2、d the situation What do you think is happening in the picture?Listening objective Listen to the story,then tell me:What is the writers carpet made of?Key point现在完成时和现在完成进行时现在完成时 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 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
3、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 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 He 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 现在完成进行时 即在现在完成时的基础上，强调
4、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)这两件事中，哪件还在进行，就能改哪个。We have been learning English for ten years.总结 现在完成时/现在完成进行时 现在完成时功能大而全，但系混淆 现在完成进行时功能小，但不易混淆 使用原则：如果能用现在完成进行时，就用，这样不易混淆。Exercises：1、Alicia _(p

6、+just +done 时间间隔不长 already 已经 ever 曾经 never 从不 since+时间点 自从。for+时间段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 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 对于第二
7、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 have learned English for ten years.我们学英语已经有十年了。（现在和以后继续学）We learned English.我们曾经学过英语。（现在不学了）Text We have just moved into a new house and I have been working hard all morning.现在完成进行时的时间状语：all+表示时间的词语 all morning,all day,all week for,since I have been trying to get m
