第一篇:一般過去時的否定和疑問式
一般過去時的否定和疑問式
1、Be動詞的否定式,直接在 was / were 后加not。例如: He was not / wasn’t a student then.那時他不是學生。They were not /weren’t at home yesterday.他們昨天不在家。
2、行為動詞的否定要借助助動詞do的過去式did,加 not 來構成否定式。例如:
They did not /didn’t come yesterday.他們昨天沒有來。He did not /didn’t go to work yesterday.他昨天沒有去上班。
3、動詞have 的否定。當have 表示“有”或“擁有”時,其過去式是had,否定用had not /hadn’t。
當表示的不是“有”或“擁有”時,否定用did not /didn’t.例如: He had not /hadn’t any money with him.他身上沒有帶錢。He did not /didn’t have supper that night.他那天晚上沒吃晚飯。
4、一般疑問句:把did放在句首。
Did you go to work yesterday? Yes, I did.No, I did not /didn’t.Did they give you any help? Yes, they did.No, they did not / didn’t.在表示過去的句子中往往都有一個表示過去的時間詞或短語來做狀 語,說明動作發(fā)生的時間,一般都放在句尾。這些時間詞常用的有:yesterday, last night, last week, last month, five minutes ago 等。
5、特殊疑問句:特殊疑問詞 + 一般疑問句。What did you do yesterday? 昨天你干什么?
Where did you go yesterday afternoon? 你昨天下午去哪里了?When did you meet him? 你什么時候遇見他的? Who did you see there? 你在那兒看見誰了?

第三篇:一般過去時和現(xiàn)在完成時
1.一般過去時表示過去某個時間發(fā)生的事、存在的狀態(tài)或經常發(fā)生的動作。說話的側重點只在于陳述一件過去的事情,不強調對“現(xiàn)在”產生的影響。如:He visited Guilin in 1998.他1998年參觀過桂林。(只說明去桂林的時間,現(xiàn)在干什么和你和我和大家無關,只是說明他以前去過.)
2.現(xiàn)在完成時表示動作發(fā)生在過去,對現(xiàn)在造成了影響或產生了結果。不與確定的過去時間狀語連用。如:Jill has bought a new computer.吉爾買了一臺新電腦。(是過去買的,但著重點是現(xiàn)在,現(xiàn)在有了一臺新電腦了.已經買了,不用再買了.)
3.兩種時態(tài)的區(qū)分
(1)一般過去時的謂語動詞用過去式,而現(xiàn)在完成時的謂語基本構成是“助動詞have /has +過去分詞”。
(2)一般過去時通常與表示過去的時間狀語連用。如:yesterday, last week, two years ago, just now, in 2002等;而現(xiàn)在完成時則常與just, already, ever, never等副詞和these days, this week, since..., for...等表示一段時間的狀語連用。
看看以下的幾組句子,有什么區(qū)別?
① Have you seen the film?(A)
Did you see the film?(B)
[說明] 你看過這部電影嗎?(A)句強調的是被問者對劇情是否了解;(B)句強調的是看這部電影的動作是否發(fā)生過,并不強調是否知道其內容。
② How has he done it?(A)
How did he do it?(B)
[說明]他是怎么做的這件事?(A)句強調的是他做這件事的方式對現(xiàn)在產生了某種影響;(B)句單純的詢問做這件事的方式。
③ He has lived in Beijing for 8 years.(A)
He lived in Beijing for 8 years.(B)
[說明]他在北京住了8年。(A)句講的是到目前為止他在北京住了8年,可能還會繼續(xù)在北京住下去。(B)句講的是他在北京住過8年,現(xiàn)在不在北京了。
如果你只是要陳述你做了什么,陳述的東西和目前狀況沒有太大影響,就用一般過去時。比如說 i washed the plate.我洗盤子了,topic基本到此打住,基本沒有下文。還有一種最簡單的過去時情況就是,如果別人用過去時問你,你自然要用過去時回答。
但是你要用現(xiàn)在完成時,效果就不一樣了。
i have washed the plate.我已經洗好盤子了。強調做過,完成了。還有意思是,既然我已經洗好盤子了,我就該干什么什么了,或者你就應該履行什么承諾之類的,你可以好好感覺一下,這個語感是和漢語通用的,我感覺。
過去完成時就是強調,在過去的那個點,我已經完成了
現(xiàn)在完成時用法解析
1.構成現(xiàn)在完成時是由助動詞 have(has)+動詞的過去分詞構成。助動詞說明該謂語是屬于現(xiàn)在時范圍。它和主語的人稱、數(shù)要保持一致。過去分詞是主要的謂語動詞,說明句子的意義。
2.用法
(1)表示動作發(fā)生在過去某個不確定的時間,但對現(xiàn)在留下了某種影響和結果。常被just、already、yet 等副詞修飾。如:
-Have you had lunch yet?-Yes,I have.I've just had it.你(已經)吃午飯了嗎? 我剛剛吃過。(現(xiàn)在我不餓了)
(2)表示從過去某一時刻開始一直持續(xù)到現(xiàn)在的動作或狀態(tài)。這個動作可能剛停止,可能仍然在進行。常帶有for和since等表示一段時間的狀語。如:He has taught here since 1981他自1981年就在這兒教書。(可能還要繼續(xù)教)
I have't seen her for four years.我有四年沒見到她了。
(3)表示說話前發(fā)生過一次或多次的動作,現(xiàn)在成為一種經驗,一般譯為漢語“過”,常帶有twice,ever,never,three times等時間狀語。
如: I have been to Beijing twice.我去過北京二次。
3.現(xiàn)在完成時的時間狀語
(1)現(xiàn)在完成時屬于現(xiàn)在時范圍,故不能和過去的時間狀語連用。如:yesterday,last
Sunday,in1990,three years ago等。但是,在強調動作產生的后果和影響時,可以和一些表示不確定的時間狀語連用。
a.用副詞already和yet。already一般用于肯定句中,yet一般用于否定句和 疑問句中。如:We have already finished our homework.我們已完成作業(yè)了。
They haven't finished their homework yet.他們還沒有完成作業(yè)。
b.用ever 和never。多用于否定或疑問句中,表示“曾經”或“從未“等。如:-Have you ever been to the Great Wall?你曾經去過長城嗎?
-I have never been to the Great Wall.我從未去過長城。
c.用表示到說話為止的過去時間狀語,如just,before,up to now,the past few years等。例如:I have seen her before,but I can not remember where.我以前見過她,但記不起在哪里見過。
He has been there three times the last few days.近幾年他去過那里三次了。
d.用包括“現(xiàn)在”在內的時間狀語,如:now,today,this morning(month,year,term)等。例如:-Have you met him today?-No,I haven't.今天你見過他嗎?我 沒有。
How many times have you been there this year?
今年你去過那里多少次?
(2)現(xiàn)在完成時可以和帶有since或for等表示“一段時間”的狀語連用,表示動作或狀態(tài)從某一時刻開始,一直持續(xù)到現(xiàn)在。如:I haven't seen him for two years.但是,像come,arrive,buy等終止性動詞不能與表示“一段時間”的狀語連用。要用,必須改為“be(在)”等延續(xù)性動詞來表述?,F(xiàn)歸納總結一下由非延續(xù)性動詞到延續(xù)性動詞的轉換:
arrive→be herebegin(start)→be on
die→be dead
fall ill(sick,asleep)→be ill(sick,asleep)
get up→be upgo out→be out
finish →be overput on→wear 或be on
open→be openjoin→be in或 be a member of…
close→be closedgo to school→be a student
borrow→keepbuy→have
catch(a cold)→ have(a cold)get to know →know
begin to study→studycome to work→work等
如:He has been a soldier for three years.他參軍三年了。
His father has been dead for two years.他父親去世二年了。
The film has been on for ten minutes.電影已開始十分鐘了。
We have studied English for three years.我們(開始)學英語已三年了。
4.現(xiàn)在完成時和一般過去時的區(qū)別
現(xiàn)在完成時和一般過去時都表示在過去完成的動作。但現(xiàn)在完成時強調的是這一動作與現(xiàn)在的關系。如對現(xiàn)在產生的結果或影響等,而一般過去時只表示動作在過去某一時刻發(fā)生,不表示和現(xiàn)在的關系。試比較:
I have lost my new book.我把新書丟了。(現(xiàn)在還未找到)
I lost my new book yesterday.我昨天把新書丟了。(昨天丟的,現(xiàn)在找到與否沒說明)
5.幾點注意事項
(1)have been(to)與have gone(to)的區(qū)別:have been(to)表示“去過某地(現(xiàn)在已經回來了)”,可用于各人稱;have gone(to)表示“去某地了(說話時某人不在當?shù)兀?,常用于第三人稱,前者可與once ,never,several times等連用,后者則不能。如:They have been to Beijing twice.他們去過北京兩次。
He has gone to Beijing.他去北京了。
(2)如單純表示一段時間,或強調一段時間,雖有since一詞,也不必用完成時。如:It is two years since his father died.=His father has been dead for twoyears.他父親去世已有三年了。
(3)終止性動詞現(xiàn)在完成時的否定式,已變成一種可以延續(xù)的狀態(tài),因此可以和表示一段時間的狀語連用。
如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這
when, while和as的用法:
(1)三者均可表示“當……的時候”,如果主句謂語動詞表示的是短暫的動作,而從句表示的是一段時間,三者可以通用。例如:
I met an old friend of mine as / when / while I was walking along the street.(當我沿街散步時,碰見了我的一個老朋友。)
(2)as和when引導的時間狀語從句中,謂語動詞可以是終止性動詞,while引導的時間狀語從句中,謂語動詞一般是延續(xù)性動詞。例如:
It was raining hard when we got to the airport.(當我們到達機場時,天正下著大雨。)(不能用while 引導)
(3)as強調主句謂語動詞與從句謂語動詞表示的動作同時發(fā)生;while強調主句謂語動詞表示的動作持續(xù)于while從句所指的整個時間內;when可以指主句謂語動詞和從句謂語動詞所表示的動作同時或先后發(fā)生。例如:
She sang as she went along.(她邊走邊唱。)
Please listen to me carefully while I read.(我朗讀的時候,請仔細聽。)
When he reached home, he had a little rest.(回到家以后,他休息了一會兒。)
also,too
這兩個詞都是副詞,又都表示“也是”的意思,但在修辭意味和使用場合上有所不同。它們的區(qū)別如下:
(一)一般說來,also用于比較正式(formal)的場合,語氣比too莊重; too是慣熟(familiar)的用語,使用范圍較廣。
(二)also在句中的位置要緊靠動詞; too在句中的位置比較靈活,有時插入句中,前后用逗號分開,有時放在句末。
(三)too只能用在肯定句中,不可用于否定句內。在否定句中,只能用either;also則可以用在否定句中。
下面請看例句:
The Hong Kong Chief Executive also heads the university as Chancellor.
香港行政長官也以(大學)校監(jiān)身份領導大學。
Reading books is learning,but application is also learning and the more important form of learning. 讀書是學習,買踐也是學習,而且是更重要的學習。
We have not heard such a thing.,we also have never seen such a scene.
我們沒有聽見過這種事情,我們也從來沒有見過這種場面。
請注意,一般說來,also在句中的位置應緊靠動詞,但有時為了強調其意,也可以將它放在句首或句末。Here,too,the colon must be followed by a dash.
這里也一樣,應當在冒號之后加破折號。
Mary,too,can play the piano.
瑪麗也會彈鋼琴。
Could you speak Japanese?—Yes,and Spanish too.
您會說日語嗎?——會的,還會說西班牙語哩。
Also雖然和too同義,但前者大都用于書面語,后者大都用于口語。例:
The lady washed the children and also gave them dinner.(書面語)
The lady washed the children and gave them dinner too.(口語)
as well as也;和…一樣;不但…而且
作并列連詞相當于not only…but also和no less…than,但not only…but also側重在后項,no less…than 側重在前項。例如:
We must learn to look at problems all-sidedly, seeing the reverse as well as the obverse side or things.A true man should be practical as well as far-sighted.我們必須學會全面地看問題,看到它的反面正面的或事情。
一個真實的人應該是實用性以及具有前瞻性。
在否定句中,as well as 的位置不同,句意往往有很大差別。比較下面的句子:
He, as well as she, will not come.他將不來,她也將不來。
He will not come as well as she.她將來,但他將不來。(否定前者,肯定后者)
Henry, as well as his brother, doesn''t work hard.亨利同他弟弟一樣,工作不努力。
Henry doesn''t work hard as well as him brother.亨利工作不努力,但他弟弟努力。
as well as 連接的應是平等成分,都作主語或都作賓語等。例如:
She was there as well as me.(誤)
She was there as well as I.(正)
else與other的區(qū)別
other 是形容詞性,所以other修飾名詞。other people。
other
主要地是adj, pron
剩余的,其余的,多 余的;其他的;不同的Where's my other glove?
我的那只手套在哪兒?
John and the others are here.約翰和其他人都在這兒。
I haven't brought many cakes.Could you get some others?
我沒有多買糕點,你有多余的嗎?
Think of others as well as yourself.不僅要想到自己,也要想到別人。
else 只修飾兩類詞
修飾 不定代詞 如 someone / someplace/ anything來指代另外一個,而不特別指明哪一個。如: i had nothing else to do
修飾 wh-word。如what /who/where等
如 what else do i need to do我需要做什么其他的?
else多用于特殊疑問詞后。
而other主要修飾名詞,放在名詞前面

表示過去發(fā)生而持續(xù)到現(xiàn)在的動作或狀態(tài)。常與since, for連用。謂語動詞必須是延續(xù)性動詞。HHHHHHHHHHHHjjj Hjkasjfklasjfklasdjl;fj he He has been in Hong Kong for ten years.He has learned English for six years.He has learned English since 1997.強調不久前剛剛完成的動作。常與yet(用于否定和疑問句), just, already連用,謂語動詞是終止性動詞。
He has just gone out.I have already finished my lunch.與一般過去時的區(qū)別。一般過去時表示事情發(fā)生在過去,不強調與現(xiàn)在的關系,與表示過去的時間狀語連用。現(xiàn)在完成時強調與現(xiàn)在的關系、對現(xiàn)在的影響,不能與表示過去的時間狀語連用。
現(xiàn)在完成進行時(have/has been doing)。動作從過去開始,一直延續(xù)到現(xiàn)在。How long have you been collecting shells? Have you been skating for five hours?
