8、seriously hamper reaction times and cause accidents, new research suggests. A Canadian study found people took up to 20% longer to perform physical and mental tasks to loud music. If motorists were delayed that long at the wheel they could suffer a fatal crash, warned the RAC Foundation, a British m

9、otoring organization. Edmund King, the RAC Foundations executive director, said the study showed that “not only is loud music a nuisance to other,it could also be the cause of accidents“. Earlier research by the RAC Foundation found drivers were twice as likely to skip a red light while listening to

10、 music. In the Canadian study volunteers carried out tasks while listening to levels of noise varying from 53 decibels ( equivalent to an office environment) to 95 decibels (equivalent to an oil rig). Researchers found reactions to be significantly decreased at higher noise levels for both physical

11、and mental work. At 95 decibels reaction times to tasks that involve decision making plummeted(骤然减少 ) by 20%.Edmund King said: “The findings of the Canadian study are bad news for decibel-loving drivers, as they prove that not only is loud music a nuisance to others, it could also be the cause of ac

12、cidents on the roads. “Drivers are at even greater risk if they listen to music with a pounding beat rather than more relaxed tunes, according to experts. Conrad King, consultant psychologist to the foundation, said: “ It is important that drivers choose their music carefully when driving,as up-temp

13、o music has been shown to cause drivers to have double the amount of accidents as those listening to slower music. “In general,if music is a-bove 60 beats per minute, listeners experience a faster rate and increased blood pressure. “It doesnt matter if you listen to opera, classical or the latest ra

14、ve music. Its the speed of the beat that counts. “ 16 According to scientific research, people may spend more time doing physical work if listening to loud music while doing the task. （ A） Right （ B） Wrong （ C） Not mentioned 17 Edmund King believes that loud music will do no harm to drivers. （ A） Ri

15、ght （ B） Wrong （ C） Not mentioned 18 Besides car accidents, loud music may also cause heart attack. （ A） Right （ B） Wrong （ C） Not mentioned 19 At 95 decibels, peoples reaction to decision making decreased by 53%. （ A） Right （ B） Wrong （ C） Not mentioned 20 Listening to the Jazz music can help drive

18、 in a small room called a“calorimeter“ (热量测量室 ) is one way to find out. 1.The signs above the two rooms read simply “Chamber One“and “Chamber Two“.

20、who, over the past eight months, have spent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness programme. As a self-employed communitydance worker, she was able to fit the experiment in ar

21、ound her work. She saw an advert for volunteers at her local gym and as she is interested in the whole area of diet and exercise, she thought she would help out. 3.The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence was repeated four

22、 times over six weeks. She arrived at the calorimeter at 8: 30 am on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine, timed to the last second. At regular intervals, after eating, she filled in fo

23、rms about how hungry she felt and samples were taken for analysis. 4.The scientists help volunteers impose a kind of order on the long days they face in the room. “The first time, I only took one video and a book, but it was OK because I watched TV the rest of the time,“ says Nicola. And twice a day

24、 she used the exercise bike. She pedaled (踩踏板 ) for half an hour, watched by researchers to make sure she didnt go too fast. 5.It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel ful

Most of the energy on Earth comes from the Sun. In fact enough energy from the Sun h

48、its the planets surface each minute to cover our needs for an entire year, we just need to find an efficient way to use it. So far the energy in oil has been cheaper and easier to get at.

49、d most energy needs until the steam-driven industrial revolution, when energy-dense coal became the fuel of choice. Coal is still used, mostly in power stations, to cover one quarter of our energy needs, but its use has been declining since we started pumping up oil.
