篇1: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)
篇2:英语时态学习:现在完成时时态讲解
现在完成时:
构成:have (has) +过去分词
含义:
1)在完成时用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;
2)也可表示持续到现在的动作或状态。
句型:
1)It is the first / second time.... that…结构中的从句部分,用现在完成时。例如:
It is the first time that I have visited the city. 这是我第一次访问这城市。
This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
注意:It was the third time that the boy had been late.

篇3:英语时态之将来进行时
语法构成
将来进行时是由“shall/will + be+ 现在分词”构成的。
例如:Don't phone mebetween 8:00 and 10:00. We'll be having classes then.(8点到10点之间不要给我打电话,我们那时正在上课。)
主要用法
1、表示在将来某一时间正在进行的动作。如:
He will be reading in the library from 3 to 5 this afternoon. (他今天下午会在图书馆看书。)
2、表示按预定计划将来会发生的事情。如:
The band will be playing at twenty different venues on their UK tour. (这个乐队在英国巡回演出期间将在二十个不同的地点演出。)
3、表示对将来的预测。如:
Take this medicine and you will be feeling better soon. (吃了这些药,你就会感觉好多的。)
4、表示委婉请求。如:
When shall we be meeting again?我们什么时候再见面?
特殊用法
1. 将来进行时表事情的发展:
例如:I'll be seeing Mr.Smith tomorrow.(我明天将见到史密斯先生。)
注意:有时这种时态含有一种附带的意思,语气较为委婉。例如:I'll be finishing it.(我一会儿就完了。)附带的含义可能是“过一会儿你就会拿到它了。”
2. 将来进行时表原因、结果、可能:
表原因――Please cometomorrow afternoon. Tomorrow morning I'll be having meeting.(请你明天下午来吧。明天上午我有一个会。)
表结果――If I fail toappear by 7 o'clock, I will not be coming at all.(如果我七点钟不到,我就不会来了。)
表可能――He will betelling you about it tonight.(他今晚会告诉你这件事。)
3. 将来进行时表委婉:
例如:Will you beneeding anything else?(你还需要什么吗?)
4. 将来进行时与将来一般时连用:将来进行时常可置于将来一般时之后表稍靠后的安排。
例如:My duties will endin July and I will be returning to Arizona in the US.(我的工作七月结束,之后我将回到美国亚利桑那州。)
注意点
1)这种将来进行时也可和其他表将来的时态连用。
例如:I'm going to do myhomework first, and then I'll be watching TV.(我将先做作业,然后再看电视。)
2)在下面的句子中,will是情态动词,意谓“大概”或“一定”,不表将要而表现在,常与now连用。
例如:They’ll be watching television now.(他们现在大概在看电视呢。)
一般将来时与将来进行时的区别
两者的主要区别在于:一般将来时表示将来会发生的事情,但不表示将来正在进行的动作。如:
I will attend your birthday party tomorrow. (我明天会参加你的生日派对。)
She will be working in the garden at this time tomorrow. (明天这个时间,她会在花园里干活。)

篇5:初中英语语法知识点之时态
初中英语语法知识点之时态
初中英语时态知识点:过去进行时的用法详解
(1) 表示在过去某一时间正在进行的动作,此时句中往往有表示过去的时间状语then,at that time,this time,yesterday等。
I was doing my homework when my mother came to home.
(2)叙述在过去的同一时间都在进行的几个动作,通常用While
I was studying at college while my brother was teaching at university..
(3)表示在过去某一段时间内一直持续进行的动作
They were expecting you yesterday, but you didn't turn up.
初中英语时态知识点:一般现在表过去的用法
1.用于某些动词(tell, say, hear, learn, gather等)表示不确定的过去时间:
John tells me you will leave tomorrow. 约翰告诉我你明天离开。
I hear that he got married last month. 我听说他上个月结婚了。
I hear you want a secretary. 我听说你需要一个秘书。
He says the matter is rather urgent. 他说这事相当紧急。
Mary says you told her to come over here. 玛丽说是你让她到这儿来的。
It really gets me when he says those stupid things. 他说那些傻话真让我生气。
2.当要陈述一个客观事实时,有时即使有过去时间状语也可用一般现在时:
The story is set in the summer of 1937. 故事的背景是1937年夏天。
The story begins in the year 1937. 故事开始于1937年。
初中英语时态知识点:运用现在进行时常见的几个错误
1、把动词变成现在分词形式易出错。例:
(1)误:They are swiming (swim) .
正:They are swimming (swim).
(2)误:Jenny is plaiing (play) football.
正:Jenny is playing (play) football.
解析:A、动词变现在分词可有如下口诀:一般-ing;哑e先去e;重闭单辅先双写;-ie结尾y来替。
B、动词现在分词的变化规则要与名词变复数、动词变现单三等规则区分开来。
2、谓语部分的构成不完整:丢掉be动词,或忘记把动词变成现在分词。例:
(1)误:Look! Two children flying (fly) a kite in the park.
正:Look!Two children are flying (fly) a kite in the park.
(2)误:Li Ming isn't read ( not read) a book in bed now.
正:Li Ming isn't reading ( not read) a book in bed now.
解析:现在进行时的谓语部分的构成是“be+现在分词”,二者缺一不可,这一点必须要牢记。
3、对动词或动词词组提问时,丢掉代动词doing。例:
The students are singing in the room.(对划线部分提问)
→误:What are the students in the room?
→正:What are the students doing in the room?
解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”或简写为“What......doing......? ”句式。
4、现在进行时态的谓语部分是并列结构时,容易忽视第二个以及第二个以后的动词用现在分词形式。例:
孩子们在跑还是在跳?
误:Are the children running or jump?
正:Are the children running or jumping?
解析: or连接的是两个并列成分,动词形式须一致。
初中英语时态知识点:现在进行时的应用
(1) 表示目前正在发生或进行的动作。如:
They are planting trees on the mountain. 他们在山上植树。
Mother is preparing supper in the kitchen. 母亲在厨房做晚饭。
(2) 有些非持续性动词的进行时可以表示动作即将进行或发生,或表示动作的重复。如:
He is joining the army. 他要参军了。
They are buying the house. 他们要买那座房子。
(3) 当现在进行时中有always, forever, constantly, continually修饰时,表示说话人的赞赏或厌烦的感情。如:
Why is the baby always crying? 为什么那个老是在哭。
They are always helping us. 他们总是帮助我们。
注意:表示状态、感觉、心理活动的静态动词,一般不使用语进行时态。
初中英语时态知识点:过去完成时由过去的过去来判定
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.
( 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。如:
When I got to the station, the train had already left.
After he had finished his homework, he went to bed.
注意: before, after 引导的时间状语从句中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:
Where did you study before you came here?
After he closed the door, he left the classroom.
( 3 )表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示“原本…,未能…”
We had hoped that you would come, but you didn't.
初中英语时态知识点:过去完成时与一般过去时的区别
虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:
1. 时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。试比较:
They had arrived at the station by ten yesterday.
They arrived at the station at ten yesterday.
2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。如:
She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.
3. 当两个或两个以上接连发生的动作用 and 或 but 连接时,按时间顺序,只需用一般过去时来代替过去完成时;另外,在 before , after , as soon as 引导的从句中,由于这些连词本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时。如:
He entered the room, turned on the light and read an evening paper.
I (had) called her before I left the office.
