1、1【易错考点回顾易错考点回顾】现在完成时与其它时态的辨析现在完成时与其它时态的辨析【易错点睛易错点睛】在现在完成时的考查中，以现在完成时与一般过去时的辨析较为常见。两者有如下区别。1. 两者都表示在过去发生的动作。但现在完成时侧重过去的动作对现在造成的影响。而一般过去时侧重于表过去的动作，与现在无关。如：Yesterday I went to the zoo. 昨天我去了动物园。 （仅说明昨天去了动物园，与现在无关）Li Lei has read the book. 李磊已看过那本书。 （说明李磊了解那本书的内容）2. 连用的时间状语不同：与现在完成时连用的时间状语有 already, yet
2、, still, just, so far, in the last/past, before, ever, never, since 或 for 引出的时间等。而一般过去时则常与 ago, yesterday, last, in 2000, just now 等连用。Have you ever picked flowers or steeped on the grass in a park? 你们曾在公园里摘过花或踩过草地吗？Father bought that watch ten years ago. 爸爸十年前买了那块手表。I have never seen the film befor
3、e. 我以前从没看过这部影片。一招致胜时态现在完成时一般过去时意义过去的动作对现在有影响过去的动作时间状语since, since then, for+一段时间, so far, in the last/pastago, yesterday, last, just now, in +过去年份,【易错考点回顾易错考点回顾】1. _ you _ your homework yet?Yes. I _ it a moment ago.A. Did; do; finished B. Have; done; finishedC. Have; done; have finished D. Will; do;
4、 finish2【错因分析】题干中有个 yet，这是现在完成时常用的副词，如果考生忽视了这一点，就容易错选，而答语中有个 a moment ago，这是一般过去时的常用时间状语，所以在做时态题的时候，需把握住题干中的时间状语，否则容易错选。【思路点拨】把握住现在完成时的使用特点，抓住题干中的关键词和时间状语即可快速的判断出正确答案。【正确答案】正确答案为 B。句意：你做完作业了吗？是的。我刚才做完的。根据问句中的 yet 可知应该用现在完成时态，根据答语中时间状语 a moment ago 可知应该用一般过去时。故选 B。【中考链接中考链接】1. （2017 北京中考）Lily is my c
5、lassmate. We _ each other since she came to our school.A. know B. knew C. have known D. will know【答案】C解析：考查动词的时态。since 引导时间状语从句时，从句用一般过去时，主句应用现在完成时。故选 C。2. （2018 青岛）Its time to work now.OK, Ill wake Carl up. He _ for an hour. A. has fallen asleep B. has been asleep C. fell asleep D. falls asleep【答案】
6、B解析：根据 for an hour 可知，这是一个表示一段时间的时间状语，通常用于现在完成时中，并且动词应用延续性动词，而 fall asleep 是瞬时性动词，在完成时中应变成持续性的状态，故选 B。3. （2017 常德）I _ Anna since three years ago. A. knew B. know C. have known答案：C解析：根据句中的时间状语 since three years ago 可知要用现在完成时，其结构是have/has+过去分词，故选 C。3【闯关提分训练闯关提分训练】现在完成时与其它时态的辨析现在完成时与其它时态的辨析1. _ you _ t
