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……

Free admission to museums Nowadays, more and more museums are free to admission. I think this's beneficial to more people to visit museums, so that developing citizen's culture education（提高公民的文化素养）. But this method also brings some problems. Such as financial problem. People needn't pay for any tickets, so every cost is depend on donation and government. As increasing number of visitors, museums should keep in repair more often. Something worse, some collections have been stolen. So in my opinion, free admission to museum is a so wonderful measure for us, in this way, we can get knowledge of (see) more exhibitions, more rarities. But I think may be we should pay a little to entry museums, then it could help museums' financial（正常运营）, on the other hand, we will be more serious to visit museums.
