三、新课讲解
（一）现在完成时的构成
现在完成时由“助动词have/has+动词的过去分词”构成。现以动词work为例，将其肯定式、否定式、疑问式及简略答语列表如下：
肯定式 否定式 I/You have worked.He/She/It has worked.We/You/They have worked. I/You have not worked.He/She/It has not worked.We/You/They have not worked. 疑问式 简略答语 Have I/you worked Has he/she/it worked Have we/you/they worked Yes, you/I have.Yes, he/she/it has.Yes, you/we/they have. No, you/I have not.No, he/she/it has not. No, you/we/they have not.
【友情提示】规则动词的过去分词的构成与过去式相同。不规则动词的过去分词则要特殊记忆。have not常简缩为haven't，has not常简缩为hasn't。
（二）现在完成时的用法
1. 表示过去发生或已经完成的某一动作对现在造成的影响或结果。
e. g. -Have you had your lunch yet 你吃午饭了吗？
-Yes, I have. I've just had it. 是的，我刚吃过。
I have already posted the photos. 我已经把这些照片寄出去了。（这些照片已不在我这里了）
I have already seen the film. 我已经看过这部电影了。（了解了电影的内容）
2. 表示过去已经开始，持续到现在的动作或状态，可以和表示从过去某一时刻延续到现在包括现在在内的一段时间连用。表示持续动作状态的动词多是延续性动词。
e. g. We have known each other for 3 years.我们彼此已经认识三年了。
I've been at this school for over 2 years.我已经在这所学校呆了两年多了。
They have lived here since 1996.他们自从1996年就居住在这里了。
How long have you taught at this school 你在这所学校教书有多久了？
She has taught us since I came to this school.自从我来这所学校她就教我们。
（三）与现在完成时连用的常用副词
现在完成时常与already(已经），ever（曾经），never（从来不），just（刚刚），before（以前），yet（已经；仍然）等副词连用。
e. g. Have you ever made dumplings 你包过饺子吗？
I've just lost my English book.我刚刚把我的英语书弄丢了。
I've never been to that farm before.我以前从未去过那家农场。
I haven't learned the text yet. 我还没有学那篇课文。
（四）现在完成时态中应注意的问题
1. 点动词与延续性动词的区别
(1)所谓点动词是指含有终止或短暂意义的动词。如：begin, end, die, buy, borrow, come, arrive, join, marry等动词。它们通常不与表示一段时间的状语连用。
e. g. I have bought a book.我买了一本书。
I've had this book for three weeks.这本书我已经买了三个星期了。
(2)某些非延续性动词可以与since连用，表示重复的动作或状态。
e. g. I have met her often since I moved here.自从我搬到这儿，我经常遇见她。
They have gone fishing five times since last spring.自从去年春天以来，他们已钓了5次鱼了。
(3)有些非延续性动词的现在完成时在否定结构中可以与since或for短语连用。
e. g. He has never touched beer for a whole week.他整个星期都滴酒未沾。
I haven’t bought anything for a year.一年来我什么都没买。
2. has been to和has gone to的区别
has been to表示“曾经去过”，说明所提及的对象已回到说话地点。
has gone to表示“去……”，说明所提及的对象不在说话地点。
e. g. I've been to Beijing for many times. 我到过北京很多次了。
Tom has gone to Beijing and will come back next week.汤姆已到北京去了，下星期才回来。
