破句是把不完整的句子当作独立的句子来写时发生的错误。以下是常见的几个破句的例子：Students should be encouraged to take part-time job. Because it will benefit students and their family, even the society as a whole.点评：从属连词引起的破句。常见的从属连词有after,unless, even if, even though ,since , before , when (whenever),because, if, who(whoever),while, as (as if ), which(whichever), although , so that, where(wherever), until, that等。像because这样的从属连词开头的从句是不能单独存在的，它依赖于另一个句子方能使意义完整，也就是说单独的从句本身就是破句。修改后：Students should be encouraged to take part-time job because it will benefit students and their family, even the society as a whole.
