OG12 语法87题，有关sell的用法和动词省略问题~

lovedoublej

In an effort to reduce their inventories, Italian vintners have cut prices;their wines have been priced to sell,and they are.
(A)have been priced to sell,and they are
(B)are priced to sell, and they have
(C)are priced to sell, and they do
(D)are being priced to sell, and have
(E)had been priced to sell, and they have

正确选择为C
请问正确选项完成的句子是什么意思？怎么理解they do sell?sell是怎么在they do sell中被省略掉的呢？

lovedoublej

sell的含义：
2，to offer something for people to buy
3，to make people want to buy something

我可以基于以上解释把题目理解成这样么：酒被标价卖出，而它们也确实被卖出去了（有人买）？

lovedoublej

用do不用are是因为要平行的单词是sell不是are，而sell是不及物动词。
举例，1）They sell all goods for half price today.
          2)  The wine sells well.

and是表示前后意思平行么？我也不知道，姑且这么认为吧~因为是平行所以前后结构尽量一致，wine对应they，都表示酒。“are priced to sell”对应do(这是怎么个情况？！)，前句说“被标价来卖”，后半句如果用are则意思出错（变成酒确实被标价，无法理解），只能对应sell改成do,表示酒被卖出。

纯属个人理解，你要觉得不对就尽情地笑吧~~~~
