Question

【题目】—Today's young people can't live without smart phones.—They keep their hands on the phones wherever they go, even while they _______ meals.
A.have
B.are having
C.were having
D.will have

Answer 1

【答案】B
【解析】句意：——今天的年轻人没有智能手机无法生活。——他们无论走到哪里，甚至吃饭时，手里都拿着手机。While后跟句子，所以这里缺少的是谓语动词，在吃饭的时候做某事应该用现在进行时。故选B。
