Season 1——manhattan 12(moon was formed from)(已结贴）

12. Some scientists suggest the moon had been formed out of part of the Earth, which was dislodged perhaps by ameteor.
        A       the moon had been formed out of part ofthe Earth, which was dislodged perhaps
        B       that the moon was formed from part of theEarth that had perhaps been dislodged
        C       that part of the Earth formed the moon,which was dislodged perhaps
        D      the moon was formed out of part of theEarth, having perhaps been dislodged
        E       that the moon had been formed from partof the Earth, which perhaps had been dislodged

一开始有些没什么头绪。。。
从语义判断，a,b,e的which/that都指earth，和后面所说的dislodged by a meteor逻辑有问题，留下CD
D有问题，逗号+having been dislodged用法wordy。
所以选C

支持选C
B里面定语从句修饰prat of the Earth还是the Earth太混淆了。
感觉had been dislodged时态也不是很好。
用主动语态能够更有效的表达原句的意思

A,D,E就不用说了，重点是选B，还是C。
认为，was dislodged，被驱逐的，是part of the earth，但是这个part of the earth=moon，选项B中that引导的限制性定语从句紧跟the earth，所以是修饰part还是the earth很模糊；C中的which引导的非限制性定语从句修饰的就是moon，意味着其实也就是修饰part of the earth，从这点来说，相对于选项B就显得更为准确。

再加上GMAT考试中主动优于被动，以及B中比较莫名的过去完成时态，削弱了选项B是为正确答案的可能性，

所以，选C，+1。

AE的which指代不明确，就近指代的是earth
C的which指代的是moon
D的having主语省略，但承前省略的话应该是moon而不是parts of earth


应该选B，句子没有歧义且简洁

本句意思是， 一些科学家认为月亮以前是地球的一部分，是被一个流星撞出去的。以前有个阅读JJ讲了月亮形成的3种理论，这就是其中一种。

考点：修饰，时态。

首先本句要解决一个大的问题，就是时态的问题，然后才轮到修饰。想一想，到底是先地球的一部分成为了月亮，还是先被甩出去了？应该是先甩出去，再形成月亮，不然月亮只能是地球的一部分，就没有形成之说了。

得出结论：甩出去用过去完成时，形成用一般过去时，才能很好的表明先后关系。

A  suggest 跟从句，that不能省。

B  正确。 part of the Earth that 。A of B that修饰，根据句意，这里修饰part。

C 甩出去应该用过去完成时，表明先后。

D suggest 跟从句，that不能省。

E 前后都用过去完成时错误。

c，没答案公布的？

B:  The lock suggests that she was forced to stay in the 2nd floor of the house that had been built by her father ???
C:  The lock suggests that she was forced to stay in the 2nd floor of the house, which was built by her father ???

哪句话更对咩？？？house和floor分别被谁修饰捏？？？
非限定性定语从句，和 限定性定语从句，此处是啥区别捏？？？

B.  Some scientists suggest that the moon was formed from part of the Earth that had perhaps been dislodged by ameteor.

可不可以改写成：B.  Some scientists suggest that the moon was formed from part of the Earth dislodged by ameteor ？？？

这两个句子呢（只考虑语法，不考虑科学实际的话）：
Some scientists suggest that the planet BBB was formed from moon  that had perhaps been dislodged from Earth by ameteor ？？？
Some scientists suggest that the planet BBB was formed from moon, which was dislodged from Earth by ameteor ？？？


自己乱想头大中......

语法上两句话都对，用that和which都对，修饰的都是house，只是两句话表达的含义不同。
用that表示附近有很多幢房子，而其中一幢是她爹建的。
用which就没有这个意思。
如果细看，B选项呢“that had been ”是累赘的。
C选项呢，which was built by her father这句话属于另一个意群，逻辑上不应该做前面分句的从句，不过放一下也没错，只是觉得有些啰嗦。

如果只考虑语法是可以的。
SC中的话perhaps要通过从句表现出来，所以还是需要用从句(as you knew)。

可以的，本来就是可以说moon被dislodged的。只是manhattan12的原题里，that had been dislodged修饰part比修饰moon更好（但都不错），而SC里面是选最好的。一定要建立优选思维哦（不过优选思维也一定要建立在逻辑分析的基础上）。
