【正确答案】 D

【答案解析】[听力原文] West Point is a four-year school in New York State that educates future Army officers. The students are called cadets. They do not have to pay for their education. They must agree to serve on active duty in the Army for at least five years after they graduate. A young man or woman must be nominated to the academy, usually by a federal or state lawmaker. Nominees also must satisfy the entrance requirements. These include being in excellent physical condition and getting good grades in high school. In addition, students from other countries can also attend the academy. The international students must be nominated by their home governments. And also they must satisfy physical and educational requirements. Surely they must do well in TOFEL. Home governments may have to pay up to sixty thousand dollars a year for each student they send to West Point. Among the countries with cadets at the academy this year are Afghanistan, Bulgaria, Cameroon, Costa Rica, Iraq, Kazakhstan, Sri Lanka, and Tunisia. Each year, the United States Defense Department invites countries to nominate students to West Point and to the Navy and Air Force academies. Not all the countries take part in the program. Up to sixty foreign cadets at any time can attend the academy. And the interested students must seek information about the program at their local American Embassy. The embassy's Defense Cooperation Office will know how the students can be nominated. What must the cadets do after graduation from West Point? 首先根据各题选项中提及较多的词汇students可推测录音内容和学生有关，而根据army，military training等与军事有关的词，可推测是军事学校学生的情况。录音中说学生毕业后必须在军队中至少服役5年，因此选D。
