这道题是考查主语从句吗？要看仔细定噢！
_________ with the right knowledge can give first aid.
A. Who                        B. Whoever                        C. Anyone                        D. Who everhttp://yingyu.chazidian.com
【分析】此题容易误选B，主要受以下这类句子的影响而形成思维定势：
Whoever says that is lying. 谁那样说，谁就是在说谎。
Whoever breaks this law deserves a fine. 违反本法者应予以罚款。
Whoever comes first can get a ticket free. 谁先来谁就可以免费得到一张票。
以上各例中的 whoever 引导的均为主语从句，它们均可换成 anyone who，但不能换成 anyone。上面的试题从表面上看，与以上各例很相似，其实有本质的不同，即 _________ with the right knowledge 中没有谓语动词，所以我们不能选 whoever。此题的正确答案为C，anyone 为句子主语，with the right knowledge 为修饰 anyone 的定语。请做以下试题：
(1) _________ with a good education can apply for the job.
A. Who                        B. Whoever                        C. Anyone                        D. Who ever
(2) _________ has a good education can apply for the job.
A. Who                        B. Whoever                        C. Anyone                        D. Who ever
(3) _________ having a good education can apply for the job.
A. Who                        B. Whoever                        C. Anyone                        D. Who ever
