Plastic bag was once called as the most useful invention in the 20th century and it was disposable in our country in the past few years.
塑料袋被认为是第二十世纪最有用的发明，我国在过去的几年里就开始的一次性使用品。
However, in recent years, as the excessive use of plastic bag has brought a great pollution to our environment, our country has established and carried out a series of relevant regulations to limit the use of it. Since then most supermarkets have not provided free plastic bags when we are shopping.
然而，近年来，随着塑料袋的过度使用，给我们的环境带来了极大的污染，我国已建立并实施了一系列相关规定来限制它的使用。从那时起，在我们购物的时候许多超市不免费提供塑料袋了。
In my opinion, limiting the use of disposable plastic bags is a significant and meaningful measure or policy to decrease environmental pollution as well as save social resources. And it also illustrates that our nation have realized the importance of environmental protection. Hence, it is really necessary and important to keep carrying out this measure or policy so that our nation and even the whole world can achieve sustainable development.
在我看来，限制使用一次性塑料袋是一项用来降低环境污染并节省社会资源的重要的，有意义的措施或政策。这也说明，我们的国家已经意识到环境保护的重要性。因此，继续实施这一措施或政策是必要的和重要的，这样我们的国家乃至整个世界才可以实现可持续发展。
