Most of us sleep fewer than nine hours every night, because we have much homework to do.Some homework is given by our teachers, and some by our parents.We have to stay up late, and get up early in the morning to get to school on time by bus or bike.It can be a long way from home to school.
我们大部分人每晚睡眠不足9小时，因为我们要做许多作业。有些作业是老师留的，有些是家长留的。我们不得不熬的很晚，而早晨又得早起，为了乘公共汽车或骑车按时赶到学校。从家到学校可能是很远的路。
