接下来看一下TPO10Lecture3中的一道题目：

　　原文：You're right to guess that phosphorus can end up in Earth's atmosphere.

　　It can move from the land or from the oceans to the atmosphere,and vice versa.,

　　However, there's just not a substantial amount of in there,like there is with nitrogen.

　　It's a very minimal quantity.

　　题目：What comparison does the professor make involving phosphorus and nitrogen ?

　　A. Sediment on the ocean floor contains more nitrogen than phosphorus

　　B. The atmosphere contains more nitrogen than phosphorus

　　C. Nitrogen requires more time to get recycled than phosphorus does.

　　D.Phosphorus is more important than nigrogen to the development of fish.

　　解析：

　　1.原文处atmosphere 原词重复两次，因此为重点信息需要提取出来

　　2.转折信号词however后面通过同义改写：not substantial ; minimal quantity 引出了“少”这一核心意思，因此我们判定“少”为该出题意群核心考点

　　3.所以该出题意群核心重要信息为：atmosphere和少这个概念，对应到B选项

       再来看一篇今年3月3日出现的一篇真题文章

　　原文：

　　1.there is an implied triangle

　　2.formed by the woman on the left ,the flat iron building in the centerand the bowl of fruit on the right

　　3.three corners

　　题目：

　　How does Hassam unite the images in his painting The Breakfast Room Winter Morning?

　　A.Byplacing them to suggest the presence of a geometric shape

　　B.Byincluding natural objects from the outdoors in an indoor setting

　　解析：

　　原文用triangle和three corners重复三角这一核心概念，我们因此判定三角是该意群核心出题点

　　三角形与正确选项中的几何图形是由具体到抽象的同义改写
