Grammar Grammar I. 动词（Verbs ） 1. 被动语态（Passive Voice ） 主动语态和被动语态 1) 英语动词有两种语态，即主动语态（ ）和被动语态（ Active Voice Passive Voice ）。当主语为动作的执行者时，谓语的形式为主动语态；当主语为动作的 承受者时，谓语要用被动语态。例如： （主动语态，句子的主语 是动作 Many people speak English. many people speak 的执行者） （被动语态，句子的主语 是动作 English is spoken by many people. English speak 的承受者） Bell invented the telephone in 1876. （主动语态） The telephone was invented by Bell in 1876. （被动语态） 2) 被动语态的构成 被动语态由“助动词 ＋及物动词的过去分词”构成。助动词 有人称、数 be be 和时态的变化，其变化规则与 作为连系动词时完全一样。现以动词 为例， be ask 将一般现在时和一般过去时被动语态的肯定式、否定式及疑问式列表如下： 肯定式 否定式 疑问式 I am asked … I am not asked … Am I asked …? He/She is asked … He/She is not asked … Is he/she asked …? 一般现在时 We/You are asked … We/You are not asked … Are we/you asked …? They are asked … They are not asked … Are they asked …? I was asked … I was not asked … Was I asked …? He/She was asked … He/She was not asked … Was he/she asked …? 一般过去时 We/You were asked … We/You were not asked … Were we/you asked …? They were asked … They were not asked … Were they asked …? 3) 含有情态动词的被动语态 含有情态动词的被动语态由“情态动词＋be ＋及物动词的过去分词”构成。例 如： Teenagers should be allowed to make their own
