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

答案是A,我没有明白答案的句子结构。to make more..measurements that ....??

请指教！

再顶！

AlienX

scientists hope是插入
拿走會比較好懂

那结构是make measurements will的结构吗？make sb do sth

sophiaruan

我觉得是 scientists hope 是插入语，

不是结构make measurements will？也不是make sb do sth，

而是make +adj+n...

that修饰n，引导定语从句，that作主语，不能省略。

measurements that will enable sb to do sth.

不对请指出

楼上的解释感觉有道理，但是插入语前后可以没有逗号吗？

这种语法结构看到好几个了,都没弄明白怎么回事.

根据你的说法,是不是应该这样看:

measurements that, scientists hope, will enable them (指代scientists) to XXOO...

yes
太短的插入短語, 很多時候都不enclosed by commas

A选项them指代有问题，语法上指代measurements，但是逻辑上指代scientists，这个错误太明显了。谁能解释一下？

语法上不可能指代scientists，就如AlienX班班说的一样，scientists hope是插入语，可以省略不看。

为什么插入语的内容就不能被指代呢?

所谓的可以不看, 只是说它不是句子主干而已, 可没说它不是句子的一部分啊.
