Maybe they _whats happened to him . . knew . have known . must know,简析：现在完成时主要强调过去发生的动作对现在造成的影响，或过去发生的动作还未结束，一直持续到现在或将来，重点在于对现在的影响。这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。故上两侧根据上下文分析、推理

24、，正确答案是。,考点二：考查时间状语 例1. He has _ been to Shanghai , has he ? . already .never .ever 例2. Have you met Mr Li _？ . now . ago .before 例3.

We _ Xiao Li since she was a little girl . . know . had known . have known 例7. Brave Heart is a very nice film .I_ it twice .

26、. will see . have seen . saw,_B_,A,简析：现在完成时的时间状语常有如下四类： 现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。 现在完成时常与recently（近来），so far（到目前为止），in the past/“last + 一段时间”ever since(自以来）, since then（自那以后）等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或某一时刻开始持续到现在的。 现在完成时时常与“for

27、+时间段或since +过去时间点”连用（含从句，从句过去时）。 现在完成时还与once（一次），twice（两次），three times（三次），several times（几次）等表示重复次数的词语连用。,考点三：考查与一般过去时的区别 例1.These farmers have been to the United States .Really ? When _ there ? . will they go . did they go . do they go 例2._ you _ your homework yet ? Yes . I _ it a moment ago . . Di

28、d ; do ; finished B.Have ; done ; finished . Have ; done ; have finished,简析：现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago等）连用。故例、的正确答案皆为B。,B,B,考点四：考查延续性动词的用法 例1.
