Week 1 This week, my family tried to save electricity. We never left the lights on when leaving the rooms. We switched off the TV when $\underline{n\ 1}$ was watching it. Mum only used cold water in the $\underline{w\ 2}$ machine.
Week 2 We started recycling this week. We tried to write on $\underline{b\ 3}$ sides of our paper, not just on one side. We also divided our rubbish into $\underline{d\ 4}$ bags for bottles, cans, paper and food. Mum kept the plastic shopping bags from the supermarket to use them $\underline{a\ 5}$ as rubbish bags. These are great ways to help our environment.
Week 3 We stopped taking long baths and had short showers $\underline{i\ 6}$. We flushed the toilet with used water. When Mum and Dad made tea or coffee, they used $\underline{l\ 7}$ water in the kettle(水壶). My sister and I didn't leave the tap running when we brushed our teeth.
Week 4 Mum used to $\underline{d\ 8}$ us to school, but now my sister and I have started riding our bikes to school. It's hard work but good exercise! This week Dad and a few of the people he works with also started to go to work together in one car and $\underline{s\ 9}$ the cost. This should help $\underline{r\ 10}$ greenhouse gases!
My friends and I became volunteers at school. We help make our school more earth-friendly.
