单选题Chicago is known as the Second City, but for drama (戏剧) it's first-rate. The city has over a hundred professional theatres, where you can see many of America's new writers and actors. With its huge eastern European and Mediterranean populations, Chicago is the place for food from the Old World. For German cuisine (菜肴), try Berghoff, located in the Loop which is the business and financial district. If you like Greek food, go to Greek Islands or one of the other eateries in Greek town, just west of the Loop. If you want a great view and a meal to match, reserve a window table at the 40th floor Everest Room in the Loop. Chicago is best seen on foot. You may check out the shops on North Michigan Avenue, and take an early morning walk in the parks along Lake Shore Drive. In the summer, you may want to join Chicagoans in a swim in the lake. A word on the weather-the city's famous winds can cause extreme changes in temperature. Even in the summer there can be 30-degree differences—it can be 90 degrees one day and 60 degrees the next. So you might as well bring a sweater.

单选题Doctors believe that secondhand smoke may cause lung cancer in people who do not smoke. Nonsmokers often breathe in the smoke from other people's cigarettes. This is secondhand smoke. The U.S. Environmental Protection Agency reports that about fifty-three thousand people die in America each year as a result of exposure to secondhand smoke. The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals harm a nonsmoker's health. Recently, though, scientists expressed their opinion after they studied a large group of nonsmokers. They discovered that even nonsmokers had unhealthy amounts of these toxic chemicals in their bodies. As a matter of fact, almost all of us breathe tobacco smoke at times, whether we realize it or not. For example, we cannot avoid secondhand smoke in restaurants, hotels, and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted. It is even harder for children to avoid secondhand smoke. In America, nine million children under the age of five live in homes with at least one smoker. Research shows that these children are sick more often than the children who live in homes where no one smokes. The damaging effects of secondhand smoke on children also continue as they grow up. The children of smokers are more than twice as likely to develop lung cancer when they are adults as the children of nonsmokers. The risk is even higher for the children who live in homes where both parents smoke.
