. 一般現在時的用法

時間狀語: every…, sometimes, at…, on Sunday
I leave home for school at 7 every morning.
2) 客觀真理,客觀存在,科學事實。
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中。
Pride goes before a fall. 驕者必敗。
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..
4) 現在時刻的狀態、能力、性格、個性。
I don』t want so much.
Ann Wang writes good English but does not speak well.
比較:Now I put the sugar in the cup.
I am doing my homework now.
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。再如:Now watch me, I switch on the current and stand back. 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。
2. 一般過去時的用法
1)在確定的過去時間里所發生的動作或存在的狀態。
時間狀語有:yesterday, last week, an hour ago, the other day, in 1982等。
Where did you go just now?
2)表示在過去一段時間內,經常性或習慣性的動作。
When I was a child, I often played football in the street.
Whenever the Browns went ring their visit, they were given a warm welcome.
3)句型:
It is time for sb. to do sth "到……時間了" "該……了"
It is time sb. did sth. "時間已遲了" "早該……了"
It is time for you to go to bed. 你該睡覺了。
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』
I』d rather you came tomorrow.
4) wish, wonder, think, hope 等用過去時,作試探性的詢問、請求、建議等。
I thought you might have some. 我以為你想要一些。
比較:
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。
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。
Did you want anything else?
I wondered if you could help me.
2)情態動詞 could, would.
Could you lend me your bike?
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。
Mother used not to be so forgetful.
Scarf used to take a walk. (過去常常散步)
be used to + doing: 對……已感到習慣,或"習慣於",to是介詞,後需加名詞或動名詞。

典型例題
---- Your phone number again? I ___ quite catch it.
---- It』s 69568442.
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。
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,在爭求意見時常用於第二人稱。
Which paragraph shall I read first.

3) be +不定式表將來,按計劃或正式安排將發生的事。
We are to discuss the report next Saturday.
4) be about to +不定式,意為馬上做某事。

6. be to和be going to
be to 表示客觀安排或受人指示而做某事。
be going to 表示主觀的打算或計劃。
I am to play football tomorrow afternoon. (客觀安排)
I』m going to play football tomorrow afternoon. (主觀安排)
7. 一般現在時表將來
1)下列動詞:come, go, arrive, leave, start, begin, return的一般現在時表將來。這主要用來表示在時間上已確定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus star? It stars in ten minutes.
2)倒裝句,表示動作正在進行,如:
Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3)在時間或條件句中。
When Bill comes (不是will come), ask him to wait for me.
I』ll write to you as soon as I arrive there.
4)在動詞hope, take care that, make sure that等後。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
11. 用於現在完成時的句型
1)It is the first / second time…. that…結構中的從句部分,用現在完成時。
It is the first time that I have visited the city.
It was the third time that the boy had been late.
2)This is the… that…結構,that 從句要用現在完成時.
This is the best film that I』ve (ever) seen.
這是我看過的最好的電影。
This is the first time (that) I』ve heard him sing. 這是我第一次聽他唱歌。
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
答案B. This is the first time 後面所加從句應為現在完成時,故選B。
(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。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中,從句要用完成時。
注意:非延續性動詞的否定形式可以與表示延續時間的狀語連用。即動作不發生的狀態是可以持續的。
(錯)I have received his letter for a month.
(對)I haven』t received his letter for almost a month.
12. 比較since和for
Since 用來說明動作起始時間,for用來說明動作延續時間長度。
I have lived here for more than twenty years.
I have lived here since I was born..
My aunt has worked in a clinic since 1949.
Some new oilfields have been opened up since 1976.
I have known Xiao Li since she was a little girl.
My brother has been in the Youth League for two years.
I have not heard from my uncle for a long time.
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。)
小竅門: 當現在完成時+一段時間,這一結構中,我們用下面的公式轉化,很容易就能排除非延續動詞在完成時中的誤使。
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.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
13. since的四種用法
1) since +過去一個時間點 (如具體的年、月、日期、鍾點、1980, last month, half past six)。
I have been here since 1989.
2) since +一段時間+ ago
I have been here since five months ago.
3) since +從句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4) It is +一段時間+ since從句
It is two years since I became a postgraate student.
被動語態的幾種類型
1)主語句中有一個賓語的被動語態,如:
He saw her in the shop yesterday.
She was seen in the shop yesterday.
2) 主語有兩個賓語的被動語態
Li Lei gave me a chemistry book.
I was given a chemistry book by Li Lei.
A chemistry book was given to me by Li Lei.
3)主動句中含賓語補足語的句子的被動語態
若賓語補足語是不帶to 的不定式,變為被動語態時,該不定式前要加"to"。此類動詞為
感官動詞:feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teacher made me go out of the classroom.
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground.
--> He was seen to play football on the playground.
若賓語補足語是帶to的不定式,那麼被動語態仍保留to:
Mother told me not to be late
I was told not to be late by mother.
5)情態動詞+ be +過去分詞,構成被動語態。
Coal can be used to proce electricity for agriculture and instry.
6)表示"據說"或"相信" 的片語
believe, consider, declare, expect, feel , report, say, see, suppose, think, understand
It is said that… 據說
It is reported that… 據報道
It is believed that… 大家相信
It is hoped that… 大家希望
It is well known that… 眾所周知
It is thought that… 大家認為
It is suggested that… 據建議
It is taken granted that… 被視為當然
It has been decided that… 大家決定
It must be remember that…務必記住的是
It is said that she will leave for Wuhan on Tuesday.
14. 延續動詞與瞬間動詞
1) 用於完成時的區別
延續動詞表示經驗、經歷; 瞬間動詞表示行為的結 果,不能與表示段的時間狀語連用。
He has completed the work. 他已完成了那項工作。 (表結果)
I』ve known him since then. 我從那時起就認識他了。(表經歷)
2) 用於till / until從句的差異
延續動詞用於肯定句,表示"做……直到……" 瞬間動詞用於否定句,表示"到……,才……"
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
1. You don』t need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本題後句強調對現在的影響,我知道她的模樣,你不用描述。再次,several times告知為反復發生的動作,因此用現在完成時。
2.---I』m sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的動作由過去開始,持續到現在,應用現
. 不定式作賓語

例句:
a. Father will not allow us to play on the street.
父親不讓我們在街上玩耍。
b. We believe him to be guilty.
我們相信他是有罪的。
Find 的特殊用法:
Find 後可用分詞做賓補,或先加形式賓語,再加形容詞,最後加帶to 的動詞不定式。find後也可帶一個從句。此類動詞還有get,have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例題:
The next morning she found the man ___ in bed,dead.
A. lying B. lie C. lay D. laying
答案:A.find的賓語後面,用分詞或分詞短語,起賓語補足語作用。現在分詞表達主動,也表達正在進行,過去分詞表達被動。
2) to + be 的不定式結構,作補語的動詞。
Acknowledge, believe, consider, think, declare(聲稱), discover, fancy(設想), feel find, guess, judge, imagine, know, prove, see(理解), show, suppose, take(以為), understand
We consider Tom to be one of the best students in our class.
我們認為湯姆是班上最好的學生之一。
典型例題
Charles Babbage is generally considered ___ the first computer.
A. to invent B. inventing C. to have invented D. having invented
答案:A. 由consider to do sth. 排除B、D。. 此句只說明發明這一個事實,不定式後用原形即可。而C為現在完成時,發明為點動詞一般不用完成時,且此處也不強調對現在的影響,因此不選C。
3) to be +形容詞
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean…
The book is believed to be uninteresting.
人們認為這本書沒什麼意思。

注意:1) 其他系動詞如,look,appear等也可用於此句型
2) 不定式作為句子成分時,動詞用單數形式。
3) 當不定式作主語的句子中又有一個不定式作表語時,不能用It is… to…的句型
(對)To see is to believe. 百聞不如一見。
(錯)It is to believe to see.
4. It』s for sb.和 It』s of sb.
1)for sb. 常用於表示事物的特徵特點,表示客觀形式的形容詞,如easy, hard, difficult, interesting, impossible等:
It』s very hard for him to study two languages. 對他來說學兩門外語是很難的。
2)of sb的句型一般用表示人物的性格,品德,表示主觀感情或態度的形容詞,如good, kind, nice, clever, foolish, right。
It』s very nice of you to help me. 你來幫助我,你真是太好了。
for 與of 的辨別方法:
用介詞後面的代詞作主語,用介詞前邊的形容詞作表語,造個句子。如果道理上通順用of,不通則用for。如:
You are nice. (通順,所以應用of)。
He is hard. (人是困難的,不通,因此應用for。)
3) 祁使句(Imperative Sentence)
祈使句往往是用來表示說話人的請求、命令、要求、建議,等等。祈使句的主語常被省略,因為這個主語很明確地是聽話人"you"。當然,有時為了強調或表示某種感情,句子也會帶上主語。
祈使句的謂語用動詞原形;它的否定形式是句首用Don't + 動詞原形,或是Not to + 動詞原形。例如:
Be quiet , please ! (大家)請安靜。
Stand up ! 起立!
Don't smoke in the office . 請不要在辦公室吸煙。
Don't be standing in the rain . 別站在雨里。
Not to be careless when you're driving a car . 開車時不要粗心大意。
4) 感嘆句(Exclamatory Sentence)
感嘆句表示說話人的喜悅、氣憤、驚訝等強烈的情緒。這類句子中,有很多是由What或How引起的。What 用來強調名詞,How則強調形容詞、副詞或動詞。這類句子的構成只需將所強調或是說,所感嘆的對象放到句首;句子無需倒裝,句子要用正常語序。 當然,如果不用這種句型,而句子(無論是那種句子)本身又表示了上述的種種情緒,那麼該句也就成了感嘆句。例如:
What a fine day it is today ! 今天天氣多好啊!
How fine it is today ! 今天天氣多好啊!
What a lovely son you have !你有個多可愛的兒子啊!
How lovely your son is ! 你的兒子多可愛
