2011年考博英語(yǔ)完形填空詞匯
    例1.For example,it has long been known that total sleep_____is 100 percent fatal to rats.
    A.reduction B.destruction C.deprivation D.restriction
    【答案】C
    【解析】reduction意為“減少”;destruction意為“破壞”;deprivation意為“剝奪,喪失”;而restriction意為“限制”。題意為“完全剝奪老鼠的睡眠對(duì)它而言是致命的”,所以C選項(xiàng)Deprivation最合適。
    例2.Many old people in the cities find themselves unable to get used to the rapid______of city life.
    A.rate B.speed C.step D.pace
    【答案】D
    【解析】所給的四個(gè)選項(xiàng)詞義接近,rate最常見(jiàn)的詞義為“率,”pass rate“”,exchange rate“;交換率”,inflation rate“通貨膨漲率”;speed 的詞義是“速度”。at a speed/rate of 100km an hour“以每小時(shí)100公里的速度”,再該搭配中,rate和 speed同義;不過(guò),walk with slow steps“行走緩慢”,step意為“腳步”;”only a few paces/steps away“僅僅幾步之遙”,這里的space 和step可相互替換;the pace of life“生活的節(jié)奏”,這正是本句上下文所需要的詞義。故答案為D項(xiàng)。
    例3.They have got everything ready to make a _______ across the Atlantic.
    A.trip B.travel C.voyage D.journey
    【答窠】C
    【解析】voyage的意思是“航行”。以上詞匯題所提供的四個(gè)詞的含義很相似,均有“旅行”之意.但它們各有側(cè)重。trip指娛樂(lè)性的旅行,travel是指到各處旅行,voyage指航行,Journey是指到某地去旅行。根據(jù)題意,特別根據(jù)Atlantic(大西洋)一詞,得出C選項(xiàng)voyage為正確選擇。要解好此類匯題,考生在復(fù)習(xí)時(shí)一定要注意區(qū)別一些容易混淆的同義詞,現(xiàn)列出一些形式不同,意思相近的詞:environment,surrounding,circumstances,atmosphere;pace.rate,speed,rhythm…
    例4.Many types of rock are______from volcanoes as solid,fragmentary material.
    A.ejected B.injected C.propelled D.flung

    注射;注入,引入,投入);propel(vt.推進(jìn),推動(dòng);激勵(lì),驅(qū)使)fling(vt.《用力地》扔,

    A.precedes B.prevails C.a(chǎn)scends D.a(chǎn)ccelerates
    【答案】D
    【解析】precede(vt.在……之前,先于);prevail(vi.流行,盛行;《over》獲勝,占優(yōu)勢(shì);《on,upon》說(shuō)服,勸說(shuō),誘使);ascend(vi.漸漸上升,升高v;vt.攀登,登上);accelerate(v. 《使》加快,《使》增速)。B項(xiàng)是非及物動(dòng)詞,后面有沒(méi)跟介詞,故肯定錯(cuò)誤。
