Answer choices for question 1.
Answer: overshadowed,obscure, andsuperficiality of our theories
第一空线索：
读某本书能带来refreshing效果，则表明这本书作者写作的效果就是有让我们refreshing的效果或者预期。所以，他“does not allow facts to be (1)__________ by politics”不会让政治“politics”对这本书作什么作用呢？当然是不会让政治使其破坏这本书“refreshing”的特点。则，第一空从正负就可以将illuminated排除。具体选择“overshadowed”“invalidated”还要参看第二空。
第二空线索：
第二空线索说作者不允许them怎样。往前寻找them指代，很容易发现：them就是politics。这样一来，马上可以看到这样的重复：
an author who does not allow facts to be (1)__________ by politics
= this author does not permit them to (2)__________
都是说作者不允许政治对书做怎样的动作。则两空是同义重复。又由于第一空推出动作是负面的。故两空都是负面的。则第二空是obscure, 而第一空也就只能是overshadow。英语作文
