sell是一个特殊的谓语,sell是“卖”的意思,有及物动词和不及物动词两种用法 1）及物动词时
主动语态是sb sell sth,某人卖某物
被动语态就是sth be sold by sb ,某物别某人卖
2)不及物动词时
常用sth sell well表示某物卖的非常受欢迎
我想你不明白的应该是sth sell well这个用法吧,这里表示的是某物卖的好,因为they是指的是某物,是不及物动词用主动形式,相同的还有taste.
sth taste good
因为前面的谓语是用的are,其实前面的一句话就是一个信息,提醒你这句话应该用现在式,其实做选择题的时候,不要小看了一些辅助的话,他就给你提供了信息,很关键,单项选择题的每句话都相当的重要,还有就是有already做提示是现在完成式的标志,首先B的时态就是错误的首先排除
第一空填sell 我前面已经解释的非常清楚了
后面的两个谓语的主语都是they 当然第二空应该用现在完成被动式,
我想我已经讲的非常清楚了,希望对你有所帮助!

当然2…因为字典卖得好并不是只在过去，现在也是卖得好，所以用一般现在时。

sell 表示销量很好的时候，可以事物用主动
但是表示买的时候，事物做主语要用被动。
sell
be sold out
