问答题Practice 2 Directions: Read the following text(s) and write an essay to 1) summarize the main points of the text(s), 2) make clear your own viewpoint, and 3) justify your stand. In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks (“ ”). You should write 160—200 words on the ANSWER SHEET. It is all very well to blame traffic congestion, the cost of petrol and the hectic pace of modern lift, but manners on the roads are becoming deplorable. Everybody knows that 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 drivers seat is completely another awkward and difficult situation. You might tolerate the odd mad hog, 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 courtesy is not only good manners, but good sense too. It takes the most levelheaded and good-tempered of drivers to resist the temptation to retaliate when subjected to uncivilized behavior. On the other hand, a little courtesy goes a long way towards relieving the tensions and frustrations of motoring. A friendly nod or a wave of acknowledgement in response to an act of courtesy helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such acknowledgements of courtesy are all too rare today. Many drivers nowadays don't even seem able to recognize courtesy when they see it. Lorry drivers say they have almost abandoned the practice of signaling cars to overtake when the road is clear, because many of the cars took too long to pass. Their drivers couldn't be bothered to select a lower gear. Others, after overtaking, slowed down again and hogged the road. They manufacture them by force, using their direction indicators as a threat rather than a warning. Slanting matches and even punch-ups（打架斗殴）are quite common. It can't be long before we hear of pistols and knives being used: we can then call our dual carriageways, and solve a spelling problem in the process. Driving is essentially a state of mind. However technically skilled a driver may be, he can't be all advanced motorist if he is always arrogant and aggressive.
