Today computers ____________ in both cities and town.
A. are using B. are used C. were used

答案

解析

本题考查的是时态被动，根据today这个时间状语，可知为一般现在时的被动语态，am/is/are+being done,又因为主语为复数形式，be动词是are，句意：如今在城市和乡村电脑正在被使用。故选B

举一反三

－To keep safe, everyone_______ wear a seat belt(安全带) in a car.
A. is suppose B. are supposed to C. is supposed to D are supposed
