12.【2020 •四川攀枝花】—Could you tell me_____________ this morning?
—I am sorry, Mrs. Lin. I got up so late that I couldn't catch the first bus.
A．why were you late for class B．if you were late for class
C．why you were late for class D．how you went to school
【答案】C
【解析】句意：——你能告诉我你今早为什么迟到吗？——对不起，林老师。我起的太晚了以至于没能赶上第一班公交。考查宾语从句。why were you late for class你为什么上课迟到；if you were late for class是否你上课迟到了；why you were late for class你为什么上课迟到；how you went to school你怎么上学的；根据句意理解及后句的回答I got up so late that I couldn’t catch the first bus.可知，这里表达的是“为什么迟到”，所以应该用why引导，而宾语从句要用陈述句语序，所以排除A选项，故选C。
