After moving to the United States, immigrant group
s trying to fit in tend to choose high calorie fatty foods in an attempt to appear more American，a new study finds．That's one reason why immigrants approach US levels of obesity within 15 years of moving to America．
The researchers also did an experiment that measured whether or not the threat of appearing un-American influenced respond
ents' food choices．After being questioned about their ability to speak English，75 perce
nt of Asian-Americans identified a typical American food as their favorite. Only 25 percent of Asian-Americans who had not been asked if they spoke English did the same.
When their American identity was called into question during a follow-up study, Asian-American participants also tended to choose typical American dishes，such as hamburgers and cheese sandwiches．In that experiment, 55 Asian-Americans were asked to choose a meal from a local Asian or American restaurant. Some participants were told that only Americans could participate in the study. Those who chose the more typical American fare ended up consuming an extra 182 calories，including 12 grams of fat and 7 grams of saturated fat（饱和脂肪）.
"People who feel like they need to prove they belong to a culture will change their habits in an attempt to fit in，"said Sauna Cheryan，an author of the study and assistant professor of psychology at the University of Washington." If immigrants and their children choose unhealthy American foods over healthier traditional foods across their lives，this process of fitting in could lead to poorer health." Cheryan added．
Social pressures，the study concluded, are at the heart of the problem．"In American society today, being American is associated with being white．Americans，who don't fit this image even if they were born here and speak English，feel that pressure to prove that they're American," said Cheryan．The author wants to show that __________.

The way people hold to the belief that a fun - filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment （预担的义务）, self - improvement.
Ask a bachelor（单身汉） why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.According to the author, a bachelor resists marriage chiefly because ________ .
| A．he is reluctant to take on family responsibilities |
| B．he believes that life will be more cheerful if he remains single |
| C．he finds more fun in dating than in marriage |
| D．he fears it will put an end to all his fun adventure and excitement |
Raising children, in the author’s opinion is ________ .
| A．a moral duty | B．a thankless job |
| C．a rewarding task | D．a source of inevitable pain |
From the last paragraph, we learn that envy sometimes stems from ________ .
| A．hatred | B．misunderstanding | C．prejudice | D．ignorance |
To understand what true happiness is one must ________ .
| A．have as much fun as possible during one’s lifetime |
| B．make every effort to liberate oneself from pain |
| C．put up with pain under all circumstances |
| D．be able to distinguish happiness from fun |
What is the author trying to tell us?
| A．Happiness often goes hand in hand with pain． |
| B．One must know how to attain happiness. |
| C．It is important to make commitments. |
| D．It is pain that leads to happiness. |
America is growing older. Fifty - eight years ago, only 4 out of every 100 people in the United States were 10 or older. To day, 10 out of every 100 Americans are over 10. The aging of the population will affect（影响）American society in many ways—education, medicine, and business. Quietly, the graying of America has made us a very different society—one in which people have a quite different idea of what kind of behavior（行为） is suitable（合适）at various , ages.
A person s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29 - year - old university president or a 35 - year -old grandmother, or a 15 year - old man who has become a father for the first time. Public ideas are changing.
Many people say, “I am much younger than my mother— or my father— was at my age. ”No one says“Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.
12．It can be learnt from the text that the aging of the population in America ________ .
A. has made people feel younger B. has changed people’s social position
C. has changed people’s understanding of age D. has slowed down the country’s social development
13．The underlined word “one”refers to ________ .
A. a society B. America C. a place D. population
14．” Act your age” means people should ________ .
A. be active when they are old
B. do the right thing at the right age
C. show respect for their parents young or old
D. take more physical exercise suitable to their age
15．If a 25 - year - old man becomes general manager of a big firm, the writer of the text would most probably consider it ________ .
A. normal B. wonderful C. unbelievable D. unreasonable

A device that stops drivers form falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.According to the text, Driver Alert ______.
| A．aims to reduce tiredness-related accidents |
| B．has gone through testing at laboratories |
| C．aims to prevent drivers form sleeping |
| D．has been on sale for 12 months |
How should a driver respond to the sounds from Driver Alert?
| A．By sounding a warning. | B．By touching the wristband. |
| C．By checking the driving time. | D．By pressing the steering wheel. |
We can learn form the text that the driver needs to stop for a break when his response time is ______.
| A．about 400 milliseconds | B．below 500 milliseconds |
| C．over 500 milliseconds | D．about 4 minutes |
When the driver gets sleepy while driving, Driver Alert ______.
| A．moves more regularly | B．stops working properly |
