二語態(tài)
語法精講1. 當句子的主語是動作的執(zhí)行者時,謂語(vi. Vt.)的形式叫主動語態(tài);當句子的主語是動作的承受者時,謂語(vt.)用被動語態(tài)。被動語態(tài)的結構:
1)一般現(xiàn)在時:You are required to do this.
2)一般過去時:The story was told by her.
3)一般將來時:The problem will be discussed tomorrow.
4)現(xiàn)在進行時:The road is being widened.
5)過去進行時:The new tool was being made.
6)過去完成時:He said that work had been finished.
7)現(xiàn)在完成時:The novel has been read.
2.一些特殊的被動結構:
1)情態(tài)動詞的被動結構:The problem must be solved soon.
2)帶非謂語的被動結構:
The room is going to be painted. I hate being made fun of.
3)短語動詞的被動結構:
①(不及物)動詞+介詞:
agree to, ask for, call for, laugh at, listen to, look after, operate on, send for, talk about, think of. etc.
②(及物)動詞+副詞:
bring about, carry out, find out, give up, hand in, make out, point out, put away, turn down, work out, etc.
