已搜索，未解惑：从OG12SC 87题看出去。。

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

该解答的问题都看过了；但我自己一个很弱智的问题没解决。。。

我把我想问的简化一下，我觉得我之前说得不太清楚。

例1： their wines have been priced to sell, and their beverages __________ as well .

         their wines have been priced to sell, and they _________.

对象不同了，大家觉得怎么填？再加一个填空，大家也许能看得更清楚：

        their wines have been priced to sell, but their beverages ___________.

例2：Quinn failed to do th homework, but her brother did it.

        Quinn failed to do the homework, but her brother didn't.

        Quinn didn't fail to do the homework, but her brother did so.

这三个都是正确的；前两个语义都一样。但大家应该能够体会到不同的地方，强调的动作不同。例1也是要表达这个意思。

但为什么一读就知道是强调的不同，而不会有歧义呢？从语法上如该何解释呢？

什么时候知道应该强调哪一个动作呢？

请教请教请教请教请教。。。。。。。。。。我拜我拜我拜。。。
P.S.稍微修改了一下例1，以求使我的问题更加精确地被表达出来。

我心向明月

楼主考虑的明显要比我考虑得全面深入，我只是看了OG12的解释，然后就默认那样是对的，同求高人指点。

明月兄过奖了，明月兄不也是与我同样地对待嘛。我们就一起等吧。。

这个问题确实太困扰了。。。希望NN大牛达人大师G友大家所有人都来看看。。。

我知道我太贪心了。。。

红尘道士

例2，我想理解句子的关键是but转折，可能这有点象中文里面的
1.中国队大败美国队
2.中国队大胜美国队

红尘道士

例1的答案是不是
例1： their wines have been priced to sell, and their beverages have been priced to sell as well .

        their wines have been priced to sell, and they do.

       their wines have been priced to sell, but their beverages have not been priced to sell.
是不是中间还有些词可以省略的

umm...其实这个是跟代词指代一样的，通过逻辑意思来判断。正如ls所说，可以通过but来判断did指代的究竟是什么.
另外外加平行的一些规则：
their wines have been priced to sell, but their beverages have not. 通过Have not来表明省略的是been priced就行了。
或者their wines have been priced to sell, but their beverages do not. 通过do not来表明省略的是do sell里面的sell就行。

其实我也有发现，所以我把but放上来就是想起一个对比的作用的。版主和红尘兄都说得很对。
但我们在看and的情况，就不是很好分辨了。
their wines have been priced to sell, and their beverages have been priced to sell as well；
their wines have been priced to sell, and they do；
这两个句子，都是并列关系，但对象不同；但版主指出通过平行也能够给出信号;如版主给出的两个例子。
但向上面这两个句子的话，关系相同，但最后因为平行的部分不一样所以强调的部分不同；按版主的来说，是不是也可以通过平行强调同样的部分？比如，
their wines have been priced to sell, and their beverages have (been priced to sell) as well；
their wines have been priced to sell, and they have (been priced to sell)；
这样也行吧？只是强调的动作不同了。

现在我自己看来，如果可以通过平行强调同样的部分，那么其实OG只是设定要去强调后面的sell而已。如果选项中出现强调前面的削价动作，那确实未免不像OG了。没那么老奸巨猾，也就没那么可爱了。

至此我也明白了，如果有如上句子的结构，有两个或许更多动作在其中，通过关系连词和平行法则可以使句子强调的动作完全改变；知道是强调哪个动作，再根据那个动作的时态，语态，形式等来做平行，那问题就迎刃而解了。

忘说了，红尘兄，是的，某些可以省略的，版主和我的例子都有指出来。：）
