18. GWD27-Q18:

The Near Earth Asteroid Rendezvous (NEAR) spacecraft will orbit the asteroid Eros for a year, slowly moving closer to the surface of the object to make ever more precise measurements that scientists hope will enable them to understand how the solar system formed some four billion years ago.

A.to make ever more precise measurements that scientists hope will enable them to

B.to make ever more and more precise measurements, which scientists are hoping to enable them

C.for making ever more precise measurements, and scientists hope that they will be able to

D.with the purpose of making more precise measurements than ever, and which scientists hope will enable them to

E.in order to make more precise measurements than it ever did, and scientists are hoping they will be able to

A 选项得 that scientists hope will enable 怎么解释啊
我选了E，相比较E没有什么错误啊

ogram

that scientists hope will enable实际上可以看成that， scientists hope， will enable

E选项有四个错误1.in order多余，to和in order to 在意思和用法上也有区别
2.it 指代不清，您也许认为it指代NEAR spacecraft，但实际上有可能这个NEAR spacecraft之前没有对Eros进行过measure，而是别的spacecraft对Eros进行measure，所以it没有指代对象
3.意思分裂。原句想说这个NEAR spacecraft ENABLE 科学家们understand...,E选项只是说科学家们希望如何如何，却没有明确表示科学家们是依靠NEAR spacecraft才达到understand的目的
4.are hoping用进行时态欠妥，hope就可以表示同样的意思

恩，讲得很细，其实E的那几个方面我也考虑过，比如in order to 必然没有to简洁，are hoping 也没有hope直接。但问题是A做题的时候真不理解啊，当然您那样把scientist hope看成插入语当然一目了然，但从来没遇到过。我开始把A理解成绝对错误，hope will enable……所以排除A了

顺便问下您，我做og，白勇的SC感觉挺有套路的，但GWD有时候就抓不到套路，一些法则也运用不到，请问下您做SC最重要的原则是什么，像您做题的时候按着什么思路呢~~~不胜感激

我想抢句话：这题是一道典型的 “嵌入式关系分句”！
参考OG12-118. The world wildlife fund has declared that global warming, a phenomenon most scientsts agree to be caused by human begings in burning fossil fuels, will create havoc among migratory birds by altering the enviroment in ways harmful to their habitats.

a) A phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
b) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
c) a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels
d) which most scientists agree on as phenomenon caused by human beings who burn fossil fuels,
e)    which most scientsts agree to be a phenomenon caused by fossil fuels burned by human beings

正确答案：c
查了很多贴（国内和国外），对C选项的解释都是半斤八两，看得我一头雾水！（为什么一个定语从句里有两个动词agree和is）

一个普遍的误读是：说most scientists agree 是插入语，虽然是没加逗号！（此解释绝对是误人子弟！！！）

今天我翻遍章振邦的《新编英语语法》（CD上有下载），在1193—1395页赫然发现一个语法词条——嵌入式关系分句，详解如下：

“有一种关系分句（即定语从句），它既是先行项的后置修饰语（即定语），同时又是另外一个分句结构的宾语（即宾语从句）”此分句结构就被嵌入在定语从句中，即嵌入式关系分句。

该书举例：In his breast-pocket he had a patch of scarlet, which i suppose was the paper cap serving as a handkerchief.

注意两点：1）从句which was the paper cap serving as a handkerchief 首先是 patch of scarlet的定语从句。

              2）从句which（patch of scarlet） was the paper cap serving as a handkerchief 也是i suppose 的宾语从句，即I suppose （that）the patch of scarlet was the paper cap serving as a handkerchief 。

综上所述，但一个定语从句同时是另一个主谓结构的宾语从句是，就可以写为嵌入式关系分句。
