The third unit of Grade 7 English focuses on daily activities and time expressions. Here's a structured 1000-word essay following the requirements:

（段落1：周末家庭活动）

Last weekend, my family and I planned a special outdoor adventure. At 8:00 a.m., we packed picnic baskets containing sandwiches, fruits, and drinks. My father set up the tent while my mother prepared fresh lemonade. I helped my younger brother put on his hiking shoes. The sun was shining brightly as we drove to Green Lake Park, located 15 kilometers away.

（段落2：公园观察自然）

Upon arrival, we chose a grassy area near the lake. My father taught us to identify different types of trees through a field guide. We noticed swallows flying in V-shaped formations and children playing kites on the hill. I observed a family feeding ducks using bread crusts while my brother tried to catch fireflies with a jar. The air smelled sweet from blooming jasmine plants.

（段落3：团队游戏挑战）

At 11:00 a.m., we joined a group of other families for team games. The competition included three rounds: relay races, water balloon tosses, and knowledge quizzes about local wildlife. Our team won the first race by 20 seconds through perfect coordination. During the second round, my mother accurately identified 8 out of 10 local bird species. The final quiz tested our memory of seasonal changes in the park.

（段落4：午餐时光）

At 1:30 p.m., we had our picnic lunch. My brother accidentally dropped his juice box but quickly picked it up. We shared stories about our school lives - I told about our English drama practice last Friday, while my sister mentioned the science experiment on Monday. The lunch became a time to strengthen family bonds through conversations about school projects and weekend plans.

（段落5：环保意识培养）

While eating, we discussed environmental protection. My father explained how plastic waste affects wildlife, showing photos of marine animals harmed by pollution. We decided to start a "Green周末" project at home - recycling paper, separating trash, and planting trees. My brother suggested creating a school poster campaign, which we all agreed to support.

（段落6：学习新技能）

At 3:00 p.m., we visited the park's art studio. An elderly artist taught us basic watercolor techniques. I tried painting a sunset scene but mixed colors too brightly. My father helped me adjust the composition, showing me how to balance light and dark areas. We created small paintings of park scenery, which will be displayed in our classroom.

（段落7：运动时间）

Afterwards, we played badminton near the lake. My mother served 32 serves without missing a single one, which I found amazing. My brother developed a new serve technique by observing seagulls flying over the water. We played until our arms felt tired but laughed whenever someone made a funny shot. The physical activity helped us build better coordination and teamwork skills.

（段落8：返程感悟）

At 5:30 p.m., we packed up our belongings. The journey home gave us time to reflect on the day. My father mentioned how family activities strengthen relationships, while my mother talked about the importance of outdoor education. I realized that weekends shouldn't just be about playing games but also learning through experiences. My brother fell asleep in the backseat, his face glowing from the sun's warmth.

（段落9：日常应用）

On Monday morning, we applied what we learned. In English class, I shared my weekend experiences using present continuous tense: "We were playing badminton when..." The teacher praised our creative expressions. During science class, we discussed how plants adapt to different weather conditions, relating it to our observation of park flora. My brother even won a drawing contest with his firefly jar sketch.

（段落10：持续实践）

Since then, we've made weekends more meaningful. Every Saturday morning, we do community service - cleaning public parks, feeding stray animals, and assisting elderly neighbors. We've also established a family journal to record weekly achievements and challenges. My English vocabulary has increased by 45 new terms related to nature and activities. Most importantly, we've become closer as a family through shared experiences.

（段落11：未来计划）

Looking ahead, we plan to participate in the school's "Weekend Adventure" program next month. The schedule includes mountain climbing, camping, and cultural site visits. I want to improve my English presentation skills by preparing a 3-minute report about our weekend activities. My brother aims to master basic badminton strokes, while my parents hope to learn photography together. We believe these activities will help us grow both individually and as a family unit.

（段落12：总结升华）

This weekend experience taught me that meaningful weekends combine fun, learning, and family bonding. Through outdoor activities, we discovered nature's beauty, practiced useful skills, and strengthened our relationships. The lessons learned extend beyond weekends - they become part of our daily lives. I've realized that true education happens not only in classrooms but also through hands-on experiences and family interactions. As we continue our "Green周末" project, I'm confident that our family will create more unforgettable memories together.
