收录时间:2021-12-11    答题:高三英语(周老师)

【题目】It is estimated that hopefully about 0. 5 billion families_______5G terminals by 2025, when there is a sharp drop in price.

A.have used B.will have used

C.will be using D.are using

【答案】B

【解析】

考查时态。句意:据估计,到2025年,5G终端的价格将大幅下降,届时有望有约5亿家庭使用该终端。根据时间状语by 2025,可知用将来时态,这里表示在将来某一时间以前已经完成,所以用将来完成时态。故选B
