M: Ann exercises？ Is that because our arms are too fat and lacking energy？
W: Actually, tint's not the main reason. They say that arm exercises are an ideal way to become physically fit.
M: But don't arm exercises raise your blood pressure？
W: Yes they do. But the article I read mentioned ways to compensate for that.
M: How？
W: By adding leg exercise so the arms don't do all the work. It's said that the more of the body that's involved in the exercise, the better.
M: And in turn, I'm sure that there is a greater chance of losing weight.
W: Sounds right to me.
M: So, what exercises do the experts recommend？
W: They mentioned quite a few. But some of the more popular ones are cycling with special bicycles that make you use both your anus and legs, and walking energetically while you wear arm weights.

听力原文： A new study suggests that very young children who watch a lot of television may have attention problems later in school.
Children with attention problems cannot sit still or control their actions. They talk too much, lose things, forget easily and are not able to finish tasks.
The new study tested the idea that television watching by very young children is linked to attention problems by the age of seven. It involved more than 1,300 children. There were two groups of children, aged one and three. Researchers asked the parents how often the children watched television. The parents also described their children's actions at the age of seven using a method that can tell if someone suffers from attention problems.
The children who watched a lot of television at an early age were most likely to have attention problems. Every hour of watching television increased the chances of having attention problems by about ten percent. For example, children who watched three hours a day were thirty percent more likely to have attention problems than those who watched no television.
One of the researchers said there are other reasons why children should not watch television. Earlier studies have linked it with children becoming too fat and too aggressive. Other experts say the new study is important, but more work needs to be done to confirm the findings and better explain the cause and effect.
(30)
A．Attention problems.
B．Participating problems.
C．Communication problems.
D．Speaking problems.

A New Drug for Losing Weight
Scientists have developed a slimming drug that successfully suppresses appetite and results in a dramatic loss of weight without any apparent ill effects. The drug interferes with appetite control and prevents the build-up of fatty tissue. More importantly， the drug appears to prevent a serious decline metabolic rate——causing tiredness and lethargy——which is typically associated with living on a starvation diet. S a result， mice taking the drug lost 45 percent more weight than mice fed the same amount of food， which compensate for the lack of food by becoming more sluggish.
The scientists， from the Johns Hopkins University in Baltimore， said that C75 is likely to produce a similar effect on humans because appetite control in the brain is thought to be based largely on the same chemical pathways as those in mice. "We are not claiming to have found the fabled weight-loss drug. What we have found， using C75， is a major path way in the brain that the body uses naturally in regulating appetite at least in mice，" said Francis Kuhajda， a pathologist and senior team member. "We badly need effective drugs for weight loss. Obesity is a huge problem.
We"re hoping to explore the possibilities of this new pathway，" he said.
Discovering a biochemical. Pathway in the brain that controls appetite raises new prospects for eloping slimming aids. Research on leptin， a hormone produced in fatty tissue for controlling fat deposits， has so far failed to produce the expected slimming drug break-through. The latest study， published in the journal Science， showed that even moderate doses of C75 produced a significant loss of appetite， which returned to normal after a few months.
The scientists believe that C75， which they produced synthetically in the laboratory， binds to an enzyme called fatty acid sythase， which is involved in storing excess food intake as fat.
Inhibiting enzyme causes a build-up of a chemical in the liver which acts as a precursor to fat deposition. This precursor is thought to have an indirect effect on the brain， causing appetite suppression.
Normally， when animals fast， a hormone called neuropeptide Y increases sharply in the appe-tite control centers of the brain， stimulating the desire for food. However， when animals are given C75， levels of this hormone fall， leading to a loss of interest in food. Dr Kuhajda said discovering that C75 has no effect on metabolic rate is one of the most significant findings of the study. "If you try to lose weight by starving， your metabolism slows down after a few days，" he said. "It"s a survival mechanism that sabotages many diets. We see this in fasting mice. Yet metabolic rate in the C75-treated mice doesn"t slow at all. "Further animals studies will be needed before C75 could be tested on humans.
Living on a starvation diet may result in __________. 查看材料
A.a dramatic loss of weight without any ill effects
B.a long-term loss of interest in eating
C.a slowdown of fat deposition
D.fatigue and inactivity

Now, a new American study demonstrates what may be a good effect connected to drinking coffee. It found a link between drinking coffee and a decrease in the risk of gallbladder disease in men. The findings are reported in The Journal of the American Medical Association.
The gallbladder is an organ in the body that stores bile. (48) . Someone with gallbladder disease may experience severe pain in the stomach after eating fatty foods. Cholesterol in the bile can form. painful gallstones. Lack of physical activity and being overweight are the two main causes of gallstone disease.
Researchers from the Harvard School of Public Health in Boston, Massachusetts organized the study. They say coffee has several effects that could reduce the risk of gallstone formation (49) . The new study involved 46,000 men. The men were all doctors or health care specialists between the ages of 40 and 75 years old. None of them bad a history of gallbladder disease.
(50) . The researchers found that more than 1,000 of the men reported having gallstone disease. More than 80 percent of those men required an operation to remove the gallbladder.
A. For years, scientists have argued about the health effects of drinking coffee
B. Bile helps the body break down fat in food
C. Doctors have found a method to cure the disease
D. The men were observed for 10 years
E. That is because coffee contain caffeine
F. Earlier studies had offered conflicting results, however

Calories
For years now, calories have been all the rage—people are Counting them and cutting them, and you'd be hard pressed to find something at the supermarket that does hot list its calories per serving somewhere on the package. But have you ever wondered what exactly a calorie is？
What is a Calorie
A caloric is a unit of energy. We tend to associate calories with food, but they apply to anything containing energy. For example, a gallon (about 4 liters) of gasoline contains about 31,000,000 calories.
Specifically, a caloric is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius(1.8 degrees Fahrenheit). One caloric is equal to 4.184 joules(焦耳), a common unit of energy used in the physical sciences. Most of us think of calories in relation to food, as in "This can of soda has 200 calories." It turns out that the calories on a food package are actually kilocalories (1,000 calories=1 kilocalorie). The word is sometimes capitalized to show the difference, but usually not. A food calorie contains 4,184 joules. A can of soda containing 200 food calories contains 200,000 regular calories, or 200 kilocalories. A gallon of gasoline contains 31,000 kilocalories.
The same applies to exercise when a fitness chart says you burn about 100 calories for every mile you jog, it means 100 kilocalories. For the duration of this article, when we say "calorie", we mean "kilocalorie".
What Calories Do
Human beings need energy to survive—to breathe, move, pump blood—and they acquire this energy from food.
The number of calories in a food is a measure of how much potential energy that food possesses. A gram of carbohydrates(碳水化合物) has 4 calories, a grain of protein has 4 calories, and a gram of fat has 9 calories. Foods are a compilation of these three building blocks. So if you know how many carbohydrates, fats and proteins are in any given food, you know bow many calories, or how much energy, that food contains.
If we look at the nutritional label on the back of a packet bf maple-and-brown-sugar oatmeal(麦片), we find that it has 160 calories. This means that if we were to pour this oatmeal into a dish, set the oatmeal on fire and get it to burn completely(which is actually pretty tricky), the reaction would produce 160 kilocalories (remember: food calories are kilocalories) enough energy to raise the temperature of 160 kilograms of water 1 degree Celsius. If we look closer at the nutritional label, we see that our oatmeal has 2 grams of fat, 4 grams of protein and 32 grams of carbohydrates, producing a total of 162 calories(apparently, food manufacturers like to round down). Of these 162 calories, 18 come from fat(9cal×2g), 16 come from protein(4cal×4g) and 128 come from carbohydrates(4cal×32g).
Your Caloric Needs
Just how many calories do our cells need to function well？ The number is different for every person. You may notice on the nutritional labels of the foods you buy that the "percent daily values" are based on a 2,000 calorie diet—2,000 calories is a rough average of what a person. needs to eat in a day, but your body might need more or less than 2,000 calories. Height, weight, gender, age and activity level all affect your caloric needs. There are three main factors involved in calculating how many calories your body needs per day:
-Basal metabolic rate(基本新陈代谢率)
-Physical activity
-Thermic(热的) effect of food
Your basal metabolic rate(BMR) is the amount of energy your body needs to function at rest. This accounts for about 60 to 70 percent of calories burned in a day and includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning and the body temperature stabilized. In general, men have a higher BMR than women.
