  分數(shù)很一般,擼主之前看了很多機經(jīng),特別是托福的機經(jīng)三次speaking和writing都中了,所以來回饋一下。
  雖然這次Verbal沒中一個或者我沒看到。
  ISSUE:5 Claim: Governments must ensure that their major cities receive the financial support they need in order to thrive.
  Reason: It is primarily in cities that a nation's cultural traditions are preserved and generated.
  Argue:17、The following appeared in a memorandum from the manager of WWAC radio station.
  "To reverse a decline in listener numbers, our owners have decided that WWAC must change from its current rock-music format. The decline has occurred despite population growth in our listening area, but that growth has resulted mainly from people moving here after their retirement. We must make listeners of these new residents. We could switch to a music format tailored to their tastes, but a continuing decline in local sales of recorded music suggests limited interest in music. Instead we should change to a news and talk format, a form of radio that is increasingly popular in our area."
  數(shù)學:
  1.n和m都是正整數(shù),m是2^6的一個因子,問所有整數(shù)中,能同時和3n,(2^6)/m這兩個數(shù)相等的個數(shù)最多是多少?
  因為3n是3的倍數(shù),而(2^6)/m只含有因子2,所以不可能整數(shù)同時和這兩數(shù)相等,選0個。
  2. 一個立方體中放了一個圓柱,圓柱底面內(nèi)切于立方體底面,高和立方體相同,問體積比最接近的值。答案:3:4
  3.K<2,問在1,2,3,k,2k中,有可能成為中位數(shù)的有哪些?答案 1,2,2k
  4.一個人騎車,上坡15miles/hour的速度騎了5miles,然后下坡5miles,問下坡速度多少才能使平均速度達到20mile/hour。答案30miles 這題不能簡單的20*2-15=25,因為上下坡的時間不一樣,平均速度不可能是上坡速度+下坡速度除以2,要按照 “速度=路程/時間”嚴格推。
  5.有3個數(shù)列,分別有X,Y,Z個數(shù)(xyz都是奇數(shù)),這3個數(shù)列中位數(shù)都是52,問把這三個數(shù)列合并后的中位數(shù),和52比較。答案:相等。
  貌似就沒什么難題的。
  填空:
  1.minor misgivings 一個作者的觀點還是作品, critics of this author’s acclaim that。。。 is thoroughly_____ 選項1.absurd 2.understandable 我選的的absurd。。
  2.國會在做決定時一般都會聽取大多數(shù)人的意見以為他們擔心失去大多數(shù)的支持,如果一個沒得到大多數(shù)人支持的決定沒起到應(yīng)有作用,就會引起政治沖突。
  三空題, 第一個是聽取意見,第二個擔心(fear of),第三個引起沖突 具體單詞忘了
  3.一個正向重復的題,number of XXX 會___ the rate of OOO,因為 the greater of XXX, the more increase of OOO, 我選的accelerate,還有一個詞沒選出來,另外5個單詞都沒看出有accelerate的意思
  4.一個叫S的地方被認為是britain的首先建立的city, 但是后來發(fā)現(xiàn)在britain 的其他sites 發(fā)現(xiàn)了比S更早的證據(jù),。。。(不記得了)
  三空題,就記得第一個控established as
  其他單詞:deplorable,
  閱讀
  1.一個作家以高雅的描繪而著稱,但是卻忽略了她subject to matters的特性。她總是被認為描寫一個高雅的東西,但實際上她描寫了很多窮人和下等階級。
  2.科學家一直認為comet 上的溫度是零度,(轉(zhuǎn)折)但是新的發(fā)現(xiàn)通過2個技術(shù)(有題,3選2,選這2個技術(shù))覺得溫度不會是零度, (再次轉(zhuǎn)折), 很多astronaut 堅持認為是零度,并且反駁這個新的發(fā)現(xiàn)。
  3.長篇(4道題):全球變冷,which is result from the same reason of 全球變暖(有題,答案就是全球變暖和全球變冷都來自一個原因,好像原因就是二氧化碳),然后又說全球變暖主要是在晚上和冬天,而全球變冷體現(xiàn)在past 40years 的day time temperature 下降了0.5度(有題)。
  第二段是全球變冷地球whole 變冷,而是balance the temperature between 一個地方 with 另一個地方,然后說全球變冷在中高緯度的北美地區(qū)是different的(有題)。
  第三段講什么忘了。
  4. 森林化減少二氧化碳,通過重新種樹,或者在以前沒樹的地方種樹來森林化,但是通過這2個技術(shù)產(chǎn)生的森林是vulnerable的,然后又說森林的bettles,因為氣候warm了,所以更多,更活躍,產(chǎn)生更多的二氧化碳(有題),然后又說第二種技術(shù)會涉及到很多其他的阻礙因素,比如農(nóng)民選擇什么樣的樹來種植,怎么樣來栽培,還有經(jīng)濟利益,政策等等。(農(nóng)民種樹這個地方有題)。
  補充一下 森林化那篇是JJ。。文章如下:
  Globally, the combination of reforestation and afforestation activities could reduce atmospheric CO2 concentrations by as much as 30 parts per million (ppm) this century (House et al. 2002). However, this potential mitigation is limited by many factors. One is the vulnerability of forests to increased disturbances, including those caused by pathogens, droughts, fires, and storms (Galik and Jackson 2009). For example, the mountain pine beetle is projected to convert 374,000 square kilometers (km2) of pine forest from a small net carbon sink to a large carbon source in Alberta alone, liberating 1 billion tCO2e to the atmosphere (Kurz et al. 2008). Climate change is another factor that could limit the potential for carbon sequestration in forests. The mountain pine beetle in Alberta is thriving in part because of warmer minimum temperatures in the winter and warmer and drier summers. A third potential limitation is landowner behavior in private-sector forestry, including decisions on what species to plant and how intensely to manage forests. Private forestry competes economically with agriculture, urban development, and other land uses. Landowner decisions will therefore dictate the success of some climate policy efforts, a topic we explore next.
