6．Rising levels of carbon dioxide in the atmosphere are a major cause of climate change，and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life．
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades．
"We've been going to the same spot in the Pacific Ocean，and we try and characterize long-term change in the open ocean environment．And one of the key things that we measure is CO2 levels．And we've been able to record this increasing quantity of atmospheric CO2 into the ocean．"
Scientists expected that as atmospheric CO2 increased，more and more of the carbon dioxide would be absorbed into the ocean，affecting the chemical balance of the sea water，with a potentially harmful impact on shellfish and coral in particular．
"As carbon dioxide dissolves in the water，or seawater in this case，it forms a weak acid（酸），carbonic acid，"Dore explains．"And therefore，as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater，it drives the pH down，and makes it more acidic．"
The seawater Dore and his colleagues have analyzed confirms what the theory predicts．
The effect was particular striking at about 250meters down，and again at 500meters．Dore and his colleagues came up with two possible explanations．It could be that surface water picked up CO2and then moved to those depths．Or there could be a biological explanation．
"It's important to realize that the oceans are really becoming acidic．And it can have negative impacts on a whole variety of sea life from fish to coral．It's potentially catastrophic．"

72．What can be the best title of the passage？A
A．Sea Life Facing Danger         B．Climate Change Affecting Seawater
C．Oceans Becoming More Acidic    D．Scientist Researching Seawater

a．Sea life is endangered．
b．CO2 goes into the surface water．
c．The ocean chemistry is affected．
d．CO2 decreases the PH and makes the seawater more acidic．
e．CO2 levels in the atmosphere go up．
A．a(chǎn)→b→c→d→e  B．e→b→c→d→a  C．a(chǎn)→e→c→d→b  D．e→d→c→b→a
74．Scientist Robert Dore came to the conclusion based onA．
A．his research and analysis
B．the expectation of other scientists
C．some former theory
D．a(chǎn) major cause of climate change

11．When I was growing up in America，I was ashamed of my mother's Chinese English．Because of her English，she was often treated unfairly．People in department stores，at banks，and at restaurants did not take her seriously，did not give her good service，pretended not to understand her，or even acted as if they did not hear her．
My mother has realized the limitations of her English as well．When I was fifteen，she used to have me call people on phone to pretend I was her．I was forced to ask for information or even to yell at people who had been rude to her．One time I had to call her stockbroker （股票經(jīng)紀(jì)人）．I said in an adolescent voice that was not very convincing，"This is Mrs．Tan…"And my mother was standing beside me，whispering loudly，"Why he don't send me check already two weeks ago？"And then，in perfect English I said，"I'm getting rather concerned．You agreed to send the check two weeks ago，but it hasn't arrived．"
Then she talked more loudly，"What he want？I come to New York tell him front of his boss．"And so I turned to the stockbroker again，"I can't tolerate any more excuse．If I don't receive the check immediately，I am going to have to speak to your manager when I am in New York next week．"

When I was a teenager，my mother's broken English embarrassed me．But now，I see it differently．To me，my mother's English is perfectly clear，perfectly natural．It is my mother tongue．Her language，as I hear it，is vivid，direct，and full of observation and wisdom．It was the language that helped me shape the way I saw things，expressed ideas，and made sense of the world．
25．Why was the author's mother poorly served？D
A．She was not very polite．
B．She was often misunderstood．

14．Promotion at work can be good for the pocket．However，it can also be very risky for a person's mental health，according to British researchers from the University of Warwick in Coventry．
The new findings go strongly against the common belief that advancement in a career can result in better health because of an increased sense of self-confidence，life control and overall well-being（幸福感）．"Getting a promotion at work is not as great as many people may think．Our research finds that the mental health of managers typically deteriorates after a job promotion and goes beyond merely a short-term change in a way，"said Chris Boyce，the researcher of the University of Warwick．He also added that they could not find any health benefits in individuals who had had job promotions．Instead，these people don't go to hospital to have health checks as often as they should，which may be something to worry about rather than celebrate．
To find out whether there is a connection between job advancement and physical health，Boyce and his team used data from the British Household Panel Survey．The data contained information on nearly 1，000 recently promoted individuals in the United Kingdom．And the data contained information on many aspects of life，including work and self-reported health．After analyzing all the available information，they discovered that there was no evidence of improved physical health after a job promotion．
However，what the researchers did find was evidence of greater mental stress．The experts found that promotion gives people，on average，10 percent more mental stress and up to 20 percent less time to visit their doctors in the event of illness．Matt Smith，a Scottish health expert，said mental stress is caused by working long hours．He said，"When someone is promoted there might be even more pressure to work longer hours and therefore they can't afford the time to care about their health．"
63．According to the text we can learn that work promotionD．
A．is traditionally believed to be harmful to people's health
B．decreases people's self-confidence and happiness
C．gives people more chances to have health checks
D．can help raise people's income to some extent
64．The underlined word"deteriorates"in the second paragraph means"becomesD"．
A．satisfying     B．doubtful      C．optimistic    D．worse
65．What do we know from Boyce's research？A
A．It analyzed many aspects of the promoted individuals'lives．
B．It surveyed 1，000 people in the world．
C．It showed how people gained work promotion．
D．It proved that work promotion may lead to a short-term change in health．
66．From the last paragragh we can learn thatA．
A．people who are promoted suffer from increased mental stress
B．the work after promotion will take up 20 percent of people's leisure time
C．promoted individuals tend to pay more attention to their health
D．poor health condition makes promoted individuals feel stressed
67．What is the best title for this text？B
A．Work Promotion Helps Increase Self-Confidence
B．Work Promotion Is Actually Bad for One's Health
C．Work Promotion Means Having to Work Harder
D．Work Promotion Brings Wealth and Health．

1．Researchers in Britain are driving the environmental movement to a new level．A team from the University of Warwick has built what it calls the world's first completely environmentally friendly Formula Three racing car．
The car is made mainly of renewable materials，like plants and vegetables．The structure around the car is made from natural plant fibers and potatoes．The steering wheel（方向盤(pán)） is made from root vegetables like carrots．The engine uses bio-fuel made from vegetable oil and waste chocolate．
The new racing car is extremely fast．The car has a top speed of two hundred fifteen kilometers an hour．And it can go from zero to ninety-five kilometers an hour in just two and a half seconds．
The racing car meets all of the Formula Three racing requirements except for its biodiesel（生物柴油）engine．
Automobile racing is one of the most widely watched sports in the world．But it is also considered one of the least friendly sports to the environment．Racing cars burn a lot of fuel，and create a lot of air pollution．In recent years，the racing industry has taken steps to protect the environment．More racing companies are now producing cars that use less energy．These cars produce less pollution than cars that depend on traditional fuel，like gasoline．
Last month，the new racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch．It would have been the first biodiesel-powered car to race at Formula Three．Current Formula Three rules let only gasoline-powered car to compete．Officials needed permission from all of the Formula Three racers for the biodiesel-powered car to compete．They were unable to contact one of the drivers，so the new racing car didn't appear in the event．In test runs，the new racing car was the fifth fastest among the Formula Three race cars．Supporters are hoping to have the fuel problem solved in time to compete in the next season．

66．What's the second paragraph mainly about？A
A．What materials the new racing car is made of．
B．Why researchers built the new racing car．
C．The characteristics of the new racing car．
D．The process of the new racing car being designed．
67．According to the passage，theD of the new racing car doesn't meet the Formula Three racing requirements．
A．speed      B．a(chǎn)ppearance      C．weight      D．engine
68．It can be inferred from the passage thatC．
A．the new racing car is the first environmentally friendly car
B．a(chǎn)utomobile racing could be forbidden in the near future
C．many people like to watch automobile racing
D．the new racing car will be allowed to compete in the next season of Formula Three racing
69．In recent years，racing companies are producing cars thatC．
A．burn more fuel                    B．go more quickly
C．produce less pollution            D．cost less money
70．Why didn't the new racing car compete at the Formula Three Championship Final last month？B
A．Because the new racing car still needs testing．
B．Because officials needed each racer's permission but failed to contact one．
C．Because there're some technical problems to be solved．

11．What is the single largest cause of sick leave in the UK？The answer is not the common cold or flu，but back pain．Back pain affects one in three British adults，cost the country over￡5 billion every year and is obviously difficult to treat．
But now Britain's National Health Service （NHS） will be offering a new solution：acupuncture （針灸法）．
The ancient Chinese needle therapy has been around in the UK for many years，but for the first time it has been officially supported by the NHS'advisory body，the National Institute for Clinic Excellence （NICE）．
Traditionally，doctors in the UK have advised back pain sufferers to stay active，do stretching exercises and take painkillers when necessary．In more serious cases some people are given X-rays treatment or injections with therapeutic substances．
NICE，however，says there is evidence that acupuncture may be more effective than expensive X-rays or injections，to patients who have been suffering for over six weeks should be given acupuncture treatments．
As an alternative to acupuncture，patients will be able to choose either a course of spinal manipulation （脊柱推拿） or a series of special sessions．
In the UK，acupuncture is classified as a complementary （輔助的） therapy，which is the term given to a medical procedure which hasn't been subjected to the strict trials by which scientists prove some treatment work．
While many experts have welcomed the move to make acupuncture available on the NHS，some are still skeptical about its effectiveness．
Research from the US earlier this month found that simulated acupuncture using toothpicks which do not pierce the skin could be as good as using real needles．
So while some are yet to be convinced，back pain sufferers will be hoping that acupuncture helps them feel healthy and mobile again．Employers，on the other hand，will be hoping it gets them back to work．
64．What can be the best title for the passage？A
A．Acupuncture m the UK
B．The largest cause of sick leave．
C．The ancient Chinese medicine
D．Different ways to treat back pain．
65．According to NICE，which of the following ways is more effective to treat back pain？B
A．To take painkillers                                                 
B．To use the Chinese needle therapy
C．To take X-ray treatment or injections
D．To stay active and do stretching exercises
66．Which of the following statements about acupuncture is TRUE？C
A．Doctors can use needles or toothpicks to perform acupuncture．
B．Patients taking acupuncture have to take a course of spinal manipulation．
C．Patients suffering back pain for a long time are more advised to use acupuncture．
D．Acupuncture costs less money and has lower effects than X-rays or injections
67．Why is acupuncture classified as a complementary therapy in the UK？D
A．It is not strict in the treatment
B．Some British don't have trust in it
C．The main British treatment is very effective
D．Its medical procedure hasn't been strictly tested scientifically．

I just got quite confused again，since when have Chinese begun celebrating Christmas Day？What do these people celebrate it for，the birth of Chris？But we all know that most of Chinese are not Christians，they don't even know the origin of Christmas Day，and they celebrate it for no reason．
I don't celebrate Christmas Day or any other western holidays since I'm not a Christian and nor am I a westerner．I don't know what Christmas really means．Anyway I can't get reasonable answers from my friends．Some of them think they would like to just take this chance to enjoy themselves regardless of the meaning of the festival．Some of them think I'm an old-fashioned girl，a bigot who doesn't appreciate the spirit of Chinese cultural tolerance（寬容） and understanding of other cultures．Well，if it is about cultural tolerance，why don't we ever celebrate the month of Muharram，or festivals of colours in India，or Fiestas Patrias in Mexico？
I really appreciate cultural exchanges and communications with all nations，but I don't think this is what it's about．People are celebrating more and more western festivals while ignoring our traditional ones．
Is it part of globalization（全球化）？Do people in other non-western countries also celebrate Christmas？

24．It can be inferred from the passage that the writerD．
A．is an old-fashioned girl
B．doesn't like festivals at all
C．prefers western festivals to Chinese festivals

A．for no reason
B．for the birth of Chris
C．because most of them are Christians
D．because they don't like Chinese festivals

B．a(chǎn) very stubborn person
C．a(chǎn) very careful person
D．a(chǎn) very popular person
27．We can learn from the passage thatA．
A．more and more Chinese people celebrate western festivals now
B．Chinese people pay enough attention to our own festivals
C．no Christmas celebration means one lacks cultural tolerance
D．the writer doesn't like cultural exchanges and communications with other countries．
