Prices of daily goods _______ through a computer can be lower than store prices.

A．are bought

B．bought

C．been bought

D．buying

答案

B

解析

考查非谓语动词用法。bought through a computer是一个过去分词短语，在这里作为定语修饰daily goods. Goods与buy构成被动关系，所以用过去分词的形式。bought through a computer="which" is bought through a computer.句意：通过电脑购买的日常用品的价格可能比商店里的价格要低。
