10.For young people,friends are often determined by their being close.Whoever is around is your friend.As humans get older,they become more selective (講究的) in choosing whom they spend time with,as well as how they spend their time.According to a new study,the same goes for monkeys.The findings,in the journal Cell Biology,suggest human selectivity may be a very strong part of our evolutionary history (進化史).
"An important finding suggests that humans become more socially selective when they know that their remaining life time is limited,such as in old age,"Professor Laura Almeling explained."We don't think that monkeys are aware of their own limited future time.Therefore,if they show similar changes in old age,their selectivity cannot be attributed to their knowledge about a limited future time,"she continued.
Researchers showed a variety of new animal toys,only one of which included a food treat,to a group of African monkeys.Young monkeys quickly grew out of their interest in the toys,preferring only the object that included food once they grew up.
Researchers also measured how monkeys'social activities change as they age,by watching and measuring their responses to pictures and sounds of friends.
Although older monkeys still took part in and remained interested in group activities,they put less time and energy into social relationships."With increasing age,the monkeys became more selective in their social activities,"Almeling said."They had fewer‘friends'and put less time into social activities.Interestingly,however,they were still interested in what was going on in their social world.Older females continued to respond particularly strongly to hearing a scream for help from their best friend,"Almeling explained."Older males still liked to look at pictures of the newborns,"she said.

32.What has the new study found?C
A.Humans have many things in common with monkeys.
B.Monkeys become closer to each other as they get older.
C.Monkeys get more selective as they get older.
D.Humans choose friends more seriously when they are older.
33.What happens to monkeys as they get older?A
A.They choose friends and social activities more carefully.
B.Their knowledge about their future time grows.
C.They become aware that they have little time left.
D.They show more interest in food.
34.What can the underlined words be replaced by?C
A.Be devoted to     B.Be helpful to       C.Be caused by      D.Be aware of
35.Female monkeysB their friends'screams for help when they are old.
A.put less time and energy into
B.still have a strong response to
C.change social reactions to
D.don't show interest in.

7.One spring,when I was 10,during one of my father's layoffs (失業(yè)),I could tell my mother was unhappy.I decided to cheer her up by buying her a special Mother's Day gift.
One day after school I rode my bike to the Agins,which,I learned years later,was known for its high-end fashions (時尚) and styles.I introduced myself to Sylvia Agins,telling her I was looking for a Mother's Day present.
"Do you think she'd like a purse?"she asked.I told her.I thought she might.
She took out an Italian handbag made of leather.She asked me what I thought,and I told her that my mom would like it.
"How much money do you have?"she asked.
"Twelve dollars,"I said.
"You're in luck,"she told me."It's only﹩11.You have a dollar left over for the card."She gift-wrapped the purse and thanked me for my business,and I rode off home with the package under my arm.
When my mother opened the gift the next Sunday morning,she asked in an accusing tone,"Where did you get this?"
"I bought it at the Agins.It cost me﹩11."I said.
My mother was shocked into silence.
It wasn't until many years later,when I learned that the purse was worth several hundred dollars,that I appreciated just how wonderful Sylvia Agins had been to me.I always felt bad that I never had a chance to properly thank her.
"You know,my son,what really amazes me to this day,"my mother said,"Letting you have the purse for just a few dollars was unbelievable enough.But the fact that she let you leave the store with a dollar for the card was a touch of kindness that I'll never forget."

1.Third Culture Kids
As more cities and companies become increasing international,there is a growing number of children that are creating their own sub-culture.Often (36)A to as TCKs (Third Culture Kids) or Global Nomads,these students have a(n) (37)B impact on the global community.
So who are these Third Culture Kids?They are not a new phenomenon.As one looks(38)B history,there is a realization that certain groups of people have led highly (39)C lives,a key(40)D in describing TCKs.They often(41)C their parents into another country and spend a significant part of his or her development years outside the parents'culture.They are(42)A to new cultures and to other people in the community who (43)D move constantly.Their numbers (44)B into the hundreds of thousands and are increasing.Ease of (45)D and constant relocation of people through multinational companies and global business links contribute to this (46)A.
The question"Who am I?"is frequently asked by TCKs.They have (47)B a host of cultural identities,and have built relationships to all the cultures,(48)C not having full ownership of any.Although elements from each culture are absorbed into TCK's life experience,the sense of (49)D is in relationship to others of a similar background.
As you enter into the world of TCKs,one might suspect they are no(50)C.But it is (51)A,after spending only a short time with them,that they bring a deep knowledge from inside and a special ability to compare(52)B and local issues.They represent many countries and cultures.They are the future cross-culturalists and (53)A future politicians,diplomats,government employees and educators.
They certainly experience a different lifestyle compared to their mono-cultural peers but we can benefit from their global and (54)C lives.So,whatever one chooses to label the international students as---TCKs,Global Nomads,or Global Souls---we will gain unbelievable (55)D.

15.In many cases they have built their reputations over hundreds of years,and they have become names that millions of Chinese love,respect and most of all buy.
At least once a year,Meng Wei visits several shops in Beijing that specialize in traditional goods,longing to buy something for his family in Xi'an.
"It's a routine I go through before I head home for big holidays such as the Spring Festival,"Meng says.
His shopping list includes Daoxiangcun pastries and Niulanshan Erguotou."My mother has a sweet tooth and she always has a preference for Daoxiangcun,and my uncles love the kick of Erguotou,"Meng says.
A trust in quality and a desire for things of the past are among the reasons why many people buy these time-honored brands.
However,with such brands one characteristic stands out above all else:Their popularity has endured for years,decades and in many cases centuries.That popularity was evident in the attention the public gave to them in a survey(調(diào)查) of time-honored brands in Beijing last year,which drew more than 4million respondents.
Yili,a century-old pastry brand,came out on top as the favorite.There are some old brands,too,that have been bywords for older generations,faded from view but then made spectacular comebacks.
One of these is Beibingyang (Arctic Ocean) a soft drink that was the first commercial beverage many Beijingers tasted.It disappeared from the market for 15years but resurfaced in 2010.It again proved to be a hit,many people saying it took them back to the 1960s and 1970s,and was a natural reference point as older people started recounting childhood stories to their children.
"Such brands are the product of market competition and real quality,"says Yin Jie,an official with a committee of experts charged with revitalizing Chinese time-honored brands.These brands are 230years old on average,and some were highly popular back when the country enjoyed great prosperity(繁榮) hundreds of years ago,Yin says."To this day what China contributes to these brands is certain rare natural ingredients(成分),and that keeps them going."

24.What does the underlined word"they"in Paragraph 1refer to?B
A.Big holidays.
B.Time-honored brands.
C.The respondents.
D.The older generations.
25.What does Meng Wei usually do in the Spring Festivals?B
A.He runs several shops selling traditional goods.
B.He shops traditional brands for his family.
C.He misses the things of the past very much.
D.He buys various sweeties and drinks.
26.What can be learned about the time-honored brands?C
A.They are not trusted in quality and competition.
B.Many disappeared and never made comebacks.
C.They enjoy a long time of popularity.
D.They are the childhood stories of the aged.
27.What does Yin Jie think important in keeping time-honored brands going?C
A.China's prosperity.
B.Historic influence.
C.Certain rare natural ingredients.
D.Bywords for older generations.

2.Like many Czechs (捷克人),Luká? Bern?,38,enjoys going out to the pub with his friends for conversation and a few beers."I don't drink every day,"he says."I think about three times a week.When I go out,I usually have five to six beers at a time,about the same as my friends."The beers are half-liters,or 500 ml each.
If a half-liter of four-percent beer contains 16g of pure alcohol(酒精),Bern? and his friends are drinking 80 to 96 grams of pure alcohol on each outing.The Czech Republic's National Institute of Public Health,however,suggests that men take in fewer than 24g of pure alcohol per day; women,fewer than 16g.
Medical experts in over 40 countries around the world have agreed that drinking"too much"can cause harm.What they can't seem to agree upon is just how much is"too much."National safety levels are quite different,from a limit of 10g a day in the Netherlands to Denmark's 60g.
There are a number of reasons for this.Dr.Larry Altshuler,a medicine expert for the Cancer Treatment Centers in Tulsa,explains that while everything is based on research,"Every group,race,and gender responds to alcohol differently."
Also,researchers aren't using the same models or methods.He adds,"It can be like apples and oranges.How do you measure alcohol?Units,drinks,bottles or cans?What's the alcohol content(含量)?Is it light or heavy?"While a half-liter of four percent beer contains 16g of pure alcohol,a half-liter of five percent lager contains 20g.
Constance Scharff,a director of Addiction Research at Cliffside Malibu Treatment Center in California,says she believes the reason"is largely cultural.""But the evidence is clear that the more you drink,the more likely you are to develop alcohol-related health problems."

27.The first paragraph is intended toC.A.describe the habit of Luká? Bern?
B.a(chǎn)dvise readers to live a carefree life
C.direct readers'attention to the topic of drinking
D.support the popular belief that Czechs fancy drinking
28.The underlined word"this"in Paragraph 4refers toD.A.the alcohol limit for Czechs
B.the measurement of alcohol content
C.the concern over the harmful effects of drinking
D.the difference in national safety levels of alcohol
29.According to the passage,what might determine the national safety standards of alcohol?CA.Drinking length and alcohol containers.
B.Drinking atmosphere and alcohol quality.
C.Cultural differences and measuring methods.
D.Research results and alcohol-related health problems.
30.What may be the best title for the passage?BA.How Can Drinking Be Safe?
B.How Much Alcohol Is Too Much?
C.Why Does Alcohol Do Harm to Health?
D.What Harm Will Alcohol Cause to Us?
