单选题Artificial Speech Because speech is the most convenient form of communication, in the future we want essentially natural conversations with computers. The primary point of contact will be a simple device that will act as our window into the world. It will have to be small enough to slip into our pocket, so there will be a screen but no keyboard: you will simply talk to it. The device will be permanently connected to the Internet and will keep relevant information up to you as it comes in. Such devices will evolve naturally in the next five to ten years. Just how quickly people will adapt to a voice-based Internet world is uncertain. Many believe that, initially at least, we will need similar conventions for the voice to those we use at present on screen: click, back, forward, and so on. But soon you will undoubtedly be able to interact by voice with all those IT-based services you currently connect with over the Internet by means of a keyboard. This will help the Internet serve the entire population. Changes like this will encompass (围绕，包围) the whole world. Because English is the language of science, it will probably remain the language in which the technology is most advanced, but most speech-recognition techniques are transferable to other languages provided (假如，若是)there is sufficient motivation to undertake the work. Of course, in any language there are still huge problems for us to solve. Carefully dictated, clear speech can now be understood by computers with only a 4～5 percent error rate, but even the most advanced technology still records 30～40 percent errors with spontaneous speech. Within ten years we will have computers that respond to goal-directed conversation, but for a computer to have a conversation that takes into account human social behaviors is probably 50 years off. We are not going to be chatting to the big screen in the living room just yet. In the past, insufficient speed and memory have held us back, but these days they are less of an issue. However, there are those in the IT community who believe that current techniques will eventually hit a brick wall. Personally, I believe that incremental (不断增长的) developments in performance are more likely. But it is true that by about 2040 or so, computer architectures will need to become highly parallel (并行的) if performance is to keep increasing. Perhaps that will inspire some radically new approaches to speech understanding that will replace the methods we are developing now.

单选题Libraries A library is a place to find out about almost anything. In it there are mostly books. There are also pictures, papers, magazines, maps, tapes, and records. Special science and art shows, story hours, movies, plays, and contests may also be held there. Long long ago, a library had only books, and these were hard to get. Books could be written only by hand. There were so few that no one was allowed to take them out of the library. After the printing press was invented, books could be made faster. This helped libraries get more books. To borrow a book to take home today, a person just needs a library card. In many libraries a helper checks the book out. He or she stamps the card. The mark shows the date by which the book must be returned. If the book is returned late, the person must usually pay money, called a fine. In some libraries a computer has taken the place of stamping. Books in a library are put into a certain order to help people find what they want. All books about animals may be placed together. Or all stories written by the same person may be placed together. A big set of cards lists all the library"s books in alphabetical order. It is called the card catalog. It tells where each of them can be found. People who live far in the country may find it hard to get to a library. For these people there are bookmobiles, which are large trucks filled with books. Each truck travels to many places. All the people have to do meet the truck and choose the books they would like to read.

单选题Cell Phones: Hang Up or Keep Talking? Millions of people are using cell phones today. In many places it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication--having a mobile phone shows that they are cool and connected. The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health. On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the tissues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about. As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

单选题Facebook Wants to "Listen" to Your Music and TV Facebook is to release a new feature on its mobile app that "listens" to your music and TV shows. If the song or show is recognized by the app, users can publish the information on their profile or to selected friends. The service hopes to take advantage of the "second screen" trend, which sees fans of TV shows, in particular sharing their experiences on social networks. However, some users have privacy concerns. The feature, which will be available in a few weeks" time, uses the microphones inside users" smartphones to detect nearby music or TV shows. As the user begins writing a status update, a small animated icon will appear at the top of the app. If the app detects the appropriate audio signals and finds a match from its database, the user can then share what he or she is watching or listening to. Facebook says the feature can be turned off at any time, the audio recording is not stored anywhere and the device cannot identify background noise or conversations. "If you share music, your friends can see a 30-second preview of the song. For TV shows, the story in News Feed will highlight the specific season and episode you"re watching," Facebook said in a statement. The company hopes this new method of sharing user listening and watching habits will take advantage of the five billion status updates related to TV and music experiences that the social networking giant sees on a yearly basis. However, automating part of the sharing process has left some users suspicious, with Nicole Simon commenting on TechCrunch that: "While the idea is nice and technology really interesting, I have no interest in Facebook "observing" my audio and surrounding. Yes, it starts currently as opt-in, and only on occasion, but there is no trust from my side for even that." The BBC understands that this new feature was not specifically designed to enhance Facebook"s advertising. However, the company could push an advertisement to a user"s phone based on their tracked listening habits. This is in keeping with Facebook"s current approach to advertising, which uses publicly provided information on users" profiles to push advertisements that are more relevant to each individual user. The basic idea behind Facebook"s feature is not a new one—since 2002 Shazam, which has recently seen a $3 million investment from Sony Music Entertainment, has been providing a similar audio recognition service, with its website describing itself as "a mobile app that recognizes music and TV around you". Facebook"s much larger user base could pose a future threat to the comparatively smaller company.

单选题下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}}Prolonging Human Life{{/B}} Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have roles which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, they must often "go on welfare” if they have a serious illness. When older people become senile or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with must members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet {{B}}this need{{/B}}, a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply "dumping grounds" for the dying in which "care" is given by poorly paid, overworked, and underskilled personnel.
