标题: 关于 one of+n.(复数)+that从句 的主谓一致 [打印本页] 作者: gmat700+ 时间: 2004-6-17 01:01 标题: 关于 one of+n.(复数)+that从句 的主谓一致
白勇在讲课时说: one of+名词复数+that从句的结构中，that从句的谓语动词要和of后面的名词保持一致，用复数形式。
但是，我在做阅读时对这条“公理”产生了疑问。在杨继阅读精解section 7第2篇中有一句话：Scientists have now investigated the effects of the spraying of Matacil, one of the anti-budworm agents that is least toxic to insect-pollinators. 这里的红字不分不就是白勇讲的这个结构？那为什么这里的that从句谓语动词用单数呢？白勇讲的这条“公理”还能作为判断选项对错的依据吗？

我当时在看到这篇文章时也产生过相似想法，但是，我认为由于GMAT文章都是择选一些论文，其作者或许会有一些语法上不严格的表达，而ETS那些编撰者也未必能发现，所以象类似的情况发生在阅读中，不必过于关注。另一方面，我认为one of the anti-budworm agents that is least toxic to其实也没有什么大的语法错误，that is从语法上只能修饰one，可以把of the anti-budworm agents理解为一个插入成分，不会对我们的理解造成歧异。但是，在语法考试中，我们还是应该倾向于更为标准的表达。作者: gmat700+ 时间: 2004-6-17 10:59
以下是引用stoneren在2004-6-17 3:04:00的发言： 我当时在看到这篇文章时也产生过相似想法，但是，我认为由于GMAT文章都是择选一些论文，其作者或许会有一些语法上不严格的表达，而ETS那些编撰者也未必能发现，所以象类似的情况发生在阅读中，不必过于关注。另一方面，我认为one of the anti-budworm agents that is least toxic to其实也没有什么大的语法错误，that is从语法上只能修饰one，可以把of the anti-budworm agents理解为一个插入成分，不会对我们的理解造成歧异。但是，在语法考试中，我们还是应该倾向于更为标准的表达。
谢谢你的回答。你所说的“更为标准的表达”就是白勇讲的那条“公理”对吧？

one of + 复数名词 + 单数谓语；
eg: One of my friends is in the US.（强调one）
one of + 复数名词 + 定语从句(从句复数谓语) + 主句谓语单数；
eg: One of my friends who are in the US will come to China.（强调friends）
only one of + 复数名词 + 定语从句(从句单数谓语)；
eg: Only one of my friends who is in the US will come to China.（强调only one）
以上的是行文的规律，并非所谓白勇的公理。我在http://forum.chasedream.com/dispbbs.asp?BoardID=23&ID=55441只不过是强调了在阅读中的可能的语法错误，从语法上讲阅读中的那个例子可以更好地被表达为：only one of the anti-budworm agents that is least toxic to insect-pollinators或one of the anti-budworm agents that are least toxic to insect-pollinators。 抱歉，我恐怕在前一个帖子中没有表达清楚。希望这次表达清楚了。
这里one of ns that+vs 就是说是修饰前面的名词咯。 我这个问题一直没有搞懂 因为that就近修饰。
--------------------------------
我觉得A of B that的问题比one of 复杂，偶至今只能用语意去理解，用其它错误去排除。没什么好办法。
可见不能简单地说that修饰前面名词。
the one of Ns that+Vs
one of Ns that+ V

事实上应该是这样,当only前面再加上the时定语从句才修饰one,光有only还不够,
另外,即使没有only如果one前面有the定语从句中动词也要用单数.
也就是说跟one前面有没有only没关,其实和one 前面有没有the有关

我认为rose mm说的是正确的。
但是，one of the anti-budworm agents that is least toxic用is是不是因为有least的原因呢？有没有关于one of +定从中有最高级时的用法说明？

我在高考英语能力突破（语法）这本书上看到：
one of + n(pl.) + 定从+ vs
this is one of the rooms that were damaged in the fire.
如果之前有the only, the very, the等限定词和修饰语时,定从中用v
she was the only one of the girls who was late for the meeting.
对于看意思判断one of ns 后的v是单还是复，这样太不定了，不好把握！
不过不知道参看高考的语法书（2003。8出版），可不可以解释GMAT的语法：）
作者: juliet01192000 时间: 2005-10-5 18:41
rosebudxiaojie有道理，是和THE 有很大关系的！
无THE 修饰ONE OF 时，定从修饰NS
有THE 修饰ONE OF时，定从修饰 THE ONLY ONE OF NS

原来集体讨论可以有这么多扩展的知识，而且还可以在相互帮助和提示下有更好的理解。所以回到这个经典阅读中"Scientists have now investigated the effects of the spraying of matacil, one of the anti-budworm agents that is least toxic to insect-pollinators." 我认为理解句意很重要。
1。"one of..."首先是并列说明“the spraying of matacil”, determined by 前半句是完整句和“toxic...”是描述“the spraying of matacil”.
2。"one of the anti-budworm agents that is least toxic....."是和“least”有关的。"that is.."相当于后置限制形容 “one of..”. 而出现“least”最高级中也只能来说明“one”,也既是“the spraying of matacil”

LZM的书里有很详细的注解：
1〉'one of' 结构作为主语时+V，'two of' + Vs
2> 'one of + n(pl.)+that/who'+V，因为在GMAT当中that，which，who 都closely follow the subject they modified, 所以他们都修饰n(pl.)
3>the only one/the first one of...+Vs
P.S. numbers of +n[c] ALWAYS WRONG
large sums of/quantities of +n+V : e.g. large sums of water ARE

“我想到为什么 (1) 错了。如果是 (1) 那样理解 He is [(one of those rare people) who believes in ancient myths].，那 those rare people 就没有着落，因为 who believes in ancient myths 变成只修饰 one。那么 those rare people 是什么人？/ Q6 v* w+ K3 @/ i

“我和我的改稿人讨论过这个用法。他认为全部都应该用单数，因为他把 one of those people、one of the things 等看做一个单位。虽然他是我认识的人当中英文最好的，但在这点我不同意他。

C. is compact when written but can lengthen considerably when being translated into English
D. are compact when written but can lengthen considerably in English translation
E. is compact when it is written but can lengthen considerably when translated in English
Ans D（B is not parallel. We want languages that *are* compact but *can* lengthen (both starred words are parallel verbs). "They" isn't just wordy or unneeded--it breaks parallelism. Also, "translated in English" is not idiomatic. Something can be translated *into* English, or it can exist in an English translation, but we don't translate "in English." It makes it appear as if the entire translation takes place within one language, which doesn't make sense.）
