I have been a teacher for nearly 20 years. How long has he lived here?
2 四、延续性动词的现在完成时可和包括“现在”在内的（到说话时仍未结束）表示一段时间的
状语连用。如this morning，today，this week，these days
He has been to Beijing three times this year. He has written two letters this morning.
（说话时间在上午）He wrote two letters this morning.（说话时间在下午或晚上）
、英语中还有一些动词的意义决定它们所表示的动作不能延续,只是一瞬间
就结束的动作,这类动词叫做“非延续性动词”，常见的有：come，go，arrive，reach，see，hear，close，open，leave，begin，start，lose，buy，fall，join，die，get up，become，borrow，lend，find，finish，receive等。这些动词可用于现在完成时，说明某个动作的结
果还存在，但不能和表示一段时间的状语（how long，for，since）连用。He has come back.（√）He has come back for two hours.（×）
※但在否定句中，非延续性动词也可用表示一段时间的状语来修饰，如
I haven’t heard from my father for a long time. We haven’t seen him since 1999.
六、当终止性动词（非延续性动词）与表示一段时间的状语（how long，since，for，all one’s life）相矛盾时,改正错句的方法有如下几种:
（1）用副词ago把现在完成时的句子改为一般过去时.
He has come back for two weeks.（错）改为:He came back two weeks ago.（正）
I have lost my bike for ten days. （错）改为:I lost my bike ten days ago. （正）
（2）用“It is / has been＋时间＋since＋一般过去时态”句型来改写。
He has joined the League for 3 years. （错）It is 3 years since he joined the League.
I have bought the book for 5 days. （错）It is 5 days since I bought the book. （正）
He has died for 20 years. （错）It is 20 years since he died. （正）
（3）用“时间＋has passed＋since＋一般过去时态”句型来改写。
He has left home for 20 years. 改为:Twenty years has passed since he left home.
He has lost his pen for 2 days. 改为:Two days has passed since he lost his pen.
（4）用系表结构来改写.
He has died for 20 years. 改为: He has been dead for 20 years.
The factory has opened since 1999. 改为:The factory has been open since 1999.
How long has he left? 改为:How long has he been away?
（5）用相应的延续性动词替代非延续性动词。
He has bought the book for two weeks. 改为:He has had the book for two weeks.
常见的相应转换形式如下:
borrow / lend→keep,buy→have,finish / end→be over,
arrive /come / go / move / reach /get to→be in /at / be here /be there,
begin / start→be on , open→be open , close→be closed, die→be dead ,
leave→be away（from）, go to school→be in school / be a student,
get up→be up, fall asleep→be asleep , fall ill→be ill, get to know→know,
lose→be lost, become→be,return / come back / get back→be back,
3 join→be in / be a…member, join the army→be in the army /be a soldier,
receive / get a letter→have a letter , catch / get a cold→have a cold,
begin to study→study,
他参军已有三年.He has joined the army for three years.（错）改为:
He has been in the army for three years / since three years ago.
He has been a soldier for three years / since three years ago.
He joined the army three years ago.
It is three years since he joined the army.
Three years has passed since he joined the army.
（1）He came to our village two years ago.=He our village since two years ago.
（2）He left home three days ago= He home for 3 days.
（3）I bought the watch 2 weeks ago= I the watch since 2 weeks ago.
（4）It is 5 days since I borrowed the book= I the book for 5 days.
（5）The film has begun= The film for half an hour.
（6）I got to know him 10 years ago= I him for 10 years.
（7）There is a factory= There a factory for 20 years.
（8）Our school opened in 1960=Our school since 1960.
七、现在完成时中应注意的几个问题
1. have been to 和have gone to的区别
have been to 强调“去过”，现已不在那里，如：
He has been to the USA three times.
他到美国去过三次。（过去“到美国”，现在已“不在美国”）
have gone to主要强调的是“去了”，现在人不在说话的现场，如：
--Where's your mother? --你妈妈在哪？
--She has gone to the hospital. --她去医院了。
2. have been to 和have been in的区别
have been to强调人“已回到原地”，后面可接表示“次数”的状语。
eg. ① She has been to Shanghai only once.
②--How many times has he been there? --He's been there many times.
4 have been in表示某人“已在某地停留一段时间，现仍在那里”，其后常带表示一段时间的状语。
eg. ①They have been at the bus stop for half an hour.他们在车站呆了半小时。（现在
仍然在车站）
②We have been in Xi'an for two weeks.
我们在西安呆了两个多星期。（现仍在西安）
③How long have they been in China?
他们在中国呆了多长时间了？（仍在中国）
八、如何通过与一般过去时做比较,进一步掌握现在完成时?
一般过去时和现在完成时的动作都发生在过去,但意义却不同.
（1）一般过去时只表示过去的动作或状态,和现在不发生关系。
现在完成时表示过去发生的某一动作对现在造成的影响,强调的是现在。
如:I learned ten English songs（说明过去学过,现在是否记得,不是本句的内容）
I have learnt ten English songs.（learn发生在过去,但强调我现在懂英语歌曲）
I cleaned the blackboard half an hour ago.（只说明“擦”和其发生的时间）
I have cleaned the blackboard.（说明现在黑板是干净的）
The teacher has written some new words on the blackboard（黑板上现在有单词）
The teacher wrote some new words on the blackboard（黑板上现在没有单词）
（2）一般过去时可以和表示过去的时间状语连用,如:yesterday, last year, three days ago, just now, 等。现在完成时不能和表示过去的时间状语连用,其时间状语可以是since…,for… , just, ever, never, before, already, yet , so far, all one’s life等
八、规则动词的过去分词和它的过去式相同,即在原形后加－ed（－d）。已学近80个不规则动
词的过去分词约有半数也和它的过去式相同,分类如下,利于记忆:
1) 原形中的元音字母有变化:
get-got-got, sit –sat-sat win-won-won spit- spat- spat shine –shone- shone
find- found- found hold-held-held meet- met-met stand- stood-stood

5 bring-brought-brought think-thought-thought wear-wore-worn
5) 与原形相同:
hit-hit-hit hurt-hurt-hurt let-let-let put-put-put read-read-read
set-set-set shut-shut shut cost-cost-cost cut-cut-cut
还有些不规则动词的过去分词与过去式不相同,为便于记忆,也分类如下:
1)原形中的元音字母有变化:
ring-rang-rung sing-sang-sung drink-drank-drunk swim-swam-swum
begin-began-begun sink-sank-sunk
2) 在原形上加－en:
eat-ate-eaten fall-fell-fallen ride-rode-ridden write-wrote- written
be-was/were-been rise-rose-risen forget-forgot-forgotten
3)在原形上加－n:
see-saw-seen give-gave-given drive-drove-driven take-took-taken

4)在过去式上加－n:
steal-stole-stolen break-broken–broken choose-chose-chosen speak-spoke-spoken

个别动词有两个过去式和过去分词,一个为规则变化,另一个为不规则变化:
learn-learned-learned shined-shined smell – smelled-smelled
learnt-learnt shine shone-shone smelt-smelt
wake -waked-waked spelled-spelled
woke-woken spell -spelt –spelt

目录 1现在完成时的构成 (2) 2现在完成时的用法 (5) 3 使用现在完成时需注意事项 (7) 4过去完成时与现在完成时的比较 (12) 练习题 (13) 答案 (16)
现在完成时对于我们来讲是所有时态中最难掌握的一种。因为它并不是表示发生于某一时间的事情，而是既涉及过去，又联系现在的一种时态。请参见下列三个例句： 例：1.I live in Beijing. 我住在北京。 2.I lived in Beijing. 我住过北京。（我在北京住过。） 3.I have lived in Beijing. 我一直住在北京。 例1.的live是一般现在式，表示“我现在住在北京”这一事实。 例2.的lived是过去式。这句只是表示在过去的某一时期我在北京住过，至于现在住不住在北京则不清楚。 例3.的have lived是现在完成时，表示我在过去的某一时间开始住在北京，现在也住在北京。表示从过去到现在的一种继续状态。 1现在完成时的构成 现在完成时的形式是“have （has）+过去分词”，表示继续、完了、结果和经验等四种意思。 现在完成时的否定句是在have（has）的后面加上not，疑问句是将have（has）置于主语之前。 1现在完成时的肯定句 句型：
We have lived in Beijing. 我们一直住在北京。 He has lived in Beijing. 他一直住在北京。 过去分词的三种用法 过去分词有下列三种用法（过去分词的构成详见第六章）：1.构成现在（过去）完成时 have（has）+过去分词～ I have written the letter. 我写完这封信了。 2.被动语态：参见第十三章 be + 过去分词～ He was looked after.他受到照顾。 3.用于形容词 This is a broken chair. 这是一张坏的椅子。 2现在完成时的否定句 句型：主语+have（has）+not +过去分词～. I have not seen the movie yet.
英语现在完成时语法详细讲解与配套习题 一、现在完成时用来表示之前已发生或完成的动作或状态，但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词。规则变化的过去分词与过去式的变化一样，在动词词尾加ed; 不规则变化的过去分词见不规则动词表，需要同学记忆。 现以see the film为例将现在完成时的肯定句，否定句和疑问句列表如下： 肯定句：I/You/We/They have seen the film. He/She /It has seen the film. 否定句：I/You/We/They have not/ haven’t seen the film. He/ She/It has not/hasn’t seen the film. 疑问句：Have I/you/they seen the film Yes, you/ we/I/they have. No, you/ we/I/they haven’t. Has he/she/it seen the film Yes, he/ she/ it has. No, he/ s he/ it hasn’t. 二、用法：现在完成时既涉及过去，又联系现在。 标志词词义用法位置 already已经肯定句句中或句末 ever曾经疑问句、肯定句句中 never从未，从来不陈述句，不和not 连用句中 (ever)since自从肯定、疑问、否定句中 for后接一段时间肯定、疑问、否定句中 just刚刚，正好肯定句句中 yet还疑问句、否定句末 recently最近肯定、否定、疑问句句末 once, twice, a few times几次肯定、疑问句末 during/over /in 在过去的一段时间里肯定、疑问、否定句末 the past/last + 一段时 间 It’s the first time I …这是我第一次…肯定句前

初中英语过去完成时态讲解试题 过去完成时态 1）过去完成时态的构成： 肯定式：had + 动词的过去分词 否定式：hadn't + 动词的过去分词 疑问式：Had … + 动词的过去分词 简略回答: Yes, 主 + have/has had. No, 主 + had现在完成时的用法 过去完成时的用法： 1、表示在过去某一时间或动作之前已经发生或完成的动作。他表示的时间是"过去的过去 "常与by last year, by the time of yesterday,等连用。如： She said she had seen the film 4 times. When Mr Li got to the classroom, all the students had begun reading. By the time they arrived, the bus had left. 2、表示从过去某一时间开始一直延续到过去另一时间的动作或状态。常与for (后跟段时间)或since (后跟点时间)等连用.如: She had worked in this school since it opened 25 years ago. 例题解析：举一反三，学的更轻松！ 1. He ______ in Shanghai University for four years before he ______ Beijin g. A. studied, had gone B. had studied, went C. has studied, goes D. had studied, had gone
第六讲现在完成时 1.概念： 1）、表示动作或状态在过去已经开始, 持续到现在, 也许还要持续下去,常和for, since, 连用, 表示持续的动作或状态多为延续性动词. eg: We have lived here since 2000. 自从2000年以来我们一直住在这里. ( 说明一直住在这里, 也许还会住下去. ) She has worked in Nanning for five years. She has been ill for a week. 2）表示过去发生的或已经完成的某一动作对现在造成的影响或结果. eg: I have lost my pen. 我把钢笔弄丢了. ( 过去某时丢的, 现在还没有找到) I have already watched the TV play. 我已经看过这部电视剧了. --- Have you had your lunch yet ? 你吃过午饭了吗? --- Yes, I have just had it. 是的, 我刚吃过. ( 说明现在饱了) 2. 结构: 主语+ have / has + done + … 3. 句型: ⑴肯定句: ①主语+ have / has + done + … eg：She has been to Shanghai. 她去过上海. I have finished doing my homework. 我已经完成我的作业了. ⑵否定句: ①主语+ have / has + not +done + … eg：I haven’t seen this film. 我没有看过这部电影. eg：She hasn’t finished doing his homework. 她还没有完成她的作业. ⑶一般疑问句：① Have / Has + 主语+ done + … eg: Have you seen this film ? Yes, I have. / No, I haven’t . 你看过这部电影吗? 是的, 看过. / 不, 没有. eg：Has she finished do ing his homework ? Yes, she has . / No, she hasn’t. 她完成她的作业了吗? 是的, 完成了. / 不, 没有. ⑷特殊疑问句：①特殊疑问词+ have / has + 主语+ done + … eg: When has you seen this film ? 你什么时候看的这部电影? eg: Who has finished doing his homework ? 谁完成了作业? 4. 时间状语：典型的表时间的词与现在完成时连用，这些词有：
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：

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。
英语语法现在完成时的 基本例句 SANY标准化小组 #QS8QHH-HHGX8Q8-GNHHJ8-HHMHGN#
现在完成时的基本例句： 1．I have worked here since 1970. 自1970 年以来我就在这儿工作。 2．He has been to the Great Wall twice. 他已经去过两次长城了。 3．Mike has just finished his homework. 迈克刚做完他的作业。 现在完成时是描述过去发生的而与现在情况有关的事或状态（例2， 例3），或是从过去某时到现在为止这一段时间中发生的情况（例1），换言之，现在完成时是表现从过去到现在的事情。2 现在完成时的用法现在完成时的形式皆以“ have(has)+过去分词”来表示，有“继续”、“完了”、“结果”、“经验”等用法。 继续 I have studied English for three years. 我已经学习英语三年了。 She has been sick since last month. 她从上个月就生病了。 经验 I have visited Beijing many times. 我访问过北京好多次了。 Have you ever been to Hawaii 你曾经去夏威夷吗 完成 I have just finished my homework. 我刚刚完成我的家庭作业。 Has he finished his work yet 他作好工作了吗 结果 My brother has become a teacher. 我哥哥已经成为一名教师了。 I have lost my watch. 我手表弄丢了。（我现在仍旧没有表）
【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：
现在完成时： 1．构成：have / has + 过去分词 2．功能： （1）表示过去所发生的动作对现在的影响或产生的结果。常与yet, just, before, recently, lately（最近）, ever, never等表时间的副词搭配使用。 ?. He hasn't seen her lately. ?. I haven't finished the book yet. （2）表示一个从过去某个时间开始，延续到现在并可能持续下去的动作，常与表示一段时间的时间状语连用。如：so far（迄今为止）, up till now（直到现在）, since, for a long time （很长时间）, up to present（直到现在）, in the past / in the last few years（在过去的几年里）, these days（目前）…… ?. He has worked here for 15 years. ?. I have studied English since I came here. ?. The foreigner has been away from China for a long time. ?. So far, I haven't received a single letter from my brother. （3）某些非延续性动词（即：动作开始便终止的动词），在现在完成时中不能与表示一段时间状语搭配。 黄金要点：I．常见的非延续动词：die, arrive（到达）, join（加入）, leave（离开）, go, refuse （拒绝）, fail（失败）, finish, buy, marry, divorce（离婚）, awake（醒）, buy, borrow, lend ... II．这类动词并非不能用现在完成时，而是不能接常由for引导的时间状语。 III．但若是用在否定句中，非延续动词的现在完成时可以与表示一段时间的状语连用。?. She has gone away for a month.（误）?. She has been away for a month （正） ?. The man has died for two years.（误）?. The man has been dead for two years.（正）?. How long have you bought the book?（误）?. How long have you got the book.（正）
（Present Perfect）。 第一部分 现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态。学习现在完成时,先从结构和句式开始: 构成:主语 + have/has + 过去分词 + 其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。) 否定式:主语+ haven't/hasn't + 过去分词+ 其他。 疑问式: Have /Has + 主语+ 过去分词+ 其他? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven't/hasn't.(否定) 现在完成时常用的时间状语有： already （”已经”用于肯定句的中间和末尾处） never (“从不”用于中间处) ever （”曾经”用于疑问句和肯定句的中间处） just (“刚刚”用于中间处) yet (“已经”用于疑问句的末尾处/ “还”用于否定句的末尾处) 或不加任何的时间状语，但不能和表示过去的时间状语连用. 第二部分 现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 He has already got her help. 他已得到她的帮助。 He has just seen the film. 他刚刚看过这场电影。 He hasn't come back yet. 他还没有回来。 * 以ever和never为标志 ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 * 以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 He says he has been to the USA three times. 他说他已经去过美国三次了。 * 以so far为标志 so far往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the examso far. 到目前为止她已经通过了。 第三部分 过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。 *“终止”、“延续”要转换
现在完成时 现在完成时 一、结构： have / has +动词过去分词 haven’t / hasn’t + done Have / Has + 主语+ done 二.用法：表示到说话时刻为止已经做或尚未做过的动作。常用already, yet, so far, by now, since two days ago, for a few days 等词语作状语。 注：give, see, come, arrive, leave(离开)，begin, start, finish, join, become, borrow, lend, die, end 等点时间动词可以用于完成时，但在肯定句中不能与表示一段时的since和for 短语连用，因为点时间动词不能延续，而在否定句中可以与表示一段时间的for短语连用，因为否定的点时间动词可以看作是一种可延续的状态。 Mike has come for a year.( 〤) Mike has been here for a year( √) Mike hasn’t come for a year.（√） 过去完成时 表示截止到过去某一时刻或在过去的动作之前（过去的过去）已经做或尚未做的动作。 B y (=up to )last weekend we hadn’t got any information. When he appeared, we had waited for 30 minutes. 现在完成时考点 考点一：考查基本概念 例Both his parents look sad . Maybe they ______what's happened to him .Ａ. knew Ｂ. have known Ｃ. must know Ｄ.will know 考点二：考查时间状语 例1.
