Whether you prefer burning the midnight oil or going to bed early so you can get up at the break of dawn depends on your genes , according to experts. I jump out of bed each morning, eager to start an active day. But I can hear my neighbour's        alarm clock ringing non-stop every morning and I doubt he gets to work on time. A lot of noise comes from his flat in the evening. He's happy to stay up watching TV till after midnight, while I go to bed early and try to sleep. Well, it might not be his fault after all. I'm called 'a lark  ' and my neighbour 'an owl  '. We all have inside 'clocks' in the brain to control all kinds of bodily functions and it is reset every day by light. These inside clocks run to a different schedule in 'larks' and 'owls'. If you have a fast clock, you like to do things early, and if you have a slow clock, you like to do things late. Because we live in a 24/7 world, scientists believe it's important to understand a person's 'chronotype' - the time of the day when they function the best. It could help us lead a healthier life. A US professor has studied sleeping patterns and thinks work times should be changed and made more individual to fit in with our chronotypes. And he has advice for those who can't choose their working hours: "If that's not possible, we should be more careful about light exposure", says the professor. "You should try to go to work not in a covered vehicle but on a bike. The minute the sun sets we should use things that have no blue light, like computer screens and other electronic devices." We can learn from the passage that the author's neighbour   _  . A) almost always gets to work on time B) has to work deep into the night every day C) is passive during the day but energetic at night D) is easily woken up by his alarm clock in the morning

The easiest way for the English to deal with their social discomfort is to avoid social interaction altogether, by choosing either leisure activities that can be performed in the privacy of one's own house, or outdoor activities that follow their interest without direct contact with anyone other than one's own family members, such as going for a walk, or to the cinema, or shopping. In recent survey, over half of all the leisure activities were of this private  _ type, and of the top ten pastimes, only two--having friends round for a meal or drink, and going to the pub--could be described as 'sociable'. The most domestic activities are the most popular: watching TV, listening to the radio, reading, DIY (Do It Yourself) and gardening. Even when the English are being sociable, the survey findings show that most of them would much rather entertain a few close friends or  s in the safety of their own homes than venture out among strangers. In the latest rational census survey  , over half of the entire adult male population had been DIYing in the four weeks before the census date. Nearly a third of the female population had also been busily improving their homes, and their work with their gardens was equally obvious: 52 percent of all English males and 45 percent of females had been out there, cutting branches and weeding grass. Even among people claiming to belong to a particular religion, only two percent attend services every week. The rest of the population can be found every Sunday at their local garden center or DIY superstore. And when they want a break from caring about their own homes and gardens, they go on trips to visit bigger and better houses and gardens, such as the stately homes and gardens opened to the public by the National Trust and the Royal Horticulture Society. Visiting grand country houses always ranks as one of the most popular national pastimes. The result of the survey shows that_. A) about half English people enjoy working in their gardens B) 8 out of 10 pastimes can be described as social activities C) 2 percent of the religious people enjoy visits to public houses D) visiting stately homes is the most popular national pastime

Beautiful people are indeed happier,a new study says,but not always for the same reasons. For handsome men,the extra kicks are more likely to come from economic benefits,like increased wages, while women are more likely to find joy just looking in the mirror. "Women feel that beauty is naturally important," says Daniel Hamermesh,a University of Texas at Austin labor economist and the study's lead author. "They just feel bad if they're ugly." Hamermesh is the acknowledged father of pulchronomics, or the economic study of beauty. It can be a dangerous job. He once made angry an audience of young Mormon  women, many of whom wished to stay home with future children, by explaining that homemakers tend to be less attractive than their working-girl peers . "Since beautiful women tend to be paid more,they have more motivation to stay in the work force," he says. The pursuit of good looks drives several huge industries--in 2010, Americans spent  $845 million on face-lifts alone--but few economists focused on beauty's financial power until the mid-1990s,when Hamermesh and his colleague, Jeff Biddle of Michigan State University, became the first scholars to track the effect of appearance on earnings potential for a large sample  of adults. Like many other desirable commodities , "beauty is rare,"  Hamermesh says, "and that rareness commands a price." A handsome man is estimated to make 13 percent more during his career than a "looks-challenged" peer, according to calculations in Hamermesh's recent book, Beauty Pays. Interestingly, the net benefit is slightly less for pretty women, who may make up the difference by trading on their looks to marry men with higher earning potential. And some studies have shown that attractive people are more likely to be hired in a recession . Hamermesh argues that "there's not much we can do to improve our pulchritude ". There are even studies suggesting that for every dollar spent on cosmetic  products,only 4 cents returns as salary--making lipstick a truly awful investment.  _ . One...
