英语语法之副词精讲
⑴ as…as…常构成一些词组：
as soon as…(一旦…就…), as well as…(同样), as+形容词/副词+as possible(尽可能……地)。如：Please ring me up as soon as you get to Beijing.(请你一到北京就给我写信。)/ Miss Gao hurried to the school gate as quickly as possible.(高小姐尽快地赶到了校门口。)
[注释] “as long / much as + 名词”可以表示“长达/多达…”的含义。如：The house costs as much as five hundred thousand yuan.(那幢房子花费高达50万元。)/ They stayed in the cave(山洞)as long as two weeks.(他们呆在山洞里长达两周。)
⑵ later、after、ago、before的用法：
①“一段时间+later/ago”分别表示“(多久)以后/以前”,主要用于过去时态。
②“after/before+某个时刻”分别表示“在某时刻之后/之前”,此时两个词是介词。
③ago与before：ago只能用于过去时,before用于完成时。如：He had an accident a week ago.(一周前出了一个事故)/ Some years later, the boy became a very famous singer.(数年后这个男孩成了著名的歌唱家)/ Have you been there before?(你从前到过那儿吗？)/ After a few years he gave up smoking.(过了几年他戒了烟。)
⑶ above、below、over、under的用法：
在上下方用above和below,在高低处用over和under.如：The stars are high above in the sky.(星星高挂在空中) / A plane flew over quickly.(一架飞机从头顶飞过。)
当above、below、over、under是介词性质时,意义相似。
⑷ too、also、either、nor的'用法：
too(“也”)用于肯定句和疑问句的末尾,且用逗号隔开；also(“也”)用于肯定句句子谓语动词之前；either(“也”)用于否定句末尾,也用逗号隔开；nor(“也不”)用于倒装句句首；如：Are you American,too?(你也是美国人吗？)/ He is not happy and I am not happy, either.(他不愉快,我也不。) / He didn’t watch the football game. Nor did I.(他没有看足球赛,我也没有。)/ You can also find the market is very good.(你还可以发觉那个市场很好。)
⑸ enough、too、so、very、quite、very much的用法：
enough (“足够,十分”)放在形容词或副词之后；too(“太”)、very(“非常”)、quite(“相当”)、so(“如此地”)等放在形容词或副词之前,very much(“非常”)放在动词之后。如：It’s too/so/very/quite expensive.(它太贵/那么贵/非常贵/相当贵。)/ I don’t like sweets very much.(我不很喜欢糖果)
[注意] very与 much的区别：very修饰形容词、副词的原级和现在分词形容词,much修饰形容词和副词的比较级；much还可以修饰疑问句和否定句中的动词,very不可以。如：He is very stupid.(他很笨)/ The film was very moving and everyone swept.(电影非常动人,大家都哭了)/ You must work much harder or you will fail to enter the good school.(你得学习更努力,不然你考不进那所好学校)/ I don’t like him much.(我不太喜欢他)。
