单选题 Which of tile following is TRUE?

A、 All students had traveled in commercial planes before.
B、 All students were nervous.
C、 Most students felt nervous traveling in commercial planes.
D、 Most students felt nervous when they were taken up in a fighter plan

【正确答案】 D

【答案解析】此考题为细节题。根据文章第2段最后一句，我们了解到，当学员们被带入战斗机机舱飞往天空时，most of the students felt nervous，就可以断定D正确。而A中的All应为Some。B的 All应为Most of，而且整个选项缺少时间状语，又过于绝对，C中所言并未在文中提及。
