并列句中的标点用法
1) 逗号+并列连词
The clock was old , yet it was in excellent condition.
There was little formality in class , but Mr Stone never had to discipline us.
注：ⅰ）在较短的句子中，逗号可以省略。例如：
Many are called but few are chosen.
然而有时单个词后面也需用标点，否则表示不同的句意。例如：
Again , we lost our way. （而且我们迷路了。）
Again we lost our way. （我们又一次迷路。）
ⅱ）有两个以上分句时，前几个分句之间用逗号，最后两个分句之间用逗号加连词。例如：
The night wind died down , night closed in , the moon came out , and lights came on in the scattered houses.
2) 分号
They live on the first floor ; we live on the second. (对比)
Everyone was late ; the snow had caused a traffic jam. (补充说明)
3) 分号+连接性副词+逗号
We didn’t like the choice ; however , we had to accept it.
We didn’t know what to do ; therefore , we did nothing.
适用于这种情况的连接性副词还有：consequently，furthermore，moreover，nevertheless等。
注：ⅰ）连接性副词位于句末时，前面一般用逗号，后面用句号。例如：
The new seats in the auditorium are more comfortable; the acoustics are worse , however.
ⅱ) 连接性副词也放在句首，后面用逗号。例如：
I hadn’t read the test very carefully. Therefore , I was surprised that I had done so well.
I hadn’t read the test very carefully ; therefore , I was surprised that I had done so well.
ⅲ) then 和thus后面不用逗号。例如：
The ice cracked and split ; then that boy sank into the bone-chilling water.
