| 第1题：The standardized educational or psychological tests, that are widely used to aid in selecting, assigning, or promoting students, employees, and military personnel have been the target of recent attacks in books, magazines, the daily press, and even inCongress. The target is wrong, for in attacking the tests, critics divert attention from the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools, with characteristics that can be measured with reasonable precision under specified conditions. Whether the results will be valuable, meaningless, or even misleading depends partly upon the tool itself but largely upon the user. All informed predictions of future performance are based upon some knowledge of relevant past performance. How well the predictions will be validated by later performance depends upon the amount, reliability, and appropriateness of the information used and on the skill and wisdom with which it is interpreteD、Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error. Standardized tests should be considered in this context. They provide a quick, objective method of getting some kinds of information about what a person has learned, the skills he has developed, or the kind of person he is. The information so obtained has, qualitatively, the same advantages and shortcomings as other kinds of information. Whether to use tests, other kinds of information, or both in a particular situation depends, therefore, upon the empirical evidence concerning comparative validity, and upon such factors as cost and availability. In general, the tests work most effectively when the traits or qualities to be measured can be most precisely defined (for example, ability to do well in a particular course of training program) and least effectively when what is to be measured or predicted cannot be well defined (for example, personality or creativity). Properly used, they provide a rapid means of getting comparable information about many people. Sometimes they identify students whose high potential has not been previously recognized, but there are many things they do not do. For example, they don’t compensate for gross social inequality, and thus don’t tell how able an underprivileged younger might have been had he grown up under more favorable circumstances. The third paragraph is written mainly to state [A] the functions of educational tests. [B] the dimensions of standardized tests. [C] the bases for using standardized tests. [D] the mixed results of standardized tests. |

| 第3题： 因为照片的影像是通过光线与胶片的接触形成的，所以每张照片都具有一定的真实性。但是，从不同角度拍摄的照片总是反映了物体某个侧面的真实而不是全部的真实，在这个意义上，照片又是不真实的。因此，在目前的技术条件下，以照片作为证据是不恰当的，特别是在法庭上。 |
B、任何证据只需要反映事实的某个侧面。
C．在法庭审理中，有些照片虽然不能成为证据，但有重要的参考价值。
D．有些照片是通过技术手段合成或伪造的。
E．就反映真实性而言，照片的质量有很大的差别。

| 第9题：When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy. Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu. What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago. Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003. We can learn from the last paragraph that ______. A、Microsoft has a strong multiplier effect on the economy B、Boeing is crucial for the survival of other companies C、Seattle area’s employment rate has fallen considerably D、the economic foundation of Seattle isBoeing’s continuing prosperity |
