选择题
a reward of $1,000 will be given to can provide any clues to the case which has been investigated by the police for nearly half a year.
A．whoever
B．whomever
C．anyone
D．who
答案
答案：A
考查whoever引导的名词性从句，to后面接的是宾语从句，whoever引导宾语从句相当于anyone who，因为在宾语从句中是做主语的，不能用whomever，句意：一千美元的奖赏将给予提供警方近半年来一致调查的案件线索的人。选A。
