参考解析
解析：本题给出的信息是正确的。第一段提到：so there will be a screen but no keyboard: you will simply talk to it．从这句话中可知，将来的电脑将只有一个屏幕，而没有键盘，我们只需要向它说话即可。因此，虽然我们现在使用键入或点击的方式，但将来只用说就可以了。
文章没有谈到这方面的信息。文章中只提到“它得小到可以装入你的衣兜”，但并没有和火柴盒作比较。
文章没有谈到这方面的信息。文章只在第三段中提到了“英语是科学界使用的语言”，但没有谈及法语。
本题给的信息是错误的。文章中第四段提到：but for a computer to have a conversation that takes into account human social behaviors is probably 50 years off．但是想要计算机在与我们对话时考虑到人的社会行为，大概得要50年以后了。我们10年内能做到的只是制造出能应答特定话题的计算机。
本题给出的信息是正确的。文中第四段提到：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．可见，计算机在理解清晰话语时错误率为 4%～5%，而识别自发话语时错误率是30%～40%。
本题给出的信息是错误的。文中第五段第一句提到：In the past, insufficient speed and memory have held us back．这说明内存不足只是以前的缺陷，现在已不再成为问题。
本题给出的信息是错误的。文中最后一段提到：Personally, I believe that incremental developments in performance are more likely．这说明作者认为机器性能不断改进的可能性很大，并不是没有改进的余地了。

哪位 帮我翻译一下: 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 on the world. You will simply talk to it. The device will be permanently connected to the Internet and will beep relevant information up to you as it comes in.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, not just techno-freaks.Changes like this will encompass 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 language provided there is sufficient motivation to undertake the work..

共用题干Ecosystem1. The word “ecosystem” is short for ecological（生态的）system. An ecosystem is where living creatures expand within a given area. You can say that an ecosystem is the natural environment where biological organisms（生物）such as plants,animals and humans co-exist in this world. So naturally that includes you and me. Yes,we are all members of an ecosystem!2 .There are different kinds of ecosystems depending on the type of surface or environ-ment. Most are naturally made such as the ocean or lake and the desert or rainforest.Some are man-made or artificial to encourage co-habitation（同居）between living and non-living things in a monitored environment,such as a zoo or garden.3 .Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone. Plants raised in the earth need air and collect sunlight to help them grow. When they grow,the plants and its fruits or flowers eventually become a source of food to animals,microorganisms（微生物）and even hu- mans,of course. Food is then converted to energy for the rest of us to function,and this hap-pens in a never-ending cycle until the living creatures die and break up back in the earth.4 .Ecosystems are the basis of survival for all living things.We depend on plants and ani-mals for food. In order for us to exist,we need to grow and care about other organisms. We also need to care for the non-living things within our environment like our air and water so we can continue living as a population. Since plants,animals and humans are all of various species（物种）,we all play a role in maintaining the ecosystem.5 .To preserve our ecosystems,we should stop using too much energy,which happens when we consume more than our share of resources. Humans should not disturb the natural habitat（栖息地）of plants and animals,and allow them to grow healthily for the cycle to con-tinue. Too many people in a habitat can mean displacement（搬迁）: imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ru- in the environment and cause destruction of existing plants and animals.To protect our ecosystems we should not use more than______.A: our share of resourcesB: a biological creatureC: a given areaD: the maintenance of the ecosystemE: the source of foodF: various species
We are using up our natural resources too quickly and at the same time we are__our environment with dangerous chemicals.A.protectingB.savingC.pollutingD.fighting
We appreciate your patience and hope to serve you in a timelier manner in the future. ____ , please contact our order department at 716-555-0160 with any questions .A.insteadB.meanwhileC.in contrastD.besides
共用题干Messages from the Media1.The weather forecast,a story about the candidates in an election,and movie reviews are examples of messages from the media. A communication medium , of which the plural（复数的） form is media,is a means of communicating a message.Examples of media are television,radio, newspapers and books and the telephone.The media that can reach many people at once are callemass media.2.It is not difficult to think of other messages we receive through the mass media. Every day we get hundreds of them.Think about advertisements,for example.We see and hear these messages almost everywhere we go.Advertisements are important messages,even though they are sometimes annoying.They help us compare and evaluate products.3.Most of us get more information from the media than from the classroom. Think for a moment, about how you learn about local news and events.Do you depend on other people or the media?What about international news?What is the most important source of information for you?People who are asked this question usually answer,"Television".4.Think of all the messages you received today.Perhaps you read a newspaper during breakfast, or maybe you read advertisements on billboards（露天广告牌）on your way to school. Did you listen to a weather forecast or the sports news on the radio this morning?Right now you are getting information through a very important medium of mass communication一a book.5.We use the information we get from radio,television,newspapers and other media to make decisions and form opinions.That is why the mass media are so important.Editorials and articles in newspapers help us decide how to vote,consumer reports on television help up decide how to spend our money,and international news on the radio makes us think and form opinions about questions of war and peace.For most people television is the most important________.A:sports newsB:our decisions and opinionsC:mass communicationD:our messagesE:source of information F: the mass media

共用题干第二篇Protection of WildlifeDemands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest Europe.Studies by the Council of Europe,of which 21 countries are members, have shown that 1 percent of reptile species and 24 percent of butterflies are in danger of dying out.European concern for wildlife was outlined by Dr. Peter Baum,an expert in the environment and nature resources division of the Council,when he spoke at a conference arranged by the administrators of a British national park.The park is one of the few areas in Europe to hold the Council's diploma for nature reserves of the highest quality,and Dr. Baum had come to present it to the park once again.He was afraid that public opinion was turning against national parks,and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.No area could be expected to survive both as a true nature reserve and as tourist attraction,hewent on.The short view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future."We forget that they are the guarantee of life systems,on which any built-up area ultimately depends,"Dr. Baum went on,"We could manage without most industrial products,but we could not manage without nature.However,our natural environment areas,which are the original parts of our countryside,have shrunk to become mere islands in a spoiled and highly polluted land mass."Although we all depend on the resources of nature for our survival,________.A:industrial products are replacing all our natural resourcesB:it is only on islands that nature survivesC:we have forgotten what our original countryside looked likeD:we have allowed areas of countryside to be spoilt by industrial development

问答题There are great impediments to the general use of a standard in pronunciationcomparable to that existing in spelling (orthography). One is thefact that pronunciation is learnt ‘naturally’ and unconsciously, and orthography 1．_______is learnt deliberately and consciously. Large numbers of us, in fact, remainthroughout our lives quite unconscious with what our speech sounds 2．_______like when we speak out, and it often comes as a shock when we 3．_______firstly hear a recording of ourselves. It is not a voice we recognize at once, 4．_______whereas our own handwriting is something which we almost always know. We 5．_______begin the ‘natural’ learning of pronunciation long before we start learning toread or write, and in our early years we went on unconsciously imitating and 6．_______practicing the pronunciation of those around us for many more hours per every 7．_______day than we ever have to spend learning even our difficult English spelling.This is ‘natural’, therefore, that our speech-sounds should be those of our im 8．_______mediate circle; after all, as we have seen, speech operates as a means of holding acommunity and to give a sense of ‘belonging’.
