大全830讨论及一点规律总结

830.The spraying of pesticides can be carefully planned, but accidents, weather conditions that could not be foreseen, and pilot errors often cause much larger deposits of spray than they had anticipated.
(A) weather conditions that could not be foreseen, and pilot errors often cause much larger deposits of spray than they had
(B) weather conditions that cannot be foreseen, and pilot errors often cause much larger deposits of spray than
(C) unforeseeable weather conditions, and pilot errors are the cause of much larger deposits of spray than they had
(D) weather conditions that are not foreseeable, and pilot errors often cause much larger deposits of spray than
(E) unforeseeable weather conditions, and pilot errors often cause much larger deposits of spray than they had

我在B和D中犹豫了很久，个人认为真正的GMAT考题不会在如此偏颇的地方考大家。对于选B还是选D有两种可能的解释

1, 原文中划线部分和B的用法是一样的，于是得出规律：在原文没有错的情况下不能将其改为一个等价的表述(如此题的D）

2,这里的but前后有平行, the spraying of pesticides can be carefully planned BUT.... weather condistions that cannot be foreseen

个人认为解释1更合理，不知大家看法如何？

谢谢

同意。而且情态动词不能随意删减或添加。这里忠于原文can。B更优。

而且。动词（foreseen）优于形容词（foreseeable）。也可以作为一个辅助依据检验。

多谢指点，我也才在LZM公理里发现了“原文划线部分有情态动词的时候正确选项也必须有该情态动词”

小心XDF的公理, 很多巳經不能apply....
