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

A. are bought

B. bought

C. been bought

D. buying

题目解答

答案

B. bought

解析

步骤 1：分析句子结构
句子的主语是 "Prices of daily goods"，谓语是 "can be lower"，宾语是 "than store prices"。因此，空格处需要一个非谓语动词来修饰 "Prices of daily goods"。

步骤 2：确定非谓语动词的形式
"Prices of daily goods" 与 "buy" 之间是被动关系，因此需要使用过去分词 "bought" 来表示被动关系。

步骤 3：验证句子结构
将 "bought through a computer" 放入句子中，句子结构完整，符合语法要求。
