篇3：现在完成时的用法
1. 现在完成时的定义
现在完成时既可表示过去发生的动作对现在所造成的结果或影响(此时通常连用的时间状语有already, yet, just, ever, before)，也可表示动作从过去某时间开始，一直持续到现在，并且还有可能持续下去(此时通常连用的时间状语有this month / week / year, these days, recently / lately, in the past few + 时间段, since +时间点, for + 时间段)。如：
I have just finished my work. 我把工作做完。
Have you ever been to Beijing? 你曾经去过北京吗?
I have lived for ten years. 我在这儿住了十年了。
We have studied here since 2003. 我们自来就在这儿读书了。
2. 现在完成时的结构
现在完成时由“have / has + 过去分词”构成。
3. 现在完成时的应用
(1) 非持续性动词go, come, leave, borrow, buy, die, join的完成时的肯定式不能与时间段连用，若要接用时间段状语，则应换成相应的持续动词或状态动词。如：
He has left. 他走了。
He has been away for an hour. 他走了一个小时了。
Can I borrow that book? 我可以借那本书吗?
How long can I keep the book? 这本书我可借多久?
注意：非持续性动词的否定完成时可与时间段状语连用。如：
He has not borrowed the book since then. 从此以后，他再也没有借这本书了。
(2) have / has been to 表示曾经去过某地，但现在不在那儿;have / has gone to表示现在已去某地，现在不在这儿。如：
He has been to Canada, but now he is working in our company. 他去过加拿大，现在在我们公司工作。
Mr. Li is not at home. He has gone to Shanghai. 李先生不在家，他去上海了。
(3) 完成时的肯定式常用already，而否定式和疑问句常用yet，但若already用于疑问句时，表示一种出乎意外的惊讶。如：
Have you read it already? 你就看完了?
4. 现在完成时与其他时态的区别
(1) 现在完成时与一般过去时的区别：现在完成时强调动作的结果或对现在的影响，属于现在时的范畴;一般过去时强调动作所发生的时间，属于过去时的范畴。因此，过去时需跟过去时间连用或有表过去时间的上下文连用，而现在完成时不能与过去时间连用。如：
I read the book two weeks ago. 我两周前读了这本书。
I have read the book for two weeks. 这本书我读过两周了。(from www.hxen.com)
(2) 现在完成时与现在进行时：现在完成时强调动作持续到现在或刚结束;而现在进行时只强调目前的状态。如：
They have talked for about two hours. 他们谈了大约两个小时。(强调动作的持续)
They are talking. 他们在谈话。 (强调目前的状态)
篇4：现在完成时的用法
1.表示过去已经开始,持续到现在的动作或状态往往和表示一段时间的状语连用.for+一段时间,since+一段时间 How long..
I have known him for ten years.
For 和since要用延续性动词leave/go- be away,come-be here/be in,buy- have,borrow-keep,join-be in/a member of,die-be dead,begin- be on,finish- be over
2.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.常用的时间状语：already,so far,never,just,before,recently,
I have lost my key.(说明过去某时丢的,现在还未找到.)
3.表示从过去某一时间到说话时这段时间中反复发生的动作,常用often,always,seldom,never等连用.注意与一般现在时的区别.
We have been to the Summer Palace twice.
4. 表示次数.
5.Have been to /have gone to
6.经典句子I haven’ t seen you for a long time.Where have you been?I have been to Shanghai.How many times have you been there?I have been there twice
7.现在完成时与一般过去时的区别
1)侧重点不同：现在完成时侧重于过去的动作对现在造成的影响,而一般过去时侧重于表示过去的动作与现在无关.
2)连用的时间状语不同.
3)询问某事过去发生的具体时间,地点时必须用一般过去时.现在完成时不可与表示过去的时间状语连用.
8.现在完成时需要注意的几点
1)由since引导的时间状语从句主句通常用现在完成时.
2)句型It is/ has been+ 时间段 + since
3)表示某人所作过的用This is the….that….结构,后面的句子要用完成时.
This is the first time that I have been here.
4)非延续性动词的否定形式可以表示状态的延续.可与for,since连用.
5) age /before的区别
ago为副词,表示从现在算起的过去某时间以前,用于名词词组 + ago .ago所在句子的谓语动词一般为过去时,它不可以单独使用,也不可以用做连词.
before为副词时,表示从过去的某一时刻或某一事件算起的过去某时间以前,用现在完成时.它还可以单独使用,也可以用做连词,此时后接单词,词组或句子.

我以前见过成龙。
(含义：我对他有所了解了，现在能够谈谈他的情况了。)

模仿造句：
1.因此，我们以前参观莫斯科(Moscow)。
2.你弟弟去去印度(India)吗?
3.这些孩子从未用过电脑。
2.现在完成时，表示过去某种行为的结果对现在有直接的影响

篇8：英语中现在完成时的错误用法讲解

系表型have(has)been+表语
1.瞬间动词，不能与表示时间长度的状语连用
他们已到达这里两小时了。
×They has arrived here for 2 hours.
√They has been here for 2 hours since she got here.

√They arrived here yesterday afternoon.
我在1995年就已经毕业了。
×I have graduated in 1995.
√I graduated in 1995.

√I met Xiao Li in Shanghai.
他在家乡就已把发型改了。
×He has changed his hairstyle in her hometown.

篇9：现在完成时的“完成用法”和“未完成用法”
作者：张新峰 苏仁 王小英
1.现在完成时的“完成用法”
现在完成时的“完成用法”指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。
例如：He has turned off the light.他已把灯关了。（动作结束于过去，但说明的是现在的情况--灯现在不亮了。）
现在完成时“完成用法”的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语（如：already，yet，before，recently等）、频度时间状语（如：never，ever，once等）、包括现在时刻在内的时间状语（如：this morning ／ month ／year．．．，today等）连用。
例如： Have you found your pen yet？你已找到你的钢笔了吗？
2．现在完成时的“未完成用法”
现在完成时的“未完成用法”指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。
例如：He has lived here since 1978．自从1978年以来，他一直住在这儿。（动作起始于1978年，一直住到现在，可能还要继续住下去。）
I have been in the army for more than 5 years．我在部队已经呆了五年多了。（动作开始于5年前，一直延续至今，有可能还要继续下去。）
此种用法的句中常需一个表示一段时间的状语（由since或for引导），或表示与现在时刻相连的时间状语（如：up to now，so far）等。
例如：I have heard nothing from him up to now．到目前为止我没有他的任何消息。
注意：（1）现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。
（2）现在完成时常见两种句型：
①主语＋have / has been＋for短语
②It is＋一段时间＋ since从句
例如：He has been in the League for three years．或It is three years since he joined the League． 他入团已三年了。
篇10：英语时态之现在完成时
结构
1) 肯定形式：S. have/has +动词的过去分词done +O.
2) 否定形式：S. have/has+ not+ 动词的过去分词done +O.
3) 疑问形式：Have/has+ S. + 动词的过去分词 done +O.
主要用法
1、过去发生并且已经完成的动作对现在造成的影响或导致的结果。这种状态下，already、just、never、ever、yet等副词常和谓语动词一起使用。如：
They have already come back from the museum.
She has already finished her homework.
2、过去发生的动作持续到现在，并可能持续下去。这种状态下，for和since作为标志性词语常和谓语动词一起使用，而且此时的谓语动词往往是持续性动词(如stay、keep、wait等)。如：
I have lived here for ten years.
He has kept the clavichord since thirty years ago.
3、从过去某一时间到说话时这段时间内反复发生的动作。这种状态下，表频度的副词(often、always、seldom、never等)和表次数的单词或短语(如once、twice、three times)常和谓语动词一起使用。如：
You have never listened to me like this before.
She has ever been to France.
They have visited the Summer Palace many times.
标志性词语
1、副词already、just、never、ever、yet等。如：
She hasn't arrived in Scotland yet.
They have just left for Shanghai.
2、for和since。for+一段时间，since+具体时间。如：
He has learned Italian for five months.
He has learned Italian since five months ago.
3、so far和up to/till now。表示“迄今为止”。如：
So far, no one has heard any news about her.
She has read fifty books up to now.
4、recently、lately等表示“最近;最新”的副词和形容词。如：
I've met her on several occasions recently.
He hasn't had enough sleep lately.
5、in the past/last+一段时间，表示“在过去的...时间里”。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。如：
I've tried many times, but there's no way.
He has been there at least twice.
句型转换
“have/has done”中的have/has是助动词，在进行句型转换中要注意不需要再另外借助助动词do/did/does，而是直接借用have/has。如：
肯定句：He has lived here for the last few years.
否定句：He hasn't lived here for the last few years.
一般疑问句：Has he lived here for the last few years?
划线提问：How long has he lived here? (划线部分为for the last few years)
