Making Light of Sleep
Somewhere around puberty,something happens in the timing of the biological clock. The clock pushes forward,so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you its time for bed,your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.
But just like your alarm clock,your internal clock can be reset. In fact,it automatically resets itself every day. How? By using the light it gets through your eyes.
But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether its day or night.
1.make light of :轻视,不在乎。例如: We should not make light of their achievements.我们不应当低估他们的成就。
3. stay up:不睡觉,熬夜
5. get your bodys clock out of sync with the cycle of light and dark :打乱了你的生物钟与昼夜时间循环之间的平衡
