Q6:

After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.

A.
tested that could eventually propel aircraft anywhere in the world within two hours or help

B.
tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help

C.
tested, eventually able to propel aircraft anywhere in the world within two hours, or helping

D.
tested, and it eventually could propel aircraft anywhere in the world within two hours or helping

E.
tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
Answer: E

the answer is E, but i think A is more clear and concise

here, capability means a talent or ability that has potential for development or use: i think it is not logical in this sentence~

please help me. 3ks

这里capability不是主要问题，从句前必须补个it，因为前面是a new type，而只有engine才能propel aircraft。分清动作的主语哦。所以ABC首先排除了。

soudisiga～～～～

i thought"it" refers to "a new type"

according to your evaluation, "it" should refer to the nearest noun——engine??

3ks a lot!!!

Yes! "it" refers to engine

作者: chengzhiying 时间: 2010-7-15 21:59

为什么it可以指engin，不能指type呢？

it同样指代不清啊？

这是争议题，我觉得选A

我觉得it 指的是type还是engine应该不是问题的关键

我想问问lower costs than current methods permit，这个than后面的current methods

permit是个什么结构？

我个人也认为A比较简洁，并且意思也正确

首先，根据help的形式就排除了B,C,E

我之所以认为A正确是因为，我觉得可以把A看成是“为了避免头重脚轻而将定语从句后置的语法现象”

不知道牛牛如何解释~~~~~·
