(三)易错点深度分析
1. 时空混淆:把时间点接for(for 2023)、时间段接since(since 3 months),牢记for接段,since接点。
2. 动词误用:非延续性动词直接连用,如He has left for 2 days,正确应为√He has been away for 2 days。
3. 时态搭配错:since后接句子用现在完成时(since she has left),正确应为since后接一般过去时(√since she left)。
4. 主句时态错:since/for搭配一般过去时(I lived here since 2019),主句必须用现在完成时(I have lived here since 2019)。
5. 固定搭配误解:since 3 months ago = for 3 months,二者可互换,均接现在完成时。
6. 瞬间动作答句错:how long提问时,不能用非延续性动词回答(I bought it for 1 week),需转化(I have had it for 1 week)。
二、中考题型分层练习(基础+提升+易错)
(一)基础题(1-8题,侧重用法区分)
1. My mother has taught in this school ______ 2015.
A. for B. since C. in D. on
答案:B 解析:2015是时间点,用since;for接时间段,in/on不用于现在完成时。
2. We have studied English together ______ three years.
A. for B. since C. at D. from
答案:A 解析:three years是时间段,用for,其余介词不搭配现在完成时表持续。
3. The little girl has been here ______ two years ago.
A. for B. since C. after D. before
答案:B 解析:two years ago是时间点,since+时间点ago=for+时间段,为固定替换。
4. —How long have you known Linda? —______ five years ago.
A. For B. Since C. In D. On
答案:B 解析:five years ago是时间点,how long提问,since接时间点回答时长。
5. He has kept the storybook ______ a week. He needs to return it.
A. for B. since C. at D. with
答案:A 解析:a week是时间段,且borrow已转化为延续性动词keep,直接用for。
6. They have lived in Guangzhou ______ they were born.
A. for B. since C. when D. as
答案:B 解析:后接过去时完整句子(they were born),只能用since表“自从……以来”。
7. The shop has been open ______ 8 o’clock this morning.
A. in B. for C. since D. on
答案:C 解析:8 o’clock this morning是时间点,open此处为形容词(be open表延续),用since。
8. We haven’t eaten anything ______ this morning.
A. for B. since C. at D. by
答案:B 解析:this morning是时间点,表“从今早开始就没吃东西”,用since。
(二)提升题(9-12题,侧重动词转化)
9. My father ______ the chess club since 2022. He loves playing chess.
A. joined B. has joined C. is in D. has been in
答案:D 解析:since 2022用现在完成时;join是非延续性动词,需转化为be in。
10. The movie ______ for ten minutes when we got to the cinema.
A. has been on B. had been on C. has started D. had started
答案:B 解析:start是非延续性动词,转化为be on;“到电影院”是过去时,“电影开始”在其之前,用过去完成时。
11. She ______ from China for 3 years. She misses her family very much.
A. has been away B. has left C. left D. is away
答案:A 解析:for 3 years表持续,leave转化为be away,用现在完成时。
12. —How long ______ you ______ this computer? —For about five years.
A. did; buy B. have; bought C. have; had D. will; buy
答案:C 解析:how long提问时长,buy转化为延续性动词have,用现在完成时。
(三)易错题(13-15题,侧重综合辨析)
13. Which of the following sentences is CORRECT?
A. He has borrowed the magazine for two weeks.
B. The meeting has finished since 9 a.m.
C. My grandparents have been married for 50 years.
D. She has left Beijing since 2020.
答案:C 解析:A borrow→keep;B finish→be over,且since接时间点不能与完成时表持续连用;D leave→be away from。
14. He ______ a teacher ______ he came to this small village.
A. has been; since B. is; because C. was; when D. has become; since
答案:A 解析:since后接过去时句子,主句用现在完成时;become是非延续性动词,转化为be。
15. —Why don’t you see the film with me? —I ______ it already. I ______ it for three days.
A. saw; have seen B. have seen; have had C. saw; saw D. have seen; have seen
答案:B 解析:第一空already用现在完成时表“已经看了”;第二空for three days表持续,see(非延续)转化为have(表持有看的经历/影片)。
