188. Is it difficult for you to get up in the morning? Do you sometimes oversleep? Are you often late for work or school? Yes? Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed will get you up in the morning! Here is how it works: The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music or other pleasant sounds. A few minutes later, a second recording plays. The second recording can be loud music or unpleasant sounds. If you don’t get up after the second recording, you’ll be sorry. A mechanical “foot” is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few more minutes. What! You’re still in bed! Slowly, the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical. You slide off the bed and onto the floor. You are awake and out of bed. Hiroyuki made his bed because he wanted to win a contest. He works for Honda Motor Company. Once every two years, Honda has a contest—the “All Honda Idea Contest”. In 1996 Hiroyuki won a prize for his bed. [共5题]
