18.A 17-year-old boy,caught sending text messages in class,was recently sent to the vice principal's office.The vice principal,Steve Gallagher,told the boy he needed to focus on the teacher,not his cellphone.The boy listened politely and nodded,and that's when Mr.Gallagher noticed the student's fingers  moving on his lap.He was testing while being scolded for texting."It was a subconscious act,"says Mr.Gallagher,who took the phone away."Young people today are connected socially from the moment they open their eyes in the morning until they colse their eyes at night.It's compulsive."
A study this year by psychology students at Covenant College in Lookout Mountain,Ga.,found that the more time young people spend on Facebook,the more likely they are to have lower grades and weaker study habits.Heavy Facebook users show signs of being more sociable,but they are also more likely to be anxious,hostile or depressed.(Doctors,meanwhile,are now laming addictions to‘night texting'for disturbing the sleep patterns of teens.)
Almost a quarter of today's teens check Facebook more than 10 times a day,according to a 2009 survey by Common Sense Media,a nonprofit group that monitors media's impact on families.Will these young people get rid of this habit once they enter the work force,or will employers come to see texting and‘social-network checking'as accepted parts of the workday?
Think back,When today's older workers were in their 20s,they might have taken a break on the job to call friends and make after-work plans.In those earlier eras,companies discouraged non-business-related calls,and someone who made personal calls all day risked being fired.It was impossible to imagine the constant back-and-forth texting that defines interactions among young people today.
Educators are also being asked by parents,students and educational strategists to reconsider their rules."In past generations,students got in trouble for passing notes in class.Now students are good at texting with their phones still in their pockets,"says 40-year-old Mr.Gallagher,the vice principal,"and they're able to communicate with someone one floor down and three rows over.Students are just fundamentally different today.They will take suspensions rather than give up their phones."
66.The underlined word"a subconscious act"in the first paragraph refers to an actB        
A.on purpose                                                         
B.without realization
C.in secret                                                               D.with care

A.are good at dealing with the social relationships and concentrate on their study
B.have high spirits and positive attitudes towards their life and work
C.have been influenced mentally in the aspects of behaviors and habits
D.are always in bad mood and have poor performance in every respect
68.Through the situation of today's older workers in their 20s,it can be inferred thatD        
A.the employers will not accept young people's sending text messages
B.a cellphone is a must for today's older workers instead of young people
C.The employers prefer older workers to young  people
D.the employers will find it hard to control the interaction among young people  
69.Mr.Gallagher reminds us that the students in the past and those todayC.
A.like to break rules and have the same means of sending messages
B.are always the big problem for the educations and their parents
C.like sending text messages but those today do it in a more secret and skillful way

1.I log onto a computer at the doctor's office to say I have arrived and then wait until a voice calls me into the examination room.
  There,a robotic nurse directs me onto a device and then takes my blood pressure.Some time later,in steps the doctor,who is also a robot.He notes down my symptoms and gives me a prescription (处方).I pay for my visit using a credit card machine and return home without having met another human being.
  When I call my dentist's office and actually get a human being on the line,I am thrilled.And when I see the introduction of yet more self-service checkout stations at the grocery store,I feel like shouting,"When it comes to cashiers,make mine human,please!"
  After all,human cashiers sometimes give you a store coupon (优惠券) for items you are buying.Even more than that,real-life cashiers often take an interest in particularly cute children,which can brighten a young mother's day.A cashier may also show compassion (同情)for an elderly person struggling to get that last penny out of her purse.
  What technological device would do any of this?I don't want to go back to the Stone Age,but I'm also worried about a world run by machines.Sometimes when you're chatting with someone,you discover things you need to know.Maybe a receptionist needs prayers said for a sick child.Maybe a salesperson can offer a bit of encouragement to a customer who is feeling tired.
  Machines can be efficient and cost-effective and they often get the job done just fine.But they lack an element so important to everyday life.
  Call it the spirit,the soul or the heart.It is something no machine will ever have.It is being human that encourages us to smile at others,which may be what they need at that moment.

6.The poverty line is the minimum income that people need for an acceptable standard of living.People with incomes below the poverty line are considered poor.Economists study the causes of poverty in order to find solutions to the problem.
As the general standard of living in the country rises,the poverty line does,too.Therefore,even with today's relatively high standard of living,about 10percent of the people in the United States are below the poverty line.However,if these people had stable jobs,they could have an acceptable standard of living.Economists suggest several reasons why poor people do not have jobs.
For one thing,more than half of the poor people in the United States are not qualified to work.Over 40percent of the poor people are children.By law,children less than 16years old cannot work in many industries.And over 10percent of the poor people are old.Many companies do not hire people over 65years old,the normal retirement age.
Some poor adults do not look for jobs for a variety of personal reasons:they are sick,they do not have any motivation (动力),they have family problems,or they do not believe that they can find a job.
Other poor people look for a job but cannot find one.Many poor adults never went to high school.Therefore,when they look for jobs,they have few skills that they can offer.
At the present time,the government thinks it can reduce poverty in the country in the following ways.
First,if the national economy grows,businesses and industries hire more workers.Some of the poor who are qualified to look for jobs may find employment.Then they will no longer be below the poverty line.
Second,if society invests in the poor,the poor will become more productive.If the government spends money on social programs,education,and training for poor people,the poor will have the skills to offer.Then it is more likely that they can find jobs.
Finally,if the government distributes society's income differently,it raises some poor people above the poverty line.The government collects taxes from the non-poor and gives money to the poor.These payments to the poor are called welfare.In 2010over 18million people in the United States received welfare.
Some economists are looking for better solutions to the poverty problem.However,at the present time,many people depend on welfare for a minimally acceptable standard of living.

(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
81.What does the poverty line in a country change with?The general standard of living.
82.Most of the American poor people are not qualified for employment becausethey are too young or too old(towork).
83.In order for the poor to have the skills to offer,the government must invest insocial programs,education,and training for poor people.
84.How do those below the poverty line enjoy the existing welfare from the government?

13.In the past few decades,the popular belief in the area of organizational behaviour and organizational psychology has been that happy workers are better workers.However,new research at the University of Alberta shows that sad workers are more productive.
Psychologist Dr.Robert Sinclair and his former PhD student Carrie Lavis recently conducted a series of four studies addressing the effects of experimentally induced (诱发的) happiness versus sadness on work productivity by asking the participants to build circuit boards (电路板).In the first study,sad people committed significantly fewer errors than did happy people (approximately half the number of errors) but there was no difference in the number of boards completed.Thus,sad people were more productive.
In similar studies Sinclair and Lavis found the same results along with evidence that happy people might not devote as much energy to the task in order to maintain their happy moods-they considered that task as something that might detract (减去) from their present feelings.Conversely,sad people appeared to be devoting energy to the task in order to divert themselves from their sad feelings."It is important to know that the moods were unrelated to the task,"said Sinclair."Unhappiness is coming from something else."
These findings are not surprising,said Sinclair,since there has been a growing body of literature in the area of social psychology demonstrating that sad moods lead to more calm lengthy intent consideration and,often,more thoughtful or accurate judgments.
In Sinclair's following studies,when people believed that the task would make them feel good,they devoted more energy to the job.The bottom line,said Sinclair,is that it is important for organizations to take into account the emotions of their employees.It seems it could be beneficial to creating situations that lead people to believe that performing their jobs will cause them to feel good:this could cause increases in motivation and superior performance.

72.The new research done at the University of Alberta showsC.
A.sadness leads to accurate judgments 
B.sad workers are less engaged in their work
C.sad workers produce better 
D.happiness can make people do well
73.The purpose of the series of four studies conducted by Dr.Sinclair wasA.
A.to find out the influence of happiness vs.sadness on work
B.to ask the subjects to build circuit boards
C.to prove that happy workers are better workers
D.to explore the ways how to produce happiness or sadness at work
74.According to the third paragraph,the happy workers might not devote as much energy
to the task becauseD.
A.they hate doing the same job for a long time
B.they never feel sad
C.happiness diverts them from their task
D.they want to keep their happy moods
75.It is suggested in the last paragraph thatB.
A.increases in motivation and superior performance are important
B.companies should take into consideration employees'emotions
C.companies should create situations that make workers feel good
D.employees should do the task that would make them feel good.

7.The meaning of the word"Volunteer"may be a little different in different countries,but it usually means"one who offers his or her services."There are many different ways in which people can volunteer,such as taking care of sickpeople,working in homes for homeless children,and picking up garbage from beaches and parks.Volunteers may work within their own countries or in other countries.They areoften people with a strong wish to help those who are less fortunate than themselves.Volunteers don't expect any kind of pay.
At the root of volunteering is the idea that one person may have the ability to offer services that can help other people.Tracy,a good friend of mine,however,recently came back from India with a new idea of what being a volunteer means.She worked for two and a half weeks in one of Mother Teresa's homes in Calcutta.The following is her story.
"I first heard about Mother Teresa in my high school,we watched a video about her work in India and all over the world.I was so moved by her spirit to help others and her endless love for every human being that after I graduated from high school,I too wanted to try her kind of work.So with two friends I flew to Calcutta for a few weeks."
"I was asked to work in a home for sick people.I helped wash clothes and sheets,and pass out lunch.I also fed the people who were too weak to feed themselves and tried to cheer them up.I felt it was better to share with them than to think that I have helped them.To be honest,I don't think I was helping very much.It was then that I realized that I had not really come to help,but to learn about and experience another culture that helped improve my own understanding of life and the world."
32.According to the passage,a volunteer refers to a person whoA
A.is willing to help ose in need without pay.
B.can afford to travel to different places.
C.has a strong wish to be successful.
D.has made a big fortune in life.
33.Tracy started her work as a volunteerB.
A.after she met Mother Teresa.
B.after she finished high school.
C.when she was touring Calcutta.
D.when she was working in a hospital.
34.Why did Tracy choose to be a volunteer?D
A.She liked to work with Mother Teresa.
B.She had already had some experience.
C.She was asked by Mother Teresa's example.
D.She wanted to follow Mother Teresa's example.
35.What is Tracy's"new idea"(Paragraph 2)of being a volunteer?D

B.Working in Mother Teresa's home.
C.Doing simple things to help the poor.

8.Kong zi,also called Confucius(551-479B.C),and Socrates (469-399B.C) lived only a hundred years apart,and during their lifetimes there was no contact between China and Greece,but it is interesting to look at how the world that each of these great philosophers came from shaped their ideas,and how these ideas in turn,shaped their societies.
Neither philosopher lived in times of peace,though there were more wars in Greece than in China.The Chinese states were very large and feudal,while the Greek city-states were small and urban.The urban environment in which Socrates lived allowed him to be more radical(激进的) than Confucius.Unlike Confucius,Socrates was not asked by rules how to govern effectively.Thus,Socrates was able to be more idealistic,focusing on issues like freedom,and knowledge for its own sake.Confucius,on the other hand,advised those in government service,and many of his students went out to government service.
Confucius suggested the Golden Rule as a principle for the conduct of life:"Do not do to others what you would not want others to do to you."He assumed that all men were equal at birth,though some had more potential than others,and that it was knowledge that set men apart.Socrates focused on the individual,and thought that the greatest purpose of man was to seek wisdom.He believed that some had more potential to develop their reason than others did.Like Confucius,he believed that the superior class should rule the inferior (下层的) classes.
For Socrates,the family was of no importance,and the community of little concern.For Confucius,however,the family was the center of the society,with family relations considered much more important than political relations.
Both men are respected much more today than they were in their lifetimes.
29.Which of the following is TRUE according to the first paragraph?C
A.Socrates and Confucius had much in common.
B.Confucius had much influence on Socrates'ideas.
C.The societies were influenced by the philosophers'ideas.
D.There were cultural exchanges between China and Greece.
30.What made some people different from others according to Confucius?C
A.Family     
B.Potential     
C.Knowledge      
D.Community
31.Socrates shared with Confucius the idea thatB.
A.all men were equal when they were born
B.the lower classes should be ruled by the upper class
C.the purpose of man was to seek freedom and wisdom
D.people should not ask others to do what they did not want to
32.This passage is organized in the pattern ofB.
A.time and events                       
B.comparison and contrast
C.cause and effect                       
D.definition and classification.
