OG 1

顾风

OG里有提到，对一个群体如果指一个共有特征的时候，这个特征可以用单数。

例如：monkeys which have an extra bone in their ears.

以下是引用薰衣紫草在2005-4-18 9:21:00的发言：

A. 限定性修饰, 起限制约束作用:

1.由that 引导的定语从句, (that只引导限定性定语从句, 前面不会有逗号)

2.由前面没有逗号的一wh开头的词(who, which...)引导的定语从句,

3.with引导的短语

OG-141

141. Unlike transplants between identical twins, whose genetic endowment is the same, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.
(A) Unlike transplants between identical twins, whose genetic endowment is the same
(B) Besides transplants involving identical twins with the same genetic endowment
(C) Unless the transplant involves identical twins who have the same genetic endowment
(D) Aside from a transplant between identical twins  with the same genetic endowment       (C)
(E) Other than transplants between identical twins, whose genetic endowment is the same

疑问：

按照薰衣紫草NN总结的规则，此题B/C/D应该都是同样的逻辑错误。但是OG－141的解释中指出了B/D选项限制性修饰带来的逻辑错误，却认为C选项是正确答案。

In B and D the expression identical twins with the same genetic endowment wrongly suggests that only some identical twin pairs are genetically identical. Choice C, the best answer, solves these problems by using a clause introduced by Unless to describe the exception to the rule and a nonrestrictive clause beginning with who to describe the characteristic attributed to all identical twins.

疑惑中，请NN帮忙～～！！

仍然疑惑那这里that occurred
                    和occurring的错误原因到底是限定性非限定性定语从句的问题还是仅仅因为现在分词表示动作的反复、正在进行和延续，用在这里不合适，后面还有时间状语when，只能是过去分词表示一次性发生的动作，，请教NN

这个问题问的真是太好了,我查了1个小时关于限定非限定的资料,有如下两点体会.

1. 根据arizon state university的教材, who也有可能引导非限制性定语从句.

2. 所有我查到的美国人的资料都没有把是否有逗号当作唯一的标准来判断; 真正唯一的标准都是要求从意思上来判断,是否是必须的,不可或缺的内容,所以我们自己做的这些流传甚广的总结至多只能是适用于大多数情况,并不绝对.

如下就是老美的划分!

Restrictive                                                                Non-Restrictive (appositive/parenthetical)
a. begins with wh words or that                                may begin with wh words
b. presents highly relevant information                    gives “extra” information
c. is not separated from the sentence                      is separated by commas, dashes, or parentheses

这里不能用occurring，因为主句现在时态，occur过去时态，两者不一致时一定要用定语从句

chenbinqing

这题我知道  我一本高中的语法书里说 如果有明显的时间状语 不能用分词 只能用定语从句
