問題詳情：

After a late night doing tons of homework, you are trying hard to keep your eyes open in class. “  16   ” You are probably thinking. “This weekend I’ll make up for all the sleep I have lost.”

   Most people think like you, that if you stay in bed longer on Saturdays and Sundays, you will catch up hour-by-hour on your missed sleep during the week.

   However, this is wrong.  17  In fact, scientists have just found that sleeping-in during the weekend will not do you any good, but rather make you feel more tired on Monday morning, reported The Telegraph.

       18   It tells us when to wake up in the morning and when to feel sleepy at night. But the time on our body clock can be changed if we start taking on different sleeping habits.   19  

   If we decide to get up only    20  minutes or half an hour late, it won’t matter. This is because our body clock can accommodate(適應) a delay of up to an hour, which means that a short lie-in at weekends is unlikely to have any big effect. 20 This means on Monday morning we sometimes struggle to get out of bed.

   So, what should we do to balance out all the rest we’ve missed? Scientists say that simply getting eight hours of sleep would do the trick, not any longer,. That’s because our brain rests more efficiently when it’s tired.

A. Sleeping is nothing like paying back money.

B. Sleep is important for everyone.

C. This is why staying in bed for longer than usual might confuse our body clock.

D. But delays of up to two hours or more can throw our body out of order.

E. I need more sleep!

F. However, if we sleep longer, our sleep becomes less efficient.

G. Our body keeps a clock inside.
