    7．British MPs （国会议员） have voted in favour of the creation of babies with DNA from two women and one man，in a historic move．The UK is now set to become the first country to introduce laws to allow the creation of babies from three people．In a free vote in the Commons，382MPs were in favour and 128against the technique that stops genetic diseases being passed from mother to child．During the debate，ministers said the technique was"light at the end of a dark tunnel"for families．
    A further vote is required in the House of Lords．If everything goes ahead then the first such baby could be born next year．Supporters said it was"good news for progressive medicine"but critics say they will continue to fight against the technique that they say raises too many ethical （伦理的） and safety concerns．Estimates suggest 150three-person babies could be born each year．
    Prime Minister David Cameron said："We're not playing god here； we're just making sure that two parents who want a healthy baby can have one．"The method，which was developed in Newcastle，should help women like Sharon Bernadi，from Sunderland，who lost all seven of her children to mitochondrial （线粒体的） disease．Ms Bernadi said she was"overwhelmed"by the decision．
    Mitochondria are the tiny compartments （隔间） inside nearly every cell of the body that transform food into useable energy．They have their own DNA，which does not affect characteristics such as appearance． Defective mitochondria are passed down only from the mother．They can lead to brain damage，muscle wasting，heart failure and blindness．The technique uses a modified version to combine the DNA of the two parents with the healthy mitochondria of a donor woman．It results in babies with 0.1% of their DNA from the second woman and is a permanent change that would be passed down through the generations．

    25．According to the passage，which of the following statements is NOT true？C
    A．The new technique is intended to provide the parents a healthy baby．
    B．The mitochondrial disease can lead to various fatal illnesses．
    C．Britain is the first country to have created three-person babies．

    8．We've used the wind as an energy source for a long time．The Babylonians and Chinese were using wind power to pump water for irrigating crops 4，000 years ago，and sailing boats were around long before that．Wind power was used in the Middle Ages，in Europe，to grind（磨碎） corn，which is where the term"windmill"comes from．
    We can use the energy in the wind by building a tall tower，with a large propellor on the top．The wind blows the propellor round，which turns a generator to produce electricity．We tend to build many of these towers together，to make a"wind farm"and produce more electricity．The more towers，the more wind，and the larger the propellors，the more electricity we can make．It's only worth building wind farms in places that have strong，steady winds，although boats and caravans（大篷车）increasingly have small wind generators to help keep their batteries charged．
    The best places for wind farms are in coastal areas，at the tops of rounded hills，open plains and gaps in mountains-places where the wind is strong and reliable．Some are offshore．To be worthwhile，you need an average wind speed of around 25 km/h．Most wind farms in the UK are in Cornwall or Wales．Isolated places such as farms may have their own wind generators．In California，several"wind farms"supply electricity to homes around Los Angeles．
    The propellors are large，to obtain energy from the largest possible volume of air．The blades can be angled to cope with varying wind speeds．Some designs use vertical turbines（垂直涡轮机），which don't need to be turned to face the wind．The towers are tall，to get the propellors as high as possible，up to where the wind is stronger．This means that the land beneath can still be used for farming．
    66．The first paragraph aims to introduce to usD．
    A．the function of wind power                
    B．the source of wind power
    C．the nations using wind power                        
    D．the history of using wind power
    67．How does a wind power work？D
    A．The generator turns the propeller blades and produce electricity．
    B．The tall tower helps turn the energy in the air into electricity．
    C．Warm air rises and makes the propellor move round．
    D．The propellor blown round by wind turns the generator to produce electricity．
    68．The best places for building the wind farm are places whereD．
    A．boats and caravans can often be seen         
    B．isolated farms don't have enough electricity
    C．there are less human activities                   
    D．the wind is strong and reliable
    69．We can infer from the passage thatB．
    A．wind farms will not take up too much farming land
    B．wind farms need no fuel because wind is free
    C．the blades can be angled to turn to face the wind wherever it comes from
    D．the higher and larger the towers are，the stronger the wind is
    70．What can be a suitable title for the passage？B
    A．Where to build a wind farm．
    B．ABC of the using of wind energy．
    C．How to make best use of wind．
    D．Wind energy is the best energy．

    5．Some people may be born happy，while others are genetically negative，scientists have suggested in a study published late February in a British journal．
    Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter （神经传递素） serotonin works within the brain．Serotonin，a hormone （荷尔蒙），passes chemical messages between nerve cells．It has been closely linked to mood．Several anti-depressant （抗抑郁） drugs regulate serotonin levels．
    Scientists had also identified three variants （变体） of the gene．Two so-called"short"variants were linked to a higher risk of depression and suicide （自杀） attempts．Unlike the two"short"variants，the"long"variant of 5-HTTLPR showed a clear dislike of negative images，such as fierce animals，and a clear liking for positive ones，such as flowers．
    Researchers from the University of Essex in Britain showed participants a series of images，which were divided into three kinds：negative ones aimed at inspiring fear or stress such as a snake or person about to commit suicide，pleasant ones and neutral （中性的） ones．
    The participants who had the long variant of the 5-HTTLPR gene"showed a clear dislike of negative material alongside a careful attention for positive material，"the researchers found．They paid close attention to the pretty pictures，and ignored the frightening ones．On the other hand，the short variant groups had the opposite reaction．
    In January，the Australian government organized"happiness workshops"，teaching government staff how to be happy．The department that held the"happiness workshops"said unhappy staff weren't productive staff．
    Australian political opposition parties have argued that the"happiness workshops"are probably a waste of money and couldn't increase productivity as intended．However，whether the workshop will have a happy or disappointing result，we will have to wait and see．

    71．Various kinds of images were shown to the participants toC．
    A．draw their attention
    B．cater to their different tastes
    C．find out about their reactions
    D．teach them to improve their artistic appreciation
    72．The"short"variants of 5-HTTLPR differ from the"long"variants of 5-HTTLPR in thatB．
    A．the former is connected with positive mood while the latter negative
    B．the former is connected with negative mood while the latter positive
    C．the former has a greater effect on one's mood than the latter
    D．the latter has a greater effect on one's mood than the former
    73．Which of the following statements is true about"happiness workshops"？D
    A．Most people believe that they are a waste of money．
    B．They will be beneficial in the long run．
    C．The purpose of"happiness workshops"is to teach all Australians to be happy．
    D．They are organized in the belief that happy staff can work more efficiently．
    74．It can be learned from the article thatA．
    A．drugs can be used to control people's serotonin levels
    B．happiness is more important than sadness
    C．nothing can affect our mood
    D．people with the short variant of 5-HTTLPR prefer a flower to a snake
    75．The article is mainly aboutB．
    A．the reason for the foundation of"happiness workshops"
    B．the link between people's mood and their gene
    C．the study on people's likes and dislikes
    D．the differences in people's attitude towards life．

    12．With alarming regularity，we read about oil tankers having accidents near land and the terrible consequences of the oil spills （泄露） on people，nature，and the environment．
        Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals，beaches，and land spoiled by the oil．Unfortunately，when many of these chemicals are used，more damage is caused to the environment，especially to lives in the sea．
        Of all of today's environmental disasters，an oil spill may actually be one of the least serious．Although oil is poisonous，it is a natural material．In the end，it breaks down naturally．There are，of course，long-term effects，but it is usually more serious in the short term．
        Nature by itself works better than chemical materials，but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible．In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120，000 tones of oil into the ocean．If you go there today，you will find it hard to see any sign that it ever happened．
        Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly，the biggest companies in the world produce cars，and the next biggest supply the gasoline to make them run I
        We should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies，such as cars run by solar power （太阳能），electricity，hydrogen，and so on．Much of this research has，in the past，been held back by the oil，gas，and coal．
        If the world's millions of cars were 10% more efficient （高效的）-and the industry could easily produce cars at least twice as efficient？we would need many fewer tankers crossing the oceans each year．If this happened，the risks of oil spills would be reduced，and the air we breathe would be cleaner and fresher，too．
    63．What is the passage mainly talking about？A
    A．Oil spills pollution．      
    B．What oil pollution is．
    C．Oil tanker accidents．
    D．How to reduce oil pollution．
    64．How does the author support the idea that oil spills are not as serious as people believe？C
    A．By giving a description．       
    B．By making an argument．
    C．By giving an example．     
    D．By drawing a diagram．
    65．What does the underlined word"risk"in Paragraph 5 refer to？D
    A．Transportation depending more on oil．
    B．Poisonous oil breaking down naturally．
    C．Millions of tons of oil spilling into the sea．
    D．More environmental damage being caused．
    66．Which suggestion，is made for reducing oil tank accidents according to the passage？B
    A．We should build safer tankers in the near future．
    B．We should develop new technologies to cut oil use．
    C．Tankers should not be allowed to sail near the coastlines．
    D．Countries should build more oil pipelines under the sea．

    2．I'm usually fairly doubtful about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50years ago．While any of these statements might be true，they are practically impossible to prove scientifically．Still，I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s．In fact，the analysis showed，normal children aged 9to 17exhibit a higher level of anxiety today than children who were treated for mental illness 50years ago．
    Why are America's kids so stressed？According to the report there are two main causes：increasing loneliness─brought on by high divorce rates and little communication with society，among other things─and a growing perception that the world is a more dangerous place．
    Given that we can't turn the clock back，adults can still do plenty to help the next generation handle such difficulties．At the top of the list is giving children a better appreciation of the limits of individualism （个人主义）．No child is an island．Strengthening social ties helps protect individuals against stress．To help kids build stronger connections with others，you can pull the plug on TVs and computers．Your family will thank you later．They will have more time for face-to-face relationships，and they will get more sleep．
    Limit the amount of virtual  violence your children are exposed to．It's not just video games and movies； children see a lot of murder and crime on the local news．Keep your expectations for your children reasonable．Many highly successful people never attended Harvard or Yale．Make exercise part of your daily routine．It will help you deal with your own anxieties and provide a good model for your kids．Sometimes anxiety is unavoidable．But it doesn't have to ruin your life．

    125．The author thinks that the conclusions of any research comparing people's state of mind today with people's state of mind in the past areD．
    A．surprising           B．confusing      
    C．interesting          D．questionable
    126．What does the author mean when he says，"we can't turn the clock back"（Paragraph 3）？B
    A．It's impossible to slow down the pace of change．
    B．The social reality children are facing cannot be changed．
    C．Lessons learned from the past should not be forgotten．
    D．It's impossible to forget the past．
    127．According to the analysis，compared with normal children today，children treated as mentally ill 50years agoC．
    A．had little communication with friends
    B．were probably less self-centered
    C．probably suffered less from anxiety
    D．were considered less individualistic
    128．The first and most important thing parents should do to help their children isC．
    A．to provide the children with a safer environment
    B．to lower their expectations for the children
    C．to get the children more active socially
    D．to set an example for the children to follow
    129．What conclusion can be drawn from the passage？A
    A．Anxiety，though unavoidable，can be dealt with．
    B．Children's anxiety has been taken too seriously．

    9．Computerised trading agents may help humans build better markets
    THANKS to declining markets，investment banks are getting rid of many of their highly-paid traders．When markets recover，the banks might be tempted to replace them with rather cheaper talent．One alternative has been around for a while but has yet to catch on：autonomous trading agents-computers programmed to act like the human version without such annoying costs as holidays，lunch breaks or bonuses．Program trading has，of course，been done before； some blamed the 1987stock market crash on computers instructed with simple decision-making rules．But robots can be smarter than that．
    Dave Cliff，a researcher at Hewlett-Packard Laboratories in Bristol，England，has been creating trading robots for seven years．In computer simulations he lets them evolve"genetically"，and so allows them to adapt and fit models of real-world financial markets．His experiments have suggested that a redesign of some markets could lead to greater efficiency．Last year，a research group at IBM showed that Mr Cliff's artificial traders could consistently beat the human variety，in various kinds of market．Nearly all take the shape of an auction（拍卖）．One well-known type is the English auction，familiar to customers of the salesrooms（拍卖场）of Christie's and Sotheby's，where sellers keep mum on their offer price，and buyers increase their bids by stages until only one remains．
    At the other extreme is the Dutch auction，familiar to 17th-century tulip-traders in the Netherlands as well as to bidders for American Treasury bonds．Here，buyers remain silent，and a seller reduces his price until it is accepted．Most markets for shares，commodities，foreign exchange and derivatives are a mixture of these two types：buyers and sellers can announce their bid or offer prices at any time，and deals are constantly being closed，a so-called"continuous double auction"．
    Mr Cliff's novel idea was to apply his evolutionary computer programs to marketplaces themselves．Why not，he thought，try and see what types of auction would let traders converge（趋同） most quickly towards a balance price？The results were surprising．In his models，auctions that let buyers and sellers bid at any time like most of today's financial exchanges were less efficient than ones that required relatively more bids from either buyers or sellers．These"evolved auctions"also withstood big market shocks，such as crashes and panics，better than today's real-world versions．Mr Cliff's most recent results，which will be presented in Sydney，Australia，on December 10th，show that the best type of auction for any market depends crucially on even slight differences in the number of buyers and sellers．
    Bank of America has been investigating these new auctions，along with robotic traders，for possible use in electronic exchanges．The hope is that today's financial auctions and online marketplaces might work better by becoming more like their English and Dutch ancestors．

    67．What is the passage mainly about？B
    A．A review of two kinds of auctions．
    B．An introduction of trading robots．
    C．A survey of the trading market．
    D．About trading alternatives．
    68．Which of the following is true according to the text？C

    6．Like all animal species，plant species must spread their offspring to suitable areas where they can grow and pass on their parents'genes．Young animals generally spread by walking or flying．Because plants don't have that ability，they must somehow hitchhike（搭车）．Some plant seeds scatter by blowing in the wind or floating on water．Many other plant species，though，trick an animal into carrying their seeds．How do they do this？They enclose the seeds within a tasty fruit and advertise the fruit's ripeness by its colour or smell．The hungry animal collects and swallows the fruit，walks or flies off，and later spits out the seeds somewhere far from its parent tree．Seeds can thereby be carried for thousands of miles．It may surprise you to learn that plant seeds can resist digestion．In fact，some seeds actually require passage through an animal's body before they can grow．
    Wild strawberries offer a good example of hitchhiking tactics．When strawberry seeds are still young and not yet ready to be planted，the surrounding fruit is green，sour and hard．When the seeds finally mature，the berries turn red，sweet，and tender．The change in the berries'colour serves as a signal to birds which then eat the strawberries，fly off，and eventually spit out the seeds．
    Naturally，strawberry plants didn't set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed．Nor did birds set out with the intent of planting strawberries．Rather，strawberry plants evolved through natural selection．The sweeter and redder the final strawberry，the more birds spread its ripe seeds； the greener and more sour the young strawberry，the fewer birds destroyed the seeds by eating berries before the seeds were ready．
    46．What does the underlined word"dispersed"in the third paragraph mean？A
    A．spread                                
    B．eaten         
    C．born                                  
    D．planted
    47．For plants，which of the following is NOT a way of spreading their offspring to suitable areas？D
    A．Hitchhiking．
    B．Blowing in the wind．
    C．Floating on water．
    D．Tracking an animal．
    48．Which strategy does the example of wild strawberries describe？D
    A．The conscious intent of attracting birds．
    B．Spreading by walking．
    C．Spreading by flying．
    D．The strategy of taking a lift．
    49．Why does the author describe how strawberry seeds are spread？C
    A．To show plants are good at adapting to the environment．．
    B．To show strawberry's special way．
    C．To show the plant has different ways of spreading seeds．
    D．To show the mystery of plant．
    50．What's the passage mainly about？B
    A．How animals disperse offspring．
    B．How plants disperse their offspring．
    C．Plant evolution．
    D．Plants'hitchhiking on animals．
