Passage FourAfter a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!46. A good title for this passage is ______.A. SleepB. Good HealthC. DreamsD. Work and Rest
DScience can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer. Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their ani mal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.67．What does the text mainly discuss?A．What pets bring to their owners.B．How pets help people calm down.C．People's opinions of keeping pets.D．Pet's value in medical research.

共用题干Obesity:the Scourge of the Western WorldObesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to state-ments before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight,and 250 million are obese.Professor Bernhard Ludvik of Vienna General Hospital said:“Obesity is a chronic ill-ness.In Germany,20 percent of the people are already affected,but in Japan only one per-cent.”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.Professor Friedrich Hopichler of Salzberg said:“We are living in the new age(but)with the metabolism of a stone-age man.”“I have just been to the United States.It is really terni-ble.A pizza shop is springing up on every corner. We have been overrun by fast food and Co-ca-Cola-ization.”Many of the experts stressed that obesity was a potential killer. Hopichler said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease.Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs.“Though the health insurance pays for surgery( such as re-ducing the size of the stomach)when the body-mass index is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.70 meters.One should start earlier.”Ludvik said that prevention should begin in school.“Child obesity(fat deposits)correlates with the time which children spend in front of TV sets.”The consequences were only apparent later on. No more than fifteen percent of obese people lived to the average life ex-pectancy for their population group.What is the correlation between body weight and heart disease and blood pressure?A: Ten percent less body weight means ten percent less risk of heart disease and high blood pressure.B: Thirteen percent more body weight means ten percent more risk of heart disease and high blood pressure.C: The more body weight one gains,the more risk of heart disease and high blood pressure he has.D: The less body weight one gains,the more risk of heart disease and the less risk of high blood pressure he has.
共用题干Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.People who take regular afternoon naps______.A:where fewer people die from heart problemB:whether they have the risk of heart attack,heart failure or strokeC:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too
共用题干第三篇 Smart ExerciseDoctors are starting to find more and more information that suggests a connection between exercise and brain development.Judy Cameron,a scientist at Oregon Health and Science University,studies brain development.According to her research,it seems that exercise can make blood vessels,including those in the brain,stronger and more fully developed.Dr. Cameron claims this allows people who exercise to concentrate better. As she says:"While we already know that exercise is good for the heart,exercise can literally cause physical changes in the brain."The effects of exercise on brain development can even be seen in babies.Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active.With babies,even a{ittle movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in the importance of exercise.She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses.They need to establish a connection between motion and memory.In this way,as they get older,children will begin to associate physical activity with higher learning,"says Margaret. Older people can beef up their brains as well.Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week.The exercise does not have to be very difficult,but it does have to increase the heart rate.Also,just like the motion for infants,exercise for older people should involve some complexity.Learning some new skills or motions helps to open up memory paths in the brain that may not havebeen used for a long time.For most people,any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood.And your brain can benefit from as little as two to three hours of exercise a week. To be beneficial,exercise for older people shouldA:be done in a group. B: be done on a daily basis.C: involve great difficulty. D:increase the heart rate.

Cultural exchange has a longer history than political exchange, a more profound impact than economic exchange. As time goes by, things begin to change. Many prominent figures and events will fade into history, but culture lives on. It gets ever stronger and vital with the passage of time, and has an enduring influence on the way we think and live. Different geographies have nurtured a variety of cultures, each with unique feature and attributes. They are like the shining stars in the sky, adding radiance to each other and illuminating the vast universe.
