    A great effort to discover the function of every gene in the mouse genome(基因组)looks likely to provide scientists with the final mouse model of human diseases.

    The International Mouse Phenotyping Consortium(IMPC)(国际小鼠表型联盟)finds that it will take the next ten years to complete its task and it will need about $900 million. But at a meeting on mouse models of human diseases in London, where the project was carried out last week, scientists announced a commitment of $110 million from the US National Institutes of Health (NIH)in Bethesda, Maryland over the next five years.

    “The project will explain the genes—it is going to be transformative for biology” says James Battery, director of the National Institute on Deafness and Other Communication Disorders.

    The IMPC aims to take mice of the same genetic background and create viable (能自行生长发育的) strains in which one of the 20,000 or so genes in the mouse genome is knocked out. The knockout strains will then be put through strict, systematic phenotypic screens, which will check for physical and behavioral differences. The information will be stored in an open database.

    Scientists would, for example, be able to turn to the database to learn more about an unfamiliar gene signaled in a genomewide connection study in humans as being possibly related to a particular disease. Making the mutant(变异的) animal and phenotyping it in a lab could take three years.

    According to Battery, the NIH thinks that its investment in the largescale programme will actually save money in the long run, because it already spends “hundreds of millions of dollars per year” supporting small­scale grants(赠款)for scientists wanting to create their own particular gene of interest.

    Mouse “clinics” have appeared quickly around the world to screen mutant mice for heart trouble and to perform secondary screens to examine the changes further. But it is already clear that even this is not enough. Gene expression, and the resultant phenotype,  are deeply influenced by environment, and many of these mice are raised in a stressed environment for the purposes of experiments, for example, being_subject to infection or fed highfat diets. Much more will be learnt by comparing phenotype screens carried out on mutant mice raised in a normal environment, say project scientists.

    But the launch of the visionary programme comes at a time of global financial crisis. Some commission's politicians will need a lot of convincing evidence that mouse genomics is more deserving of funds than other scientific projects.

    And genome engineer Francis Stewart of the Technical University of Dresden, Germany, says that focusing on the commercial  benefits  of  the  project  misses  the  point. “Through the IMPC, we have a historic opportunity to systematically learn everything about a mammal for the first time”he says. “Let's not lose the vision by sidetracking(岔开)into application issues just to please politicians.”

    1Which of the following statements is NOT true according to the passage?

    AThe mouse genome programme benefits humans if successful.

    BLiving conditions have a deep influence on gene expression.

    CBattery thinks the investment in the project will actually save money in the future.

    DIMPC finds that it will take about three years to complete its task.

    2The underlined phrase “being subject to” in Paragraph 7   means“________”

    Ataking to                         Bsuffering from

    Cseeing to                         Dlooking forward to

    3What's the aim of the IMPC according to the passage?

    ATo make mouse “clinics” spread around the world.

    BTo gain commercial benefits from the programme.

    CTo create viable strains from mice.

    DTo apply for fund to please politicians.

    4Which of the following is the most suitable title for this passage?

    AMouse project to find each gene's role.

    BHow to carry out the mouse project.

    CHow to prevent human diseases.

    DMore money needs to be raised for the mouse project.

    A close friend of mine lives with six hundreds wild animals on an island. Ever since he left schoolhe traveled all over the world, collect animals for his own zoo. He writes books about his travels and about the wild and wonderful animals what he collects. The money from the books helps to pay for the food that these animals eat.

    My friend told to me that when he was out looking for water last week, he found oil. He need money for his travel and for his zoo and a few oil would buy enough water for a life time, however he knows that if he tells somebody else about itit would be the end of his zoo and his life's work. So she will not tell anybody about what he found—because oil and water do not mix.
