　　大学英语四级考试作文题

　　For many years we have been using disposal plastic bags when we are shopping on the market, and most often these bags are offered by the shops for free. This, undoubtedly, has brought us great convenience in our daily life.

　　However, its disadvantages are also very apparent, and Ill just venture to explore two aspects. For one thing, the plastic bags are mostly indecomposable in the natural state so that with the increasing use of these bags, it will not only seriously bring about the so-called white pollution to the environment, it can also cost us a lot to have them decompose completely so as to minimize their damage to the environment. For another, the production of plastic bags are often not strictly supervised, so a large proportion of the bags dont meet the requirements for healthy products, which means the more we use them, the more likely we are to suffer in health.

　　The negative effects of the plastic bags are far serious than what Ive mentioned above, so its high time the government issued strict laws and measures to stop using the bags. By so doing, we can save a lot of money from producing these bags as well as return a cleaner earth to ourselves and the later generations.
