一般现在时的被动语态
【概念】
1.语态:
英语中有主动语态和被动语态之分。主动语态表示主语是动作的执行者,而被动语态则表示主语是动作的承受着。如果我们不知道谁是动作的执行者或需要强调动作的承受者时,就必须用被动语态。
2.一般现在时的被动语态:
一般现在时的被动语态表示通常性、规律性、习惯性、真理性的状态或者动作有规律发生的一种状态且主语是动作的承受者。
3.概念点拨:
一般现在时的被动语态与一般现在时在时态上是一致的,强调动作或状态的通常性、规律性、习惯性、真理性,其区别在于前者的主语是动作的承受者,后者的主语是动作的发出者。
如Our classroom is cleaned by us every day.(我们的教室每天由我们打扫。)
根据时间状语every day可知,句中clean的动作是习惯性的,主语Our classroom是clean这一动作的承受者,使用的是一般现在时的被动语态。
【结构】
1.一般现在时的被动语态,其主要结构为:
主语(动作接受者)+is/am/are+动词的过去分词+(by+动作执行者)
Football is played in most countries in the world.
2.被动语态的句型总结如下:
①肯定句:主语+am/is/are+动词的过去分词+(by+人代宾格 )+其他
eg.English is studied (by us) every day.
②否定句:主语+am/is/are+not+动词的过去分词+(by+人代宾格 )+其他
eg.English is not studied (by us ) every day.
③一般疑问句:Is/Am/Are+主语+过去分词+(by+人代宾格 )+其他?
eg.Is English not studied (by us ) every day?
④特殊疑问句:What/Where/When+am/is/are+主语+动词的过去分词+(by+人代宾格 )+其他?
eg.What is this kind of sweater made of?
