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.

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

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

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

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

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

这题我选E，答案是C，请教一下虚拟语气可以用could来表示吗? 用would应该意思上更确切罢，请NN们指教。多谢

老实说, 这题顶怪的:

首先(A)(B)不对称, 就可以先排除掉

(D)被动表达不好, 排除

(C)的if从句用了过去式, 表与现在事实不符; 用were to strike表将来动作的意味

(请见stoneren解说)

could可以用于虚拟；E的错误关键在于虽然其用了一个形似平行的that结构，但两个that在各自的从句中所作成分不同，以至这个看似的平行其实是不平行结构，前一个that引导定从，在从句中作主语，后一个that在其引导的句子中不知道作什么成分，因为从句的主语it已经十分清楚了；所以，E这个答案最大的trick就在于平行结构的引导词的作用，这个问题希望能够得以重视，因为现在的考试中经常会遇到类似的问题。

多谢楼上两位的解释了。我太粗心了，要不是Stoneren版主指点，我还没有发现那个该死的it。Thanks a  lot

偶怎么觉得A对啊？！

两个分句并列。

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.

(A)在这里的感觉后面的it多余了, 因为and是连接that从句共用that从句的主语;

如果是照你说的, 应该要在and前面再加个逗号, 而不是后面, 使得与that从句的关系断掉, 并重新与本句主句连接起来

另外 A没有表达出应有的虚拟 这是绝对不可以的

horsefish

同意C.

E的错误是由于it造成是asteroid could experience a tremendous amount of damage,而不是地球遭到重创.

This point makes sense to me. Thanks! Vincent.

Agree on C although I reluctantly chose A when I did this test because I thought C is lacking of subject, which is totally wrong. !
