Some analysts suggest that in recent years many people are less patient because of technology.They suggest that “digital technology, from cellphones to emails to Wads, is changing our lives.The instant results we get from this technology have in turn increased our desire for instant satisfaction in other aspects of our lives.”
Psychologist Jennifer Hartstein makes some observations.She explains that “we have become an immediate satisfaction culture, and we expect things to move quickly, efficiently and in the way we want.When that doesn't happen, we tend to become increasingly frustrated and unsatisfied.”
Some believe that e-mail is losing popularity and could soon become outdated.Why？ Because many people who send messages do not have the patience to wait hours, or even minutes, for a response.Also, with e-mails, as with letter writing, introductory and concluding greetings are often expected.But many people consider such formalities(客套)to be boring and time-consuming.They prefer instant messaging.Many people do not take the time to proofread what they put in writing.As a result, letters and e-mails contain numerous grammatical and spelling errors.
The thirst for immediate results is not limited to the digital communications.People seem to be losing their ability to wait in other areas of life.For instance, do you ever find yourself talking too fast, eating too fast, driving too fast, or spending money too fast？ The few moments it takes to wait for an elevator to come, for a traffic light to change, or for a computer to start may seem like too long a time.
16.According to the first paragraph, people ______.
A.were more patient in the past

D.used to be patient while waiting in line
17.Nowadays people lose their patience because（）.
A.their desire for satisfaction has increased
B.they are bored with what they have
C.they have more things to do than before
D.their life has been changed by technology
18.Some believe that e-mail could soon become outdated because ______.
A.it takes a long time to start the computer
B.people value formalities between friends
C.people can hardly wait for a response
D.cellphones are more popular nowadays
19.The pursuit of instant results causes people to ______ .
A.become more impolite
B.have more errors in their writings
C.use voice messages instead of emails
D.lose many of their abilities in life
20.The best title for the passage might be “______”.
A.What Are the Problems Caused by Impatience
B.Are We Less Patient Today
C.What Happened to Technology
D.Has Digital Technology Changed Our Lives
What is it about a dog's gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin.Oxytocin is a substance in the blood that encourages bonding.Levels of oxytocin increase, for example, when a mother feeds her newborn baby.According to Nagasawa's study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs.It all started somewhere tens of thousands of years ago.Scientists believe that wolves used to follow humans who were hunting large animals.The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change.They became more loyal to their human partners.The wolves and humans started to depend on each other and bond with each other.These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them.And according to Nagasawa's study, this bond was formed with the help of oxytocin, the cuddle chemical.
11.What do we know about oxytocin？()
A.It regulates blood flow
B.It promotes bonding
C.It is in the human gene
D.It is good for health
12.When we look deeply into a dog's eyes, the levels of our oxytocin ____.
A.reduce over time
B.go either up or down
C.are on the rise
D.remain unchanged
13.At the beginning wolves followed humans to ____.
A.eat the food left by humans
B.guard against large animals
C.take humans for food
D.hunt large animals together
14.Over time some wolves turned into dogs ____.
A.due to their loyalty
B.due to the changing environment
C.for better survival
D.for better cooperation
15.What does Nagasawa9s study aim to do？()
A.Explore the role of human-wolf partnership
B.Show the characteristics of the cuddle chemical
C.Explain the bond between humans and dogs
D.Understand the evolution of species
You were probably right if you thought that was caused by a lack of sleep.Dr.Home, a sleep researcher in England, studied 24 college students.One group got their normal eight hours of sleep.The other group didn’t get the smallest amount of sleep — they stayed awake all night.The next day, Dr.Home tested the students.He asked them questions that required creative and original thinking.One of the questions was “How many uses can a cardboard box be put to？”
The results？ The wide-awake students did well on the tests.The tired students did poorly.
Research has already shown that tired people can do okay on tests of routine thinking, like simple addition.But Dr.Home tested creative thinking only.
As part of his study, he offered an amount of money as a reward to the sleepy students if they did well.But even this encouragement wasn’t enough to help the students overcome their tiredness.They still did poorly.Dr.Home believes that the cerebral cortex — the part of the brain where thinking takes place — may get worn out during waking hours.Sleep may help to repair the brain overnight.Without any sleep, he emphasizes, “even if you concentrate harder, you cannot do better.”
This study gives people something to think about, especially people like hospital workers and airline pilots, who must stay awake all night and then make emergency decisions.
36.According to the passage, the confusion of your mind is possibly due to _____.

D.telling other people their names
38.The purpose for Dr.Home to offer a lot of money to the sleepy students is to _____.
A.help them repair their brains

The original Americans, of course were the Indians.The so-called white men who then came were mostly from England.But many came from other countries like Germany and France.
One problem the United States has always had is discrimination.As new groups came to the United States, they found they were discriminated against.First it was the Irish and Italians.Later it was the blacks.Almost every group has been able to finally escape this discrimination.The only immigrants who have not are the blacks.Surprisingly enough the worst discrimination today is shown towards the Indians.
One reason the Indians are discriminated against is that they have tried so hard to keep their identity.Of course they are not the only ones who have done so.The Japanese have their Little Tokyo in Los Angeles and the Chinese a Chinatown in New York.The Dutchsettlement in Pennsylvania also stays separate from other people.Their towns are like something from the 19th century, They have a different reason from the other groups for staying separately.They live separately for religious reasons rather than keep together in a racial group.
Although some groups have kept themselves separate and others have been discriminated against, all groups have helped make the United States a great country.There is no group that has not helped in some way.And there is no group that can say they have done the most to make it a great country.
Many people still come from other countries to help the United States grow.A good example is the American project that let a man walk on the moon.It was a scientist from Germany who was most responsible for doing that.It is certain that in the future the United States will still need the help of people from all racial groups to remain a great country.

Two American inventors, Alexander Graham Bell and Elisa Gray, succeeded at almost the same time. The United States Supreme Court finally had to decide which of the two was the first inventor of the telephone. The Court decided 37 Bell’s favor.
Born in Edinburgh, Scotland, Bell grew up in a family that was very interested in teaching people to speak. His grandfather had been an actor who left the theatre to teach elocution(演讲技巧); his father was a teacher 38 deaf-mutes learn how to speak.
However, probably none of the later inventions gave Bell the same feeling of success __39_ he had on the day when he spilled some acid from his batteries. It was after he had worked for months to find ways to send something more than metallic twangs(金属砰弦声)over the wires. Thinking Watson, __40__, was in the next room, Bell called, "Mr. Watson, come here. I want you." Watson was not in the next room. He was down in his laboratory, next to the receiver. To Watson's surprise, he heard the words perfectly. He ran to tell Bell the news: the wires had carried Bell's voice perfectly.

Satellites have enabled immediate reporting worldwide.A reporter can send the news to a network like CBS News and within seconds it can be all over the world.They send electronic reports that go straight into the newspaper or onto the TV screen.Reporters can now also transmit images through their mobile phones.Consequently, live, “on-the-spot” reporting has become the norm and TV viewers can get a much better idea of what a natural disaster, a conflict or an interesting scientific discovery is like.
In recent years, several changes have occurred in the ownership of news media.Networks owned by large companies and governments have become bigger and very powerful.These networks – such as BBC News 24–are hungry for news and have huge audiences.However, there can only be a limited number of such networks and their ownership is a big issue.
Some companies not only own TV and radio networks but newspaper groups as well.Who decides what news to publish and what sort of “spin” to put on it？ Is it always objective？ There are now “spin doctors” who manipulate the news,emphasising certain parts and not others – and as a result, much of it is not neutral.Therefore, the question of control of the media matters very much.In some cases, the media companies are more powerful than governments.They can even influence elections.So the question is – should they be controlled and if so, by whom？

Comfort with food. When diet expert Judith Wurtman is stressed out, she does what a lot of people do this time of year: she reaches for food .But in her case, it’s a healthy rice cake or two. “My research suggests that carbohydrates (碳水化合物) raise levels of a brain chemical, which has a calming effect on the entire body,” says the MIT research scientist. “So signs of stress — such as anger, tension, and inability to focus — are eased.”
Run from your problems. Dr. Kenneth H. Cooper, who popularized aerobics (有氧运动) through his1968 book by that name, handles his own stress with a daily after-work run. He knows that physical activity reduces anxiety and depression. “Aerobic exercise is the best way to dissipate stress,”says Cooper.
Look to the light side. On his way to the hospital where his father was to have surgery Joel Goodman shared a hotel bus with anxious relatives of several patients. The driver began telling his stressed-out passengers a few jokes. “Then he did some magic tricks that had my mother and me laughing.” Goodman says. “In that five-minute ride he taught us that humor can lessen our stress.”
The surgery was successful, and Goodman was so moved by his experience that he researched laughter’s power. “A good laugh relaxes muscles, reduces blood pressure, restrains stress-related hormones and enhances the immune system (免疫系统),” he says.
Go green. Coffee, loaded with hidden sources of caffeine, stimulates (刺激) the nervous system and can make you feel stressed more easily. That’s why Arizona Doctor Andrew Weil, author of best seller Spontaneous Healing, does not take caffeine. “When I want gentle energy, I drink green tea. It contains a caffeine-like element”, Weil says. It also contains compounds that, some studies suggest, have anti-cancer effects.
16. The following are ways to free you from stress EXCEPT__________.
A. looking at things in a more relaxed way
B. getting a lot of sleep during the day
C. eating some food with carbohydrates
D. doing some aerobic exercise

C. enhance the immune system D. take a holiday
19. What is the meaning of the word “dissipate” in the part “Rum from your problems”？
A. lessen. B. Depress. C. Disturb. D. Level.
20. Which of the following group of people can have a happier life, according to passage？
A. Those who are continuously eating something.
B. Those who are always engaged in working.

and twelve million golfers.These figures would not surprise most people.But many would be surprised to learn that twenty million Americans ride motorcycles (摩托车).Few people realize that motorcycling is fast becoming one of America’s most popular sports.
According to the Cycle News，many kinds of people enjoy motorcycling.They include black people and white people, businessmen, professionals, and blue-collar workers.Among them, about 55% are businessmen, 3% are in the professions and 9% in government service.
Such information is offered by the Cycle News in the hope of improving the general public’s impression of the sport.The public has tended to believe that all motorcyclists are wild and lawless young men.
There are several things about motorcycling that the average citizen dislikes.A motorcyclist’s appearance has something to do with this dislike.Motorcyclists often look dirty; in fact, they are dirty.On the road, there is little to protect them from mud.For practical reasons, they often dress in old clothing which looks much less respectable than the clothing of people who ride in cars.For the same reason, motorcyclists usually wear dark colors.Perhaps this helps to explain why they are sometimes suspected of having bad natures.
Probably motorcycles themselves also produce anger and fear.They are noisy， though some trucks are even noisier.But trucks are acceptable because they perform. a needed service.Motorcycles, on the other hand, make an uncomfortable noise just to give their riders pleasure.Roaring along quiet streets, they wake sleeping families and make babies cry.
Yet, as motorcycling becomes more and more common, it will be interesting to see how people in general feel about the sport.Perhaps it will someday become as “respectable” as tennis or golf.

The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals, and whether or not they felt a significant amount of control over their ability to be successful. Overwhelmingly, the results show that today， the idea of the American dream—and what it takes to achieve it—looks quite different than it did in the late 20th century.
By and large, people felt that their actions and hard work—not outside forces—were the deciding factor in how their lives turned out. But respondents had decidedly mixed feelings about what actions make for a better life in the current economy.
In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority—52 percent—think that young people do not need a four-year college education in order to be successful.
Miguel Maeda, 42, who has a master's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did.
While some, like Maeda, emphasized the value of the degree rather than the education itself, others still see college as a way to gain new perspectives and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, thinks "personal drive" is far more important than just going to college. To Fendley， a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America.
71.It used to be commonly acknowledged that to succeed in America, one had to have _____.
A.an advanced academic degree
B.an ambition to get ahead
C.a firm belief in their dream
D.a sense of drive and purpose
72.What is the finding of the latest National Journal poll concerning the American dream____
A.More and more Americans are finding it hard to realize.
B.It remains alive among the majority of American people.
C.Americans' idea of it has changed over the past few decades.
D.An increasing number of young Americans are abandoning it.
73.What do Americans now think of the role of college education in achieving success____
A.It still remains open to debate.
B.It has proved to be beyond doubt.
C.It is no longer as important as it used to be.
D.It is much better understood now than ever.
74.How do some people view college education these days____
A.It promotes gender equality.
B.It needs to be strengthened.
C.It adds to cultural diversity.
D.It helps broaden their minds.
75.What is one factor essential to success in America, according to Will Fendley____
A.A desire to learn and to adapt.
B.A strong sense of responsibility.
C.A willingness to commit oneself.
D.A clear aim and high motivation.
