A. to be attending
B. that attend
C. to be attended
D. that attending
答案:
(答案→)A. to be attending
B. that attend
C. to be attended
D. that attending
解析:A考察句式结构,由语境可知据说他在美国的一所大学学习音乐,sb be said to do sth据说某人要做某事;题干转换成主动形式:we say that he is attending college in America,主语he和attend之间构成主动关系。故排除C项。BD项与语境不符。
