学习、复习英语，先从时态开始吧！
现在完成时用于过去发生的动作或状态与现在的联系，包括对现在的影响、造成的结果以及动作的持续等。
1. 现在完成时的构成
①肯定句
句型：主语（第三人称单数以外的人称） Have done（动词过去分词）
主语（第三人称单数） has done（动词过去分词）
He's gone shopping.他去买东西了。
I've never been to Paris.我从未到过巴黎。
②否定句
句型：主语 have/has not done(过去分词)
I haven't seen him for a long time.我已经很久没见到他了。
He hansn’t finished his homework so far.到目前为止他还没有完成作业。
③一般疑问句
句型： Have/Has 主语 done( 过去分词)?
回答方式：肯：Yes，主语 have/has.
否：No，主语 have/has not.
Have you done it? —Yes，I have./No，I haven't.你做这件事了吗? ——是的，我做完了。/不，我没有。
Have you ever been to India? —Yes，I have./No，I haven't.你去过印度吗? ——是的，我去过。/不，我没去过。
Have you met your new neighbors? —Not so far.你见过你的新邻居没有? ——至今还没有。
④特殊疑问句
句型：疑问代词/疑问副词 have/has 主语 done(过去分词)?
Where have you been all this while? 这一阵子你在哪里?
What has she been busy with recently? 最近她在忙什么?
现在完成时的用法
1.表示结束、结果
现在完成时表示一个过去发生并结束的动作对现在产生的影响。这一类情况可以细分为下述两种情况：
①表示开始于过去的动作刚刚结束。常和already（已经），just（刚刚），now（现在），yet（迄今、还），not...yet（还没有）等连用：
I've already read that book.我已经读过那本书。
You're too late；the train has just left.你来得太完了，火车刚开走。
②表示过去动作的结果，现在仍残留着；一般不用时间状语：
It has just snowed.刚刚下过雪。（地上有积雪）
I have lost my watch.我把手表丢了。（现在仍未找到）
The concert has started. We have to look for our seats in the dark.音乐会已经开始了，我们得在黑暗中找座位。
The president's sudden death has left the country leaderless.总统突然去世，使该国处于无领袖状态。
2.表示继续
表示过去已经开始，持续到现在，仍要继续下去的动作或状态。往往和表示一段时间包括现在时间在内的状语连用，如today（今天），this week/month（本周/月），lately（最近），recently（最近），these days（这些日子），in the past few years（在过去的几年里），since（从……以来），since yesterday（从昨天以来），for a long time（很长时间），for a month/several years（一个月/几年），so far（迄今为止），up to now（直到现在），till/until now（直到现在）等：
He's known me for over twenty years.他和我相识已20多年了。
Has he studied French very long? 他学习法语很久了吗?
How long have you studied English? 你学英语多久了? （现在仍在学）
Up to now/Until now we've had no problems.直到现在为止，我们没有碰到任何问题。
3.表示经历和经验
表示从过去到现在之间经历过的事情。常和often（常常），never（从来没有），ever（曾经），once（一次），twice（两次），three times（三次），before（在……之前），since（自……以来）等连用：
Haven't I seen you before? 我以前见过你吧?
He has known both grief and happiness.悲伤和欢乐的滋味他都尝过。
We have not been to the cinema recently.我们最近没有去过电影院。
I have not seen that film yet.我还没有看过那部电影。
Her husband died ten years ago，but she has since remarried.她丈夫10年前去世，她后来又嫁人了。
I've read the novel twice.这部小说我看了两遍。
I've never been so annoyed in all my life!（=I was extremely annoyed）我这一生从没有这样恼火过!
4.用于状语从句
在时间或条件状语从句中，通常用现在完成时代替将来完成时，表示将来某一时刻前业已完成的动作：
Tell me what you think of the book when you've read it.你看完这本书后，告诉我你的想法。
We'll start at2 o'clock pm if it has stopped raining by then.我们将于下午2点开始，如果那时雨停了的话。
关于现在完成时用法的补充说明
1.关于短暂动作动词的用法
终止性动词（亦称点动词）如come（来），go（去），leave（离开），buy（买），borrow（借），join（参加），die（去世），marry（结婚），lose（失去），begin（开始），stop（停止），get up（起床）等表示的动作有一个终点，到了终点就不再延续。也就是说，此类动词只表示短暂的动作，因此不能与表示延续的时间状语连用：
不可以说：I've left New York for three days.
可以说：I've been away from New York for three days.（这时需要 使用be动词来表示延续的状态）
可以说：I left New York three days ago.我是3天前离开纽约的。
如果现在完成时的谓语动词是持续较短的动态动词（点动词），通常用否定结构；在这种情况下可以和表示一段时间的短语连用。因为点动词的这种否定结构构成一种状态，而这一状态是可以持续的：
They haven't written to me for3years.他们有3年没有给我写信了。
She hasn't left home for several days.她已有几天没有出门了。（表示“足不出户”这一状态）
They haven't visited us since2000.自2000年以来他们就没有拜访过我们。
表示短暂动作的动词用于完成时，通常表示目前的结果：
She's recovered from her illness.她已经痊愈。（含义是：目前状况良好）
I must go back；I've left（=forgotten to bring）my car keys（be-hind）.我必须回去，我忘了带汽车钥匙。（含义是：我现在开不了汽车门。）
English has borrowed words from many languages.英语借用了很多其他语言的词汇。（含义是：仍会借用其他语言的词汇。）
动词的过去分词的构成：
规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。
(1)一般动词，在词尾直接加“-ed ”。（然而要注意的是，过去分词并不是过去式）
work---worked---worked, visit---visited---visited
(2)以不发音的“e”结尾的动词，只在词尾加“d ”。
live---lived---lived
(3)以“辅音字母 y ”结尾的动词，将"y"变为"i"，再加“-ed”。
study—studied—studied, cry—cried—cried, try—tried—tried, fry—fried—fried.
(4)重读闭音节结尾，末尾只有一个辅音字母（r、y、x除外），先双写该辅音字母，再加“-ed”。
stop—stopped—stopped,drop—dropped—dropped
特例：有两类动词本身应该直接加“ed”，但由于历史习惯，依旧要双写最后一个字母，再加“ed”。以“元音字母 l”非重读结尾的规则动词变过去分词也要双写“l",再加“ed”。例如cancel→cancelled，dial→dialled。另外还有一些以非重读闭音节结尾的规则动词变过去分词也要双写最后一个辅音字母,再加“ed”。例如：kidnap→kidnapped，worship→worshipped。而上述两种情况在美国一般却直接加“ed”。
(5)以c结尾的动词，要变c为ck，再加“-ed”。
picnic→picnicked，traffic→trafficked
注：这样做主要是为了避免变化后其原型尾音/k/变成/s/。根据英文的拼写规则，c在字母e、i、y之前均发/s/，其他情况下均发/k/。如果直接加“ed”的话，trafficed将会读成/'træfɪsɪd/，而不读/'træfɪkt/。
