Article: The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the prefix = st1 /U.S.army. Originally limited to researchers at a handful of universities and government departments, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 millionU.S.citizens had access to the Internet at home or work. More and more Americans arc paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet. Internet banking is also becoming increasingly popular. With lower overhead costs in terms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charge lower rates on loans than traditional banks. "Brick and mortar" banks are increasingly offering online banking services via some special websites to enlarge their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double during the next two or three years. Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need many security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that out-siders cannot disturb the organization's internal networks or gain unauthorized access to the organization's computer systems and data. Question: What is this text mainly about? Yes or no, is the answer "The effect, ct of increasing commercial use of the Internet."?
Yes

Article: Cowboy or spaceman? A dilemma for a children's party, perhaps. But also a question for economists, argued Kenneth Boulding, a British economist, in an essay published in 1966. We have run our economies, he warned, like cowboys on the open grassland: taking and using the world's resources, confident that more lies over the horizon. But the Earth is less a grassland than a spaceship--a closed system, alone in space, carrying limited supplies. We need, said Boulding, an economics that takes seriously the idea of environmental limits. In the half century since his essay, a new movement has responded to his challenge. "Ecological economists", as they call themselves, want to revolutionise its aims and assumptions. What do they say--and will their ideas achieve lift-off? To its advocators, ecological economics is neither ecology nor economics, but a mix of both. Their starting point is to recognise that the human economy is part of the natural world. Our environment, they note, is both a source of resources and a sink for wastes. But it is ignored in conventional textbooks, where neat diagrams trace the flows between firms, households and the government as though nature did not exist. That is a mistake, say ecological economists. There are two ways our economies can grow, ecological economists point out: through technological change, or through more intensive use of resources. Only the former, they say, is worth having. They are suspicious of GDP, a crude measure which does not take account of resource exhaustion, unpaid work, and countless other factors. In its place they advocate moreholistic approaches, such as the Genuine Progress Indicator (GPI), a composite index that includes things like the cost of pollution, deforestation and car accidents. While GDP has kept growing, global GPI per person peaked in 1978: by destroying our environment we are making ourselves poorer, not richer. The solution, says Herman Daly, a former World Bank economist and eco-guru, is a "steady-state" economy, where the use of... Question: The comparison between GDP and GPI data in 1978 has warned us that . Yes or no, is the answer "we are gaining material wealth by destroying nature"?

Ques: Article: On Nov.18,1995,Itzhak Perlman,the violinist,came on stage to give a concert.If you have ever been to a Perlman concert,you know that getting on stage is no small achievement for him.He was stricken with polio as a child,and so he walks with the aid of two crutches. The audience sat quietly while he makes his way across the stage to his chair and begins his play.But this time,something went wrong.Just as he finished the first few bars,one of the strings on his violin broke.We thought that he would have to stop the concert.But he didn't.Instead,he waited a moment,closed his eyes and then signaled the conductor to begin again. Of course,anyone knows that it is impossible to play a pleasant work with just three strings.I know that,and you know that,but that night Itzhak Perlman refused to know that. When he finished,there was a breathtaking silence in the room.And then people rose and cheered.There was an extraordinary outburst of applause from every corner of the auditorium. He smiled,wiped the sweat from this brow and then he said-not proudly,but in a quiet,holy attitude-"You know,sometimes it is the artist's task to find out how much music you can still make with what you have left." This powerful line has stayed in my mind ever since I heard it.And who knows?Perhaps that is the meaning of life-not just for artists but for all of us. So,perhaps our task in this fastchanging,puzzling world in which we live is to make music,at first with all that we have,and then,when that is no longer possible,to make music with what we have left. Question: What made Itzhak Perlman's performance at the concert special on Nov.18,1995? Yes or no, is the answer "One string of the violin got broken."?
Ans: No

Article: The clock struck eleven at night. The whole house was quiet. Everyone was in bed except me. Under the strong light, I looked sadly before me at a huge pile of that troublesome stuff they call "books". I was going to have my examination the next day. "When can I go to bed?" I asked myself. I didn't answer. In fact I dared not. The clock struck twelve. "Oh, dear!" I cried. "Ten more books to read before I can go to bed!" We pupils are the most _ creatures in the world. Dad does not agree with me on this. He did not have to work so hard when he was a boy. The clock struck one. I was quite desperate now. I forgot all I had learned. I was too tired to go on. I did the only thing I could. I prayed, "Oh God, please help me pass the exam tomorrow. I do promise to work hard afterwards, Amen." My eyes were so heavy that I could hardly open them. A few minutes later, with my head on the desk, I fell asleep. Question: Reviewing his lessons that night didn't help him because _ . Yes or no, is the answer "he hadn't studied hard before the examination"?
No
