Jim didn’t realize his little sister was crying _____ what he had said.A.becauseB.because of C.asD.since

B解析试题分析：考查连词和介词用法。ACD三项表示原因的时候，以后要接完整的句子做原因状语从句。只有because of后面要接名词或者名词性的短语做宾语，形成介词短语在句中做状语。本题的what he had said=his words是指他所说的话。故B正确。考点：考查连词和介词的用法点评：本题是高一年级考查的重点内容，在于because of后面要接名词或者名词性的短语做宾语，形成介词短语在句中做状语。一定要辨别后面的内容是句子还是短语。
