　　英语CET6阅读理解通关练习题及答案 1

　　Which is safer-staying at home， traveling to work on public transport， or working in the office? Surprisingly， each of these carries the same risk， which is very low. However， what about flying compared to working in the chemical industry? Unfortunately， the former is 65 times riskier than the latter! In fact， the accident rate of workers in the chemical industry is less than that of almost any of human activity， and almost as safe as staying at home.

　　The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this which makes chemical accidents so newsworthy. Fortunately， they are extremely rare. The most famous ones happened at Texas City (1947)，Flixborough (1974)， Seveso (1976)， Pemex (1984) and Bhopal (1984)。

　　Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso， and only 28 workers at Flixborough. The worst accident of all was Bhopal， where up to 3，000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives， just a month before the unfortunate event at Bhopal.

　　Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas City explosion was caused by tons of ammonium nitrate(硝酸铵)，which is safe unless stored in great quantity. The Flixborough fireball was the fault of management， which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town， local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in an overcrowded suburb. The fire set off a chain reaction os exploding storage tanks. Yet， by a miracle， the two largest tanks did not explode. Had these caught fire， then 3，000 strong rescue team and fire fighters would all have died.

　　1.Which of the following statements is true?

　　A.Working at the office is safer than staying at home.

　　B.Traverlling to work on public transport is safer than working at the office.

　　C.Staying at home is safer than working in the chemical industry.

　　D.Working in the chemical industry is safer than traveling by air.

　　2.Chemical accidents are usually important enough to be reported as news because ____.

　　A.they are very rare

　　B.they often cause loss of life

　　C.they always occur in big cities

　　D.they arouse the interest of all the readers

　　3.According to passage， the chemical accident that caused by the fault of management happened at ____.

　　A.Texas city B.Flixborough C.Seveso D.Mexico City

　　4.From the passage we know that ammonium nitrate is a kind of ____.

　　A.natural gas， which can easily catch fire

　　B.fertilizer， which cant be stored in a great quantity

　　C.poisonous substance， which cant be used in overcrowded areas

　　D.fuel， which is stored in large tanks

　　5.From the discussion among some experts we may coclude that ____.

　　A.to avoid any accidents we should not repair the facilities in chemical industry

　　B.the local authorities should not be concerned with the production of the chemical industry

　　C.all these accidents could have been avoided or controlled if effective measure had been taken

　　D.natural gas stored in very large tanks is always safe

　　答案：DBABC

　　英语CET6阅读理解通关练习题及答案 2

　　A: How does one define when a 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 weight. The "Body Mass Index" (BMI) is calculated by dividing the persons 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 over 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 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 terms of waist circumference.

　　Health Effects of Obesity

　　D: 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, social 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 obesity and coronary heart disease is also well-known.

　　Cancer

　　E: 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 5,893 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 status 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 could 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 newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!

　　Aging

　　H: 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 womans biological 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 woman’s biological age, and although the study only involved women, 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 "chromosomal 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 body 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 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 Institute 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 enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia.

　　Other Problems

　　L: The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research 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 obese—a growing proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.

　　M: This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.

　　1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.

　　2. Using the "Body Mass Index"to define a persons weight ideal is limited, because it does not takes into account many variables such as age, gender and ethnic origin.

　　3. A persons emotional well-being would be affected by obesity.

　　4. Obesity has something to do with cancer in the prostate gland for man.

　　5. Women from less affluent nations tend to have much less breast cancer.

　　6. A non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to her biological age.

　　7. The excess body fat, like the chemicals present in tobacco smoke, can lead to inflammation.

　　8. Obese people in middle age run an increased risk of dementia .

　　9. The predictive test for dementia will help people to affect lifestyle changes that will reduce their risk of contracting dementia.

　　10. The world-wide upsurge in obesity, particularly in children, will possibly drain economies.

　　英语CET6阅读理解通关练习题及答案 3

　　Faced with rapid change and the fear anduncertainty1 that go with it, individuals as well asnations sometimes seek to return to the ways of thepast as a solution. in the early 1980s the idea ofreturning to the ways of the past had a strongappeal 2 to many americans who increasingly viewedtheir past as being better than their future. Twofamous experts have observed that until the 1970 s americans generally believed that thepresent was a better time for their country than the past and that the future would be betterthan the present; by 1978, however, public opinion polls3 showed that many americans hadcome to believe that just the opposite 4 was true: the past had been better for the countrythan the present, and the present was better than the future would be.

　　The popular appeal of returning to the ways of the past as a solution to the problems of the1980s was demonstrated when ronald reagan5 was elected president of the united states in1980 . time magazine chose president reagan as its "man of the year" and said of him, "intellectually, emotionally, reagan lives in the past."

　　One of president reagan’s basic beliefs is that the united states should return as much aspossible to its pre-19307 ways. in those times business institutions were strong andgovernment institutions were weak. reagan believes that the american values of individualfreedom and competition are strengthened by business and weakened by government.therefore, his programs as president have been designed to greatly strengthen business andreduce the size and power of the national government. by moving in this way toward thepractices of the past, president reagan believed that the standard of living of americans wouldbegin to improve once more in the 1980s as it had done throughout most of the nation’shistory.
