We haven’t seen you recently. 最近我们没有见到你。
They have been away for two years. 他们离开已经两年了。
She has been with us since M
since 后接时间点，如 1993，last term, yesterday, the time I got there
Exercise: I. Fill in the blanks with the proper form. 1. I____ already ____ (see) the film. I ________ (see) it last week. 2. _____ he ____ (finish) his work today? Not yet. 3. My father ____ just ____ (come) back from work. He is tired now. 4. Where’s Li Ming ? He __________ (go) to the teacher’s office. 5. I __________ (work) here since I ______ (move) here in 1999.
2）表示短暂意义的动词如 arrive, leave, borrow, buy, begin, start, die 等，在完成时当中不能 和表示一段时间的状语连用，因为它们表示的动作不可能持续。因此，不能说：
He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 以上三句话可以改为： He has been here for 2 weeks. The old man has ______ _______ for 4 months. They have _____ _____ only for 5 minutes 2）have (has) been 和 have (has) gone 的区别：表示“曾到过某地”要用 “have (has) been”; 表 示“已经去某地”要用 “have (has) gone”。试比较： Where has he been? 他刚才到哪里去了？（已经回来了） Where has he gone? 他上哪儿去了？（人不在） They have been to Canada. 他们到过加拿大。（现在已经不在加拿大） They have gone to Canada. 他们到加拿大去了。（可能在路上和已经到加拿大）. 3）现在完成时不能和表示过去的时间状语连用，如 yesterday, last year, in 1976, two days ago, just now, when I came in，但可以和 already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never 等连用。例如： She has already come. 她已经来了。 I haven’t read it yet. 我还没读过这个。 I have met him before. 我从前曾见过他。 Ma Hong has always been a good student. 马红一直是个好学生。 I have often seen him in the street. 我经常在街上看见他。 They have never been to Yan’an. 他们从未去过延安。 I haven't seen him lately. 我近来没看到他。
Yes, he has. No, he hasn’t.
（2）用法：
1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该
动作或状态对现在的结果或影响。
My daughter has just gone out. 我女儿刚出去。
I’m sure we’ve met before. 我肯定我们以前见过面。
