1．Imagine looking for your lost dog．You step into a cave（洞穴）．But instead of the dog，you find beautiful cave paintings．You see paintings of horses，deer，and bison that are drawn in black，brown，red and yellow．Your first question would probably be"Who did this？"
This is what happened to four French boys in 1940．They found the Lascaux caves．The paintings the boys discovered in those caves are 17，000years old．They were drawn by the ancient people called Cro-Magnons．
Cro-Magnons looked much like people of today．They used tools，such as fishing nets．But their art was extremely good．The main cave at Lascaux is called the Great Hall of Bulls，which has a picture of bulls and horses in many colors．The largest animal is 18feet long．There are smaller animals，such as bison，stags（雄鹿） and a bear．There is also a strange spotted two-horned （兩只角的） animal．
To the left of the main cave are the most famous paintings that are the drawings of multicolored animals．One painting is called Little Horses．On the ceiling are horses and cows．The most unusual sight may be in the Shaft of the Dead Man where there is a thinoceros （犀牛），a carefully drawn dead man，a wounded bison and a bird．
Why did Cro-Magnon artists do these beautiful drawings on cave walls？Did the drawings call upon some magical power？Did the Cro-Magnon people hope that the drawings would bring good luck？There is one thing the paintings seem to tell us．The Cro-Magnons were interested in the world．They looked at beauty and they understood it．

分析 本文介紹了法國(guó)Lascaux巖洞壁畫的相關(guān)情況．
解答 21-23：ADC
21 A．推理判斷題．第一段虛構(gòu)了一個(gè)以讀者為主人公的場(chǎng)景，目的就是為了引起讀者的閱讀興趣．故選A．
22 D．細(xì)節(jié)理解題．根據(jù)第三、四段which has a picture of bulls and horses in many colors．對(duì)壁畫的描述可知，洞內(nèi)的絕大多數(shù)壁畫是關(guān)于動(dòng)物的．故選D．
23 C．主旨大意題．文章開頭指出了發(fā)現(xiàn)壁畫的過(guò)程，接下來(lái)的內(nèi)容描述了這些壁畫．只有C項(xiàng)能夠全面概括全文內(nèi)容．A項(xiàng)范圍太廣，且有些偏題； B、D兩項(xiàng)只是文中的細(xì)節(jié)，不能概括全文．故選C．
點(diǎn)評(píng) 學(xué)生需要認(rèn)真閱讀原文，把握文章大意，對(duì)文章脈絡(luò)有整體的了解，能仔細(xì)查找文中細(xì)節(jié)，并能根據(jù)文章內(nèi)容進(jìn)行合理的推測(cè)判斷．
