教学过程

一、课堂导入

时态在中考中,单选会考1至2题,完形填空里面对副词的考查也是比较多的,所以也是需要好好掌握的语法点。

二、复习预习

复习上一单元的知识点之后,以达到复习的效果。然后给学生一些相关的单选或其他类型题目,再老师没有讲解的情况下,让学生独立思考,给出答案与解释,促进学生发现问题,同时老师也能发现学生的盲点,并能有针对性地进行后面的讲课。

三、知识讲解

知识点1:现在完成时与过去完成时:

1【考查点】现在完成时:构成:主语+ have/has + 动词的过去分词

用法:

1)过去发生的某一动作对现在造成的影响或结果,句中常有already, just, never, ever, lately, recently, , in the past+一段时间,so far等状语

2)、从过去开始,持续到现在的动作或状态

3)、用在时间、条件从句中,表示从句动作先于主句动作之前完成

4)、“最高级+名词”或“It is the + 序数词+ time”后的定语从句中。

5)、应用现在完成时应注意:

瞬间动词用于完成时表示一个动作的结束,不能和“for…”或“since…”连用,但它们的否定形式

可以连用。如:

We have not heard from him for ten days.我们已经十天没他的消息了。

另外,如果把瞬间动词转变成相应的持续动词,就可和“for…”或“since…”连用。

2【考查点】过去完成时:构成:主语+ had + 动词的过去分词

用法:

1)、表示过去某时间或动作之前已发生或完成的动作。

2)、表示从过去某时间开始,持续到过去另一时间的动作或状态,往往和for, since引导的短语或从句连用。

3)、用于句型:It was the +序数词+ time that…

该句型表示到“was”时已是第几次做某事,即在“was”前已做过某事几次,因此该句在时间上体现“过去的过去”,所以应用过去完成时。

4)、用于句型:It was + 时间段+ since…

该句型表示到自从做某事以来已有多长时间,即在这个(过去)时间段之前已做某事,因此该句型在时间上体现“过去的过去”,应用过去完成时。

They asked me to have a drink with them. I said that it was at least ten years since I had enjoyed a good drink. 5)、过去没有实现的想法、希望和打算,即“本打算”

We had intended to see you, but we weren’t free.

6)当句中出现by the end of+过去的时间或者by the time +过去的时间,那么该句要用过去完成时。

四、例题精析

【例题1】He was unhappy when he sold his guitar. After all, he ______ it for a very long time.

A.has had

B. had had

C. has

D. Had

【答案】B

【解析】考查动词时态。本题基础时态为一般过去时,他演奏吉他很长时间是发生在他卖(sold)之前,故用过去完成时态。

【例题2】—Oh no! We’re too late. The train _______.

—That’s Ok. We’ll catch the next train to London.

A.was leaving

B. had left

C. has left

D. has been leaving

【答案】C

【解析】考查动词时态。根据语境“我们太晚了”及后句“没关系。我们可以赶下一趟火车去伦敦”,可知火车已经离开,对现在造成影响,故使用现在完成时态。

【例题3】When I first met Bryan I didn’t like him, but I ___ my mind.

A. have changed

B. change

C. had changed

D. would change

【答案】A

【解析】考查动词时态。根据句意:我第一次见到Bryan时我不喜欢他,但是现在我已经改变我的想法了。

【例题4】During the last three decades, the number of people participating in physical fitness programs

______ sharply.

A.was increasing

B. has increased

C. had increased

D. will be increasing

【答案】B

【解析】考查动词时态。根据时态标志词during the last three decades,可知使用现在完成时态,选B。

课程小结

该知识点是中考里面的一个的热点,不算很难的知识点,变化规则比较多,需要学生们通过一定量的练习达到巩固熟练的程度。

现在完成时和过去完成时

现在完成时和过去完成时这两个时态的相似之处是动作都发生在过去,差别是两个时态所对应的时间参照点不一样。 现在完成时的动作发生在过去,但是时间参照点是现在。 过去完成时的动作发生在过去,但是时间参照点是过去的某一时间。 请看下面两个例句 I have lived in Thailand for five years. (我在泰国已经住了五年了) live(居住)是上面例句的谓语,那么这个动作显然是发生在过去(五年前),但是一直持续到现在,我们的时间参照点是“现在、当下”。 我们再看下面一个例句: I had lived in Thailand for five years before I went to China. (在我来中国之前,我已经在泰国住了五年了) live这个动作发生在过去,是前面句子的谓语,但是整句话的时间参照点变成了before I went to China,这个动作也是过去的一个时间点,所以我们要把go变成went。 所以从上面两个例句中大家可以看出,其实这两个时态的不同之处就在于时间参照点的不同。 总结一下,现在完成时用来表示过去发生的动作对现在造成的影响,通常我们可以用现在完成时态表达三类情况: 第一、经验 I have seen that movie before. (我之前看过那部电影) 凡是我们谈论之前的经验,看过、听过、吃过、去过、读过等等的经验都可以用现在完成是来表达,那么上面例句的意思是我不仅看过那部电影,而且我对电影的情节还有印象。

第二、持续 I have known John since we were kids. (当我们还是小孩的时候我就认识John了) Know(认识)这个动作发生在过去,而参照点是现在,说明我们现在还是朋友,而且友谊还可能继续持续下去。 第三、改变 I have bought a new car. (我买了一辆新车) buy这个动作发生在过去,但是时间参照点是现在,其实言下之意是我不仅买了一辆新车,而且这辆新车我现就在我家,我随时都能用。之前没有车,现在有车了,这就是改变。 那么过去完成是则是谈论过去的两个动作谁先谁后的问题,请看下例: The plane left at 5 pm. (飞机下午五点起飞的) -We arrived at the airport at 6 pm. (我们六点到的机场) 上面两个句子都是一般过去时,表示两件完整的发生在过去的事情,这个时候我们可以用过去完成时态把这两个句子串起来,就变成了下面的句子: The plane had left when we arrived at the airport. (当我们到达机场的时候飞机已经起飞了) 上句中有两个动词,一个是left(离开),另一个是arrived(到达),后面“到达”这个时间就是我们这句话的时间参照点,发生在过去,那么“离开”要先于到达,所以我们在先发生的动作前面加上一个had构成过去完成时,表示这个动作发生在前。 所以现在完成时谈论的是:“过去的动作对现在的影响,时间参

1)过去发生的某一动作对现在造成的影响或结果,句中常有 already,just,never,ever,lately,recently,,inthepast+一段时间,sofar等状语 2)、从过去开始,持续到现在的动作或状态 3)、用在时间、条件从句中,表示从句动作先于主句动作之前完成 4)、“最高级+名词”或“Itisthe+序数词+time”后的定语从句中。 5)、应用现在完成时应注意: 瞬间动词用于完成时表示一个动作的结束,不能和“for…”或“since…”连用,但它们的否定形式可以连用。如:Wehavenotheardfromhimfortendays.我们已经十天没他的消息了。 另外,如果把瞬间动词转变成相应的持续动词,就可和“for…”或“since…”连用。 知识点2:现在完成进行时:构成:主语+have/has+been+动词的现在分词 用法: 表示动作从过去一个时间开始,一直延续到现在,强调在此阶段时间里,动作一直在进行。 ⑴、过去开始而且现在仍在进行的动作 ⑵、过去开始,现在刚刚停止的动作 ⑶、现在看到其直接结果的动作 知识点3:过去完成时:构成:主语+had+动词的过去分词 用法: 1)、表示过去某时间或动作之前已发生或完成的动作。 2)、表示从过去某时间开始,持续到过去另一时间的动作或状态,往往和for,since 引导的短语或从句连用。

一般过去时-现在完成时和过去完成时

一般过去时,现在完成时和过去完成时 一般过去时态表示过去某个时间发生的动作或存在的状态,常和表示过去的时间状语连用,也表示过去经常或反复发生的动作,常和表示频度的时间状语连用,试看下列例句: 1. I was in the classroom yesterday morning 2. My father was at work last week. 3. I visited the Palace Museum three weeks ago. 4. He always went to work by bus last year. 5. I wrote home once a week at college. 1. yesterday或以其构成的短语:yesterday morning(afternoon, evening)等; 2. 由"last+一时间名词"构成的短语:last night, last year (winter, month, week)等; 3. 由"时间段+ago"构成的短语:a moment ago, a short time ago, an hour ago等; 4. 其它:just now或者由句子本身的时态所反映出来的。 现在完成时表示:(1)过去发生或已经完成的动作对现在造成的影响或结果, 常与already,just,yet,before,ever,never 等副词连用;(2)发生在过去某一时刻的,持续到现在的动作(用行为动词表示)或状态(be动词表示),常与for(+时间段),since(+时间点或过去时的句子)连用。试看下列例句: 1.My father has brought many books for me , so I can do some reading now. 2.I have already finished my homework, so I can give it to my teacher now. 3.Kevin hasn't seen the film yet, so he has nothing to say about the film. 4.This is the best film I have ever seen. 5.Mary has been ill for three days. 6.I have lived here since 1998. 现在完成时不能和表示过去的时间状语连用,如yesterday, last year, two days ago, just now 等等,但可以和already, yet, sometimes, always, before, recently,ever, never等连用。

现在完成时和过去完成时的区别

I have cleaned the classroom .(强调扫地所产生的结果:地干净了!) We have lived here for ten years.(“住”从过去持续到现在的动作用现在完成时) We have lived here since we came here.(“住”是从过去持续到现在的动作用现在完成时) Mr Green had lived in New York for ten years before he came to China.("来”中国已过去,而先前“住”在纽约更过去!)(另外注意:“住”在纽约可没有持续到现在!) We had learned 1000 words by the end of last term. (“上期期末”已过去,而是在其前“学”的就更过去了!) 一、从结构上区别 现在完成时: 主语 + have / has(not) + 过去分词 过去完成时: 主语 + had (not) + 过去分词 (二)从时间状语区别 现在完成时: 常用的时间状语包括“now, today, tonight, this week, this year, already, yet, just, recently…etc”。 过去完成时: 常用的时间状语包括“by, at, before等构成的短语”。 注意:当表示一段时间,现在完成时和过去完成时都可以用for 或since引导的状语。 例如: The meeting had begun when we got there. 我们到那儿时,会议已经开始了。 We had learned about 500English words when we were 6 years old. 我们六岁时就已经学了500个英语单词。

现在完成时态和过去完成时态1

现在完成时态和过去完成时态 一.现在完成时态: 1.定义:表示从过去某一时间开始一直持续到现在的动作或状态。 2.构成:助动词Have (has) +动词的过去分词 注:has 用于第三人称单数,have 用于其他所有人称。 如:He has come here for ten years. (他来这里已经有十年了。) He hasn’t come here for ten years. (他来这里没有十年。) Has he come here for ten years? (他来这里已经有十年了吗?) Yes, he has. (是的, 有十年了。)No, he hasn’t.(不,没有十年。) 3.可与现在完成时态连用的词语 1)可与宾语从句连用,后接的宾语从句可以用任何时态。 如:Have you known how big the box is? 你知道这个盒子有多大吗? 2)与时间状语连用。它可以和包括现在时间在内的时间状语连用,如:today (今天), this week (这个星期), now(现在), this year(今年), often (经常),sometimes(有时候)。 如:Have you seen him today? 你今天见过他吗? He has lived here for five years now. 到现在他已经在这里住了五年了。 3)与since(自…以来), for(经历), before (在…前), after(在…后)等引导的短语或从句连用。 Since 后面跟具体的时间,或者后面跟一个从句。 如:He has lived here since 1970.(自从1970年以来他就住在这里。) He has lived here since he came here.(自从他来这里以来就住在这里。) For后面接表示一段时间的短语。 They have been here for two years.(他们在这里两年了)。 After I have had supper, I often do homework.

(完整)初中现在完成时和过去完成时讲解及综合练习

一、过去完成时的概念与结构特点 概念:过去完成时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 )”。 ----|-------------------------- |-------------------------------|----------------------------> 那时以前那时现在 构成:过去完成时由“助动词had + 过去分词”构成,其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 :00 this morning. 二、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。如: I had finished reading the novel by nine o'clock last night. ( 2 )by the end of + 过去的时间点。如: We had learned over two thousand English words by the end of last term. (3 )before + 过去的时间点。如: They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。 过去完成时表示“过去的过去”,是指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。在told, said, knew, heard, thought等动词后的宾语从句。如: She said that she had seen the film before.

最新一般过去时、现在完成时、过去完成时复习

一般过去时、现在完成时、过去完成时复习 一.比较过去时与现在完成时 1)过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。 2)过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。 一般过去时的时间状语: yesterday, last week,…ago, in1980, in October, just now, 具体的时间状语 共同的时间状语: this morning, tonight,this April, now, once,before, already, recently,lately 现在完成时的时间状语 for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 不确定的时间状语 3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know. 过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married 等。 举例: I saw this film yesterday. (强调看的动作发生过了。) I have seen this film. (强调对现在的影响,电影的内容已经知道了。) Why did you get up so early? (强调起床的动作已发生过了。) Who hasn't handed in his paper? (强调有卷子,可能为不公平竞争。) She has returned from Paris. 她已从巴黎回来了。 She returned yesterday. 她是昨天回来了。 He has been in the League for three years. (在团内的状态可延续) He has been a League member for three years. (是团员的状态可持续) He joined the League three years ago. ( 三年前入团,joined为短暂行为。) I have finished my homework now.
