Ⅰ. Writing a passage
请以“Save electricity”为题写一篇小短文。

Save electricity
Electricity is very important for us. We need it to work, study and live every day. But a lot of electricity is wasted in our daily life.
We can see some empty classrooms still have lights and air conditioners on when no one is inside. It's wrong to do that. We should turn off all the electric equipment when we leave the room. On bright sunny days, we don't need to turn on the lights at all. Our teachers also tell us saving electricity is a good habit.
Let's try our best to save electricity from small things!

这是一篇图画提示类命题作文，符合七年级英语写作的难度要求，写作时可遵循以下思路：
1. 开篇点明电在日常生活中的重要性，自然引出"节约用电"的写作主题；
2. 结合四幅图的提示内容：无人的空教室仍开着灯和空调、离开时随手关闭电灯电源、老师提醒学生节电、主动宣传节约用电，列举日常里简单可行的节电做法；
3. 结尾发出倡议，呼吁大家从小事做起，养成节约用电的好习惯，行文保证语句通顺，使用七年级已学的词汇和语法即可，字数控制在80词左右。
