[单项选择]You have probably seen ads in newspaper or on television for mail-order companies. Perhaps a catalogue has been sent to you. Why do people buy things they have not seen in person Some people believe that things can be bought more cheaply by mail. Another good thing about buying by mail is that it is easier and more enjoyable to sit at home and work through a catalogue than to shop around the stores. With a catalogue from a large company, you have your own shop window for almost everything you want to buy.
Buying from a catalogue is so easy. It saves the shopper time and trouble. Sometimes, it saves the shopper money, too. But people often buy more than they can really afford or need, because many things look so good to them They can probably pay a certain part of the full price-a down payment. Then they pay a certain amount of money every month until the goods is paid for in full. But by then they often find what they have bought are of no use at all.

[单项选择] Frustrated with delays in Sacramento, Bay Area officials said Thursday they planned to take matters into their own hands to regulate the region’’s growing pile of electronic trash.
A San Jose councilwoman and a San Francisco supervisor said they would propose local initiatives aimed at controlling electronic waste if the California law-making body fails to act on two bills stalled in the Assembly. They are among a growing number of California cities and counties that have expressed the same intention.
Environmentalists and local governments are increasingly concerned about the toxic hazard posed by old electronic devices and the cost of safely recycling those products. An estimated 6 million televisions and computers are stocked in California homes, and an additional 6,000 to 7,000 computers become outdated every day. The machines contain high levels of lead and other hazardous substances, and are already banned from California landfills (垃圾填埋场).
