现在完成进行时定义:现在完成进行时表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去。2 现在完成进行时的构成:现在完成进行时是由“have/has+been+动词的现在分词”构成 3 现在完成进行时的基本句型 肯定式
I/We have been working.疑问式
Have you been working？
简略回答
Yes，I/we have.No，I/we haven't.肯定式
He/She/It has been working.疑问式
Has he/she/it been working？
简略回答
Yes，he/she/it has.No，he/she/it hasn't.4 现在完成时的用法
1）在强调动作还未结束，还要继续下去。如：I've been reading this book for two hours，but I haven't finished it.这本书我已读了两个小时了，但我还没读完。I've read this book.我已读完这本书了。2）强调动作延续时间的长久或带感情色彩。
She has always been working like that.她一贯是这样工作的。3）现在完成进行时也可表示现在以前这段时间反复发生的事情。We've been seeing quite a lot of each other recently.最近我们经常见面。5 现在完成时和现在完成进行时的区别
1）现在完成进行时更强调动作的延续性,它是现在完成时的强调形式。试比较： We've been living here for ten years.We've lived here for ten years.我们在这儿已经住了十年了。
2）在不用时间状语的情况下，现在完成进行时表示动作仍在进行。而现在完成时则表示动作在过去已结束。如：
The students have been preparing for the exam.（还在进行）学生们一直在准备考试。The students have prepared for the exam.（已经结束）学生们为考试作了准备。
3）有些表示状态，感情，感觉的动词如：have，exist，like，hate，hear，know，sound等动词不能用于现在完成进行时，但可用于现在完成时。如：
They've known each other since 1970.自从1970年起他们就相互认识了。练习: 1.— I’m sure Andrew will win the first prize in the final.— I think so.He ________ for it for months.)A.is preparing B.was preparing
