现在完成进行时讲解与专练.doc

现在完成进行时1 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 havent.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 hasnt.4 现在完成时的用法1） 在强调指出动作还未结束，还要继续下去。如：Ive been reading this book for two hours，but I havent finished it. 这本书我已读了两个小时了，但我还没读完。Ive 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。Weve 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：Weve been living here for ten years.Weve 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：Theyve known each other since 1970.自从1970年起他们就相互认识了。练习:1.
