3、在完成时非常常用 但比较难是否学好现在进行时，事关五种时态的学习：过去完成时将来完成时现在完成进行时过去完成进行时将来完成进行时现在完成时非常常用 但比较难一、形式 have/has + done(过去分词)二、用法完成的含义？不要望文生义完成 现在全部完成 现在部分完成现在的之前（不管这事做没做完）只要站在现在的时间点回头看过去，不管这事做没做完 都可以用现在完成时一、形式他走了。He has left.（现在全部完成）我们学英语十年了。We have learned English for ten years.（现在部分完成） 以后还要继续学三、否定 疑问助动词+not助动词提前他走了。H

4、e has waited for three hours. 现在完成他现在的之前等了三个小时。他现在还在么？不一定结论：等完 没等完这句话容易发生歧义。具体情况可根据上下文判断。如果没有上下文呢？创造一个新时态现在完成进行时He has waited for three hours.现在完成进行时即在现在完成时的基础上，强调这事还没做完，还在进行。这个时态就弥补了现在完成时的缺陷公式：have /has+been+doing用法：发生在现在的之前，还在进行eg：He has left.(现在全部完成)We have learned English for ten years.(现在部分完成)这

7、just +d现在完成时和一般过去时的区别1、He has left.现在全部完成 可以换成一般过去时=He left.区别在于 看待事物的角度现完：站在现在看过去一过：站在过去看过去现在完成时和一般过去时的区别1、He has left.应用：如无明确要求，两种均可。如有要求，要根据看待事物的角度进行选择考试中，出现对现在有明确影响的，用现完 他离开了，所以现在我找不到他了He _,so I cant find him now. has left 他离开了两个小时。He _two hours ago. left应用：对于第二种情况，现在部分完成，不能换成一般过去时,因为二者意思完全不同We
