Question

【题目】— Why were you late for school, Jack?

— Sorry. I was late for school _______ the heavy traffic.

A.becauseB.sinceC.because ofD.as

Answer 1

【答案】C

【解析】

句意：——为什么你上学迟到了，杰克？——对不起。我上学迟到因为交通拥挤。

考查介词短语。because因为，引导原因状语从句；since由于，引导原因状语从句；because of因为，后跟名词、名词短语或代词宾格；as由于，引导原因状语从句。根据the heavy traffic可知，后跟名词短语只能用because of，故选C。
