Ford
1 Ford’s great strength was the manufacturing .ring process-not invention．Long before he started a car company，he was a worker, known for picking up pieces of metal and wire and turning them into machines．He started putting cars together in 1 89 1. A1though it was by no means the first popular automobile，the Model T showed the world use how creative Ford was at combining technology and market．

2 The company‘s assembly line alone threw America’s Industrial Revolution into overdrive(高速运转)．Instead of having workers put together the entire Car，Ford’s friends，who were great toolmakers from Scotland，organized teams that added parts to each Model T as it moved down aline．By the time F0rd’s Highland Park plant was humming(嗡嗡作响)along in 1914，theworld’s first automatic conveyor belt could turn out a car every 93 minutes．

3 The same year Henry Ford shocked the world with the$5.a．day minimum Wage scheme．the greatest contribution he had ever made．The average wage in the auto industry then was$2.34 for a 9.hour shift．Ford not only doubled that．he also took an hour off the workday．In those years it was unthinkable that a man could be Paid that much for doing something that didn’t involve an awful lot of training or education．The wall Street Journal called the plan“all economic crime”．and critics everywhere 1aughed at Ford．

4 But as the wage increased later to daily$i0，it proved a critical component of Ford’s dream to make the automobile accessible(可及的)to a11.The critics were too stupid to understand that because F0rd had 10wered his costs per car ,the higher wages didn’t matter--except for making it possible for more people to buy Cars． ，

第一篇

U．S．Blacks Hard·hit by Cancer

Death rates for cancer are falling for all Americans．but black Americans are still more likely to die of cancer than whites，the American Cancer Society said Monday

In a special report on cancer and blacks，the organization said blacks are usually diagnosed with cancer later than whites，and they are more likely to die of the disease．

This could be because of unequal(不平等的)access to medical Care。Because blacks are more likely to have other diseases as well，and perhaps because of differences in the biology(生物学)of the can cancer itself, the report added．

“In general，black Americans have less hope of surviving five years after diagnosis thail whites for all cancer sites and all stages of diagnosis．”the report said．

“In describing cancer statistics for black Americans，this report recognizes that many of the differences associated with race may be caused by unfair social and economic differences and unequal access to medical care．”

The cancer society said blacks should be encouraged to get check-ups(体格检查)earlier,When cancer is more treatable．and it said more research is needed to see if biological differences play a role．

‘‘The new statistics emphasize the continuing importance of wiping out these unfair social differences through public policy and education efforts，”the organization said in a statement．

But it also noted a出op in cancer death rates．

“Cancer death rates in both sexes for all sites combined have dropped greatly among black Americans since 1992，as have incidence rates(发生率),”said the report．”

31 Black Americans arc more likely to die of cancer than

第三篇
Technology Transfer in Germany
when it comes to translating basic research into industrial success，few nations can match Germany．Since the 1940s，the nation’s vast industrial base has been fed with a constant stream of new ideas and expertise from science．And though German prosperity(繁荣)has faltered(衰退)over the past decade because of the huge cost of unifying east and west as well as the global economic decline，it still has an enviable(令人羡慕的)record for turning ideas into profit．
Much of the reason for that success is the Fraunhofer Society, a network of research institutes that exists solely to solve industrial problems and create sought。after technologies·But today the Fraunhofer institutes have competition．Universities are taking an ever larger role in technology transfer，and technology parks are springing up all over．These efforts are being complemented by the federal programmes for pumping money into start-up companies．
Such a strategy may sound like a recipe for economic success，but 1t is not without its crities,These people worry that favouring applied research will mean neglecting basic science，eventually starving industry of flesh ideas．If every scientist starts thinking like an entrepreneur(企业家)，the argument goes，then the traditional principles of university research being curiosity．driven：free and widely available will suffer．Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years·
While this debate continues，new ideas flow at a steady rate from Germany’s research networks，which bear famous names such as Helmholtz，Max Planck and Leibniz．Yet it is the fourth network，the Fraunhofer Society，that plays the greatest role in technology transfer．
Founded in 1949.the Fraunhofer Society is now Europe’s largest organisation for applied technology，and has 59 institutes employing 1 2，000 people．It continues to grow．Last year’it swallowed up the Heinrich Hertz Institute for Communication Technology in Berlin．Today,there are even Fraunhofers in the US and Asia．
41 What factor can be attributed to German prosperity?
A Technology transfer．
B Good management．
C Hard work．
D Fierce competition．
42 Which of the following is NOT true of traditional university research?
A It is free．
B It is profit-driven．
C It is widely available． ．
D It is curiosity—driven．
43 The Fraunhofer Society is the largest organisation for applied technology in
A Asia．
B USA．
C Europe．
D Africa．
44 When was the Fraunhofer Society founded?
A In 1940.
B Last year．
C After the unification．
D In 1949.
45 The word “expertise’ ’in line 3 could be best replaced by
A “experts”．
B “scientists”．
C “scholars”．
D “special knowledge”．

Conservation or wasted Effort?
The black robin(旅鸫)is one of the world’s rarest birds．It is a small，wild bird，and it lives only on the island of Little Mangere，off the coast of New Zealand．In 1967 there were about fifty black robins there；in 1977 there were fewer than ten．
Energetic steps are being taken to preserve the black robin．——(47)The idea is to buy another island nearby as a special home，a“reserve”，for threatened wild life，including black robins．The organizers say that Little Mangere should then be restocked(重新准备)with the robin’s food．Thousands of the required plants are at present being cultivated in New Zealand．
Is all this concern a waste of human effort?
what is reasonable and what is unreasonable?
(48)Are we losing our sense of
In the earth’s long，long past hundreds of kinds of creatures have evolved，risen to a degree of success and died out．In the long，long future there will be many new and different forms of life．Those creatures that adapt themselves successfully to what the earth offers will survive for along time．——(49)This is nature’s proven method of operation．
The rule of selection--“the survival of the fittest”—-is the one by which human beings have themselves arrived on the scene．We，being ode of the most adaptable creatures the earth has yet produced，may last longer than most．——(SO)You may take it as another rule that when，at last．human beings show signs of dying out，no other creature will extend a paw(爪)to postpone our departure．On the contrary, we will be hurried out．
Life seems to have grown too tough for black robins．I leave you to judge whether we should try to do anything about it．
A Some creatures，certain small animals，insects and birds，will almost certainly outlast (比……长久)man，for they seem even more adaptable．
B Those that fail to meet the challenges will disappear early．
C Detailed studies are going on，and a public appeal for money has been made．
D Both represent orders in the classification of life
E Is it any business of ours whether the black robin survives or dies out?
F These are the only black robins left in the world

Unpopular Subjects?
Is there a place in today’s society for the study of useless subjects in our universities? Just over 100 years ago Fitzgerald argued in a well-written letter (51)Nature that

“Universities must be allowed to study useless subjects- (52)they don’t，who will?，”He went 0n to use the (53)of Maxwell’s electrodynamics_(电动力学)as onecase where a“useless subject” has been transformed to a useful subject．

Nowadays this argument is again very much (54)in many universities．Indeed one suspects that it is one of those arguments that must be (55)anew(重新)by

each generation．But now there is an added twist ~)--subjects must not only be useful，they must also be (56)enough that students will flock(蜂拥)to d0 them，and even flock to pay to do them．

As universities become commercial operations，the pressure to——(57)subjects or departments that are less popular will become stronger and stronger, Perhaps this is most

strongly——(58)at the moment by physics．There has been much——(59)in the press of universities that are closing down physics departments and incorporate them with

mathematics or engineering departments．

Many scientists think otherwise．They see physics as a——(60)science，which must be kept alive if only to (61)a base for other sciences and engineering．It is of

their great personal concern that physics teaching and research is under (62)in many universities．How Can it be preserved in the rush towards commercial competition? A major turnaround(转变)in student popularity may have to——(63)until the industrial world discovers that it needs physicists and starts paying them well．

Physics is now not only unpopular；it is also“hard”．We can do more about the latter by (64)teaching in our schools and universities．We can also (65)

cooperative arrangements to ensure that physicists keep their research and teaching up to date

47．正确答案为C。第二段第一句说，人们正采取一些积极的办法来保护这种鸟类。采取什么办法呢?选项C说，一方面详细的研究工作正在进行，另一方面人们已经募集了许多钱来从事保护工作。选项c正是对本段第一句的说明或解释，故选项C为正确答案。
48．正确答案为E。选项E是一个问句，第三段中的第一句和最后一句也是问旬。根据这个线索我们也可以做出正确选择。选项E的意思是说，黑旅鸫消失或是保存下来关我们什么事吗?把它放到原文中去，意思连起来顺畅，故选E。
49．正确答案为B。文章第四段主要在谈地球上的万物都遵循优胜劣汰，适者生存的的规律。选项B就是这个意思。注意这里的“those”指代的是those creatures。
50．正确答案为A。这一段还在谈适者生存的规律，其中提到地球上的人类可能比某些物种存活的长久，选项A则说的是，有些物种(一些小动物、昆虫或鸟类)却比人存活的更久。此旬意思可以和前面的意思连得上，所以选A。

第6部分：完形填空

52．答案为A。虽然这几个连词放到空白处词句形式上都成立，但只有选项A放进去后意思才讲得通，故选A。
