A homework. 麻烦好心人帮忙改一下 Until recently, disposable plastic bags are used widely. No matter in supermacket or in restore shop, disposable plastic bags are provided. Almost people would lifts severy disposable plastic bags after going shopping. We must acknowledge that these bags are usable and convenient. It seems that we can't leave them in our lives. But it is a pity that disposable plastic bags would pollute the environment. It's called " white pollution". By contrast, paper bags may be more friendly to environment than plastic bags. For this reason, a provision(regulation) is launched about it. The use of disposable plastic bags are limited. Others may disagree, but I believe that this measure is acceptable, because it will be more beneficial than harmful for environment. 谢谢啦……
