It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong. Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school?

During adolescence, the body goes through many changes and these include a shift in sleep patterns. Researchers from MIT have been tracking the body’s need for sleep in teenagers. They found that though adolescents need as much as 9.5 hours of sleep a day, they get to bed later and later with each passing year. In fact, the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20! So by the time a 10?year?old who sleeps at 8 pm grows to be 17 or 18, his body naturally wants to stay up till 10：30 pm or 11 pm.

According to researchers, this is because of a hormone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland — a tiny structure deep inside the brain. Melatonin regulates the body’s natural day?night rhythms. It causes a person to become sleepy by lowering his body’s core temperature. In teens, melatonin is secreted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Likewise, the effect of melatonin continues until much later in the morning, making it hard for them to wake up early.

A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep, important body functions and brain activities happen. So how can teenagers get their sleep enough? The American Academy of Pediatrics (AAP) recommends that middle and high schools should start later — not before 8：30 am. This should give teens some more time to sleep at night.

1.From Paragraph 2, we can learn that if you sleep late, the next day you should ________.

A. stay sharp B. skip breakfast

C. get up late D. stay up late

2.What does the underlined word “this” in Paragraph 3 refer to?

A. The students want to stay up.

B. The shifts of the sleep cycle.

C. The pineal gland secretes melatonin.

D. The adolescents sleep late.

3.The teens go to sleep later than before because ________.

A. melatonin is secreted much later

B. melatonin regulates the sleep time

C. they sleep a lot in the daytime

D. they need to finish their homework

4.According to AAP’s recommendation, middle and high schools should ________.

A. let teens sleep in the day B. let the students be active

C. delay the start time D. start later at 8 am

In the dull twilight of the winter afternoon,Scarlett came to the end of the long road which had begun the night Atlanta fell.She had set her feet upon that road as a spoiled,selfish and untried girl,full of youth,warm of emotion, easily confused by life.Now,at the end of the road,there was nothing left of that girl.Hunger and hard labor,fear and constant pressure,the terrors of war and the terrors of Reconstruction had taken away all warmth and youth and softness.Around the core of her being,a shell of hardness had formed and,little by little,layer by layer,the shell had thickened during the endless months.

But until this very day,two hopes had been left to support her.She had hoped that the war being over,life would gradually return to its old face.She had hoped that Ashley's return would bring back some meaning into life.Now both hopes were gone.She realized that for her,for the whale South,the war would never end.The bitterest fighting, the most violent and cruel revenges,were just beginning.And Ashley was imprisoned forever by words which were stronger than any jail.

Peace had failed her and Ashley had failed her,both in the same day,and it was as if the last crevice（裂口）in the shell had been closed,the final layer hardened.She had become what Grandma Fontaine had counseled against,a woman who had seen the worst and so had nothing else to fear.Not life nor Mother nor loss of love nor public opinion.Only hunger and her nightmare dream of hunger could make her afraid.

A curious sense of lightness,of freedom,went through her now that she had finally hardened her heart against everything that tied her to the old days and the old Scarlett.She had made her decision and,thank God,she wasn't afraid.She had nothing to lose and her mind was made up.

3.What does the underlined sentence "...and it was as if the last crevice in the shell had been closed,the final layer hardened" suggest?

A. Scarlett would shut herself off from others.

B. Scarlett would refuse to face the reality.

C. Scarlett.would be trapped in a state of desperation.

D. Scarlett would grow mentally tougher and more determined.
