当喝酒的“老习惯”与驾车的“新方式”遭遇的时候，有的人想“鱼与熊掌兼得”，既喝酒又驾车。因此，如果不从社会传统和社会心理的角度，对刚刚走进汽车社会的人们进行引导教育，而只靠疾风暴雨的执法运动，很难根治酒后驾车的顽疾。当然，我们也看到，随着社会舆论的深入讨论和专项行动的持续展开，“喝酒不驾车，驾车不喝酒”的基本理念正在逐步深入人们的生活。
这段文字的主要观点是( )。
A．根治酒后驾车顽疾不一定要开展专项行动
B．社会习惯的转变往往需要一个漫长的过程
C．转变生活理念是解决酒后驾车问题的根本途径
D．专项行动对于解决酒后驾车问题治标不治本
参考答案：C
解析： 作者首先提出人们存在既想喝酒又想驾车的生活理念，接着指出，如果不从社会传统和社会心理的角度进行引导，仅靠专项执法运动很难根治酒驾问题，最后补充说明我们在引导人们正确对待喝酒与驾车的理念方面取得的初步成绩。由此可见，作者主要沦述的是转变生活理念对根治酒驾问题的重要性。故答案选C。
| Ever since it was claimed that a medicine made from the Chinese three-striped box turtle could cure cancer, demand for the product has increased, making the turtle the most expensive to be found in China’s food markets. Huge sums of money have been made selling the medicine. The turtle -- along with a few other Cuora species -- was once imported into China by the pet trade. Exporters obtained the specimens in the food markets rather than going out to collect them in the wild. Treatment of the turtles prior to reaching the markets resulted in many of them being diseased. Packed tightly into crates, often for journeys of several weeks without food, it is little wonder that many specimens exported to western countries fared poorly when purchased as pets. Throughout the Far East turtles and tortoises have featured in various cultures and certain religions. They have also been used for hundreds of years for food and medicine. Traditional Chinese medicine is probably the greatest threat to the three-striped box and to the thousands of other turtles that are imported yearly into China. Turtles are well known for their longevity, which it is thought will be passed on to those eating them. Turtle blood, bones and shells -- particularly the plastron (ventral part of the shell) -- are thought to have medicinal properties and be able to cure a number of ailments. Turtle eggs are also used for food and medicine. The medicinal value of the turtles is open to question, and it is possible that herbs could produce the same effects. Any beneficial substances from the turtles could also be synthesized chemically, so as to prevent the killing of turtles. The southern part of China has become more prosperous in recent years, and the demand for turtles has increased dramatically. Turtle dishes are served in restaurants and regarded as an expensive delicacy, even a status symbol. As turtle supplies in China dwindled, traders started importing the animals from Vietnam. As a result, many Vietnamese turtles have now disappeared from their haunts in the wild. To satisfy growing demand, importers have now turned to sources farther afield, including Cambodia, Laos, Nepal, India, Bhutan and Indonesia. Since biologists started studying turtles in Chinese food markets, several previously unknown and extremely rare species have been found; some are on Appendix I of CITES. At the present rate of collection such specimens, and even species not yet discovered, could soon be extinct. The three-striped box turtle is simply one among dozens of other species flooding into China, but its high value makes it a special target for collectors. |
