托福閱讀原文

【1】The Sahara is a highly diverse, albeit dry, region that has undergone major climatic changes since 10,000 B.C. As recently as 6,000 B.C. the southern frontier of the desert was far to the north of where it is now, while semiarid grassland and shallow freshwater lakes covered much of what are now arid plains. This was a landscape where antelope of all kinds abounded—along with Bos primigenius, a kind of oxen that has become extinct. The areas that are now desert were, like all arid regions, very susceptible to cycles of higher and lower levels of rainfall, resulting in major, sudden changes in distributions of plants and animals. The people who hunted the sparse desert animals responded to drought by managing the wild resources they hunted and gathered, especially wild oxen, which had to have regular water supplies to survive.

【2】Even before the drought, the Sahara was never well watered. Both humans and animals were constantly on the move, in search of food and reliable water supplies. Under these circumstances, archaeologist Andrew Smith believes, the small herds of Bos primigenius in the desert became smaller, more closely knit breeding units as the drought took hold. The beasts were more disciplined, so that it was easier for hunters to predict their habits, and capture animals at will. At the same time, both cattle and humans were more confined in their movements, staying much closer to permanent water supplies for long periods of time. As a result, cattle and humans came into close association.

【3】Smith believes that the hunters were well aware of the more disciplined ways in which their prey behaved. Instead of following the cattle on their annual migrations, the hunters began to prevent the herd from moving from one spot to another. At first, they controlled the movement of the herd while ensuring continuance of their meat diet. But soon they also gained genetic control of the animals, which led to rapid physical changes in the herd. South African farmers who maintain herds of wild eland (large African antelopes with short, twisted horns) report that the offspring soon diminish in size, unless wild bulls are introduced constantly from outside. The same effects of inbreeding may have occurred in controlled cattle populations, with some additional, and perhaps unrecognized, advantages. The newly domesticated animals behaved better, were easier to control, and may have enjoyed a higher birth rate, which in turn yielded greater milk supplies. We know from rock paintings deep in the Sahara that the herders were soon selecting breeding animals to produce offspring with different horn shapes and hide colors.

【4】It is still unclear whether domesticated cattle were tamed independently in northern Africa or introduced to the continent from southwest Asia. Whatever the source of the original tamed herds might have been, it seems entirely likely that much the same process of juxtaposition (living side by side) and control occurred in both southwest Asia and northern Africa, and even in Europe, among peoples who had an intimate knowledge of the behavior of wild cattle. The experiments with domestication probably occurred in many places, as people living in ever-drier environments cast around for more predictable food supplies.

【5】The cattle herders had only a few possessions: unsophisticated pots and polished adzes. They also hunted with bow and arrow. The Saharan people left a remarkable record of their lives painted on the walls of caves deep in the desert. Their artistic endeavors have been preserved in paintings of wild animals, cattle, goats, humans, and scenes of daily life that extend back perhaps to 5,000 B.C.. The widespread distribution of pastoral sites of this period suggests that the Saharans ranged their herds over widely separated summer and winter grazing grounds.

【6】About 3,500 B.C., climatic conditions again deteriorated. The Sahara slowly became drier and lakes vanished. On the other hand, rainfall increased in the interior of western Africa, and the northern limit of the tsetse fly, an insect fatal to cattle, moved south. So the herders shifted south, following the major river systems into savanna regions. By this time, the Saharan people were probably using domestic crops, experimenting with such summer rainfall crops as sorghum and millet as they move out of areas where they could grow wheat, barley, and other Mediterranean crops.

[Glossary]

adzes: cutting tools with blades set at right angles to the handle.

托福閱讀答案

1.原文寫到"在公元前六千年左右，在沙漠的南邊界，遠(yuǎn)離北邊的地方現(xiàn)在是干旱的平原，當(dāng)時(shí)這里是各種羚羊和原始牛都很豐富的山水畫般的地方"那么也就是說(shuō)那時(shí)候那個(gè)地方還不是沙漠。所以A，當(dāng)時(shí)沙漠要比現(xiàn)在少，正確。B現(xiàn)在沒(méi)grassland。C并沒(méi)說(shuō)這個(gè)改變是在公元前6000年發(fā)生的。D通過(guò)"along with"可以知道這兩種動(dòng)物是生活在一起的。

2.通過(guò)原文albeit前后兩個(gè)詞可以推出轉(zhuǎn)折意義，前面是多樣性的，后面是干燥的，兩者有褒貶對(duì)比，所以選C

3.根據(jù)all arid region定位(紅色標(biāo)出句)選項(xiàng)A錯(cuò)誤，原文沒(méi)說(shuō)。B，原文雖然提到了distribution of plants，但是并沒(méi)說(shuō)所有的干燥地區(qū)這一點(diǎn)都是相似的。C正確，原文說(shuō)very susceptible to higher and lower levels of rainfall。D錯(cuò)誤，最后一句說(shuō)人們因此而開始manage resources。

4.對(duì)應(yīng)文章地三句，第四句。根據(jù)原文說(shuō)這種牛群體更小了，繁殖的單位更小，別馴化了，跟容易被預(yù)測(cè)。所以B，D錯(cuò)誤，C原文沒(méi)提到，只說(shuō)其群體變小。也就是A。

5.根據(jù)close association定位到最后一句，但這句說(shuō)as a result，那么原因就在前面一句。前一句說(shuō)cattle human都staying much closer to permanent water supplies。所以完美的對(duì)應(yīng)了B。

6.這個(gè)例子之前一直在說(shuō)herders gained genetic control和其影響。然后給出這個(gè)例子，后面的內(nèi)容也在說(shuō)放牧人是怎樣進(jìn)行基因控制的。所以應(yīng)該選B。

7.根據(jù)domesticated animals 定位到這一段后半部分，已用紅色字標(biāo)出，加粗字體為domesticated animals的描述。D沒(méi)提到。所以選D。

8.這里的主干內(nèi)容是，不管馴化動(dòng)物從哪起源的，最后在不同的地區(qū)得到的都是同樣的方法：juxtaposition，control。根據(jù)以上信息對(duì)選項(xiàng)進(jìn)行排除。

A：前半句沒(méi)問(wèn)題。后半句和原文關(guān)系不符

B：正確，包括了所有主干部分。

C：完全和原文說(shuō)的不是一回事兒啊。

D：原文并沒(méi)有因果關(guān)系。

9.A對(duì)應(yīng)第一句，除了牛，他們還有住所和斧頭。C對(duì)應(yīng)最后一句。D對(duì)應(yīng)第三句。B，原文雖然說(shuō)到他們?cè)谏衬钐幍亩囱ɡ锂嫯嬃?，但是沒(méi)說(shuō)他們住那。所以不對(duì)，選B。

10.Endeavor是努力，盡力的意思。A是方法;B風(fēng)格;C景象;D努力。所以D最貼切。從文章可以推測(cè)。之前在描述他們的生活場(chǎng)景，財(cái)產(chǎn)，打獵。然后說(shuō)他們畫畫。這里問(wèn)的是記錄了什么，那么應(yīng)該是他們之前做出的努力。別的單詞帶入后都解釋不通。

11.通過(guò)這個(gè)詞后面的一句話對(duì)撒哈拉的描寫可以看出都是負(fù)面發(fā)展。更干燥，湖也消失了。A是不穩(wěn)定，B是困苦，C是完全改變。

12.根據(jù)move south和savanna region定位到原文字體標(biāo)注處，這句話開頭出現(xiàn)So，那證明往前一句就是原因。前一句說(shuō)西部降水變多了，并且northern limit of the tsetse fly moved south，所以牛群也move south。對(duì)應(yīng)了C選項(xiàng)。D可能是個(gè)迷惑選項(xiàng)，但是按原文的意思，river只是牛遷徙的路徑"following"，但并不是原因。

13.需要插入的句子說(shuō)"這個(gè)知識(shí)使得獵人改變了打獵的方法"。那么前面應(yīng)該說(shuō)獵人得到了什么知識(shí)，后面應(yīng)該說(shuō)這個(gè)方法怎么改變了。A選項(xiàng)完美符合了這個(gè)邏輯和內(nèi)容。

提供者：請(qǐng)選擇

14.A錯(cuò)誤，原文說(shuō)因?yàn)楦珊?，所以農(nóng)民開始manage the resources。對(duì)應(yīng)原文第一段最后一句。B錯(cuò)誤，原文說(shuō)因?yàn)楦珊?，所以農(nóng)民開始manage the resources。對(duì)應(yīng)原文第一段最后一句。C正確。對(duì)應(yīng)原文第三段。D前半句正確，但后半句不對(duì)，在他們選中種畜之后，已經(jīng)明確的知道了好處。E雖然這句內(nèi)容文章都有提到，但是并沒(méi)有although這樣的邏輯變化。所以不選。F正確。對(duì)應(yīng)文章最后一段。

托福閱讀譯文

【1】盡管干旱，撒哈拉的物種極其多樣，并自公元前10,000年前開始已經(jīng)歷了數(shù)次重大氣候變遷。直到公元前6,000年前，沙漠的南部邊界比現(xiàn)在的位置要靠北很多，那時(shí)半干旱的草原和淺淡水湖泊覆蓋了現(xiàn)在干旱的平原。這里曾經(jīng)是各種羚羊和一種已滅絕的野牛出沒(méi)的地方?，F(xiàn)在的沙漠地區(qū)，像所有干旱地區(qū)一樣，對(duì)降雨量的變化周期極為敏感，因而其動(dòng)植物的分布變化巨大且迅速。依靠捕食稀少的沙漠動(dòng)物的居民對(duì)待干旱的方式是管理他們捕捉和收集到的野生資源，尤其是需要可靠水源維持生命的野牛。

【2】甚至在干旱之前，撒哈拉地區(qū)也從未有充足的水分。人類和野生動(dòng)物都不停的遷徙，以尋找食物和可靠的水源。在這些情況下，考古學(xué)家Andrew Smith 認(rèn)為隨著干旱的持續(xù)，沙漠中野牛群會(huì)變成更小，組織更緊密的族群。獸群變得更加自律，因此獵人更容易預(yù)測(cè)他們的習(xí)性并隨意抓捕。同時(shí)，駱駝和人類的行動(dòng)范圍進(jìn)一步靠近，在固定水源附近長(zhǎng)期更親近的共處。結(jié)果駱駝和人類形成了緊密的聯(lián)合。

【3】Smith相信獵人對(duì)獵物更加自律的行為了然于胸。獵人們不再跟隨駱駝進(jìn)行每年一度的遷徙而是開始阻止獸群的遷移。起初他們控制獸群的遷移以獲得持續(xù)的肉食來(lái)源。但很快他們能夠在遺傳上控制動(dòng)物，使得獸群的體征迅速變化。南非牧養(yǎng)大羚羊(一種體型較大的非洲羚羊，它們的角短且扭曲)的農(nóng)民說(shuō)如果不持續(xù)從野外引進(jìn)公羚羊則其后代體型迅速變小。近親繁殖的影響同樣發(fā)生在控制擁有某些額外的可能并未認(rèn)清的優(yōu)勢(shì)的駱駝數(shù)量上。最新馴化的動(dòng)物更易控制，出生率也更高，而反過(guò)來(lái)也會(huì)提供更多奶源。我們從撒哈拉腹地的巖石繪畫可知牧民很快就選擇一些動(dòng)物進(jìn)行繁殖以產(chǎn)生角和顏色不同的后代。

【4】我們?nèi)詿o(wú)法知道駱駝是在北非獨(dú)立馴化的還是從東南亞引入的。不管馴化的獸群起源何處，東南亞和北非，甚至是歐洲的那些對(duì)野生駱駝的行為了然于胸的人們都可能經(jīng)過(guò)了同樣的和他們要馴化的動(dòng)物毗鄰而居并逐漸控制它們的過(guò)程。隨著人們居住環(huán)境不斷干燥和食物供給的可預(yù)測(cè)性更強(qiáng)，馴化的嘗試很可能發(fā)生在很多地方。

【5】駱駝牧養(yǎng)人的財(cái)產(chǎn)很少：一些并不精致的罐子和磨光的斧子。他們也利用弓箭捕獵。撒哈拉人在撒哈拉腹地洞穴的墻壁上留下了很重要的關(guān)于他們生活的記錄。他們的藝術(shù)創(chuàng)作保存了大量關(guān)于野生動(dòng)物、駱駝、山羊、人類及其日常生活的各種場(chǎng)景的繪畫。這些場(chǎng)景可能追溯到公元前5,000年前。這一時(shí)期田園畫古跡的廣泛分布表明撒哈拉人曾在廣泛且獨(dú)立的牧場(chǎng)上放牧。

【6】大約公元前3,500年前，氣候條件又一次惡化。撒哈拉沙漠漸漸地更加干旱，湖泊相繼干涸。另外西非內(nèi)陸降雨增加，并且舌蠅，一種對(duì)駱駝致命的昆蟲，的種群的北部邊界向南移動(dòng)。所以駱駝牧民也追隨大平原區(qū)域的主要河流系統(tǒng)向南遷徙。此時(shí)，隨著撒哈拉人從原本可以種植小麥、大麥和其它一些地中海農(nóng)作物的區(qū)域中遷出，他們可能依靠當(dāng)?shù)氐霓r(nóng)作物，例如像高粱和小米一類的依靠夏季降雨的作物。
