备考现在完成时要点说明一、考查表示对现在造成了影响的过去动作动作虽然在过去(说话前)已经发生，但它所造成的结果或影响现在依然存在，且强调的是对现在所造成的结果或影响。有时与just, already, yet, recently, before, three times等时间状语连用，但不与when, yesterday, just now, in 1980, last year等表示明确的过去时间的状语连用。如：1. She has set a new record, that is, the sales of her latest book ________ 50 million. (福建)A. have reached B. has reachedC. are reaching D. had reached【分析】答案选A。由has set和that is(即，换句话说)可知，后句的谓语动词也应用现在完成时，排除C和D；又因主语the sales是复数，排除B。本句用现在完成时强调“已经达到5000万”之多这一结果。2. The price ________ but I doubt whether it will remain so. (全国卷)A. went down B. will go down C. has gone down D. was going down【分析】答案选C。后文(will remain so)暗示物价已经降下来了，且目前仍然低。3. —Who is Jerry Cooper?— ________ ? I saw you shaking hands with him at the meeting. (全国卷)A. Don’t you meet him yetB. Hadn’t you met him yetC. Didn’t you meet him yetD. Haven’t you met him yet【分析】答案选D。由I saw. . 可知meet发生在过去，且强调的是对现在的影响：你应当认识Jerry Cooper。4. — ________ my glasses? (全国卷)—Yes, I saw them on your bed a minute ago. A. Do you see B. Had you see C. Would you see D. Have you seen【分析】答案选D。重点是问对方“见过”眼镜的结果：现在知道眼镜在哪里。5. You don’t need to describe her. I ________ her several times. ()A. had met B. have met C. met D. meet【分析】答案选B。强调的是见过几次的结果：我已经对她了解了。注：现在完成时强调过去动作对现在的影响，而一般过去时只表明在过去发生过某事。如：When I was at college I three foreign languages, but I all except a few words of each. (全国卷)A. spoke; had forgottenB. spoke; have forgottenC. had spoken; had forgottenD. had spoken; have forgotten【分析】答案选B。前者强调在过去发生的事，后者强调“忘记”的结果。[1][2]下一页 说明:引用此文请注明出处,并请保留该文章链接地址,谢谢~~二、考查表示从过去某一时刻开始一直延续到现在的动作或状态非否定句中的谓语动词一定是延续性动词，常与表示一段时间的状语连用，如“since+时间点”，“for+时间段”，how long, ever since, so far, in the last / past few years, up to now, till now, it is the first time that…等。如：1.
