问题补充:

--- . He is really busy preparing(准备) for the coming test these days.
A. Of course
B. I have an idea
C. 1 m afraid so
D. I don t think so
答案:
A. Of course
B. I have an idea
C. 1 m afraid so
(答案→)D. I don t think so
解析:Of course当然了;I have an idea我知道;1 m afraid so恐怕如此;I don t think so我不这么认为。句意:你认为彼得今天有空吗?根据下文,这些天他真的正在准备来临的考试。可知前文为否定回应,故选D。
