8.A team led by a nurseryman (花圃工人) and his sons has raced against time for 20years,using branches from some of the world's biggest and most long-lasting trees to produce clones that could restore ancient forests and help fight climate change.
Now comes the most ambitious step of the project:getting the new trees into the ground.Plantings of two dozen clones from California's huge coastal redwoods will take place Monday in seven nations:Australia,New Zealand,Great Britain,Ireland,Canada,Germany and the U.S.
The lab-produced trees are genetic copies of three huge trees that were cut down in northern California more than a century ago.Remarkably,new branches still grow from the stumps (树桩),including one known as the Fieldbrook Stump,which measures 35feet in diameter (直径).It's believed to be about 4,000years old.
"We need to reforest the planet.To do that,it just makes sense to use the largest,oldest trees that ever lived,"said David Milarch,co-founder of the non-profit Archangel Ancient Tree Archive.
Milarch and his sons Jared and Jake,who have a family-owned nursery,became concerned about the condition of the world's forests in the 1990s.They began traveling across the U.S.in search of"champion"trees that have lived hundreds or even thousands of years,believing that better genes make it possible for them to outlive others of their species.Scientific opinion varies on whether that's true,with skeptics saying the survivors may simply have been lucky.
The Archangel team says they've developed several methods of producing genetic copies.They focus on towering sequoias (高耸的水杉)and redwoods,considering them best suited to absorb great amounts of carbon dioxide (CO2),the greenhouse gas primarily responsible for climate change.
The challenge is to find places to put the trees,people to look after them and money to continue the project,Jared Milarch said.The group is funded through donations and doesn't charge for its clones.
"A lot of trees will be planted by a lot of groups on Arbor Day,but 90percent of them will die,"David Milarch said."You can't plant trees and walk away and expect them to take care of themselves."Those receiving Archangel redwoods have promised to care for them properly.

28.According to the text,the clonesC.
A.are rather expensive
B.are based on dead ancient trees
C.have been experimented for 20years
D.have been widely grown across the U.S.
29.To reforest the planet,David Milarch chooses the largest,oldest trees becauseB.
A.they are lucky treesB.they have better genes
C.they are easier to plantD.they look more beautiful.
30.David Milarch's team believes that genetic copies from sequoias and redwoodsA.
A.can take in more greenhouse gases
B.are hard to survive for a long time
C.are likely to cause climate change
D.may be a threat to existing plants
31.What is stressed by David Milarch in the last paragraph?C
A.The need of financial support.
B.The difficulty of finding places.
C.The importance of caring for trees.
D.The challenge of running his group.

2.Everyone seems to be living for someone else.
I had once helped a friend run a watermelon stall.I noticed something interesting:almost every buyer would lift the melon up to their ear,and tap it,apparently trying to listen to something.I wondered what they expected to hear.Finally I could no longer hold back my curiosity and asked a customer-an elderly gentleman-about this.Hearing my question,he roared with laughter.Then he replied in a self-mocking (自嘲) tone,"Young lady,I have been doing this for more than fifty years.But all I know is that everybody would stare at you as if you were a fool if you just pick up a melon and leave!"
Not long after that,my watermelon stall friend sent me an invitation to her wedding,which really surprised me.I asked her,"Why are you seized by a sudden desire to get married?I don't remember ever hearing you mention that you've got a boyfriend."She answered while counting money,"Everyone has to get married anyway,so it is better to get married sooner than later."
I could think of no word to refute (反驳) her.It seems that everybody is living for everybody else and has forgotten the need of their own heart.It may be safe and save a lot of worries by following others'suit in doing things.The use of WE or US will give one a steady and sure sense of pride.But why do people usually feel uneasy when using"I"?.
I find all these things somewhat funny.We have got used to following others'example.We feel at ease and justified simply because this is a way of US,a way which has been practiced by so many people.But is this massive practice really right?

25.Why did the elderly gentleman tap the watermelon before buying it?C
A.Because he expected to hear something.
B.Because he was a fool.
C.Because he just wanted to follow the crowd.
D.Because it was his habit and it was hard for him to give it up.
26.Which word can replace the underlined word"justified"in the last paragraph?A
A.reasonable B.embarrassed C.excited D.disappointed
27.Which of the following is NOT mentioned in the passage?B
A.It may be safe to do what most people do.
B.People should live for others and forget their own heart.
C.The writer felt unexpected when her friend wanted to get married.
D.The use of We or I will give speakers themselves quite different senses.
28.In which section of a magazine can you read the passage?D
A.Nature and Art
B.Sport and Health
C.Science and Technology
D.Culture and Society.
16.There are many older people in the world and there will be many more.A little-known fact is that over 60 percent of the older people live in developing countries.Accor ding to the World Health Organization,by 2020 there will be 1 billion,with over 700 million living in developing countries.
 It is a surprising fact that th e population aging is particularly rapid in developing countries.For example,it took France 115 years for the rate of older people to double from 7 percent to 14 percent.It is estimated to take China a mere 27 years to achieve this same increase.
 What are the implications of these increased numbers of older folk?One of the biggest worries for governments is that the longer people live,the more likelihood there is for diseases and for disability.Attention is being paid to the need to keep people as healthy as possible,including during old age,to lessen the financial burden on the state.
 Another significant problem is the need for the younger generations to understand and value the older people in their society.In some African countries,certainly in Asia,older people are respected and regarded as the ones with special knowledge.Yet traditions are fading away daily,which does not make sure the continued high regard of older people.As society changes,attitudes will change.
 Much needs to be done to get rid of age discrimination in employment.Life-long learning programs need to be provided to enable older people to be active members in a country's development.
 Social security policies need to be established to provide adequate income protection for older people.Both public and private schemes are vital in order to build a suitable safety net.
5.The rate of older peopleC.
A.is bigger in developed countries than in developing countries
B.is one-seventh of the population in developing countries
C.will increase much faster in China than in France
D.will be sixty percent in developing countries by 2020
6.According to passage,which of the following are governments most worried about?
A
A.The diseases and disability of older people.B.The longer life and good health of people.
C.The loss of taxes on older people.D.The increasing  respect for older people.
7.Which of the following measure is NOT mentioned to solve the population ageing problem?D
A.Getting rid of age discrimination in employment.
B.Supplying life-long learning programs to older people.
C.Making sure adequate income protection for older people.
D.Providing free health care for sick older people.
8.The author concludes in the last paragraph thatB.
A.governments have spent lots of time in solving the aging problem
B.population aging is a hard problem,but it needs to be solved urgently
C.people are too busy to solve the population aging problem
D.much time and effort will be lost in solving the aging problem.
3.My father left me a legacy (遗产) of his handwriting through letters and a notebook.In the last two years of his life,when he was sick,he filled a notebook with his thoughts about me.
After he died,I realized that no one writes to me anymore.Handwriting is a disappearing art.I'm all for email and thinking while typing,but why give up old habits for new?Why can't we have letter writing and email exchange in our lives?There are times when I want to trade all those years that I was too busy to sit with my dad and chat with him and trade all those years for one hug.But too late.But that's when I take out his letters and I read them,and the paper that touched his hand is in mine,and I feel connected to him.
As I saw my father's body being swallowed by fire,I sat by his funeral fire and wrote."I hear you and I know that you would want me to be strong,but right now,I am being sucked down,surrounded and bottled up by these forceful emotional waters,trying to purify (净化) my soul one more time,to k eep on fighting just as you taught me."
We all need to leave our children with a value legacy,a value for things with a personal touch-a book,a soul-searching letter,and not a financial one.I have no idea how I'm going to do it,but I am committed to compose my father's thoughts and mine into a book,and leave that published book for my son.
21.What are the father's letters about?D
A.Conclusions of his business.
B.Experiences of his life.
C.Views about the world.
D.Suggestions for the author.
22.How does the author connect to his father now?A
A.By reading his letters.
B.By recalling his busy years.
C.By talking all by himself.
D.By writing him letters.
23.The underlined phrase"bottled up"may probably means"B".
A.entirely removed                
B.well controlled                 
C.totally lost                     
D.wholly damaged          
24.How does the author sound when telling the story?B
A.Thoughtful  
B.Grateful.
C.Sorrowful.
D.Regretful..
13.There is something very wrong with the system of values in a society that has only unkind terms (措辞) like nerds and geeks for the intellectually curious and academically serious people.
We all know what a nerd is:someone who wears thick glasses and ugly clothes; someone who knows all the answers to the chemistry or math homework but can never get a date on a Saturday night.And a geek,according to Webster's New Word Dictionary,is a street performer who shocks the public by biting off heads of live chickens.It is an obvious fact about our language and our culture that someone who is devoted to pursuit (追求) of knowledge is compared to such a strange person.
Even at a famous educational institution like Harvard,anti-intellectualism (反智主义) is widespread:Many students are ashamed to admit,even to their friends,how much they study.The same thing happens in U.S.primary and high schools.
Enough is enough.The anti-intellectual values that have spread throughout American society must be fought.There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the US.In the most industrialized nations,especially in East Asia,a kid who studies hard is praised.But in America,average professional ballplayers are much more respected and better paid than professors of the best universities.
How can a country where typical parents are ashamed of their children studying mathematics instead of going dancing be expected to compete in the technology race with Japan?How long can America remain a world-class power if we constantly put social skills and physical strength over academic achievement and intellectual ability?
Do we really expect to stay afloat largely by bringing in our scientists and intellectuals from abroad,as we have done for a major part of this country without making an effort to also develop a pro-intellectual (有利于知识分子的) culture at home?
Not until the words"nerd"and"geek"become terms of praise rather than insults 
(侮辱) do we have a promising future.
21.What is the meaning of the words"nerd"and"geek"in this passage?B
A.They are used in the U.S.to describe students from other countries.
B.They are insulting terms which are used to describe smart students.
C.A nerd is a good student and a geek is a poor student.
D.Nerds and geeks are proper descriptions of strange students.
22.What can be learnt from Paragraph 3 and Paragraph 4?C
A.The US government doesn't mean to spend much money on education.
B.Few students work hard for their grade in famous universities like Harvard.
C.Anti-intellectualism is not popular in industrialized countries in East Asia.
D.Professors earn more than professional basketball players on average in the US.
23.What is probably the author's attitude towards the present society's anti-intellectualism?C
A.Proud           
B.Supportive        
C.Unconcerned      
D.Anxious 
24.What can be a suitable title for the text?D
A.What is anti-intellectualism?
B.Why does society avoid nerds?
C.Don't laugh at nerds.
D.America needs its nerds.
17.It would have been a success story if Fullerton High School senior Fernando Rojas,the son of Mexican immigrants whose schooling stopped in the eighth grade,was accepted to college.But the 17-vear-o1d achieved a surprising clean sweep-he was accepted to every Ivy League (常春藤)schoo1.
"I am so lucky,"Roias told The Orange County Register on Saturday."When I got all  eight,it was a blessing and a curse because I had to choose.I was excited and scared and  everything at the same time."
The first call came from Yale University in February.Within weeks calls,emails and letters followed from the other seven universities.Rojas also was accepted by Stanford University and two nearby schools,the University of California,Irvine,and California State University,Fullerton.
He is one of four children of Raul Rojas,59,and wife,Mafia,56,who moved to Fullerton  from Jalisco,Mexico,in the early 1980s.
A national speech and debate champion,Rojas reasoned that if he applied to the eight Ivy  League schools,he might get into one.Sal Tinajero,Rojas'speech and debate coach at  Fullerton,told the newspaper that Rojas is a hardworking self-starter who thrives(茁壮成长)  on competition."His biggest motivation for speech and debate was his parents to know that  their hard work meant something,"Tinajero said.
After visiting several campuses,he settled on Yale,which costs 64,000ayearwithroomandboard.Heisresponsiblefor6,000;Yale scholarships and federal grant money cover the  rest.
He'll mostly take it easy during the summer before heading to Yale in late August.He's considering majoring in Latin American studies and perhaps a career as a lawyer or in  international affairs.
24.What do we know about Fernando Rojas from Paragraph l?D
A.His schooling stopped in the eighth grade.
B.He often did some cleaning in the schoo1.
C.People were confident that he would be successful.
D.His admission to famous universities was completely unexpected.
25.How many universities accepted Rojas altogether?A
A.11.    
B.10.    
C.9.
D.8.
26.How do we understand what Tinajero said?B
A.Rojas is good at speech and debate competition.
B.The hard work of his parents inspired Rojas greatly.
C.Rojas's parents knew Rojas loved them deeply.
D.Rojas's motivation was misundestood by his parents.
27.Why did Rojas choose Yale at last?C
A.Yale is famous for Latin American studies.
B.He wants to be a lawyer as his career.
C.He cares more about the expense.
D.Yale is responsible for all his cost.
