一个星期六,妈妈比平时起得都早,匆匆地吃过早饭就下楼了,我问妈妈去干什么,她也不说。我想:“妈妈今天不上班呀?她去干什么了呢?”第二天,妈妈依旧起得很早,还是匆匆忙忙地吃完饭就下楼了。我决定一探究竟,跟踪追击。妈妈下了楼,我也悄悄地跟在后面出了门。妈妈走过一条街,又穿过一条马路,然后拐进了一栋很破旧的楼房里。 One Saturday morning, my mother got up earlier than usual and hurriedly eaten breakfast downstairs. I asked my mom what she did, and she said no. I thought, “Mom does not go to work today? What does she do?” The next day, Mom still started up early, or hurriedly finished eating downstairs. I decided to find out, tracking chase. Mom went downstairs, I also quietly behind the door. Mom walks through a street, crosses a street, and turns into a very old building.
