【正确答案】
D
【答案解析】[听力原文] Washington University in Saint Louis, Missouri, is a medium-sized university. It has eleven thousand students. 12% of them were international students, mostly graduate students. The University has schools for law, medicine, and social work. It also has a Business School, a School of Design and Visual Arts, and a School of Engineering and Applied Science. But more than 60% of courses are taught through the Arts and Sciences program. The new school year that begins this fall will cost about 50,000 dollars for undergraduates. That includes twelve months of living expenses estimated at 20,000 dollars. Graduate tuition differs by program. Tuition for the Master of Social Work program, for example, will cost 37,000 dollars in the coming year. The Master of Business Administration program will cost about 38,000 dollars. The university offers financial assistance to international students, including first-year students, but says its resources are limited. Scholarships are available. The university also offers a monthly payment plan to spread out the cost of tuition. It offers loan programs. International students in the United States generally cannot receive federal student loans. But they may be able to take out private loans, as many American students do. How are about two-thirds of the courses taught? 根据第1小题选项可知本篇短文与大学课程有关；第2小题为金钱数额；第3小题提到了贷款和奖学金，由此可以推断，该则新闻可能是对某所大学的介绍。 四个选项均为through引出的介词短语，表示方式，可判断本题以how提问，听到问题后立刻回忆所听新闻内容，结合选项作答。 新闻提到该大学设有法学院、医学院、社会工作学院，此外还设有商学院、设计与视觉艺术学院以及工程与应用科学学院，但是60%以上的课程都是由文科和理科学院教授的。由此可见，该大学三分之二的课程都是通过文科和理科学院教授的，故本题选D。
