On Saturday nights, A.J.Coston doesn’t get a ...

On Saturday nights, A.J.Coston doesn’t get a lot of sleep. Usually three or four times a night, a loud bell rings, a red light flashes, and he has to jump out of his bed. That’s because he’s a weekend volunteer firefighter（消防员）with Loudoun County Fire and Rescue Station 13 in Northern Virginia. During the week, he lives at home with his mom, dad and sister and does his main job which is going to high school.

“I have always wanted to get into firefighting since I was a little kid watching fire trucks go by,” he says. “One day on the Internet I noticed that Loudoun County offered a junior firefighter program.” He was only 16, but he got it.

Fighting fires is dangerous work. Firefighters never stop practicing the skills they need to stay safe. Once Coston learned those skills, he was allowed to work inside burning buildings.

“Teamwork is most important,” he says. “It’s the whole team that puts the fire out.”

Firefighters feel great about helping people. “My most unbelievable call was probably the time four kids were struck by lightning,” says Coston. He will be off to college next fall, building on his dream job. “I’ll get my degree in emergency（紧急情况） medical care. and then work in a fire and rescue company for a while. I want to be a flight doctor on a helicopter in the end, but I will never forget the days as a firefighter. These are my unforgettable experiences,” he says.

Surveys of American teenagers find that about half of them do not get enough sleep on school nights. They get an average of 60 to 90 minutes less than experts say they need.

Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups. Yet many schools start classes as early as seven in the morning.

As a result，many students go to class feeling like Danny，16 years old. He plays two sports，lacrosse and football. He is an active teen—except in the morning. DANNY：“Getting up in the morning is pretty terrible. I’m just very out of it and tired. And through first and second period I can hardly stay awake.”

Michael Breus，a clinical psychologist with a specialty in sleep disorders says：“These aren’t a bunch of lazy kids—although，you know，teenagers can of course be lazy. These are children whose biological rhythms，more times than not，are off.”Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experience a form of depression that could have big effects on their general well-being. It can affect not just their ability in the classroom but also on the sports field and on the road because any tired driver is dangerous，especially a teenager with a lack of experience.

So what can schools do about sleepy students？The psychologist says one thing they can do is start classes later in the morning.

Eric Peterson，head of St.George’s School in the northeastern state of Rhode Island，says，“In the end，schools ought to do what’s the right thing for their students，first and foremost.”And he wanted to see if a 30-minute delay would make a difference. It did.

1.According to the passage，which of the following is the chief cause of sleepy teenagers？

2.According to Michael Breus，________.

3.What is Eric Peterson’s opinion on the issue？

4.What does the underlined word“It”in the last sentence might refer to？

5.What can you infer might follow the passage immediately？

Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.

New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.

The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.

“We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.

The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.

It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.

1.The text mainly advises people ______.

A. to sleep more time                          B. to sleep in on Saturday

C. to sleep scientifically                      D. to sleep little on weekend

2.People with long-term sleep loss ______.

A. are quicker in thinking                   B. may feel refreshed soon after waking up

C. are surely energetic                         D. can have a strong sense of security

3.What can we learn from the text?

A. Most of the Americans get six hours or less of sleep a night.

B. Staying up is worse for those who suffer long-term sleep loss.

C. Traffic accidents have little to do with sleepiness.

D. One in six Americans are all-nighters.

4.Which of the following is the immediate effect of long-term sleep loss?

A. Health problems                             B. Immune system

C. Reaction times                               D. Memory impairment

5.The underlined phrase “bank up” in the last paragraph most probably means ____.

A. pile up               B. pick up              C. add up                     D. build up

In an ideal world, we usually get eight hours of sleep every night, and wake up with enough energy before work. But when we're struggling to balance the responsibilities of everyday life, cutting back on sleep seems to be the only solution. Many of us rely on coffee or energy drinks to get us through the day, instead of making sleep a priority. Sadly, as delicious as it can be, caffeine is not the solution. Being tired not only brings down our energy levels, but also makes us less productive and less motivated. There are concrete steps you can take right now to renew your energy.

Awareness comes first because you have to understand what's going on before you can do anything to change it. Most of us are too busy to notice how fatigue(疲劳) really affects our bodies and minds. What signs of trouble do you regularly display? The patterns of your signs of trouble can give you clues about the negative effects of your fatigue. In addition, it's wise to start thinking about whoever can feel the effects of your fatigue.

Reflecting on the choices you've made can provide clarity, which will help you figure out what needs to be changed. During this reflection, you will be able to understand more about yourself and why you do the things you do. You may decide to forgive yourself for the mistakes you've made. Thinking about the positive aspects of your life will make you feel refreshed and ready to move forward.

Conversing with others not only provides support, but also leads to new perspectives and feedback that can help with treatment and what you need to heal. To start with, have an open mind and an open heart. Limit complaining. Complaints may need to be aired in order to relieve pressure, but if they dominate(占上风), anger will win. Tell the truth. You do not need to tell people everything, but you do need to be honest. Listen carefully because it shows respect.

The fourth step is about renewal—getting rid of what is bringing you down and making a fresh start. It's helpful to break the process down. It is easier to make small adjustments than big ones. On occasion, the small steps alone can remove fatigue. For instance, you may not need to change your career but change emphasis. If you feel hopelessly dragged down by fatigue, self­care may be the best prescription.

Younger adults who get either little sleep or a lot of it may see a greater expansion in their waistlines（腰围）over time, a study published suggests. Researchers found that among black and Hispanic adults younger than 40, those who typically slept for five hours or less each night had a greater accumulation of belly fat over the next five years, versus（相比于） those who averaged six or seven hours. Those who slept eight hours or more in bed each night also showed a bigger fat gain - but it was less obvious than that seen in "short sleepers."

The study, reported in the Journal Sleep, does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration - particularly a lack of sleep - to weight gain and even to higher risks of diabetes(糖尿病) and heart disease. Among participants younger than 40, the study found, those who said they slept for five hours or less each night gained more belly fat than those who averaged six or seven hours of sleep. On average, short sleepers showed a 32 percent gain in visceral（内脏的）fat, versus a 13 percent gain among those who slept six or seven hours per night, and a 22 percent increase among men and women who got at least eight hours of sleep each night. A similar pattern was seen with superficial abdominal（腹部）fat.

The findings, according to lead researcher Dr. Kristen G. Hairston, support the belief that sleep habits affect weight and health in general. "Sleep is an important part of your overall health - not just in whether you're tired during the day," she said.

There may be indirect effects; people who get too little sleep may be too tired during the day to exercise, while those who spend a lot of time in bed may spend less time being active, relative to people who sleep fewer hours. Research also suggests that sleep loss alters people's levels of appetite-regulating hormones（荷尔蒙）- which could, in theory, cause them to overeat. Depression, which often affects people's sleep and has been linked to weight gain, could also be a factor, Hairston noted.

1.Who may have the higher risk of being fat over the next five years?

A. Jack, a Hispanic man, aged 35, sleeps for 3 hours every night.

B. Candy, a black woman, aged 41, sleeps for about 5 hours every night.

C. Bob, an American, aged 50, sleeps for more than 12 hours every day.

D. John, a student in Africa, sleeps for more than 6 hours every week.

2.What does the study, reported in the Journal Sleep find?

A. Too little or too much sleep directly gives rise to the fat gain.

B. People are subject to heart disease due to the lack of sleep.

C. It is admitted that sleep plays an important part in our health.

D. Researchers find a longer sleep time is better for our health.

3.What does the lead researcher Dr. Kristen G. Hairston agree with?

A. People should do some exercise in their daily life.

B. There is a close link between sleep habits and health.

C. More nutrition is greatly needed when we lack sleep.

D. More and more people tend to sleep less than before.

4.What can we infer from the passage?

A. Younger adults getting little or much sleep may become fat.

B. We are supposed to do exercise as much as possible to keep fit.

C. We should keep a good sleep habit to improve our health.

D. We have to spare no efforts to drive depression away.

5.What’s the best title of the passage?

A. Sleep Habits Linked to Fat Gain in Younger Adults.

B. Doing Exercise Is the Best Way to Keep Fit.

C. Our Waistlines Can Be Driven Away Right Now.

D. Diabetes No Longer bother all of Young People.

Getting enough sleep on a regular basis is one important way to protect the health of your heart. Poor sleep is associated with a range of cardiovascular(心血管的) problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health.

Research indicates that poor-quality sleep—and waking too early in particular—is associated with increased inflammation(炎症) among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart.

Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary(冠状的) heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning.

After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they analyzed data taking gender(性别) into account, researchers found a relationship between inflammation and sleep existed for women, but not for men.

1.When a person suffers from sleep disorder _______.

A. he/she is sure to have cardiovascular problems

B. he/she may be in a state of poor health

C. he/she must be in danger of heart disease

D. he/she might get on poorly with others

2.What is the purpose of the author in writing the passage?

A. To stress how to have a good sleep in daily life.

B. To show a good sleep is more important to women.

C. To describe different kinds of sleep problems.

D. To encourage readers to sleep more.

3.The researchers did the study _______.

A. to find a cure for women with heart disease

B. to know what contributes to inflammation

C. to look into the relationship between sleep quality and inflammation

D. to track the lifestyle of men and women

4.Which of the following is the suitable title for the passage?

A. Poor Sleep Results in Problems Only for Adults

B. Lack of Sleep Can Lead to Much Inflammation

C. Sleep Loss Is to Increase Anxiety Disorders

D. Women’s Sleep Habits May Affect Heart Health

On the night of December 8, 1992, when he was standing in a parking lot talking to friends, Tracy March jumped to the top of a car, as he had done a hundred times before. This time, though, Tracy lost his balance. His head struck the ground, hard.

All night, Cory, Tracy’s mother, stood next to her son, who was lying in a hospital bed, his brown eyes fixed in a lifeless stare. She remembered that Tracy had once mentioned organ donation. Maybe I can spare another family this pain, she thought. When the time came, she and her husband Bill signed the forms permitting his organs to be donated.

Tracy was declared dead the next day. Twenty-four hours later, in a Boston hospital, Tracy’s liver was made part of my husband, David, who was suffering from a hopeless liver disease.

Months later, we learned from the local organ bank that the donor’s parents wished desperately to meet someone who had gained life through the gift from their son. A meeting was arranged by the organ bank to bring together two families linked by the most bittersweet ties imaginable.

The meeting was risky, but worth it. We talked for 3 hours. They showed us a picture of Tracy. We learned how he had lived and died. We learned something about Bill and Cory too.

For the Marches, seeing David and knowing he was well seemed to ease their suffering. I’ll never forget seeing David’s tall figure stopped over Cory, her arms around his waist, as a mother would hug a son. For a long time they held each other tight. It was hard to know if she was saying hello or good-bye. Maybe she was saying both.
