Studies have shown there are health benefits for starting school at a later in the morning.

研究表明，早上晚点开始上课对健康有好处。

According to mnn.com, "Thanks to hormones and bodily changes, many teens have a harder time falling asleep at night and therefore a harder time dragging themselves out of bed in the morning.

据医学新闻网报道，“由于荷尔蒙和身体的变化，许多青少年晚上入睡困难，因此早上很难从床上爬起来。

When they do get up , it's often after getting only a fraction of the nine plus hours of sleep they need to stay healthy."

即使起床，他们也只是睡了健康所需的睡眠的一部分，而他们需要睡九个小时以上才能保持健康。”

Changing school staring times to 8:30 or later will help them more easily reach nine hours of sleep.

将学校开始上课的时间改到8:30或者之后，他们睡够9个小时就容易一些。

Unfortunately, many school officials are still debate as whether or not this time change would cost or save them money.

不幸的是，许多学校的官员仍在争论，这样的改变会为他们省钱还是会造成损失。
