Things You Can Do to Protect the Environment
CARS
Cars are getting bigger. SUVs — large, truck - like vehicles — are now the most popular cars in the United States. Bigger vehicles burn more gas and increase problems with acid rain and air pollution. So try to walk, ride a bicycle, or use public transportation. And if you drive a car, keep it in a good state. This can save gas and reduce pollution.
ENERGY
The biggest use of home energy is for heating and cooling. So turn up your air conditioner and turn down the heat, especially at night. Replace regular light bulbs with fluorescent bulbs, which use less energy. And remember to turn the lights off.
PRODUCTS
Each American throws away an average of 10 kilograms of rubbish every day. Most of that trash goes into landfills. Reduce waste before you buy by asking yourself: Do I need the item? Is it something I can use only once? Buy products that you can use over and over again. If you use disposable(一次性的) products, choose those made from recycled materials.
WATER
Showers use a lot of water. In one week, a typical American family uses as much water as a person drinks in three years! Buy a special “low - flow” showerhead or take shorter showers. This can cut water use in half. Also, fix any leaky(渗漏的) taps.
A. Where do you think the article is from? Tick the right answer.
□ A dictionary. □ A magazine. □ A novel.
*B. Read the statements below. Then choose the advice from the passage that each person should follow.
1. Statement: Jason always takes long showers in the morning.
Advice: ______
2. Statement: In winter, Jessica keeps the heat on all day.
Advice: ______
3. Statement: Kevin drives to work, but his office is near his home.
Advice: ______
4. Statement: Annie leaves the lights on at home all the time.
Advice: ______
