[单项选择]A pioneering study by Donald Appleyard made the surprising discovery that a sudden increase in the volume of traffic through an area affects people in the way that a sudden increase in crime does. Appleyard observed this by finding three blocks of houses in San Francisco that looked much alike and had the same kind of middle-class and working-class residents, with approximately the same ethic mix. The difference was that only 2000 cars a day ran down Octavia Street (LIGHT street in Appleyard’s terminology) while Gough Street (MEDIUM street) had 8 000 cars a day and Franklin Street (HEAVY street) had around 16 000 cars a day.
Franklin Street often had as many cars in an hour as Octavia Street had in a day. Heavy traffic brought with it danger, noise, fumes, and soot, directly, and trash secondarily. That is, the cars didn’t bring in much trash, but when trash accumulated, residents seldom picked it up. The cars, Appleyard determined, reduced the amount of territory residents felt

[单项选择]Dina Borzekowski made a study of a group of third-grade students from six American schools. During a school year, nearly 400 students and their parents were asked to report on whether they had such things as televisions and computers in the home, as well as how often the child used them. The children’s language ability was tested (测验) twice over the year. Children who had a television set in the bedroom but did not have a computer at home scored (得分) the lowest, while students without TV in the bedroom but with a computer at home scored the highest. Students who had a television in the bedroom over the school year scored lower than those who had their TV taken away during the same time.
"This study suggests that taking TV sets out of children’s bedrooms, or not putting them there, may be helpful," said Borzekowski. "While this study does not prove (证明) that bedroom TV was the reason for the lower test scores, it suggests that children shouldn’t have TV in their bedrooms. It also
