被动语态的使用

 被动语态的使用     被动语态用得不如主动语态多，但在某些情况下须要用或宜用被动语态。   1.不知道或不必指明动作的发出者时用被动语态。   He was born in 1971.   他出生于1971年。   The origin of the universe will probably never be explained.   宇宙的起源大概永远不会有答案。   2.要强调或突出动作的承受者时用被动语态。   The plan has already been canceled.   这个计划已经取消。   Dick was dismissed.   迪克被开除了。   3.为了使语气委婉，有意不说出动作的发出者时用被动语态。   Suggestions will be heartily appreciated.   诚恳欢迎提出建议。   4.为了修辞的需要,避免变换主语或过长的主语时用被动语态。   The king loved his people and was loved by them.   国王爱人民,也为人民所爱。   The picture was painted by a good friend of mine who came from Australia.   这幅画是我的一位来自澳洲的好友画的。   5.BE+过去分词并不一定都是被动语态句，也可能是联系动词+主语补语结构。区别在于被动语态句表示的是一个动作，而联系动词+主语补语结构表示主语的特徵或状态。   The picture was drawn by my cousin.   这幅画是我表哥画的。   是被动语态句。   The picture is well drawn.   这幅画画得很好。   是联系动词+主语补语。
