The earth needs a helping hand
The earth is our home and it is in danger of being polluted. The earth is getting warmer because of the
1 of people. We
2 and bum trees and send gases into the air with our cars and factories. Can we do
anything about it? Sure. We may
3 be leaders or scientists but we can play our part in
4 the planet.
Here are two ideas.
Bike, do ride to school
Do you go to school by bus or by hike? If you bike, you are doing
5 for the earth.
Buses, cars, trains and planes produce a lot of carbon dioxide (二氧化碳). If you live near to your
school,
6 bike there on warm spring mornings?
7 , you can simply walk to school to save energy.
Wash in the green way
Do you often help your mom wash clothes? Then wash them
8 an energy-saving way.
A recent study by Cambridge University found
9 60% of the energy used on a piece of clothing is
10
in washing and drying it. Over its lifetime, a T-shirt can
11 up to 4 kilograms of carbon dioxide into the
air.
12 you wash your own clothes, wash them in cold or warm water to save energy, but not hot water. Wash your clothes when they fill up the machine. Use the most energy-saving machine you can find. Some
new ones use as
13 as one-fourth of the energy of older machines. When they're clean,
14 your clothes in the natural way, by hanging them on a line
15 putting them in a dryer. In all, you can cut the carbon
dioxide used in washing by 90%.
