Question

Jim didn’t realize his little sister was crying _____ what he had said.

A．because

B．because of

C．as

D．since

Answer 1

B

試題分析：考查連詞和介詞用法。ACD三項表示原因的時候，以后要接完整的句子做原因狀語從句。只有because of后面要接名詞或者名詞性的短語做賓語，形成介詞短語在句中做狀語。本題的what he had said="his" words是指他所說的話。故B正確。
點評：本題是高一年級考查的重點內容，在于because of后面要接名詞或者名詞性的短語做賓語，形成介詞短語在句中做狀語。一定要辨別后面的內容是句子還是短語。
