第二个as后接歼戚虚从句时,该as通常为连词,但有时这个as还充当其后从句的主语或宾语,此时该as实为关系代词。如:

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

  We’ve got food for as many people as want it. 我们的食物,无论多少人吃都够了。

  (5) 若第二个as引导一个表示将来意义的从句,则该从句可用现在时表示将来,也可直接使用将来时态。如:

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

  (6) 在非正式场合(尤其是美国英语中),有时可以省略第一个as。如:

  When over forty, he married a woman poor as himself. 他在40多岁时娶了一个像他本人一样穷的女人。

  另外,若意思明确,有时可省略第二个as及其后的相关词语。如:

  The radios in that shop will be cheaper, but not as good. 那家商店的收音机会便宜些,但质量没那么好。

   二、“as + 形容词或副词原级 + as…” 意为“和……一样”,表示同级的比较 ,但要注意第一个 as 为副词,第二个 as 为连词。根据比较对象和性质的不同又可以把此种结构分为三种:

  (一)“ as … as …结构”用于表示不同人或物同一性质的比较,意为“……和……一样…… " 。例如

  The tree is as tall as the building(is) .

  这棵树和那栋楼一样高。

  注意此结构也常用于形象比喻中: as cool as cucumber 沉着的, as stubborn as a mule 非常顽强的,倔强的, as clear as crystal 非常透明的, as poor as a church mouse 非常贫困的, as busy as a bee 像蜜蜂一样忙碌, as easy as ABC 像 ABC 一样容易, as deep as a well 像井一样深, as light as a feather 像羽毛一样轻, as soft as butter 像黄油一样软。这些 短语 生动活泼,浅显易懂,记住这些短语可以提高学生的 英语写作 和口语能力。

  (二)“ as … as …结构”用于表示同一个人或物不同性质的比较,意为“既……又……” 。例如:

  This swimming pool is as wide as it is long.

  这个 游泳 池宽度和长度相等。

  (三)“ as … as …结构”用于表示两个人或物不同性质的比较,表示程度相同或相当,意为“……而……”。在否定句中结构是“ so/as…as… ”。例如:

  He was as experienced as his brother was green .

  他 经验 丰富,而他兄弟却涉世未深。

  He was as handsome as his wife was beautiful .

  他长得非常英俊,他的妻子也长得非常漂亮。

  He cannot run so/as fast as you.

  他没你跑得快。

  Danny is not so/as wise as he is witty .

  丹尼为人风趣,但欠明智。

  需要注意的是: “as + 形容词或副词原级 + as…” 结构的变体形式是“ as + 形容词 + a + 单数名词 + as 或 as + many/much + 名词 + as ”。意为“……和……一样…… " 。例如:

  I don't want as expensive a car as this. = I don't want a car as expensive as this .

  我不要这么贵的汽车。

  This is as good an example as the other is.

  这个例子和另外一个例子一样好。

  Tony is as clever a boy as his brother .
