Many cities around the world today are heavily polluted. Products (产品) arc not produced in a "green" way and people haven't realized the importance of buying and using environmentally-friendly products. These lead to the pollution problem. One result is that millions of tons of waste like glass, paper and plastics is produced (生产). The waste problem is difficult to deal with.
However, today, more and more people are choosing “green” and expecting that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: “Will this soap be bad for the environment”“Can this metal container be reused or can it only be used once?”
Over 20,000 people took part in a web survey (调查) on buying environmentally-friendly products. Among them, 8129 people say that they now consider the environmental safety of a product before they buy it. That is to say, companies must change the way they make and sell their products to make sure that the products are “green”.
A few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels to show that they are green. Some companies have made the clean and safe products their main selling point in advertisements.
The growing need for a safer and cleaner environment is making companies rethink how they do business. The public will no longer accept the old idea of “buy it, use it, throw it away, and forget it”. As a result, the companies have to take action.
【小题1】Is it easy to deal with the waste problem?
【小题2】What do more and more people consider before they buy products?
【小题3】In the survey, how many people prefer green products in the supermarket now?
【小题4】Is it possible or impossible to get green products in the supermarket now?
【小题5】Why do the companies have to rethink how to do business and take action?

    ·Don't stand on chairs. Many people may fall off chairs and hurt themselves.

    ·Keep the floor dry, and you won't slip (滑) or fall.
