3. 语法 现在完成时
I. 用法
（1）现在完成时表示过去发生的动作对现在的影响
I have studied English. 表示I know a little English.
He has already come back. 表示He is here now.
常与already, yet, just, recently, ever, never, before等表示不确定时间的时间状语连用。
（2）现在完成时表示从过去一直持续到现在的动作或状态。
She has been ill for 3 days.
He has worked in the bank since 1990.
此时，句中谓语动词通常是延续性动词，且常与表示一段时间的时间状语连用。如：these days, all this year, recently, for ＋时间段以及since＋时间点等等。
II. 构成：have / has ＋动词过去分词
（1）has用于主语是第三人称单数，have用于其它人称
（2）动词的过去分词构成分为规则动词和不规则动词。规则动词在词尾加ed，其规则与过去式一样。不规则动词要记住。例如：take－taken, go－gone等。
III. 肯定式、否定式和疑问式
I have received a special gift.
I have not received any special gift.
I have never received any special gift.
Have you received any special gift? Yes, I have. / No, I haven’t.
He has ever played golf.
He has not played golf.
He has never played golf.
Has he ever played golf? Yes, he has. / No, he hasn’t.
IV. have been （to）和have gone（to）的区别：
“have been （to）”指“去过某地”，说话时此人已经不在那里，已经回来、侧重指经历。I have been to America. 我去过美国。
“have gone （to）”指“已经去了某地”，说话时此人在那里，或可能在路上，反正不在这里。He has gone to America. 他已经去了美国。
V. 延续性动词和瞬间动词
有延续性的动词可以和表示一段时间的时间状语连用。He has worked in the bank for 5 years. work 是延续性动词，可以和for 5 years连用。
而瞬间动词不可以和表示一段时间的时间状语连用。如果要表示其延续，可以用be动词。例如，不可以说He has come for 2 hours. come是瞬间动词。可以说He has been here for 2 hours. 他在这里呆了两个小时。
VI. 一般过去时，现在完成进行时和现在完成时的区别
一般过去时只表示过去的一个动作或状态，和现在不发生联系。现在完成时是用一个过去的动作说明现在的情况。
He lived in Beijing in 2000. 只说明他2000年住在北京，他目前住在哪里并不清楚。
He has lived in Beijing since 2000.
说明他自从2000年就住在北京，他目前还住在北京。
现在完成时和现在完成进行时都可以表示“从过去开始一直持续到现在”这一概念，有时两者可以互相代用，但前者多用于口语。在含义上如着重表示动作的结果时，多用现在完成时；如着重表示动作一直在进行，即动作的延续性或者动作仍然继续下去时，则多用现在完成进行时。如：
a. I have written six letters since breakfast.
从吃早饭到现在我写了六封信。
I have been writing letters since breakfast.
从吃早饭到现在我一直在写信。
b. I have read this book.
我读过这本书。
I have been reading this book.
我一直在读这本书。
练习：
I have already finished my homework . 已经
He has not finished his homework yet. 还没
My mom has just come back .刚刚
We have been very busy recently. 最近
I have ever seen this movie. 曾经
He has never read t
