No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).
There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.
Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend(倾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.According to the passage, some people are unable to think clearly because ___________ .

Amelia Earhart's (1897-1937) childhood was not the typical girl’s. She liked nothing better than to explore the banks of the Missouri River, where she climbed trees and hunted rats with her rifle (步枪). She also built her own roller coaster(过山车 ).
The exciting life of the American aviation (航空)pioneer is dramatized in the movie Amelia, which is due to come out on October 23.
After Earhart paid a pilot $1 to take her up for a short fly in his plane, aviation became her love and career.
As she later explained, “Never do things others can do and will do, if there are things others cannot do or will not do.”
Earhart found herself a flying teacher and started to learn to fly. She took all sorts of jobs to pay for the lessons and to buy a second-hand plane on her 24th birthday.
In 1932, Earhart flew solo across the Atlantic. She became the first woman to make the solo crossing. She also made a flying suit for women and went on to design other clothes for women who led active lives. “Now and then women should do for themselves what men have already done —— occasionally what men have not done ——thereby establishing themselves as persons, and perhaps encouraging other women toward greater independence of thought and action.” she said.
When she was nearly 40, Earhart was ready for a final challenge—to be the first woman to fly around the world. However, in mid-flight, she and her navigator (导航员) disappeared in bad weather.
Earhart will be forever remembered as a brave pioneer for both aviation and for women.

Aren’t they all our children?
There are few things in this life more difficult to experience than the loss of one’s child. Jim Wallis, in WHO SPEAKS FOR GOD, tells a story that happened during the war in Sarajevo. A reporter who was covering the violence in the middle of the city saw a little girl shot by a gunman.
The reporter rushed to the aid of a man who was now holding the child. He helped them both into his car and sped off to a hospital.
“Hurry, my friend,” the man urged, “my child is still alive.” A moment or two later he pleaded, “Hurry, my friend, my child is still breathing.” A little later he said, “Hurry, my friend, my child is still warm.”
When they got to the hospital, the young girl was gone. “This is a terrible task for me,” the distraught man said to the reporter. “I must go and tell her father that his child is dead.”
He looked at the man in surprise and said, “I thought she was your child.”
The man replied, “No, but aren't they all our children?”
I think that is one of the great questions of our age that deserves an answer.
Aren’t they all our children? Those on our side of the border as well as those on the other side? Those of our nation no more or less than those of another?
Aren’t they all our children? The well-educated and the under-educated? The well-fed and the under-fed? Those who are secure and those who are at risk?
Aren’t they all our children? if we say yes, can we ever again pit them against each other? “If we have no peace,” said Mother Teresa, “it is because we have forgotten that we belong to each other.”
There may be no greater question for our generation. And how we answer that question will determine the shape of our world for years to come.

THE situation seemed hopeless．
From the day he started at my junior-high，Willard P.Franklin lived in his own world，shutting out his classmates and me, his teacher．My attempts at establishing a friendly relationship with him were met with complete indifference(冷淡)．Even a “Good Morning Willard” received only a very low grunt(咕哝)．I could see that his classmates got on no better Willard was completely a loner who seemed to have no desire or need to break his barrier(障碍)of silence．
Shortly after the Thanksgiving holiday，we received word of the annual Christmas collection of money for the less fortunate people in our school district．
“Christmas is a season of giving,” I told my students．“There are a few students in the school who might not have a happy holiday season．By contributing to our Christmas collection，you will help buy food，clothing and toys for these needy people．We start the collection tomorrow．”
When I called for the contributions the next day，I discovered that almost everyone had forgotten，except for Willard P. Franklin．The boy dug deep into his pants pockets as he walked up to my desk．Carefully, he dropped two quarters into the small container.
“I don’t need any milk for lunch,” he said very quietly. For a moment，just a moment, he smiled．Then he turned and walked back to his desk．
That night，after school．I took our meager contributions to the school principal(校长)．I couldn’t help sharing the incident that had taken place．
“I may be wrong，but I believe Willard might be getting ready to become a part of the world around him，”I told the principal．
“Yes, I believe it sounds hopeful．”he nodded．“And I think we might do well to have him share a bit of his world with us．I just received a list of the poor families in our school who most need help through the Christmas collection．Here, take a look at it．”

RIDING in school buses in the early morning，then sitting in poorly lit classrooms，are the main reasons students have trouble getting to sleep at night，according to new research．
Teenagers，like everyone else，need bright light in the morning to allow their circadian rhythms(生理节奏)to get into step with nature's cycles of day and night．
If they don't get blue 1ight in the morning，they get to sleep an average of six minutes later at night，until their bodies are completely out of sync(同步) with the school day，researchers from Rensselaer Polytechnic Institute in New York said last month．
The finding was made by fitting goggles(护目镜)that block blue light from the sun to a group of students．The researchers discovered that their circadian rhythms were greatly affected．
Parents and teachers have been complaining in recent years that teens stay up too late at night，then fall asleep in class the next morning and do poorly in school．The new findings provide a possible explanation for the problem．
At the root of the research is the circadian rhythm, the body's natural sleep and waking cycle．Even though the Earth makes a full rotation(旋转)in 24 hours，the body's circadian cycle is about 24 hours and six minutes 1ong．The cycle is mediated(调节)by a chemical called melatonin(褪黑激素)．The body starts to produce it about two hours before it is time to sleep and, in the absence of blue 1ight，the body produces about six minutes later each day.
In the study, the researchers studied 11 students at Smith Middle School in New York, which was designed so that a lot of sunlight reaches classrooms．
On a Friday night，the researchers measured what time the 11 students’ bodies began releasing melatonin．On Monday morning，the students were sent to school with orange goggles that blocked most blue light from their eyes to mimic(模拟) the conditions found in many---if not most--schools．
By the end of the week，the students were releasing melatonin 30 minutes 1ater in the evening---an average of six minutes a day--and going to sleep correspondingly(相应的) later．
“This is our first field study，”said lead author Mariana G．Figueiro．He said they would like to repeat it in larger studies and for longer periods of time。
If the findings are repeated，a variety of solutions are available．Ideally, new schools would be built to allow more natural sunlight into the classrooms．Students could also be exposed to more sunlight outside．
68. According to the findings related in this article, many teenagers stay up late because_______
A. they lack melatonin in their bodies
B. they have to get up so early to catch the school bus
C. their circadian rhythms are in disorder
D. they do not get enough blue light in the morning
69. According to the findings, a student who normally slept at 10:00 pm, but who spent 10 days in a poorly lit classroom, would probably be falling asleep at___________after the period.
A. 12:00pm B. 11:30pm C. 11:00pm D. 10:00pm
70. What does the article tell us?
A. Unlike adults, teenagers tend to feel sleepy during daytime.
B. The sunlight is the only thing that can affect our circadian rhythms.
C. If the findings prove correct, solutions could be found to teen sleeping problems.
D. Most schools have small windows and the classrooms are poorly lit.
71. The main point of the article is to___________
A. warn teenagers not to stay up late or sleep in class
B. report on some new findings related to teenagers' sleeping problems
C. give suggestions on how to build schools
D. advertise goggles which can protect the eyes from the sun
