题目内容
19.I was late this morning because the traffic was heavy.(改为简单句)I was late this morningbecauseof the heavy traffic.
分析 因为交通堵塞,今天早上我迟到了.
解答 答案:because of.原句是含有because引导的原因状语从句,结合下文the heavy traffic是名词短语,故用because of表示因为,of是介词,后加名词代词或动名词,故答案是because of.
点评 because是连词,其后接原因状语从句或回答以why开头的问句;
而because of是复合介词,其后接名词、代词或动名词,或者what引导的名词性从句.
