Book 8 Unit 5 GrammarThe present perfect continuous tense----如今完成进展时1 定义: 一般表示动作从过去某一时间可是一直延续到如今，如今这个动作可能刚刚终止，也可能仍然在进展着。
2 如今完成进展时的构成:如今完成进展时是由“have/has+been+动词的如今分词〞构成3 如今完成进展时的根本句型：肯定式have \ has been V.ing疑问式Have \ Has sb. been V.ing？简单答复Yes，sb. have\ has . No，sb. haven't\ hasn't4 如今完成时的用法1）在强调指出动作还未完毕，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。
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〕如今完成进展时也可表示如今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 如今完成时和如今完成进展时的区别(1) 如今完成时的“已完成〞用法强调动作的完成，而如今完成进展时表示动作未完成。
试分析：I have read David Copperfield.〔已看完〕I have been reading the novel.〔未看完〕They have built an oil ship.〔已造成〕They have been building the oil ship.〔未造成〕(2) 在与表示一段时间的状语连用时，如今完成时的“未完成〞用法和如今完成时都表示动作过程的持续性，但用如今完成时更强调动作延续时间的长久。
