第三，学会排除干扰选项

四级干扰选项明显的特点有以下几点：

一是文章选项无。所谓文章选项无就是给出的选项，文章中作者根本没有提到。

二是答案本身错。所谓答案本身错就是给出的选项本身就是错误的。

三是张冠李戴。所谓张冠李戴是最能干扰考生的。就是明明是说A的偏偏要说B。考生由于读文章不仔细，乍一看选项是自己所熟悉的，并且是文章中出现过的。于是便毫不犹豫地选了它，殊不知是错误的。举例：

①Is there enough oil beneath the Arctic National Wildlife Refuge(保护区)（ANWR）to help secure America’s energy future? President Bush certainly thinks so.He has argued that tapping ANWR’s oil would help ease California’s electricity crisis and provide a major boost to the country’s energy independence. But no one knows for sure how much crude oil lies buried beneath the frozen earth. With the last government survey, conducted in 1998, protecting output anywhere from 3 billion to 16 billion barrels.

1. What does President Bush think of tapping oil in ANWR?

A. It will exhaust the nation’s oil reserves.  B. It will help secure the future of ANWR.

C. It will help reduce the nation’s oil imports.D. It will increase America’s energy consumption.

对于这个问题，很多同学选择了答案B。原因是他们根据文中第一段第一句话（黑体划线处）毫不犹豫选择B。殊不知原文第一句话，特别是阴影标记出说的是“缓解美国未来能源危机”。而答案B说的是缓解ANWR未来的能源危机。属于张冠李戴。这类选项是应该引起考生高度注意和重视的。
