英语新闻听写 晚点上课有利健康

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 hormones¹ 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 fraction² 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.
