Now people are very concerned about the food problem. Steve Wilson prefers organic fruit, delivered right to the doorstep. He is willing to pay for it. If this is not possible, the 30-year-old computer technician will spend the extra money at the supermarket to buy organic food.
“Organic product is always better,” Wilson said. “The food is free of pesticides(农药), and you are generally supporting family farms instead of large farms. And more often than not that it is locally grown and seasonal, so it is more tasty.” Wilson is one of the growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic product? Market research shows that Wilson and others who buy organic food can generally give clear reasons for their preferences—but their knowledge of organic food is far from complete. For example, 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 growing demand. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market,” said Sue Flock, a specialist in this line of business.
1.Why does Steve Wilson prefer organic fruit?
A. It is delivered right lo the doorstep.
B. More and more people buy organic fruit.
C. He likes home-grown fruit very much.
D. He considers the fruit free of pollution.
2.What does the underlined words “the organic trend” in Paragraph 2 mean?
A. Getting the food anywhere.
B. Growing food at home.
C. Better quality of organic food.
D. Growing interest in organic food.
3.Why does Sue Flock say it is a very fast-growing market?
A. Because of a rapid increase in the demand for it.
B. Because it is produced on large farms.
C. Because it can’t be produced on family farms.
D. Because of its proper prices.

Nowadays many people are concerned about the problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment.
Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers so they throw them in the trash.
National Solid Waste Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected.
The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills (垃圾填埋场) and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore says, “There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components there are some materials that should not really be in the landfill.”
Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in order to keep e-waste poisons like lead (铅) and mercury (汞) out of garbage dumps.
This year several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted bans on e-waste in landfills. Chaz Miller says more can be done to boost electronic waste recycling.
“We can do much better,” noted Miller. “I think clearly our goal should be to do as well as we do recycling newspapers.”
1.Which of the following does NOT belong to e-waste?
A. Old televisions. B. Old computers.
C. Old cell phones. D. Old newspapers.
2.Why is e-waste banned from landfills in many states?
A. Because it can not be recycled.
B. Because the landfills are already full.
C. Because it might damage the environment.
D. Because it can be shipped to other countries.
3.According to Mike Fannon, what might be the best way of dealing with e-waste?
A. Recycling it. B. Selling it.
C. Burying it. D. Breaking it.
4.What can we learn from the passage?
A. Chaz Miller works for EPA.
B. Miller is optimistic about the future of e-waste.
C. At present, less than 10 percent of e-waste is recycled.
D. All states in the US have banned e-waste from landfills.
