三、用一个单词来代替被省略的成分
1.当从句或分句中的谓语动词省略时,有时须加一个助动词do合适的形式来代替。如:
(1)Anyone can’t break the rules.If you do,you will sure be punished.
任何人也不能违反纪律,如果你违反了,你将肯定要受到惩罚。

—Yes,I do.
是的,我喜欢。
2.当整个从句被省略时,可用so来代替。这样的主句谓语动词有:think,believe,guess,suppose,hope,be及疑问副词why,how,if等。如:
(1)—Do you think the thief will be put into prison?
你认为那个贼会被打入监牢吗?
—Yes.I think so.

(4)—He must be in the classroom now.
他现在肯定在教室里。
—If so,let’s go to the classroom to see him.
如果她在教室里,我们就去那儿看他吧。
3.当从句为否定,而整个从句被省略时,可写为don’t…so,也可只保留从句中的not。这样的主句动词有:think,believe,suppose等。如:
(1)—Do you think he will change his idea?
你认为他会改变主意吗?
—No.I don’t think so.
不,我认为他不会。
(2)—Do you think English is difficult?
