Thomas was a good student but he didn't respect others. One day，his aunt gave him a1as a birthday gift. He went around the classroom playing his drum. When others asked him to keep 2or play somewhere else，Thomas refused.
Thomas's classmates couldn't 3the noisy drum，so they stopped playing with him. Joe, one of his classmates，invented special earplugs (耳塞)which allowed people to hear normal sounds, but stopped the bad ones. Thomas got very4with Joe. He even had a big fight with Joe.
A few days later，a clock was put into the classroom，just next to the desk of Thomas. The clock was making the5like “Tick tock, tick tock.” Thomas couldn't concentrate on his study at all.6 ， the others，with their special earplugs，were OK. Soon Thomas started to 7how much he had disturbed his classmates with the drum，and how silly it had been to fight with Joe. In order to change the situation，Thomas decided to say8to his classmates. What's more，he9played his drum in the classroom. Seeing Thomas's great changes，his classmates10forgave (原谅)him and decided to play with him again. From then on，Thomas changed a lot and got along well with his classmates.
