3.The herds of bulls and horses depicted running along the walls of the Lascaux caves in France are among the most magnificent examples of prehistoric art ever discovered.
But rather than displaying hunting scenes,new evidence suggests that the images actually represent the frightening sounds which came from the mouths of the caves.
US researcher Steven Waller believes that the echoes(回声) of clapping outside the cave would have sounded like hundreds of animal feet drumming on the ground.He proposes that the caves were preserved for their sound properties,which prehistoric peoples mistook for supernatural noises.
Ancient stories explained echoes from the mouths of certain giant caves as replies from spirits,so our ancestors chose to decorate these caves with paintings believing that they were inhabited by spirits and gods.
Beside animal sounds,many ancient cultures attributed thunder in the sky to‘thunder gods,'so it makes sense that some lasting echoes within the caves were interpreted as thunder and inspired paintings of those thunder gods on cave walls.
The idea is also supported by audio theory,which shows statistically significant similarities between the rock are sites and modern sound reflection equipment.
As for the presence of the famous Stonehenge(巨石阵) in Britain,Mr.Walker also suggests it may have been the sound of the prehistoric monument,rather than the sight,that inspired its creation.
He claims that its architects may have been trying to recreate a sound-effect similar to the ritual sound made during religious dancing.
People taking part in a religious dance around a pair of pipes would have heard the music grow quieter as they moved past certain pipes due to a natural phenomenon known as an‘interference pattern.'If they were blindfold,it would have created the illusion that the sound was intermittently being reduced by invisible gods as they danced.According to Dr.Walker,the effects became so impressive that ancient people attempted to capture it in store.Therefore the Stonehenge appeared.
However some British experts said that it was clear that Stonehenge had been created over several centuries rather than being‘thrown up overnight.'
They claimed that there was no question in the traditional view that lining up along the mid-summer sunrise and mid-winter sunset was the ultimate purpose for its building.
(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

I still remember I helped one of my classmates with his English when we were in the first term of Junior Eight.Li Hua,one of my classmates,was not good at English while I did well.One day,he asked me to help him.So from then on,whenever he had problems,he would ask me,and I was patient to explain them to him.Slowly,his English improved with my help.At the same time,I found my English improved too.
When my family moved,I had to go to a new school and study in a new class.The first test made me so nervous that I failed.I got worried and felt helpless until one of my new classmates came up t o me and asked softly if I was OK.After I told him about my problem,he gave me some advice.From then on,we got to know each other and shared our ideas,problems,and happiness.We became good friends.Sharing with friends helped me bring back my confidence and fit in with (与…和睦相处)others.
In our daily life,we will meet with a lot of trouble.So it is necessary for us to help those who are in trouble.Actually,helping others is helping ourselves.As the saying goes,roses given,fragrance in hand.(正如谚语所说,赠人玫瑰,手有余香.).
