    Bob and I live in the same building. His room is on the tenth floor, but mine is on the ninth floor.①他和蔼却粗心, 并且时常陷入困境。

Last Friday afternoon, the young man went to a wild island to spend his holiday with his friends. They swam in the river, went fishing, played the guitar. They had a good time. Three days later, they decided to come back to the bank. Unfortunately, their boat hit a rock and soon went down. They were all in danger. With a villager’s help, all of them were out of danger. They didn’t come back until midnight. The young man was too hungry and quite tired.②So he wished to get home as soon as possible. But the lift didn’t work. He had to walk upstairs. He stopped by my door and took out a key. Of course, he could not open the door. He tried it again and again, but failed. He became angry and shouted, “I’ll cut you down with a knife！”

The noise woke me up and I opened the door. I understood at once what was happening and said, “You are trying to open a wrong door, Bob.”

“Sorry, I can’t agree with you, Mike！” he shouted, “It’s my room. You have entered it by mistake！”
