Sample Text Completion Questions 段落完型样题

答题指令：请在每个空格相应的栏目中选取能最好完善短文的备选答案。

1. It is rreshing to read a book about our planet by an author who does not allow facts to be (1)__________ by politics: well aware of the political disputes about the fects of human activities on climate and biodiversity, this author does not permit them to (2)__________ his comprehensive description of what we know about our biosphere. He emphasizes the enormous gaps in our knowledge, the sparseness of our observations, and the (3)__________, calling attention to the many aspects of planetary evolution that must be better understood bore we can accurately diagnose the condition of our planet.

Answer: overshadowed, obscure, and superficiality of our theories

第一空线索：

读某本书能带来rreshing效果，则表明这本书作者写作的效果就是有让我们rreshing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“rreshing”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。

第三空线索：

实际上是三个并列重复，同时和一个分词构成手段和目的重复。

He emphasizes the enormous gaps in our knowledge, the sparseness of our observations, and the (3)__________, calling attention to the many aspects of planetary evolution that must be better understood

即：

the enormous gaps in our knowledge,

=the sparseness of our observations,

=（and） the (3)__________,

=calling attention to the many aspects of planetary evolution that must be better understood

可以推断空格应该填写一个负面评价。

Directions: For each blank select one entry from the corresponding column of choices. Fill all blanks in the way that best completes the text.
