"Mike, I don't think you have as many friends as you think. I'm sure 2 of them are not real (真正的) friends. If I'm 3 , I'll buy you a big bag of chips."
"OK, but 4can I know they are real friends or not?"
"Well, here's a special 5 . You can't see it. But if you take it to school and 6 it successfully (成功地), you'll find the magic and know who7 real friends are."
Mike took the chair to school. He asked all his friends to stand around and he stood in the 8, with the chair. He said, "9move. I'll show you something amazing."
Then Mike tried sitting on the chair. Of course, he10down. Everyone had a good laugh. Luckily, he didn't hurt 11 . Mike made another try. But again, he failed.
Mike kept trying, and kept falling, until, suddenly (突然), he tried again and didn't fall.
12 , Mike smiled happily. He saw Judy, Lucas and Diana —13of his best friends —holding him up, 14 he didn't fall. Mike finally knew about the magic his grandfather talked about. Also, Judy, Lucas and Diana became his15 for life.
