请教og35届时的一句话

35.   In June of 1987, The Bridge of Trinquetaille, Vincent van Gogh’s view of an iron bridge over the Rhone sold for $20.2 million and it was the second highest price ever paid for a painting at auction.

(A) Rhone sold for $20.2 million and it was

(B) Rhone, which sold for $20.2 million, was

(C) Rhone, was sold for $20.2 million,

(D) Rhone was sold for $20.2 million, being（C）

(E) Rhone, sold for $20.2 million, and was

A comma is needed after Rhone in choices A and D to set off the modifying phrase that begins Vincent...; without the comma, the phrase appears to be part of the main clause, and it is thus unclear what noun should govern the verb sold.

答案没有问题。

问题是og的这部分解释究竟什么意思？我觉得“n1,n2 +vo"是很常见的一种句型啊。

首先，我想请你能否找到一个合理的n1,n2 + v用法的句子作个例证，谢谢!

其次，针对这题

主语是：The Bridge of Trinquetaille,

同位补充解释：Vincent van Gogh’s view of an iron bridge over the Rhone

句子的谓语：sold for $20.2 million

如果没有逗号，谓语岂不成了同位补充解释的谓语，而不是整个句子的谓语了。所以，在此处，逗号是必须的。

再举个例子：

Reagan, the pre-President of the US, died. 如果US后没有逗号，那么无法表达是里根死了，而是指美国的前总统死了，到底是哪个前总统？不知道。另外，Reagan在句中是何成分也不清楚。

唔，stoneren 解释的很有道理。

我查了一下og，上面有这样一道题：

56.   Architects and stonemasons, huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport.

(A) huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport

(B) without the benefits of animal transport or the wheel, huge palace and temple clusters were built by the Maya

(C) the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel

(D) there were built, without the benefit of the wheel or animal transport, huge palace and temple clusters by the Maya（C）

(E) were the Maya who, without the benefit of the wheel or animal transport, built huge palace and temple clusters

这道题就是典型的“n1, n2+v".

综合这道题和stoneren 的解释与举例，我想是不是这样：

当n1是同位补充解释时，n2后不加逗号是可以的。比如这个og56

当n2充当同位补充解释时，就需要加逗号。比如og35。

不知道这样对不对，请指教。

谢谢找到这道有典型作用的题目。

你说的不错，这道题中的主语是the Maya。你关于逗号的分析，我个人认为是正确的。

上面敘述 og56  "当n1是同位补充解释时，n2后不加逗号是可以的" 我在 Q56句子裡面看不出來這樣的結構...麻煩大家解說一下...thanks

Architects and stonemasons, the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel.

Architects and stonemasons, 是其后the Maya的同位补充解释.

那么，请问：反过来

The Maya , architects and stonemasons built huge palace and temple .......

就不对了。是不是？

我觉得没什么区别吗！！！！？？？？？？？？

而35题，就不同了，显然。

如果没逗号，则sold变成了Rhone的后至定语。则句子没有谓语。

所以，我觉得关键不是n1，n2的事，而是是否引起歧义

不支对不对？？？

请nn指点指点〉

这其实是定语从句省略 which was

同位语虽然是等价的意思, 但peajack, 我认为主语和同位语的位置不能互换.

如果architects and stonemasons作主语, 那在逻辑上是说不通的. 因为是the Maya建造了那些宫殿和庙宇without of benefit..., 而不是随便的一些建筑师和石头匠(泛指).
