1、最新GMAT南極臭氧考題GMAT邏輯機(jī)經(jīng)能夠指引人們?cè)陂喿x的道路上不再迷茫，這不GMAT閱讀機(jī)經(jīng)就來(lái)為你指明道路，小編就在這寒冬中為大家吹來(lái)一股GMAT機(jī)經(jīng)的暖風(fēng)，為大家分享GMAT閱讀機(jī)經(jīng)，希望大家能感受到這股暖意，并把它化為能量，在GMAT考試的道路上勇往直前。360教育集團(tuán)介紹，關(guān)于南極地區(qū)的臭氧層變化對(duì)氣候的影響，提到一個(gè)什么winds，然后說(shuō)到南極圈臭氧黑洞在近幾年的逐步恢復(fù)過(guò)程中，對(duì)全球的氣候會(huì)造成一些影響(提到說(shuō)南美洲會(huì)變濕潤(rùn)，這里第一題就問(wèn)這個(gè)，然后澳大利亞會(huì)變枯燥。題目是說(shuō)假設(shè)黑洞恢復(fù)，會(huì)對(duì)全球經(jīng)濟(jì)的至少正面的一些影響，我選的是說(shuō)墨西哥一些枯燥少雨的地方會(huì)受益。剩下的題記不清

2、了)?？脊?補(bǔ)充材料：(確認(rèn))1.2.1 臭氧空間 By huiwaziV1剛想到有篇月度，就是說(shuō)臭氧層空洞，文章前面說(shuō)臭氧層空洞會(huì)曬傷，但是最主要的是說(shuō)空洞和大氣之間的作用力會(huì)導(dǎo)致風(fēng)的改變，從而導(dǎo)致南澳洲的天氣變化。V2 by tompry 760關(guān)于臭氧層空洞的，分兩段，不長(zhǎng)，第一段大致介紹了南極圈上的臭氧層的根本概況。記得有一道題要選擇臭氧的濃度在不同季節(jié)不同第二段講的是空洞進(jìn)一步擴(kuò)大會(huì)造成的后果。這里有到選擇題，我選的是澳大利亞的人會(huì)擔(dān)憂變干的天氣會(huì)造成火災(zāi)。V2是臭氧層的第一段有說(shuō)臭氧層里的某個(gè)物質(zhì)在springtime里low，吸收的紫外線少，所以溫度低(這個(gè)覺(jué)得挺奇怪的)第二段里

3、面說(shuō)這個(gè)臭氧層破壞的影響然后又說(shuō)科學(xué)家發(fā)現(xiàn)臭氧層在recovery，接著預(yù)測(cè)full recovery之后的影響，澳大利亞會(huì)變干，南美會(huì)變濕，對(duì)南半球的風(fēng)有影響(促進(jìn)還是減弱忘了)，南極洲也會(huì)受到影響，這里有except題，V3ozone的，在artantic(拼的不對(duì))上空，不同季節(jié)厚度不一樣，吸收紫外線防曬傷。還有影響澳大利亞，變得更枯燥。v4還有一個(gè)關(guān)于臭氧空洞的。第一段開始說(shuō)臭氧的作用是吸收一個(gè)什么東西的放射，就防止了皮膚癌。然后說(shuō)了每當(dāng)澳大利亞的春季就是9月到12月的時(shí)候臭氧一般都比擬稀薄，這里有題，問(wèn)正常情況下臭氧的特點(diǎn)，我選的就是這個(gè)，每個(gè)季節(jié)臭氧量是不一樣的。第二段說(shuō)現(xiàn)在臭氧層

4、越來(lái)越小了，然后產(chǎn)生了一系列的后果，有一個(gè)后果是change the weather patterns，比方澳大利亞變干了，非洲某個(gè)地方潮濕了，這里也有題，挺簡(jiǎn)單的不記得了。反正就是哪的氣候變了之類的。然后還有一個(gè)問(wèn)題是如果現(xiàn)在政府非常嚴(yán)格的保護(hù)臭氧層，會(huì)有哪些影響，我記得我選的是那些澳大利亞的農(nóng)民不用再擔(dān)憂干旱的危害了。V5一篇是ozone layer 對(duì)Antalantic 氣候的影響。V6第一段說(shuō)北極臭氧層吸收紫外線，有個(gè)空洞，而且說(shuō)在春節(jié)臭氧密度會(huì)不一樣，難后說(shuō)有一個(gè)赤道北極風(fēng)之類的，會(huì)使得北極的氣溫下降(大概也下降，也可能上升，不記得了)，第二段說(shuō)赤道北極風(fēng)會(huì)影響什么什么的天氣，但現(xiàn)

5、在北極的臭氧層洞在被填補(bǔ)，于是那個(gè)赤道北極風(fēng)減少了，而加強(qiáng)了另一個(gè)什么什么風(fēng)的，會(huì)使得北極的氣候轉(zhuǎn)變(第一段如果是下降的話，就是上升，反之亦然)。使得澳大利亞，南美變得干旱好似記得有一道題目說(shuō)如果臭氧層洞繼續(xù)被填補(bǔ)的話，那么誰(shuí)會(huì)得到利益5個(gè)選項(xiàng)記得三個(gè)，順序忘了美國(guó)或者出口糧食給墨西哥的商人 我就選的這個(gè)吧關(guān)注澳大利亞森林野火和火災(zāi)的人南美研究氣象的氣象學(xué)家還有一個(gè)好似是研究北極溫度的人。V7臭氧那個(gè) 完全不一樣 1 考的什么為什么說(shuō)臭氧層和那個(gè)太陽(yáng)的輻射相互作用 定位第一段第一句2 那個(gè)什么風(fēng)的特征神馬的 定位第一段末尾和第二段開頭3 不記得了V8臭氧的那個(gè)寂靜里有點(diǎn)不準(zhǔn)確，臭氧層的修復(fù)導(dǎo)致

6、了澳大利亞枯燥，南美濕潤(rùn)。V9 by fatdudu 640臭氧層。很確定。P1說(shuō)的是臭氧層空洞-溫室效應(yīng)全球變熱，皮膚癌多-但是南極卻相反變冷-南極與其它地區(qū)溫差加大-CIRCUM風(fēng)大。臭氧層恢復(fù)-C風(fēng)小，S風(fēng)大-氣候PATENT變化：南美濕潤(rùn)，澳大利亞變干(最后一題問(wèn)誰(shuí)會(huì)受益于臭氧層恢復(fù)。肯定不選澳洲擔(dān)憂火災(zāi)得人。選的是原來(lái)南美缺少雨的農(nóng)民)這篇大家一定要看狗里給的英文參考文章，重點(diǎn)全說(shuō)到了。V10 by clowncish0625 740Q1：選臭氧層的濃度在不同季節(jié)不同Q2：有exept題的樣子Q3：好似是問(wèn)那個(gè)對(duì)的還是什么(也可能是臭氧空洞恢復(fù)，會(huì)有什影響還是什么的)，原文里說(shuō)到如果

7、臭氧變厚，即臭氧空洞恢復(fù)，一個(gè)地區(qū)會(huì)變濕潤(rùn)答案D選項(xiàng)說(shuō)了那個(gè)地區(qū)缺雨，最后一單詞是rainfall，就選那個(gè)V11 by mingda 770第一段開始說(shuō)臭氧的作用是吸收太陽(yáng)輻射，就防止了皮膚癌。然后說(shuō)了每當(dāng)澳大利亞的春季(那里的春季和我們北半球這里的是反過(guò)來(lái)的)就是9月到12月的時(shí)候臭氧一般都比擬稀薄(這里有題，問(wèn)正常情況下臭氧的特點(diǎn)，我選的就是這個(gè)，每個(gè)季節(jié)臭氧量是不一樣的(正解)。因?yàn)槌粞跸”×怂晕盏淖贤饩€比擬少，臭氧層所吸收的熱量就比擬小，因此往往就會(huì)比擬寒冷。這會(huì)導(dǎo)致一個(gè)極地風(fēng)盛行，阻礙其他的風(fēng)的活動(dòng)，比方溫帶的暖濕氣流就到不了極地了。第二段說(shuō)科學(xué)家發(fā)現(xiàn)臭氧層在recovery，

8、也就是臭氧層空洞由于大自然自動(dòng)調(diào)節(jié)以及人類氟化物排放的減少在修復(fù)。造成的一系列后果是對(duì)上面一段取非：臭氧厚了，吸收的紫外線多了，天氣就熱了，極地風(fēng)被抑制，其他風(fēng)來(lái)了。接著預(yù)測(cè)full recovery之后的影響，澳大利亞會(huì)變干，南美會(huì)變濕，對(duì)南半球的風(fēng)有影響(促進(jìn)還是減弱忘了)，南極洲也會(huì)受到影響(有一個(gè)問(wèn)題問(wèn)的是full recovery 以后誰(shuí)會(huì)得意，答案是南美洲那些飽受旱災(zāi)困擾的農(nóng)民)V12 by weizhui1208 770jj超級(jí)全 根本都考到了有考如果空洞繼續(xù)填補(bǔ)，最大受益者是誰(shuí)丫。Lz選的南美洲那些以前被干旱折磨的農(nóng)民(因?yàn)樵恼f(shuō)了南美會(huì)變wet嘛)有考如果空洞急需填補(bǔ)，會(huì)發(fā)生

9、except。lz選的B還是C來(lái)著，反正帶“humidity那個(gè)選項(xiàng)，其他原文都有吧，當(dāng)時(shí)細(xì)細(xì)看了的V13 by 取巧 740第一段介紹臭氧的作用(不重要)，然后是臭氧的一個(gè)變化，引起一種wind盛行。第二段是說(shuō)這種現(xiàn)象的影響。(有題，問(wèn)第二段的作用，我選的是第二段是對(duì)第一段提出的現(xiàn)象的進(jìn)一步解釋，反正選有 explain 這個(gè)詞的就對(duì)了)但是有一道題，問(wèn)的是如果臭氧恢復(fù)了，會(huì)有什么影響，要求選except 定位第二段。我在A和B當(dāng)中猶豫半天。因?yàn)锳中有一個(gè)什么大陸，B 改變了降水 我最后還是拿不準(zhǔn)。因?yàn)槲恼抡f(shuō)的 澳大利亞變干了，南美變干了。有同學(xué)google到一定背景知識(shí)，大家可以參考下A
