2．Today computers are really helpful．They_______ in both cities and towns．（　　）

A．

use

B．

will use

C．

are used

D．

are using

分析当今电脑真的很有用，城市和乡镇（的人）都在使用电脑．

解答答案：C
首先根据汉语表述的是一般性的事实，判断用一般现在时，主语they（computers）是动作use的承受者，所以用被动语态，一般现在时被动语态的构成是：主语+am/is/are+动词的过去分词，主语they是复数，be动词用are，use的过去分词是used，故选C．

点评本题考查时态和语态的辨析．每个时态都有标志词，熟记这些标志词是做题的关键．
