考题 共用题干 The Mind-Body ConnectionsNorman Cousins was a famous American magazine editor. In 1964,he returned from an overseas trip and then became very ill.In the hospital,he had a terrible pain and couldn't move his body.Doctors told him he had a serious disease called ankylosing spondylitis(强直性脊柱炎)and said he had only 1 chance in 500 of surviving. They gave him powerful drugs,but his condition only got worse.Cousins had read about a theory that negative emotions can harm your health.He believed that positive emotions were good for one's health,and he decided to try an experiment.He would fill his days with good feelings and laughter and see if that might improve his condition.He left the hospital and moved into a hotel room.There,he got a large supply of funny TV programs and copies of old Marx Brothers movies and cartoons.He also hired a nurse to read funny stories to him.His plan was to spend the whole day laughing and thinking about happy things.On his first night in the hotel,Cousins found that laughing at the movies helped his body produce chemicals that reduced pain.For the first time in weeks,he could sleep comfortably for a few hours.Every time the pain came back,he watched anotherfunny movie and laughed until he felt better.Over time,Cousins was able to measure changes in his body with blood tests.He found that the harmful chemicals in his body decreased at least 5 percent every time he watched a funny movie.After a short time, he was able to stop taking all of his medications.Finally his condition improved so much that he could go back to work.Cousins later wrote a book about how laughter and happiness helped him to survive a deadly illness. Many people didn't believe his story and said that his doctors were wrong about his disease.But since then, research has found that emotions do have a strong effect on physical health,and experiments found that laughter can help to reduce pain.Scientists today are working to understand the ways that our minds affect our bodies.Cousins spent a lot of time laughing every day.A:RightB:WrongC:Not mentioned

考题 共用题干 Eating Potatoes Gives Your Immune System a BoostEating potatoes is not only good for bowel health,but also for the whole immune system,especially when they come in the form of a potato salad or eaten cold.In a study on an animal model,researchers in Spain found that pigs fed large quantities of raw potato starch(RPS)not only had a healthier bowel,but also decreased levels of white blood cells,such as leucocytes and lymphocytes in their blood .White blood cells are produced as a result of inflammation or disease, generally when the body is challenged.The general down-regulation of leucocytes observed by the Spanish researchers suggests an overali beneficial effect,a generally more healthy body.The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.In what was the longest study of its kind,pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health."The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch,"said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,Spain.Humans do not eat raw potatoes,but they do eat a lot of foods that contain resistant starch,such as cold boiled potatoes,legumes,grains,green bananas,pasta and cereals.About 1 0 percent of the starch eaten by human is resistant starch-starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments .Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).Immunology expert Lena Ohman's team previously found that the overall lymphocyte levels do not vary for IBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting,and a diet of resistant starch may be worth trying in lBS patients.Ohman is currently at the Department of Internal Medicine,Goteborg University,Sweden.The study is published in the journal Chemistry and Industry,the magazine of the SCI. What does the reduction in leucocyte levels in the body mean?A: It may mean the reduced levels of inflammation.B: It may mean somewhere in the body is inflamed.C: It means that the body is challenged.D: It means that the body cannot produce leucocytes any more.

考题 共用题干 第一篇ObesityObesity refers to the medical condition characterized by storage of excess body fat. The human body naturally stores fat tissue under the skin and around organs and joints.Fat is critical for good health because it is a source of energy when the body lacks the energy necessary to sustain life processes,and it provides insulation and protection for internal organs.But too much fat in the body is associated with a variety of health problems.Most physicians use the body mass index(BMI)to determine desirable weights.BMI is calculated as weight divided by height and people with a BMI of 27 or above are considered obese.Weight-height tables,such as those published by the Metropolitan Life Insurance Company,are also used as general measures of desirable weight ranges.These tables assign a range of weights for a particular height.For example,a man of 1.8m has a desirable range of 66 to 83 kg,with an average of 75 kg. A woman who is 1.6 m has a desirable range between 53 and 70 kg,with an average of 62 kg.The BMI and weight-height tables only provide rough estimates of desirable weights and scientists recognize that many other factors besides height affect weight. Weight alone may not be an indicator of fat,as in the case of a body-builder who may have a high BMI because of a high percentage of muscle tissue,which weighs more than fat. Likewise,a person with a sedentary lifestyle may be within a desirable weight range but have excess fat tissue.Obesity increases the risk of developing disease.According to some estimates,almost 70 percent of heart disease cases are linked to excess body fat,and obese people are more than twice as likely to develop high blood pressure.Obese women are at nearly twice the risk for developing breast cancer,and all obese people have an estimated 42 percent higher chance of developing colon cancer. The risk of medical complications particularly heart disease increases when body fat is distributed around the waist,especially in the abdomen.This type of upper body fat distribution is more common in men than in women.The social and psychological problems experienced by obese people are also formidable.Stereotypes about"fat"people are often translated into discriminatory practices in education,employment, and social relationships.The consequences of being obese in a world where people had better be "thin"are especially severe for women,whose appearances are often judged against and ideal of exaggerated slimness.If we say that"fat is critical for good health,"we mean that_________.A:fat people should be criticizedB:fat is very important for people to keep healthyC:people should be fat if they want to be healthyD:having much fat in the body is certainly associated with health problems

考题 共用题干 Young Adults Who Exercise Get Higher IQ ScoresYoung adults who are fit have a higher IQ and are more likely to go on to university,reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.The results were recently published in the Proceedings of the National Academy of Sciences (PNAS)The study involved 1 .2 million Swedish men doing military service who were born be-tween 1950 and 1976 .The research group analyzed the results of both physical and IQ tests the youngsters took right after they started serving the army.The study shows a clear link between good physical fitness and better results for the IQ test. The strongest links are for logical thinking and verbal comprehension.But it is only fitness that plays a role in the results for the IQ test,and not strength.“Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen,”says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. “This may be one of the reasons why we can see a clear link with fitness,but not with muscular strength .We are also seeing that there are growth factors that are important.”By analyzing data for twins,the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and higher IQ.“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Maria Aberg,researcher at the Sahl-grenska Academy and physician at Aby health centre.“This being the case,physical education is a subject that has an important place in schools,and is an absolute must if we want to do well in maths and other theoretical subjects.”The researchers have also compared the results from fitness tests during national service with the socio-economic status of the men later in life.Those who were fit at 18 were more likely to go into higher education,and many secured more qualified jobs.The researchers in this study come from_______.A: Aby health centreB: the Swedish armyC: the National Academy of SciencesD: a Swedish university and its affiliated hospital
