Were it not for ___ kept the manuscript in the bottom drawer, the tale it tells would have been lost forever.

A. anyone   B. who   C. whoever   D. no matter who

答案为C, 为什么不能选B?

解释：

1. whoever引导的从句指代的是人。who引导的从句指代的是事；

2. whoever 的含义是：the person who... 或anyone who...(无论(不管)是谁)。who常保留本身疑问的含义，即“谁”；

3. whoever引导名词从句既作从句的主语，又作主句的主语。who只作从句的主语。例如：

(1) Whoever comes first will get the first prize.

      Who will come to have dinner is not known.

(2) Whoever will be sent to work there will be given a large house.

      Who will be sent to work there hasn’t been decided yet.

(3) Whoever will go with us please sign your name in the form.

      Who will go with us has not yet been decided.

请观察下列句子并选择正确选项：

(B) 1. ______ comes will be welcomed to the open-air concert.

        A．Whatever    B．Whoever   C．No matter what       D．No matter who (10上海春考)

(C) 2. We promise____attends the party a chance to have a photo taken with the movie star.

        A. who     B. whom     C. whoever    D. whomever      (12福建)

(A) 3. The mother didn't know ____ to blame for the broken glass as it happened while she was out.      

        A. who　　B. when    C. how　　D. what  (02全国)

上面这个题目答案选C，whoever等于the person who。意思是“要不是那个把原稿放在抽屉底层的人，手稿所讲述的故事就永远遗失了。”本题侧重“那个人”，故选C。
