Reading Selectively or Extensively？
Some people think when we read we should read selectively. That is to say， we should select some books we are interested in and ignore the others. Reading selectively can help us concentrate our limited time and attention on those selected books.
Others think we should read extensively. No matter what kind of book it is， we should look it over. We should read various kinds of books， whether we are interested in them or not. They maintain that reading extensively can help to enlarge our view and grasp the general knowledge in different fields.
In my opinion， the two reading ways have their roles respectively in our reading. However， the disadvantages of each methods are easy to see. If we only read the books we select or prefer， the framework of our knowledge may not be complete. Our knowledge would be rather limited. And if we read without selection， we may not have so much time and energy to be specialized in one particular field. Therefore， the combination of the two methods is more reasonable.
