在托福考试里面细节题又叫做事实信息题，这种题目的逻辑性很强，而且每次都必考。
下面我们就说说如何用数学思维做事实信息题。
首先这一类题型一定是每次考试一定会考的，平均每篇会出现大概3-5题左右。
需要学生有的快速阅读定位能力和精读相关句子的能力，所以也就是说既需要学生有快速的泛读能力，也考察学生的句子分析能力。
这类题目的题干通常是以这样的形式出现的：
■According to the paragraph, which of the following is true of X?
■ The author’s description of X mentions which of the following?
■According to the paragraph, X occurs because…
■According to the paragraph, X did Y because...
■ According to the paragraph, why did X do Y?
发现小规律了吗？
做题时我们可以试试以下的步骤:
■ 阅读题干，找定位词(关键词)
■ 根据题干中的关键词回原文中定位
■ 精读定位词所在句子。（通常1－2句话）通常线读定位词所在的句子，然后读其下一句，如没有，就读其上一句，依此类推。
■ 正确选项为原文的同意替换项或者与原文一致
■ 题干－> 原文 －> 选项
比如我们来举个例子：
■ Paragraph 4: Another major discovery was made in Egypt in 1989. Several skeletons of another early whale, Basilosaurus, were found in sediments left by the Tethys Sea and now exposed in the Sahara desert. This whale lived around 40 million years ago, 12 million years after Pakicetus. Many incomplete skeletons were found but they included, for the first time in an archaeocyte, a complete hind leg that features a foot with three tiny toes. Such legs would have been far too small to have supported the 50-foot-long Basilosaurus on land. Basilosaurus was undoubtedly a fully marine whale with possibly nonfunctional, or vestigial, hind legs.
The hind leg of Basilosaurus was a significant find because it showed that Basilosaurus
■ Lived later than Ambulocetus natans
■ Lived at the same time as Pakicetus
■ Was able to swim well
■ Could not have walked on land.
根据题干定位词: the hind leg of Basilosaurus,快速定位到原文倒数第二句。
精读之后发现并没有提到题干中所需要解答的问题的答案。然后我们来看下一句。下一句说是这样的脚太小了，无法支撑它在陆地上。显然也并没有答出题目的意思。
于是根据规则，我们继续往下看一句。
下一句原话是说这个剑龙无疑是一条完全海生的鲸鱼，后腿可能无功能或者残留。A fully marine whal就是答案里面的could not have walked on land的同义替换。
所以这道题选D。
做事实信息题的时候也一定要考虑定位词怎么找，因为定位词也可能被同义替换。
