第二，现在完成时
(1)定义
现在完成时主要用来表达过去发生的行为对现在的影响或结果。比如：
I have already seen the film.
She has just had a bath.
(2)基本结构
现在完成时的句子结构一般是：
主语-have/has过去分词其他成分
比如：
We have already had lunch.
He has been away for a week.
(三)主要用途
1、表示过去和已经完成的动作对现在的影响或结果。这时，经常与谓语动词连用的副词有已经、刚刚、从来、曾经、还等。比如：
They have already come back from the museum.
She has already finished her homework.
2.意思是过去发生的动作一直延续到现在，可能还会继续。此时经常与谓语动词连用的符号词主要有for和since，此时的谓语动词往往是持续性动词(如stay、keep、wait等。).比如：
I have lived here for ten years.
He has kept the clavichord since thirty years ago.
3、表示从过去某个时间开始讲这段时间重复的动作。这时，频率副词如oft、always、less、never等。经常与谓语动词连用。
以及表示次数的单词或短语(如一次、两次、三次)。比如：
You have never listened to me like this before.
She has ever been to France.
They have visited the Summer Palace many times.
动词的过去分词
1、规则改变
其变化规律与动词一般过去式基本相同，主要是在词尾加-ed或-d。具体来说：
1) Add Ed directly. For example, I have worked and played.
2)在以不发音的e结尾的动词后加-d .如：lived，danced。
3)辅音字母加Y结尾的动词由Y改为I，再加-ed。如：学了，哭了。
4)以重读闭音节结尾的动词后，双写最后一个辅音字母，加-ed。例如停止和图案化。
2.不规则变化
如果结合动词的过去时，动词过去分词的不规则变化有一些相对规则的现象。比如：
1)AAA型。如：放放放；读读读。其中read的过去式与过去分词拼写相同，但发音与原形不同。ea不再读作[i]，而是读作[e]。
2)AAB型。如：beat beat beaten
3)ABB type. Such as: keep keeping keeping; Sit down.
4)ABC type. Such as: lying down; get drunk
5) abscisic acid type. Such as: running and running; come on
(5)象征性词语
1. Adverbs have, just, never, forever, not yet, etc. Such as:
She hasn't arrived in Scotland yet.
They have just left for Shanghai.
2、为且自。一段时间，从具体时间开始。比如：
He has learned Italian for five months.
He has learned Italian since five months ago.
3.到目前为止。意思是“到目前为止”。比如：
So far, no one has heard any news about her.
She has read fifty books up to now.
4.最近，最近等。意思是“最近；最新的副词和形容词。比如：
I've met her on several occasions recently.
He hasn't had enough sleep lately.
过去/持续一段时间，意思是“过去……”。比如：
In the past few years, new buildings have sprung up all over Beijing.
He had aged rapidly in the last few months.
6.次数。比如：
I've tried many times, but there's no way.
He has been there at least twice.
(6) Yes/Yes/No.
1. I have been there
意思是“我去过又回来了”。句子的主语在现场。比如：
They have been to Rome many times.
She has been to Shanghai more than once.
2. I went
意思是“一去不复返”。句子的主语不在现场。比如：
Jerry has gone to Hangzhou.
Mary has gone to Finland.
3. All the time
一直呆在某个地方。比如：
We have been in Beijing for five weeks.
They have been in China since 2012.
(7)瞬时动词和连续动词
所谓瞬时动词，主要是指一旦发生就立即结束的动作，也叫瞬时动词，如死、嫁、离等。而进行动词主要是指可以一直持续下去的动作，也叫进行动词，如learn、live、talk等。
这两种动词都可以用在现在完成时，但是瞬时动词不能和表示一段时间的时间状语连用。此时，就需要将瞬时动词改为相应的表示状态的动词或短语。比如：
He has been dead for ten years.
Correct. He's been dead for ten years.
She has married him since five years ago.
: She has been married to him since five years ago.
(8)句型转换
因为“have/has done”中的have/has是助动词，所以需要注意的是，在句型转换中不需要使用助动词do/did/does，而是直接借用have/has。比如：
He has lived here for the past few years.
He hasn't lived here in recent years.
Has he lived here for the past few years?
How long has he lived here? (The underlined parts are recent years)
