Fashion isn't very environmentally-friendly because it makes people buy things they don't need, just because they're new. We want to take care of the environment, we don't want to pol­lute the air and we don't want to waste energy and resources. But we also want to be fashiona­ble. How can we buy fashionable clothes and protect the environment?
Old styles are fashionable again, so one way is to buy second-hand clothes — recycled clothes. Another way is to buy' fair trade clothes. These clothes are either recycled or made in a ' way that protects the environment. They also protect the people who make the clothes.
Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To pro­tect the cotton, the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as hemp and bamboo, grow quickly and are more environmental­ly-friendly. These materials are very soft, and look fantastic. The best materials are coloured using natural dyes, made from plants.
Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes that are also environmentally-friendly.

A Simple Scientific Experiment

Below is a description of a single scientific experiment. It shows us how iron reacts ( 反应) with air and with water.
Aim : To find out if iron rusts( 生锈) (a) in dry air ; (b) in water that has no air in it ( air- free water) ; (c) in ordinary water.
Materials : 3 clean iron nails ( 铁钉) ; test tubes ; test tube holder ; cotton wool ; oil ; Bunsen burner.
Iron in dry air
Method
(1)Put some iron nails at the bottom of a test tube.
(2)Push some cotton wool down the tube.
(3)Leave the tube for one week.
Result
After one week, the nails have not rusted.
Conclusion
Iron does not rust in dry air.
Iron in air-free water
Method
(1)Half-fill a test tube with water.
(2)Boil the water for three minutes. (This makes sure there is no air in the water.
(3)Put two or three clean nails in the water.
(4)Add some oil to the water. (This will keep air out of the water.)
(5) Leave the tube for one week.
Result
The nails do not rust in the tube with air-free water.
Conclusion
Iron does not rust in air- free water.
Iron in ordinary water
Method
(1)Half –fill a test tube with water and add two or three clean nails.
(2)Leave the tube for one week.
Result
The nails rust in the tube with ordinary water.
Conclusion
Iron rusts in ordinary water. (238 words)
【小题1】In the first part of the experiment the cotton wool is most probably used to ______________.
A.keep the air dryB.keep the tube wet
C.make the nails rustD.keep the tube clean
【小题2】What are necessary steps to make sure the water in the tube is air free?
①Leave half a tube of water in it              
②Boil the water for some time
