 一、概说
英语中的-ever 词主要包括 whatever, whoever, whichever, whenever, wherever, however 等,其中可引导名词性从句的主要有 whatever, whoever, whichever。这里所说的名词性从句主要指主语从句和宾语从句,它们通常不用于引导同位语从句,同时也很少用于引导表语从句。如:
Whatever he said was right. 无论他说什么都是对的。(引导主语从句)
I don’t believe whatever he said. 无论他说什么我都不信。(whatever什么意思引导宾语从句)
在某些特定的语境中,也可用于引导表语从句。如:
What he wants to get is whatever you have. 他想得到的是你所拥有的一切。
二、whatever引导的名词性从句
whatever的意思是……的一切事或东西,可视为what的强调说法,其含义大致相当于anything thatwhatever在从句中可用作主语、宾语、定语。如:
