Question

16．Near the town of Montignac in Southern France，visitors can find some of the most beautiful cave paintings in the world-the Lascaux Cave Paintings（拉斯科洞窟壁画）．
    The history of these paintings is very interesting．Most caves are formed（61）bynature under the ground，but some have entrances people can find．That's just what happened one day in 1940．Four boys were taking（62）awalk in the woods near Montignac．As they walked along，one of them noticed an unusual rock．（63）Whenthey got closer，they found it wasn't a rock but an opening in the ground．This opening led to a cave，so they decided to have a look around it．The walls of the cave were（64）covered（cover）with ancient art．The boys didn't know it，but the cave was the find of the century!
    Over the years，many historians and artists came to study the art．They wanted to understand who painted the pictures and（65）whatthey might mean．They soon realized some of the art indicated animals that were on Earth a long time ago．Many of the pictures also showed people（66）following（follow）animals and trying to kill them for food．In the end，historians agreed that this was likely to be the art of a civilization that existed over 15，000 years ago．
    By 1950，over a thousand people from all over the world were visiting the cave every day．But by 1955，the paintings were beginning to become difficult（67）to see（see）．Many people were passing through the cave，so the paintings were losing their color．（68）Sadly（sad），people can no longer visit the cave．However，another set of cave paintings has been created．These paintings look exactly the same（69）asthe Lascaux Cave Paintings．People （70）made（make）the paintings so that everyone can still learn about this great ancient civilization．

Answer 1

分析 本文主要讲述法国南部蒙提涅克镇，游客可以看到的一些世界上最美丽的洞穴绘画--拉斯科洞窟壁画的有趣的历史．文章讲述了壁画是如何被四个男孩偶然发现的，许多历史学家和艺术家来学习壁画的艺术，他们想了解谁画的画以及壁画的意义，因为参观的人数很多，所以画失去了他们的颜色，到1955年这些画开始很难见到了．人们创建了另一套和拉斯科洞窟壁画几乎一样的洞穴壁画，让每个人都能了解这个伟大的古老文明．

解答 61．by 考查介词的用法． 分析句意可知，该句的意思是：大多数洞穴是在地下自然形成的；此处是被动语态，需要介词by引出动作的发出者；故填by．
62．a  考查固定短语的用法．  固定短语take a walk 意为：散步；故填a．
63．When  考查连词的用法． 本句的意思应是：当他们靠近些时，他们发现那不是一块石头，而是一个留在地面上的开口；故填When意为"当…的时候"． 
64．covered  考查固定短语的用法． 固定短语be covered with 被…覆盖着；本句的意思是：洞穴的墙上布满了古代的绘画；故填covered．
65．what  考查疑问代词的用法． 本句是宾语从句，and之前的意思是：谁画的图画，之后应为：画了些什么；故填疑问代词what．
66．following 考查现在分词的用法． 分析句意可知，这里展现的应是人们在追逐动物并试图要杀了他们作食物的画面；动词follow与其逻辑主语people构成主谓关系，表示当时正在进行的动作，应用动词的现在分词形式，故填following．
67．to see  考查动词不定式的用法．动词不定式与句子的主语构成逻辑上的动宾关系，所以用动词不定式的主动形式表被动，故填to see．
68．Sadly 考查副词的用法．根据句子可知，此处是副词修饰后面的整个句子，故填Sadly．
69．as 考查固定搭配的用法．the same as是固定搭配，意为"和…一样"，故填as．
70．mdae 考查一般过去时态的用法．根据前面的"another set of cave paintings has been created．"另一套洞穴壁画已被创建，可知人们制作壁画是在过去，是一个过去的动作，所以用一般过去时态，故填made．
