A
Xiaofan, a smart boy from Shenzhen, used to have difficulty in getting up on time, and his alarm clock was of no use at all. It made him very upset. One day, he had a good idea.
Xiaofan went to a shop and bought a tape. Back home, he started to record what he wanted. After that, he took out a tool box and connected his tape player with the new tape to his alarm clock. A special alarm clock was born. At a certain time in the morning, the tape player would play soft music with a low and sweet voice of a young girl, “Wake up, please.” Five minutes later, the tape player would play again, and it might be loud music. At the same time, he could hear a recording of his parent, “Wake up at once, or you’ll be late!”
Several days later, Xiaofan got used to the sound of the recordings. After the recordings, he was still sleepy, and even felt asleep again. That was terrible! So he went to the library and borrowed plenty of books home to deal with his problem of getting up late.
He made it! With the help of what he had learned from the books, he put a mechanical（机械的）arm at the end of the bed. Now if Xiaofan still doesn’t get up at last, the arm in the bed will “beat” him, and even make him out of the bed.
The special bed with a mechanical arm helps Xiaofan a lot, but it is not sold in stores.
