  • [单选题](C)The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.
  • A. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
    B. Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
    C. "The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
    D. At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.
    E. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
    F. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
    G. Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
    H. 72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.
    I. the extinguishing of the Olympic torch
    J. the collapse of broadcasting systems
    K. the transportation breakdown in London
    L. the destruction of weather satellites

    C. 张自新,初名鸿,字子宾,苏州昆山人。自新少读书,敏慧绝出。古经中疑义,群子弟屹屹①未有所得,自新随口而应,若素了者。性方简,无文饰。见之者莫不讪笑,目为乡里人。同舍生夜读,倦睡去,自新以灯檠投之,油污满几,正色切责,若老师然。髫龀丧父,家计不能支。母曰:“吾见人家读书,期望青紫②,万不得一。且命已至此,何以为书?”自新涕泣长跪,曰:“亡父以此命鸿,且死,未闻有他语,鸿何敢忘?且鸿宁以衣食忧吾母耶?”与其兄耕田度日,带笠荷锄,面色黧黑。夜归,则正襟危坐,啸歌古人,飘飘然若在世外,不知贫贱之为戚也。
    D. 兄为里长,里多逃亡,输纳无所出。每岁终,官府催科,搒掠无完肤。自新辄诣县自代,而匿其兄他所。县吏怪其意气。方授杖,辄止之,曰:“而何人者?”自新曰:“里长,实书生也。”试之文,立就,慰而免之。
    E. 自新视豪势眇然不为意。吴中子弟多轻儇③,冶鲜好衣服,相聚集,以亵语戏笑,自新一切不省,与之语,不答。议论古今,意气慷慨。酒酣,大声曰:“宰天下竟何如?”目直上视,气勃勃若怒,群儿至欲殴之。补学官弟子员,学官索贽金甚急,自新实无所出,数召笞辱,意忽忽不乐,欲弃去,俄得疾卒。
    F. 归子曰:余与自新游最久,见其面斥人过,使人无所容。俦人广坐间,出一语未尝视人颜色。笑骂纷集,殊不为意。其自信如此。以自新之才,使之有所用,必有以自见者。沦没至此,天可问邪?余悲自新之死,为之叙列其事。
