单选题
Nobody but Tom and Mary ______ the secret.
A、
know
B、
knows
C、
have known
D、
is known
【正确答案】
B
【答案解析】
本题考查主谓一致的用法。主语是“nobody”,当后面跟有but,as well as,with,along with,together with,like,besides,except等词或短语,不能看做是并列主语,其谓语动词用单数形式。如:Zhang Ming as well as I agrees with them. Zhang Ming and I agree with them.
