（二）副词的用法和位置

1 修饰形容词用作状语，一般放在形容词的前面。

如：The passengers are very worried about the weather.

The little girl was too disappointed to say a word because her father couldn t come back

home on time.

2 修饰动词用作状语，一般放在动词的后面。

如： It is snowing heavily.

The conductor tells the passengers to stay inside until the snow stops.

3 修饰整个句子用作状语，放在句首。

如：Luckily, the conductor told them that train would start soon.

4 修饰副词用作状语，一般放在被修饰的副词的前面。

如：The conductor is very tired after one-day work because she has worked too hard.

Things to remember:

1) 表示频度来修饰动词用作状语的副词，要放在连系动词、情态动词或助动词的后面，行为动词的前面。

如：The passengers often go back home to spend the holiday with their family. But they have never met such a storm in the last 50 years.

2）副词的词形

副词的词形分单纯性和派生性。单纯性副词如：today, rather, there, however等等。派生性副词由形容词加-ly变过来的。它们的转换方式有：

（1）一般由形容词加-ly构成，如：bad---badly, clear---clearly

（2）当形容词以-y结尾时，将y改为i再加-ly,如：easy---easily, lucky---luckily

但是有些词虽然是以-ly结尾的，却不是副词，而是形容词，如：friendly, lovely

（3）有些形容词和副词同形，如：hard, early, enough等，既可以作形容词，也可以作副词，如：It s hard to say what the weather will be like tomorrow. (形容词)

The conductor works hard to satisfy the passengers.

3) enough 作为形容词，修饰名词，要放在名词的前面，如：The conductor gave the passengers enough water to drink.

enough 修饰形容词和副词用作状语，都要放在形容词和副词的后面。

如：The railway is not safe enough for the train to run on yet.

Trains must run slowly enough in order for the passengers to go back home safely in freezing weather.

4）做题时要注意副词与形容词或动词的正确搭配。

如：The transportation problem is quite ________.

The transportation problem can t be _________ easily.

在前一句中，通过副词 quite ，我们可以判断此句需要一个形容词；而在后一句中，通过副词 easily ，我们可以判断此句需要一个动词， 因为 easily 是一个修饰做某事难易的副词。
