单选题Until the 1980s, the American homeless population comprised mainly older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the US Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient(变化无常的) and frequently frightened student population creates additional problems—both legal and educational—for already overburdened urban school administrators and teachers. Estimates of the number of homeless Americans range from 350,000 to three million. Likewise, estimates of the number of homeless school children vary radically. A US Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis, But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly. One part of the homeless population that is particularly difficult to count consists of the "throwaway" youths who have been cast of their homes. The Elementary School Center in New York City estimates that there are 1.5 million of them, many of whom are not counted as children because they do not stay in family shelters and tend to live by themselves on the streets. Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.

单选题The last cigarette? After reading an article entitled "Cigarette Smoking and Your Health", I lit a cigarette to calm my nerves. I smoked with concentration and pleasure as I was sure that this would be my last cigarette. For a whole week I did not smoke at all and during this time, my wife suffered terribly. I had all the usual symptoms of someone giving up smoking: a bad temper and an enormous appetite. My friends kept on offering me cigarettes and cigars. They made no effort to hide their amusement whenever I produced a packet of sweets from my pocket. After seven days of this I went to a party. Everybody around me was smoking and I felt extremely uncomfortable. When my old friend Brian urged me to accept a cigarette, it was more than I could bear. I took one guiltily, lit it and smoked with satisfaction. My wife was delighted that things had returned to normal once more. Anyway, as Brian pointed out, it is the easiest thing in the world to give up smoking. He himself has done it lots of dines!
