I go to school on foot every day. I live near the school, so I don’t need to take a car. Walking is good for my health and it helps the Earth. Cars make the air dirty, but walking does not. I feel happy when I see clean air and blue sky. I tell my friends to walk too. Small actions can make a big difference!
我每天步行去上学。我家离学校很近，所以不需要坐车。走路对我的健康有好处，也有助于保护地球。汽车会让空气变脏，但走路不会。当我看到干净的空气和蓝天时，我感到很开心。我也告诉我的朋友们一起走路。小小的行动也能带来大大的改变！
📖【重点词汇】 walk on foot（步行） clean air（干净的空气） make a big difference（带来很大改变）
📍【点评】这篇作文用词简单，句型重复清晰，适合小学生模仿。使用“I tell my friends...”这样的句子可以展示影响力，增强表达力。
Water is important for life. I try to save water every day. When I brush my teeth, I turn off the tap. I take short showers and tell my family to do the same. We only wash clothes when we have a full load. Saving water helps the Earth and saves money too. I feel proud to help protect our planet.
水对生命很重要。我每天都努力节约用水。刷牙时，我会关掉水龙头。我洗澡时间很短，并告诉家人也这样做。我们只有在衣服装满洗衣机时才洗。节约用水不仅帮助地球，还能省钱。我很自豪能为保护地球出一份力。
📖【重点词汇】 turn off the tap（关掉水龙头） take short showers（缩短洗澡时间） feel proud（感到自豪）
📍【点评】这篇作文贴近日常生活，使用“When I...”句型描述习惯，逻辑清晰。适合用来练习“日常行为”类写作。
In my home, we have three bins: one for paper, one for plastic, and one for food waste. I help my mom sort the garbage every day. Recycling helps the Earth because it saves resources. Old paper can become new paper. Plastic bottles can become clothes or bags. I also draw pictures to remind my classmates to recycle. I believe everyone can help the Earth in their own way. 我家有三个垃圾桶：一个放纸张，一个放塑料，一个放厨余垃圾。我每天帮妈妈分类垃圾。回收利用有助于地球，因为它能节约资源。旧纸张可以变成新纸张，塑料瓶可以变成衣服或袋子。我还画图画提醒同学们要回收。我相信每个人都可以用自己的方式帮助地球。
📖【重点词汇】 sort the garbage（垃圾分类） recycling（回收利用） save resources（节约资源）
📍【点评】使用具体例子（如塑料瓶变衣服）让作文更生动。结尾句“I believe...”提升文章立意，值得学习。
Last spring, I planted a small tree in my garden with my dad. We dug a hole, put the tree in, and gave it water. I take care of it every week. The tree gives oxygen and makes the air fresh. Birds come to live in it. I feel happy to help nature. I hope more children will plant trees too. Trees are friends of the Earth.
去年春天，我和爸爸在花园里种了一棵小树。我们挖了一个坑，把树放进去，然后浇水。我每周都照顾它。这棵树释放氧气，让空气变得清新。小鸟也来树上安家。我很高兴能帮助大自然。我希望更多的孩子也能种树。树是地球的朋友。
📖【重点词汇】 planted a tree（种树） give oxygen（释放氧气） take care of（照顾）
📍【点评】这篇作文使用时间顺序（last spring, every week）叙述事件，结构完整。动词如“dug, put, gave”都是小学阶段的重点动词，适合积累。
