3、ing so.例2:His expression suggested that he _(be)angry.例3.翻译：快点，否则你就会迟到。waswasHurry up,or youll be late.四、忌将as if/though与if完成等同起来，造成动词形式的误用。例1.He treated her as if she _ his own daughter.A.were B.had been C.has been D.is例2.He looks as if he _ the news.A.hears B.heard C.had heard D.has heard五、忌不分析虚拟条件

4、从句的创新形式，因不会追根求源而乱选一气。（一）句型还原1、倒装句型还原例：_ he _ time,he would certainly have come to the party last night.A.Has;had B.If;had C.Did;have D.Had;had2、省略句型还原例：If only I _ ten years younger!A.am B.would be C.should be D.were=If he had had time=If I were ten years young!I would be very happy3、疑问句型还原例：-He did

6、e=If he had asked you,you would have gone.=If it had not been for your help.=If you had not helped me.（二）创新语境还原if虚拟条件从句通常用if从句来体现虚拟背景，但有时也可用with/without 短语、or/otherwise短语、but for短语、介词短语、but并列句和一个真实语气的句子，来代替虚拟语境。1.With/without 语境还原例：I _ greater progress with his help.A.would make B.would have made C.
