标题: prep1-120 为什么要用would??

120.
(30859-!-item-!-188;#058&004335)

Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

(A) Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting

(B) Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects

(C) As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting

(D) As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject

(E) As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject

选E, 我好不容易理解了as is the case with...这种用法，但是为什么要用would呢？表示虚拟？？

是虚拟.

D除了逻辑上不对以外,语法上的错误是助动词省略形式不能被还原,后面的两个动词will和is都不能用would代替.

这道题我是看逻辑主语的。expand 和 ejet 这两个动作都应该是太阳发出的而不是hydrogen这种气体发出的。

楼上两位解释后还是觉得不明白为什么E要用would，如果是虚拟语气那应该是跟未来不可能实现的事实，可是，the case确实是可能成为事实的，为什么要用虚拟呢？

作者: aeoluseros 时间: 2008-9-5 01:13

好吧，记得白勇书上还说过can和could在gmat里只考时态区别

可是prep里确实看到了它们在语气上有区别的题目

所以我想这也算是个命题趋势，如果语气不是非常的肯定，那么也可以用would了...毕竟ets，gmac从来没说过它们认为can,could,will,would只有时态区别。

虽然还是这种不肯定的语气有点模糊，使用起来不知道会不会有歧义...

至少在will和would这点上是不足以排除选项的

would在这里是表推测吧，OG上有明确的提过推测时最好用would的

作者: dirrrk 时间: 2008-9-5 09:33

as is the case with...这种用法

怎么理解。。。

以下是引用aeoluseros在2008-9-4 23:25:00的发言：

我认为这道题是这样的，like得比较要对等，

所以只能用as is the case with...

而谓语would表示虚拟，这在GMAT里是没错的。

所以谓语比较合适的位置就是E,

排除掉明显是错的。

make sense. the thing confused me is prep grammar notes..

as be the case (with)...是不是一种固定搭配啊？

至于为什么用虚拟语气：太阳没有exhaust...,估计其他恒星也还没有报废，case是对未来的一种推测，所以用would。

这题正如ls所说：用排除法吧，唉唉～～

d 和e的解释不是不是有矛盾?

为什么d 用问would 错,而e就可以呢?

作者: grape262001 时间: 2009-2-4 12:43

ls,我支持你！

同问！

i think the would in d and e is right, the problem with d is it compares star and hydrogen

同问！！！另外d中的　　would为什么错，而e中确可以呢？？？

顶一个啊

虽然这题是E没错啦，但主要应该是在DE中选择然后用代词指代对象的逻辑选择E吧。。。

不过D中的as ... would单独看对吗？因为这在as的从句中只补出助动词would，没有would do（be)之类的，这样可以吗？

注：我问的是一般规律，不是这道题

谢谢~

up,问nn

d和e中的would问题

作者: ivyfeng 时间: 2009-10-1 11:36
ding!

问： 1 D中的as-clause结构对不对，是不是应该加上as....would do的结构。

2 E中的as-clause的正确顺序是：As the case with any star of similar mass would be ,
once the Sun exhausts the hydrogen in its core, it will expand into a red giant
and eventually eject。那个be后面没有同样形式的谓语， as表相似情况的主要原则之一不就是从句谓语和主句谓语形式一致么，还是这又是GMAC的一个”new lesson"

谢谢！

"As would be the case" is better than "as is the case" for this sentence because it refers to a hypothetical star of similar mass to the Sun's. If the sentence referred to a specific star to which this happened, then "as was the case" would be appropriate since the construction would refer to an actual event.

in choices C and D, "it" refers to "hydrogen" (the subject of the previous clause). This reference leads to the absurd idea that the _hydrogen_ will expand into a red giant AFTER IT'S ALL GONE. Choice C also exhibits a rather obvious parallelism defect, which also happens to be ungrammatical: "and eventually ejecting" not only fails to be parallel to "will expand," but is also, well, wrong.

Choice B is all kinds of wrong. Since "like any star of similar mass" doesn't have a subject, we need "the Sun" right after the comma (and it isn't there). Like choices C and D, this sentence mistakenly employs "it" to refer to hydrogen. And givemeanid has already pointed out the tense problem.
