单选题 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. You might tolerate the rode 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. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behaviors. 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, improper politeness can also be dangerous. A typical example is the driver who waves a child across a crossing into the path of oncoming 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.
A veteran driver, whose manners are faultless, told me it would help if motorists learn to filter correctly into traffic streams one at a time without causing the total blockages (堵塞) that give rise to bad temper. Unfortunately, modern motorists can not even learn to drive, let alone be well-mannered on the road. 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.

单选题 According to this passage, troubles on the road are primarily caused by ______.

【正确答案】 D

【答案解析】[解析] 该题答案见第一段：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.这句话的含义是：造成交通问题也许有客观原因，但主观原因也很重要。句子通过使用转折词but引出了作者就本文要谈论的问题“司机的驾驶行为”，故选项D正确。

单选题 The sentence "You might tolerate the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule" implies that ______.

【正确答案】 C

【答案解析】[解析] 这里需要注意的问题是：①选项中constitute意为“组成，构成”，如the 50 states that constitute the USA(组成美国的50个州)；②正确理解句子的确切含义，弄清两个并列句间的转折关系，前半句中的tolerate(忍受，容忍)、inconsiderate(不体贴的，不周到的)，后半句中的关键词为exception(例外，除外)，如an exception to the rule(该规则的一个例外)，此处句中的the rule指的是司机礼貌行车的规则，故选项C正确。

单选题 By "good sense" (Paragraph 2), the writer means ______.

【正确答案】 D

【答案解析】[解析] 答案见第二段第一句：Road politeness is not only good manners, but good sense.此句起承上启下的作用，上半句总结了第一段所谈的内容，下半句提出本段要说明的内容。所以理解good sense的线索见整个第二段。从字面意思来看，sense意为“明智，见识，常识”，如He had the good sense to go by train rather than drive after hearing the forecast of icy conditions.(听到天气预报有霜冻结冰的情况后，他明智地决定坐火车去而不开车去。)故选项D正确。

单选题 Experts have long pointed out that in the face of car-ownership explosion, ______.

【正确答案】 A

【答案解析】[解析] 答案见第四段：Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users.(数年前专家警告我们说，拥有车的人数剧增要求所有道路的使用者学会互相谦让。)car-ownership explosion意为“拥有汽车的人多到了极限”；give-and-take为复合名词，意为“互相迁就，互相让步”，其义与选项A中的yield相一致，另如There has to be a lot of give-and-take in any successful marriage.(任何成功的婚姻都要互相忍让。)故A项正确。
