[单项选择] I first became aware of the unemployment problem in 1928.

We might not stay as long. We might eat cheese sandwiches," he said.
At Notre Dame Cathedral a few blocks away, Linda Surma from Detroit, Michigan says she is also shocked by high prices in Paris these days. But Surma does not regret deciding to come to Paris, and has no plans to trim tourist attractions from her itinerary because of the expense—even if she might not buy souvenirs.
Paul Roll is managing director of the Paris Convention and Visitors Office. He says American tourists in Paris—who numbered about 1.5 million last year—tend to cut expenses when the dollar is weak, rather than cancel their trip.
