For many people, the ideal way to do homework involves listening to music. But some parents disagree, saying: “Switch off the music and concentrate!”
Well, if that’s the case with your parents, you might now be able to convince them that you have science on your side.
A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy(准确性) and speed, the Telegraph reported.
The company gave 26 participants a series of different tasks for five days in a row, including spell checking, equation (方程式) solving, and mathematical word problems. The participants completed these tasks while listening to one of four music genres (类型), or no music at all. The results showed that while music was playing, 88 percent of participants produced their most accurate test results and 81 percent completed their fastest work.
“The message is that music is a very powerful management tool to increase not only the efficiency of workforce but also your emotional state.” said David Lewis, chairman of Mindlab International.
However, not all genres match all homework. For mathematics, or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. Previous studies had said that listening to Mozart makes a person smarter, and now that conclusion has gained more support. And if you need to finish a paper very soon, say, in an hour, the study said that listening to some pop music might be helpful.
In the study, pop music enabled participants to complete their tasks 58 percent faster than when listening to no music at all. If you’re reviewing your English writing, pop music is also the best choice, as it is the best genre for spell checking. It cut mistakes by 14 percent, compared to listening to no music.
And to check your homework, you should probably listen to some dance music, as this genre resulted in the highest overall accuracy and fastest performance across a range of tasks in the study. In other words, it fits all subjects.
1.According to David Lewis, listening to music while working ______.
A. improves efficiency and mental state B. increases people’s creativity
C. makes people more emotional D. distracts people’s attention
2.Which of the following helps you review English words faster and more correctly, according to the article?

Britain's most popular lie has been disclosed, with one in four people admitting using “sorry I had no signal" when returning a missed mobile phone call, a survey found.
Researchers found the average Briton tells on average four lies every day or almost 1500 every year. Almost one in six men admitted they were most likely to lie to their wife or girlfriend, on average at least twice a day. The most popular lie was saying you had no mobile phone signal, with one in four people admitting regularly using the little white lie. It usually came after they hit the “ignore" button when their mobile rang.
Three quarters of people think women are better liars. The research found 46 per cent of girls have been caught lying, compared to 58 of men.
The second most common fib（无关紧要的谎言） is “I haven't got any cash on me” when asked for money by tramps (流浪者), beggars and Big Issue sellers. “Nothing's wrong – I'm fine” came third followed by “You look lovely” and “Nice to see you”.
Modern technology turned out to have contributed to many lies with “I didn't get your text” in 18th, “Our server was down” in 20th and “My battery died” in 26th place. Other lies to make the top ten included “I'll give you a ring”, “We're just good friends” and “We'll have to meet up soon”. “I'm on my way” and “No, your bum doesn't look big in that” completed the top ten.
Men tell the most fibs, coming out with five every day compared to women who lie just three times.
In many cases perhaps it is better to flatter with a fib than destroy someone with the truth, according to a spokesman for OnePoll, which carried out the research of 4,300 adults.
1.Whether the person being called has pushed the “ignore” button or ______, the caller at the other end hears the same tone.
A. really has no signal B. can’t get the text
C. has a battery failure D. answers the call
2.Most people think women are better liars because ______.
A. there’re more women liars B. fewer women liars are found out
C. women tell less harmful lies D. women are harder to convince
3.“You look lovely” and “I’m on my way” rank _____ on the popular-lie list.
A. 3rd and 8th B. 5th and 10th
C. 4th and 9th D. 5th and 12th
4.The OnePoll spokesman seems to think it’s ______ for the British to lie so much.
A. puzzling B. unpleasant
C. impossible D. reasonable
Preventing obesity and smoking can save lives, but it doesn’t save money, reported researchers. “It was a small surprise, for it is against the common belief,” said Pieter Van Baal, who led the study. “But it makes sense. If you live longer, then you cost the health system more.”
The researchers found that from age 20 to 56, obese people racked up (累计) the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than healthy people. Therefore in the long run, the thin and healthy group cost about $417, 000, from age 20 on. Smokers cost about $326, 000 and obese people $371, 000.
“The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars,” said Patrick Basham, a professor of health politics. “If we’re going to worry about the future of obesity, we should stop worrying about its financial impact,” he said.
“The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrow’s budget, but there are long-term gains,” said Van Baal. “These are often immeasurable when it comes to people living longer and healthier lives.” In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life.
“Lung cancer is a cheap disease to treat because people don’t survive very long. But if they are old enough to get Alzheimer’s (早老性痴呆症) one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity,” Van Baal said. “But they should do it for the right reasons.”
1.Among middle-aged people, who may cost the health system most?
A. Those who are heavy smokers. B. Those who are overweight.
C. Those who are too thin. D. Those who are suffering from heart attacks.
2.What can we know about the belief that obesity costs much?
A. It turns out to be incorrect. B. It comes from scientific study.
C. It is based on medical evidence. D. It has changed over the past years.
3.According to the text, governments prevent obesity for the purpose of _______.
A. reducing the risks of suffering cancer
B. weakening obesity’s financial impact
C. making sure of people’s long and healthy life
D. reducing the money spent on medical programs
