3、。过去完成时态由had+v.ed(动词的过去分词)构成。e.g.AudreyhadbeenamodelbeforeshebecameaHollywoodsuperstar.WhenIarrivedatthestation,thetrainhadleft.ShehadfinishedallherhomeworkbeforeshewatchedTV.过去完成时态的一般疑问句把had提到主语之前；否定句在had后加not。e.g.Hadyouseenanyofherfilmsbeforeyousawthisone?Yes

7、表示主观愿望。e.g.Ihavetofinishmyworkontime.(外界要求我完成)Imustfinishmyworkontime.(自己想完成)haveto的否定式是don’thaveto,表示“不必要”；must的否定式是mustnot,表示“一定不能”、“不允许”。e.g.Shedoesn’thavetodoallthehomework.Youmustn’tputyourbikehere.CUsing‘whynot’,‘whydon’tyou’andperhaps.用whynot,whydon’tyo

8、u和perhaps来提建议。whynot/whydon’tyou后跟动词原形，也是提出建议的两种方式，表示“为什么不……”,两者可以互换。e.g.Whynotgooutforawalk?Whydon’tyougooutforawalk?WhynotwearaT-shirt?=Whydon’tyouwearaT-shirt?perhaps是提出建议的另一种方式
