托福阅读否定事实信息题其实可以看作是托福阅读事实信息题的一种“变种”，在考察对象上，它们都是针对托福阅读文章的细节内容出题;如果仅从题型特点看来，托福阅读否定事实信息题更加耗时，一般情况下可以看作是4个事实信息题的集合题，但是如果看分值，这类题目又不可能有这样的解题难度。所以，前程百利小编探究了这类题型的选项设置，希望可以从中发现这类题型解决的快捷方法。
例1：Spartina alterniflora, known as cordgrass, is a deciduous, perennial flowering plant native to the Atlantic coast and the Gulf Coast of the United States. It is the dominant native species of the lower salt marshes along these coasts, where it grows in the intertidal zone (the area covered by water some parts of the day and exposed others).
1. According to paragraph 1, each of the following is true of Spartina alrerniflora EXCEPT:
A. It rarely flowers in salt marshes.
B. It grows well in intertidal zones.
C. It is commonly referred to as cordgrass.
D. It occurs naturally along the Gulf Coast and the Atlantic coast of the United States.
解析：
段落分析：第一句，Spartina alterniflora的特点：known as cordgrass，deciduous，perennial flowering，native to the Atlantic coast and the Gulf Coast。第二句，dominant native species of the lower salt marshes，grows in the intertidal zone。
看选项A,” rarely flowers”和“perennial flowering”矛盾，正确;
选项B，“grows well in intertidal zones”和“grows in the intertidal zone”符合，排除;
选项C，“referred to as cordgrass”和“known as cordgrass”符合;
选项D和“native to the Atlantic coast and the Gulf Coast”符合。
本题目中:正选特点，全部是原文内容的同义替换，而且很明显;错误选项，和原文内容出现明显矛盾，正选设置在第一项。
例2：This mode of craft production favored the growth of self-governing and ideologically egalitarian craft guilds everywhere in the Middle Eastern city. These were essentially professional associations that provided for the mutual aid and protection of their members, and allowed for the maintenance of professional standards. The growth of independent guilds was furthered by the fact that surplus was not a result of domestic craft production but resulted primarily from international trading; the government left working people to govern themselves, much as shepherds of tribal confederacies were left alone by their leaders. In the multiplicity of small-scale local egalitarian or quasi-egalitarian organizations for fellowship, worship, and production that flourished in this laissez-faire environment, individuals could interact with one another within a community of harmony and ideological equality, following their own popularly elected leaders and governing themselves by shared consensus while minimizing distinctions of wealth and power.
According to paragraph 3, all of the following are true of the Middle Eastern craft guilds EXCEPT:
A. The guilds were created to support workers and to uphold principles of high-quality craft production
B. Each guild was very large and included members from a broad geographic area
C. The leaders of the guilds were chosen by popular vote
D. All guild members were treated as equals.
解析：因为段落较长，只能按照选项来定位。
选项A，support workers和uphold principles做关键词定位至第二句，原文的mutual aid and protection等于support workers，maintaneance of professional standards等于uphold principles，A选项表达正好是第二句的同义替换，排除;
选项B,geographic area原文没有对应点，正确;
选项C，vote做关键词定位至最后一句，排除;
选项D，equals做关键词定位至最后一句，排除。
本题目中:正选特点，都可以找到定位点，同样是同义替换;错误选项，无法定位，即原文并没有提及。正选设置在第二项。
根据以上的两题目分析，在托福阅读否定事实信息题中，大家可以看到两类正选的特征：和原文矛盾或者原文没有提及，相对应的，大家在做题时可以参考的方法是，一方面加快自己定位的速度，一方面对文章没有提及的内容有敏感的认知;同时，也要注意，选项设置顺序没有规律，以原文为主。
以上就是前程百利小编带来的托福阅读否定事实信息题的选项研究。希望考生可以在备考时多多总结，找到适合自己的答题方法。预祝大家托福考试取得好成绩!
