分号分号链接的是两个完整的句子,用分号代替句号则这两个句子的关系非常密切。即使句子中间含有连接副词(如however, otherwise, therefore和nevertheless等),前后两句依然需要用分号连接。比如You have to return all the books within two weeks; otherwise, you can’t borrow any more 当句子中已含有一个或多个逗号时,分号还可以被当作一种“超级逗号”来使用,这样句子的逻辑关系更加明确。比如Sun com Corporation has subsidiaries in three cities: New York, the biggest city in the US; Washington, the capital of the US; and San Francisco in C注意,当两个句子由连词连接时一般用逗号不用分号。
