Last year, however, the city’s high school dropout rate was significantly lower than the previous year’s rate. This is encouraging evidence that the program instituted two years ago to improve the morale of high school students has begun to take effect to reduce dropouts. Which one of the following, if true about the last year, most seriously weakens the argument? (A) There was a recession that caused a high level or unemployment in the city. (B) The morale of students who dropped out of high school had been low even before they reached high school. (C) As in the preceding year, more high school students remained in school than dropped out. (D) High schools in the city established placement offices to assist their graduates in obtaining employment. (E) The antidropout program was primarily aimed at improving students’ morale in those high schools with the highest dropout rates. 答案是A。 我可以理解A, 但是不明白怎样才能排除选项D. 文中退学的人是因为要找工作才退学的，从选项D，因为学校成立了 placement offices 来帮助毕业生找工作，所以学生就不退学了，而不是因为什么program 提高了morale，这不是他因削弱吗？作者: 深海的小美人鱼 时间: 2003-11-25 11:34
看看这句话High school students who feel that they are not succeeding in school often drop out before graduating and go to work.这里是说学生是因为觉得不可能在学校取得成功才辍学找工作的。仅仅是帮助学生找工作不能解决学生的moral问题。因此D没有在根本上削弱。作者: seanql 时间: 2003-12-1 00:10
因为学校成立了 placement offices 来帮助毕业生找工作，所以学生就不退学了
这句话的前提是学校帮不帮忙找工作决定学生退不退学，这在原文中并没有说明。如果单从学生不退学讲，这可以算作是支持。而原文的“drop out before graduating and go to work”的必然前提是学生可以go to work,也就是有地方可去，所以否定这个前提学生就不会退学，因此构成了“就业形势不好，学生就不退学了”这个他因
