【英语语法】什么是被动语态,珠海IBS英语学校编辑和大家分享什么是被动语态和有关例句说明,请阅读下文。
什么是被动语态?
英语有两种语态:主动语态和被动语态。主动语态表示主语是谓语动词的执行者,如:She takes care of the child.被动语态表示主语是谓语动词的承受者,如: The child is taken care of by her.原主动语态的主语变成短语by her,在被动句中作状语。
主动语态变被动语态通常的办法是:将主动结抅中的宾语变为被动结构中的主语,将主动结抅中的谓语动词变为"be / get +过去分词"形式,将主动结构中的我们在平常的英语交流中,尽量使用主动语态,但在下列情况下,则通常使用被动语态:
1.不知道动作的执行者是谁,或没有必要指出动作的执行者吋。如:
The glass is broken.玻璃杯破了 。
Letters are collected at eight every morning.
信件每天早晨八点收取。
2.为了强调或突出动作的承受者时。如:
The desk was made by Master Wang.这张课桌是王师傅做的。
The bag was taken away by his sister.
那个口袋是她姐姐提走的。
3.在上下文中,为了使句子间连接紧密时。如:
I have a new motorbike. It was given to me as a birthday present by my father.
我有辆新摩托车。它是父亲送给我作为生日礼物。
4.在新闻报道中,为了表明报道的客观性而避免主观性的透露吋。如:
A car accident happened on the high way this morning. Three men were killed , the wounded were taken away to hospital at once and policemen were sent there to cope with the event.
今天早晨高速公路上发生了一起车祸,三人丧生,伤员马上被送往了医院,并马上派了警察去处理这一事件。
