阅读理解。 I have a seven-year-old son named John. He loves chocolates. He often takes chocolates instead of meals. Therefore, he gets very bad teeth. The dentist (牙医) told me not to let him eat chocolates any more. But his grandfather dotes on (宠爱) him. He often buys John chocolates even though he knows that they are bad for teeth. I know that John is his only grandson, who is everything to him. I really don't want to make him unhappy. Therefore, I always allow John to eat the chocolate his grandfather bought him. Yesterday evening I kissed John good night and asked him to say his prayers before going to bed, and then I left his bedroom. A few minutes later, I heard John shouting word by word. 'Tomorrow-is-my-birthday. May-God-bring-me-a-big-box-of-chocolates.' I went to his room and saw him kneeling on the ground shouting out his prayers. I said, 'Don't shout, John. Your Dad is sleeping now! God can hear you no matter how softly you talk to him.' Pointing to the next room where his grandpa sleeps, John said secretly, 'My God is sleeping. He can't hear me unless I wake him up.' 1. Why does John's grandpa often buy John chocolates? [     ] A. He doesn't know they are bad for his teeth B. He loves John very much C.
