One of the most powerful tools you can use to improve your reading comprehension is mind mapping. It is possible to create maps by simply using a pen and paper.
The first step is to draw a circle or box at the center of the page. Inside your shape write down the main idea that your mind map will focus upon. For example , if you were creating a mind map about the geography of the United States , then you would write down “the geography of the United States” in the middle of your page inside your circle.
Next you draw branches from your central idea. Much like a tree grows branches . Simply draw a line moving away from the central theme. In the case of the geography of the United States , you would probably draw 50 lines. Each line represents one of 50 states. These are the main categories(分类) with your primary concept（概念）.
Each of lines can then have branches off of each. These would represent the main example under each category. For example , under the line titled, “ Texas,” you would find lines called Austin, Houston, and Dallas, you might draw a series of lines to represent some of its main sections like “ South Dallas” and “ Highland Park” .
You continue to draw your mind map much like the structure of branches on a tree. Mind map helps improve your comprehension because they enable you to quickly see relationships between main ideas, categories , examples, and details that might otherwise be missed if you use more traditional note taking strategies(策略).
