【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：

YesterdayI 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)

LiLei 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, 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。

Haveyou 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?

Fatherbought that watch ten years ago.爸爸十年前买了那块手表。

Ihave never seen the film before.我以前从没看过这部影片。

【易错考点回顾】

1.—______ you ______ your homework yet?

—Yes.I ______ it a moment ago.

A.Did; do; finished B. Have; done; finished

C.Have; done; have finished D. Will; do; finish

【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amoment 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amoment ago可知应该用一般过去时。故选B。
