不定代词 & 地点/时间副词
讲解+练习题
本次语法点包含不定代词(some/any/no/every + one/thing/where)和地点/时间副词(some/any/no/every + where/time),核心用于表达“不确定的人、事物、地点或时间”。
不定代词由some/any/no/every与one/thing/body组合而成,some-和any-是核心区分点,no-表否定,every-表全部。
类别 | 构成 | 含义 | 肯定句 | 否定句/疑问句 | 特殊用法 |
指人 | someone/anybody/everyone/nobody | 某人/任何人/每个人/没人 | someone(常用) | anybody(常用) | everyone无复数,后接单数动词 |
指物 | something/anything/everything/nothing | 某物/任何物/一切/没东西 | something(常用) | anything(常用) | nothing = not anything |
指地点 | somewhere/anywhere/everywhere/nowhere | 某地/任何地方/到处/无处 | somewhere(常用) | anywhere(常用) | nowhere = not anywhere |
- some-系列:主要用于肯定句,表“不确定的某人/某物/某地”;也可用于希望得到肯定回答的疑问句(如Would you like something to drink?)。
- any-系列:主要用于否定句和疑问句,表“任何的人/物/地方”;也可用于肯定句表“任何”(如Anybody can do it.)。

- no-系列:本身含否定意义,相当于“not + any-系列”(如nobody = not anybody),用于肯定句表否定含义。
- every-系列:表“全部、每一”,后接单数动词,不可与not连用表部分否定(部分否定用not all)。
与不定代词结构一致,some/any/no/every还可与**where(地点)/time(时间)组合成副词,用法与不定代词一致:
- sometime(某个时间)、anytime(任何时间)、everytime(每次)、notime(没时间)
- somewhere(某地)、anywhere(任何地方)、everywhere(到处)、nowhere(无处)
- 主谓一致:everyone/nobody/someone等作主语时,谓语动词用单数(如Everyone likes music.)。
- 否定叠加:no-系列本身表否定,不可再与not连用(如×Not nobody likes it. √Nobody likes it.)。
- 词性区分:不定代词(something)后不可接介词,地点副词(somewhere)也不可接介词(如×go to somewhere √go somewhere)。
