OG129FAINT

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

这题比较晕：答案C

为了尽力减少他们的存货，意大利葡萄酒商已经降低了价格。他们（酒商）的酒被定价销售，他们（指酒还是酒商？）的确是卖了。

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).什么意思，是说要和前面平形吗？

我有两个问题：1、题目中的THEY和THEIR分别指代了什么？酒商和酒吗？不违反同一代词在句中指代相同事物的说法吗？

1. their wines do sell

2. they = vintners, their = vinters', they = wines

3. Complet form:  Their wines are priced to sell, and their wines do sell.

本人认为代词指代应该一致，所以后面的they肯定指vintners,所以完整句子应该为：

Their wines are priced to sell, and they(vintners) do sell (at cutted prices).

至于答案C的解释个人认为不是要求平行什么的，而是根据上下文的意思，do应该指代sell.设想如果为price,上下文就感觉非冲突或重复。

不知理解是否有问题，待指教。

为什么大家总说they do sell? 如果do是stressing word, I think we shouldn't omit "sell" following it. So it is

Their wines are priced to sell, and they(vintners) sell (at cutted prices).

129. In an effort to reduce their inventories, Italian vint­ners have cut prices; their wines have been priced to sell. and they are.

(C) are priced to sell, and they do ,they 到底指什么?呜.......我觉得指酒商我比较理解,可是OG上的解释我觉得更象指酒啊.

個人認為In an effort to reduce their inventories, Italian vint­ners have cut prices; their wines are priced to sell, and they do.平衡對稱，沒有錯

這裡的they是指酒商，本題後半段是指酒商的酒被重新標價出售，而且他們(酒商)積極銷售中。

有朋友提到 do 是加強語氣，所以do 後面該補一個sell 才對，我比較傾向是省略sell the wines後，補上一個do(表sell the wines)來維持平衡 。

這可以參考OG199

199. Because the Earth’s crust is more solid there and thus better able to transmit shock waves, an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West.

(A) of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West

(B) of a given magnitude will typically devastate 100 times the area if it occurs in the eastern United States instead of the West

(C) will typically devastate 100 times the area in the eastern United States than one of comparable magnitude occurring in the West

(D) in the eastern United States will typically devastate an area 100 times greater than will a quake of comparable magnitude occurring in the West（D）

(E) that occurs in the eastern United States will typically devastate 100 times more area than if it occurred with comparable magnitude in the West

標準答案是D，為什麼是will呢，不過是 quake of comparable magnitude occurring in the West will devastate an area...的倒裝，既然後面都一樣，基於簡潔，保留助動詞 will，再加上由短到長的倒裝原則即可

同樣的OG129 ，(C) are priced to sell, and they do，就是省略sell their wines，既然都一样，就省略補一個助動詞do就好

個人意見請指教

標準答案是D，為什麼是will呢，不過是 quake of comparable magnitude occurring in the West will devastate an area...的倒裝，既然後面都一樣，基於簡潔，保留助動詞 will

nod ,here 保留助動詞 will because the different two quakes  are comapred with each other,so we should use will to identify there are two different quakes---quake in the west and quake in the east

otherwise some confusion will occur that  it is the  quake that occured in the west  and at the same time the same quake occured in the east.

i think the og 129 is in such case as :

Their wines are priced to sell, and they(Their wines ) do  (are priced to sell).

my understanding, to be discussed
