晚上睡前,我照例仔细地整理书包,准备明天上学用的东西。摸到衣服口袋时,咦,钥匙没有了。我一阵奇怪,怎么搞的?钥匙哪里去了?我把柜子、书包、抽屉都翻了个底朝天,可还是没找到。我急死了,头上热了起来,背上也出汗了。我一步步回忆起来:放学回来是我自己开门进来的,钥匙就在衣服口袋里。会不会忘记拔下来了?应该不会,不然爸爸、妈妈会发现的。那怎么会不见了呢? At night before going to bed, as usual, I carefully tidy up my bag and get ready for school tomorrow. When I touched the pocket of my clothes, I did not have the key. I was a strange, how to engage in? The key where to go? I put the cabinets, bags, drawers are turned over to the sky, but still could not find. I was in a hurry, my head was hot and my back sweated. I recalled it step by step: coming back from school is my own door open, the key is in the clothes pocket. Will not forget to unplug? Should not, otherwise, my father, mother will find. Then why is it gone?
