129. In an effort to reduce their inventories, Italian vint­ners have cut prices; their wines have been priced to sell. and they are.
have been priced to sell, and they are
are priced to sell, and they have
are priced to sell, and they do
are being priced to sell, and have
had been priced to sell, and they have
In choice C, the best answer, do is correctly used in place of the full verb do sell; in this verb, do is a conjugated form and sell is in the infinitive form, corresponding to its previous use in the sentence (in the phrase priced to sell). In choice A, the omitted word is selling; in B, D, and E, it is sold. Neither of these forms corresponds properly to to sell earlier in the sentence. Also, in E, the past perfect had been priced signifies that the wines had been priced to sell before the prices were cut.

Og的意思是(撇开时态错误不说),如果BDE要成立的话,必须变成

b. and they have sold

d, and have sold

e. and they have sold

意思是如果要省略,必须补出主动词,只补助动词是不够的?

这类的省略还有什么要注意的内容?麻烦哪位给我上上课,谢谢!!!

我的语法很菜，全都是靠平时日常用到的积累起来的。没什么理论总结。

只能就题论题。希望能抛砖引玉。

要省略动词，动词应在句中出现过，而且词的形式应不变。

A/B/D/E 中的动词根本不能省略。因为，文中是sell,不是sold.

见笑了。
