单选题{{B}}TEXT D{{/B}} Stress is a word commonly found in today's vocabulary, and is often used to describe modern working and living patterns, especially in big cities. Yet stress has been a part of daily life since time immemorial. Thus it would be more pertinent to define stress as the way in which the human body deals with all kinds of threatening situations, from confrontations with wild, vicious animals, to struggling through a crowded subway station during the early-morning rush hour: the effects on the body being universal. When confronted with a stressful situation the body reacts by releasing a hormone known as ACTH from the posterior pituitary gland situated at the base of the brain. The hormone, traveling through the network of arteries that make up the primary blood supply route, reaches the kidneys, or more specifically, glands situated on the peripheries, where it stimulates the release of adrenaline. This has an antagonistic effect on various bodily functions. That is to say it stimulates a response in certain organs, whilst inhibiting action in others. In other words a type of trade-off is reached, whereby energy saved by shutting down one function is thus used to enhance the performance of a neighbor. In this way, the body can prepare itself fully for the oncoming danger by using, primarily, the same given amount of energy, giving rise to what is known as the fight or flight response. When the fight or flight response is activated, with the release of adrenaline, blood is directed away from non-vital functions such as the skin and digestion, and redirected to the essential organs such as the brain to facilitate thought, the large muscle groups to facilitate speed, and the lungs to increase the amount of oxygen uptake into the bloodstream, whilst the heart beats faster to pump the blood round the body at an increased rate of speed, and raising the blood pressure. Once the stressful situation has passed the opposite occurs, resulting in what is known as the sympathetic rebound. The heart slows down and blood is redirected away from the lungs, brain and muscles, flowing, once more, to every part of the body, whilst digestion resumes. It is, however, the sympathetic rebound, or more specifically, the effects of the sympathetic rebound that lead to the myriad of modern stress-related diseases. Stress, in fact, has been linked to many more common diseases, such as cancer and even the common cold. The reason for this is that during the fight or flight response the body's immune system that fights disease is also shut down, leaving the person more vulnerable to illness, and is, indeed, one of the commonest forms of stress-related problems. Unfortunately, however, modern life is packed full of stressful situations, and costs industry, thus the economy, millions of dollars each year in lost revenue. Traveling to work in the morning, meeting tight deadlines whilst at work, studying to further one's qualifications, paying the mortgage or children's school fees are but a few. Thus, it transpires that stress is a modern day epidemic that urgently needs addressing.

单选题"As a practical matter he had no past only a future. That"s when he really came alive when you got him on the subject of what was going to happen next." So writes Michael Lewis of Jim Clark in his new bestseller The New New Thing about the people in the place of the future Silicon Valley. The new new thing--it"s the thing to do these days: come up with an idea, start an Internet company and get filthy rich. Even though Yale University junior Joshua Newman doesn"t quite have Clark"s billions, Lewis could have been writing about Newman. This Internet wonder kid has already launched two start-ups and he, like Clark, comes alive when you get him talking about the possibilities of the future. Newman grew up in Palo Alto C. A., the Internet Mecca of the world, but he entered Yale with no business experience and certainly no intention of someday starting his own company. "If you told my parents then that I"d be doing something like this," Newman says, "there would have been mild shock and incredulity." It was during his freshman year at Yale that Newman met David Fischer, then a junior and the two of them began playing around with the idea of starting their own business. Newman"s first start up with Fischer was Sharkbyte, an Internet strategy and consulting site that was recently acquired by Quantrum International. While others hit Wall Street or Capitol Hill for fancy summer internships, Newman devoted his past two summers to working feverishly to hit the Internet jackpot--and he plans to spend this upcoming summer launching his newest company Paradigm Blue, a venture capital site dealing with student-driven projects. During the school year Newman has the typical college student"s challenge of juggling school and play. But in Newman"s case play is running his company, meeting prospective clients and driving to New York City several times a week. How many hours a week during the school year does Newman devote to his non-academic work? Newman does not keep count he"s too afraid of the figure that he"d come up with. During the summer months Newman did extensive traveling, meeting with potential clients all over the country. He has employed several college students in his company. The summer has become a popular time for students to get their feet wet in the business and Newman has taken advantage of that. For now, Newman is focused on launching Paradigm Blue. His goal is for the site to raise $10 million by May 1 st at which time he and his partners will close the fund and start their fun. What comes next who knows? But that"s what"s so fun about the new new thing.
