作为并列标记的标点符号

标点符号作为并列标记，除逗号外还有分号（；）和冒号（：）。

一般说来，用分号连接并列分句，通常表示并列或对比。例如：
   It is one thing to be dignified and detached; it is quite another to be downright rude.

The country wants the new expressway; the city wants to renew its streets.

用冒号连接两个并列分句通常表示“引申”，即表示下文是对上文的说明和发挥。例如：

Sports at age are beneficial: they keep your pulses hopping.

His game was ragged: he went into sand traps four times and into the trees five.

某些连接副词如consequently, furthermore, hence, however, nevertheless, therefore等也可用作并列标记，在这些副词之前要用分号，而不能用逗号。例如：

His hair was white and stood up wildly on his head; nevertheless, I was struck by a singular neatness in his appearance.

It was raining hard; however, I insisted that we should start on the journey as had been scheduled.

I had arrived early as was my habit; I, therefore, felt privileged to take my leave without delay.
