1、吉姆已做完作业，他现在有空了。
2、他昨天收到一封信。
3、我父亲以前到过长城。
4、她还没有看过那部新电影。
5、她去过上海。
6、他这些天上哪儿去了？参考答案：一、单项选择。
1、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，正确答案是B。
2、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。
故2应选B。
3、C4、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”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时刻开始持续到现在的。
故4应选D。
5、C6、现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）。
故6应选C。
7、C8、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。
故8应选B。
9、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9的正确答案为B。
10、B11、现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。
故11的正确答案依次为：D。
12、B 13、A 14、C 15、A。
16、“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。
“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。
“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。
”故16的正确答案为A。
17、A 18、D 19、C 20、C二、句型转换。
