　　8月GMAT機(jī)經(jīng)換庫(kù)了，現(xiàn)在就由小編來(lái)為大家整理八月份的GMAT閱讀機(jī)經(jīng)整理，下面是關(guān)于GMAT閱讀機(jī)經(jīng)的相關(guān)問(wèn)題，分享給大家，希望對(duì)大家有所幫助，文中觀點(diǎn)僅供參考。

　　Ant Mound Question

　　Talks about how the strucutres of an ant mound and why it is such.. Provides two contrasting views that explains why these strucutures exist. Author support the 2nd theory.

　　Q1)According to the first theory 名字忘記了, what is the purpoes of the tunnels?

　　Answer has something to do with air flow

　　Q2) If the passages were sealed, what would happen according to passage?

　　Answer deals with humidity

　　Q3) 暫時(shí)想不起來(lái)，過(guò)會(huì)兒補(bǔ)充

　　V2 by 大大堯

　　土著人在地下建特別的建筑，有復(fù)雜的內(nèi)部結(jié)構(gòu)，兩種不同的理論討論內(nèi)部的溫控，第一種是說(shuō)熱空氣通過(guò)tunnels上升冷卻，再下來(lái)，這樣循環(huán)。第二種是說(shuō)里面是恒溫的，氣體交換是維持內(nèi)部空氣的濕度穩(wěn)定，還有空氣成分穩(wěn)定，這樣里面有一種菌類可以生長(zhǎng)。

　　有道講terminate mound 的function 的

　　P1在某建筑還是nest的地方發(fā)現(xiàn)一個(gè)煙囪一樣的東西，有人說(shuō)他是用來(lái)維持這個(gè)建筑的溫度的

　　第二段反駁，說(shuō)是用來(lái)空氣流通保持humidity CO2等

　　問(wèn)主旨，選的rute一個(gè)然后提出一個(gè)alternative的

　　有道問(wèn)如果這個(gè)tm的passage被sealed了會(huì)怎樣，定位在第二段

　　※往屆考古 已確認(rèn)

　　好像是一種動(dòng)物在巢穴的周圍挖了一系列的小隧道，有一個(gè)人提出這些隧道是為了保持巢穴恒溫，第二段說(shuō)前面的假說(shuō)錯(cuò)誤因?yàn)槌惭](méi)有恒溫，提出了一個(gè)假說(shuō)是為了保持空氣流通，保持一定的濕度

　　V2 by foxwill

　　一種動(dòng)物螞蟻的巢穴，有一個(gè)中心(大概是chamber)，然后還有很多小隧道(形似mound)，連接他們并通往地面高處。第一個(gè)人提出一種理論認(rèn)為，這些小隧道是用來(lái)保持chamber溫度的。巢穴里因?yàn)槲浵伒男玛惔x，溫度會(huì)不斷上升。而被加熱的溫度mound揮發(fā)出去，地面的降低溫度又通過(guò)mouth補(bǔ)充進(jìn)來(lái)，從而保持巢穴溫度不會(huì)太高。

　　然而，第二個(gè)人發(fā)現(xiàn)保持溫度的理論不對(duì)。這些mound的作用是保持空氣流通的。因?yàn)樗l(fā)現(xiàn)這先mound的出口都在地面XX處(有一個(gè)合成詞，什么ground-level啥玩意的，描述這個(gè)地面特點(diǎn)，我理解為高處通風(fēng)處，具體的大家可以在考場(chǎng)上判讀，不要受我誤導(dǎo))。巢穴中的空氣通過(guò)mound排出，新鮮空氣中的氧氣，二氧化碳和其他成分通過(guò)mound補(bǔ)充進(jìn)來(lái)，從而保證了巢穴內(nèi)空氣的流通(前面的同學(xué)說(shuō)這段還提到了濕度，這個(gè)我記不清了，感覺(jué)好象是選項(xiàng)里出現(xiàn)的未定位內(nèi)容，待確定)。

　　然后舉了個(gè)例子，說(shuō)另外一種昆蟲也有類似的巢穴結(jié)構(gòu)，并且因此而具有強(qiáng)大的生命力。如果這種昆蟲沒(méi)有這個(gè)巢穴結(jié)果，他們會(huì)被surpressed，因?yàn)樗麄兊母?jìng)爭(zhēng)對(duì)手生命力比他們更強(qiáng)。

　　題目都不難，找準(zhǔn)定位就好。記得有道比較陰險(xiǎn)的：

　　1)問(wèn)：第一個(gè)人的理論關(guān)于mound的有：1)保持mound和chamber的溫度一致(這是個(gè)陷阱選項(xiàng));(2)使得巢穴內(nèi)空氣與外界交換(這是正確選項(xiàng)，因?yàn)榈谝粋€(gè)人的描述，保持溫度也是通過(guò)氣體交換實(shí)現(xiàn)的)。這題我比較確定我的答案，當(dāng)時(shí)的定位比較清晰。

　　2)然后還有道好像是問(wèn)關(guān)于第三段那個(gè)例子的，說(shuō)例子昆蟲和他的競(jìng)爭(zhēng)對(duì)手咋樣咋樣，這題讀懂我上面說(shuō)的應(yīng)該就夠了，忘記具體問(wèn)啥了。

　　3)好像還有一道(不太確定)是問(wèn)第一個(gè)人和第二個(gè)人理論的共通點(diǎn)?有這題的話肯定選都是氣體交換了，很明顯。

　　4)然后好像還有一題是針對(duì)地面XX處那個(gè)合成詞的，把這個(gè)詞理解好了就能解題了。具體問(wèn)什么實(shí)在想不起來(lái)，有別的同學(xué)給提示一下的估計(jì)能想起來(lái)，呵呵。

　　v3 by gloria6113 Host age is one of the keyfactors in host–parasite relationships as it possibly affects infestationlevels, parasite-induced mortality of a host, and parasite distribution amonghost individuals. We tested two alternative hypotheses about infestationpattern and survival under parasitism in relation to host age. The first hypothesisassumes that parasites are recruited faster than they die and, thus, suggeststhat adult hosts will show higher infestation levels than juveniles because thormer have more time to accumulate parasites. The second hypothesis assumesthat parasites die faster than they are recruited and, thus, suggests thatadults will show lower infestation levels because of acquired immune responseand/or the mortality of heavily infested juveniles and, thus, selection forless infested adults. As the negative fects of parasites on host are oftenintensity-dependent, we expected that the age-related differences ininfestation may be translated to lower or higher survival under parasitism ofadults, in the cases of the first and the second hypotheses, respectively. Wemanipulated ectoparasite numbers using insecticide and assessed the infestationpattern in adult and juvenile gerbils (Gerbillus andersoni) in the Negev Desert.We found only a partial support for age-dependent parasitism. No age-relateddifferences in infestation and distribution among host individuals were foundafter adjusting the ectoparasite numbers to the host’s surface area. However,age-related differences in survival under parasitism were revealed. Thesurvival probability of parasitized juveniles decreased in about 48% comparedto unparasitized hosts while the survival probability of adults was notaffected by ectoparasites. Our results suggest that the fect of host age onhost–parasite dynamics may not explicitly be determined by age-dependentdifferences in ectoparasite recruitment or mortality processes but may also beaffected by other host-related and parasite-related traits

　　是那個(gè)蟻穴 降溫還是通風(fēng)的。問(wèn)題有一個(gè)是問(wèn)2個(gè)理論的共同點(diǎn) 2. 第一個(gè)觀點(diǎn)認(rèn)為下面那個(gè)是對(duì)的

　　V5 by wang_mm2000

　　寄生那篇文章，所google到的部分其實(shí)只是考試文章的第一段，后面還有很重要的一段沒(méi)有。而且有三道細(xì)節(jié)題出在第二段，其中有一道問(wèn)如果adult and juvenile have the same surface area ,which of followingwill be true? 還有一道問(wèn)soil erosion,請(qǐng)大家定位文章的最后一句話， 我就是沒(méi)注意這個(gè)詞，結(jié)果浪費(fèi)了不少時(shí)間去找。汗。

　　以上就是對(duì)于8月GMAT閱讀機(jī)經(jīng)的相關(guān)介紹，希望對(duì)大家備考GMAT考試有所幫助，文中觀點(diǎn)僅供參考。
