终于豁然开朗了,原来是定语从句后置
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
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
这道题问了一个很N很N的人说选E，他说A的that 后面的东西不能修饰句子的主语，不知道大家有什么看法？开始我也选A
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
capability of?
the definition of capability ?
seems the " capability" cannot be used by "jet engine"...please check OG
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
楼主，这个可是很N，很N，很N的人噢
你肯定这是个很N的人?
我同意这位很N很N很N的同志的意见，选E. 觉得A不对。could eventually have the capability顶多只是罗嗦，但a结构有问题。我也说不出为什么。明天问问老外再来答复。
坚决不同意这个很n很n的人！如果单看的话，could就比have the capability好，更何况还是重复罗嗦。从选择频率上看could就比have the capability高！
我觉得A结构完全没有问题，人家只是从句长，放在后面平衡结构！！！这不是很平常的吗？要是按正常语序，大家更看不懂is being tested是做什么的了
这里的THAT引导的从句做主语的定语(当主句为系表结构时,主语定语通常后置);
而E我认为没有必要加and it@@@@@
欢迎指点!
仍在AE之间徘徊。
gonna be crazy
A or E ? which is correct ?
up~up
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
中的could 和have the capability to ……在意思上有重复，都是“能够”
我认为比较而言A对，如果主语从句很长，that是不是可以引导主语从句放在主句的后面？根据以往的经验，我觉得ETS在这方面比较灵活
首先，A选项 中，that引导的定语从句，不仅可以认为是为了句子平衡而后置（否则，类似的句子如果真需要限定性从句修饰时，将从句放在那里呢？难道放在主语后面？虎头蛇尾！）；
其次，因为是被动语态，其实A中的THAT从句还可以看作是原来主动语态的宾语从句，当主动语态变为被动语态时，只是将宾语前移为主语。而从句在不引起歧义的情况下，可以不移。
在此，在jet engine 和that 从句之间，没有其他的名词，所以，减少了歧义的可能。
综上，支持选项A(E的问题很多，NN门已经指出，不再赘述)
支持A，that后的修饰太长，所以放在being tested后。杨鹏的难句中就很多例子。
E有用词重复
E显然是不对的。
could 和have the capability 语义重复了
看来今年的考生对can和be able的重复这一考点吃的很透啊！
这绝对是本题考点。
A的定语从句后置也是考点。所以选A。
GMAT的许多题目其实就是ETS和大家的博奕，如果看到了ETS的居心，我们也就确定了一道题的答案。反倒不必在此类题目上过多纠缠和讨论语法。因为有争议时的所谓语法，其实也不过是ETS的语法。而ETS语法不过是承载其博奕动机的手段。
这题老管给的答案是 E，
而 的张嘉给的答案是A。
E有2个 毛病 1 。and it could 中的“it”多余，
2。could , capability 意思重复。
我也同意A。
可是有哪位XDJM能指出 B 的毛病？
B 错在哪里？
to淡蓝色的回忆
1、could 和have the capability重复，（同E）
2、or to help没有平行对象
应该是Ｅ
因为 that引出的是同位语从局，需要有主语，而A没有，所以错．大家都以为是定语从句了．
欢迎指点
that引导的定语从句跳过is being tested~~~修饰a new type of jet engine~~~~
这里定语从句没有紧跟先行词是可以的~~~因为不会引起歧义~~~is being tested都不是名词~~~所以跳过他们修饰最近滴名词~~~~OG
支持A
E肯定不对拉~~~could和capability语义重复了嘛~~~~这种错误og里面似乎是不能容忍滴~?
支持A
support A
E 的 could 与capability 重复一定错
that引导的定语从句跳过is being tested~~~修饰a new type of jet engine~~~~
这里定语从句没有紧跟先行词是可以的~~~因为不会引起歧义~~~is being tested都不是名词~~~所以跳过他们修饰最近滴名词~~~~OG
支持A
MM能够告诉我是OG的哪道题的解释说定语从句可以跳跃修饰的吗？谢谢！
同志们好,我同意E.
A语法有问题啊!
宾语从句的主语在哪??!!
没有啊!!
另外propel 与help平行
终于豁然开朗了,原来是定语从句后置
还是不太明朗，
还是公说公有理 婆说婆有理。。。。
我在A和E之间犹豫，
A确实是that从句没有 紧跟 被修饰的 jet engine
而E似乎也是有点儿 太罗嗦了。
要是不考这题就好了。
终于豁然开朗了,原来是定语从句后置
agree
同意A
开始选A
看了讨论觉得E至少没有比A更严重的错误。
A中的that 应该修饰主语中心词- a new type 这显然是不合句子的逻辑意思。句子的逻辑意思that应修饰 jet engine.
如果考试遇到，我回选E。尽管E也不很完美。
支持A
若为A,that的作用若为引导宾语从句，该句缺主语;that 若是引导定语从句，该句前面没有先行词，that无所指，
E在避免上述问题的同时，做到了parallal的原则
必然是E
可惜o记解释不止一次说明了定语从句的引导词that和which一定要紧跟先行词呢
XDF的老师总结也如是说
could have capability中的could不是实意动词。这里的核心动词是ｈａｖｅ与句尾的ｈｅｌｐ对应。我觉得不能认为是can be able to这样意义上的重复。
另外，我们一直在说，GMAT的语法是ETS自己的语法规则，但做题是否找出薄冰语法中的在OG和其它真题中从未出现的定语从句后置来说明问题，我感觉有些不太对。
根本上应该从逻辑意思上考虑,引擎应该eventually推的飞行器２小时内到处飞，还是应该eventually有了２小时内到处飞的能力？我向E更加复合逻辑意思
我认为A不能仅以语法考虑（THAT主语从句应该也是可以）。关键在于这两句话的意思不同。第一句THAT从句代表主语的属性，整个话的意思是“一个可以。。。的飞机发动机被检测。而E的意思是说一个发动机被检测，并最终证明了它能。。。。所以从句意看肯定是E更好。---一位NN曾经说过~~~~
SO E~~~~~~~~~~~~~~~~~~~!!!
Correct：“I put the
cake that I baked by the door”Incorrect：“I put the cake by the door
that I baked．”
我觉得这题和上面举的例子不同，例子里的从句跟在door后，会引起从句修饰door的歧义，而33题中没有这个问题。
请指正，谢谢！
一个国外的网站上说OA是E。不知道OA是什么。official answer？

看来that不能放在谓语之后是更为严重的错误。
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
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
这道题问了一个很N很N的人说选E，他说A的that 后面的东西不能修饰句子的主语，不知道大家有什么看法？开始我也选A
== 首先，很显然不能用定语从句that ...。排除 A/B
== C中eventually able to ... is a fragment
== E正确。it 指代清晰，to propel ... or (to) help boost ...形成并列都是作the capability的补语。
同意选E.
A中that引导限制性定语从句,但没有紧跟其修饰的词.
E虽然有罗索的嫌疑,但个人认为比起A来还是要好一些.
看来还需要继续讨论...
我觉得 要仔细体会 it could eventually have the capability to propel aircraft anywhere in the world within two hours or help的意思, 是指有这个能力,虽然我做的时候选了A,但是还是E对,仔细想过后
支持E
A中eventually修饰propel,而题目要表达的不是这种 new type of jet engine是一种能够最终propel的engine，而是能够最终有了这种propel 的能力,即could eventually have the capability to propel, 选E
someone find this, I support A
A中的could是can的过去时态.时态不对吧.请指正.
本题A虽然读起来不爽，但是没有致命错误，个人意见：
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.其中的is being tested是倒装，因为that从句的修饰部分太长了，所以is being tested提前了。
E的致命错误除了could和have ability重复之外，capability的用法是，capability of doing，没有to do的用法，这个是肯定了，相信所有的语法书里都是一样的。
所以，E绝对不能是答案。
A is best
right!!!!!!
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
个人认为应该是E。A里面的that说不通，既不是定语从句（与修饰的东西隔得太远）也不是先行词，（因为没有主语）。所以句子读起来总觉得缺了什么。E 罗嗦了点，但是语法没有问题，句意也算有理。这里的could和capability不是同一个意思，应该不是句意重复。
赞同A，是定语从句后置修饰，E中can和capability明显重复
为什么很多人纠结说A是定语从句后置。。。定语从句不都是后置的吗？好像只有定语后置一说吧？
A的焦点问题是隔开了is being tested，前面有个mm举的CNN例子是something being tested that...，我觉得这个例子还是有区别的，因为being tested是个修饰成分，is being tested是个谓语结构，好像OG里没出现过隔开谓语结构再修饰主语的定语从句，如有请指正！

为避免“头重脚轻”而采用的倒装形式，杨鹏GRE难句里面一大堆都是这种句子，还有比这个看上去更离谱的

太牛了，这都能看出来
