第8题

Park and Burgess based their model of urban growth on the concept of "natural areas"—that

is, areas such as occupational suburbs or residential enclaves in which the population is relatively homogeneous and land is used in similar ways without deliberate planning. Park and Burgess saw urban expansion as occurring through a series of "invasions" of successive zones or areas surrounding the center of the city. For example, people from rural areas and other societies "invaded" areas where housing was inexpensive. Those areas tended to be close to the places where they worked. In turn, people who could afford better housing and the cost of commuting "invaded" areas farther from the business district.

According to paragraph 4, why is the term "Loop" used in the concentric-zone model？

A．It indicates the many connections between each of the zones in the model.

B．It indicates that zones are often in transition and frequently changing.

C．It reflects the fact that the model was created with the city of Chicago in mind.

D．It emphasizes the fact that populations often returned to zones in which they used to live.

听力原文：Original or Extra Crispy, not exactly health fare, but it will soon be healthier

at KFC.Fried in a better for you zero trans fat soybean oil. Colonel Sanders would be very proud of us today. He's probably smiling down on us because we've found a solution that preserves all the finger licking good taste of KFC's chicken but now with zero trans fat. The announcement came just hours before a New York City Board of Health hearing. New York wants to be the first US city to ban restaurants from serving food containing trans fat. Health advocates say fast food needs to be reined in by lawmakers. If we don't act now, generations after us will wonder why we sat back and watched the diabetes and obesity epidemics and the poor health outcomes that come with them spread through our city. Trans fat is so common that the FDA says most Americans eat 4.7 pounds of it a year. Health experts say contributing to obesity and clogged arteries. Consumer demand for more healthy fast food has led some burger chains like Wendy's to transition to zero trans fat oil. But some consumers wonder if the switch means losing flavor. I don't believe the taste is still gonna be the same. OK KFC says the lawsuit did not prompt the change. The transition should be complete by April of next year. Still containing trans fats though, KFC's biscuits.

Who is Colonel Sanders？

A．The founder of KFC.

B．The president of KFC.

C．The general manager of KFC.

D．A customer of KFC.
