Dennis stared at his grandpa's bookshelves. There were a lot of books on them. "Have you read all of these?" Dennis asked. Grandpa smiled. He heard this question many times. "Most of them, yes." "What are they all about?" "Oh, there are all kinds of books." Grandpa pointed to the wall near the window. "Those ones there are reference books (工具书). You could learn things about fixing or identifying (识别) birds from them. I like to know a lot of things about nature and how to do things."
Then Grandpa pointed to the left wall, "These ones are all science fiction (科幻小说), including a few I wrote." "You wrote books?!" Dennis was surprised. He knew Grandpa read a lot, but had no idea his grandpa was also a writer.
Dennis then turned to the right wall. "What are these ones?" "Fantasy books," Grandpa answered. "Isn't fantasy almost the same as science fiction, because they're both make-believe?" "Not exactly, because science fiction is based on real life. It's something that could happen someday. Fantasy, on the other hand, is all pure make-believe, which will never and was never true. It's great fun to read!"
"Can I read one of them?" Dennis asked. Grandpa smiled and picked one.
"I thought you'd ask, so I had already chosen one before you came. And you can read more if you take care of it." Dennis took the book from Grandpa's hands. "I'll start it right now," he said, but his stomach growled (咕咕叫). "Or maybe I can start after lunch." They both laughed.
