Scientists have long been keen to prove that love gives us health 4too. Researchers cant say for sure that a lover is more important than a loving family

14、 or warm friendship when it comes to wellness. But they are learning more about how a romantic partner makes us 5, with health gains that 6from faster healing and better control over illnesses to living longer. The benefits of love are 7and measurable. A study last year from the University of Pittsb

15、urgh found that women in good marriages have a much lower risk of heart disease than those in high-stress relationships. The National Love and Health Study has been 8more than a million subjects since 1979. The study shows that married people live longer, have fewer heart attacks and lower cancer ra

16、tes, and even get pneumonia less frequently than singles. A new study from the University of Iowa also found that cancer patients with a strong sense of connection to others and in 9relationship were better able to fight off cancer.

18、person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.B)The World Health Organization recommends using a formula that takes into account a persons height and weig

19、ht. The “Body Mass Index“(BMI)is calculated by dividing the person s weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of ov

20、er 30 is considered to be obese.C)However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Another shortcoming is that it is

21、 not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program(NCEP)in the USA and the International Diabetes Foundation(IDF)are starting to define obesity in adults simply in te

22、rms of waist circumference.Health Effects of ObesityD)Over 2000 years ago, the Greek physician Hippocrates wrote that “persons who are naturally very fat are apt to die earlier than those who are slender“. This observation remains very true today. Obesity has a major impact on a persons physical, so

23、cial and emotional well-being. It increases the risk of developing diabetes mellitus type 2(“mature onset diabetes“)and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obes

24、ity and coronary heart disease is also well-known. CancerE)Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,

25、893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.F)The link between breast cancer and nutritional stat

26、us is thought to be due to the steroid hormones, oestrogen and progesterone, which are produced by the ovaries, and govern a womans menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link co

27、uld explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resulting in lower predisposition to breast cancer.G)The Times

28、newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!AgingH)Research published by St Thomas Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a woman s biol

29、ogical age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a womans biological age, and although the study only involved wom

30、en, the lead researcher Professor Tim Spector believes the finding would also apply to men.I)The aging effect was determined by measuring the length of telomeres, tiny “caps“ on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the “chrom

31、osomal clock“ because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It is believed that excess bod

32、y fat and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres. Dementia J)Recent research(2005)conducted in the USA shows that obesity in middle age is linked

33、 to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.K)Scientists from the Aging Research Centre at the Karolinska Institu

34、te in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enabl

35、e people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia. Other ProblemsL)The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research

36、 conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional “palpation“ examination, the danger being greatest for those women who are overweight or obesea growing proportion of mothers. This means that such women are not getting

37、 the treatment required to turn the baby around in time for the birth, and in many cases require an emergency cae-sarean section.M)This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome(SARS)and ultimately, even bigger than AIDS.（分数：20.00）(1).The predictive test will he

42、consumers, a fact not lost on marketers and advertisers. Green advertising started in the mid-1980s when issues of the environment muscled their way to the forefront of marketing. Advertisers saw the consumer desire for environmentally safe products and tried to meet the demand as quickly as possibl

43、e. Not surprisingly, this first wave suffered from rough and poorly conceived marketing efforts. Many advertisers embraced a genuine concern for the environment. But consumers realized that some companies made false claims and exploited the movement, using such nebulous(模糊的)terms as “environmentally

44、 friendly“ and “green.“ Consumers grew wary of environmental appeals, and advertisers reacted by reducing its emphasis. To avoid future trouble, many companies waited for state and federal governments to define terms and provide legal guidelines, which paved the road to a second wave. In 1992 the Fe

45、deral Trade Commission established guidelines for green marketing, followed shortly by state governments. California passed particularly strict laws, setting definitions for terms like “ozone friendly,“ “biodegradable,“ and “recycled.“According to the states court, “California seeks to guard against potentially specious: claims or ecological puffery(吹捧)about products with minimal environmental attributes. “Texas, Massachusetts, Minnesota, Tennessee, Connecticut, and Washington soon followed the Golden State s lead. The rigid regulations ha
