Question

【题目】—I feel upset because I am too heavy.

—__________do more exercise to lose some weight？

A. Why don't B. Why not C. Why not to

Answer 1

【答案】B

【解析】句意：——我感到不安，因为我太重了。——为什么不多做运动来减肥呢？Why not和Why don't都表达一种询问的口气，提建议的语气；Why not+动词原形？Why don't+主语+do sth？Why not to表达错误；根据句中信息…do more exercise to lose some weight？推测该句句意：为什么不多做运动来减肥呢？根据do more exercise 推测前面用Why not；故答案选B。
