㈠ 初中英語一般過去時的語法形式有哪幾種
一般過去時主要表示過去某時發生的動作或情況。可以從以下幾個方面來理解:
1)過去某個時間所發生的動作或存在的狀態。e.g. I bought a new shirt yesterday. He was a worker two years ago.
2)過去一段時間內,經常性或習慣性的動作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.
3)談到已故人的情況時多用過去時。e.g. Lu Xun was a great writer.
4)有些發生時間不是很清楚的情況,實際是過去發生的,也應用過去時態。e.g. What did you say?
另外,還可用過去時表示委婉的語氣。e.g. Could you lend me your pen?
其結構是"主語+動詞的過去式"。be動詞的過去式為was, were;行為動詞的過去式有規則變化和不規則變化兩種,規則變化有以下幾種情況:1)直接在動詞原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e結尾的動詞只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一個輔音字母的重讀閉音節,應先雙寫這個輔音字母,再加-ed. e.g. shop-----shopped; 4)以"輔音字母+y"結尾的動詞,先把y變成i,再加-ed. e.g. carry----carried; study------studied.有些動詞變過去式是不規則的,e.g. fly------flew; break-----broke; teach-----taught. 這些需要象生單詞一樣記住.
其句式變化分為兩種情況
1)含有be動詞的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980?
2)含有行為動詞的變否定句要在行為動詞前加助動詞didn't.,同時把動詞變成原形; 變一般疑問句,在句首加助動詞did,同時把動詞變成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?
其時間狀語為yesterday或由其構成的短語,e.g. yesterday morning; 由"last+時間"構成的短語, e.g. last year; 由"時間段+ago"構成的短語, e.g. three days ago; 另外,還有on the morning of Monday, just now等,以及一些表示過去時態的從句.注意,在賓語從句中主句為過去,一般從句也為過去.
㈡ 初中英語語法
定義
動名詞是一種兼有動詞和名詞特徵的非限定動詞。它可以支配賓語,也能被副詞修飾。動名詞有時態和語態的變化。
解釋:動詞的ing形式如果是名詞,這個詞稱動名詞。
一、動名詞的作用
動名詞具有名詞的性質,因此在句中可以作主語、表語、賓語、定語等。
1、作主語
Reading is an art. 讀書是一種藝術。
Climbing mountains is really fun. 爬山是真有趣。
Working in these conditions is not a pleasure but a suffer. 在這種工作條件下工作不是愉快而是痛苦。
動名詞作主語,有時先用it作形式主語,把動名詞置於句末。這種用法在習慣句型中常用。如:
It is no use/no good crying over spilt milk. 灑掉的牛奶哭也沒用。
It is a waste of time persuading such a person to join us. 勸說這樣的人加入真是浪費時間。
It was hard getting on the crowded street car. 上這種擁擠的車真難。
It is fun playing with children. 和孩子們一起玩真好。
There is no joking about such matters. 對這種事情不是開玩笑。
動名詞作主語的幾種類型
動名詞可以在句子中充當名詞所能充當的多種句子成分。在這里僅就動名詞在句子中作主語的情況進行討論。
動名詞作主語有如下幾種常見情況:
1. 直接位於句首做主語。例如:
Swimming is a good sport in summer.
2. 用 it 作形式主語,把動名詞(真實主語)置於句尾作後置主語。
動名詞做主語時,不太常用 it 作先行主語,多見於某些形容詞及名詞之後。例如:
It is no use telling him not to worry.
常見的能用於這種結構的形容詞還有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。
注意:important,essential,necessary 等形容詞不能用於上述結構。
3. 用於「There be」結構中。例如:
There is no saying when he'll come.很難說他何時回來。
4. 用於布告形式的省略結構中。例如:
No smoking ( =No smoking is allowed (here) ).
No parking.
5. 動名詞的復合結構作主語
當動名詞有自己的邏輯主語時,常可以在前面加上一個名詞或代詞的所有格,構成動名詞的復合結構(——這時,名詞或代詞的所有格做動名詞的邏輯主語)。動名詞的復合結構也可以在句中作主語。例如:
Their coming to help was a great encouragement to us.
6.例詞
shopping fishing cycling這些都是很常見的動名詞
二、動名詞作主語與動詞不定式作主語的比較
動詞不定式和動名詞都可以用作主語。在意義上相近。但動名詞多用來表示泛指或抽象動作,不定式多用來表示特指或具體動作。比較:
Smoking is not good for health.
It is not good for you to smoke so much.
注意:
1)在口語中,用動名詞作主語位於句首的較不定式多見。
2)在「It is no use...」,「It is no good...」,「It is fun...」,「It is a waste of time...」等句型中,通常用動名詞作真實主語:
It is no use/good/a waste of time talking about that.
*It is no use/good/a waste of time to talk about that.
3)在疑問句中,通常用動名詞的復合結構,而不用不定式的復合結構作主語:
Does your saying that mean anything to him?
*Does for you to say that mean anything to him?
4)在「There be」句型中,只能用動名詞,而不能用不定式作主語:
There is no telling what will happen.
It is impossible to tell what will happen.
5)當句子中的主語和表語都是非限定動詞時,要遵循前後一致的原則,主語和表語在形式上要求統一:
Seeing is believing.
*To see is to believe.
2、作賓語
(1)作動詞的賓語
某些動詞後出現非限定性動詞時只能用動名詞作賓語,不能用不定式。常見的此類動詞有:advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, practise, resist, suggest, depend on, think about, set about, succeed in, worry about, burst out, insist on, can』t stand, be used to, get used to, devote…to…, look forward to, pay attention to, get down to等。如:
They went on walking and never stopped talking. 他們繼續走,說個不停。
I found it pleasant walking along the seashore. 在海灘上走真是樂事。
(2)作介詞的賓語
We are thinking of making a new plan for the next term. 我們正考慮為下學期制定新的計劃。
Shall we have a rest or get down to doing our work? 我們休息呢還是開始幹活?
(3)作形容詞的賓語
The music is well worth listening to more than once. 這種曲子很值得多聽幾遍。
We are busy preparing for the coming sports meet. 我們正為馬上到來的運動會忙著做准備。
3、作表語
動名詞作表語時句子主語常是表示無生命的事物的名詞或what引導的名詞性從句。表語動名詞與主語通常是對等的關系,表示主語的內容,主語、表語可互換位置。
Your task is cleaning the windows. 你的任務就是擦窗戶。(Cleaning the windows is your task.)
What I hate most is being laughed at. 我最痛恨的就是被別人嘲笑。 (Being laughed at is what I hate most.)
4、作定語
動名詞作定語往往表示被修飾詞的某種用途。如:
a walking stick =a stick for walking=a stick which is used for walking
a washing machine=a machine for washing=a machine which is used for washing
a reading room=a room for reading=a room which is used for reading
a measuring tape=a tape for measuring=a tape which is used for measuring
sleeping pills=pills for sleeping=pills which is used for sleeping
二、動名詞的邏輯主語
帶有邏輯主語的動名詞稱為動名詞的復合結構。當動名詞的邏輯主語與句子的主語不一致時,要在動名詞之前加上物主代詞或名詞所有格,這便構成了動名詞的復合結構。其中物主代詞(名詞所有格)是邏輯上的主語,動名詞是邏輯上的謂語。動名詞復合結構在句中可作主語、賓語、表語等,分別相當於一個主語從句、賓語從句、表語從句。如:
Her coming to help encouraged all of us. 他來幫忙鼓舞了我。 (=That she came to help encouraged all of us.)
Jane』s being careless caused so much trouble. 簡這么粗心惹來了不少麻煩。 (=That Jane was careless caused so much trouble.)
What』s troubling them is their not having enough food. 煩擾他們的是食物不足。 (=What』s troubling them is that they have not enough food.)
在口語中,如果動名詞復合結構作賓語,其中的物主代詞常用人稱代詞賓格,名詞所有格常用名詞普通格來代替,但在句首作主語時不能這樣來代替。如:
Would you mind my/me using your computer? 用下你的電腦介意嗎?
The father insisted on his son』s/his son going to college. 爸爸堅決要求兒子上大學。
Mary』s (不可用Mary) being ill made her mother upset. 瑪麗病了,使她媽媽很著急。
His (不可用Him)smoking made his family angry. 他抽煙使他一家人非常生氣。
在下列情況下動名詞的邏輯主語必須用名詞的普通格或人稱代詞賓語:
a.無命名詞
The baby was made awake by the door suddenly shutting. 這個嬰兒被猛烈的關門聲吵醒。
b. 有生命名詞但表示泛指意義
Have you ever heard of women practising boxing? 你聽說過婦女練拳擊嗎?
c. 兩個以上的有生命名詞並列
Do you remember your parents and me telling about this? 你記得你父母和我都告訴過你這事嗎?
三、動名詞的時態和語態
動名詞的時態和語態如下:
時態
主動語態
被動語態
一般式
writing
being written
完成式
having written
having been written
其否定形式是在doing前加上not
1、動名詞一般式表示的動作通常是一般性動作,即不是明確地發生在過去、現在或將來的動作,或是與謂語動詞所表示的動作同時發生的動作。如:
I hate talking with such people. 我討厭與這樣的人說話。
Being careless is not a good habit. 粗心不是一個好習慣。
2、動名詞的完成式表示的動作發生在謂語動詞動作之前。如:
I don』t remember having met him before. 我記不得以前見過他。
Thank you for having taking so much trouble to help. 謝謝你費力幫忙。
3、動名詞的邏輯主語同時也是動名詞動作的承受者,動名詞用被動語態。
(1)它的一般式表示的動作與謂語動詞動作同時發生,或在其前發生。如:
I don』t like being laughed at in public. 在公共場合下,我不喜歡被別人嘲笑。
(2)它的完成式表示的動作發生在謂語動詞之前。如:
I am very pleased at your having been honoured with a medal. 我很高興你能獲得這樣的獎牌。
(3)在某些動詞,我們常用動名詞的一般式表示完成式,盡管動作發生在謂語動詞動作之前,這似乎是一種強大的習慣。如:
Excuse me for being late. 我來晚了請你原諒。
I don』t remember ever meeting somewhere. 我記不得原來在什麼地方見過。
Thank you for giving us so much help. 謝謝給我們這么大的幫助。
(4)在多數情況下都避免使用動名詞被動語態完成式,而用一般式代替,以免句子顯得累贅,尤其是在口語中。如:
I forget once being taken (having been taken ) to the city zoo. 我曾被帶到過這個動物園,可我忘了。
(5)動名詞被動語態一般式與現在分詞被動語態一般式同形,但無進行意義,being不可省略。如:
She is afraid of being taken to the public. 她怕被領到大眾面前。
四、常見題型:
1) 動名詞做主語時,謂語動詞為單數
2) 在動名詞和不定式中,作為介詞的賓語是動名詞
3) 動名詞的否定直接在其前加否定詞,通過代詞的賓格或所有格形式給出邏輯主語
例:
I would appreciate_______ back this afternoon.
A.you to call B.you call C.you calling D.you』re calling(Key:C;換成your calling也對)
4) 有些詞後只能接動名詞
admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can』t help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...
5) 另外還有一些接-ing形式的常用說法
it』s no good; it』s no/little/hardly any/ use; it』s not/hardly/scarcely use; it』s worthwhile; spend money/time; there』s no; there』s no point in; there』s nothing worse than; what』s the use/point...
6) 有些詞後面加不定式和動名詞均可
remember, forget, try, stop, go on, cease, mean後面均可用不定式和-ing形式,但意義截然不容。
例:
remember to do/doing:
①I remembered to post the letters.(指未來/過去未來將要做的動作)
②I remembered posting/having posted the letters.(我記得做過這個動作)
forget與remember的用法類似。
regret的用法:
①I regret to inform you that…(我很遺憾地通知你……)
②I regretted having left the firm after twenty years.(為了「二十年前的離開」而遺憾。)
try to(努力)與try +–ing(試驗):
①You really must try to overcome your shyness.
②Try practicing five hours a day.
五、動名詞與現在分詞的同與不同
動名詞它在形式上與現在分詞相同,都是在動詞原形的詞末加-ing。在現代語法中,這兩種形式同視為"-ing形式"。 這兩種形式的另一個相同之處是:它們都是由動詞變化而成的,它們都保留了動詞的某些特徵,它們都能帶自己的賓語、狀語,而構成動名詞短語或是現在分詞短語去擔當句子成分。例如:
Speaking in the public , he will surely be very cheerful .
(現在分詞短語,作狀語)他在公眾場所講話時總是興高采烈的。
She hates speaking in the public.
(動名詞短語,作賓語)她不喜歡在公眾場所講話。
區別:
1、動名詞和現在分詞都可以用於系動詞之後作表語,區別方法是:
①作表語的動名詞與主語指的是同一件事,此時系動詞相當於「是」,通常把主語和表語的位置互換,語法和意思不變,例如:
My hobby is swimming.可改為Swimming is my hobby.(可將原句中的主語與表語位置互換)
②現在分詞作表語主要用以說明主語的性質,不能與主語互換位置,例如:
The story is interesting .不可改為:Interesting is the story.
2、動名詞和現在分詞都可以用作定語來修飾名詞,兩者的區別在於:
動名詞修飾名詞時主要表示該名詞的用途,而現在分詞修飾名詞時性質、狀態或動作等。試比較:
①a swimming boy和a swimming suit
前者的意思是「一個正在游泳的男孩」,即a boy who is swimming ,現在分詞swimming 表示被修飾名詞boy的動作;而後者的意思是「游泳衣」,即a suit for swimming , 動名詞swimming表示suit 的用途。
②a sleeping child 和 a sleeping car
前者的意思是「一個正在睡覺的孩子」,即a child who is sleeping ,現在分詞sleeping 表示被修飾名詞 child 正處於的狀態;而後者的意思是「卧車(被用來睡覺的車廂)」,即 a car which is used for sleeping ,動名詞 sleeping 表示car 的用途。
被動語態
一、 被動語態的用法:
1. 一般現在時的被動語態構成:is / am / are + 及物動詞的過去分詞
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
2. 一般過去時的被動語態構成:was / were + 及物動詞的過去分詞
A new shop was built last year.
Dinosaur eggs were laid long long ago.
3. 現在完成時的被動語態構成:has / have + been + 及物動詞的過去分詞
This book has been translated into many languages.
Many man-made satellites have been sent up into space by many countries.
4. 一般將來時的被動語態構成:will+ be + 及物動詞的過去分詞
A new hospital will be built in our city.
Many more trees will be planted next year.
5. 含有情態動詞的被動語態構成:情態動詞+ be + 及物動詞的過去分詞
Young trees must be watered often.
Your mistakes should be corrected right now.
The door may be locked inside.
Your homework can be handed in tomorrow.
6. 現在進行時的被動語態構成:am / is / are + being + 及物動詞的過去分詞
Uncle Wang is mending my bike now.→
My bike is being repaired by Tom now.
They are planting trees over there. →
Trees are being planted over there by them.
7. 不定式的被動語態:to + be + 及物動詞的過去分詞
There are two books to be read. →
There are twenty more trees to be planted.
二、 怎樣把主動語態改成被動語態?
把主動語態改為被動語態非常簡單,可以遵循以下幾個步驟:
1. 先找出謂語動詞;
2. 再找出謂語動詞後的賓語;
3. 把賓語用作被動語態中的主語;
4. 注意人稱、時態和數的變化。
例:1. Bruce writes a letter every week. →A letter is written by Bruce every week.
2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
3. He has written two novels so far.→Two novels have been written by him so far.
4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5. Lucy is writing a letter now.→A letter is being written by Lucy now.
6. You must lock the door when you leave.→the door must be locked when you leave.
三、 使用被動語態應注意的幾個問題:
1. 不及物動詞無被動語態。
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2. 有些動詞用主動形式表示被動意義。
This pen writes well.
This new book sells well.
3. 感官動詞或使役動詞使用省略to的動詞不定式,主動語態中不帶to ,但變為被動語態時,須加上to 。
例:make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4. 如果是接雙賓語的動詞改為被動語態時,直接賓語(物)作主語,那麼動詞後要用介詞,這個介詞是由與其搭配的動詞決定,或是間接賓語加被動語態再加只接賓語。
He gave me a book.→A book was given to me by him. 或是I was given a book by him.
He showed me a ticket.→A ticket was shown to me by him. 或是i was shown a ticket by him.
My father bought me a new bike. →A new bike was bought for me by my father. 或是Lwas bought a new bike by my father.
5. 一些動詞短語用於被動語態時,動詞短語應當看作一個整體,而不能丟掉其中的介詞或副詞。
We can』t laugh him. →He can』t be laugh by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.</CA>
㈢ 初中英語語法講解:"動詞+one's+過去分詞"的結構
這種結構是「動詞+one's+動名詞」,不是「動詞+one's+過去分詞」
其實從實質上看這只是動名詞回的用法,而不一定是用答在動詞後面。
因為動名詞具有名詞的性質,所以名詞可以作的成分,動名詞也可以作。名詞可以作動詞的賓語,因而動名詞也可以作動詞的賓語。物主代詞只是動名詞的邏輯主語,再說物主代詞也可以修飾名詞(如上所說的動名詞具有名詞的性質)。
這樣的用法很普遍。
如:I am sorry for my being late.
Lily felt shamed of her .
He disliked her working late.
㈣ 初中英語語法,例如被動語態,現在過去時。現在進行時和感嘆句
被動語態:一般兩種情況下用:不知道 或者不在乎誰是動作的實施者。將賓語做句子的主語,而謂語改成「be+動詞的過去分詞形式」,動作的實施者如果要提及的話,就用介詞by來引導出來。 如:主動句:i feed my dog everyday (我每天都喂我的狗) 被動句:my dog is fed everyday (by me)-----is fed 就是「be+動詞的過去分詞形式」。 還有一種被動式是用「get 「如:have you got your hair done? 你把你的頭發弄了一下嗎?其實在中文中就是 「把」字句。但是也是用動詞的過去分詞形式「done」。 過去進行時:動作分長短。一個相對長一點的動作(walking,waiting,working)發生在過去。 如: I was working on last saturday / you were standing there. 一般來說,過去進行時大部分都是用來襯托另外一個過去動作的。如:I was working on last saturday when you called me / you were standing there when the accident happened. 有時也故意用來強調:i was waiting for you for 2 hours. 過去完成時:一個動作在過去的過去就已開始的動作。 i have stayed in China for 2 years when i came here.----came 是過去的動作,stayed 是「過去的過去」。stayed這個動作結束於came發生的那個時刻。動作也有可能在過去的時段里繼續:i have stayed in China before my parents moved here. parents "moved" 後,我繼續呆在中國。 用過去完成時可以表示在一個動作完成以後,兩一個動作才開始。從而使兩個動作在時間上有比較,又獨立開來。 感嘆句: 由what 和how 來引導。 what: 1 what a /an +形容詞+可數名詞單數+(主謂部分)-----what a lovely boy (he is) 2 what +形容詞+不可數名詞or可數名詞復數+(主謂部分)-----what nice weather (it is) 3 what +a/ an+ 可數名詞單數:what a day! how: 1 How+主謂部分(謂語為實意動詞)--How she cries!! 2 How+形容詞+a /an +可數名詞單數+主謂部分----how lovely a boy he is. 3 how+形容詞或副詞+主謂部分------How lovely the boy is!
㈤ 初中英語語法 一般過去式和現在完成時區別練習
1、Both his parents look sad .Maybe they _________what's happened to him .
A. knew B. have known C. must know D.will know
答案 是 B . 因為原句中 Maybe 以表示「推測」, 用完成時表示對現在造成的「影響和結果」。 注意: 不要誤選答案 C. 因為,文中並不強調「過去」 的意義。
2、He has _______ been to Shanghai , has he ?
A. already B.never C.ever D. still
選擇 B.never 。 因為這是個反義疑問句的結構, 且後邊用的是「has he 」, 即肯定疑問式, 根據反義疑問句構成的「前肯後否, 前否後肯」原則, 可知, 前面一定是「否定句」, 只有選項 B never 填入句中,才能構成否定句。 所以, 正確答案是 B.
3、Have you met Mr Li ______?
A. just B. ago C.before D. a moment ago
選擇 C.before 這是個現在完成時的結構, 選項 A. just B. ago D. a moment ago 都是一般過去時的時間狀語, 所以,都不對。 只有 C before 才能用在現在完成時的句子中。 因此, 正確的答案 是 C 。
4、The famous writer _____ one new book in the past two year
A. is writing B.was writing C.wrote D.has written
正確答案是 D 。
句子意思是:在過去的兩年裡, 這位著名的作家寫了一本新書。
in the past two year 意思是 在過去的兩年裡, 也包含「現在」, 因此, 屬於現在完成時的范疇。 所以, 要選擇現在完成時的答案。
5、-Our country ______ a lot so far .

我是轉載的 看看吧:
11. 動詞的時態
11.1 一般現在時的用法
1) 經常性或習慣性的動作,常與表示頻腮度的時間狀語連用。時間狀語: every…, sometimes, at…, on Sunday。例如:
I leave home for school at 7 every morning. 每天早上我七點離開家。
2) 客觀真理,客觀存在,科學事實。例如:
The earth moves around the sun. 地球繞太陽轉動。
Shanghai lies in the east of China. 上海位於中國東部。
3) 表示格言或警句。例如:

注意:此用法如果出現在賓語從句中,即使主句是過去時,從句謂語也要用一般現在時。
例:Columbus proved that the earth is round. 哥倫布證實了地球是圓的。
4) 現在時刻的狀態、能力、性格、個性。例如:
I don't want so much. 我不要那麼多。
Ann writes good English but does not speak well. 安英語寫得不錯,講的可不行。
比較:Now I put the sugar in the cup. 把糖放入杯子。
I am doing my homework now. 我正在做功課。
第一句用一般現在時,用於操作演示或指導說明的示範性動作,表示言行的瞬間動作。第二句中的now是進行時的標志,表示正在進行的動作的客觀狀況,所以後句用一般現在時。

It is time that sb. did sth. "時間已遲了" "早該……了" ,例如It is time you went to bed. 你早該睡覺了。
would (had) rather sb. did sth. 表示'寧願某人做某事'。例如:I'd rather you came tomorrow.還是明天來吧。
4) wish, wonder, think, hope 等用過去時,作試探性的詢問、請求、建議等,而一般過去時表示的動作或狀態都已成為過去,現已不復存在。例如:I thought you might have some. 我以為你想要一些。
比較:Christine was an invalid all her life.(含義:她已不在人間。)
Christine has been an invalid all her life.(含義:她現在還活著)
Mrs. Darby lived in Kentucky for seven years. (含義:達比太太已不再住在肯塔基州。)
Mrs. Darby has lived in Kentucky for seven years. (含義:現在還住在肯塔基州,有可能指剛離去)
注意: 用過去時表示現在,表示委婉語氣。
1)動詞want, hope, wonder, think, intend 等。例如:
Did you want anything else? 您還要些什麼嗎?
I wondered if you could help me. 能不能幫我一下。
2)情態動詞 could, would。例如:

11.3 used to / be used to
used to + do:"過去常常"表示過去習慣性的動作或狀態,但如今已不存在。例如:
Mother used not to be so forgetful. 老媽過去沒那麼健忘。

A. didn't B. couldn't C. don't D. can't
答案A. 本句雖沒有明確的時間狀語,但從語意上看出,在聽的時候沒有聽懂這個動作發生在過去,因此應用過去時。
返回動詞的時態目錄
11.4 一般將來時
1) shall用於第一人稱,常被will 所代替。will 在陳述句中用於各人稱,在徵求意見時常用於第二人稱。例如:

返回動詞的時態目錄
11.10 比較一般過去時與現在完成時
1)一般過去時表示過去某時發生的動作或單純敘述過去的事情,強調動作;現在完成時為過去發生的,強調過去的事情對現在的影響,強調的是影響。
2)一般過去時常與具體的時間狀語連用,而現在完成時通常與模糊的時間狀語連用,或無時間狀語。
一般過去時的時間狀語:yesterday, last week,…ago, in1980, in October, just now等,皆為具體的時間狀語。
現在完成時的時間狀語:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不確定的時間狀語。
共同的時間狀語:this morning, tonight, this April, now, already, recently, lately 等。
3)現在完成時可表示持續到現在的動作或狀態,動詞一般是延續性的,如live, teach, learn, work, study, know.。
一般過去時常用的非持續性動詞有come, go, leave, start, die, finish, become, get married等。例如:
I saw this film yesterday. (強調看的動作發生過了)
I have seen this film. (強調對現在的影響,電影的內容已經知道了)
Why did you get up so early? (強調起床的動作已發生過了)
Who hasn't handed in his paper? (強調有卷子未交,疑為不公平競爭)
He has been in the League for three years. (在團內的狀態可延續)

2)This is +形容詞最高級+that…結構,that 從句要用現在完成時。例如:

典型例題
(1) ---Do you know our town at all?
---No, this is the first time I ___ here.
A. was B. have been C. came D. am coming

(2) ---Have you ____ been to our town before?
---No, it's the first time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意為曾經或無論何時,反意詞為never,此兩詞常用於完成時。

Since 用來說明動作起始時間,for用來說明動作延續時間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:並非有for 作為時間狀語的句子都用現在完成時。
I worked here for more than twenty years. (我現在已不在這里工作。)
I have worked here for many years.(現在我仍在這里工作。)
注意:用句型轉換的方法,很容易排除非延續動詞在有for/since結構的完成時中的誤用。
1)(對) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(錯) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.

He didn't come back until ten o'clock. 他到10 點才回來。
He slept until ten o'clock. 他一直睡到10點。
典型例題

A. had written, left B,were writing, has left C. had written, had left D. were writing, had left
答案D. "把書忘在辦公室"發生在"去取書"這一過去的動作之前,因此"忘了書"這一動作發生在過去的過去,用過去完成時。句中when表示的是時間的一點,表示在"同學們正忙於……"這一背景下,when所引導的動作發生。因此前一句應用過去進行時。
注意: had hardly… when 還沒等…… 就……。例如:
I had hardly opened the door when I he hit me. 我剛打開門,他就打了我。
had no sooner…than 剛…… 就……。例如:
He had no sooner bought the car than he sold it. 他剛買了這輛車,轉眼又賣了。
