Plastic is one of the most important technological discoveries of the 20th century．How    ever．it may soon be replaced．The new development――liquid wood――can replace plastics    in a11 branches of modern―day industries．

Plastic as a material enjoys the biggest demand in the modern world，but it does have a number of drawbacks．First and foremost，plastic isn’t recyclable．Secondly，it contains toxins(毒物)helping develop cancerous diseases．Finally，it's made of oil and oil reserves aren’t endless．

The liquid wood technology is likely to replace plastic and providing mankind with new materials for many years ahead．Norbert Eisenfreich．a senior researcher at the Faunhofer Institute for Chemical Technology in Germany(ICT)，said that arboform，the new material，is made of lignin(木质素)，which can be obtained from soft tissues of wood．Once mixed with several other materials，it turns into solid and nontoxic alternative for plastics．

ICT team leader Emilia Regina Inone――Kauffmann said the wood-working industry separates wood into three basic components，including lignin．Lignin isn’t used for the production of paper．Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted(熔化)and molded(铸型)．

When solid，arboform looks like plastic and possesses the qualities of polished wood．It can be used for the production of any items．Arboform is already used for the production of car parts which require extra strength．In addition，liquid wood can be recycled repeatedly．he material preserved all of its qualities even if it’s reprocessed ten times．

However，the new invention doesn’t enjoy an extensive use due to the high content of sulphur(硫)in it．German researchers are sure to reduce the amount of sulphur by 90 percent very soon to make arboform usable for ho，me needs．

    69．Towards the founding of the Canada Prize，David Pecaut is              ．

    A．unconcerned    B．doubtful    C．hopeless D．optimistic

    68．Those participating the final round of the new Canada Prize             

    A．needn’t experience semi―final rounds

    B.  will have their performances broadcast on the TV 

    C．need to have their performances made into films

    D．must accept the judge from Canadian experts

    67．According to David Pecaut , the new Canada Prize will               

    A．be divided into four detailed parts

    B．have at least twelve winners

    C．be held every four years in Canada   

    D．offer every winner about$25 million

  66．Why did David Pecaut have the idea of founding a new Ganada Prize?

    A．To enlarge the content of the Luminato festival．

    B．To consider his own benefits from the prize．

    C．To advance Canada’s honor and opportunities．

    D．To make more Canadians get world prizes．

 65．We can conclude from the passage that                 

    A．foreign students are not permitted to do whatever jobs they like in the US

    B．IELTS is also necessary for job application like TOEIC。

    C．every graduate from colleges can get a postdoctoral position if they want to

    D．students from Iran aren’t．allowed to have jobs in America

A new Canada Prize for the Arts and Creativity could be in place by 20 1 0，with large cash prizes for emerging(新兴的)artists in dance，music，theatre and visual arts．

The prize is the idea of Tony Gagliano and David Pecaut，founders of the Luminato festival，wh0 were probably able to convince the federal government to back it．The federal budget has allocated$．25 million to support the awards open to emerging artists that have the prestige(声望)of a Nobel Prize.   

“When you think about the major prizes of the world―the Nobel Prize．in Sweden，the Kyoto prizes in Japan or the Booker Prize in the U．K．一the bring great，honor and opportunity to the countries that award them，’’ Pecaut said．“The．idea here is that every year，the Canada prizes will be awarded to the very．best promising emerging artists around the world in those four fields．”

 A jury(评委会)of international experts would judge the 12 finalists，who would come to  Canada and perform or show their work in public to win。the Canada prizes．The performances would be televised，allowing Canadians across the country．to see it．

The federal government liked the idea of such an international prize that would advance Canada’s brand，draw tourists and arts professionals from around the world．For the Canadian arts people．one of the greatest challenges is connecting to that international arts world to come up with CO―productions and foreign investment(投资)and touring chances．

    A group is working toward establishing the prize by 2010，with potential for semi-final

  rounds to take place：about the same time as the Vancouver Olympic Games．“Thirty or forty years from now，the future outstanding dancers and performers will look back and say。‘I broke out on the world scene in Toronto―that’s where 1 was discovered’”
