    Global Cancer Rates to Rise by 50% by 2020

    The number of new cancer cases worldwide is expected to increase by 50%by the year
    2020.But a new report suggests that as many as a third of new cancers could be avoided
    by adopting healthier lifestyles and through public health action.
    The World Cancer Report,released by the International Agency for Research on
    Cancer,shows that cancer has now emerged as a major public health threat in developing
    countries as well as rich ones.
    Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries
    more than a quarter of all deaths are caused by cancer.
    The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that
    number is expected to rise to 15 million by 2020.Researchers say most of that increase will
    mainly be due to steadily aging populations in both developed and developing countries and
    current trends in smoking and other unhealthy habits.
    "Cancer has emerged as a major public health problem in developing countries for the
    first time, matching its effect in industrialized(工业化的)countries , " said researcher Paul
    Kleihues,MD,director of IARC,in a news release."Once considered a'Western'
    disease,the Report highlights that more than 50 percent of the world's cancer burden,in
    terms of both numbers of cases and deaths,already occurs in developing countries."
    The risk of being diagnosed with cancer in developed countries is double that in less-
    developed ones.However,the risk of dying from cancer is much higher in developing
    countries , where 80% of cancer patients already have late-stage incurable tumors(肿瘤)
    at the time of diagnosis.
    Researchers say cancer rates have traditionally been higher in developed countries due
    to greater exposure to tobacco,occupational carcinogens(致癌物),and an unhealthy
    Western diet and lifestyle.As less-developed countries become industrialized and more
    prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen
    in the West,which increase cancer rates.

    According to Paul Kleihues,cancer was once regarded as
    A:an incurable disease.
    B:a mysterious disease.
    C:a"Western"disease.
    D:a world disease.

    答案:C

  • 第4题:

    The beautiful mountain village__________ we spent our holiday last year is locatedin __________ is now part of Guangxi.

    A.which ; where
    B.where; what
    C.that ; what
    D.when ; which

    答案:B
    解析:
    where在此充当地点状语,what既充当located in的宾语又充当is的主语,本题考查定语从句和名词性从句。mountain village在定语从句we spent our holiday last year作地点状语,故用关系副词where:第二个考查宾语从句,从句中缺少主语,故用what作主语。故选B。
