第二篇：狀語從句

Clauses of Condition, Concession and Contrast(條件、讓步和對比從句)條件從句

由 if, unless, as(so)long as, provided / providing(that), suppose / supposing(that), in case等引導(dǎo)，如：

If he comes I'll tell you.You would have succeeded if you had tried harder.You will fail unless you work hard.(=You will fail if you don't work hard.)

Supposing / Suppose it rains, shall we have the match as scheduled?

In case you need anything else, please let me know.讓步從句

由 although, though, even though, even if, whether...or, while, as, wh-words + ever(= no matter + wh-words)等從屬連詞引導(dǎo)，如：

He is quite modest though he is the best student in the class.The needle has the same mass whether it is hot or cold.Whichever(No matter which)plan you adopt, you will meet with difficulties.使用上述讓步從句的某些從屬連詞時注意以下幾點：

a.although(though)不可與連詞 but 連用；

b.as 引導(dǎo)的從句意義和 though 相似，但表示的語氣較強，并須將強調(diào)的詞放在句首（但不用 although），如：

Simple as(though)the question may seem, it is not at all common in nature.c.however / no matter how 引導(dǎo)的從句中，however / no matter how 后須緊跟形容詞或副詞，如：

However / No matter how hard I tried, I couldn't remember all the questions.對比從句

表示兩個人或兩件事之間的對比，常用 while 或 whereas 引導(dǎo)，如：

He is idle, while his brother is diligent.Some people like fat meat, whereas others hate it.Clauses of Cause, Result and Purpose(原因、結(jié)果和目的從句)原因從句

主要由下列從屬連詞引導(dǎo)：

1． Because, as, since。其中 because 語氣最強，表示直接、主要原因，通常引導(dǎo)的從句放在句尾，特別是回答 why 提出的問題只能用 because;as 和 since 表示明顯的、已知的原因，since 比 as 正式，如：

They had to move because their building was to be pulled down.As Mary was the eldest, she looked after the others.Since they live near the sea, they often go sailing.2． now that, seeing(that), considering(that), in that。這些連詞與 as, since 意思相近，通常用于書面語，并且它們兼有其它意義。now that 有“時間”含義，表示”既然”，說明一種新

情況；seeing(that)和 considering(that)有“條件”含義；in that 有”某一方面”含義，如：

Now that you are well again you can travel.Seeing(that)they are just beginners, they are doing quite a good job.I was lucky in that I was able to find a good baby-sitter（保姆）.結(jié)果從句

常用 so that, so...that, such...that, that 等連詞引導(dǎo)，如：

I was caught in a shower, so that all my clothes got wet.I was so tired that I could hardly keep my eyes open.He was such a good runner that I couldn't catch him.目的從句

常用 so that, in order(that), lest, for fear that 等連詞引導(dǎo)，如：

I took a taxi so that I could be in time for the meeting.Come closer in order that you may see the blackboard better.so that 既可引導(dǎo)結(jié)果從句也可引導(dǎo)目的從句，但結(jié)果從句表示事實，通常不含情態(tài)動詞；目的從句表示希望或想要實現(xiàn)的事實，通常含有情態(tài)動詞，如：

He got up early so that he caught the train.（結(jié)果）

He got up early so that he could(might)catch the train.（目的）

Lest 和 for fear(that)含有否定意義，并且從句中動詞須用 “動詞原形”或 ”should + V.” 的虛擬語氣，如：

He ran away lest he(should)be caught.(= He ran away in order that he would not be caught.)

I checked all the results time and again for fear that there should be any mistakes.(= I checked all the results time and again so that there wouldn't be any mistakes.)

Clauses of Manner and Comparison(方式和比較從句)方式從句

主要由 just as, as, as if, as though 等連詞引導(dǎo)，如：

He doesn't speak the way as other people do.Our bodies are made up of millions of very small cells, just as a building is made of many stones or bricks.He speaks French as if(as though)he were a Frenchman.由 as if 或 as though 引導(dǎo)的從句通常用虛擬語氣，但如果主句謂語是感官動詞，并且所述情況實現(xiàn)可能性大，也可用陳述語氣，如：

It looks as if the coming autumn harvest will be even better than the last one.比較從句

主要由 as...as, not so(as)...as, than 等連詞引導(dǎo)，如：

This table is as wide as that one.Mary can not run so(as)fast as Tom.Silver conducts electricity better than other metals.Clauses of Proportion and Other Types(比例從句和其它從句)比例從句

由關(guān)聯(lián)詞 the...the...連接形容詞或副詞比較級構(gòu)成，如：

The more she thought about it, the more she liked it.其它從句

如 as...so 和 what...that 引導(dǎo)的類比從句；so(as)far as 引導(dǎo)的范圍從句；except that 引導(dǎo)的例外從句；rather / sooner than 和 would / had rather than 引導(dǎo)的擇比從句等，如：

As the desert is like a sea, so is the camel like a ship.（沙漠似海，駱駝似舟。）

What blood vessel is to a man's body, that railway is to transportation.（鐵路對于運輸，好比血管對于人的身體。）

As(So)far as I know, he is an honest man.（據(jù)我所知，他是一個誠實的人。）

I would do it with pleasure, except that I am too busy.（要不是我太忙了，我會很高興去做的。）

Rather than get money in such a dishonest way, he would beg in the streets.（他寧可沿街乞討，也不愿意用欺騙手段騙取錢。）

He would rather have the small one than the large one.（他寧可要那個小的，而不愿要那個大的。）

第四篇：狀語從句1

狀語從句

一：什么是狀語從句？

用一個句子(從句)來作另一個句子(主句)的狀語，用作狀語的句子就叫作狀語從句。作什么樣的狀語就叫什么類型的狀語從句。例如：條件狀語從句就是用一個句子來作條件狀語。二：狀語從句的分類。

1.時間狀語從句用法要點。

凡是從句都必須有引導(dǎo)詞，引導(dǎo)時間狀語從句的詞有 when, before, after, until, as soon as, while 等，具體用法如下：

（1）.when 意為“當(dāng)??時”，引導(dǎo)時間狀語從句，表示主句的動作和從句的動作同時或先后發(fā)生。例如：

I feel very happy when you come to see me.你（們）來看我時，我感到很高興。

When you are crossing the street, you must be careful.你（們）過街道時，一定要小心。when引導(dǎo)的時間狀語從句，when的從句可以用延續(xù)性動詞，也可以用點動詞。He was working at the table when I went in.當(dāng)我進(jìn)去的時候，他正在桌旁工作。Someone knocked at the door when I was sleeping.當(dāng)我正在睡覺時，有人敲門。I will visit my good friend when I have time.當(dāng)我有空兒時，我將去看望我的好友。I worked for a foreign company when I was in Shanghai.當(dāng)我在上海時，我為一家外國企業(yè)工作。

注：when也可以作并列連詞，表示一個動詞正在進(jìn)行的時候，突然間發(fā)生了另外一件事。

I was fishing by the river , when someone called for help.我正在河邊釣魚，就在那時有人求救。

We were working in the chemistry lab, when the lights went out.我們正在化學(xué)實驗室工作，突然燈都熄滅了。

比較while, when, as

1）as, when 引導(dǎo)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(dāng)從句的動作發(fā)生于主句動作之前，只能用when 引導(dǎo)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。

（2）.before 意為“在??之前”，引導(dǎo)時間狀語從句時，表示主句的動作發(fā)生在從句的動作之前。例如：

We cleaned the classroom before we left school yesterday.昨天離開學(xué)校之前，我們打掃了教室。

He had been a cook before he went to college.他上大學(xué)前曾當(dāng)過廚師。

after 意為“在??之后”，引導(dǎo)時間狀語從句時，表示主句的動作發(fā)生在從句的動作之后。例如：

After you use plastic bags, you mustn't throw them about.你（們）用過了塑料袋之后，不準(zhǔn)到處亂扔。

He called me after he had finished his work.他在工作完之后給我打了個電話。

注：若主句和從句兩個動作發(fā)生的先后順序十分接近，那么也可以不用完成時態(tài)，例如 1

上面的第二句可改成：He called me after he finished his work.（3）.since引導(dǎo)的時間狀語從句，譯為“自從??”，主句常用現(xiàn)在完成時，從句常用一般過去時。

We have made many dumplings since we began to cook.自從我們開始做飯起，我們已經(jīng)包了許多餃子了。

We haven't seen each other since we parted.我們自從分手以后一直沒見過面。

注：常用句型：It is +時間段+since從句譯為：自從??有多長時間了。

It is six years since she graduated from the university.自從她大學(xué)畢業(yè)已有六年的時間了。

（4）.until 意為“直到??時”，引導(dǎo)時間狀語從句時，表示主句的動作發(fā)生在從句的動作之前。當(dāng)主句的謂語動詞是持續(xù)性動詞時，主句常用肯定形式；當(dāng)主句的謂語動詞是非持續(xù)性動詞時，從句常用否定形式, not...until...意為“直到??才??”，這時的until可以用before 來替換。例如：

I'll stay here until you come back.我會呆在這里，直到你回來。(stay表示的動作可以持續(xù))

He didn't go to bed until he finished his homework.他直到做完作業(yè)才睡覺。(go to bed 表示的動作不能持續(xù))

（5）表示“一?就?”的結(jié)構(gòu)

hardly/scarcely?when/before, no sooner?than 和as soon as都可以表示“一?就?”的意思，表示從句的動作一發(fā)生，主句的動作馬上就發(fā)生。例：

①、I'll tell him about it as soon as he comes back.他一回來我就告訴他這件事。

②、I had hardly / scarcely got home when it began to rain.③、I had no sooner got home than it began to rain.④、As soon as I got home, it began to rain.注意：如果hardly, scarcely 或no sooner置于句首，句子必須用倒裝結(jié)構(gòu)：

Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain.（6）.while引導(dǎo)的時間狀語從句，常譯為“與??同時，在??期間”，while的從句中常用延續(xù)性動詞或表示狀態(tài)的詞。

They rushed in while we were discussing problems.當(dāng)我們正在討論問題時，他們沖了進(jìn)來。

Father was cleaning the car while I was playing computer games.當(dāng)我正在打電子游戲時，爸爸正在清洗汽車。

注：while也可以作并列連詞，表轉(zhuǎn)折的關(guān)系，相當(dāng)于but，譯為“然而”。eg.I like listening to music, while my brother likes doing sports.我喜歡聽音樂，而我的兄弟愛好運動。

（7）.till和until引導(dǎo)的時間狀語從句，譯為“直到??為止”，not ? till / until引導(dǎo)的時間狀語從句，譯為“直到??才”。前者強調(diào)主句動作的結(jié)束，用延續(xù)性動詞，后者強調(diào)主句動作的開始，用點動詞。

比較until和till

此兩個連詞意義相同?？隙ㄐ问奖硎镜囊馑际恰白瞿呈轮敝聊硶r”，動詞必須是延續(xù)性的。否定形式表達(dá)的意思是“直至某時才做某事”。動詞為延續(xù)性或非延續(xù)性都可以。正確使用這兩個連詞的關(guān)鍵之一就在于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(wěn)后再下車。

I didn't manage to do it until you had explained how.直到你教我后，我才會做。

1)Until可用于句首，而till通常不用于句首。

Until you told me, I had heard nothing of what happened.直到你告訴我以前，出了什么事我一點也不知道。

2)Until when 疑問句中，until要放在句首。

---Until when are you staying? 你呆到什么時候？

---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(jì)初，人類才知道熱能是什么。

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(rèn)識到了我已蹉跎了幾多歲月。

(2)It is not until? that?

I will wait for my friend until / till he comes.我要一直等到我朋友來。

We won't start our discussion until / till he comes.我們要等到他來了，再開始我們的討論。

2、地點狀語從句用法要點。

常用where（哪里）和wherever（無論哪里）引導(dǎo)。

Where there is a will, there is a way.有志者，事竟成。

We will go wherever the motherland need us most.我們要到祖國最需要的地方去。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.不管我在哪里我都會想到你。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(dǎo)。

1）as,(just)as?so?引導(dǎo)的方式狀語從句通常位于主句后，但在(just)as?so?結(jié)構(gòu)中位于句首，這時as從句帶有比喻的含義，意思是“正如?”，“就像”，多用于正式文體，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后的東西。

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?qū)崿F(xiàn)的可能性較大。漢譯常作“仿佛??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，就仿佛它不存在似的。（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(xiàn)的可能性較大，謂語用陳述語氣。）

說明：as if / as though也可以引導(dǎo)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(zhuǎn)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，像要說什么似的。

The waves dashed on the rocks as if in anger.波濤沖擊著巖石，好像很憤怒。原因狀語從句用法要點。

常用的引導(dǎo)連詞有because, as和since。三者的區(qū)別是：在回答問題的時候，使用because；對于顯而易見的原因，常用as或since；as和since的從句常放在主句之前，而because的從句常放在主句之后。

Why did you go?I went because Tom told me to go.你為何去？那是因為湯姆叫我去。He was angry not because we were late but because we made a noise.他很生氣不是因為我們來遲了，而是因為我們弄出了聲音。

As it was raining hard, we had to be indoors.由于雨太大，我們只好呆在家里。

Since you feel ill, you'd better not go to work.既然你感覺不舒服，你最好不要去上班了。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(dāng)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(dǎo)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, because / for he is ill.He must be ill, for he is absent today.5、目的狀語從句用法要點。

常用的引導(dǎo)連詞有so that, that和in order that譯為：以便，為了，目的是。此外還有l(wèi)est, for fear that, in case等詞引導(dǎo)，例如，Please speak more slowly so that we can make full notes.請講慢一點，以便我們能作詳細(xì)筆記。

I shall write down your address that I may not forget.我要把你的地址記下來，以免忘記。

I sent the letter by air mail in order that it might reach him in time.這封信我以航空信發(fā)出，以便他能及時收到。

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.注：目的狀語從句可以用動詞不定式來替換做目的狀語

We work harder than usualfinish it in a week.我們比平常加倍努力工作以在一周內(nèi)完

成工作。結(jié)果狀語從句

結(jié)果狀語從句常由so? that 或 such?that引導(dǎo)，掌握這兩個句型，首先要了解so 和 such與其后的詞的搭配規(guī)律。

比較：so和 such

其規(guī)律由so與such的不同詞性決定。such 是形容詞，修飾名詞或名詞詞組，so 是副詞，只能修飾形容詞或副詞。so 還可與表示數(shù)量的形容詞many, few, much, little連用，形成固定搭配。

so foolishsuch a fool

so nice a flowersuch a nice flower

so many / few flowerssuch nice flowers

so much / little money.such rapid progress

so many peoplesuch a lot of people

（so many 已成固定搭配，a lot of 雖相當(dāng)于 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(zhuǎn)換既為 so與such之間的轉(zhuǎn)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條件狀語從句用法要點。

我們主要看一下由if引導(dǎo)的條件狀語從句。if 意為“如果”，引導(dǎo)條件狀語從句時，表示假如有從句的動作發(fā)生就(不)會有主句的動作發(fā)生。例如：

If it doesn't rain tomorrow, we will go there by bike.如果明天不下雨，我們就騎自行車去那里。

If I get there early, I can see the doctor quickly.如果我早早地到那里，我就可以快點看病。連接詞主要有 if, unless, as/so long as, on condition that 等。.if 引導(dǎo)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.unlessB.untilC.ifD.or

答案A。句意：除非你立即走，否則你就回遲到的。可轉(zhuǎn)化為 If you dong leave immediately, you will be late.B、D句意不對，or表轉(zhuǎn)折，句子如為 You leave immediately or you will be late.8讓步狀語從句

though, although

注意： 當(dāng)有though, although時，后面的從句不能有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?nèi)栽诘乩锔苫睢?/p>

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.傷口雖愈合，但傷疤留下了。（諺語）

典型例題

1）___she is young, she knows quite a lot.A.When B.HoweverC.AlthoughD.Unless

答案：C。意為雖然她很年輕，卻知道許多。

2)as, though 引導(dǎo)的倒裝句

as / though引導(dǎo)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后。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+后綴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(dǎo)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(xiàn)在說什么也沒用了。(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.囚犯們只能給什么吃什么。三：主句與從句時態(tài)一致的問題。

在時間狀語從句和條件狀語從句中，主句和從句之間的時態(tài)一致問題一般分下列兩種情況：

1.若主句是祈使句，或主句中有情態(tài)動詞，或主句中謂語動詞是一般將來時，那么從句用一般現(xiàn)在時表示一般將來時。例如：

Be careful when you cross the road.過馬路時要小心。

Put up your hand if you have any questions to ask.如果你們有問題要問的話，請舉手。The traffic must stop when the lights are red.紅燈亮?xí)r，車輛必須停下。

2.若主從句謂語動詞都是陳述過去，那么主從句都可以用一般過去時。例如：She could sing when she was four years old.她四歲的時候就會唱歌。

第五篇：英語狀語從句

（三）狀語從句

（一）時間狀語從句

例題 I didn’t manage to do it _____ you had explained how.A.unlessB.untilC.whenD.since 分析 時間狀語從句在復(fù)合句中作狀語，表示主句動作發(fā)生的時間。引導(dǎo)這種從句的詞有after, before, as, when, while , till , until, since, once;連接副詞immediately 等；起連接作用的短語as soon as, by the 不能用形容詞such.例如：

● Soon there were so many deer that they ate up all the wild roses.4.so+ adj.(adv.)+that+從句●The boy is so old that he can go to school.5.so + adj.+ a(an)+單數(shù)名詞

●He is so good a student that we all like him.time, hardly…when, no sooner…than等。例如： ● I was writing a letter when he came in.● She did not go to bet until she(had)finished her homework.● It is nearly six years since we began to learn English.● Once you begin, you must go on.● By the time I arrived at the station, the train had left.時間狀語從句中謂語動詞的時態(tài)用法，應(yīng)注意下面兩點： 1． 要用一般現(xiàn)在時替代一般將來時，例如： ● I’ll let him know when he comes.2.要用一般過去時替代過去將來時，例如： ●He said he would wait here until I came back.例題的意思是：“直到你說明怎么辦之后，我才設(shè)法把這件事做好。”根據(jù)題意，須由until 引導(dǎo)此例的時間狀語從句，所以正確答案應(yīng)為B。

（二）地點狀語從句

例題 When you read the book , you’d better make a mark _____ you have any questions.A.at whichB.at whereC.the place whereD.where

分析 地點狀語從句在復(fù)合句中作狀語，表示主句的動作發(fā)生的處所或方向，這種從句通常用連接副詞where，wherever(無論在哪里，無論到哪里)引導(dǎo)。例如： ● Where there is oppression, there is struggle.例題的意思是：“你看書時，最好在有問題的地方做一個記號。”此復(fù)合句中的從句是個地點狀語從句，須用連接副詞where 引導(dǎo)，所以正確答案應(yīng)為D。

（三）結(jié)果（程度）狀語從句

例題 She told us _____story that we all forgot about the time.A.such an interestingB.such interesting aC.so an interestingD.a so interesting

分析 結(jié)果狀語從句在復(fù)合句中作狀語，表示主句的動作所引起的結(jié)果。這種從句由such…that, so…that, so that等引導(dǎo)。其用法舉例如下： 1． Such +a(an)+(adj.)+單數(shù)可數(shù)名詞+ that+從句

● He left in such a hurry that he forgot to lock the door.2.such+(adj.)+復(fù)數(shù)可數(shù)名詞+從句

●He had such long arms that he could almost touch the ceiling.3.such+(adj.)+不可數(shù)名詞+that+從句

●He made such rapid progress that he did very well in the mid-term exam.在“such+ adj.+ n.+that+ clause”這個結(jié)構(gòu)中，其中名詞由many, much, few, little 修飾時，須用副詞so,例題中的結(jié)果狀語從句由“such+ an + adj.+單數(shù)可數(shù)名詞+that”引導(dǎo)。屬于第一種情況，所以正確答案應(yīng)為A。

（四）目的狀語從句

例題 I hurried____ I wouldn’t be late for class.A.sinceB.so thatC.as ifD.unless 分析 目的狀語從句在復(fù)合句中作狀語，表示主句的動作發(fā)生的目的。這種從句用連詞so that, in order that 等引導(dǎo)。目的狀語從句的謂語動詞中常有情態(tài)動詞may/might, can/ could, will/ would 和should.例如：

● He is working hard so that he may pass his examination.例題中有一個目的狀語從句，所以正確答案應(yīng)為D。

（五）條件狀語從句

例題_____he comes, we won’t be able to go.A.WithoutB.UnlessC.ExceptD.Even 分析 條件狀語從句在復(fù)合句中作狀語，表示主句的動作發(fā)生的條件、假定等。條件狀語從句通常由連詞if, unless和起連接作用的短語so/ as long as(只要)，so far as(就…)，suppose(that)(假定)等引導(dǎo)。例如：

● If it rains tomorrow, we’ll stay at home.● He will not come unless he is invited.● Suppose he is absent, what shall we do?

● As long as we don’t lose heart , we’ll find a way to overcome the difficulty.例題的選項中只有unless 可以引導(dǎo)一個條件狀語從句，所以正確答案應(yīng)為B。

（六）讓步狀語從句

例題 _____, he doesn’t study well.A.As he is cleverB.He is as cleverC.Clever as he isD.As clever he is

分析 讓步狀語從句在復(fù)合句中作狀語，表示某種不利的情況或障礙，但這些因素并不能阻止主句的動作的發(fā)生。這種從句通常用連詞although, though, as, however等；連接代詞whatever, whoever等；起連接作用的短語even if though, no matter how what who 等引導(dǎo)。例如： ● Although/ Though the task was difficult, they managed to complete it in time.● Young as he is, he knows a lot.用as 引導(dǎo)讓步狀語從句時，常用倒裝語序，如上面例句所示。● Nobody believed him no matter what / whatever he said.● He will never succeed.however/no matter how hard he tries.● Even if/ though an icy wind blew from the north, we always slept with our windows open.例題中有一個as 引導(dǎo)的讓步狀語從句，故從句中的表語clever 須放到as 前面去，所以正確答案應(yīng)為C。
