.语法
现在完成进行时?
.【重难点分析】
1.?现在完成进行时
构成:
肯定句:主语?+?have?/?has?been?+?doing?
否定句:主语+have/has+not+been+doing?
一般疑问句:Have/Has+主语+been+doing??
现在完成进行时表达“某一动作从过去开始一直持续到现在,有可能还要持续下去”,现在完成进行时的句子中多用延续性动词,如:live,learn,study,work等。?
(1)?I?have?been?learning?English?for?ten?years.?我学英语已经十年了。
(2)?She?has?been?skating?for?four?hours.?到现在为止她滑冰已经有四个小时了。?
(3)?I?have?been?collecting?stamps?since?I?was?ten?years?old.?我从十岁起就一直在集邮。?
在这几个句子中,have和has是助动词,疑问形式需把助动词提前,否定形式在have或has后面加not,have?not和has?not可以分别缩写成havent和hasnt,如:?
(1)?Have?you?been?doing?your?homework?since?this?morning??从今天早晨起你就一直在写作业吧??
(2)?Has?he?been?writing?the?letters?to?his?friend??他是一直在给他的朋友写信吗??
(3)?I?havent?been?seeing?films?for?a?long?time.?我有很长时间没有看电影了。
?(表明没有看电影这个动作从过去一直持续到现在,还要继续持续下去。)?
现在完成进行时与现在完成时的区别:
(1)?现在完成时强调动作的完成,而现在完成进行时侧重的是动作的持续进行。?
如:?
I?have?read?a?book?about?birds.?(已经读完)?
I?have?been?reading?a?book?about?birds.?(一直都在读,现在还在读,有可能会继续读下去)?
(2)?两种时态都有延续性,?但现在完成时往往只说明一个事实,一种影响或结果,无感情色彩;现在完成进行时表示一个动作的延续、重复,有时有一定的感情色彩。?
如:?
She?has?been?singing?all?the?day.?她都唱了一整天了。(抱怨、厌烦)?
2.?since,?f
