because what还是because of what有这样一道考题，答案是选哪个？He was sentenced to death _________ what he had stolen from the bank.A. that B. since C. because D. because of许多同学们认为此题应选C，因为关于 because 和 because of 的用法有如下区别规则：because是连词，其后接句子；而because of是介词，其后接名词、代词或动名词。此规则并没错，只是表述不很准确。一般说来，because 作为从属连词，用以引导原因状语从句时，其后应是一个不含有引导词的句子，而不能是 what 引导的从句。另一方面，本题中的 what he had stolen＝the thing(s) that he had stolen，也就是说，这个what-从句从本质上说，它相当于个一名词(或者更准确地说是一个受定语从句修饰的名词)，所以此题应选 because of。请看以下类似的例子：She cried because of what you said. 她哭是因为你说的话(www.nmet168.com)。He left angrily because of what you said at the meeting. 他生气地离去，是因为你在会上说的话。The man was punished because of what he had done. 他因为自己所做的事而受到了惩罚。
