With the development of electronic publishing,many medical journals now have Web sites on the Internet,and some journals are pub-lished only online.A few medical journals,like the Journal of the American Medical Associa-tion,are considered general medical journals because they cover many fields of medicine.Most medical journals are specialty journals that focus on a particular area of medicine.

    Medical Journals

    Medical journals are publications that report medical information to physicians and other
    health professionals.
    In the past,these journals were available only in print.With the development of electronic publishing,
    many medical journals now have Web sites on the Internet,and some journals are published only online.A
    few medical journals,like the Journal of the American Medical Association,are considered general medical
    journals because they cover many fields of medicine.Most medical journals are specialty journals that focus
    on a particular area of medicine.
    Medical journals publish many types of articles.Research articles report the results of research studies
    on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of
    different treatments.Review articles summarize and analyze、the information available on a specific topic
    based on a careful search of the medical literature.Because the results of individual research studies can be
    affected by many factors,combining results from different studies on the same topic can be helpful in reaching
    conclusions about the scientific evidence for preventing,diagnosing or treating a particular disease.Case
    conferences and case reports may be published in medical journals to educate physicians about particular
    illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the
    authors,often regarding a research or review article published in the same issue.Editorials provide a per-
    spective on how the current article fits with other information on the same topic.Letters to the editor provide
    it way for readers of the medical journal to express comments,questions or criticisms about articles published
    in that journal.

    A:Five.
    B:Seven.
    C:Four.
    D:Six.

    答案：A
    解析：
    由文章第一段“Medical journals are publications that report medical information tophysicians and other health professionals.”可知，内科医生和其他健康专业人士是医学杂志的主 要读者。故答案为B。
    被选项在内容上都是涉及到“医疗杂志的出版”，所以借助publish作为答案线索，发现 与答案相关句："many medical journals now have Websites on the Internet（该句与A内容一致）, and some journals publish only online.（该句直接与C矛盾）A few medical journals, like the Jour- nal of the American Medical Association,are considered general medical journals because they cov- er many fields of medicine.（该句与B内容一致）Most medical journals are specialty journals that focus on。particular area of medicine.（该句与D内容一致）。”故选C。

    根据题干中的核心结构different studies on the same topic作为线索，找到答案相关句： "Review articles summarize and analyze the information available on a specific topic based on acareful search of the medical literature."（该句说“综述文章是在对医学文献进行了仔细的查询 后找出的对有关某一具体主题的信息进行的汇总和分析”) "Because the results of individual research studies can be affected by many factors,combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing,diag- nosing or treating a particular disease."(“对于同一主题的不同研究结果的汇总”在含义上与上 句“综述文章”的目的一致），因此判断选B。
    由文章最后一段最后一句“Letters to the editor provide a way for readers of the medical journal to express comments,questions or criticisms about articles published in that journal.”可知， 给编者的信使读者能够对杂志上发表的文章进行评论、提出问题或提出批评意见。第三篇 本篇文章主要讲述的是核辐射对人体的危害，以及可能导致的严重后果。
