    A．come to powerB．come into effect

    分析 一项禁止青少年吸烟的新法案将在首长签字九十天后生效．

    解答 答案：B．
    come into effect生效；come to power掌权；make an effect影响；make a difference有意义；句中after连接的时间状语从句表示动作未发生，根据句意应该是九十天后生效的意思．故选B．

    7．Many people to newspaper and magazines to express their opinions．Letters to the editor must carry the writer full name，address and telephone number，although the information is not necessary for publication．This requirement to provide personal particulars is a clear indication that writers are held responsible for what they say．When a writer wants his voice heard．He needs to claim ownership of his voice．Responsibility is the name of the game．
    "People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship，"said social worker Ken Yip，"and this is what is causing a lot of family problems．"When we sign a paper，for example，a business contract or a bank document，the signature is symbol of consent，an agreement to take the matter seriously．Most governments and many organizations will not process writer's complaints if they do not bear the writer's signature．The absence of a signature，they explain，tells us that the writer cannot be too serious and therefore does not deserve a reply．
      There are people who wish to remain anonymous（匿名的）for various reasons．Multi-billionaire Mr．King donates generously to charity several times a year．He gives simply because he wants to help but not for the publicity his donations may bring，and he does not want his good deeds to make news．In other cases，people insist on anonymity because they are afraid of the consequences of revealing their identity．Crime witnesses may be willing to assist the police，but most are unwilling to give their names when reporting a crime．
      Name or no name？The answer is very personal and lies in how much we want to get involved．We all have a name，it is a matter if responsibility to it when we make a statement，a claim or an accusation．We all want to honour our own name，and it is only by stamping our expression of an opinion with our own name that we honour what we say．

    68．What does the writer mean by saying"Responsibility is the name of the game"？D
    A．Writers need to provide their personal information in the game．
    B．Publication must bear the writer's full name，address and phone number．
    C．Writers should be responsible for their names．
    D．Names are required to indicate writers'responsibility for what they say．
    69．The second paragraph suggests that a paper without a signature mayB．
    A．help to end a relationship
    B．not get a reply
    C．be accepted all the same
    D．become a family problem
    70．Some people don't want their names known because they areB．
    A．hesitant to make a donation
    B．unwilling to draw public attention
    C．afraid of an accusation
    D．ready for involvement
    71．The passage is mainly aboutC．
    A．honour and writers
    B．identity and signature
    C．signature and responsibility
    D．anonymity and signature．

    4．Do you ever wish for a little more time to do everything you need to do？Well，on July 1 you'll be getting it--but only one more second．
      On July 1 at exactly 7：59：59 a．m．Beijing time （or on June 30 at 23：59：59 UTC，Coordinated Universal Time），the world's atomic（原子的） clocks will pause for a single second，or，more precisely，change to the unusual time of 7：59：60，according to theverge．com．The addition of a leap second（闰秒），announced by the Paris Observatory，is to keep our clocks in time with the slowing of Earth's rotation（旋转） and astronomical time as measured by the sun．
       Just one extra second could cause big problems and affect the way computers and websites work，however．When the last leap second was added back in 2012，more than a few websites had some trouble．As reported by Phys．org，popular sites like the community website Reddit crashed when the leap second was added．
      For Reddit，the problem was eventually found to be with a Linux system that got confused when it checked the network time and found an extra second．
      Speaking to Wired about the problem back in 2012，Linux creator Linus Torvalds commented："Almost every time we have a leap second，we find something．It's really annoying，because it's code （代码）that is almost never used，and thus not tested by users under their normal conditions．"
      Companies have had to think of their own solutions，and Google's"leap smear"may be the best-known example．As company engineer Christopher Pascoe explains in a blog post，companies usually try to fix the problem by turning back the clocks by one second at the end of the day so that they play that second again．
      However，Pascoe believes this creates problems．He asked："What happens？Does e-mail that comes in during that second get stored correctly？"
      Google has a solution：Cut the extra second into milliseconds and then put these tiny amounts of time into the system throughout the day．"This means that when it became time to add an extra second at midnight，"says Pascoe．"Our clocks have already taken into account over the course of the day．"
      For many companies without Google's money，however，the leap second will likely still cause some crashes．Don't worry，though-at least it won't last long!

    51．Why do we need to add a leap second？C
    A．The world's atomic clocks are set to do so．
    B．To keep in time with the world's computers．
    C．To keep atomic clocks in time with the slowing of Earth's rotation．
    D．To record the changes to astronomical time．
    52．What happened to the website Reddit when the leap second was added in 2012？D
    A．It crashed because of a virus attack．
    B．Its network time added two extra seconds．
    C．All of the code in its Linux system went wrong．
    D．One of its software systems got confused and the site broke down．
    53．What does the underlined word"something"refer to in the 5th paragraph？A
    A．The code not working properly．
    B．The extra second．
    C．The problem．
    D．Normal conditions．
    54．How do companies usually deal with the problem of the extra second？C
    A．By shutting down computers at the end of the day．
    B．By stopping receiving emails that come in during that second．
    C．By turning the clocks back by one second at the end of the day．
    D．By cutting the extra second into milliseconds throughout  the day．
    55．What's Christopher Pascoe's attitude toward Google's solution to the problem？C
    A．Unfavorable   
    B．Doubtful  
    C．Approving  
    D．Cautious．
