listen to the material carefully,although it is difficult and sometime you can't write down the correct answer.As long as you have tried,whatever you write down will be the harvest of yours.You should believe that only by accumulating little by little could you learn English welll.so come on.
Future historians will be in a unique position when they come to record the history of our own times. (1)_______________________. What is more, they will not have to rely solely on the written word. Films, videos, CDs and CD-ROMS are just some of the bewildering amount of information they will have. They will be able, as it were, to see and hear us in action. But the historian attempting to reconstruct the distant past is always faced with a difficult task. He has to deduce what he can from the few scanty clues available. Even seemingly insignificant remains can shed interesting light on the history of early man.
(2)_______________________. Recent scientific evidence seems to indicate that this assumption is incorrect.
Historians have long been puzzled by dots, lines and symbols which have been engraved on walls, bones, and the ivory tusks of mammoths. The nomads who made these markings lived by hunting and fishing during the last Ice Age which began about 35,000 B.C. and ended about 10,000 B.C. (3)_______________________. They have found that it is connected with the passage of days and the phases of the moon. It is, in fact, a primitive type of calendar. It has long been known that the hunting scenes depicted on walls were not simply a form of artistic expression. They had a definite meaning, for they were as near as early man could get to writing. It is possible that there is a definite relation between these paintings and the markings that sometimes accompany them. It seems that man was making a real effort to understand the seasons 20,000 years earlier than has been supposed.
They will hardly know which facts to select from the great mass of evidence, they steadily accumulate
Up to now historians have assumed that calender is came into being with the advent of agriculture, for then men was faced with real need to understand something about the seasons
By callading markings made in every parts of the world, historians have been able to read this difficult code
