    【题目】 Things You Can Do To Help The Environment.

    The biggest use of home energy is for cooling and heating. So turn up your air conditioner and turn down the heat, especially at night.

    Replace regular light bulbs with fluorescent bulbs (荧光灯), which use less energy.

    Cars are getting bigger, even 5 meters long. They burn more gas and increase problems with acid rain and air pollution. So try to walk, bicycle, or use public transportation. This can save more gas and reduce pollution.

    Each American throws away an average (平均)of 10 kilograms of trash every day. Reduce waste before you buy by thinking it carefully: Do I need it? Is it something I can only use once? Buy products that you can use over and over again.

    Showers use a lot of water. In one week, a typical American family uses as much water as a person drinks in 3 years! Buy a special “low-flow” showerhead or take shorter showers. This can cut water use in half.
