Let’s Talk! 參考答案P. 142

How do you save resources?

(1) Water is necessary and valuable in people’s daily lives. I use two ways to save this resource. First, the water that my mom uses to clean vegetables or fruit can be reused to water the plants that I grow. Second, our dishwater is reused to flush the toilets in our home. Overall, reusing water is my method to reduce the amount of water that is wasted and save this valuable resource.

(2) I persuaded my family to switch from conventional vehicles to electric ones. Since oil will be used up in 40 to 50 years, to utilize alternative energy is essential. Moreover, electricity­driven vehicles are more environmentally friendly because they don’t emit any exhaust gas. Making less noise is also one of their biggest advantages as it helps reduce noise pollution. With the technical progress and the development of scientific knowledge, we all need to re­evaluate the necessity of keeping consuming oil.
