Question

关于专四听写的一些问题 急.and 之前要加逗号吗,怎么有些地方加,有些地方不加 even a few years ag

Answer 1

I．逗号（,）

1)在并列句中,连词（and,but,or,for,so,nor,yet）的前面用逗号.

应当指出,如果两个或三个并列从句都很简短,意思又紧密相连,它们之间可以不用连词而只用逗号：

A memoir is history,it is based on evidence.

2)写日期时,如次序是月－日－年,在日和年之间加逗号.如次序是日－月－年,则不加逗号：

He was born on October 15,1983.

He was born on 15 October 1983.

注意：英文中是没有顿号的,基本上可以说在中文中用顿号的地方可以用逗号取代.
