3. Passage Twenty-FiveOnline dating has just been revealed to be one of the most common ways to start a relationship.But new research reveals that the concept is still highly flawed (有缺陷的).An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles， users can be overwhelmed and put off by the volume of choice， defeating the purpose.The research， by Northwestern University and published in the journal Psychological Science in the public interest， found that the processes involved don’t lend themselves to forming strong relationships.The findings also indicated that the concept of an online profile (介绍)is not entirely useful and “can result in treating potential partners as mere objects”.Lead author Eli.J.Finkel explained， “Online dating is a terrific addition for singles to meet.However， there are two problems.” First， studying over seemingly endless lists of profiles of people one does not know， as on Match.com， does not reveal much about them.Second， it “overloads people and they end up shutting down，” he said.He compared it to shopping at “supermarkets of love” and said psychological research shows people presented with too many choices tend to make lazy and often poor decisions.The study’s authors also questioned the algorithms (算法)employed by sites such as eHarmony.com to match people based on their interests or personality—comparing it to having a real estate agent of love.While the algorithm may reduce the number of potential partners from thousands to a few， they may be as unsuitable for each other as two people meeting at random， Dr.Finkel explained， adding the chances are no better than finding a relationship by walking into any bar.“There’s no better way to figure out whether you’re a match with somebody than talking to them over a coffee or beer，” Dr.Finkel said.The phrase “lend themselves to” (Para.3)probably means ().

5. 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.What is the best title for the whole passage?

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 ().

2. Passage ElevenDoctors say anger can be an extremely damaging emotion， unless you learn how to deal with it.They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer.Anger is a normal emotion that we all feel from time to time.Some people express anger openly in a calm and reasonable way.Others burst with anger， screaming and yelling.But still others keep their anger inside.They cannot or will not express it.This is called (repressing)anger.For years some doctors claim that both repressing and expressing anger can be dangerous.They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙).They spend the heart rate， raise blood pressure or sugar level in the blood.As a result， the angry person feels excited and is ready to react.The violent reaction may lead to high blood pressure.However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it.They believe that those who keep their anger inside may face a greater danger of heart disease.Most doctors agree that it is important to learn how to deal with anger.They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about.If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably.They also believe that a good way to deal with anger is to find humor in the situation that has made you angry.After all， it is much healthier to laugh than to get angry.According to some doctors， ().

1. Passage Thirty-OneAdam Smith was the first person to see the importance of the division of labor.He gave us an example of the process by which pins were made in England.“One man draws out the wire， another strengthens it， a third cuts it， a fourth points it， and a fifth gives it a head.Just to make the head requires two or three different operations.The work of making pins is divided into about eighteen different operations， which in some factories are all performed by different people， though in others the same man will sometimes perform two or three of them.”Ten men， Smith said， in this way， turned out twelve pounds of pins a day or about 4，800 pins a worker.But if all of them had worked separately and independently without division of labor， they certainly could not have made twenty pins in a day and not even one.There can be no doubt that division of labor is an efficient way of organizing work.Fewer people can make more pins.Adam Smith saw this， but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still.But division of labor adds nothing new， it only enables people to produce more of what they already have.According to the passage， Adam Smith was the first person to ().

5. 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.Which of the following CANNOT be inferred from the passage?

2. Passage Twenty-OneWhat will man be like in the future—in 5，000 or even 50，000 years from now? We can only make guesses， of course， but we can be sure that he will be different from what he is today.For man is slowly changing all the time.Let us take an obvious example.Man， even five hundred years ago， was shorter than he is today.Now， on average， men are about three inches taller.Five hundred years is relatively short period of time， so we may assume that man will continue to grow taller.Again， in the modern world we use our brains a great deal.Even so， we still make use of only about 20% of the brain’s capacity.As time goes on， however， we shall have to use our brains more and more， and eventually we shall need larger ones.This is likely to bring about a physical change to the head， in particular the forehead will grow larger.Nowadays our eyes are in constant use.In fact， we use them so much that very often they become weaker and we have to wear glasses.But over very long period of time it is likely that man’s eyes will grow stronger.On the other hand， we tend to make less use of our arms and legs.These， as a result， are likely to grow weaker.At the same time， however， our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.In the future， then， both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at.This may well be true.All the same， in spite of all these changes， future man will still have a lot in common with us.He will still be a human being， with thoughts and emotions similar to our own.The evidence that man is changing is that ().

38. Questions 36 to 40 are based on the following passage.Recognizing when a friend or colleague feels sad， angry or surprised is key to getting along with others.But a new study suggests that being sensitive to people’s feelings may sometimes come with an extra dose of stress.This and other research challenge the prevailing view that emotional intelligence is uniformly beneficial to its bearer.In a study， Psychologist Myriam Bechtoldt of the Frankfurt School of Finance and Management in Germany asked 166 male university students a series of question to measure their emotional intelligence.For example， they showed the students photographs of people’s faces and ask them to what extent feelings such as happiness or disgust were being expressed.The students then had to give job talks in front of judges who displayed serious facial expressions.The scientists measured concentrations of stress hormones in the students’ saliva (唾液)before and after the talk.In students who were rated more emotionally intelligent， the stress measures increased more during the experiment and took longer to go back to baseline.The findings suggest that some people may be too emotionally clever for their own good， says Bechtoldt.“Sometimes you can be so good at something that it causes trouble，” she notes.Indeed， the study adds to previous research hinting at a dark side of emotional intelligence.A study published in 2002 in Personality and Individual Differences suggested that emotionally perceptive people might be particularly influenced by feelings of depression and hopelessness.Furthermore， several studies have implied that emotional intelligence can be used to manipulate others for personal gains.
More research is needed to see how exactly the relation between emotional intelligence and stress would play out in women and in people of different ages and education levels.Nevertheless， emotional intelligence is a useful skill to have， as long as you learn to also properly cope with emotions—both others’ and your own， says Bechtoldt.For example， some sensitive individuals may assume responsibility for other people’s sadness or anger， which ultimately stresses them out.Remember， as Bechtoldt says， “you are not responsible for how other people feel.”What does the finding of Myriam Bechtoldt’s study indicate?

A. 　Greater emotional cleverness means less trouble in one＇s life.

B. 　Emotional intelligence helps people succeed in job interviews.

C. 　People＇s psychological wellbeing is related to various factors.

D. 　People may suffer from having a high emotional intelligence.
