Task 3The difficulties that would have to be encountered by anyone who attempted to explore the Moon would be incomparably greater than those that have to be faced in the endeavor to reach the summit of Mount Jolmo Lungma. In two respects only would the lunar explorer have the advantage. In the first place movement would be less fatiguing because the gravitational pull of the Moon is not very great, the weight of the Moon being only about one - eightieth of that of the Earth. If the Moon had an atmosphere like that of the Earth, a man playing golf on the Moon would find that he could drive his ball for a mile without much difficulty.

They were brilliant students of Greek geometry and trigonometry, and they applied their knowledge to the constructions of fine bridges, roads, aqueducts, and public buildings.They knew about the smelting of iron ore, but they used the iron they produced mainly for spears, swords, and shields, rather than for building construction.While the Romans accomplished practical wonders, they did very little theoretical scientific thinking. Because of their frequent wars, many of their inventions were no more than improvements in the design of Greek weapons with which they were familiar.There are two reasons for the Romans neglect of philosophy and pure mathematics. First, they were apparently too busy conquering nearby nations and forming them into a rapidly growing empire to waste much time on abstract thinking. Secondly, they were handicapped by the rigidity of their numerical system. The Romans did all of their arithmetic on an abacus, the ancient counterpart of the modem computing machine. Their number system discouraged the study of pure mathematics. Which is mentioned as the reason for which many Roman inventions were based on Greek weapons（）
