问题补充：
I’m afraid nobody but his parents or Jim, his best friend, the secret.
A. are going to tell
B. have told
C. has told
D. have been told
答案：
A. are going to tell
B. have told
(答案→)C. has told
D. have been told
解析：该题涉及到主谓一致的问题。当主语是单数形式时，后面跟（together） with, as well as ,but, except, rather than等词语，无论这些词语后面带复数形式还是单数形式，谓语动词仍然用单数，故正确答案为C. nobody是不定代词，应该看作单数。本句可以理解为“除了他父母或Jim, 没有人说出这个秘密”。
