Tom was tired out, and he went to bed as soon as he reached home.

　　Suddenly it occurred to him that he had planned to do something that evening. As he could not remember what it was, he tossed and turned in his bed for a long time.

　　Finally the thing came to his mind, "My God, the original plan was to go to bed early!" he said depressingly.

　　汤姆很累，一到家就上床睡觉。

　　忽然，他想起原来晩上计划做一件事，可他想不起来是什么事，他辗转反侧了很长时间。

　　最后他突然想起来了，“上帝，原来我的计划就是早点儿上床睡觉!” 他颓丧地自言自语道。
