A group of students (S) from England has come to the Zhoukoudian caves for a visit.An archaeologist (A) is showing them round.
A:Welcome to the Zhoukoudian caves here in China.It is a great pleasure to meet you students from England,who are interested in archaeology.You must be aware that it's here that we found evidence of some of the earliest people who lived in this part of the world.We've been excavating here for many years and ...
S1:I'm sorry to interrupt you but how could they live here?There are only rocks and trees.
A:Good question.You are an acute observer.We have found human and animal bones in those caves higher up the hill as well as tools and other objects.So we think it is reasonable to assume they lived in these caves,regardless of the cold.
S2:How did they keep warm?They couldn't have mats,blankets or quilts like we do.It must have been very uncomfortable.
A:We've discovered fireplaces in the centre of the caves where they made fires.That would have kept them warm,cooked the food and scared wild beasts away as well.We have been excavating layers of ash almost six metres thick,which suggests that they might have kept the fire burning all winter.We haven't found any doors but we think they might have hung animal skins at the cave mouth to keep out the cold during the freezing winter.
S3:What wild animals were there all that time ago?
A:Well,we've been finding the bones of tigers and bears in the caves,and we think these were their most dangerous enemies.Now what do you think this tells us about the life of these early people?(shows picture of a sewing needle)
S2.:Gosh!That's a needle.Goodness,does that mean they repaired things?
A:What else do you think it might have been used for?
S4:Let me look at it.It's at most three centimetres long.Ah yes,it seems to be made of bone.I wonder how they made the hole for the ...
S2:(interrupting) Do you mean that they made their own clothes?Where did they get the material?
A:They didn't have material like we have today.Can you guess what they used?
Sl:Wow!Did they wear clothes made entirely of animal skins?How did they prepare them?I'm sure they were quite heavy to cut and sew together.
A:Our evidence suggests that they did wear clothes made from animal skins.We continue discovering tools that were sharpeners for other tools.It seems that they used the sharpened stone tools to cut up animals and remove their skin.Then smaller scrapers were probably used to remove the fat and meat from the skin.After that they would rub an ample amount of salt onto the skin to make it soft.Finally,they would cut it and sew the pieces together.Quite a difficult and messy task!Now look at this.(shows a necklace)
S2:Why,it's a primitive necklace.Did early people really care about their appearance like we do?It's lovely!
A:Yes,and so well preserved.What do you think it's made of?

一群英国学生（学）来到周口店洞穴参观.有一位考古学家（考）正领着他们参观.
考：欢迎到中国来参观周口店洞穴.很高兴见到你们这些从英国来的对考古学感兴趣的学生.你们想必都很清楚,正是在这个地方,我们找到了世界上居住在这个地方最早人类的证据.我们在这儿进行的挖掘工作已经很多年了,而且……
学1：
对不起,打断一下你的讲话,请问他们是怎么住在这个地方的呢?这儿只有石头和树木.考：问得好.你是个敏锐的观察者,在高山上的那些洞穴里我们找到了人骨和兽骨,还有工具和其他物品因此,我们有理由认为他们不顾严寒,就住在这些洞穴里.
学2：那他们是怎样取暖的呢?他们不可能像我们现在这样有垫子、毯子和被子.想必是很不舒服的了.
考：我们发现在洞穴中央有生火用的地炉.他们用地炉里的火来取暖、做饭,还可以用火来吓跑野兽.我们一直在挖掘一层层的积灰,几乎有六米厚,这意味着他们可能整个冬天都在烧火.我们还没有找到门,但我们认为在天寒地冻的冬季他们可能是用兽皮挂在洞口来防寒的.
学3：在那以前有些什么野兽吗?考：嗯,我们在洞里发现了老虎和熊的骨头.我们认为这些野兽对他们来讲是最危险的敌人了.现在,你们看这个东西能告诉我们有关早期人类生活的什么情况呢?（指着一张有针线的照片让大家看）
学2：哎呀,那是一根针!天哪,难道他们还会修补东西吗?
考：除此之外,你认为还可能派别的什么用场吗?
学4：让我看看.这个东西最多三厘米长,看起来像是用骨头做的.我不知道他们是怎样做成针眼的……
学2：（插话）你是不是说他们自己做衣服穿?他们又是从哪里得到衣料的呢?
考：他们没有像我们今天穿的这种衣料.你能猜出他们用的是什么吗?
学1：哇,他们穿的衣服全都是用兽皮做的吗?他们那些衣服是怎样做成的?我确信它们裁剪并缝起来又厚又重.
考：我们有证据表明,他们的确穿的是用兽皮制的衣服.我们不断发现一些磨削其他工具用的工具.看样子他们可能是用磨尖的石器来切割野兽并剥皮,再用小一些的刮子把皮上的脂肪和肉去掉.然后,他们可能在兽皮上擦上大量的盐,使皮变柔软.最后进行剪裁,缝起来就成了.确实是既难又脏的活!现在来看看这个吧.（指着一串项链）
考：你真聪明!有块骨头实际上是野兽的牙齿,贝壳是从海边捡来的.你还认得别的骨头吗?
学1：这根很像鱼骨头,对吗?
考：很对.植物学的分析结果明确地告诉我们,这儿四周曾经是一个很．大的浅水湖.毫无疑问,当时湖里是有鱼的.
学3：不过,湖并不是海呀,我们离海还远着呢¨眷客,更壳又是怎么来的呢?
考：早期人类之间也许有贸易来往,或者他们也可能旅行到海边去.我们知道,他们跟着兽群四处走.他们并不种植谷物,而是在野果熟了的时候采摘它们并捕杀野兽来充饥.这就是他们被称之为猎人和采摘者的缘故.现在,咱们去参观洞穴好吗?
