A teacher was about to give a student a zero for his answer to a physical question, 　21　 the student said he should　 22　 a perfect score if the system were not　 23　 against the student. I was selected as a judge for it. I read the　 24　 　:“Show how it is possible to determine the　 25　 of a tall building　 26　 the aid of a barometer (气压计).”The　 27　 　answered:“　 28　 　the barometer to the top of the building, fix a long rope to it, 　29　 the　 30　 to the street, and then bring it up, measuring the length of the rope. The length of the rope is the height of the building.”

I pointed 　31　 　that the student really had a strong reason for a full score, since he　 32　 the question completely and correctly. On the other hand, 　33　 a full score were given, 　34　 could well contribute to a high grade for the student in his　 35　 course. A high　 36　 is supposed to certify competence in physics, but the answer did not confirm (证实，确定) this. I suggested that the student have another try at answering the question. I was not surprised that the teacher agreed, but I was surprised that the student did.

I gave the student six　 37　 to answer the question, with the warning that his answer should show some knowledge of physics. 　38　 　the end of five minutes, he had not written　 39　 . I asked if he wished to　 40　 , but he said no. In the next minute, he dashed off his answer, which was proper and made the teacher give up his thought, and I gave the student almost a full score.
