连  词

连词是一种虚词，不能独立担任句子成分，只起连接词与词、短语与短语以及句子与句子的作用。连词一般分为并列连词(连接平行的词、词组或分句)和从属连词(用来引起分句)。除了连词外，许多连接代词、连接副词、关系代词和关系副词都可以用来引起一个从句。还有一些副词，如anyway，therefore，also，still等也有类似的作用。另外，有些词组，如: on the other hand，for that reason等也可以帮助前后文更加连贯。考生在准备连词时应注意以下几个问题。

1. 连接两个分句，一个连词就够了。容易出错的典型例子是：
Although he was tired, but he went to work.
Because she liked him, so she went out with him.

在上面所提到的两个例子中，我们可以选用although或but，because或so，不能同时使用两个连词。但是连接三个分句时，可以用两个连词。如：
Although he was tired, he went to work, but he didn't stay there long.
类似的错误还有把that和where，how或whether连在一起用。如：
I asked him that how he was working.来源：www.examda.com
l wondered that where he lived.

2. 关系代词who，whom和which的一个特殊用法是可以连接分句。所以它们既是代词，又是连词。容易出错的典型例子是：
He never listens to the advice which I give it to her.
在该句中it是多余的，which连接两个分句，同时又代替it而成为第二个分句的宾语。

3. That经常用来代替which和who，但是不常用that来代替where和when。容易出错的典型例子是:
The house that she lives is very small.
正确的句子应该是：
The house where she lives is very small.
The house that she lives in is very small.

4. 连词不能单独和一个分句连用。连接词要连接两个分句，而这两个分句一般要写成一句话，即不能写成中间用句号隔开的两个独立的句子。容易出错的典型例子是：
When I came back home. It was late.
