Question

【题目】-- Sam, you look tired today. What's the matter?

--- I was busy I didn't go to bed until midnight yesterday.

A.too; toB.so; thatC.so; to

Answer 1

【答案】B

【解析】

句意：——Sam，你今天看起来非常累。怎么啦？——我如此忙，以至于我直到昨天半夜才睡觉。

本题考查固定句型。too+形容词/副词+to do sth“太……而不能做某事”，so+形容词/副词+that+从句，表示“如此…….以至于…….”，结合句意，表示如此忙，以至于睡觉晚，故选B。
