单选题 Around the world, the bicycle is a favorite method of transportation, especially
Line in China. With its large urban population, China ranks first in the world in
bicycle production and use. In fact, China is responsible for half of the world's
bike ownership, with 10 million bicycles found in Beijing alone. This amounts
(5) to about one bicycle for every two residents, and makes cycling the most popular
form of transportation in the capital.
However, as economic prosperity has increased, individual car ownership
has also risen. This shift has contributed to already serious problems with urban
pollution and traffic congestion. As a result, the government has encouraged even
(10) more bicycle use. Bike lanes have been added to city streets, and more bicycle
parking lots have been created throughout Beijing. Still, critics point out that cars
are much more convenient for many daily activities in a large city. Only time will
tell if government measures will ensure that bicycles remain the favorite method
of transportation.

单选题 The author of the passage is primarily concerned with

A、 promoting the use of bicycles in urban areas
B、 documenting the rise of car ownership in modern China
C、 illustrating the importance of bike lanes in promoting bicycle usage
D、 describing the various sources of air pollution in modern China
E、 (E) describing the importance of bicycles for transportation in urban China

【正确答案】 E

【答案解析】Answer choices B, D, and C are all mentioned in the passage, but only as details supporting the main idea, which is the importance of bicycle use for transportation in urban China. Answer choice A is insufficiently specific because it doesn't mention China. Also, the author describes only a situation; she does not promote, or advocate, any particular program.

单选题 The author implies that car ownership in China is on the rise because

A、 bicycles are seen as old-fashioned
B、 Beijing air pollution makes cycling too difficult
C、 there are now more wealthy Chinese able to purchase cars
D、 bicycles are easier to maneuver on busy streets
E、 (E) government measures to increase bicycle use have been largely unsuccessful

【正确答案】 C

【答案解析】The author addresses rising car ownership at the beginning of the second paragraph. Increased economic prosperity implies there is more money available and, consequently, more wealthy Chinese to purchase automobiles. Answer choices A and E are not addressed by the passage. Answer choice D is contradicted by the passage. While answer choice B is a plausible assumption, there is not enough evidence in the passage for it to be a credited answer.
