标题: 请教XDF-13-15
15. Biologists believe that they have found one of the
substances that tell individual genes both when to
become active and when to remain quiescent in the
earliest phases of an embryo's development.

(A) tell individual genes both when to become
active and when to remain
(B) tell individual genes both at which time they
should become active or should remain
(C) tells individual genes both when to become
active or remain
(D) tells individual genes both when to become
active or when to remain
(E) will tell an individual gene both about when it
should become active and remain

答案:A,我明白, 只是A不是也错了吗?tell修饰one,要用单数啊?

谢谢.

不对啊,A of B的中心词是A,所以one of the substances 中,tell修饰one.

偶是排除地

是不是有点弄混了呀！！如果在一个句子中，one of the substances做主语，而tell做它的谓语的话那么就是姐姐所说的要用tells了。可是问题是这里的tell做定语从句的谓语，而定语从句所修饰的却不一定是a of b的中心词吧！！有可能是b，这要看意思，就像这道题定语从句修饰的是substances所以要用tell。

我也得了A,也是排除法,只是A不对.

MM说的不对吧,A of B的原则难道会因为是不是定语从句而改变?

作者: linlin315 时间: 2003-7-14 12:38
没有改变啊，我的意思是：之所以要确定中心词（a of b）不就是想主谓一致吗？？
而定语从句中没有规定说这个定语从句一定就是修饰中心词的吧？that也可以修饰b这个名词啊。而且一般为了避免歧义，that都会就近修饰的。但是这也不是绝对，that修饰谁更多的要取决于意思，that这里修饰substances所以谓语当然要用tell！！不对吗？并不是说a of b的原则会因为是不是定于从句而改变。而是这里的a根本就不是定从的主语，b才是。

一般来说在A of B结构的中心词是A,后面定从修饰的是A,但这里的one of noun(pl.)结构是比较特殊的，因为one 是后面复数名词的子集，所以定从的先行词应该是这个复数名词；大家只要记住这个习惯用法就好了！

如，With its plan to develop seven and a half acres of shore land , Clevelan is but one of large number of communities on the Great Lakes that are looking to its waterfront as a away to improve the quality of urban life and attract new businesses.

Joy, here the subject is substances. A is 100% correct. And be care with two similar phrases:

1. I am one of those people who have turned in the final paper on time.

2. I am the only one of those poeple who has turned in the final paper on time.

我记得新东方的老师也说过
one of sb. that /who pl.
the one of that /who single
