【分析】首先明确写作身份为文昌中学八年级学生，需围绕“帮父母做家务”的活动展开，紧扣三个提示要点：一是说明做家务的起因（班级开展相关活动，决定周末给父母惊喜）；二是具体叙述做的家务（如整理卧室、扫地、洗碗、煮面等）；三是描述父母的反应及个人感受，同时注意使用一般过去时，词数不少于80，语言通顺连贯。
【解析】以第一人称视角，采用一般过去时写作：开头点明身份与活动起因，引出周末做家务的决定；中间详细列举做家务的具体过程，内容具体；结尾写父母的反应（兴奋并表扬）及自身感受（虽累但开心，体会到父母的辛苦），确保所有提示要点齐全，符合英语写作规范。
【答案】Helping Parents Do Housework
I am a Grade 8 student from Wenchang Middle School. Last week, our class held an activity called "Helping Parents Do Housework", so I decided to give my parents a big surprise at the weekend.
Last Saturday, when my parents went to work, I started to do housework. First I tidied up my bedroom and made the bed. Then I swept the floor and cleaned the living room. After that, I washed all the used bowls and plates. I even cooked simple tomato and egg noodles for our dinner.
When my parents came back home, they felt very excited and praised me a lot. I felt a little tired but really happy. I learned that it is not easy for my parents to finish all the housework every day, and I will help them share more housework later.
