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.

2. Passage SeventeenNo one knows how man learned to make words.Perhaps he began by making sounds like those made by animals.Perhaps he grunted like a pig when he lifted something heavy.Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground.Somehow， he learned to make words.As the centuries went by， he made more and more new words.This is what we mean by language.People living in different countries made different kinds of words.Today there are about fifteen hundred different languages in the world.Each contains many thousands of words.A very large English dictionary， for example， contains four or five hundred thousand words.But we do not need all these.Only a few thousand words are used in everyday life.The words you know are called your vocabulary.You should try to make your vocabulary bigger.You’re supposed to read as many books as you can.There are plenty of books written in easy English for you to read.You will enjoy them.When you meet a new word， you should find it in your dictionary.Your dictionary is your most useful book.The number of different languages spoken is about ().

40. 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 advise us to do concerning ambition?

A. 　Distinguish between conventional success and our life goal.

B. 　Follow the example of the most ambitious entrepreneurs.

C. 　Avoid taking unnecessary risks when starting a business.

D. 　Prioritize health and happiness over material success.

2. Passage Thirty-TwoHave you ever heard of a pawpaw (木瓜)? If not， do not feel bad.Many Americans do not know of the fruit， although it is native to the U.S.Once， however， it was one of the most popular fruits in North America.Happily， those who love the pawpaw are trying to return it to its former position in American foods.A pawpaw is a tropical fruit that used to be grown along the East Coast from New York to Florida and all over the eastern U.S.At one time， it could be found as far west as Nebraska.The pawpaw was an important food for Native Americans and even early European settlers.Pawpaws reportedly were a favorite treat of George Washington， the first U.S.president， who especially liked them cold.Thomas Jefferson， the third U.S.president， was also a fan of the fruit.He planted pawpaws at his home in Virginia.He also sent pawpaw seeds to his friends in France.American explorers Lewis and Clark wrote in their journals about the pawpaw.The pawpaw is difficult to be sold commercially.The fruit requires a very special environment—low， wet areas that sometimes flood.It has a very short harvest season， from two to three weeks in September and October.In addition， the fruit is good to eat for only two to three days after harvesting.This makes it hard to sell anywhere distant from the pawpaw tree it comes from.Planters are again growing pawpaw trees and harvesting the fruit.In several states farmers have organized “pawpaw festivals” to reintroduce people to food.At such a festival in Maryland recently， farmers displayed different products made with pawpaws， like pawpaw jams， pies， ice-cream and beer.The pawpaw used to be found mainly ().

3. Passage Twenty-FourSocial change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways.The simple reason for this is that there are more different ways of looking at things present in the first kind of society.There are more ideas， more disagreements in interest， and more groups and organizations with different beliefs.In addition， there is usually a greater worldly interest and greater tolerance in mixed societies.All these factors tend to promote social change by opening more areas of life to decision.In a society where people are quite similar in many ways， there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same.And although conditions may not be satisfactory， they are at least customary and undisputed.Within a society， social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material， for example， in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.Furthermore， social change is easier if it is gradual.For example， it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies (一分为二).This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts”.According to the passage， which of the following is NOT true?

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?
