No organ of the body is less appreciated than the skin, one of our biggest organs--and the most important telltale--it mirrors the state of our health, our age, and our race. Occupation and way of life may also become indelibly imprinted for all to see. Here are some facts about our outer covering organ to show that there is more to the skin than meets the eye.Your skin is your body’s thermostat. It adjusts heat gain and loss so that the internal temperature remains within the normal range of 97 to 99 degrees.It takes about two square yards of skin to cover the average adult from head to toe. Undoubtedly the most intricate wrapping in existence, the skin contains 3 million cells, three feet of blood vessels, and twelve feet of nerves in each area the size of a postage stamp.The widest difference between the darkest human skin and that of an albino is brought about by not more than 1/25 of an ounce of melanin. As far as is known, the amount of this dark brown or black pigment accounts for our variations in racial colors, including yellow, brown, and black. What is the skin（）
It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. Everybody knows that the nicest men become monsters behind the wheel. It is all very well, again, to have a tiger in the tank, but to have one in the driver’s seat is another matter altogether. You might tolerate the odd road-hog, the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a "Be Kind to Other Drivers" campaign, otherwise it may get completely out of hand.Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently to allow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the road would be clear anyway; or the man who waves a child across a zebra crossing into the path of on-coming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to. It always amazes me that the highways are not covered with the dead bodies of these grannies.A veteran driver, whose manners are faultless, told me it would help if motorists learnt to filter correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone master the subtler aspects of roadmanship. Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart. By "good sense" (in Para. 2), the writer means（）
Public officials and candidates for public office routinely use public opinion polls to keep track of what the people are thinking. An important question is the degree to which these polls should guide leaders in their actions. There are arguments for and against the use of polls as the basis for policy decisions.Polls can contribute to effective government by keeping political leaders from getting too far out of line with the public’s thinking. In a democratic society, the effectiveness of a public policy often dep. ends on the extent of its public support. When a policy is contrary to the public’s desires, people may choose to disregard or undermine it, thus making it counterproductive or inefficient. Further, when government pursues a course of action with which a large proportion of the public disagrees, it risks a loss of public confidence, which can have a negative effect on its ability to lead. The Reagan administration, flying high from 1981 to 1985 ,was brought low in 1986 by public reaction to news of its secret sales of weapons to Iran. The administration had not paid sufficient attention to polls that revealed the deep antagonism American still felt toward Iran be cause the Ayatollah Khomeini’s regime has held sixty-three American hostages in 1979 - 1981.However, leaders can also do a disservice to the public they represent by using poll results as a substitute for policy judgment. "Effective government", as Walter Lippmann wrote, "cannot be conducted by legislators and officials who, when a question is presented, ask themselves first and last not what is the truth and which is the right and necessary course, but what does the Gallup Poll say" During his presidential term, Jimmy Carter proposed five consecutive inflation-fighting programs, changing his plans with each shift in public sentiment without having invested the political capital necessary to get Congress and the country behind any of the efforts. The nation -- and Carter -- would probably have been better served by a steadfast commitment to a single course of action. Paragraph 2 mainly implies that（）
