昨天晚上,我在里屋写作业,妈妈在一旁陪我。(交代时间、地点、人物等要素,合理。)忽然,我听见有人用钥匙“咔咔”开门的声音,接着厨房里传来一阵脚步声,(未见其人,先闻其声,为后文做铺垫。)我和妈妈都以为是爸爸回来了,就没有去搭理,我继续写作业。 Last night, I was homework in the back room, my mother was with me. (Explain the time, place, people and other elements, reasonable.) Suddenly, I heard someone use the key “Kaka” to open the door, then heard a burst of footsteps in the kitchen, (no one, first heard the sound, Paving the way for later.) Both my mother and I thought my father was back and there was no way to deal with it. I continued to write homework.
