    点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
    2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
    3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．

    My brother used to ask me question whenever he did his homework，that made me annoyed．But every time he accepted my explanations I feel that I was the smartest person in the world．Answered his questions，I always liked to say that he was so stupid to solve such simple problems．
    Last week both of them got the report cards from our school．Unexpectedly，I got a lot of Bs，though he got As．To make things worse，all that day my brother screamed how foolish it was for me not to ask questions!I could say nothing but admit that he was right．I have never made a fun of him since then．

    6．One morning more than thirty years ago，I entered the Track Kitchen，a restaurant where everyone from the humblest（卑微的） to the most powerful came for breakfast．I noticed an empty chair next to an elderly，unshaven man，who looked somewhat disheveled．He was wearing a worn-out hat and was alone．I asked if I might join him．He agreed quietly and I sat down to have my breakfast．
    We cautiously began a conversation and spoke about a wide ange of things．We never introduced ourselves．I was concerned that he might have no money and not be able to afford something to eat．So as I rose to go back to the counter and buy a second cup of coffee，I asked，
    "May I get you something？"
    "A coffee would be nice．"

    "Who？"
    "The man you were sitting with．He is chairman of the Board of Churchill Downs．"
    I could hardly believe it．I was buying，offering a free breakfast，and feeling pity for one of the world's richest and most powerful men!
    My few minutes with Mr．Galbreath changed my life．Now I try to treat everyone with respect，no matter who I think they are，and no matter another human being with kindness and sincerity．

    3．Loren Gladstone of Toronto is 58，but thinking over how to bequeath （遗赠） his digital property（财产）．Doing the paperwork after his parents'death was a challenge．"When my time comes，I wonder if my children will even know what paper is，"he says．As a software developer，his virtual property is both valuable and vital to his business．That reflects a problem．Online lives have increasing economic and emotional value．But testamentary （遗嘱） laws offer confusing and incomplete ways of bequeathing and inheriting （继承） them．
    Digital property may include software，websites，downloaded content，online gaming identities，social-media accounts and even e-mails．In Britain alone holdings of digital music may be worth over￡9billion （14billion）．AfifthofrespondentstoaChineselocal-newspapersurveysaidtheyhadover5，000yuan（790）of digital property．And value does not lie only in money．"Anyone with kids under 14years old probably has two prints of them and the rest are in online galleries，"says Nathan Lustig of Entrustet，a company that helps people manage digital property．
    Service providers have different rules-and few state them clearly in their terms and conditions．Many give users a personal right to use an account，but nobody else，even after death．Facebook allows relatives to close an account or turn it into a memorial page．Gmail （run by Google） will provide copies of e-mails to an executor （遗嘱执行人）．Music downloaded via iTunes is held under a license which can be abolished on death．Apple declined to comment on the record on this or other policies．All e-mail and data on its iCloud service are deleted on the death of the owner．
    This has led to cases to court in America．In 2004the family of Justin Ellsworth，an army man killed in Iraq，took Yahoo!to court in Michigan to get copies of his e-mails．This year，a court in Oregon ruled that another American mother whose son had died could use her dead son's password to enter his Facebook account for a short period．Now five American states have made laws giving executors control over the social-networking accounts of dead users．
    But this raises the subject of privacy．Passing music on is one thing； not everyone may want their relatives to read their e-mails．Colin Pearson，a London-based lawyer，says access should come only with a clear provision in a will．
    But laws，wills and password safes may be contrary to the providers'terms of service，especially when the executor is in one country and the data in another．Headaches for the living and lots of lovely work for lawyers．

    40．Why does Loren begin to think over how to bequeath his digital property at the age of 58？B
    A．Because he is afraid his children don't know what paper is．
    B．Because there's no complete law dealing with digital property．
    C．Because his digital property is of great value and importance．
    D．Because he is worried his children will be taken to court．
    41．Which of the following can be inferred from the passage？D
    A．Digital property is assessed in terms of nothing except money．
    B．No laws in America have been made to deal with digital property．
    C．The relatives may read the e-mail of the dead without permission．
    D．Lawyers can make money through cases about digital property．
    42．Facebook，Google and Apple have a similar rule thatA．
    A．users are offered accounts used by nobody else except users themselves
    B．relatives of the dead may close an account or use it at their own will
    C．the executor may enter the e-mail and read it by themselves at any time
    D．the data downloaded by the dead will be copied and then deleted from net
    43．Which of the following can best serve as the title of the passage？C
    A．Digital Information      B．Testamentary Laws
    C．Deathless Data           D．Vital Property．

    Harry used these prison escapes to build his fame．He arranged to escape from the local prison of every town he visited．In the afternoon，the people of the town would read about it in their local newspapers，and in the evening every seat in the local theater would be full．What was the result？Worldwide fame and a name remembered today．
