Everyone has experienced trying, but failing to master a difficult book that was begun with the hope of increasing one's understanding. When that happens, it is  ____ 36  to think that it was a mistake to try to read it, but that was not the mistake. The mistake was in  ____ 37  too much from the first reading of a(n)  ____ 38  book. If you read it in the right way, no book written for the  ____ 39  reader, no matter how difficult, need be a cause for despair(令人失望). What is the right method? The  ____ 40  is an important and helpful rule of reading that is either not  ____ 41  or often forgotten. That rule is simply this: when reading a difficult book for the first time, read it through without ever  42  to think about the things that you do not understand immediately. Do not be stopped by what you  ____ 43  understand. Read through the difficult  ____ 44  ,and you soon come to things that you do understand. Read these  ____ 45  .You will have a much better chance of understanding all of the book when you read it again, but that  ____ 46  you to have read the book through once  ____ 47  . What you understand by reading the book through to the  ____ 48  will help you when you try later to read the places that you did not  ____ 49  in your first reading. Or if you never re-read the book, understanding half of it is much better than understanding  ____ 50  of it, which will happen  ____ 51  you allow yourself to be stopped by the first difficult part of the book. Most of us were taught to  ____ 52  the things that we do not understand. We were told to find the  ____ 53  of unfamiliar words, and to try to find an explanation in another  ____ 54  for anything that we did not understand in the book that we were reading. But when these things are done before the proper time, they only  ____ 55  our reading, instead of helping it. 36. A. necessary     B. useful C. natural       D. effective 37.
