单选题The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machine of silicon will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale, we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined; further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

单选题{{B}}Directions: {{/B}}There are three passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and blacken the corresponding letter on the Answer Sheet. {{B}}Passage 1{{/B}}{{B}}Questions 1 to 5 are based on the following passage.{{/B}} It's interesting that the arrival of snow has the effect on people in different countries.(76) {{U}}For some countries it is an important happening to celebrate each year, while for oth-ers a catastrophe (灾害) or even a wonder. {{/U}}But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply creates problems. Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way. Normal communications are affected as well: tele-phone calls become difficult and the post immediately takes more time than usual. And al-most within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops, but mainly be-cause people are frightened and go out and store up with food and so on… just for fear that something bad should happen.But why does snow have this effect? After all, the Swiss, the Austrians and the Cana-dians don't have such problems. It is simply because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs (扫雪机) and machines to spread salt.(77) {{U}}The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on. {{/U}}
