Question

【题目】The businessman claimed ________from Harvard, while in fact, he never went to college.
A.to have graduated
B.to graduate
C.having graduated
D.graduating

Answer 1

【答案】A
【解析】claim to have done sth. 意为“声称曾经做过某事”。to have done是不定式的完成式，表示动作发生在谓语动词之前；句意：那个商人声称他毕业于哈佛大学，但实际上他从没上过大学。根据句意，故选A。
