Question

【题目】—Is that Tom over there?

—It ____ be him. He is on the plane to Chengdu now.

A. can’tB. might notC. must

Answer 1

【答案】A

【解析】

句意：——在那边的是汤姆吗?——不可能是他。他现在正在飞往成都的飞机上。考查情态动词辨析。can’t不可能，表推测；might可能，也表推测，但might not表示“可能不”；must一定，表肯定推测。根据下文He is on the plane to Chengdu now.可知can't符合语境，故选A。
