Y2K
     The sudden emergence of Y2K in headlines around the world is no algebraic code, nor mysterious symbol of doom. It is, very simply, shortened for the coming transition to the year 2000 in the western calendar and the problems that might and/or are likely to occur as a result of the data change. Virtually all computers and automated systems were formulated using the solar-based calendar, as opposed to the Chinese lunar calendar or other eastern calendars.
    Computers and automated systems around the world have only been using two digits in the year field in the computer code that tells the computer or automated system what to do. When there is a four-digit change in the calendar at mid-might on December 31, 1999, many computers and automated systems may malfunction unless the year field is fixed. The thinking the year is 1900. this could cause a lot of problems if electrical power grids(電極), water systems, energy supply systems, medical devices, shipping ports and airports fail or have to be closed.
     No one knows what is going to happen, but no one is immune
     No one really knows what is going to happen down to the last detail when the clock strikes the mid-night around the world on January 1,2000. the situation changes daily as more and more people learn about the problem and work hard to do something about it. The world had never experienced a millennium change with automated system and computers.
    The effects will be serious if action is not taken
     We do know this year 200 date change is serious and no family, business, community or country is immune to the Y2K problems. Virtually everyone will see some type of disruption-only the scope and impact are in question. Some, in countries where much Y2K repair work has already been done, may only see a harmless service warning light come on in their cars. others in more remote or less developed areas could be without food, water, telecommunications and/or electricity for hours, days, weeks or months. It is in everyone’s interest, around the world, to avoid serious long-term disruption that could affect the global economy and strain humanitarian efforts. But Y2K knows no national or political boundaries.
    The problem is bigger than most people around the world think it is. Most people don’t sit around thinking about or where their electricity, water and other basic supplies come from. Most people don’t really think about how telephones, medical equipment or home appliances work. Microchips are embedded in just about every automated device or system we use today. Not all will be affected by Y2K, but many will and it is important to know which devices and systems are vulnerable, fix the problem and test it again and again to make sure it will work.
     We see that computers and automated systems can do so much, and come to rely on them for the most basic services. Most of us have probably never thought about how a computer can not think on its own like a human and what that means. Many computers and automated systems are programmed to only recognize 99 years. Unless these Y2K problems are repaired, some systems will malfunction because the computer is not intelligent enough to know what year “00” stands for. Those computers and systems have to be told not to shut down, but keep working onto 2000.
    6.According to the passage, which of the following statement is true?
    A.The Y2K problem is so serious that it means the end of the world.
    B.The Y2K problem is just as simple as an algebraic code.
    C.The Y2K problem is a likely occurrence as a result of the date change.
    D.The Y2K problem is nothing to worry about.
    7.The reason for the Y2K problem to happen is that____.
    A.computer and automated system can only read two digit in the year field
    B.computers and automated systems do not recognize four digits in the year field
    C.the year field is fixed, so computers and automated systems will be out of order
    D.all of the above reasons are possible reasons for the Y2K problem to occur
    8.The sentence “But the Y2K knows no national or political boundaries” means that ____.
    A.virtually no country can be immune to the Y2K problem
    B.the Y2K problem does not consider any country as an independent country
    C.the Y2K problem considers the whole world as one country
    D.the Y2K problem can not tell national boundaries from political boundaries
    9.We can infer from the passage that ____.
    A.Y2K problems will be only damage our computers
    B.some people may be immune to Y2K problem if their computer are more advanced
    C.some people in more remote or less developed areas can be less affected by it
    D. the occurrence of Y2K is not a matter of possibility, but a matter of scope and impact.
    10. Most people around the world do not take Y2K problem seriously enough because____.
    A.most people just use electricity, telephones , medical equipment, and home appliances but do not know how they work
    B.some devices and systems are not vulnerable to Y2K problem
    C.some people d not rely on computers and automated systems at all
    D.they believe that the future computer will be more intelligent

    6.C
    這道題要求考生從給出的四個(gè)選項(xiàng)中選出一個(gè)于原文內(nèi)容相符的選項(xiàng),所以對(duì)各個(gè)選項(xiàng)分別考察即可。

    通過(guò)第二段的敘述,計(jì)算機(jī)和自動(dòng)系統(tǒng)只能識(shí)別年份域中的兩位。當(dāng)年分域中的四位發(fā)生了變化時(shí),計(jì)算機(jī)和自動(dòng)系統(tǒng)就無(wú)法識(shí)別了。另一方面,如果為了避免這一問(wèn)題而使年份域固定不變,計(jì)算機(jī)和自動(dòng)系統(tǒng)的時(shí)間會(huì)固定不變,或停止工作,或者不能正確處理日期??梢?jiàn)A,B,C都是問(wèn)題發(fā)生的原因。
    8.A
    此題考察我們對(duì)于句子the Y2K knows no national or political boundaries的理解。它的意思是:千年蟲(chóng)問(wèn)題沒(méi)有國(guó)家和政治的界限。在文章的第三和第四段中,作者指出沒(méi)有人可以不受千年蟲(chóng)問(wèn)題的影響,這一問(wèn)題帶給人們的影響無(wú)處不在。所以,千年蟲(chóng)問(wèn)題可以傳播于各個(gè)國(guó)家,沒(méi)有任何一個(gè)國(guó)家可以免受千年蟲(chóng)問(wèn)題的影響。
    9.D
    通過(guò)文章第四段的敘述,我們可以知道:沒(méi)有任何一個(gè)家庭,社會(huì)或個(gè)人可以免受千年蟲(chóng)問(wèn)題的影響,每個(gè)人都將看到千年蟲(chóng)問(wèn)題引發(fā)的某些類型的破壞,而只有影響的范圍和影響帶來(lái)的沖擊是未知的??梢?jiàn),千年蟲(chóng)問(wèn)題的發(fā)生并不是可能性的問(wèn)題,而是范圍和影響力的問(wèn)題。
    10.A
    作者在文章的第五段指出:許多人對(duì)于千年蟲(chóng)問(wèn)題還沒(méi)有給予足夠的重視,因?yàn)槲⑿托酒磺度肓宋覀兪褂蔑酱蠖鄶?shù)自動(dòng)裝置和系統(tǒng)中,這些人實(shí)際上并不知道電話機(jī),醫(yī)療設(shè)備或家用電器是怎樣工作的。因此他們還沒(méi)有意識(shí)到其實(shí)自己的生活也將受到千年蟲(chóng)問(wèn)題的影響。
