例1、One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well.
More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon-it's already here.
While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customers for promotional campaigns. Computers are relied on by manufacturers for similar reasons.
Computer-analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future, and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
58. What is this passage mainly about? (1994)
(A) Approaches to the commercial use of computers.
(B) conveniences brought about by computers in business.
(C) Significance of automation in commercial enterprises.
(D) Advantages of credit cards in business.
第三步：A的意思是电脑的商业使用的方法，文章在最后一段讲到了电脑的商业使用的问题，因此A是符合原文意思的;B的意思是商业中电脑带来的便利，原文讲到了B选项，明显的证明是bring better and more efficient services to consumers through the use of computers，所以B也是正确并符合原文意思的;C的意思是自动化在商业企业中的重要性，文章4句话没有讲到自动化的问题，更没有讲到什么重要性，因此C是和原文无关的选项;D的意思是商业中信用卡的重要性，文章在第一段的第一句话就讲到了信用卡，但是没有讲到信用卡的重要性，因此D也是无关选项;因此这个题目的答案必然在A和B中产生。这个时候我们应该比较A和B有什么不同的地方。我们发现A强调的是“方法Approaches”而B强调的是“便利conveniences ”，很显然文章着重讲解的是电脑带来的便利，因此这个题目应该选B;
例2、Exceptional children are different in some significant way from others of the same age. For these children to develop to their full adult potential, their education must be adapted to those differences.
Although we focus on the needs of exceptional children, we find ourselves describing their environment as well. While the leading actor on the stage captures our attention, we are aware of the importance of the supporting players and the scenery of the play itself. Both the family and the society in which exceptional children live are often the key to their growth and development. And it is in the public schools that we find the full expression of society's understanding-the knowledge, hopes, and fears that are passed on to the next generation.
Education in any society is a mirror of that society. In that mirror we can see the strengths, the weaknesses, the hopes, the prejudices, and the central values of the culture itself. The great interest in exceptional children shown in public education over the past three decades indicates the strong feeling in our society that all citizens, whatever their special conditions, deserve the opportunity to fully develop their capabilities.
“All men are created equal.” We've heard it many times, but it still has important meaning for education in a democratic society. Although the phrase was used by this country's founders to denote equality before the law, it has also been interpreted to mean equality of opportunity. That concept implies educational opportunity for all children-the right of each child to receive help in learning to the limits of his or her capacity, whether that capacity be small or great. Recent court decisions have confirmed the right of all children—disabled or not—to an appropriate education, and have ordered that public schools take the necessary steps to provide that education. In response, schools are modifying their programs, adapting instruction to children who are exceptional, to those who cannot profit substantially from regular programs.
61. This passage mainly deals with . (1994)
(A) the differences of children in their learning capabilities
(B) the definition of exceptional children in modern society
(C) the special educational programs for exceptional children
(D) the necessity of adapting education to exceptional children
例3、Scattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots. Unlike most of the world's volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth's surface; on the contrary, many of them lie deep in the interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their trails are milestones that mark the passage of the plates.
That the plates are moving is now beyond dispute. Africa and South America, for example, are moving away from each other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth's interior. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years. The significance of hot spots is not confined to their role as a frame of reference. It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe.
When a continental plate come to rest over a hot spot, the material rising from deeper layer creates a broad dome. As the dome grows, it develops seed fissures (cracks); in at least a few cases the continent may break entirely along some of these fissures, so that the hot spot initiates the formation of a new ocean.
Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability (inconstancy).
20. The passage is mainly about . (1998)
(A) the features of volcanic activities
(B) the importance of the theory about drifting plates
(C) the significance of hot spots in geophysical studies
(D) the process of the formation of volcanoes
hot spots在地球物理学研究中的重要性，文章讲到了hot spots的重要性，那么讲到地球物理学了吗?其实火山运动不就是地球物理学的一部分吗?因此看一个选项讲到没有，不应该仅仅看有没有一样的单词文章中出现没有，而且还要看相近意思的单词或句子出现没有，因此C是符合原文意思的正确选项，但是不能立刻选择，因为我们找的是最佳答案;D的意思是火山构成的过程，虽然这个4句话讲到了火山，但是没有谈及火山构成过程的问题，属于无关选项;因此这个题目应该选C。
