-I am very worried about tomorrow's test.I'm afraid I can't pass this time.

问题描述:

-I am very worried about tomorrow's test.I'm afraid I can't pass this time.
-____!I'm sure you'll make it
A.Cheer up B.Come on
我选B为什么不可以

Cheer up 振作起来
Come on 表鼓励、催促等]快,走吧;进步;发生come on 也表示加油呀 这里说加油为什么不行?根据I am very worried about tomorrow's test.I'm afraid I can't pass this time.就知道他很丧气,没有信息B当加油讲时,是让他发挥最好的能力,而被鼓励的人并不定丧气所以A更加符合语境
