【题目】By the time I saw the angry expression on his face, I ________ exactly what I was having to face.
A. knew B. had known C. would know D. have known
在线课程【答案】A
【解析】考查动词时态。句意：我一看到他脸上生气的表情，我就知道我要面对什么。尽管句中有by the time引导的时间状语从句，但主句谓语所表达的动作不是发生在从句谓语所表示的动作之前，而是几乎同时发生，所以用一般过去时。By the time此处近乎于at the time之意。故选A项。
