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项中选出最佳的一项，并把它前面的大写字母填入左边的括号里。{{B}}A{{/B}} Very soon a computer will be able to teach you English. It will also be able to translate any language for you too. It's just one more incredible result of the development of microprocessors--those tiny parts of a computer commonly known as "silicon chips". So give up going to classes, stop buying more textbooks and relax. In a couple of years you won't need the international language of English. Already Texas instruments in the United States is developing an electronic translation machine. Imagine a Spanish secretary, for example, who wants to type a letter from the boss to a business man in Sweden. All he or she will have to do is this; first type the letter in Spanish. The letter will appear on a television screen. After a few seconds the translated letter will appear on another television screen in Stockholm in perfect Swedish. And that's not all. Soon a computer will be able to teach you English, if you really want to learn the language. You'll sit in front of a television screen and practise endless structures. The computer will tell you when you are correct and when you are wrong. It will even talk to you because the silicon chips can change electrical impulses into sounds. And clever programmers can predict the responses you, the learner, are likely to make. So think of it. You will be able to teach yourself at your own pace. You will waste very little time, and you can work at home. And if after all that, you still can't speak English you can always use the translating machine. In a few years, therefore, perhaps there will be no need for BBC Modern English, or BBC English by Radio programs--no more textbooks or teachers of English. Instead of buying an exciting new textbook, the computer will ask you to replace it with microprocessor one thousand nine hundred and eighty-four. Fast, reliable and efficient language learning and translating facilities will be available to you. Think of that no more tears or embarrassing moments. One little problem is that a computer can't laugh yet-- but the scientists are working on it. Happy learning!

单选题The law of private international tribunals with respect to conflicts of interest of arbitrators is quite extensive, albeit by no means uniform. It relates both to what will disqualify an arbitrator and to what the arbitrator must disclose during the selection process. Most national legal systems have statutory roles as to the types of interests, relationships, and experiences that disqualify an arbitrator. Not infrequently, the disqualifying factors are identical for arbitrators and judges, although they may treat domestic and international arbitration somewhat differently, and may indeed supplement the international roles with additional features. A closer look reveals that courts and arbitration agencies tend to apply the regulations relatively lightly, recognizing that arbitrators move in the highly interconnected world of affairs, and do not stand aloof from commerce as judges do. Accordingly, acquaintanceship with the parties and their counsel does not suffice to disqualify, whereas actual business or legal connections will. Inasmuch as judges do not seek more work, although arbitrators generally do, suspicions arise that an arbitrator's favor may incline to the party or counsel who has in the past and may again in the future provide employment. The uncertainty in the field is at its most troubling when arbitrators are party-appointed. Some argue that such arbitrators should fulfill the same functions and satisfy the same qualifications as third-party arbitrators, others dispute any real claim to objectivity. The latter view has had considerable currency, particularly in the United States, where courts and drafters of state laws regard such advocates as pawns of the appointers. Imposing standards of neutrality, and disinterestedness on them would be futile. It follows from this dichotomy between party-appointed and non-party-appointed arbitrators that opinion on the question of their nationality is also split. A party needs to be expected to choose a fellow national. This question of nationality is acute when one party to the arbitration is a governmental agency and one or more of the arbitrators are likewise nationals; a foreign enterprise contract calling for such arbitration may be foolhardy. The slate is largely blank with respect to roles for the conduct of arbitrators outside the field of conflict of interests. Considering only the matter of exparte communications, American case law is astonishing lax, refusing to set aside awards where such communication obtained between an arbitrator and a party without the presence of the other party, thereby violating evidentiary rules requiring the attendance of both parties. The differences in views on this topic indicate how useful a set of guidelines might be.

单选题There are a thousand reasons why more research is needed on solar energy.

单选题If you are caught in a downpour, it is better to run for shelter than walk, researchers in the US advise. This may sound obvious, but an earlier study in Britain suggested that you would get just as wet running as walking. In 1995, Stephen Belcher of the University of Reading and his students calculated how much water falls on top of your head and how much you sweep up on your front as you move forward. Obviously, you would get wettest standing still, and less wet the faster you moved. But the Reading team found that the benefits of running faster than about 3 metres per second—which they described as a walking pace—were tiny. Thomas Peterson and Trevor Wallis, meteorologists at the National Climatic Data Center in Asheville, North Carolina, had a hunch that this was wrong. They realized that the Reading team had overestimated the average walking pace, so they reworked the calculations for a walking pace of 1.5 metres per second and a running speed of 4 meters per second. Peterson and Wallis conclude in the latest issue of Weather that a walker would get 16 per cent wetter than a runner over a distance of 100 meters in drizzle. In heavy rain, this would rise to 23 per cent. When the researchers allowed for the way that runners tend to lean forward, sheltering the front of their bodies but increasing the rainfall on their backs, they found that a walker would get 36 per cent wetter than a runner in heavy rain. Not content with theory alone, Peterson and Wallis decided to test their ideas. " If verification requires an $ 80 million satellite, one may have to forgo verification, " says Peterson. "But if it involves a simple experiment, that" s another matter. " Peterson and Wallis are roughly the same size. Wearing identical clothing, one ran 100 meters in heavy rain and the other walked. They weighed their clothes before and after the experiment. This showed that the walker bad absorbed 0.22 kilograms of water, while the runner had soaked up only 0. 13 kilograms. This is about 40 per cent less, is line with the model" s predictions. Belcher says that his team" s work was a bit of fun, and that apart from the confusion over what a typical walking speed is, their results were similar to those of Peterson and Wallis. "I"m delighted to see that their experiments gave results in qualitative agreement with the model," says Belcher. But why not just take an umbrella? For anyone thinking of taking the easy way out, Wallis has a warning: "Running with an umbrella has a negative impact on your aerodynamics. "
