问题 Timothy Ray Brown, the first man cured of HIV, initially opted against the stem cell transplant that _____ history.
选项 A、could have later made
B、should have made later
C、might make later
D、would later make
答案 D
解析 本题考查时态和情态动词的用法。主句的谓语opted against用了一般过去时，而选项中都包含时间副词later“后来”，故判断此处应用过去将来时，D项的过去将来时符合此处的用法，故选D。could have done表示“过去本来能做某事却没有做”，should have done表示“过去本该做某事却没有做”一般不跟later连用，首先排除。根据常识，我们知道干细胞移植是有名的疗法，C项的might表示可能性很小，也不符合要求，可排除。
