题目内容
【题目】He failed the exam________ he was not hard-working, not________his bad luck.
A. because; because B. because of; because
C. because;because of D. because of;because of
【答案】C
【解析】
句意:他考试不及格是因为他不努力,不是因为运气不好。考查because用法辨析。because表原因,后接从句;because of表原因,后接短语。前句he was not hard-working,是句子,需用because;后句his bad luck是短语,需用because of。根据句意结构,可知选C。
