Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons in our brains. Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it,whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions they also tell us that there is a biological basis for the way we understand other people. Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: "The hand took hold of the ball"), the same mirror neurons were as when the action was actually performed (in this example, actually taking hold of a ball). Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders. Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact .Indeed, it may turn out to be the equivalent for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does---well, perhaps you'll understand why. Mirror neurons can explain _ . A) why we cry when we are hurt B) why we cough when we suffer from a cold C) why we smile when we see someone else smile D) why we yawn when we see someone else stay up late

Q: Fred Michel is one of 7.2 million Americans who moonlight. Once a week, after his day job as medical director of a mental health center, the 40-year-old psychiatrist heads to a part-time job at a treatment center for young people. Twice a month, he travels three hours to another teenage treatment center. Last year, 5.4 percent of the American workforce held second jobs, according to the US Labor Department, and that looks set to increase this year. Many workers like the safety that moonlighting provides, says Carl Hausamn, the writer of "Moonlighting: 148 Great Ways to Make Money to the Side". The information from the US Labor Department shows that 40 percent of US moonlighters in 1997 took a second job to meet household expenses or pay off debts. Others save money or buy some special things. People also take second jobs with an eye to the future--wanting to try out a new field or gain experience. Michel started moonlighting when medical systems were unstable . He wanted to make sure he wasn't tied to one system that ended up failing. Just as the purposes for moonlighting are different, the moonlighters cross all age and racial groups. And they work in a variety of industries---no longer just service,office and sales jobs. As its name means, moonlighting still occurs mostly at night. And that results in some pressures. Chief among them is time. Full-time employers could misunderstand, too. Some companies do not allow after-hour work because they fear it will affect their employees' 9-to-5 performance. "The primary employer is saying, 'Wait, I'm paying you for the sharp, fresh, energetic you,'" says Tom Gimbel, president and founder of LaSalle Staffing in Chicago. "If you're burning yourself at both ends, it's going to show." Still, the good done to the moonlighters can be great. Besides extra income, moonlighters enjoy variety , freedom and chance to do something new. They also may find their part-time jobs strengthen what they do full time. Besides, "it's fun," Michel says. Not only do his... What is the closest definition of "moonlight"? A) Go out at night. B) Do some secret things at night. C) Go out for a walk at night. D) Take some part-time jobs at night.
A: D
*Question*
CHICAGO --Bill Clinton's eagerly awaited memoir , My Life, will be published this June, and is sure to ignite a firestorm of interest in an already politically charged election year. Bill Clinton said that most presidential memoirs are thought to be "dull and self-serving, but I hope mine is interesting and self-serving." My Life, which is being published by Knopf and will sell for $ 35, is expected by many industry watchers to rise to the top of the best-seller lists. Clinton said the book tells the story of his life from his birth and childhood in Arkansas to his years in the White House. From the book readers can have a look at his successes and _ . He tells the story "as it happens to me, so you see what it's like to be president ... to see how everything happens at once." Without offering specifics or mentioning Monica Lewinsky, Clinton said, "I don't spare myself" in the book. "I have no idea if this is a great book," he said, "but it's a pretty good story. " Clinton was reportedly paid an advance of $10 million for the book, which was supposed to be done a year ago. "The minute that book goes on sale, people will be lined up buying the book," said Bob Wietrak, a vice-president and chief merchant for Barnes & Noble. Some predict the 957-page book will be one of the few presidential memoirs to fly off shelves. Booksellers have already taken pre-orders. The 1.5 million-copy first printing is bigger than the first run for Hillary Clinton's memoir Living History, which sold 1.8 million copies. Readers will not find much information about _ in the book. A) Clinton's childhood B) Clinton's affair with Monica Lewinsky C) Clinton's political life D) Clinton's presidential election
