三、无复选
这个特点使得我们可以大胆的运用排除法，因为选项一定多余题目，所以利用排除法很关键，其次我们就要了解其干扰项的特点：
1 段落的细节内容
2 段落没有提到的内容
如：
More and more women are now joining the paid labor force worldwide. They represent the majority of the workforce in all the sectors--- informal and flexible such as home working, temporary, low paid and so on. Even in countries which have low levels of women paid workers, such as Arab countries, employment is rising.
This Section is mainly about:
A the paid labor force
B women working part time
C more women in the labor force
D the rising female workers in Arab countries
A选项过于广泛，而段落中有限定词 women
B是此段落中没有提到的，D明显是其细节内容。所以在这段文字中通过skimming我们就可以得知答案应该是C。
综合上述特点，其重点在于归纳和总结的能力以及如何排除干扰项。考生们也要注意作大量的练习达到熟能生巧，方能在此题中取得高分。
