为什么一定选择B不能选择A?

Prices of daily goods___ through a computer 是主语
其中___ through a computer 是后置定语
to be bought 和 bought 都是被动语态,用来修饰goods均可以
但to be bought 表示将来时,陈述性的话用它不好

选B
Prices of daily goods(which are\were) bought through a computer can be lower than store prices.

(which are\were) bought through a computer 作daily goods的定语.which are\were可省略.

一定选B不选A因为:
TO BE BOUGHT-是将来时态,而句子是说一般上,经常性的,因此要用一般现在时态,所以一定要选BOUGHT.

BOUGHT,是被动,因此把BUY转换成BOUGHT

两个都可。但B更简明一些。
