It makes no difference what you read or study if you can't remember it. You just waste your valuable time．小题1:  One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading．

Why does a clerk in a store go away when your reply to her offer to help is, “No, thank you．I'm just looking.”? Both you and she know that if you aren't sure what you want, you are not likely to find it．But suppose you say instead, “Yes, thank you．I want a pair of sun glasses.” She says, “Right this way, please”

 小题2:  If you choose a book, “just looking” for nothing in particular, you are likely to get just that--nothing．But if you do know what you want, you are almost sure to get it．Your reasons will vary; they will include reading or studying “to find out more about”, “to understand the reasons for” and “to find out how”．

 小题3:  Before you start to study, you say to yourself something like this, “I want to know why Stephen Vincent Benet happened to write about America”．Because you know why you are reading or studying, you relate the information to your purpose and remember it better．

小题4:  At least two important processes go on at the same time．As you read, you take in ideas rapidly and accurately. But at the same time you express your own ideas to

yourself as you react to what you read. You have a kind of mental conversation with the author．

This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes．小题5:  One part of critical reading, as you have discovered, is distinguishing between facts and opinions．Facts can be checked by evidence, opinions are one’s own personalreactions．Another part of critical reading is judging sources．Still another part is drawing accurate inferences．

A．Maybe you have already discovered some clever ways to keep yourself from forgetting．

B．It is important for students to have a positive attitude to their study．

C．You remember better when you know what you' re reading．

D．In other words, a good reader is a critical reader．E. It’s quite the same with your studying．

F. Reading is not one single activity．

G. This is the way it works．
