单选题" They laughed when I sat down at the piano, but when I started to play... ! " These words may be among the most successful in advertising history. Although the ad has not run for many years, the slogan is still remembered. It was written in 1925 for the V. S. School of Music, to sell home music lessons. The ad has great appeal. It pictures a handsome man sitting at a piano in front of smiling guests. It tells the story of Jack, who has secretly learned to play the piano through a mail-order course. His friends at a party all scoff when he sits at the keyboard. But as he plays the first notes of Beethoven's "Moonlight Sonata," they all amazed. When he finishes his flawless performance, the listeners shower him with applause and praise. Jack tells his friends that he learned to play through the V. S. School of Music. He explains that he was taught through a new method, using no laborious scales and no tiresome practicing. He didn't even have a special talent for music! In the ad, others, too, could increase their popularity and gain happiness. The writer of this ad, John Gaples, called this style the "Walter Mitty approach." Walter Mitty is a character in a short story by James Thurber, who daydreams of taking part in great adventures. Although this ad seems old-fashioned now, many people still dream of such easy social success.

单选题Anyone who has ever attended a university knows that the quality of lecturers varies greatly. A few are very effective communicators, conveying the substance of their lectures clearly and interestingly and inspiring students to want to know more about the subject. Others produce dull lectures from which the students learn little and which are likely to kill any interest they may have in the subject. Lecturing is a major part of a university lecturer's job and it would seem reasonable that effectiveness in this task should be a major standard in assessing a lecturer for promotion. However, it is very often the case that far more weight is given to such factors as participation in research, number of publications and even performance of administrative duties. My point of view is that a lecturer's lecturing should be regularly evaluated and that the best people to carry out this evaluation are those directly on the receiving end. It could, of course, be argued that students are not competent to evaluate the academic quality of lectures, If anyone should evaluate lecturers, it should be their colleagues. However, I am not arguing that students should be asked to comment on the academic content of lectures, but to evaluate the effectiveness. I suspect that many of the objections to student evaluation stem from the fear some lecturers have of being subject to criticism by their students. However, lecturers should see such evaluation as an opportunity to become aware of defects in their lecturing techniques and thus to become better lecturers. Such a system should benefit both students and lecturers as well as help department heads to assess the strengths and weaknesses of their teaching staff.
