Question

【题目】

How do you deal with plastic bags from the supermarket? Throw them away or recycle them? How about eating them?

The bags are no harmful to the environment. Humans and animals can safely eat them. Indian company EnviGreen has made a bag with natural materials. It looks and feels just like plastic ,but can be broken down(分解) easily.

Ashwath Hedge who set up the EnviGreen company spent four years doing experiments(实验) with 12 natural materials. They include potato, corn, vegetable oil and banana. He made the materials into liquid and used the liquid to make the bag.

Although the EnviGreen bag is more expensive than a common plastic bag, it has many advantages .According to the Wall street Journal, it takes 1000 years for common plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview: he put an EnviGreen bag in water and ate it with a smile.

There are more than 15,000 tons of plastic waste in India every day. But only 9,000 tons are processed. In China, 3 billion plastic bags are used every day. Maybe EnviGreen bag could be a solution(解决办法)to the world problem of plastic pollution.

【解析】

本文是一篇说明文，传统的塑料袋对环境影响太大，文章介绍了一种可以食用并迅速分解的环保袋的发明过程，这种环保袋可以帮助我们解决塑料污染的问题

【1】细节理解题。根据第二段第一句The bags are no harmful to the environment.可知D项说法是错误的，其余三项都是这种新型的环保袋的特点。故D项正确。

【2】段落大意题。在第三段里作者告诉我们花了4年时间，做了无数的实验，用12种可以食用的自然材料做成了这种环保袋。也就是说本段主要是关于Hedge制作环保袋的过程。故B项正确。

【3】推理判断题。本句“Hedge was happy to show it in his interview: he put an EnviGreen bag in water and ate it with a smile.”告诉我们Hedge把这种环保袋放入水里并笑着把它吃掉。Hedge这样做是告诉人们这种环保袋是安全的。故A项正确。

【4】细节理解题。根据第四段第四句It also breaks down in less than a day in water, and in less than a minute in boiling water.可知这种环保袋在水里一天内可以分解，在热水里1分钟内就可以分解。也就是说在热水里这种环保袋更容易分解。故C项正确。

【5】判断推理题。文章告诉我们这种环保袋是由可食用的材料做成的，而且很容易分解。最后一句Maybe EnviGreen bag could be a solution(解决办法)to the world problem of plastic pollution.告诉我们可以用这种环保袋帮助我们解决塑料污染的问题。故D项正确。
