A Strange “Letter”
My neighbour`s children love playing hide-and-seek (捉迷藏) as all children do, but no one expected that a game they played last week would be reported in the local newspaper (地方报纸)。
One afternoon, they were playing in the street just outside the postoffice. Young Lan, who is only five years old, found the perfect place to hide. His sister, Janet, had shut her eyes and was counting up to ten when Lan noticed that the small metal (金属的) door of the letter-box had been left open. The postman had just taken all the letters out and had gone into the post-office to see if there were any parcels (包裹).Lan climbed into the letter-box and pulled the door from the inside so hard that it locked. Soon realizing what he had done, he became very frightened and started crying. Meanwhile, Janet was looking for him everywhere but could not find him. It was lucky (幸运的) she happened to stop outside the letter-box and hear her brother`s cries. She immediately ran to tell the postman who hurried out to unlock (开锁) the metal door. Lan was now free, but he had had such a bad fright (惊吓) that he could not stop crying. The postman, however, soon found a way of making him laugh again. He told him that next time he wanted to hide in a letter-box, he should remember to stick a stamp on himself!
