大全694：非限定性定从的主谓一致

gmat700+

  The auto industry has experienced one of its most significant trends in the last 50 years, which is the migration of motorists from passenger cars to minivans, sport utility vehicles, and pickups.

(A) The auto industry has experienced one of its most significant trends in the last 50 years, which is

(B) Of the trends the auto industry experienced in the last 50 years has been one of the most significant

(C) In the last 50 years, one of the most significant trends that the auto industry has been experiencing has been

(D) One of the most significant trends that the auto industry has experienced in the last 50 years is（D）

(E) In the last 50 years, the auto industry experienced one of the most significant trends that it has had, that of

看了这题的大全简注对A的解释后，发现一个知识点不是很明确：one of n.(pl.), which ……结构中，逗号后面的非限定性定语从句的谓语使用但是形式还是用复数形式?我只知道one of n.(pl.)的限定姓定语从句的谓语是用复数形式的。谢谢NN！

个人认为one of n.(pl)的结构，其后的定从谓语是不定的，因为定从可以修饰one，也可以修饰n.(pl)，所以，即便是has，也不能算错，因为其明确暗示了指代对象。

one of n.(pl.), which ……结构，主要是看which从句修饰谁。如果要跳跃修饰的话，一般OG中的句子会给出谓语动词单复数来确定修饰的是前面的具体的先行词是谁？一般情况优先选择就近修饰。

不好意思，没看到stoneren的回答。同意stoneren的观点。

不好意思，现在才看到回帖，谢谢两位！

那么，这道题A选项错误是因为非限定性定从修饰对象模糊吗？如果划线部分 which is 是对的，那好像只有认为 which is ……修饰  the last 50 years，才能把它排除了。

不知道我说得对不对？

我认为A的错误在于不应该用非限定从句而应该用限定性定从；至于定从的修饰对象，我认为which is还是修饰one的，而不是修饰复数名词years。

嗯，同意这个说法。但是，你是怎么判断A应该用限定性定从，而不是非限定性定从的呢？我觉得A用非限定性定从并没有破坏句子的合理意思啊！这题A和D的唯一区别好像就是句子所表达的重心不同，A强调的是auto industry经历了一个trend，后面用非限定性定从补充了一下这个trend是什么。D强调的就是这个trend是什么什么。但是，我记得某位牛牛曾说过，新东方把句子重心的作用过分夸大了，其实在逻辑意思合理语法表达正确的情况下，句子重心并不是主要考虑的因素。所以，A和D虽然有各自的重心，但是，我觉得都是合理的表达。

请stoneren继续指教。

According to Shi Lin grammar,

one of + plural + Vt (single),

one of +plural + that + vt (plural), however,

The only one that is....

And I think in A "which" should refer to trends instead of years.

你说which指的是trends，那么就是说which后面的谓语动词应该用复数are了？可是，我觉得用are逻辑不通啊！难道auto industry经历的所有trend都是the migration?

请继续讨论……

支持stoneren的看法，觉得语法题的判断其实也是逻辑为先，应该首先根据逻辑意思来判断修饰对象，然后再根据语法规则来判断句子的用法是否跟逻辑意思相符。规则是死的，但是逻辑是活的。

另外，我觉得这题的关键是A里面的in the last 50 years有歧义，既可以修饰trends做定语，又可以修饰auto industry做状语，意思上有差别。

请指正。
