1、as.as用法的详细说明as.as其基本意思为;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)，其次个as可用作介词(后接名词或代词)或连词(后接从句)。下面我为大家介绍as.as用法的具体说明，希望对大家有用。as.as用法的具体说明如下：(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+不行数名词+as;和;as many+复数名词+
2、as;。如：You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(留意词序)。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
3、as her mother. / They are as good teachers as us.(3) 其次个as后接从句时，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。(4) 该结构依据状况可用运用以下修饰语。如：(not) nearly, almost, just, nothing like, exactly,
4、not quite, half, one-ten, twice, three times, 30 per cent等，并且这些修饰语必需置于第一个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。(5) 若其次个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，也可干脆运用将来时态。如：We’ll get there as soon as you do wi
5、ll. 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，有时可省略其次个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。;as + 形容词或副词原级 + as… 意为;和……一样;，表示同级的比较，但要留意第一个
6、as 为副词，其次个 as 为连词。依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。留意此结构也常用于形象比方中： as cool as cucumber 镇静的， as stubborn as a mule 特别坚韧的，倔强的， as clear as crystal
