第三篇：状语从句

Clauses of Condition, Concession and Contrast(条件、让步和对比从句)条件从句

由 if, unless, as(so)long as, provided / providing(that), suppose / supposing(that), in case等引导，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.让步从句

由 although, though, even though, even if, whether...or, while, as, wh-words + ever(= no matter + wh-words)等从属连词引导，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.使用上述让步从句的某些从属连词时注意以下几点：

a.although(though)不可与连词 but 连用；

b.as 引导的从句意义和 though 相似，但表示的语气较强，并须将强调的词放在句首（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 引导的从句中，however / no matter how 后须紧跟形容词或副词，如：

However / No matter how hard I tried, I couldn't remember all the questions.对比从句

表示两个人或两件事之间的对比，常用 while 或 whereas 引导，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、结果和目的从句)原因从句

主要由下列从属连词引导：

1． Because, as, since。其中 because 语气最强，表示直接、主要原因，通常引导的从句放在句尾，特别是回答 why 提出的问题只能用 because;as 和 since 表示明显的、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。这些连词与 as, since 意思相近，通常用于书面语，并且它们兼有其它意义。now that 有“时间”含义，表示”既然”，说明一种新

情况；seeing(that)和 considering(that)有“条件”含义；in that 有”某一方面”含义，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）.结果从句

常用 so that, so...that, such...that, that 等连词引导，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.目的从句

常用 so that, in order(that), lest, for fear that 等连词引导，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 既可引导结果从句也可引导目的从句，但结果从句表示事实，通常不含情态动词；目的从句表示希望或想要实现的事实，通常含有情态动词，如：

He got up early so that he caught the train.（结果）

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

Lest 和 for fear(that)含有否定意义，并且从句中动词须用 “动词原形”或 ”should + V.” 的虚拟语气，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(方式和比较从句)方式从句

主要由 just as, as, as if, as though 等连词引导，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 引导的从句通常用虚拟语气，但如果主句谓语是感官动词，并且所述情况实现可能性大，也可用陈述语气，如：

It looks as if the coming autumn harvest will be even better than the last one.比较从句

主要由 as...as, not so(as)...as, than 等连词引导，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(比例从句和其它从句)比例从句

由关联词 the...the...连接形容词或副词比较级构成，如：

The more she thought about it, the more she liked it.其它从句

如 as...so 和 what...that 引导的类比从句；so(as)far as 引导的范围从句；except that 引导的例外从句；rather / sooner than 和 would / had rather than 引导的择比从句等，如：

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

What blood vessel is to a man's body, that railway is to transportation.（铁路对于运输，好比血管对于人的身体。）

As(So)far as I know, he is an honest man.（据我所知，他是一个诚实的人。）

I would do it with pleasure, except that I am too busy.（要不是我太忙了，我会很高兴去做的。）

Rather than get money in such a dishonest way, he would beg in the streets.（他宁可沿街乞讨，也不愿意用欺骗手段骗取钱。）

He would rather have the small one than the large one.（他宁可要那个小的，而不愿要那个大的。）

第四篇：202_高考英语 30分钟专题突破精讲 连词和状语从句

202_高考英语30分钟专题突破精讲：连词和状语从句

考点一 连词

在句中连接单词、短语、从句或者句子的词为连词。根据句子的结构特点，连词通常分为并列连词和从属连词。

1．并列连词按照在句中的作用可分为：表并列关系的连词（and，as well as，both...and...，not only...but also...，neither...nor...等）、表转折关系的连词（but，yet，however，while，nevertheless等）、表选择关系的连词（or，either...or...，otherwise等）、表因果关系的连词（for，so，therefore等）。

—Why do you like staying in Guiyang?

—Because the weather there is neither too hot nor too cold.2．引导名词性从句或状语从句的主要有以下从属连词：

that，whether，if，as，when，while，till，until，since，after，before，because，though，although，so...that，where等。

I arrived after he left.考点二 时间状语从句

1．when，while，as都可译为“当„„的时候”，但侧重点有所不同。

当主句动作是瞬时的，从句动作是延续的时，三者都可以用。

as强调主、从句动作同时或几乎同时发生。

while从句的谓语必须是延续的，不能是非延续性动词。She sang as we walked.I listened carefully while she was singing，and we felt happy when we got home.我们一边走她一边唱，她唱的时候我认真听。到家的时候我们感觉很高兴。

2．until 和not...until

until 要与延续性动词连用； not...until 要与非延续性动词连用。

He didn't go to bed until his father came back.3．特殊的时间状语从句的引导词

1）the moment，the minute，the instant，the second；no sooner...than...；hardly/scarcely...when...等以及表示瞬间的directly，immediately，表示“一„„就„„”，相当于as soon as。no sooner...than...，hardly/scarcely...when...结构中no sooner和hardly/scarcely引导的句子中谓语动词通常用过去完成时，而than和when引导的句子中谓语动词通常要用一般过去时，此外，no sooner和hardly/scarcely位于句首时，句子应用部分倒装语序。Tell him the news the minute you meet Tom.Hardly had I got home when it began to rain.2）next time，the first time，last time，every time，the spring（summer，autumn，winter）等，这类短语名词直接用作连词引导时间状语从句。

Every time I see him he wears a pleasant smile.4．by the time 也可以引导时间状语从句，意为“到„„时为止”，主句一般用完成时态。

By the time he was fourteen，Einstein had learned advanced mathematics all by himself.（从句为一般过去时，主句要用过去完成时）

5．几组固定形式

1）It will be＋一段时间＋before...多久之后才„„

2）It is＋一段时间＋since...自从„„以来已有多长时间了。

3）be about to do...when...；be doing...when...；on the point of doing...when...It will be two days before he returns.It is three years since I came here.I was doing my homework when my cousin came.考点三 结果状语从句

其常用句型：

so＋形容词/副词＋that从句

so＋形容词＋a/an＋单数可数名词＋that从句

so＋many/much/little（少）/few＋名词＋that从句

such ＋a/an＋形容词＋单数可数名词＋that从句

such ＋形容词＋复数可数名词/不可数名词＋that从句

He is so young that he can not go to school.It is such fine weather that we all want to go out for a walk.考点四 because，since，as和now that

1．because为常用词，且说明的是直接原因，并可回答why引导的问句。

2．as，since和now that语气较弱，常用来表示一些显而易见或对方知道的原因。since译为“既然，鉴于”时不可用as替换。I didn't come to school yesterday because I was ill.—Why are you late today?

—Because I didn't catch the bus.As it's raining，you'd better take a taxi.Since everybody is here，let's begin.考点五 让步状语从句

引导让步状语从句的连词有：though，although，even if/ though，however，no matter how，no matter what，no matter who等。

1．though，although引导让步状语从句时都不能和but连用，但可以同yet（still）连用。

Although he is rich，yet he is not happy.2．as/though引导的让步从句时，从句要采用倒装语序。

Child as /though he was，he knew what was the right thing to do.Try hard as he will，he never seems to do the work well.Young as/though he is，he is expert in this field.3．whether...or not意为“无论（是否）”。

Whether you believe it or not，it is true.4．however＋形容词/副词＝ no matter how＋形容词/ 副词„„，意为“无论多么„„”。

No matter how cold it is，he still works outdoors.5．wh­ever等一系列连词既可引导让步状语从句相当于no matter wh­，也可引导名词性从句。而no matter wh­只能引导让步状语从句，不能引导名词性从句。

No matter what happened，he would not mind.＝Whatever happened，he would not mind.考点六 条件状语从句

条件状语从句通常分为两大类：真实条件句和虚拟条件句。引导条件状语从句的连词有：if，unless/ if...not，as long as/ so long as，as far as/so far as，provided/providing（that），on condition that等。

1．条件状语从句中如果主句是将来时，条件状语从句用一般现在时。如果条件状语从句中出现过去式，则为虚拟条件句，那么主句要用相应的虚拟语气形式。

If he is not at home，I will come again.If he had listened carefully，he would have done it better.2．unless 相当于if...not，在虚拟条件句中可用if...not，但不能用unless。You will fail unless you study hard.If she were not too silly，she would understand it.考点七 目的状语从句

目的状语从句常用的连词（短语）有so that（以便），in order that（以便），lest，in case，for fear that...等。

1．so that / in order that 引导的目的状语从句中常用情态动词can，could等。in order that 引导的目的状语从句可以放在主句之前或之后，而so that引导的目的状语从句只能放在主句之后。

He spoke loudly so that / in order that all the people could hear him clearly.2．lest，in case，for fear that所引导的状语从句中，谓语动词可以用虚拟语气，形式为“should＋动词原形”，也可不用虚拟语气。

He wrote the name down for fear that he should forget it.You may leave the key at home in case one of us should think of/thinks of coming back.高考英语30分钟专题突破（15）：
