 The Earth is getting warmer because of the activities of people. We cut down and burn trees and send gases into the air with our cars and factories. 1 Sure. We may not be leaders or scientists but we can play our part in protecting 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 something for the Earth. Buses, cars,trains and planes produce a lot of carbon dioxide. If you live near to your school, why not bike there on warm spring mornings? 2

Wash the green way

Do you help your mom and dad wash clothes? Then wash them in an energy-saving way. When you wash clothes, wash them in cold or warm water to save energy ， but not hot water. Wash your clothes when they fill up the machine. 3 Some new ones use as less as one-fourth of the energy of older machines.

When the clothes are clean, dry them in the natural way, by hanging them on a line rather than (而不是)putting them in a dryer.

 4 For example ， you can use it to clean the floor,water flowers, trees and so on. In all,you can cut the carbon dioxide used in washing by 90 percent.

5 If everyone pays attention to protecting the environment from himself,our earth will become more beautiful.
阅读上面短文，把A—E五个句子填人文中空，处，使短文内容完整，通顺。

A.Can we do anything about it?

B.The Earth needs a helping hand.

C.Besides, the water that you have used can be reused to do many other things.

D.Or,you can simply walk to school to save energy.

E.Use the most energy-saving (节肯旨的) machine you can find.

 People drive their vehicles through lovely cows ，which is a traditional Indian sight. However, India's cows are not very lovely.

  In India ， there are nearly 485 million animals ， and half of them are cows. Cows work much more to global warming (全球变暖)than vehicles. Why? Because they produce a great number of CH4—a greenhouse gas,and it causes 20 times more heat than C02. But can Indians kill cows to solve the problem? Certainly not. As the world's largest producer of milk,India will still have to increase the dairy (乳品业)production to keep up with its growing population. So cows play an important role in the life.

   Scientists are designing diets to help cows eat better. In this way ， they will make unpleasant gas less. But most Indian farmers can only afford to buy poor food for their cows. So many farmers adding herbs (草药)to the food now. The herbs are cheap and they can produce less CH4. And the cows don't seem to mind the taste.

Besides, quite a few projects are going on. One of them is biogas production — cows' waste is used as energy in kitchens and vehicles. It helps stop global warming.
