they是指代wine。 完整句子是:their wines have been priced to sell, and they do to sell. 这里的sell是vi.(不及物动词),表示“被出售”。 如果they指代vintners的话,sell应该是vt.,表示“卖”,后面需要跟宾语“卖的东西”,这样就和OG的解释冲突了。 OG解释: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 tis previous use in the sentence (in the phrase priced to sell) |
