[简答题]
In reading the pages of American Scientist, I have been struck by the stunning progress being made in science and engineering, new phenomena discovered, new materials synthesized, new methods developed. (46) What I see behind many of these exciting stories is the widespread and even revolutionary use of distributed intelligence that is made possible by the "wiring" of the scientific community. It is more than a time saver or a communication enhance; it is enabling us to think in new ways and its impact on society may be monumental.

(47) This is an age of "knowledge and distributed intelligence", in which knowledge is available to anyone, located anywhere, at any time; and in which power, information, and control are moving from centralized systems to individuals.

[单项选择]In America’s fiercely adversarial legal system, a good lawyer is essential. Ask O.J. Simpson. In a landmark case 35 years ago, Gideon v. Wainwright, a unanimous Supreme Court ruled that indigent defendants must be provided with a lawyer at state expense because there could be no fair trial in a serious criminal case without one. "This seems to us to be an obvious truth," wrote Justice Hugo Black in his opinion. At the time, the decision was hailed as a triumph for justice, an example of America’s commitment to the ideal of equality before the law.
This is the image most Americans still have of their criminal-justice system -- the fairest in the world, in which any defendant, no matter how, gets a smart lawyer who, too often, manages to get the culprit off on a technicality. Nothing could be further from the truth. About 80% of people accused of a felony have to depend on a publicly-provided lawyer; but over the past two decades the eagerness of politicians to look harsh on crime,

[简答题]
In your university work, you will be expected to give oral presentations in the form of re- ports or simply in the form of answers to questions. There are several things you can do to make your oral presentations clear and easy to understand. The Cumdamental point to realize is that speech and writing are different. If you want to be best understood, you can’t simply read your written report aloud. The biggest difference between spoken and written language is that readers can look back over the printed words when they don’t understand. In spoken language, however, listeners can’t go back and check the words. They can rely only on memory. So the first principle to keep in mind when you’re planning to speak in public is that you have to help the listener’s memory. This means that an oral report can’t deliver information as rapidly as a written report. That is, you can’t have as many pieces of new information packed into the same number of w
