Question

He kept thinking of the question whether it was ____ for his father to change the habit of a life time in such a short time.

A．possibly

B．probable

C．likely

D．possible

Answer 1

D

考查詞義辨析及用法，橫線前是was，所以應用形容詞，可排除A，probable 很可能，likely 可能的，常用短語：be likely to do ，possible 可能的，常用句型： it is possible for sb to do ，句意：他一直在思考這個問題對他的父親來說在如此短的時間之內是否可能改變生活時間的習慣。所以選D。
