【例题】
Danny was late for school because the
traffic was too heavy.
Danny was late for school
the heavy traffic.
答案：because of
Danny was late for school because the
traffic was too heavy.
Danny was late for school
the heavy traffic.
答案：because of
答案：because; of
解析：
本题考查because和because of的用法区别。because是连词，后接完整的句子；because of是介词短语，后接名词、代词或名词短语。原句中“the traffic was too heavy”是完整句子，此处需转换为搭配名词短语“the heavy traffic”的表达，因此填入because of，分两空填写。
