  還有一篇是提到New Zealand,rats什么的。。。

  【V2】 by QQ群熱心網(wǎng)友

  歷史上有人認(rèn)為人們到達(dá)新西蘭不是特別早,然后最近人們通過(guò)carbon date老鼠的骨頭發(fā)現(xiàn)其實(shí)公元2000年前人就來(lái)了。在接下來(lái)又有人證明這個(gè)結(jié)論是錯(cuò)的。所以最后還是最之前的那個(gè)結(jié)論說(shuō),人們到達(dá)新西蘭不是很早。

  有個(gè)題:文中說(shuō)因?yàn)槿藗儊?lái)的不是那么早,所以人們帶來(lái)的水土流失什么的都是最近600年之間發(fā)生的,問這句話可以infer什么

  寂靜貌似中了 新西蘭老鼠那個(gè),但題目和寂靜上的都不一樣。高亮了一個(gè)句子,問是什么作用,和寂靜上不一樣。

  【V3】小丹尼爾

  有一個(gè)閱讀非常長(zhǎng),關(guān)于carbon dating的,首段說(shuō)到CD的不好的地方,需要的樣本大,而且不夠precise,之后提出了另外一種方法,新的方法可以使用少的數(shù)量確認(rèn)的更加精確,并且舉例,有考到舉例內(nèi)容。三大段。閱讀一屏半,題目比較簡(jiǎn)單。

  ※ 往屆考古:未確認(rèn)

  二、段落大意(英文經(jīng)狗主確認(rèn)與原文無(wú)關(guān))

  P1. 爭(zhēng)論紐西蘭什么時(shí)候開始有人居住。一開始有科學(xué)家從老鼠的骨骼化驗(yàn)中(用carbon dating技術(shù) 追溯到那么久)推出在公元前200年就有人把老鼠帶到了紐西蘭。但是由于后一種說(shuō)法一直沒有一個(gè)確切的考古發(fā)現(xiàn)(errors added in the lab),所以受到反對(duì)者的批判。/然后說(shuō)因?yàn)闆]有任何其他證據(jù)可以表明XX人arrive so early, 所以這個(gè)數(shù)據(jù)的得出一定是實(shí)驗(yàn)中出了問題。

  P2. Recently, 某team/科學(xué)家O用更好的carbon dating技術(shù)去研究the rat bone found in the same site of 1996 (同一地點(diǎn),但不是同一個(gè)sample,此處有選項(xiàng)),但結(jié)果發(fā)現(xiàn)是從12世紀(jì)末才有人到紐西蘭,所以說(shuō)明了之前那個(gè)實(shí)驗(yàn)的確有問題。In addition, 他們還發(fā)現(xiàn)了the oldest site有一些種子是4000年前的,但是那些有一些有老鼠咬痕的咬痕都是1280年的。然后接下來(lái)又說(shuō)因?yàn)樽C據(jù)表明XX人沒那么早出現(xiàn),所以他們引起的什么森林退化啊物種滅絕啊也沒那么早開始。

  P3. 最后一段說(shuō)氣候和生態(tài)變化的罪魁禍?zhǔn)滓匦屡卸ā7瘩g之前有人說(shuō)人類在AD300去了之后導(dǎo)致了鳥和frog的滅絕。實(shí)驗(yàn)很重要,確定了關(guān)于人類和老鼠的出現(xiàn)所造成的破壞(破壞森林,而且老鼠還導(dǎo)致了幾種鳥類的滅亡)的時(shí)間應(yīng)該是十三世紀(jì)之后 / 這個(gè)結(jié)果devastate在新西蘭人類對(duì)環(huán)境的影響,doresting…并沒有那么早開始…Dorestation 不是在2000年前開始的,而是在600年前才開始的。

  二、題目

  Q1. 主旨題

  V1 我選的是證明說(shuō)人類最早出現(xiàn)在BC200的那個(gè)(from考古)

  V2說(shuō)明了一個(gè)研究,并且用這個(gè)研究去反對(duì)前面研究的結(jié)果 (from考古)

  V3 provide evidence that....

  V3狗主解釋:大意就是說(shuō)之前的那個(gè)說(shuō)法有問題,但是重點(diǎn)在解釋evidence上,所以我選了這個(gè)

  Q2. 有一題考的是第三段中的research說(shuō)明一下哪個(gè)是對(duì)的

  Q3. 有一題目是說(shuō)最后一段(第三段)的作用

  我選的是這個(gè)研究結(jié)果對(duì)其他領(lǐng)域研究的影響

  Q4. 還有題說(shuō)怎樣能使某team的說(shuō)法不成立

  我選的是那些種子上的咬痕是別的動(dòng)物的…(不確定)

  Q5. 還有題問哪個(gè)是正確的

  A 某team research 很surprise地發(fā)現(xiàn)是1280年的(錯(cuò),因?yàn)楹椭皉esearch 相符)

  B 某team 的sample和96年的是一致的

  C 96年的research 沒看到4000年的種子作為證據(jù)…(有可能是另外題里的…)

  Q6. 有道推斷題

  我選的是生態(tài)系統(tǒng)改變是人類活動(dòng)和其它因素(本月V31狗主)

  狗主解釋:因?yàn)轭}目中有說(shuō)rat使很多物種滅絕

  還有個(gè)選項(xiàng)是drostation是幾種鳥類的滅絕導(dǎo)致的

  Q7. 從老鼠咬痕證明新西蘭人是AD1200年以后出現(xiàn)的,而不是BC200.考題。/文章最后一段是說(shuō),人類最早出現(xiàn)在AD1200-1300的證據(jù)說(shuō)明dorest一系列生態(tài)現(xiàn)象的發(fā)生不是2000年前,而是600年前,這句話有考題 /第二段說(shuō)誰(shuí)在哪兒發(fā)現(xiàn)了rat的骨頭還是化石好像,總之最后說(shuō)那個(gè)地方有人類有生物被污染是近600年的事(這是到考題)

  Q8. 好像是說(shuō)第一段里面說(shuō)這個(gè)實(shí)驗(yàn)有問題的人持什么觀點(diǎn)。

  有一個(gè)選項(xiàng)說(shuō)他的結(jié)論是基于O科學(xué)家的研究結(jié)果。因?yàn)镺的研究是recently的,而那個(gè)觀點(diǎn)好像之前就出現(xiàn)了所以我沒選。這題每個(gè)選項(xiàng)都很陷阱,要推敲一下。

  Q9. 疑似Q5的選項(xiàng)之一: 某team用更好carbon dating的技術(shù)去研究the rat bone found in the same site of 1996 (同一地點(diǎn),但不是同一個(gè)sample,此處有選項(xiàng))

  Q10. 還有一到是根據(jù)文章 可以推斷以下那項(xiàng)是對(duì)的

  就是根據(jù)文章細(xì)節(jié) 具體選項(xiàng)我忘了,但是有什么 humans beings 2000 years ago

  三、備注

  文章不難,一會(huì)兒就能看完,題目也還好

  Rodent Bones of Contention

  Rats caught a free ride to New Zealand when they hopped aboardthe boats of early Polynesian explorers. Now, their ancient bonesmay help pinpoint when humans first set foot on the island.Carbon-dating of bones from the rodents indicates that peoplereached New Zealand around 1280 or later, rejecting previousresearch that suggested humans may have landed there more than 1400years earlier.

  Although most anthropologists think that humans first arrived inNew Zealand around 1250 to 1300, a minority holds that people mighthave set foot on the island as early as 200 B.C.E. That conclusionis based on 1996 research that carbon-dated bones of rats, whichare thought to have been brought to New Zealand by humans either asstowaways or for food. But this study has been controversialbecause there&aposs no evidence of human settlements at that time. Somecritics have suggested that the carbon dates were due to a laberror in preparing the bones.

  To help clear up the confusion, a team led by Janet Wilmshurst,a paleoecologist at environmental research organization LandcareResearch in Lincoln, New Zealand, used a different preparationtechnique that is thought to be more accurate. The researchersobtained 17 bones from the two excavation sites where the oldestrat remains had been found. Carbon-dating with the improved methodindicated that the new bones were from 1280 or later. When theresearchers tried the new technique on some of the bones from theprevious study, all of them dated to later than 1280, indicatingthat the earlier research was flawed. The researchers nextcarbon-dated ancient seeds that the rats had gnawed and that camrom one of the excavation sites. The results gave a date of 1290or later, confirming that humans did not arrive until 1280 at theearliest, the researchers report in the 3 June issue of theProceedings of the National Academy of Sciences.

  Ian Smith, an anthropologist at the University of Otago in NewZealand, says the finding "provides convincing evidence against theassertion that either rats or people reached New Zealand prior tothe 13th century A.D." He adds that the later arrival indicatesthat humans&apos devastating impact on New Zealand, which has includeddorestation and the extinction of birds and marine mammals,happened in only 600 years, versus more than 2000 years if theinitial bone dating had been confirmed.

  David Lowe, a soil scientist at the University of Waikato inHamilton, New Zealand, says the findings also indicate that "thedestruction caused by the rats in New Zealand has been pronouncedand very fast indeed." The rats wiped out several species,including some birds and frogs. Wilmshurst adds that the speed ofdestruction "makes the risk to currently declining populations ofrat-sensitive species more pressing as they could be diminishingfaster than previously assumed."

  以上就是關(guān)于GMAT機(jī)經(jīng)的全部?jī)?nèi)容,考生朋友可以有選擇的看看,最后需要提醒各位的是,GMAT機(jī)經(jīng)雖然會(huì)對(duì)我們解題有所幫助,但是在考場(chǎng)中即使題目很像也要避免秒選,最后祝大家都能考出好成績(jī)。
