非谓语动词done在什么情况下表被动?如果主语和这个动词是被动关系,而且题目要求选择非谓语动词,就用done形式,
答
done在非谓语中是过去分词,一般情况下表被动、完成.但如果动词不及物,那就只表完成,不表被动,如 fallen leaves, boiled water指落叶,开水,fallen和boiled只表已落下,已沸腾过,不表被动.
非谓语中不仅仅过去分词可以表被动,还有不定式的被动to be done,现在分词的被动being done,having been done 动名词的被动being done.使用时要看是否完成.
一般情况下,表被动,完成,done
表被动,进行,being done
表被动,未发生/将来 to be done
在表被动完成的情况下,如果还有表达次数或时间的状语相连,则用having been done
例:He is said to be sent to Beijing.据说他将被派往北京.(被动,将来)
He is reading a book written by Bill Gates.他在读一本比尔盖茨写的书.(被动完成)
Having been warned many times,the boy got to school late again.已被警告了许多次,这个男孩上学又迟动了.(被动完成,加表次数的状语)
Being watched,he didn't want to eat anything.被人盯着,他不想吃任何东西.(被动,进行)
