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.
