The minute I sat down（我坐下的那一刻） in front of the TV, my mom came over（过来）. “Could you please take the dog for a walk（遛狗）?” she asked. “Could I watch one show first?” I asked. “No!” she replied angrily. “You watch TV all the time and never help out around the house! I can't work all day and do housework all evening.” “Well, I work all day at school, too! I'm just as tired as（一样累） you are!” I shouted back. My mom did not say anything and walked away. For one week（持续一周）, she did not do any housework and neither did I（”我也没做“，是倒装句的否定形式，否定用neither，肯定用so）. Finally, I could not find a clean dish or a clean shirt. The next day, my mom came home from work to find the house clean and tidy. “What happened?” she asked in surprise. “I'm so sorry, Mom.
