12、词 +其他 一般 Have/Has+主语+过去分词+ 疑问句：？ 肯定答语: Yes, 主格代词+have/has. 否定答语: No, 主格代词+havent/hasnt.,动词过去分词的变化形式大部分与动词过去式形式相同，但是不规则动词的变化形式没有规律，需要记忆，比如：,see-saw-seen; be-was, were-been eat-ate-eaten; break-broke-broken go-went-gone; take-took-taken send-sent-sent; find-found-found make-made-made; have-had-had,1.
13、表示动作到现在为止已经完成或刚刚完成。 I have finished my work. We have set up many new factories. 2. 动作发生在过去，强调对现在的结果、 影响等。 Have you ever seen the film “Harry Potter”? Ive spent 3 years in the countryside.,现在完成时-用法,4. 现在完成时可以用在条件或时间状语从句中，表示将来某个时刻之前已经完成的动作。,Ill go home as soon as I have finished my homework. Please le
14、nd me that book if you have finished reading it.,already 已经，常用于肯定句中。一般置于助动词have/has之后，过去分词之前，但也可以放在句末。 我已经看过这部电影了。 I have already seen the film. 我已经解决了这个问题。 I have already solved this problem. 我已经做完家庭作业了。 I have finished my homework already.,现在完成时-与already连用,yet，在现在完成时句型中常置于句末。 1) 已经，常用在疑问句中。 琳达已看过这
15、本书了吗? Has Linda read the book yet? 你完成家庭作业了吗？ Have you finished your homework yet? 2) 还，仍然，常用于否定句和疑问句。 他还未开始工作。 He has not begun to work yet.,现在完成时-与yet连用,just 刚刚，常用于肯定句中。一般置于助动词have/has之后，过去分词之前。 我刚吃过午饭。 I have just finished lunch. 我们刚刚听说她的婚讯。 We have just heard of her marriage.,现在完成时-与just连用,同学们要注意现在完成时与一般过去时的区别。虽然这两个时态都和过去发生的事情有关，但是现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。如：,现在完成时与一般过去时,I went
