1.-Where's Peter?
-He ( A ) to the library,but I'm not sure.
A may have gone B might go 请问:为什么选A而B是错误的?
答:might 是情态动词may的过去式,但是在表示“推测”判断时,意为:“或许,可能”,它们只是语气上的不同,后者比前者更没有把握,并不能表过时间的不同.要表示对过去的情况的判断用may/might have done sth.而may/might do sth.是对现在或将来情况的推测判断.
译:彼得在哪里?
A、他也许去图书馆了,不过我不是很肯定.
B、他可能要去图书馆,.
为什么选A不选B,清楚了吗?
2.-It's a long time since we last met.What about the two of us (C ) a drink this weekend?
- Sure.Let's call it a deal.
A to have B have C having D to be having
请问:为什么选C.ABD为什么不对
答:记住一个句型:what about (sb's/sb.) doing sth.用于征询对方的意见,译作:.怎么样?此题就非常简单了.about是介词,后跟动名词,排除AD(不定式).C.是谓语动词.
译:自从上次我们见以来,已经有很长一段时间了.这个周末我们俩去喝一杯怎么样?
当然好了.就这么定了.
注:动名词的逻辑主语用名词所有格(及物主代词),作宾语时,口语中常用名词普通格(人称代词的宾格)代替.如:Do you mind Tom's (Tom/ his/him) opening the door?
3.They ( D ) the plane.Perhaps they have been prevented from coming for some reasons.
A can have lost B may have lost C can have missed D may have missed
请问:为什么选D ,意思是什么 .ABC 错在哪?
答:本题考may和can的区别及miss 和lose的区别.
表示对过去情况的推测,肯定的用must have done sth.不是很肯定的用may/might have done sth.
否定的用can't have done sth.(不可能做过),can不能用于‘肯定’的推测,只能用于否定的.排除AC.
miss表是错过,没赶上,lose 表示 丢失.
译:他们也许没有赶上那班飞机.也许他们因为某些原因来不了了.
