Science, as we think, was born when the Greek philosopher ( 希腊哲学家 ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe?
No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance ( 物质 ) of the universe.
Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe.
The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more plicated than the Greeks realized. We now know of 103 basic substances which we call “ elements ( 元素 )”.

解析：本文讲述的是科学起源的话题，古希腊思想家Thales提出了宇宙是由什么组成的时候？科学就出现了。并讲述了希腊人对这个问题的研究。
【小题1】B 计算题。根据文章第一行( about 640-546 B.C.)可知他大约94岁，所以是在94岁的时候去世的。故B正确。
【小题2】C 推理题。根据文章第一段Science, as we think, was born when the Greek philosopher ( 希腊哲学家 ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe?可知在古希腊的时候，Thales提出了这个问题，科学就出现了。故C正确。
【小题3】D 细节题。根据文章3,4段Other Greek thinkers became interested in this question.和The Greek philosophers were feeling their way towards the ideas on which chemistry is based.
