Vitamins, like minerals, are chemicals. There
is absolutely not difference in the chemical structure 【S1】______
of the nature vitamin C and the chemical structure 【S2】______
of the synthetic vitamin C. Also, while most
substances are harmless at very low level of intake 【S3】______

essential to life—can be dangerous if you overdo
them. Take water for example. Six or eight glasses
a day will keep your body in good fluid balance.

vary greatly in their need for nutrients, it can 【S6】______
necessarily be stated that any given amount is too

The First Calendar
Future historians will be in a unique position when they come to record the history of our own times．They will hardly know which facts to select from the great mass of evidence that steadily accumulates．What is more, they will not have to rely solely on the written word．Films, gramophone records, and magnetic tapes will provide them with a bewildering amount of information．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 and remains that can shed interesting light on the history of early man.
Up to now, historians have assumed that calendars came into being with the advent of agriculture, for then man was faced with a real need to understand something about the seasons．Recent scientific evidence seems to indicate that this assumption is incorrect.
Historians have long been puzzled by dots, lines and symbols that have been engraved on walls, bones, and 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, By correlating markings made in various parts of the world, historians have been able to read this difficult code．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 thereis 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.
第 41 题 In assuming that calendars came into being with the advent of agriculture, historians made the mistake of_____.
A．relying solely on the written word
B．disregarding the markings that early man had been responsible for
C．supposing that nomadic man had no reason to understand the seasons
D．not connecting the passage of days with the phases of the moon
