如何理解英语各类状语从句

NO.1 副词作状语

副词作状语
句子副词				连接副词				特别副词
actually, apparently, certainly, clearly, definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly				besides,meanwhile,then,therefore,thus,however,otherwise,so,yet				enough,too,very,much

(1)句子副词：

句子副词用于修饰句子(而不是修饰某个单个的词)，反映说话人的观点和看法。如 actually, apparently, certainly, clearly, definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly 等。

作用以及位置：

句子副词通常位于句首(或分句句首)。

Eg:

Obviously he can't tell the difference between them. 显然他无法区别两者的不同。

I arrived late but luckily the meeting had been delayed. 我迟到了，幸而会议推迟了。

但有些句子副词也可以出现句中。

eg： He smiled nastily. He evidently knew something I didn't. 他发出狞笑，他显然知道一些我所不知道的事。

有的句子也可用作其他种类的副词，不过这往往会导致位置和语义的变化：

Clearly he didn't say so. 显然他没有这样说。(句子副词)

He didn't say so clearly. 他说得没有那么清楚。(方式副词)

(2)起连词作用的副词

连接副词就是连接词，如besides，meanwhile，then, therefore, thus, However,Otherwise, so, yet 等。

作用以及位置：

常放在两个句子中间，前面为逗号，后面放连接词，从句之前。

注意：so 也可放在形容词之前做修饰，yet 可放句尾或从句之前。

(3) 特别副词

特别副词分别为enough, too, very , much 等

注意事项:

1.1 Enough 放在形容词和副词后，too 放在前面。

Eg: She’s old enough to do some work.

She’s too old to do any work.

1.2 Very 修饰形容词、副词；much 修饰动词(以及动词比较级）

Eg：Your work is very good.

This is much better.

NO.3 形容词及分词（短语）作状语

形容词作状语的情况

形容词除了常见的在句中作定语、表语和宾语补足语外，也可像副词一样在句中作状语。

1．原因

Overjoyed，he rushed out of the house．

Much interested，he agreed to give it a try．

Afraid of difficulties，they prefer to take the easy road．

2．时间

Ripe（When ripe），these apples are sweet．

3．伴随或方式

He spent 7days in the wind and snow，cold and hungry．

Helpless,we watched the house being destroyed before our eyes．

二、可用作伴随状语的几种方式

1．形容词

They all rushed up，eager to help．

She returned to work，unhappy．

2．现在分词

I don't like to sit here doing nothing．

He rushed out，even forgetting to take his overcoat．

3．过去分词

Accompanied by the professor，he spent several days doing experiments one after another．

4．介词短语

I said it in fun．

5．名词短语

Theory should go hand in hand with practice．

6．独立结构

He lay on his back，his hands crossed under his head．

The teacher came in，book in hand．

With the old man leading，they two started toward the mountain．

Now he could walk only with his brother supporting him．

一般情况下，由副词在句子中作状语，用与修饰动词；修饰形容词或者副词；或者修饰整个句子。但是对于形容词作状语这一现象，很多同学难以理解，实际上，形容词作状语的现象是不少见。该形容词通常用来说明主语的情况，常常可以单独或者引起一短语作状语；可以表示原因，也以表示动作的情况或者方方式，或者表原因。

1、Afraid of being caught，the thief hid himself under a bed.

因为害怕被抓，这个小偷藏在床下面。

2、Unable to answer the question，the students keep silent.

因为不能回答该问题，这些学生保存沉默。

表动作的情况或者方式
