When you send a letter or a postcard, you have to put stamps on the envelope or on the card. When did people first begin to use stamps？ Who was the first to think of this idea？
In the early nineteenth century, people did not use stamps. They had to pay postage (邮费) when they received letters. Sometimes they didn't want to receive a letter at all, but they had to pay money for it. They were unhappy about this. The postage was high at that time, because the post offices had to send many people to get the postage.
Rowland Hill was a school teacher in England. He was the first to think of using stamps in 1850s. He thought it would be much easier for people to use stamps. People could go to the post office to buy stamps and put them on envelopes before they sent the letters. The post office could just put seals (邮戳). on the stamps so that people could not use the stamps again. In this way, the post office did not need to send post men to get postage. It only needed fewer postmen to send letters.
People began to use stamps ______.
A．at the beginning of the nineteenth century
B．in the middle of the nineteenth century
C．more than two hundred years ago
D．when people first sent letters and postcards.

The United Nations Conference on Drug Abuse that took place earlier this year in Vienna, was a very productive meeting. As never before, the nations of the world demonstrated a willingness to confront a common threat.
Most previous international gatherings on this subject have not seen the same intensity of delegate inter est. Many nations have gone through a shock of recognition. A decade ago, only those nations identified as "producing countries" also become "consuming countries", but many have witnessed the growth within their borders of drug trafficking gangs (often allied with terrorists) so powerful they present a danger to the state's stability. Many developing countries now have the worst of both worlds, in that they grow their own people. There is a growing sense of fright in ninny governments that matters are out of control and the single way to recover is through cooperation with other countries.
The high points of the conference were the drafting of two documents, both of which were adopted with out a disagreed vote. One was a joint declaration of intent to combat drag abuse and traffic. The other consisted of many detailed suggestions for particular regional and national policies.
Overall, the conference developed a two-level action plan. The focus was on ways to curb the demand for dangerous drugs and on methods of destroying at least interrupting the distribution process.
On the demand side, the delegates recommended the establishment of a system for collecting information on the nature and scope of narcotics use. In addition, they concluded that drug education should be taught in schools and that governments and labor organizations should act together in the anti-drug campaign in the work place. The delegates also recommended strict adherence to international agreements to curb the supply of narcotics.
The United Nations Conference was held to discuss ______.
A．ideological and individual differences
B．production
C．drug abuse
D．nations of file world

The dot-com collapse may have been a disaster for Wall Street, but here in Silicon Valley, it was a blessing. It was the welcome end to an abnormal condition that very nearly destroyed the area in an overabundance of success. You see, the secret to the Valley's astounding multiple decade boom is failure. Failure is what fuels and renews this place. Failure is the foundation for innovation.
The valley's business ecology depends on failure the same way the tree-covered hills around us depend on fire it wipes out the old growth and creates space for new life. The valley has always been in danger of drowning in the unwelcome waste products of success too many people, too expensive houses, too much traffic, too little office space and too much money chasing too few startups. Failure is the safety valve, the destructive renewing force that frees up people, ideas and capital and recombines them, creating new revolutions.
Consider how the Internet revolution came to be. After half a decade of start-up struggles, for example, hundreds of millions of Hollywood dollars were going up in smoke. It all seemed like a terrible waste, but no one noticed that the collapse left one very important byproduct, a community of laid-off C++ programmers who were now expert in multimedia design, and out on the street looking for the next big thing.
These media geeks were the pioneer of the dot-com revolution. They were the Web's business pioneers, applying their newfound media sensibilities to create one little company after another. Most of these start-ups failed, but even in failure they advanced the new medium of cyberspace. A few geeks, like Silicon Graphics founder Jim Clark, succeeded and utterly changed our lives. In 1994 Clark was unemployed after leaving the company be founded, doggedly trying to develop a new interactive-TV concept. He approached Marc Andreessen, the co developer of Mosaic, the first widely used Internet browser, in hope of persuading Andreessen to help him design his new system. Instead, Andreessen opened Clark's eyes to the Web's potential. Clark promptly tossed his TV plans in the trash, and the two co-founded Netscape, the cornerstone of the consumer-Web revolution.
Like the interactive-TV refugees and generations of innovators before them, the dot-comers are already hatching new companies. Many are revisiting good ideas executed badly in the 1990s, while others are striking out into entirely new spaces. This happy chaos is certain to mature into a new order likely to upset an establishment, as it delivers life-changing wonders to the rest of us. But this is just the start, for revolutions give birth to revolutions. So let's hope for more of Silicon Valley's successful failures.
What is implied in the first sentence？
A．The Silicon Valley blamed its failure on the success of Wall Street.
B．The Silicon Valley is also noted for its complex ecological web.
C．The Silicon Valley takes a vain pride in its overabundant successes.
D．The Silicon Valley would benefit from the collapse in certain ways.

听力原文：Man: Some of us can remember the days when a visit to the supermarket was no fun. If you needed information, there was never an assistant in sight. And when you did find one, they knew less than you. Well, that time is long past, and the seminar I watched recently at our award- winning supermarket was a revelation. It endeavoured to keep sa[es assistants up-to-date with information about food technology, how to access product information on the store intranet, and so on. And that's what gave this supermarket its edge.

A friend of mine named Paul received an automobile from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street urchin was walking around the shiny new car, admiring it. “Is this your car, Mister？” he asked.
Paul nodded. “My brother gave it to me for Christmas.” The boy was astounded. “You mean your brother gave it to you and it didn’t cost you nothing？ Boy, I wish….” He hesitated. Of course Paul knew what he was going to wish for. He was going to wish he had a brother like that. But what the lad said jarred Paul all the way down to his heels.
“I wish,” the boy went on, “that I could be a brother like that.”
Paul looked at the boy in astonishment, then impulsively he added, “Would you like to take a ride in my automobile？”
“Oh yes, I’d love that.”
After a short ride, the boy turned and with his eyes aglow, said, “Mister, would you mind driving in front of my house？”
Paul smiled a little. He thought he knew what the lad wante d. He wanted to show his neighbors that he could ride home in a big automobile. But Paul was wrong again. “Will you stop where those two steps are？” the boy asked.
He ran up the steps. Then in a little while Paul heard him coming back, but he was not coming fast. He was carrying his little crippled brother. He sat him down on the bottom step, then sort of squeezed up against him and pointed to the car.
“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn’t cost him a cent. And some day I’m gonna give you one just like it…, then you can see for yourself all the pretty things in the Christmas windows that I’ve been trying to tell you about.”
