选择题
--Could you tell me ______________ for class 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
B．why you are late
C．why are you late
D．why you were late
答案
答案：D
题目分析：句意：你能告诉我你今早为什么迟到吗？对不起，林老师。我起的很早但是没能赶上第一班公交。Why引导的从句做tell的宾语，因此要用陈述语气。事件发生在过去，时态要用一般过去时。故选D。
