材料：The Official SAT Study Guide

试卷：3

页数：569

题号：14

Questions 11-20 are based on the following passage and supplementary material. This passage is adapted from Taras Grescoe, Straphanger: Saving Our Cities and Ourselves from the Automobile. ©2012 by Taras Grescoe.

It doesn’t have to be like this. Done right, public transport can be faster, more comfortable, and cheaper than the private automobile. In Shanghai, German-made magnetic levitation trains skim over elevated tracks at 266 miles an hour, whisking people to the airport at a third of the speed of sound. In provincial French towns, electric-powered streetcars run silently on rubber tires, sliding through narrow streets along a single guide rail set into cobblestones. From Spain to Sweden, Wi-Fi equipped high-speed trains seamlessly connect with highly ramified metro networks, allowing commuters to work on laptops as they prepare for same-day meetings in once distant capital cities. In Latin America, China, and India, working people board fast-loading buses that move like subway trains along dedicated busways, leaving the sedans and SUVs of the rich mired in dawn-to-dusk traffic jams. And some cities have transformed their streets into cycle-path freeways, making giant strides in public health and safety and the sheer livability of their neighborhoods—in the process turning the workaday bicycle into a viable form of mass transit.

14. The central idea of the fourth paragraph (lines 35-57) is that

A) European countries excel at public transportation.

B) some public transportation systems are superior to travel by private automobile.

C) Americans should mimic foreign public transportation systems when possible.

D) much international public transportation is engineered for passengers to work while on board.

答案：B

答案解析： 本题问的是第四段 (lines 35-57) 的中心思想。根据中心题的解答技巧，我们要特别关注段落开头和结尾。本段开头提到 “It doesn’t have to be like this.” 显然是对上文内容的否定，然后lines 35-37开门见的指出 “Done right, public transport can be faster, more comfortable, and cheaper than the private automobile.” 即：使用正确的话，公共交通比私家汽车更快、更舒适、更便宜，后面给出了很多例子来支撑这个观点。因此，答案为B选项。

A、B、C选项的错误都在于仅提供了细节信息，并不能涵盖本段的中心思想。
