答案：
(答案→)A. many a student expresses
B. in which more than one student express
C. that most of students express
D. the majority of students expresses
解析：考查定从和固定结构。a way是定从 what they think to others.
的先行词，关系代词可以是that，in which或省略，many a student和more than one student作主语时，谓语动词用单数，所以选A。C项应为that most of the students express;D项应为the majority of students express。
