When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very    21   . Some stories are told   22   they were true. Real people who live in a  23  world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not   24   . They are characters and creatures that are very different from us and do things that would be   25  for us.

But there is more to books and writing than this. If we think about it, even realistic writing is only   26   . How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter ,we  2 7   seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than   28   . Reading, like writing, is an action. It is a way of   29   . When we read or write something ,we do much more than simple look at words on a page. We use our   30    --which is real—and our imagination—which is real in a different way --- to make the words come to life in our minds.

Both realism and fantasy(幻想)    31   the imagination and the “magic” of reading and writing to make us think. When we read    32  realistic, we have to imagine that the people we are reading about are just like us, even though we   33   that we are real and they are  34  . It sounds   35   ,but it works. When we read, we fill in missing information and   36   about the causes and effects of what a character does. We help the writer by   37   that what we read is like real life. In a way, we are writing the book, too.

Most of us probably don’t think about what is going on in our   38   when we are reading. We pick up a book and lose   39   in a good story, eager to find out what will happen next. Knowing how we feel   40   we read can help us become better readers, and it will help us discover more about the real magic of books.
