22、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。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

23、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 ,

24、 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”表示经“曾去过某地（但 现在已不在那儿）。”故1

25、6 的正确答案为 A。17、A 18、D 19、C 20、C二、句型转换。1、 has he? 2 、 How long 3 、died, has been dead4、 has been open 5 、 has been away 6 、joined ； ago7、It is, since 8 、 The bus has been here for ten minutes.三、汉译英。1、 Jim has finished doing his homework already. He is free now.2、 He received a letter yesterday.3、My father has been to the Great Wall before.4、She hasnt seen the new film yet.5、She has been to Shanghai.6、Where has he been these days ？
