四、Read and finish. Smith一家安装了智能电表，他们是怎么节约用电的？请你读一读，根据短文内容完成任务。
The Smith family's energy saving
The Smith family got a new smart meter(智能电表). It tells them how much electricity they use every hour. One day, they looked at the meter. It showed they used a lot of electricity from 6 to 9 o'clock in the evening. Why? Because they cooked dinner, watched TV, used the computer, and turned on all the lights at the same time. "We need to save energy," said Mr Smith. So everyone made small changes:
•Mrs Smith cooked dinner earlier.
•The children did their homework together in the living room with one light. They didn't turn on the lights in their own rooms.
•The family watched only one TV in the living room.
After one month, they checked the smart meter again. They used 20% less electricity! The Smiths were happy. They saved money and helped Earth.
任务一：完成下面的表格。
任务二：回答下面的问题。
What small change can you make at home to save electricity?

本题是英语阅读理解题，分为完成表格和开放性问答两部分。解题思路：1. 完成表格需根据每个问题，定位短文中对应的关键语句，提取匹配的信息；2. 开放性问答需结合短文提到的节约用电方法，联系自身实际，给出合理的节约用电小举措。
【解析】
任务一：1. 定位短文第一句“The Smith family got a new smart meter(智能电表).”，可知Smith一家得到的新东西是智能电表；2. 定位短文“It tells them how much electricity they use every hour.”，可知智能电表告知他们每小时的用电量；3. 定位短文“It showed they used a lot of electricity from 6 to 9 o'clock in the evening.”，可知他们用电多的时段是晚上6点到9点；4. 定位短文“The children did their homework together in the living room with one light.”，可知孩子们一起做的事；5. 定位短文“After one month... They used 20% less electricity!”，可知一个月后的结果。任务二：结合短文节约用电的方法，如随手关灯、用完电器拔插头等，给出合理答案即可。
