A third assumption is that products become best-sellers as a result of their being advertised on popular programs. While this may be true in some cases, it is equally possible that only companies with products that are already best-sellers can afford the higher ad rates that popular shows demand. Accordingly, a lesser-known product from a company on a smaller budget might be better off running repeated but less expensiveads on less popular shows than by running just one or two costly ads on a top-rated show.

　　In conclusion, the results of the cited study do not support the author s conclusion. To better evaluate the argument, we need to know the intended meaning of the phrase highly-rated. To strengthen the argument, the author must limit his conclusion by acknowledging that popularity in public television might not translate to popularity in commercial television, and that the best advertising strategy for companies with best-selling products may not be feasible for other businesses.

　　小编提醒：考生们可在日常生活中多读范文，多练笔，培养出好的语感和逻辑，这样才能在考试中写出优秀的作文。
