Sleep is just as important as diet and exercise, and not getting enough sleep can lead to obesity, heart trouble and other health problems. Now scientists are adding more wake-up call to that list: lack of sleep damages the brain.

People who regularly have trouble falling asleep and staying asleep (one study drew the line at 6.8 hours ) show changes in brain-----actual shrinking(缩小)，in some cases--- in area important for memory and problem solving.

“We’ve always believed that we can take the weekend to catch up and be fine,” says Sigrid Veasey, a researcher in University of Pennsylvania, but that may not be the case. When she stopped mice from sleeping for 3 days, they lost 25% to 30% of the neurons (神经元) important for focused attention---- and these remaining were damaged. What’s more, these brain cells never grew again.

Clearly, something important is happening while we sleep, but exactly what sleep does for the brain has been a mystery. That’s why scientists got excited when researchers at the university of Rochester Medical Center recently offered a new theory. While observing the brains of sleeping mice, they discovered a kind of brain-cleaning system that clears away neural waste, the buildup of which is connected with Alzheimer’s.

In another study, young healthy people whose sleep was limited to 7 hours per night for one week showed damaged brain function. Scarier is that with long-lasting short sleep, you may feel fully rested. When study subjects were limited to 4 hours of sleep for 5 days, they reported feeling very tired following the first night but they didn’t get any sleepier after that.

What’s more, a 15,000 –person study found that getting an average of less than 5 hours of sleep per night for several years resulted in a decrease in memory performance equal to the brain aging 2 years.

Today, we will talk about diet and weight loss. Exercise is important if you want to get in good shape. To have a perfect body, someone go to extremes to lose weight. 1.

In the weight loss industry, there is never a lack of ideas about how to lose weight. Consider the “Sleeping Beauty diet,” where you sleep your way to weight loss. You cannot eat if you are sleeping, or so the theory goes.

2. The tapeworm (绦虫) is said to help people lose weight by eating the food that is stored in their stomach. But first you have to be willing to eat the little worm. This may be more trouble than many people want.

Strange, new diets and exercise programs arrive on the market every day. 3.　 The weight loss industry takes in billions of dollars each year, and it is growing.

Experts say there is no single diet plan that works best for everyone. Many experts agree on one thing: you must use or burn off more calories than you take in to lose weight. When you eat more calories than your body needs, it stores that extra energy as fat.

4. A pound of fat is equal to about 453 grams or 3,500 calories. To lose that fat in a week, you have to burn off at least that amount in calories or eat that much less.

5. Eat fewer calories and increase physical activity so that you burn off more.

A. Then there is the tapeworm diet.

B. Calories are a measure of energy in food.

C. But no plan has come out as a clear winner.

D. The best thing to do is to combine both ideas.

E. These lead to a big industry — weight loss industry.

F. But experts say exercise alone is not enough if your goal is to lose weight.

G. Each one promises to help people lose weight and get a beautiful body.

Sleep is a basic human need, as basic as the need for oxygen. Getting a good night’s sleep is not only directly related to how we feel the next day, but to our long-term health as well. However, many of us suffer from insomnia (失眠). Even more of us report at least one night of restless sleep per week. This is a serious problem.

Well, how can we make sure that we rest well and stay healthy? Here are some suggestions.

If you can’t sleep in the middle of the night, don’t get up. The bright light will affect your body clock and worsen your insomnia. Stay in bed!

Avoid short sleep during the day, except for a brief ten to fifteen-minute sleep between 2:00 and 4:00 P.M.

Limit your time in bed to the average number of hours you’ve actually slept per night last week. Don’t try to make up for lost sleep. It can’t be done.

Get regular exercise each day, but finish at least six hours before bedtime. Exercising in the evening can help keep you awake.

Take a hot bath for thirty minutes within two hours of bedtime. The bath will warm you, relax you, and make you feel sleepy.

Keep our bedroom dark, quiet, and well ventilated (通风).

Keep a regular schedule seven days a week. Avoid sleeping late on weekends. Although it may feel good while you’re doing it, sleeping late on weekend can lead to insomnia during the week.

Don’t drink alcohol (酒精). Although, having a drink before bed makes you sleep, alcohol loses its effects after a while. The secondary effects of alcohol can wake you up during the second half of your night’s sleep.

Keep the face of the clock in your bedroom turned away, and don’t find out what time it is when you awaken in the night.

1.The first paragraph serves as a(n) __________.

A. argument　　　　 B. introduction

C.　 comment　　　　 D. explanation

2. Which of the following is NOT advised for a good night’s sleep?

A. Staying in bed after failing to sleep.

C. Don’t drink alcohol before sleeping.

D. Preventing the wind from blowing into your room.

3. To sleep well, you need to __________.

4.The text mainly about__________ .

Sleep is a basic necessity of life and it is as important to our health as air, food and water. When we sleep well, we wake up feeling energetic, alert and ready to face daily challenges. When we don’t every part of our lives can suffer.

A survey made by the 2002 National Sleep Foundation (NSF) in America found that 74 percent of American adults are experiencing a sleep problem a few nights a week or more and 39 percent get less than 7 hours of sleep each night and want to have a sleep during the day.

Getting enough continuous quality sleep influences how we feel and perform next day. Getting enough sleep refers to the amount of sleep you need not to feel tired next day. Although sleep experts generally recommend an average of 7-9 hours each night, some people can get along with less while others need as many as ten hours to feel energetic next day. Sleep requirements vary(变化)over the life cycle. Newborns and babies need a lot of sleep and have several periods of sleep throughout a 24-hour time period. Teenagers’ sleep patterns turn to a later sleep-wake cycle, but they still need around 9 hours of sleep. Throughout adulthood, even as we get older, we need 7-9 hours of sleep. Sleep patterns may change, but the need for sleep remains the same.

According to the 2002 poll. Over 80 percent of American adults believe that not getting enough sleep leads to poor performance at work, risk of injury, poor health and difficulty getting along with others. Often, people become easily annoyed due to lack of sleep. Recent research suggests that lack of sleep also leads to approximately 100,00 sleep-related traffic accidents each year and results in 1,500 deaths.

If you are having sleep problems, turn to a sleep diary published by the National Sleep Foundation. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can find some reasons for poor sleep. Establishing a regular bed and wake-up schedule may also help you sleep well. Besides, talking to your doctor or a sleep specialist is of great help. Most sleep disorders can be successfully treated once properly diagnosed(诊断).

As we all know, sleep is very important and necessary. I would love everyone to develop the following four habits to have better sleep without needing the alarm（闹钟）wake-up call.

1.If you eat much food an hour before you go to bed, your body will hate you, because your body needs time to digest while you are still awake.

2.When I hear on TV that people just need 30-minute exercise a week, I think that’s wrong. Every person should get 30-minute exercise every day. When you exercise, your body uses energy and feels tired. You have to recover from the tiredness. 3. The harder you exercise your body, the faster it falls to sleep and the better it sleeps.

Turn the TV off. There are a few shows I still watch, but they will never get in my way of (妨碍) sleep. The bedroom is only for sleeping and rest. 4..

5.A question to ask yourself: If I didn’t have an alarm, what time would I get up? If that time is the time you need to get up, you should probably throw away the alarm. If the time you actually get up is much later than the time you need to get up, make great changes to your way of life and the time you go to sleep. No one should need an alarm.

A. Exercise for at least 30 minutes every day.

B. Don’t eat any food 4 hours before you sleep.

C. Throw away the alarm.

D. Sleep is one of the most important things in our lives.

E. Your body recovers when you are sleeping.

F. Try to get up as early as you can.

G. Take the TV out of your bedroom.
