五、Think and write. 学校正在评选“环保小卫士”。请你想一想，写一份申请书，说明你平时在家里和学校是如何节约能源的。
I want to be a “Green Guard” because I try to save energy every day.

参考范文：
At home, I always turn off the lights when I leave a room. I don't leave the water running when I wash my hands. I often reuse the water that I wash rice with to water my mom's flowers.
At school, I always turn off the lights in the empty classroom in time. I never waste paper, and I use both sides of the paper when I do my homework. I also tell my classmates not to draw on the desks to save stationery. I hope I can be the "Green Guard" and I will keep trying to save more energy.

【分析】本题要求写一份申请成为“环保小卫士”的英文申请书，需说明在家和学校节约能源的具体做法。解题思路：1. 开头点明想成为“环保小卫士”的原因（题目已给出）；2. 分两部分阐述在家的节能行为（如随手关灯、关水龙头、重复利用水资源等）；3. 再说明在学校的节能行为（如及时关灯、双面用纸、不浪费文具等）；4. 结尾表达希望当选并坚持节约能源的愿望，确保内容贴合实际、语句通顺。
【解析】结合日常节约能源的实际行为，用规范的英语语句组织内容：先写在家的节能做法，再写学校的节能做法，最后表达当选的愿望。
