英语语法求助(非谓语)!
在做题时,很多因动宾关系而用过去分词形式的题我觉得也可以用被动式来做.这时候该怎么判断是用被动式还是有过去分词呢?
过去分词与现在分词、被动式的用法区别
动词非谓语形式中的分词是高中英语重点语法项目之一,由于其变化较多,学生多认为难记,并易混淆,尤其是过去分词与现在分词的被动式的用法区别.现就这两种用法加以比较.
1.作原因状语时,过去分词与现在分词的的被动式being done可以互换.
如: Done in a hurry, her homework was full of mistakes=Being done in a hurry, her homework was full of mistakes. 这时以上两句意思都差不多等于: As her homework was done in a hurry, it was full of mistakes.
2.作原因状语时,分词的动作与谓语的动作同时或基本同时发生时,用being done不用done,
如: Being made fun of, she couldn't help crying.
3.作状语表行为方式或伴随时,常用过去分词(短语)而不用现在分词的被动式(being done).
如: The teacher came into the room, followed by a group of students. The old man stood there, surrounded by some children.
习惯上不用:Being followed by a group of students, the teacher came into the room.
4.作时间状语时,过去分词与having been done差别不大,其意义只等于一个时间状语从句.
如: Discussed many times, the problems were settled at last=Having been discussed many times, the problems were settled at last=After the problems had been discussed many times, they were settled at last. 但是:过去分词(短语)常用来作定语,而having been done却不能,只能作状语.
[误]The book having been given by her uncle is a present for her birthday.
[正]The book given by her uncle is a present for her uncle.
5.作定语用时,过去分词表示动作发生的时间早于谓语动词,或没有一定的时间性,只表示纯粹的被动关系,而being done则表示动作正在发生尚未结束,或差不多同时发生.
如: The thing being discussed here must be kept as a secret.
The things which are being discussed here must be kept secret. 而过去分词作定语没有这种时间关系.
如: The recorders made in this city are much cheaper.
