[19]Do you have a tough math test coming up? Then listen to some classical piano music just before the test. You might end up with a higher score. Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18th century composer before taking a math test. They were surprised to find that the students’ scores jumped 8 to 9 points. [20]The music seems to excite nerve activities in the brain similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn that before you get too excited about applying this method to your math test, [21]you should remember that brain-exciting effects last only 10 to 15 minutes. Would rock music work as well as the piano music did? No, the scientists say. In fact, the less complex music might even interfere with the brain’s reasoning ability.
19. What is this passage mainly about?
20. Why can classical music play a positive role in problem solving?
21. What is one of the findings of the research?

选项 A、How to improve your reasoning ability.
B、Why classical music is popular with math students.
C、The difference between classical music and rock music.
D、The effects of music on the results of math tests.

答案 D

解析 题目询问文章的主旨是什么。关键是要听到文章开头的三句话,由此可知D正确。主旨类题考查考生对短文的主题或主旨大意的概括理解,一般出现在短文的第一题或者最后一题。
