Thus we should fully recognize the potential danger of limiting our vision in one of the two sides. And only through the approach of paying equal attention to both sides could we make further achievements in the process of learning.
      Views and ideas from people agree with us may raise our confidence, strengthen our courage, and enhance our psychological satisfaction. According to common sense and our everyday experience, the propensity to accept the ideas from people who agree with us rather than the opinions from people disagree with us associates strongly with the nature of human beings, for we are social animals and it is the inner instinct of us to seek for approval of others. Imagine, what would you react if the work accomplished by your arduous efforts receives fierce criticism...

      2012GRE作文全面突破備考必讀

      05-27

      標(biāo)簽: 突破

        一. Analytical Writing Section簡介

        邏輯寫作是General GRE Test考試的三個(gè)必考部分之一,它的前身是ETS設(shè)計(jì)的寫作單項(xiàng)考試AWA(Analytical Writing Assessment)。ETS從02年10月份開始,正式將寫作單項(xiàng)考試并入GRE考試,取代原有的GRE邏輯部分(Analytical Section)。它用于評(píng)價(jià)考生的邏輯思維和英文寫作能力。即分析問題,闡述立場,論證觀點(diǎn)的能力和獨(dú)立的完成一篇中心明確邏輯嚴(yán)謹(jǐn)?shù)挠⑽奈恼碌哪芰?。在這里請(qǐng)注意:邏輯寫作不測(cè)試學(xué)生所掌握的具體知識(shí),以確保對(duì)于有不同教育背景的考生的公平性。

        新GRE寫作要求考生在30分鐘+30分鐘內(nèi)分別完成兩篇文章,它是美國所有作文考試中時(shí)間最長而質(zhì)量要求最高的一類作文考試。此外,GRE作文不僅是普林斯頓的教授給個(gè)分就算,它還要我們花錢將其寄到我們申請(qǐng)的學(xué)校,然后由這幫決定我們命運(yùn)的委員會(huì)的委員們嚴(yán)格把關(guān),看你是否在科研文章的寫作方面具備一定的水準(zhǔn),因?yàn)槟銈儗淼睦习鍖?duì)寫作的要求是比較高的,所以這自然是構(gòu)成了你能不能得到獎(jiǎng)學(xué)金的重要標(biāo)準(zhǔn)之一。當(dāng)然大家也不要怕,GRE寫作的題目是全世界公開的,有點(diǎn)像我們的開卷考試,只要花一定的精力準(zhǔn)備,再加上臨危不懼的心態(tài),一般的中國考生基本都能考到4.5分以上,所以請(qǐng)大家在準(zhǔn)備GRE寫作的第一天開始就要具備這種必勝的心態(tài)。

        從形式上講:

        邏輯寫作考試包括兩個(gè)不同的部分:

        1.Issue task(30min),要求作者根據(jù)所給題目,完成一篇表明立場的邏輯立論文。

        2.Argument task(30min),要求考生分析所給題目,完成一篇駁論文,指出并且有力的駁斥題目中的主要邏輯錯(cuò)誤。

        從特點(diǎn)上講:

        1. GRE寫作考試有題庫:

        為了達(dá)到公平,ETS公布了它考試的所有寫作題庫,那么為了達(dá)到能和native speaker一起競爭,考生應(yīng)該在考前對(duì)所有題目都進(jìn)行預(yù)習(xí)(節(jié)約考試時(shí)的審題時(shí)間),并通過100-150個(gè)提綱的寫作了解GRE寫作的一般結(jié)構(gòu),通過30-50篇寫作來練習(xí)自己的寫作思路和表達(dá)。對(duì)題庫中的題目越熟練,對(duì)考試越有利。

        2. GRE寫作考試的評(píng)閱是計(jì)件工作制的:

        每個(gè)評(píng)卷人對(duì)你文章的評(píng)閱非常快,不可能對(duì)每個(gè)細(xì)節(jié)都很仔細(xì)地去看??忌鷳?yīng)該迎合評(píng)卷人的評(píng)卷思路,用最規(guī)范的結(jié)構(gòu)和最清晰的表達(dá)來體現(xiàn)自己的思路:首段要鮮明地提出觀點(diǎn),中間段落層次要拉開,每段的開始應(yīng)該就是該段的topic sentence。

        3. GRE寫作的評(píng)分是整體評(píng)分(holistic scoring):

        首先,從ETS公布的各分?jǐn)?shù)段評(píng)分標(biāo)準(zhǔn)看,其評(píng)分主要注重以下三個(gè)方面:①、邏輯分析能力(要求insightful);②、文章的組織(要求well-organized);③、語言能力(要求standard written English; concise; varied structure等)。

        但是ETS也強(qiáng)調(diào),評(píng)分是整體的,而不是各個(gè)角度分別評(píng)分。這就說明...

      2012GRE新閱讀題答題經(jīng)驗(yàn)分享

      標(biāo)簽:

        GRE考試閱讀題答題經(jīng)驗(yàn)分享。這次GRE考試感覺很失敗的地方是閱讀。有篇長閱讀是社科類的,更準(zhǔn)確地說是藝術(shù)類的。根據(jù)我的經(jīng)驗(yàn),中國考生最害怕的就是社科類的長閱讀。這種閱讀再加幾個(gè)生詞,絕對(duì)能要你命。今年這篇我花了很多時(shí)間好好讀了,結(jié)果還是不知所云,7題全蒙的??纪陠柫艘幌聞e人,情況也都差不多。


        造成這種現(xiàn)象的原因,對(duì)于我來說,就是對(duì)美國文化了解太少。像這次那篇BT長閱讀,說的好像是什么impressionist(印象派)和modernist(現(xiàn)實(shí)主義)的東東。由于對(duì)這方面毫無了解,所以讀這篇文章毫無感覺。平心而論,哪怕再給我十分鐘我也讀不懂,所以我后來也索性放棄跨區(qū)了。

        我不是要大家去補(bǔ)習(xí)美國文化的知識(shí),這工程量太大。網(wǎng)上都說平時(shí)要多看什么economist什么的,試問有幾個(gè)人會(huì)真正為了GRE去看-


        我的建議就是,大家可以抽一點(diǎn)時(shí)間,利用相關(guān)資源(比如wikipedia),多去了解一下GRE社科類閱讀愛考的知識(shí)。憑我粗粗做完所有閱讀真題的印象,GRE社科類閱讀非常喜歡考黑人文學(xué)Black literature,黑人音樂Black music(尤其是Jazz),婦女(包括婦女地位的改變,婦女文學(xué)),藝術(shù)類包括impressionist、modernist等。另外務(wù)必多留意一下上述知識(shí)的代表人物!比如Ragtime就是Jazz的代表人物及一種風(fēng)格。并不是要求大家知道這個(gè)人物做了什么,只需要混個(gè)眼熟,考試的時(shí)候萬一碰到一大串人名,能對(duì)其中一兩個(gè)有點(diǎn)眼熟,能大概猜測(cè)出來是關(guān)于什么的就行!...

Hardly one common individual knows who their greatest thinkers are,not mention to take them seriously. Admittedly,in some cases,people claim that they admire the greatest thinkers; however,they actually know little about what the greatest thinkers’ thoughts are. The fact is,in history of human civilizations,most societies do not take their greatest thinkers seriously,even when the greatest thinkers are seemed to be respected.

      Generally,whatever societies the greatest thinkers are in,they have similar characteristics,such as high intelligence,eccentric temperament,wide range of knowledge,and the most essential one: the deeply and often predicted thoughts,which is the product of real wisdom. On one hand,it is the thoughts that distinguish the greatest thinkers from the mass. On the other hand,it is also the thoughts,however correct and predicted,which cause these elites out of the mass‘ sights and put them into an embarrassment in which few can understand them and their thoughts. A proper example is the passional German philosopher and poet Nietzche. Niet...

      2012GRE閱讀高分秘訣之排除法

      05-27

      標(biāo)簽:

        一、排除題的解題方法

        1. 精確定位排除法

        如果前兩種方法均不可以使用的話,我們就只能將選項(xiàng)精確的在文中定位,找出選項(xiàng)和閱讀文章中的對(duì)應(yīng)關(guān)系,注意選項(xiàng)中的同義代換與原文是否對(duì)應(yīng)。有時(shí)會(huì)出現(xiàn)這樣的情況,選項(xiàng)中有四個(gè)是和題目的關(guān)鍵詞定位在一個(gè)段內(nèi)的,但其中一個(gè)選項(xiàng)卻定位在了另一個(gè)段落內(nèi),那么這個(gè)選項(xiàng)就是答案。

        注意:正確答案一般是作者在文中明確反對(duì)過的,或者是根本未提到,再或者就是定位的段落未提到的(選項(xiàng)的關(guān)鍵詞落在別的段落)說法。

        2.強(qiáng)對(duì)比排除法:

        如果題目中是關(guān)于A的提問,但是原文中沒有直接給出與A相關(guān)的描述。不過,文中出現(xiàn)了與B相關(guān)的特征描述,而B呢正好是與A形成強(qiáng)烈對(duì)比的對(duì)象。那么我們只需要把B的特征取非就可以得到答案了。一般文章中會(huì)出現(xiàn)unlike,in contrast to, compared with,閱讀的過程中遇到該類別的關(guān)鍵詞注意要做筆記。

        3.無關(guān)信息排除法:

        如果某一個(gè)選項(xiàng)和文章大意沒有關(guān)系或者根本沒有提到過,那么它一定就是正確答案了。因此,在閱讀的過程中要留意文章每段的中心意思,理出文章的寫作思路,以此來作為細(xì)節(jié)判斷的依據(jù)。

        如果能夠?qū)㈩}目定位到某一段,那么就可以用該段的TS(Topic Sentence 主題句)來進(jìn)行排除,和TS無關(guān)的就是正確選項(xiàng)。

        二、舉例說明:

        下面是No.5-2題目中的一道長閱讀,我把它的第一段截取了出來:

        In large part as a consequence of the feminist movement, historians have focused a GREat deal of attention in recent years on determining more accurately the status of women in various periods. Although much has been (5) accomplished for the modern period, premodern cultures have proved more difficult: sources are restricted in eg. number, fragmentary, difficult to interpret, and often contradictory. Thus it is not particularly surprising that some earlier scholarship concerning such cultures (10) has so far gone unchallenged. An example is Johann Bachofen’s 1861 treatise on Amazons, women-ruled societies of questionable existence contemporary with ancient GREece.
