    U. S. States Do Poorly in Women's Health

    Not a single U. S. state meets basic federal goals for women's health,and the nation
    as a whole fails except in two areas一mammograms(乳腺X光照片)and dental(牙齿的)
    check-ups一researchers said on Thursday.
    Millions of women lack health insurance,and states make it difficult to enroll(加入)in
    Medicaid,the state-federal health insurance plan for the poor,according to the report.
    And few states are doing anywhere near enough to help women quit smoking一the
    leading cause of death in the United States.
    "The nation as a whole and the individual states fall short of meeting national goals,"
    reads the report,put together by the National Women's Law Center and the Oregon
    Health&Science University."These health goals provide a road map for assessing the
    status of women's health."
    Of 27 measures examined by the group,from screening for diseases to actually treating
    them,the nation passes on only two,the researchers said."The nation is so far from the
    health goals that it receives an overall grade of'unsatisfactory',"they wrote.
    The problem seems to be a lack among states of an overall plan for health in general,
    the NWLC said.
    " State policy makers' piecemeal(一件一件做的)approach to our health care crisis has
    resulted in a complex and ineffective system that fails to meet the health care needs of
    women,"Judy Waxman,NWLC Vice President for Health,said in a statement.
    "Lawmakers need to take a comprehensive,long-term approach to meeting women's
    health needs and tackle this serious problem that troubles so many families."

  • 第2题:

    In some libraries young people can check out ten juvenile books at one time.

    A:adventure
    B:large-print
    C:hardcover
    D:children's

    答案:D
    解析:
    本句意思:在一些图书馆年轻人可以一次同时查阅十本青少年书籍。adventure的意思 为“冒险的,惊险的”;large-print的意思为“用大号铅字排印的”;hardcover的意思为“精装的, 硬书皮的”;children' s的意思为“孩子们的”。juvenile的意思为“青少年的”,和children' s的 意思接近。
