8.It was shortly before midnight,and Dr Patricia was getting ready for bed.The phone rang on the end of the line was a woman about to break a promise.
The woman was her mother's neighbour.Flora Harris had made the neighbour swear she wouldn't tell her daughter she'd a heart attack and was in the hospital,for fear her daughter would worry.The neighbour wisely decided to disobey orders.
Harris desperately wanted to get to the hospital immediately,but she couldn't.She lives in Washington,D.C,and her mother lives in California.
For the past year a half,Harris has gone to Los Angeles every other month to take care of her mother.Flora Harris takes care of her husband,James,who's 91and has Alzheimer's disease.They live in their own home,and a caregiver comes to help them a few hours a day.
Harris is one of many Americans facing the heartache of how to take care of aging parents from afar.She's often worried,not to mention extremely busy with a demanding job,two teenage daughters and the frequent trips to California.
In some ways,Harris is lucky.She has the resources to make the trips to Los Angeles.Plus,Harris is a doctor who treats the elderly.
"But it's still tough,"she said."I can foresee what the next few years are going to look like,and it's not a pretty picture.My father's going to need diapers (尿布).There will come a time when he won't recognize me and he's easily excited.I worry he's going to be violent and hurt my mother."
So what do you do when you live a continent away for your aging,sick parents?There are no magic answers.You can hire someone to help,but you can't outsource it completely.

28.Why was the woman thought to have broken a promise?D
A.She failed to take care of Flora.
B.She was not supposed to call Harris at midnight.
C.She couldn't go to hospital on time.
D.She told Harris about her mother's illness.
29.What can we learn about Patricia Harris from the passage?A
A.She thinks it harder to look after her parents the next few years.
B.He parents cannot take themselves at all.
C.She cannot do a demanding job.
D.She cannot afford to go to California often.
30.What does the underlined word"outsource"in the last paragraph mean?A
Arrange somebody outside to do a job.
B.Work something out by oneself.

7.FIVE Americans swept the three Nobel Prizes in Physics,Chemistry,Physiology (生理学) or Medicine last week.It was the first American sweep of the Nobel science prizes since 1983.
It's rare for Americans not to receive any of the science prizes,especially in recent years.In 2004,seven Americans were among the 10laureates (获奖者) for the science prizes.Last year,the figure was five out of 10.
The huge sums of money invested in scientific research is one factor that has helped many Americans to win awards.Another reason is the vast number of researchers working in the US.American universities also often have a more"creative university environment"where people can focus on research for a long period without any pressure,said Anders Liljas,member of the Nobel Committee.

New hope for AIDS patients?
AMERICAN scientists Craig Mello (top) of the University of Massachusetts Medical School and Andrew Fire (above) of Stanford University School of Medicine won the Nobel Prize for Physiology or Medicine last Monday.Their discovery is a process that researchers hope to use to silence disease-causing genes (基因).It offers new ways for disease treatment.
Scientists now hope to develop a new technique that could be used to treat diseases,such as cancers,AIDS and Parkinson's disease.

Like father,like son?
AS the son of a Nobel Prize winning professor,Roger D.Kornberg (left) had a lot to live up to.But,nearly half a century after his father,won his award,Kornberg,59,a Stanford University professor,won his own last Wednesday:The Nobel Prize in Chemistry.His research into how cells read their genes is very important.It could help lead to the development of new drugs to fight cancer (癌症),heart disease and other illnesses,experts said.
First light of the universe
TWO Americans won the Nobel Prize in Physics last Tuesday for measuring the oldest light in the heavens.It is considered as"one of the greatest discoveries of the century".It convinced (使确信) scientists that the Big Bang theory (大爆炸理论) of the universe's origin is correct.George F.Smoot (top),61,of Lawrence Berkeley National Laboratory in Berkeley,and John C.Mather (above),60,of NASA's Goddard Space Flight Centre,will share the US1.4millionprizefortheirwork.Beginningin1989,theymeasuredweaklightthatoriginated(源于)asearlyas380,000 years after the Big Bang.

6.It was a rainy morning two years ago.Shirley Huxham was cycling gently downhill.As she waved to a friend,her bike slid uncontrollably on the wet road,throwing her to the ground."I'd never even thought of buying a helmet,"she says.For months she was partly paralysed(瘫痪的) down her left side and still has health problems today.
Some might think that Shirley was just unlucky.How dangerous can it be to fall from a bicycle?In fact,each year on Britain's roads more than 200people are killed and at least 4,000seriously injured on bicycles.But these numbers don't tell the whole story:the majority of the dead and injured were not wearing helmets.
A study of bicycle accidents in the US found that helmets could reduce the risk of serious head injury by 85percent.Yet it is estimated that in Britain,no more than five percent of bicycle-riders wear helmets.Why don't more cyclists wear them?
People think that helmets look foolish,that they're inconvenient,and that accidents only happen to other people.
One of the wrong ideas bicyclists have is that lower speeds can put them at less risk than motorcyclists,who are legally obliged to wear helmets.In fact,according to a British report,a higher percentage of bicyclists than motorcyclists suffer head injuries.And their injuries can be just as severe.
Helmets,however,can make a big difference.Shirley wasn't just unlucky.If she had worn a helmet,she wouldn't have spent months in hospital.Why take the risk?

38.The reason why Shirley got badly injured was thatC.
A.She was riding her bicycle downhill too fast.
B.Her friend's waving to her made her lose control.
C.She ignored the importance of wearing a helmet.
D.The ground was barely wet.
39.Which of the following statements is right according to the passageD?
A.Wearing helmets will reduce the risk of being killed by 85%.
B.Nearly 5percent of bicycle-riders wear no helmet in UK.
C.Motorcyclists suffer more head injuries than bicyclists.
D.In UK a motorcyclist's wearing no helmet is against the law.
40.People don't like wearing helmets due to the following reasons exceptD.
A.Wearing helmets makes them look silly.
B.They don't think wearing a helmet is convenient.
C.Falling off a bicycle only happens to other people.
D.Wearing a helmet is not fashionable at all.

4.Can people change their skin color without suffering like pop king Michael Jackson?Perhaps yes.Scientists have found the gene that determines skin color.
The gene comes in two versions,one of which is found in 99percent of Europeans.The other is found in 93to 100percent of Africans,researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebra-fish(斑马鱼) to uniform gold by inserting a version of the pigment (色素) gene into a young fish.As with humans,zebra-fish skin color is determined by pigment cells,which contain melanin (黑色素).The number,size and darkness of melanin per pigment cell determine skin color.
It appears that,like the golden zebra-fish,light-skinned Europeans also have a mutation (变异) in the gene for melanin production.This results in less pigmented skin.
However,Keith Cheng,leader of the research team,points out that the mutation is different in human and zebra-fish genes.
Humans acquired dark skin in Africa about 1.5million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线),which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes,they need more sunlight on their skin to produce vitamin D.So the related gene changes,according to Cheng.
Asians have the same version of the gene as Africans,so they probably acquired their light skin through the action of some other gene that affects skin color,said Cheng.
The new discovery could lead to medical treatments for skin cancer.It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.

57.It can be inferred from the passage thatC.
A.the new discovery couldn't help to find medical treatments for skin cancer.
B.Europeans and Africans have the same gene.
C.nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment.
D.there are two kinds of genes.
58.Scientists have done an experiment on a dark-striped zebra-fish in order toA.
A.prove the humans'skin color is determined by the pigment gene.
B.find the different genes of humans'.
C.find out the reason why the Africans'skin color is dark.
D.find out the ways of changing people's skin color.
59.The reason why Europeans are light-skinned is probably thatB.
A.they are born light-skinned people.
B.light-skinned Europeans have mutation in the gene for melanin production.
C.they have fewer activities outside.
D.they pay much attention to protecting their skin.
60.The passage mainly tells us thatD.
A.people can not change their skin color without any pain.
B.the new discovery could lead to research into ways to change skin color safely.
C.pop king Michael Jackson often changed his skin color as he liked.
D.scientists have found out that people's skin color is determined by the gene.

3.Good relationships are definitely good sources of happiness in life.We all want happy relationships but if we do not keep that relationship alive,it can also be one of the most  distraughtthings in life.There may be no hard and fast rules in making good relationships,as each of us has different preferences and points of view as to what is a great relationship.The following are some major key points in making relationships work.
It is often said that building good relationships is all about communication.Good communication indeed governs a good relationship-knowing the right thing to say,when to say it,how to say it,and accepting that some things are better left unsaid.I personally think communication must be broadened because relationships involve more decisions to make.From study to work,from money to entertainment and even in things about yourself or about your friend that you do not know,communication is essential in these aspects of the relationships.
Of course,being with someone is not saying that you totally agree with him all the time.You and your friend come from different family backgrounds,raised in different environments so there may be disagreements here and there.However,it is important in making relationships work to express disagreements without pushing the relationship to end.Again,good communication and learning to compromise (妥协) at times are necessary.
As the relationship lasts longer,you may also discover things about you and your friend that you may not have known before.Therefore,supporting each other on both your"hidden selves"can also make a good relationship.
Love is an important aspect of building relationships and for me,I always believe that love needs open communication,respect,support and understanding each other in making relationships work.

53.The underlined word"distraught"in Paragraph 1probably meansD.
A.helpless      
B.surprising         
C.funny         
D.upsetting
54.To communicate well with people,you should know thatC.
A.supporting each other in anything helps build a good relationship
B.compromises are essential at any time
C.a white lie is necessary sometimes
D.your friends need to have the same backgrounds with you
55.According to the text,which of the following are important for a good relationshipD?
a.communication       b.support      c.love        d.hidden selves
A.a,b,d            
B.a,c,d            
C.b,c,d         
D.a,b,c
56.What would be the best title for the textB?
A.The Importance to Express Disagreements
B.Keys to Making Relationships Work
C.Different Opinions on Good Relationships
D.Forbidden Rules in Building Good Relationships.

2.The World Health Organization reports a number of people have died of the Ebola virus in central Africa during the last few months.Ebola,also known as Ebola hemorrhagic (出血) fever or Ebola viral disease.is a rare and deadly illness with high death rates in humans and primates.The natural source of Ebola virus remains unknown,although bats seem to be the most likely source.
The Ebola virus began spreading after victims were discovered in northeastern Cabon.So far,it is the third time Ebola has spread through Cabon since 1994.Health officials believe people moving across the border spread the disease from Cabon co Congo Ebola is highly infectious and kills up to 80% of its victims.Researchers do not know the method with which the virus first appears in humans,but they believe it is through infected animals.The disease then spreads from person to person through blood and other body liquids.
Ebola victims treated early have the base chance of survival.Signs of Ebola include a high temperature,diarrhea,muscle pains and bleeding inside the body.in severe cases,victims experience chest pains and death.There is no known cure for the disease and no way yet to prevent it.
Scientists at the American National institutes of Health are working to develop a vaccine(疫苗) to prevent Ebola.Doctor Cary Nobel is leading the research effort at N-l-H testing center in the eastern state of Maryland.He says that during the past two years,the vaccine has been tested on small animals and monkey a for safety and effectiveness.
In the most recent study,four monkeys who had been given the vaccine were completely protected from a deadly injection of the Ebola virus.the study was described in November in Nature magazine.Doctor Nobel says the tests appear to have moved scientists one step closer to a vaccine for humans.
28.Where does the Ebola virus come fromD?
A.Bats.B.Monkeys.C.Infected humans.D.Something unknown.
29.When infected with Ebola virus,people may experience the following exceptA.
A.heart attack B.a rise in temperature

4.Phrases like"tiger mom"and"helicopter parent"have made their way into everyday language.Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort,we might turn out children with bright futures.But is there anything wrong with a kind of"overparenting style"?
Parental involvement has a long history of being studied.Many of the studies,conducted by Diana Baumrind,a famous psychologist at the University of California,Berkeley,have found that a good parent is the one who is involved and reacts to her child in a positive way,who sets high expectations but gives her child independence.These"authoritative parents"appear to hit the sweet spot of parental involvement and generally raise children who do better academically,psychologically and socially than children whose parents are not strict and less involved,or controlling and more involved.Why is this parenting style so successful?
Authoritative parents actually help improve motivation in their children.Carol Dweck,a social psychologist at Stanford University,has done research that indicates why authoritative parents raise more motivated children.In a typical experiment,Dr.Dweck takes young children into a room and asks them to solve a simple puzzle.Most do so with little difficulty.But then Dr.Dweck tells some,but not all,of the kids how clever they are.As it turns out,the children who are not told they're smart are more motivated to solve increasingly difficult puzzles.They also show higher levels of confidence and show greater progress in puzzle-solving.
As the experiment suggests,praising children's talents and abilities seems to shake their confidence.Dealing with more difficult puzzles carries the risk of losing one's status as"smart".Dr.Dweck's work strongly supports that of Dr.Baumrind,who also found that reasonably supporting a child's independence and limiting interference (干涉) causes better academic and emotional results.
The central task of growing up is to develop a sense of self that is independent and confident.If you treat your young child who is just learning to walk as if she can't walk,you reduce her confidence.Allowing children to make mistakes is one of the greatest challenges of parenting.It is easier when they are young.The potential mistakes carry greater risks,and part of being a parent is reducing risk for our children.

24.According to the passage,a"tiger mom"D.
A.helps her children realize their dreams
B.speaks her children's everyday language
C.places reasonable expectations on her children
D.pays close attention to her children's experiences

A.cause more problems in children
B.foster independence in children
C.face more challenges of children
D.lead to children's academic success
26.The example of the children doing the puzzles suggests thatB.
A.a good game plays a big role in training young minds
B.overpraising makes children less motivated and confident
C.puzzle-solving can give children the motivation they need
D.bright children usually show less confidence in difficult games
27.The last paragraph tells us thatC.
A.children should not be given much freedom
B.parents should not increase the risk of challenging
C.parents should allow their children to learn from mistakes
D.children should correct mistakes with the help of their parents.

3.A.Openness to the world
B.The grace of trusting in strangers
C.Star in your own movie
D.Often change your course
E.Learn how to make decisions
F.A new best friend (or love)

Nearly everyone likes traveling.Sometimes we will travel with our friends or families,but sometimes we will travel alone.Different ways for traveling will give you different feelings.Here are five benefits you can gain by traveling alone.
(61)E
For me,traveling alone was one crash course(速成班) in making decisions--just keep on rolling the dice(骰子) and see what comes up.Stop the research.Stop the analysis paralysis.Just keep choosing and living.In travel,everything is as it is,and there's always another day to change course and choose again.A lot more happens in life when you stop worrying about what to do and just go.
(62)A
The sense of risk and reward is what draws me to traveling alone.Traveling with a friend can be an adventure too,but the adventure quotient(指数) is usually higher when you are alone.You're more vulnerable(脆弱) in the sense that you have to seek out company and help.Hey,just because I'm traveling alone doesn't mean I can't ask a hunky Carioca volleyball player to put sunscreen on the hard-to-reach places.That's the advantage of traveling alone,isn't it?Openness to adventure.
(63)B
Traveling alone also teaches you to trust your fellow men and women.They are the ones who help you out when you are in need.I will never forget the man who stopped a long-distance bus for me in Colombia so he could go buy me Coke and toilet paper (I confessed to him that I had"digestive"issues right before we got on the bus).Then he invited me to his family's home for lunch,and I still get emails from the family saying they will never forget me.
(64)C
When you travel alone,the trip is completely yours.You are the star of your own movie.All the mistakes are yours to make,the accidental discoveries to enjoy,and the insights to savor.The recollection of the trip is entirely personal and private.
(65)F
In a whole year of travel,I made a new best friend who I know will be a friend for life.We will be at each other's weddings if we get married,we coach each other through our post-(or newly)-travel lives,and we hope to meet up for other adventures in Africa,Asia,and to dance tango in Buenos Aires.Our friendship is pure gold and we have both helped each other grow in countless ways.That openness to a new friend might not have been there if I had already been traveling with someone else.And who knows?You might meet the love of your life.
