Reducing the amount of sleep affects students’ performance at school. An American study asked schoolteachers to look at the effects of sleep restriction(限制） on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.
The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.
The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficult remembering old information.
The study did not find that sleep restriction caused hyperactivity(极度活跃) in the children.
Doctor Fallone said that the results provided experts and parents with a clear message:
| A．The sleeping time that the students have can be changed easily. |
| B．They also had trouble learning new information, completing difficult work and following directions. |
| C．During one week, the children went to bed and awoke at their usual time. |
| D．The teacher should restrict the amount of the sleep of the students. |
E. Gahan Fallone did the study at the Brown Medical School and Bradley Hospital in the state of Rhode Island.
F. The teachers reported that students were, in fact, a little less active at school when they got less sleep.
G. When a child has learning problems, the issue of sleep must be considered among the possible causes.

Caring for animals, tutoring kids, helping seniors: Volunteer hours are more than a graduation must, they are life lessons.
Vilma Sooknanan cleans cat cages, Max Carroll teaches children how to cook and Michael Rosenthal rolls wheelchairs at a hospital.
What does this have to do with high school education?
Everything.
The three – and almost all other South Florida high school students – have to go outside of the classroom to earn their diplomas, doing what schools call “community service”.
Broward public schools require 40 hours to graduate. Palm Beach County public schools require 20, and most private schools require at least that much.
The purpose: To give students the chance to explore a career and create a habit of volunteering.
“We hope that when they finish high school they’ll continue service,” says Mike Roland, student activities officer for the Broward School District.
About half of U.S. public schools require community service, according to a national study. Broward School Board member Bob Parks says encouraging community service has launched all kinds of new projects, including tutoring and food collections.
Sooknanan, a student at South Broward High School, is part of the Humane Society of Broward County’s volunteer program, which is so popular that even the waiting list is closed. Students work one four-hour shift a week for four months, and leave with 64 volunteer hours.
Sooknanan changes litter boxes and puts down fresh newspaper for about 100 cats.
Combined with her volunteer hours at beach cleanups and helping teachers at school, she’s well on her way toward 250 hours, which she hopes will catch the eye of Nova Southeastern University, where she wants to study marine biology.
Carroll, a junior student at South Plantation High, has connected with FLIPANY, a nonprofit organization that offers cheap physical activity and food to low-income families. He helps teach children about cooking and healthy eating.
“It has been a life-changing experience,” says Carroll, who is now leaning toward a career as a sports trainer. "I want to find a career encouraging people to lead a healthier lifestyle.”

Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.
E. Institutions of adult education |
|
76.
Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something which they missed in earlier schooling, get new skills or job training, find out about new technological developments, seek better self—understanding, or develop new talents and skills.
|
77.
This kind of education may be in the form of self-study with proper guidance through the use of libraries, correspondence courses, or broadcasting. It may also be acquired collectively in schools and colleges, study groups, workshops, clubs, and professional associations.
|
78.
Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities; new types of work were being created in an expanding factory system. These and other factors produced a need for further education and re-education of adults.
|
79.
The earliest programs of organized adult education arose in Great Britain in the 1790s, with the founding of an adult school in Nottingham and a mechanics’ institute in Glasgow. The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.

People recognize that continued learning is necessary for most forms of employment today. For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs.Birds that are half-asleep—with one brain hemisphere (半球) alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.
Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.
Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half-asleep during some 32 percent of napping time.
“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say.
The results provide the best evidence for a long-standing assumption that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half-sleeping might be, it’s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg.” He supposes that more examples may turn up when we take a closer look at other species.
72. According to the passage, birds often half sleep because ______.
A. they have to watch out for possible attacks
B. their brain hemispheres take turns to rest
C. the two halves of their brain are differently structured
D. they have to constantly keep an eye on their companions
73. What is implied about the example of a bird’s sleeping in front of a mirror?
A. An imagined companion gives the bird a sense of security.
B. Birds prefer to sleep in pairs for the sake of their security.
C. The phenomenon of birds napping in pairs is widespread.
D. A single pet bird enjoys seeing its own reflection in the mirror.
74. While sleeping, some water animals tend to keep half awake in order to ______.
A. alert themselves to the approaching enemy
B. emerge from water now and then to breathe
C. be sensitive to the ever-changing environment
D. avoid being swept away by rapid currents
75. By saying “just the tip of the iceberg”, Siegel suggests that ______.
A. half-brain sleep has something to do with icy weather
B. the mystery of half-brain sleep is close to being solved
C. most birds living in cold regions tend to be half sleepers
D. half-brain sleep may exist among other species
Mike Maietta was eating lunch when he got a text message from his mom.
“Notre Dame,” it said. “Big envelope!”
Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big obstacle. So Mike and his parents are considering offers from several other colleges and are calculating the costs of tuition, housing and holiday trips home.
This year, money is the driving factor for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and plunging house prices have changed family spending.
“We’re excited that Mike got into eight great schools,” said Mike’s father, an engineer at Microsoft. “But if you consider going to school out of state, you’ve got to think about all of the other costs: moving, flying back and forth for the holidays. You’re looking at about $3,000 a year, just for travel.”
As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased.
Rachel Brown was happy to get a thick envelope from New York University (NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego (UCSD), because of the high cost in New York.
“The tuition for NYU is twice as much as UCSD,” said Rachel, 17. “My mom doesn’t want me to have a big debt when I graduate, and I don’t want that either. I’d have to take out a loan of $15,000. I’ll check and see if there’s any way that NYU can offer me any financial aid.”
More than 7.6 million American students have filled out the Free Application for Students Aid, a 19.9 percent increase over last year.
This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000.
68. Mike may give up Notre Dame because of ______.
A. travel fees B. financial concerns
C. poor exam results D. worries about living far away from home
69. The phrase “Big envelope” in paragraph 2 probably refers to “______”.
A. A text message B. A large gift package
C. An admission letter D. A scholarship letter
70. What can we learn from the passage?
A. The number of American senior students applying for financial aid is increasing.
B. Rachel Brown has given up NYU because of its high tuition and big debts.
C. It is inevitably hard for college students to borrow money to cover costs.
D. An interest-free loan for students helps more students apply for Stanford.
71. The passage mainly focuses on ______.
A. the calculation of different costs including tuition
B. the extremely hard financial situation in America
C. the excitement of students’ being able to enter ideal colleges
D. the financial crisis of families over college entrance
Dear Daughter, 
As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are. Getting into Columbia is a real proof of what a great well-rounded student you are. You should be as proud of yourself as we are.
It is in college that you will discover what learning is about. This will be the period where you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn’t critical for your life, the learning skills you acquire will be something you will treasure forever.
Follow your passion in college. Take courses you think you will enjoy. Don’t be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy. Pick a few friends and become really close to them – pick the ones who are genuine to you. Don’t worry about their grades, looks, or even personalities.
Start planning early. I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is coursework planning or picking a major, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver’s seat – this is your life, and you need to be in control. Being in control feels great.
So please treasure your college years – make the best of your free time, become an independent thinker in control of your destiny fate, learn and grow through your successes and challenges.
May your years at Columbia be the happiest of your life, and may you blossom into just what you dream to be.
Love,
Dad (& Mom)
