I. 時間狀語從句的引導詞都有什麼啊
狀語
狀語是修飾語,一般不作句子成分.一般修飾動詞,可以是詞語也可以是句子.狀語是用來修飾謂語的.比如時間狀語,地點狀語,條件狀語之類的.狀語:用於修飾動詞、形容詞、副詞或整個句子。通常表示行為發生的時間、地點、目的、方式、程度等。狀語一般由副詞、介詞短語、分詞和分詞短語、不定式或相當於副詞的詞或短語來擔當。其位置一般放在句末,但也可放在句首或句中。
19.1 地點狀語從句
地點狀語從句通常由where, wherever 引導。
Where I live there are plenty of trees.
我住的地方樹很多。
Wherever I am I will be thinking of you.
不管我在哪裡我都會想到你。
19.2 方式狀語從句
方式狀語從句通常由as, (just) as…so…, as if, as though引導。
1) as, (just) as…so…引導的方式狀語從句通常位於主句後,但在(just) as…so…結構中位於句首,這時as從句帶有比喻的含義,意思是"正如…","就像",多用於正式文體,例如:
Always do to the others as you would be done by.
你希望人家怎樣待你,你就要怎樣待人。
As water is to fish, so air is to man.
我們離不開空氣,猶如魚兒離不開水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打掃房屋一樣,我們也要掃除我們頭腦中落後的東西。
2) as if, as though
兩者的意義和用法相同,引出的狀語從句謂語多用虛擬語氣,表示與事實相反,有時也用陳述語氣,表示所說情況是事實或實現的可能性較大。漢譯常作"彷彿……似的","好像……似的",例如:
They completely ignore these facts as if (as though) they never existed.
他們完全忽略了這些事實,就彷彿它不存在似的。(與事實相反,謂語用虛擬語氣。)
He looks as if (as though) he had been hit by lighting.
他那樣子就像被雷擊了似的。(與事實相反,謂語用虛擬語氣。)
It looks as if the weather may pick up very soon.
看來天氣很快就會好起來。(實現的可能性較大,謂語用陳述語氣。)
說明:as if / as though也可以引導一個分詞短語、不定式短語或無動詞短語,例如:
He stared at me as if seeing me for first time.
他目不轉睛地看著我,就像第一次看見我似的。
He cleared his throat as if to say something.
他清了清嗓子,像要說什麼似的。
The waves dashed on the rocks as if in anger.
波濤沖擊著岩石,好像很憤怒。
19.3 原因狀語從句
比較:because, since, as和for
1) because語勢最強,用來說明人所不知的原因,回答why提出的問題。當原因是顯而易見的或已為人們所知,就用as或 since。
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2) 由because引導的從句如果放在句末,且前面有逗 號,則可以用for來代替。但如果不是說明直接原因,而是多種情況加以推斷,就只能用for。
He is absent today, becaus e / for he is ill.
He must be ill, for he is absent today.
19.4 目的狀語從句
表示目的狀語的從句可以由that, so that, in order that, lest, for fear that, in case等詞引導,例如:
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
19.5 結果狀語從句
結果狀語從句常由so… that 或 such…that引導,掌握這兩個句型,首先要了解so 和 such與其後的詞的搭配規律。
比較:so和 such
其規律由so與such的不同詞性決定。such 是形容詞,修飾名詞或名詞片語,so 是副詞,只能修飾形容詞或副詞。 so 還可與表示數量的形容詞many, few, much, little連用,形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
( so many 已成固定搭配,a lot of 雖相當於 many,但 a lot of 為名詞性的,只能用such搭配。)
so…that與such…that之間的轉換既為 so與such之間的轉換。
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
19.6 條件狀語從句
連接詞主要有 if, unless, as/so long as, on condition that 等。.
if 引導的條件句有真實條件句和非真實條件句兩種。非真實條件句已在虛擬語氣中闡述。
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例題
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A。 句意:除非你立即走,否則你就回遲到的。可轉化為 If you dong leave immediately, you will be late. B、D句意不對,or表轉折,句子如為 You leave immediately or you will be late.
19.7 讓步狀語從句
though, although
注意: 當有though, although時,後面的從句不能有but,但是 though 和yet可連用
Although it's raining, they are still working in the field.
雖然在下雨,但他們仍在地里幹活。
He is very old, but he still works very hard.
雖然他很老,但仍然努力地工作。
Though the sore be healed, yet a scar may remain.
傷口雖癒合,但傷疤留下了。 (諺語)
典型例題
1) ___she is young, she knows quite a lot.
A. When B. However C. Although D. Unless
答案:C。意為雖然她很年輕,卻知道許多。
2) as, though 引導的倒裝句
as / though引導的讓步從句必須表語或狀語提前(形容詞、副詞、分詞、實義動詞提前)。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意: a. 句首名詞不能帶任何冠詞。
b. 句首是實義動詞,其他助動詞放在主語後。如果實義動詞有賓語和狀語,隨實義動詞一起放在主語之前。
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
雖然他盡了努力,但他的工作總做的不盡人意。
3) ever if, even though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑問詞" 或"疑問詞+後綴ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替換:no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意:no matter 不能引導主語從句和賓語從句。
(錯)No matter what you say is of no use now.
(對)Whatever you say is of no use now.
你現在說什麼也沒用了。(Whatever you say是主語從句)
(錯)Prisoners have to eat no matter what they're given,
(對)Prisoners have to eat whatever they're given. 囚犯們只能給什麼吃什麼。
19.8 比較while, when, as
1)as, when 引導短暫性動作的動詞。
Just as / Just when / When I stopped my car, a man came up to me.
2)當從句的動作發生於主句動作之前,只能用when 引導這個從句,不可用as 或 while。
When you have finished your work, you may have a rest.
3)從句表示"隨時間推移"連詞能用as,不用when 或while。
As the day went on, the weather got worse.
日子一天天過去,天氣越變越壞。
19.9 比較until和till
此兩個連詞意義相同。肯定形式表示的意思是"做某事直至某時",動詞必須是延續性的。否定形式表達的意思是"直至某時才做某事"。動詞為延續性或非延續性都可 以。 正確使用這兩個連詞的關鍵之一就在於判斷句中的動詞該用肯定式還是否定式。
肯定句:
I slept until midnight. 我一直睡到半夜時醒了。
Wait till I call you. 等著我叫你。
(在肯定句中可用before代替 Let's get in the wheat before the sun sets.)
否定句:
She didn't arrive until 6 o'clock.
她直到6點才到。
Don't get off the bus until it has stopped.
公共汽車停穩後再下車。
I didn't manage to do it until you had explained how. 直到你教我後,我才會做。
1)Until可用於句首,而till通常不用於句首。
Until you told me, I had heard nothing of what happened.
直到你告訴我以前,出了什麼事我一點也不知道。
2)Until when 疑問句中,until要放在句首。
---Until when are you staying? 你呆到什麼時候?
--- Until next Monday. 呆到下周一。
注意:否定句可用另外兩種句式表示。
(1)Not until …在句首,主句用倒裝。
Not until the early years of the 19th century did man know what heat is.
直到19 世紀初,人類才知道熱能是什麼。
Not until I began to work did I realize how much time I had wasted.
直到我開始工作,我才認識到了我已蹉跎了幾多歲月。
(2) It is not until… that…
19.10 表示"一…就…"的結構
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示"一…就…"的意思,例:
I had hardly / scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, it began to rain.
注意:如果hardly, scarcely 或no sooner置於句首,句子必須用倒裝結構:
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.
情態動詞
情態動詞 (Model Verbs) 又稱為情態助動詞 (Model Auxil-iaries)。英語中助動詞主要有兩類:一是基本助動詞,如have, do, be;二是情態助動詞,如may, must, need等。情態動詞與其他動詞連用表示說話人的語氣。情態動詞可表達建議、要求、可能和意願等。情態動詞沒有人稱和數的變化。在大學英語四、六級考試中,情態動詞部分重點測試以下內容:
(1)情態動詞+行為動詞完成式
(2)情態動詞+行為動詞進行式
(3)情態動詞+行為動詞完成進行式
(4)某些情態動詞的特殊用法
一、情態動詞+行為動詞完成式
情態動詞+行為動詞完成式即「情態動詞+ have + v-ed分詞」,表示對過去行為或動作進行推測、評論或判斷。
1. must have v-ed
must have v-ed 表示推測過去某事「一定」發生了。其否定形式為:can』t / couldn』t have v-ed, 表示過去不可能發生某事。例如:
1)Since the ditch is full of water, it must have rained last night.
2)You couldn』t have met my grandmother. She died before you were born.
2. could have v-ed
could have v-ed 表示推測過去某動作「很可能」發生了。例如:
1)「The dictionary has disappeared. Who could have taken it?」
2)「Tom could have taken it. He was alone yesterday.」
3.may / might have v-ed
may / might have v-ed 表示推測過去某事「也許」發生了.may 比 might 表示的可能性在說話人看來稍大些。例如:
I can』t find my keys. I may / might have left them at the school yesterday.
4. ought to / should have v-ed 和 ought not to / shouldn』t have v-ed
ought to / should have v-ed 和 ought not to / shouldn』t have v-ed 用於對已發生的情況表示「責備」、「不滿」,分別表示「本應該…」和「本不應該…」。例如:
1)With all the work finished, I should have gone to the party last night.
2)You ought not to make fun of him. He is not the one you laugh at but learn from.
5. needn』t have v-ed
needn』t have v-ed 表示過去做了某事,但沒有做的必要, 意為「本沒必要…」。例如:
You needn』t have waken me up; I don』t have to go to work today.
註:表示推測過去某動作發生的可能性時,就表示的可能性程度而言,must最大,could其次,may更次之,might最小。例如:
「I wonder how Tom knew about your past.」
「He must / could / may / might have heard of it from Mary.」
二、情態動詞+行為動詞進行式
情態動詞+行為動詞進行式(即情態動詞+ be + v-ing形式),表示推測或評論某動作現在是否正在進行。例如:
1)He must be playing basketball in the room.
2)She may be staying at home.
三、情態動詞+行為動詞完成進行式
情態動詞+行為動詞完成進行式(即情態動詞+ have been + v-ing 形式),表示推測或評論過去某動作是否正在進行或一直在進行。例如:
1)They should have been meeting to discuss the problem.
2)He may / might have been buying stamps in the post office when you saw him.
四、某些情態動詞的特殊用法
1. need
考試中主要測試 need 作情態動詞與作實義動詞的區別,對此,可參見表1.need 作情態動詞時,後面跟不帶to 的動詞不定式,即 「need to」。通常用在疑問句和否定句中,表示詢問是否有「必要」,其否定形式為needn』t,表示「不必」;疑問形式為 Need … do? 極少用於肯定句。例如:
1)I don』t think we need turn the light on at that time.
2)Need you ride a bike to school?
情態動詞need與實義動詞need 在時態、肯定、否定結構上的對比見表1。
2. dare
考試中主要測試dare作情態動詞和作實義動詞的區別。
情態動詞dare 與實義動詞dare 在時態、肯定、否定、疑問結構上的對比見表2。
3. can 和 may
考試中主要測試can,may或could,might表示可能性的區別及對may構成的疑問句的回答。
時態 情態動詞need 實義動詞 need
現 You need (not) do You (don』t) need to do
在
時 He need (not) do He needs (doesn』t need) to do
過 You needed (didn』t need) to do
去
時 He needed (didn』t need) to do
將 You need (not) do You will (not) need to do
來
時 He need (not) do He will (not) need to do
句型 時態 動詞
情態動詞dare 實義動詞 dare
肯定句 現在時 dare to 少用 dare/dares to do
過去時 dare to 少用 dared to do
否定句 現在時 daren』t/dare not do do/does not dare (to) do
過去時 dared not do did not dare (to) do
疑問句 現在時 Dare he do? Do you/Does he dear (to) do?
過去時 Dared he do? Did he dare (to) do
(1)can, could, may, might都可以表示可能性.can, could表示潛在的可能性或理論上或邏輯判斷上存在的可能性;而may, might則表示事實上的可能性。此外,can還具有「有能力」的意思,而may與might則不具此意。例如:
1)According to the weather forecast, it may rain tomorrow.
2) Any man with a little sense can see that he is wrong.
(2)May I / we …?這一類疑問句的肯定回答為Yes, please.或Certainly;否定回答為Please don』t.或No, you mustn』t. 例如:
「May we leave now?」 「No, you mustn』t. You haven』t finished your home work yet.」
4. can 和 be able to
can 與 be able to 都可以表示能力,但兩者在用法上有點差異:can (could)表示主觀能力,不表示意願,它的將來時用will be able to; be able to表示主觀意願,強調要克服困難去做某事。例如:
1)My grandma is over seventy, but she can still read without glasses.
2)He is able to give up his bad habits.
5. must 和 have to
must 和 have to 都可以表示「必須」,但有幾點區別:
(1)must 強調「內在的職責」、「義務」,而have to 強調「外界壓力」、「不得已而為之」。
(2)have to可用於多種時態,而must一般用於現在時,其過去時與將來時分別由had to與shall / will have to代替。
(3)在回答must引起的問題時,如果是否定的答復,不能用mustn』t,而要用needn』t或don』t have to,因為mustn』t是「一定不要」、「一定不能」的意思。例如:
1)You must come to the classroom before eight.
2)It is raining hard outside, but I have to leave now.
3)「Must we do it now?」 「No, you needn』t.」
6. used to +v, be used to +v-ing和be used to +v
(1)used to +v意為「過去常常」,「過去一直」;be used to +v-ing / n(名詞)意為「習慣於」;be used to +v意為「被用來(做某事)」。
(2)used to只表示過去,而be used to +v-ing / n可表示現在、過去或將來。例如:
1)He used to smoke. Now he doesn』t.
2)He』s quite used to hard work / working hard.
3)The knife is used to cut bread.
7.用作情態動詞的其他短語
would rather, would sooner, would (just) as soon, had rather, had better, had sooner, can not but, may (just) as well等可用作情態動詞。例如:
1)The soldier would sooner die than surrender.
2)The brave soldier would as soon die as yield to such an enemy.
3)I』d rather walk than take a bus.
4)If you don』t like to swim, you may just as well stay at home.
註:這些短語後一般直接跟動詞原形.would (had) rather, would (had) sooner, would (just) as soon後可跟that 引導的從句,that 常省去,從句要用虛擬語氣。對現在和將來的假設用過去時,對過去的假設用過去完成時。例如:
1)I would rather you came on Sunday.
2)I would sooner you hadn』t asked me to speak yesterday.
J. 英語中,引導時間狀語從句的連接詞有哪些
所謂的時間狀語從句是指:用來修飾動詞、形容詞、副詞或整個句子的從句叫做狀語從句。1.由when,while,as引導的時間狀語從句。例如:Strikewhiletheironishot.趁熱打鐵。2.由before和after引導的時間狀語從句。例如:Afteryouthink
