承受者, 如:
Cakes are eaten by Jim.
(执行者)(承受者)(承受者)(执行者)被动语态用法1、当我们不知道动作的执行者是谁,或者动作的执行者是谁并不重要时,需用被动语态。
2、当我们需要强调动作的承受者时,常用被动语态,此时如想同时指出动作的执行者,可用“by +动作执行者”来表示。如:Get it now before it is sold out.如:That CD-ROM was designed by Nancy Jackson.主动语态和被动语态的转换:主: Jim+eats+cakesCakes被:+are eaten+byJim语态转换Change the active voice into the passive voice.1.
