中考英语语法丨现在完成时详解（附练习题及答案）
一.现在完成时的构成：
"have/ has+动词的过去分词”。
①肯定句主语+have/ has+动词的过去分词。Though he has read the book three times, he hopes to read it again.
尽管已经把这本书读了三遍，他仍希望再读一次。
②否定句:主语+have/ has+not+动词的过去分词。You haven't been here for a long time.
你已经很长时间没来这儿了。
③一般疑问句:Have/Has+主语+动词的过去分词? Have they finished the work yet?
他们已经完成这项工作了吗?
二.现在完成时的用法
(1)表示发生在过去的动作对现在仍有影响
My father has gone to Shanghai. (表示人不在这里了)我爸爸去上海了。
I have already had supper. (表示现在不饿了)我已经吃过晚饭了。
(2 )表示从过去开始一直延续到现在(可能延续下去)的动作或状态
He has lived here since 1970.
他自从1970年以来一直住在这里。
My brother has been a soldier for two years.我哥哥已经参军两年了。
提示：常与现在完成时连用的时间状语有alredy(已经),yet (还)，just (刚刚), never(从不),ever(曾经)，before (以前), recently（近来）, since then(从那时起)，since(自从),so far (到目前为止),for a long time（很长一段时间), in the past/last few years (在过/最近的几年里)等。
(3 )have/has gone to和have/has been to的区别：
①have/has gone to去了某地，不能与once, twice, three times等连用
②have/has been to去过某地，可以与once, twice，three times等连用
一Hello, may I speak to Tom?
你好，我可以和汤姆通话吗?
一Oh, sorry! He has gone to London
噢，抱歉!他去伦敦了。
Helen has been to Hong Kong.
海伦去过香港（以前去过香港,已从香港回来) 。
I have been to Bijing twice. ( have been to可与次数连用)我去过北京两次。练一练：
l（）scared of dogs ever since a dog hurt me when I was five years old.
A. will be
B. was
C. have been
D. would be
[解析]ever snce...意为“...以.”常用于现在完成时。现在完成时的构成为havehast动调的过去分词，故选C。
[答案]C
三. 现在完成时中短暂性动词怎样和表示一段时间的状语连用。
短暂性动词又叫终止性动词、瞬间动词或非延续性动词，只表示一时的动作,在肯定句式中不能与表示延续的时间状语连用。这类动词常用的有
go,come ,leave,find, buy, rrive,give,stop ,join, marry,die,pass away等。同学们如果对现在完成时理解不透彻，在使用时就会出现不少的错误。例如:“这本书我买了三个月了。”误译成“I have bought this book for three months.”。为了避免这类错误，我们在使用这类词时一定要学会并掌握以下“三个变化”。
1、谓语动词的变化：把短暂性动词变为延续性动词。例如:
leave →have( has) been away from
join→have( has) been( in)
buy→have( has) had
die→have( has) been dead
come( arrive)→have( has ) been here
borrow→have( has ) kept
begin to work→have(has) worked( studied)
open→have( has ) been open
get up→have( has )been up
put on→have( has )on
come back→have( has ) been back
marry →have( has) been married等。
例如:
①他来这里半小时了。
[误] He has come here for half an hour.
[正] He has been here for half an hour.
②他犹豫不决、沉默了一会儿。
[误] He hesitated and gave no reply for a while.
[正] He heitated and remained silent for a while.
2、时间状语的变化把表时间的状语“for...”变为“数词+时间名词ago"的短语形式。如：
他参军八年了。
[误]He has joined the Army for eight years.
[正]He has been in the Army for eight years.
[正] He joined the Army five years ago.
他离开济南五年了。
[ 误] He has left Jinan for five years.
[正] He has been away from Jinan for five years.
[ 正] He left Jinan five years ago.
3、句子模式的变化：可把句式变为"It is +时间+ since...”的句式。例如:
我爷爷已去世十多年了。
[误] My grandpa has died for more than ten years.
[正]My grandpa has been dead for more than ten years.
[ 正] My grandpa died more than ten years ago.
[ 正]It is more than ten years since our my grandpa died.
中华人民共和国成立多久了?七十一年了。
[误] How long was the People's Republic of China founded? It was founded for 71 years.
[正]How long is it since the People's Republic of China was founded? It is seventy-one years since it was founded.
练一练：将下列句子译为英语。
1.我兄弟入团两年了。
①_ _ __ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
②_ _ _ _ _ _ _ _ _ _ _ _ _ _
③_ _ _ _ _ _ _ _ _ _ _ _ _ _
④_ _ _ _ _ _ _ _ _ _ _ _ _ _
2. 我父亲去世已三年了。
①_ _ _ _ _ _ _ _ _ _ _ _ _ _
②_ _ _ _ _ _ _ _ _ _ _ _
③_ _ _ _ _ _ _ _ _ _ _ _ _
答案：
1. ①My brother has been in the Youth League for two years.
②My brother has been a League member for two years.
③My brother joined the Youth League two years ago.
④It is two years since my brother joined the Youth League.
2. ①My father has been dead for three years.
②My father died three years ago.
③It is three years since my father died.
四.怎样检验终止性动词？
英语中有些动词表示的行为是不能延续的,被称为终止性动词，也叫瞬间动词或非延续性动词。这类动词不能用于”现在完成时+for引导的“时间状语“这一结构中充任非否定谓语。例如:
那老人死了五个月了。
[误]The old man has died for five months.
[正]The old man has been dead for five months.
因为die是终止性动词，一个人从活着到死亡的变化是转瞬之间就完成的，不具有延续性，哪能延续五个月呢? 所以我们要把die 改为延续性动词be,表示存在
的状态。如果要用die来表达,我们就得改变时态和句型，比如我们可以将上例说成:
The old man died five months ago.或者:
It's five months since the old man died.
一个动词是不是属于终止性的，同学们往往确定不下来，而词典上一般又没有注明。那么，我们该怎样检验它呢?这里给大家介绍一个方法。
把需要检验的动词放到“现在完成时+ since引导的‘时间状语’”这一句型中充当肯定谓语。如果意思讲得通，就是延续性动词;讲不通，就是终止性动词。现在我们就把wear和put on拿来试试:
She has worn the green skirt since the day before yesterday.
(从前天到现在她一直穿着那件绿裙子。)讲得通，wear是延续性动词。She has put on the green skirt since the day before yesterday.
(从前天到现在她一直穿上那件绿裙子。)讲不通,put on是终止性动词。
练一练：
请试用上述方法判断下列句子的正误。
（）1. He has left Hangzhou for over twenty years.
（）2. He has lived in Shanghai for ten years.
（）3. How long have you come here?
（）4. How many years have you studied English?
（）5. Has she bought the dictionary for about a year? （）6. Has she used this dictionary for about a year? （）7. I have lost my watch for a week.
（）8. How long may I keep your watch?
（）9. I've got to know John for three years.
（）10. I've known John for three years.
（）11. Has your brother become a doctor for five years? （）12. Has your sister worked as a nurse for two years? 答案:1.X2. V3. X4. V5. X6. V7. X8. V9. X

现在完成时的构成英语语法大全
现在完成时的构成 一）肯定式 主语＋助动词have ／has ＋过去分词＋其它 说明：这里的have ／has是助动词，没有什么具体意义。当主语是第三人称单数时助动词 用has，其余人称一律用have。has，have的缩略式分别为's或've。规则动词过去分词的构 成与过去式的构成方式一样，不规则动词可参看不规则动词表。实例： 1）I've just copied all the new words ．我刚抄写了所有的生词。(表示不要再抄了) 2）She has lost her books ．她丢失了她的书。（表示到目前为止还没有找到） (如果用过去时：She lost her books . 则强调书是过去丢的这一动作，而不知现在有没有找到) 3）We've just cleaned the classroom ．我们刚好打扫了教室。（表明现在教室是干净的） 二）否定式 主语＋助动词have ／has＋not＋过去分词＋其它 说明：现在完成时构成否定句时，只需在助动词have ／has后面加not就行。have not，has not的缩略式分别为haven't ，hasn't。另外，肯定句中有some，already时，改为否定时要分 别改成any，yet。实例： 1）I haven't finished my homework yet．我还没有完成我的作业。 2）She hasn't travelled on a train ．她没有坐火车旅行过。 3）We have never spoken to a foreigner．我们从来没有和外国人说过话。 注：有时not可以用never代替，表示“从来没有”的意思。又如： 4）I have never seen him before．以前我从来没有见过他。 三）一般疑问式 助动词Have ／Has ＋主语＋过去分词＋其它？ 说明：把陈述句中的have或has放到句首，句末打问号，同时把句中的some ，already改为any ，ye t就构成了一般疑问句。肯定回答用“Yes ，主语＋have／has．否定回答用“No，主语＋haven't／hasn't．”有时也可以用“No，not yet．／No ，never．／No，not even once．”等。实例：

英语语法完成时篇
完成时篇（一）——现在完成时 [提问] 请问在句子“Working in London has been the best decision I have made so far. （Experiencing English Integrated Book1 Page71）”中，为什么时间状语是完成时的情况下，主句仍然可以使用现在完成时呢？ 答：完成时态通常表示已完成或已经开始从事的动作，它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。根据定义我们可以了解到，除了表示到现在为止动作已经完成或已经开始以外，还有多种情况可以用现在完成时来表达。 一、动作从过去某个时间开始发生，延续到现在，并且说话前已经完成。 例如：The mission has been carried out well.任务已经很好地完成了。 Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。 二、某个动作或状态发生在过去，持续并影响现在，有可能会继续保持下去。 例如：My brother has been abroad for several years.我哥哥已经出国好几年了。 It has rained all morning.雨下了一个早晨。 Up to now, parents have accepted the pop music youths prefer to.现在，家长们 已经接受了年轻人喜欢的流行音乐。 I have known him since the summer in 2001.自2001年的那个夏天，我就认识他了。 三、动作发生在现在之前的某个时间，可能是多次动作的集合，也表示习惯性的动作或 状态。 例如：Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。 Which countries have you traveled recently?最近你都去过那些国家？ How many papers have you read today? 你今天看了几篇论文？ 四、动作过去曾发生过一次或多次，也可能是一种经历。 例如：Students are very pride that the president has once visited their school. 学生们为总统曾访问过他们学校而骄傲。 Accidents like this have happened more than 20 times these years.这几年此类事故发生不下20起。 在现在完成时态的句子中，常伴随的时间状语有：already，yet，ever，never，just，before，lately，recently，till/until，always，now，since，today; in past years，all morning，all one’s life，up to now，these days，this week/month/year，for a long time。 现在完成时中有几点语法点要注意的： 1）for引出的时间状语只能修饰表示延续性动作的动词。不能用来修饰表示瞬间、短 暂动作或位置转移的动词。如John has come to China for three years，此句错误，come这个动作是短暂性动词，不可能持续发生，因此可改为John has been in China for three years，约翰已经爱中国生活了3年。短暂性动词有appear, begin，borrow，buy，come，close，die，fall，find，finish，join，kill，leave，lend，lose，see，start，stop。 2）在表示时间或条件的状语从句可以用现在完成时表示将来完成的动作。 例如：He will not quit my job until his parents have permitted.父母允许后他才会辞职。 I will arrive at 6 o’clock if the car h as been prepared then.如果到时车准备好了，我能在6 点到达。 3）It is the first/second time that…这个结构中，that从句要用现在完成时。 例如：It is the first time that I have heard of his deeds.这是我第一次听说他的事迹。

初中英语语法过去完成时
【初中语法系列】过去完成时，过去的过去！对于理解过去完成时来说，其要义只有一点，那就“过去的过去”。 一.过去完成时的概念与结构 概念： 表示在过去某一时间或动作之前已经发生或完成了的动作，即“过去的过去（past-in-the-past ）”。 构成： “助动词had +过去分词”，其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel.在到达旅馆之前，他们已经吃过了早饭。 二.过去完成时的用法 1.表示一个动作或状态在过去某一时间或动作之前已经完成或结束，即发生在“过去的过去”。例如： When I woke up, it had stopped raing. 我醒来时，雨已经停了。（雨停发生在醒来之前，即“过去的过去”） 2.表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去时间，而且动作尚未结束，仍然有继续下去的可能。例如： By the end of last year, he had worked in the factory for twenty years.到去年年底为止，他已经在这个工厂工作了20年。（到去年年底为止已工作了20年，还有继续进行下去的可能） 三.过去完成时的判断依据 1.由时间状语来判定
一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有： （1）by +过去的时间点，例如： I had finished reading the novel by nine o'clock last night. 到昨天晚上九点钟为止，我已经读完了这本小说。 （2）by the end of +过去的时间点，例如： We had learned over two thousand English words by the end of last term.到上学期末为止，我们已经学了两千多单词。 （3）before +过去的时间点，例如： They had planted six hundred trees before last Wednesday. 在xx之前，他们已经植了六百棵树。 2.由“过去的过去”来判定 过去完成时表示“过去的过去”，是指在过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在： （1）宾语从句中 当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。例如： She said that she had seen the film before. 她说她之前看过这部电影。 （2）状语从句中 在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。例如：
