The Earth is getting warmer because of the activities of people. We cut down and burn 61 and send gases into the air with our cars and factories. Can we do anything about it? Sure. We may not be leaders or scientists but we can play our part in 62 the planet. Here are two ideas.

Bike, don’t ride to school

Do you go to school by bus or by bike? If you bike, you are doing 63 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, 64 not bike there on warm spring mornings? Or, you can simply walk to school to save energy.

Wash the green way

Do you help your mom and dad wash clothes? Then wash them in an energy-saving way. A recent study by Cambridge University found 65 60 percent of the energy used on a piece of clothing is 66 in washing and drying it. Over its lifetime, a T-shirt can send up to 4 kilograms of carbon dioxide into the air.

67 you wash your own clothes, wash them in cold or warm water to save energy, but not hot water. Wash your clothes when 68 fill up the machine. Use the most energy-saving machine you can find. Some new ones use as 69 as one-fourth of the energy of older machines. When they’re clean, dry 70clothes the natural way, by hanging them on a line rather than putting them in a dryer. In all, you can cut the carbon dioxide used in washing by 90 percent.
