　　4.Excused from recycling because you live in a high rise with a rubbish chute (垃圾道)? You won’t be for long. Miami’s Mark Shantzis has made it simple for those living in tall buildings to use the chute and cycle, too.

　　In Shantzis’ Hi-Rise Recycling system, a chute leads to a pip-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables ,glass, plastics, paper, metal, and other rubbish to go into separate boxes.

　　The system is controlled from a board foxed next to the chute door. The board has a button for each class of recycling materials. At the press of a button, a microcomputer locks all other floors’ chute doors and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the non-recyclables.

　　Sorting(分類) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tones of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective.

　　The purpose in writing this text is _________.

　　A to encourage people to recycle their rubbish.

　　B to introduce a recycling system for high rises

　　C to describe the use of computer technology in recycling

　　D to explain the need for rubbish collection in high rise

　　5 Many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment-friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastics, and these are difficult to get rid of.

　　However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these, “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”

　　A recent study showed that two out of five adults now consider the environmental safety of a product before they buy it, this means that companies must now changed the way they make and sell their products to make sure that they are “green”, that is, friendly to the environment.

　　Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels (標(biāo)簽) to show that the product is green. Some companies have made the manufacturing (生產(chǎn)) of clean and safe products their main selling point and emphasize it in their advertising.

　　The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the pubic 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.

　　What would be the best title for the text?

　　a. Business and People

　　b. Business Goes Green

　　c. Shopping Habits Are Changing

　　d. Supermarkets and Green Products
