Question

【题目】I think young phubbers（低头族）are supposed to the time they spend their smart phones．

A. cut off；in B. cut down；on C. cut up；on D. cut in；in

Answer 1

【答案】B

【解析】句意：我认为年轻的低头族应该减少他们在智能手机上的时间。cut off切除；cut down减少； cut up切碎；cut in插嘴，干预。结合句意可知，句子第一个设空处中缺少“缩短”一词， spend time on sth. 在某事上花费时间，故答案为B。
