高中英语状语从句讲解汇总

在句子中起状语作用的从句叫状语从句。状语从句可位于主句之前，也可位于主句之后。状语从句可以分为时间状语从句、地点状语从句、条件状语从句、让步状语从句、原因状语从句、目的状语从句、结果状语从句、方式状语从句、比较状语从句等。

一，方式状语从句

引导状语从句的连词和词组有：as,as if,as though等。

留意：①as if/though从句经常用虚拟语气，表示与事实相反。

She always talked to me as if she were mysister.

②有时从句也可用称述语气，表示所说情况是事实或实现的可能性较大。

He treats me as if I am a stranger.

③从句有时可以省略某些成分。

The wounded soldier cried as(he were)in great pain.

④as if/though也可以引导表语从句。.When a pencil is partly in a glass of water, it looks as if

it______.[N95]

A.breaks

B.was broken

C.were broken

D.had been broken

【简析】当as if引导虚拟语气的句子时，假如主句与从句的谓语动词同时发生，从句用一般过往时；假如从句谓语动词发生在主句谓语动词之前，从句用过往完成时。该题主句与从句的谓语动词同时发生，表示与现在事实相反，故答案为C。

二，比较状语从句

引导比较状语从句的连词和词组有：than, as…as…,not so…as…, the+比较级…, the+比较级等A hare can walk faster than a tortoise runs.

She is as tall as her mother (is).

留意：有时在than从句中，若有省略，所使用的代词的格不同，含义不同。

She respects him more than I.她比我更尊敬他。

She respects him more than me.她尊敬他甚于尊敬我。

☆比较while, when, as

1）as, when （正当）引导短暂性动作的动词。例如：

Just as / Just when / When I stopped my car, a man came up to me. 我一刹车，有一个人向我走来。

下。

2）从句表示"随时间推移"连词能用as，不用when 或while。例如：

As the day went on, the weather got worse.日子一天天过去，天气越变越坏。

A, 形容词和限定动词连用时的比较

It’s darker today than it was yesterday．

今天比昨天天色昏暗。

He doesn’t pay as much tax as we do／as us．

他没我们交的税款多。

He spends more than he earns．

他花的比挣的多。

注意：that＋形容词是一种口语形式，表示“那么……”：

—Will it cost￡100？

—No，it won’t cost as much as（all）that．It won’t be（all）that expensive．／It won’t be as expensive as that．

—要花100英镑吗？

—不，花不了那么多。没那么贵。

that＋形容词结构有时用于口语中表示very（很）的意思。

B, 副词和限定动词连用时的比较

He didn’t play as well as we expected／as well as you（did）．

他打得不如我们预料的好／你打得好。

He sings more loudly than anyone I’ve ever heard／than anyone else （does）．

他唱得比我听到的任何人唱得都响／比任何人都声音响。

You work harder than he does／than him／than I did at your age．

你比他干得卖劲／我在你这个年龄时干得卖劲。

C 形容词和不定式或动名词连用时的比较：

通常两者都可使用，但动词不定式常常用于特定的动作，动名词则用于一般情况

It’s sometimes as cheap to buy a new one as（it is）（to）repair the old one．

Buying a new one is sometimes as cheap as repairing the old one．

有时买一个新的跟修理旧的一样便宜。

He thinks it（is）safer to drive himself than（to）let me drive．

He thinks that driving himself is safer than letting me drive．

他认为自己开车要比让我开车更安全些。

D,上面C所述的这种比较句式中，如as／than前面用的是动词原形，则常在as／than后面用动词原形而不用动名词。与此相同，如as／than前面用的是动名词，则在其后面一般也使用动名词，而不用动词原形，见前面的例子。位于as／than之前的限定动词＋this／that／which后面多跟动名词，虽也可跟动词不定式：

I’ll deliver it by hand；this will be cheaper than posting it．

我自己送过去，这样比邮寄要便宜。

He cleaned his shoes，which was better than doing nothing．

他把自己的鞋擦了，这总比无事可做好。

E,动词原形与would rather／sooner连用Most people would rather work than starve．
