Insufficient sleep is linked with changes in hormone levels that may stimulate（刺激）appetite. A series of studies in recent months have shown that the less people sleep, the heavier they tend to be.
American researcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people"s self-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inversely correlated was total sleep time decreased, BMI increased, except in the severely obese group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity on patients," the study said. "Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship."
In November 2004, researchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obese and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obese than people who slept between seven and nine hours per night.

举一反三
At one time, people suffering from the disease were said to be“getting old”.The disease was though to be a natural part of growing old, but it is now known that Alzheimer’s disease strikes young and old alike. It is an organic(器官的)disease that destroys brain cells.
Alzheimer’s disease affects the patient’s memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking. Then the patient’s memory begins to fail. He may forget dates, telephone numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms(症状)often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus(病毒).It may be caused by a poisonous substance(物质)in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
小题1:The main idea of the passage is that Alzheimer’s disease________.
| A．is a terrible part of the aging process |
| B．is an organic disease that affects young and old |
| C．can be cured by physical treatment |
| D．causes forgetfulness |
A. forgetfulness B. difficulty in speaking
.loss of sight D. loss of the ability to walk
小题3:According to the passage, which of the following may be a cause of Alzheimer’s disease?
| A．Poisons produced by the brain. | B．Getting old. |
| C．A virus. | D．Lack of exercise. |
| A．operation | B．a change in environment |
| C．medicines | D．physical treatment and exercise |
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce.
Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt（酵母乳）that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “low fat.” The “low fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”

Orbach must at times think the anti-diet message of her book “fat is a Feminist Issue(女权主义问题)”has been lost since it was written more than 20 years ago.
Girls, boys, old people --even the famously well-rounded female population of Fiji are falling victims(牺牲品) to fat fear.
"If anything, the situation has got much, much worse. We now have kids as young as eight and women in old people’s homes worried about the way they look." Orbach said.
Even though it has been proved that repeated dieting results in a little more than regaining most of the lost weight, constant dieting has become a way of life for many women. 48 per cent of British women aged 25 to 35 were on some kind of diet and 20 per cent of young women dieted all or most of time. Some of them said they would pop a pill to give them their beautiful shape, even if it meant risking
their health. Worldwide, 70 million people have an eating disorder. Most are women, but men are increasingly affected, too.
More than half the women and two thirds of the men in Britain weigh too much. while in the United States more than one quarter of adults and about one in five children are overweight. The idea that female beauty is a very thin body could be changed, if clothing factories and magazines showed images(形象) of women of all shapes instead of selecting skeletal-like models and stick-thin actress.
But that is easier said than done.
To get the message across, Orbach is also considering talking to pop stars such as Victoria Beckham and Geri Halliwell, both of whom have admitted__________________.

"It takes a long time to feel the effects of knee osteoarthritis (骨关节炎) — and once you do, it is too ]ate," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School"s department of physical medicine.
"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said. "They are better for your feet than stiletto heels, but just as had for your knees."
The idea that high heels are bad for your health isn"t new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained (扭伤) ankles and back problems.
But in 1998,Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage (软骨) surrounding the knee.
The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.
"This study confirms what we all intuitively (直觉地) know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

Economists from the University of Warwick, central England, and from Dartmouth College, New Hampshire, looked at data on the mental health of two million people from 80 countries.
In Britain, the probability of depression for men and women peaks at around 44 years of age, Warwick University said in a press release.
In the United States, though, ________________________between men and women. Among women, unhappiness peaked at around the age of 40, whereas among men, it was about 50.
But the U-shape of happiness is constant around the world, and mid-life depression occurs regardless of marital status(婚姻状况), changes in job or income.
The study appears in Social Science & Medicine, published by the Dutch publishing house Elsevier.
"It happens to men and women, to single and married people, to rich and poor, and to those with and without children." said co-author Andrew Oswald.
One possibility may be that people realize they won"t achieve many of their ambitions at middle age. The researchers said.
Another reason could be that after seeing their fellow middle-aged peers begin to die, people begin to value their own remaining years and embrace life once more.
But the good news is that if people make it to aged 70 and are still physically fit, they are on average as happy and mentally healthy as a 20-year old.
"For the average persons in the modern world, the dip in mental health and happiness comes on slowly, not suddenly in a single year," Oswald said. "Only in their fifties do people emerge from this low period.
1.Which sentence in the passage is the closest in meaning to the following one?
There are chances that the middle-aged people will realize their ideal is likely to be unattainable.
