五、阅读理解
In the USA, a question is asked millions of times every day in the supermarket: “Paper or plastic(塑料的)？” Well, which kind of bag would you choose
In fact, all kinds of bags have some effects on the environment. But we are always told that paper bags are better. For example, they break down(分解) easily and can be recycled(再利用). However, making paper bags takes more energy than making plastic bags. How can this be true
Studies show that paper bag production needs four times as much energy as plastic bag production. And the amount(数量) of water used to make paper bags is twenty times higher. And the effect on forests is more serious. It takes about fourteen million trees to produce ten billion paper bags. As for recycling, some people believe that paper bags are more environment-friendly than plastic ones. However, this idea can be quickly discarded. Research shows the opposite is true.
Even though paper bags may be more harmful than plastic ones, plastic still seems to be regarded by governments as the more harmful of the two. In Ireland, people have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.
It seems wise to reuse these bags. However, we're not doing that a lot. That may be because they are easily broken. If so, cloth(布) bags are a better choice, but still their production also has a bad effect on the environment. So what should we do How should we answer the question of “Paper or plastic？” It seems that we first need to ask ourselves the following question: “What can I do to help the environment？”
