5. Passage Thirty-FiveTelevision has changed the lifestyle of people in every industrialized country in the world.In the United States， where sociologists have studied the effects， some interesting observations have been made.Television， although not essential， has become an important part of most people’s lives.It alters people’s ways of seeing the world; in many ways， it supports and sustains (维持)modern life.Television has become a baby-sitter， an introducer of conversations， the major transmitter of culture and a keeper of tradition.Yet when what can be seen on TV in one day is critically analyzed， it becomes evident that television is not a teacher but a sustainer; the poor quality of programming does not elevate (提高)people into greater understanding， but rather maintains and encourages the life as it exists.The primary reason for the lack of quality in American television is related to both the history of TV programming development and the economics of TV.Television in America began with the radio.Radio companies and their sponsors first experimented with television.Therefore， the close relationship which the advertisers had with radio programs became the system for American TV.Sponsors not only paid money for time within programs， but many actually produced the programs.Thus， in American society， television is primarily concerned with reflecting and attracting society rather than experimenting with new ideas.Advertisers want to attract the largest viewing audience possible.To do so requires that the programs be entertaining rather than educational， attractive rather than challenging.Television in America today remains， to a large extent， with the same organization and standards as it had thirty years ago.The hope for further development and true achievement toward improving society will require a change in the entire system.The author’s attitude towards American television is ().

36. Questions 36 to 40 are based on the following passage.Most of us in the entrepreneurial community are blessed — or cursed — with higher-than-average ambition.Ambitious people strongly desire accomplishments and are willing to take more risks and spend more effort to get them.Overall， this is a positive quality， especially for people trying to build their own businesses.Apparently， if you’re more naturally driven to set goals， you are more likely to succeed.Actually， this isn’t always the case.In fact， in some cases， extreme ambition may end up doing more harm than good.One major side effect of excessive ambition is the tendency to focus too determinedly on one particular vision or end goal.This is problematic because it hinders your ability to adapt to new circumstances， which is vital if you want to be a successful entrepreneur.If a new competitor emerges to threaten your business， you may need to change direction， even if that means straying from your original vision.If you have too much ambition， you’ll find this hard， if not impossible.Few people are successful when they try to build their first brand.Unfortunately， for the most ambitious entrepreneurs， a failure is seen as disastrous， and impossible to recover from.It’s a clear departure from the intended plan toward the intended goal.For people with limited ambition， however， failure is viewed as something closer to reality.Remember， failure is inevitable， and every failure you survive is a learning experience.Ambitious people tend to be more materialistically successful than their non-ambitious counterparts.However， they’re only slightly happier than their less-ambitious counterparts， and tend to live significantly shorter lives.This implies that even though ambitious people are more likely to achieve conventional “success，” such success means nothing for their health and happiness—and if you don’t have health and happiness， what else could possibly matter?Clearly， some amount of ambition is good for your motivation.Without any ambition， you wouldn＇t start your own business， set or achieve goals and get far in life.But an excess of ambition can also be dangerous， putting you at risk of burnout， stubbornness and even a shorter life.What does the author think of most entrepreneurs?

B. 　They are more ambitious than ordinary people.

C. 　They achieve greater nonconventional success.

D. 　They have more positive qualities than most of us.

4. 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.Why does land become desert after all trees are cut down?

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 ().
