2. Passage Thirty-SixTraditionally， universities have carried out two main activities: research and teaching.Many experts would argue that both these activities play a critical role in serving the community.The fundamental question， however， is how does the community want or need to be served? In recent years universities have been coming under increasing pressure from both the governments and the public to ensure that they do not remain “ivory towers (象牙塔)” of study separated from the realities of everyday life.University teachers have been encouraged， and in some cases constrained (强迫)， to provide more courses which produce graduates with the technical skills required for the commercial use.If Aristotle wanted to work in a university in the UK today， he would have a good chance of teaching computer science but would not be so readily employable as a philosopher.A post-industrial society requires large numbers of computer programmers， engineers， managers and technicians to maintain and develop its economic growth but “man”， as the Bible says， “does not live by bread alone.” Apart from requiring medical and social services， which do not directly contribute to economic growth， the society should also value and enjoy literature， music and the arts.Because they can also promote economic growth.A successful musical play， for instance， can contribute as much to the Gross National Product through tourist dollars as any other things.We can infer from the second paragraph that ().

2. Passage Twenty-SixToday just as technology changed the face of industry， farmers have undergone an “agricultural revolution”.On the farm of today， machines provide all the power.One of the most important benefits will be the farm computer.A few forward-looking farmers are already using computers to help them run their farms more efficiently.The computers help them keep more accurate records， so they can make better decisions on what crops to plant， how much livestock to buy， when to sell their products， and how much profit they can expect.Many computer companies have been developing special computer programs just for farmers.Programs are being written for hog (猪)producers， grain farmers， potato farmers， and dairy farmers.In the future， farmers will be able to purchase computer programs made to their needs.Because of the growing importance of computers on the farm， students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses.There can be no doubt that farmers will rely on computers even more in the future.While the old-time farm depended on horse power， and modern farms depend on machine power， farms of the future will depend on computer power.Another technological advance which is still in the experimental stage is the robot， a real “mechanized hired hand” that will be able to move and， in some ways， think like a human being.Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century.Unlike farmers of the present， farmers of the future will find that many day-to-day tasks will be done for them.Scientists are now developing robots that will be able to shear (修剪)sheep， drive tractors， and harvest fruit.Even complex jobs will be done by robots.For example， in order to milk their cows， farmers must first drive them into the special barn (畜棚)， then connect them to the milking machines， watch the machines， and disconnect them when they are finished.In the future， this will all be done by robots.In addition， when the milking is completed， the robots will automatically check to make sure that the milk is pure.The complete mobilization of the farm is far in the future， but engineers expect that some robots will be used before long.According to the passage， computers can not help farmers decide ().

5. Passage FifteenBig data can be defined as information that is too big or complex to be contained or processed by any one machine or person.As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy.When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology.Now， he is part of the big data industry that includes Google and Facebook.Dailly’s research company， Monar Consulting， started three years ago with five employees.The company’s earnings have increased by 25% each year.It now employs 90 people.“What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said.He noted the importance of working with people with different skills.“We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and sales people，” Dailly said.Companies like Dailly’s employ recent college graduates.The industry profits from the ideas of these young men and women.New forms of data also make it possible for some observers to predict the future.They are more valuable to companies than the traditional forms of data recording or reporting.“We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done.That helps people take proper action in advance.This makes it much more useful for strategy.”Julian Dailly dismisses concerns that computers have finally taken control of our daily lives.“Some may worry that humans will be allowed to be replaced by machines.I think it’s a fantasy.”According to Dailly， the idea that humans may be replaced by machines ().

1. Passage Thirty-ThreeWe all know that DNA has the ability to identify individuals but， because it is inherited， there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended)， tribal group and even an entire population.Molecular Genealogy (宗谱学)can use this unique identification provided by the genetic markers to link people together into family trees.Pedigrees (家谱)based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption， illegitimacy or lack of records.There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.The main objective of the Molecular Genealogy Research Group is to build a database containing over 100，000 DNA samples from individuals all over the world.These individuals will have provided a pedigree chart of at least four generations and a small blood sample.Once the database has enough samples to represent the world genetic make-up， it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records.Theoretically， any individual will someday be able to trace his or her family origins through this database.In the meantime， as the database is being created， molecular genealogy can already verify possible or suspected relationships between individuals.“For example， if two men sharing the same last name believe that they are related， but no written record proves this relationship， we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体)，” explains Ugo Perego， a member of the BYU Molecular Genealogy research team.People in a large area may possess the same DNA thread because ().

1. Passage Twenty-EightOn November 19， 1863， Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery.The Civil War was still going on.There was much criticism of President Lincoln at the time.He was not at all popular.He had been invited to speak at Gettysburg only out of politeness.The principal speaker was to be Edward Everett， a famous statesman and speaker of the day.Everett was a handsome man and very popular everywhere.It is said that Lincoln prepared his speech on the train while going to Gettysburg.Late that night， alone in his hotel room and tired out， he again worked briefly on the speech.The next day Everett spoke first.He spoke for an hour and 57 minutes.His speech was a perfect example of the rich oratory of the day.Then Lincoln rose.The crowd of 15，000 people at first paid little attention to him.He spoke for only nine minutes.At the end there was little applause.Lincoln turned to a friend and remarked， “I have failed again.” On the train back to Washington， he said sadly， “That speech was a flat failure， and the people are disappointed”.Some newspapers at first criticized the speech， but little by little as people read the speech， they began to understand better.They began to appreciate its simplicity and its deep meaning.It was a speech which only Abraham Lincoln could have made.Today， every American school child learns Lincoln’s Gettysburg Address by heart.Now everyone thinks of it as one of the greatest speeches ever given in American history.In 1863， Abraham Lincoln was ().
