1. 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.”Dailly has an education background of ().

1. 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 passage tells us about ().

5. Passage ThirteenTrees are useful to man in three important ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts and floods.Unfortunately， in many parts of the world， man has not realized that the third of these services is the most important.In his eagerness to make money from trees， he has cut them down in large numbers， only to find that without them he has lost the best friends he had.And besides， he is usually too careless to plant and look after new trees.So the forests slowly disappear.This does not only mean that man will have fewer trees.The results are even more serious: for where there are trees， their roots break up soil——allowing the rain to sink in——and also bind the soil， thus preventing it from being washed away easily; but where there are no trees， the rain falls on hard ground and flows away， causing floods and carrying away the rich topsoil.When all the topsoil is gone， nothing remains but worthless desert.Two thousand years ago a rich and powerful country cut down its trees to build warships， with which to gain itself an empire.It set up the empire but， without its trees， its soil became poor and it grew weak.When the empire fell into pieces， there is nothing left except floods and starvation.What does the author tell us in this passage?

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?

4. 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.The costs of tuition and housing in Lewis and Clark College are ().

5. Passage TwentyAll friendships require a certain amount of chemistry.But when two people of the opposite sex become friends， sometimes those friendly feelings can start to resemble something more like sexual tension.Male-female friendships can be an emotional minefield of hidden desires.Does this mean you secretly want to jump into bed with all of your friends? Of course not.But do you ever wonder how many of them might be interested if the opportunity presented itself? Maybe you and your platonic (柏拉图式的)friendship are just a bad breakup and a bottle of wine away from crossing that boundary and hooking up (结合).So can two people of the opposite sex ever really be “just friends?” The Hollywood answer to this age-old question is a decisive HELL NO.On screen， male-female friendships always turn into something more.Harry and Sally， Chandler and Monica， Jim and Pam…… Do I need to go on? Even the characters in Just Friends wind up becoming much more than the film’s definitive title suggests.Cinematic stories dictate that when reasonably attractive men and women befriend one another， they are always on the road to romance， whether they realize it or not.But how much truth is there to this friendship as foreplay theory? It is not a whole lot.Real life isn’t a romantic comedy.Men and women go to school together， work together and hang out in plenty of platonic settings without falling hopelessly in love with one another.Last year， a close female friend of mine moved in with a new male roommate.My immediate reaction was， “You two are definitely going to sleep together.” It seemed to me that a single man and woman living under the same roof would inevitably end up doing it.Much to my surprise， the roommate romance never happened.Almost one year later， the two of them have never even come close to seeing each other naked.Instead， their way of life has come to resemble a sexless marriage.They cook for each other， argue over domestic chores and insist that they never， ever think about each other “that way.”In the last paragraph， the man and the woman ().
