D-SAT阅读核心：

难句信息提取与逻辑理解系列

机考SAT句子的阅读重心是核心信息提取与逻辑理解，而非简单机械从语法角度提取主干，虽然提取主干是必经过程与辅助方法。

核心信息提取与主干划分的区别，在于服务文本还是服务于自我认知。

这里可以给大家看两个句子，一个是提取长难句，一个是服务于自我认知所产生的理解差别，从而大家可以感受纯粹提取主干跟真正理解长难句有什么不同：

长难句：

The fate of the country does not depend on how you vote at the polls-the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot-box once a year, but on what kind of man you drop from your chamber into the street every morning.

主干版本：

The fate of the country does not depend on how you vote at the polls-the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot-box once a year, but on what kind of man you drop from your chamber into the street every morning.

学生会把句子主语和出现过的谓语全部标记出来。然后宾从的部分全部画起来，或者里面挑一些字，或者甚至留白。

自我认知版本：

The fate of the country does not depend on how you vote at the polls-the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot-box once a year, but on what kind of man you drop from your chamber into the street every morning.

1.depend on-因果关系

2.因：street

3.结：fate

4.自我认知：老百姓决定国家命运。

“老百姓”这个语义绝对不是翻译“street”出来的。
