用法辨析

    adv. (副词)

  • as用作副词时主要用来表示比较,意思是“像…一样；如同”。可以单独使用，但更多的是用在as...as结构中，其中第一个as是副词，其后可接形容词或副词,也可接其他成分，as前可有状语。第二个as可以是介词,也可以是连词。as用作副词时还可以指事物以同样的方式发生,意思是“和…一样”。
  • as...as结构多用于肯定式，偶尔也可用于否定式。表示同样意思的否定式多用so...as。as...as结构用于否定句时多用于口语，侧重“像…一样”；so...as结构则多用于书面语，侧重“像…那样”。
  • as...as结构表示的是同级比较，第一个as后的形容词或副词不可用比较级，必须用原级，比较的对象亦须属同类。
  • as...as结构表示数量或程度时，可用于“as much+(不可数名词+) as”或“as many+(可数名词复数+) as”结构。
  • 修饰as...as结构的常见词语有nearly,almost,just,exactly,half,quite,表示倍数或次数的形容词，“数词+times”等。这些修饰语都放在as...as结构之前。
  • 使用as...as结构时，若第一个as后的名词是单数可数名词并有形容词修饰，则应使用“as+ adj.+ a/an+ n. ”结构，即不定冠词应位于形容词和名词之间。第二个as后面的名词或代词的格不同，意思也不同。
  • as...as结构中后一个as用作连词时引导的从句常为省略句，省略从句中的动词可使主句的意义得到加强；反之，重复从句中的动词则可使从句的意义得到强调。
  • 使用as...as结构时，在一定的上下文中可以省去其中的一个。
