Let me warn you against a mistake that historians of science often make. They sometimes assume that people in the past use the same concepts we do. Here is a wonderful example that makes the use of history of mathematics some while ago. It concerns an ancient Mesopotamian tablet that has some calculations on it using square numbers. The calculations look an awful one like the calculations of the link of the sides of triangle. So that’s what many historians assume they were. But using square numbers to do this is a very sophisticated technique. If the Mesopotamians knew how to do it, as historians started thinking that they did. Well, they learn math with incredibly advanced. Well, it turns out the idea of Mesopotamians use square numbers to calculate the link of triangle’ s sides is probably wrong. Why? Because we discovered that Mesopotamians didn’t know how to measure angles, which is a crucial element in the whole process of triangle calculations. Apparently the Mesopotamians had a number of other uses for square numbers.
These other uses were important but they were not used with triangles. And so these tablets in all likelihood were practice sheets, if you like, for doing simpler math exercises with square numbers. In all likelihood, it was the ancient Greeks who first calculate the link of triangle’s sides using square numbers. And this was hundreds of years after the Mesopotamians.
Now listen to the following recording and answer questions 23 to 25.
23. According to the professor, what did some historians mistakenly assumed about the Mesopotamians?
24. What was on the Mesopotamian tablet mentioned in the talk?
25. What does the professor imply about the ancient Greeks?
选项
A、They taught the Mesopotamians about square numbers.
B、They were less advanced in mathematics than the Mesopotamians.
C、They did not use square numbers.
D、They knew how to measure angles.
答案
D
解析
推断题。根据Because we discovered that Mesopotamians didn’t know how to measure angles,which is a crucial element in the whole process of triangle calculations.和In all likelihood,it was the ancient Greeks who first calculate the link of triangle’s sides using square numbers.And this was hundreds of years after the Mesopotamians可知.三角形运算过程的关键因素是要知道如何量角,古希腊人十分有可能是第一个运用平方数计算三角形边长关系的。由此推断古希腊人知道如何量角。因此,正确答案是D。
