单选题Online dating, it"s now universally agreed, has its limits. In an effort to combat such digital deception tactics, one of the biggest online dating services, Match.com, has decided to get people out from behind their computers to come out and play. Ironic? No. Regular dating has its weaknesses too, including extreme initial awkwardness when two people first meet and the even extremer awkwardness of the next few hours when a date proves to be a nonstarter. Match. corn believes that with its database of single-but-searching folks, its algorithm (配对规则) for finding compatibility, it can put together a heck of a singles mixer. The company has been quietly inviting members to gatherings for the past few years so far, it has hosted about 60 singles events. After all, it knows where the singles are, and it knows what they say they like. So encouraged has Match been by the results, it has just launched an event service known as Stir, which will host 2,000 to 3,000 singles parties a year, hitting 24 cities in June and 70 in September. Since everyone at the events is looking for a date, the awkwardness is a shared burden and will be easier to shrug off, reasons the company. Also, the dating service is digging deep into its database of 3 million singles, so it can slice and dice the guest list. If it wanted to host a singles event on the south side of Topeka in which everybody was a single parent between the ages of 30 and 40 with an interest in Shar-Pei breeding, it could do that—all while making sure that the ratio of male to female dog lovers is perfectly balanced. Many companies have already tried to turn their online presence into a singles meet-up business. Match.com"s advantage here is the size of its singles pool and the depth of information it has about their preferences. Match"s VP of Strategy and Analytics Amarnath Thombre says the Stir meet-ups are not in response to recent studies that have questioned the effectiveness of compatibility algorithms such as the one Match.com offers but a natural area of development for a company that just wants to get people together. Nevertheless it seems to suggest that online dating might have found its natural limits; it cannot find a mathematical formula for chemistry. To say the dating company has high ambitions for Stir is an understatement. Match considers its foray into the offline world the biggest news in its 17 years of existence. "We will be the largest singles event company in the world," predicts Match. com president Mandy Ginsberg. "We could potentially serve half a million people a year." She also excited about stimulating local economies and revitalizing downtown areas by bringing customers to the local bars where the gatherings take place.

单选题 Few men who find themselves cast as heroes early in life continue to command universal esteem till the end. Sir Edmund Hillary was one. To be the first to reach the top of the world's highest mountain ensured international celebrity and a place in history, but the modesty of a slightly awkward New Zealand beekeeper never departed him. Nor was mountaineering, or indeed beekeeping, his only accomplishment. Two views are often expressed about his life. One is that conquering Everest was everything. No one would play down the role of Tenzing Norgay, the Sherpa who reached the peak with him, possibly even before him; their partnership was like that of Ginger Rogers and Fred Astaire. But it was Sir Edmund who first struggled his way up a crack in the 12-metre (40-foot) rockface that had to be overcome after the south summit if the real one was to be achieved, and below which only oblivion awaited. News of the British-led expedition's triumph on May 29th 1953 reached the world through a report in the London Times four days later. The Times, a sponsor of the expedition, had used an elaborate code to trick any rivals monitoring the radio waves. Its scoop was indeed a coup: June 2nd was the day of Queen Elizabeth's coronation, at which her majesty was crowned. Sir Edmund was a man of action. After Everest came more expeditious in Nepal, a race to the South Pole and further adventures in the Antarctic, the Himalayas and India. But for some onlookers neither these nor even the Everest expedition was especially remarkable: fitness and physical courage are all very well, they argued, but the world's highest peak was simply waiting to be scaled, and a steady traffic nowadays makes its way to the top unnoticed, except for the litter it leaves. Both the indifferent and the awe-struck, however, agree that Sir Edmund's other life was wholly admirable, and he himself said he was prouder of it than of anything else. This was his tireless work for the Sherpas, of whom he had become so fond. Through his efforts, and those of Tenzing, hospitals, clinics, bridges, runways and nearly 30 schools have been built in the Solo Khumbu region of Nepal just south of Everest. If New Zealand claimed Sir Edmund's loyalist, Nepal, and especially its Sherpas, could surely claim his heart.

单选题 阅读下列短文，然后根据短文的内容从每小题的四个选择项中，选出最佳的一项。{{B}}A{{/B}} If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written on it an aceount(记录) of what we did each day, we should be able to give an answer to the question. It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes people did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write. Sometimes, of course, even if the people can not write, they may know something of the past. For most people can tell proudly what their fathers did in the past. This we may call "remembered history". Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written re- cords, such spoken stories are often very helpful.

单选题{{B}}Passage Three{{/B}} The computer has changed the way we work, team, communicate, and play; Virtually ewery kind of organization throughout the world conducts business with computers. Students, teachers, and research scientists use the computer as a learning tool. Millions of individuals and organizations communicate with one another over a network of computers called the Internet. Computer games entertain people of all ages. Almost all computers are electronic digital computers. They are electronic in their use of electric current(电流) to carry information. They are digital in. that they process information as units of electric charge representing numbers. The word digital means having to do with numbers. To enable a computer to process information that is not numerical — such as words, pictures, or sounds — the computer or some other &vice must first digitize: that information. A device digitizes information by translating it into charges that represent numbers. After the computer processes the digitized information by working with the charges, the computer or a device: connected to the computer translates its results hack into their original form. Thus, an artist might use a machine called a scanner to digitize a photograph. The artist would next process the resulting electric charges in a computer to Change the photograph perhaps to add a border. The artist would then use a printer connected to the computer to produce a, copy of the altered photo. Digital computers are one of two general kinds of computers. The other kind is calculating devices called analog computers. An analog computer represents amounts with physical quantities, such as distances along a scale, rather than with numbers.

单选题{{B}}Text 1{{/B}} In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenza-like cases. Influenza is sometimes called “flu” or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus of this influenza. There are three main types of the influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H.O. published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%—20% of the population had become ill. As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs used against all the known sub-groups of virus type A. None of them gave any protection. This then, was something new: a new influenza virus against which the people of the world had no ready help whatsoever. Having isolated the virus they were working with, the two doctors now dropped it into the noses of some specially selected animals, which contact influenza in the same way as human beings do. In a short time the usual signs of the disease appeared. These experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian” flu. The first discovery of the virus, however, was made in China before the disease had appeared in other countries. Various reports showed that the influenza outbreak started in China, probably in February of 1957. By the middle of March it had spread all over China. The virus was found by Chinese doctors early in March. But China was not a member of the World Health Organization and therefore did not report outbreaks of disease to it. Not until two months later, when travelers carried the virus into Hong Kong, from where it spread to Singapore, did the news of the outbreak reach the rest of the world. By this time it was started on its way around the world. Thereafter, WHO’s Weekly Reports described the steady spread of this virus outbreak, which within four months swept through every continent.

单选题{{B}}Passage One{{/B}} The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms but a solid and motionless object that we live. So remote is this "real" table—and most of the other "realities" with which science deals—that it cannot be discussed in terms which have any human value, and though it may receive out purely intellectual credence it cannot be woven into the pattern of life as it is led, in contradistinction to life as we attempt to think about it. Vibrations in the either are so totally unlike, let us say, the color purple that the gulf between them cannot be bridged, and they are, to all intents and purposes, not one but two separate things of which the second and less "real" must be the most significant for us. And just as the sensation which has led us to attribute an objective reality to a non-existent thing which we call "purple" is more important for human life than the conception of vibrations of a certain frequency, so too the belief in God, however ill founded, has been more important in the life of man than the germ theory of decay, however true the latter may be. We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonist trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being is some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as a "truth of correspondence," and it is better perhaps, at least for those of us who have grown up in an age of scientific thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it; that the most important part of our lives-our sensations, emotions, desires, and aspirations-takes place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.
