129. 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
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).
看了以前的讨论,有个地方还是不明白,解释中do is correctly used in place of the full verb do sell,那么还原就是。。。。and they do sell意思是“这些酒确实卖得很好。”但是in this verb, do is a conjugated form and sell is in the infinitive form,这句话又说do是一个什么形式,sell在不定式中,怎么理解呢? |
