小题1:Holly: How I miss the clear water and fresh air in my childhood! But everything has changed, that is, the clear water and fresh air are nowhere to be found again as they were. Above all, a great deal of waste hardly rots(腐烂) away.

小题2:Jimmy: More and more people are beginning to have a good knowledge of the

importance of a safer and cleaner environment, which in turn forces the business to be cleaned up.

小题3:Samantha: Organic products(有机产品) are getting more and more popular among people, but we should know the fact that organic products might also do harm to our health in some way.

小题4:Patria: I’m very much fond of growing some vegetables of my own in my small garden, for many vegetables on sale in markets are actually becoming more and more dangerous as a result of widespread pesticides(农药).

小题5:Derrick: Nowadays it is very convenient for consumers to find and buy green food in supermarkets as they are clearly marked.

A．"Organic produce is always better, "Gold said．"The food is free of pesticides, and you are generally supporting family farms instead of large farms．And it is tastier."

B．Market research shows that small amounts of pesticides can be used on organic products．And about three quarters of organic food in Britain is not local but imported(进口) to meet the need.

C．Many cities around the world today are heavily polluted. Careless ways of production and lack of consumer demand for environment-friendly(环保) products have made pollution problem more serious. Millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.

D．However, today, more and more consumers are choosing "green" and care about the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: "Will this shampoo be bad for the environment?" "Can this be reused or can it only be used once?"E．Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds．Some supermarket products carry labels(标签) to show that the product is green．Some companies have emphasized it in their advertising that their products are clean and safe enough for people.

F．The concern for a safer and cleaner environment is making companies rethink how they do business．No longer will the public accept the old attitude of "Buy it, use it, throw it away, and forget it." The public pressure is on, and gradually business is cleaning up its act.
