本题考查原因状语从句引导词的用法。
because表示直接原因，强调因果关系的必然性。
在这个句子中，“我昨天没去学校足球比赛”的直接原因是“我得了重感冒”，这种因果关系非常明确。
since表示“既然”，通常强调已知的原因或前提，在这里不太合适；as表示“由于”，语气比because弱，更多地表示一种附带的原因，在此语境下没有because准确；for也可表示原因，但更多用于补充说明，一般不放在句中引导原因状语从句。
2. ____ it was raining heavily, we had to stay at home.A. BecauseB. SinceC. AsD. All of the above答案解析：D。
这几个词都可以引导原因状语从句。
Because强调直接原因，由于雨下得很大所以我们不得不待在家里，因果关系直接明确；Since在这里可以表示“既然”，雨下得很大是既定事实，所以我们待在家，语义通顺；As表示“由于”，因为下雨所以待在家，也符合逻辑。
所以这三个词在这个语境下都可以使用。
3. He didn't pass the English exam ____ he didn't study hard enough.A. becauseB. sinceC. asD. because of答案解析：A。
because强调直接原因，“他没通过英语考试”的直接原因就是“他学习不够努力”。
since和as虽然也可表示原因，但语气上没有because强烈直接。
而because of后面要接名词、代词或动名词，不能接句子，所以在此处不合适。
