The average British women’s waistline(腰围) has grown by 2 inches in 10 years, all thanks to the sedentary(久坐的) lifestyle.
A study conducted by Cancer Research
Men are also nowhere behind the fairer sex, for the research found that the average man’s waistline has grown by 1.4 inches to 38 inches.
“We know high body weight increases the risk of a number of cancers and it is important we get this message out to as many people as possible,” the Daily Mail quoted Dr Lesley Walker, of Cancer Research
“A healthy diet with plenty of fiber, fruit and vegetables, as well as regular exercise can help people lose weight and reduce their risk of cancer,” he added.
The trend was found to be obvious in the under 45s, where the proportion of men with a body mass index(指数) over 35, and of women with a BMI of over 40, has grown twice during the decade.
Lead researcher Professor Jane Wardle said it is possible that young people follow a less healthy lifestyle than their elders.
“Snacking habits, takeaway meals high in fat and sedentary lifestyles where many people spend both work and leisure time sitting in front of a computer are all likely to contribute to the results.”
She added that genetics(遗传) also play an important role in the growing rate of getting fat.

46. Man’s average waistline used to be ______.
A. 31.8 inches B. 33.5 inches C. 36.6 inches D. 38 inches

A. British women’s waistlines have grown
B. It is easy for the English to get fat

How good are U.S. drivers?
The CBS TV “National Drivers Test” showed that many U.S. drivers have a lot to learn. Here’s why:
CBS picked 1,799 samples(被实验者) to take the test in TV studios in New York, Philadelphia, Chicago, and Los Angeles. More than two out of five of the drivers failed the test. And the average score was the lowest passing mark-51 points out of a possible 80.
Chicago drivers did best with an average of 53 points. Los Angeles drivers came next with 52 points. New York and Philadephia drivers tied(得同样的分数) with 50 points-a failing score. Drivers with 50 points or less were rated(被评价为) “poorly informed” by the judges.
Here are some of the test results:
(1) Are men better informed drivers than women?-Yes. Men averaged 52 points. Women got average of 49.
(2) Are older drivers better informed than younger drivers?-No. Drivers under 26 averaged 52 points. Drivers from 27 to 45 averaged 51. Driver over 45 failed with 48 points on average.
(3) Does education make a difference?-Yes. College graduates averaged 52 points. High school graduates averaged 50. Those without high school diplomas(文凭) got 48. And people who had taken driver education courses scored an average of 53 points-three more than those who hadn’t.
(4) Does driving experience make a difference?-Yes. Drivers with three or more years’ experience averaged 51 points. Drivers with less experience averaged 49.
Here are some surprising facts brought out by the test:
(1)More than one out of three drivers did not know that a blinking(闪烁) red light means a full stop. (2)Three out of ten drivers did not know that an octagonal (eight-sided) sign means stop.
(3)More than two of three drivers did not know what to do when being “tailgated”(危险地,紧接另一辆驶) The answer: slow down, drive to the right, and let the driver behind pass.
The results of the test were turned over to the National Safety Council. They will help future safety planning.

There are two methods by which hydrogen (氢) can be used to power cars. The first way is to use hydrogen to drive the engine, in much the same way as many cars use gas. The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one.
The dream of producing hydrogen in the car while driving along by electrolyzing(电解)water is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas. This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.
Indeed, some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in America and so has Renault in France.
However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen fuel cell car in 1999. They are now producing second generation hydrogen car known as the FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.
Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the world is prepared for them by then.
Then there are hydrogen-powered buses in several European cities including Amsterdam, Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis, have announced that they propose to manufacture hydrogen-powered taxis in time for the London Olympics.
So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses go back to their bus station, where an electrolyzing machine changes water into fuel for them to fill up on and the same will be the case for many of London’s taxis.
Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these vehicles cost about $300,000 each.
1.According to the text, hydrogen-powered buses ________.
A.can easily be filled up with gas. |
B.are likely to sell well in the future. |
C.are mainly used in the United States |
D.won’t be used in the London Olympics |
2.What does the underlined word “them” in paragraph 5 refer to?
A.Japanese companies |
B.Hydrogen buses |
C.The FCX Clarity |
D.Filling stations |
3.Where are hydrogen cars currently available for sale?
A.In Barcelona |
B.In Hamburg |
C.In London |
D.In Los Angeles |
4.We can learn from the text that ________.
A.there are sixty hydrogen filling stations all over the world |
B.hydrogen vehicles fueled by water will be very expensive |
C.Honda will mass-produce the FCX Clarity by 2012 |
D.Honda produced its first hydrogen car in 1989 |
