问题描述：
初中英语完形填空：Yesterday I was very tired when I came home from work.I （）while my one-year-old
son was playing with his toy.For a while ,a loud lock at the door woke me up.它的标准答案是was asleep,但是我觉得应该是fell asleep,因为从时间上来判断,其中有For a while这句话,如果是was asleep就在时间的开始上界限模糊,可是fell asleep则就可以判断“我”是什么时候睡着的,而was asleep配上for a while总觉得不知道是从什么时候开始For while（我醒来）.大家觉得怎么样呢?能给我个具体和理由么?
