Q27:

Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide and, if it strikes Earth, it can do tremendous damage to part of the planet but probably not cause planetwide destruction.

and, if it strikes Earth, it can do tremendous damage to part of the planet but

and, if it would strike Earth, part of the planet could experience a tremendous amount of damage but it would

and that, if it were to strike Earth, could do tremendous damage to part of the planet but would

and that, if Earth is struck by it, can do part of the planet tremendous damage, but it would

and that, if it strikes Earth, it could experience a tremendous amount of damage but

答案是C

但是be to不是在GMAT里禁用吗？

为什么不选择E？

Were to, would 是虚拟语气的用法，陈述不可能发生的事实

running

E中it多余

E. if it strikes earth, it could experience damage

第二个 it 指代谁呢? asteroid 还是 earth?  所以不选 E.

以下是引用joe11在2005-12-18 15:13:00的发言：

E. if it strikes earth, it could experience damage

第二个 it 指代谁呢? asteroid 还是 earth?  所以不选 E.

既然第一个 IT指代的是 asteroid 那摸　第二个ＩＴ　就一样指代　asteroid

一个句子的同一个代词只能只带同意个东西

我觉得选A,理由是：

1、that在这里并不是并列从句的标志，第一个that指代 an asteroid,第二个则没有任何指代（如果C正确的话），不符合平行的原则，或者说这样的话，and后面不需要加that。请注意原句并不是 point
        that clause and that clause 的形式。

2、有一般现在时表示自然规律，比如地球绕太阳运行---asteroid撞到地球，就会造成damage。我觉得也是合理的，不是一定要用虚拟语气。

我也觉得选a，c的那个that没有必要吧。

选a的话没有办法和前面的that is平行了，so我认为A错

tsuki

但我觉得虚拟语气里的过去时有问题……不是说if A do，B will do；if A did， B would do么？而且可能发生的不是不用过去时咩？
