1. whatever, whoever, whomever, whichever既可引导名词性从句,也可引导状语从句;而no matter + what/who/whom/which只能引导状语从句,也就是说,我们如果要选择一个用来引导状语从句的连接,则既可用whatever, whoever, whomever, whichever,也可用no matter + what/who/whom/which。
2. whenever, wherever, however与no matter+when/where/how都引导状语从句,且可互换。如:
(1)Whoever breaks the law will be punished.
(2)If you break the law, you will be punished, whoever/no matter who you are.
(3)In peace,too,the Red Cross is expected to send help wherever/no matter where there is human suffering.
【例10】Please call my secretary to arrange a meeting this afternoon, or ______ it is convenient to you.
A. whenever B. however C. whichever D. wherever
答案:A。
点拨:此题根据意思,是在谈论安排会议的时间,所以要用whenever,这里的whenever it is convenient to you表示“任何一个你方便的时间”。
