At present most supermarkets is pursuingthe policy of charging for plastic bags instead of giving them free. This policy is carried out for controlling pollution since thepollution resulting from plastic bags has become a big threat to urbanenvironment. Though daily use of free bags in the markets is tremendous innumber, I don't think consumers' paying for plastic bags can take effect incontrolling pollution.

現今大部分的超市都推行塑料袋收費政策，不再提供免費塑料袋。這項政策的實施是為了控制環境污染，因為塑料袋造成的污染已經成為都市環境的一大威脅。然而日常人們使用的塑料袋數目巨大，我認為消費者為塑料袋買單并不能有效地控制環境污染。

 Tobegin with, it is unfair that only consumers should shoulder the responsibilityof environmental pollution caused by plastic bags, providing free plastic bagsto consumers is a marketing strategy adopted by supermarkets. Althoughsupermarkets have to pay for the plastic bags, consumers bring them far greatereconomic rewards in comparison to this minimal cost. From this point of view,it is the supermarkets that have gained the hidden profits through free bagswhile consumers only get shopping convenience they should have.

首先，只有消費者為塑料袋造成的環境污染承擔責任，這是不公平的，因為為消費者提供免費塑料袋是超市采取的一種營銷策略。盡管是超市購買的塑料袋，但是這項花費相比消費者為超市所帶來的回報來說是微不足道的。由此來看，超市一方通過免費塑料袋獲得了隱藏利潤，消費者只是享有他們應有的便利而已。

In addition, it is over-optimistic and bitsimple-minded to contend that charging for plastic bags can help reduce pollutioNPRoblem. My observation tells me that in most supermarketsplastic bags are offered by salespeople according to customers' actual needs. Since the need for shopping bags does exist, charging for those bags is not soeffective. Besides not only the supermarkets provide free plastic bags, mostthe food markets and shops do. Therefore it is unrealistic to expect thispolicy to help reduce the pollution problem caused by plastic bags.

其次，期望塑料袋收費政策起到減少其所帶來的環境污染問題，這樣的想法過于樂觀和簡單些了。通過親自觀察我發現，在大多數超市里收銀員都是根據客戶的實際需要來提供塑料袋的。如此消費者對塑料袋的需要一直存在，那么塑料袋收費根本沒有效果。此外，免費塑料袋不只有超市才提供，大部分的菜市場和商店都會為消費者提供免費塑料袋。因此，期望這個政策減少塑料造成的污染是不太現實的。

In short, it is not a wise policy to chargeshopping bags. To protect the environment, people should take varied ofeffective measures.

總之，購物塑料袋收費這一舉措并不明智。人們應該采取各種各樣的有效措施來保護環境。
