I think, I am misunderstanding Photoreading.
Before the pass question that I though step 3 is useless, I think Photoreading is just like search dictionary by purpose .
In fact , I did not understand what is Active. As the book describe step 4 can help me inhence my understanding level.
By the way , when I saw this description, I did not to realize that it is means that what I understand is come from the subconscious mind.
Now , sometimes , I fell tired to catch the key words in the book. There is too many key words. I fell weak to do that.
But during I catch key words , I find that I can understand somethings automatically. However , many key words did not associate my purpose.
