no matter how = however

注意：no matter 不能引导主语从句和宾语从句。（错）No matter what you say is of no use now. （对）Whatever you say is of no use now.

（错）Prisoners have to eat no matter what they’re given,

（对）Prisoners have to eat whatever they’re given.

8．比较状语从句

常用引导词：as(同级比较), than(不同程度的比较)

特殊引导词：the more … the more … ; just as …， so…; A is to B what /as X is to Y; no … more than; not A so much as B She is as bad-tempered as her mother.

The more you exercise, the healthier you will be.

Food is to men what oil is to machine. no more than只不过(嫌少的意思) not more than不如。。。(前者不如后者)

9．方式状语从句

常用引导词：as, (just) as…so…, as if/though(\正如…\，\就像\ 特殊引导词：the way

When in Rome, do as the Roman do. She behaved as if she were the boss.

Sometimes we teach our children the way our parents have taught us. as if, as though

两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作\仿佛……似的\，\好像……似的\

They completely ignore these facts as if (as though) they never existed. He looks as if (as though) he had been hit by lighting.

状语从句的省略

状语从句同时具备下列两个条件:

① 主句和从句的主语一致，或从句主语为it；

②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。

When ( the museum is ) completed , the museum will be open to the public next year .

He’ll go to the seaside for his holiday if (it is ) possible. 另外，比较状语从句经常省略。 I’m taller than he (is tall ).

The higher the temperature (is), the greater the pressure (is ).

状语从句的\省略\现象常存在于以下五种状语从句中: ①由if, unless等引导的条件状语从句;

②由although, though, even if / though等引导的让步状语从句; ③由when, while, as, before, after, until / till等引导的时间状语从句; ④由as, as if等引导的方式状语从句; ⑤由as, than等引导的比较状语从句。下面针对这五种情形作归纳。

(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。

If (it is) possible, he will help you out of the difficulty. You must attend the meeting unless (it is) inconvenient to you

(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形: a.连词+形容词

As (he was) young, he learned how to ride a bike. Whenever (she is) free, she often goes shopping. Work hard when (you are) young, or you'll regret. b.连词+名词

While (he was) a young boy, he was always ready to help others. Although (he was) a farmer, now he is a famous director. c.连词+现在分词

As (she was) walking along the river bank, she was singing a pop song. Although (he is) doing his best in maths these days, he has still got no good marks.

d.连词+过去分词

He won't go there with us unless (he is) invited. The concert was a great success than (it was) expected. e.连词+不定式

He stood up as if (he were) to say something.

He wouldn't solve the problem even if (he were) to take charge. f. 连词+介词短语

She looked anxious as though (she was) in trouble.

He had mastered the English language before (he was) in the USA.

注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。

When the meeting was over, all the people went out of the meeting-room.
