GWD-11-Q33
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 E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
网上只对A和E两个选项争论非常大, 其他的比较好排除
老师的解释:
I would choose A because it's cleaner. By that I mean it is the jet engine that could propel aircraft.... E requires the insertion of "and it" ... words that are not needed, as well as "capability to" a phrase that is not needed. Besides, it is more correct to use "of and ...ing" rather than "to" with capability. We make no distinction between people and things when we use the word "capability." The word "that" in A actually refers to "type" rather than "of jet engine." As we discussed in class, prepositional phrases (只的是after那句)are sort of like "throwaways" in grammar because nothing has to "agree" with them in terms of gender or number.
Does any of this make sense. I think it's a tough question. I'm not even sure I'm right. In fact, I think both options have their problems in terms of clarity and "cleanness" of expression. |
