Born in Italy, Galileo Galilei, was a Tuscan astronomer, philosopher, and physicist. He is closely associated with the 36     (science) revolution. For his great achievements, he has been referred to as the “father of modern astronomy”, as the “father of modern physics”, and as “father of science”. The work of Galileo 37         (consider) to be a significant break from that of Aristotle. In addition, his conflict with the Roman Catholic Church is taken as 38     major early example of the conflict of authority and freedom of thought, particularly with science, 39      Western society. He was a man 40      experimented—never did he take anything for granted. Instead, he despised（蔑视） the prejudices and book learning of the Aristotelians and drew his 41      (conclude) fearlessly. He had been the first 42     (turn) a telescope to the sky, and he had seen there evidence enough to overthrow（推翻） Aristotle and Ptolemy together. Although Galileo found 43       difficult for him to make people 44      (convince) of his theories, he still stuck to his views. His observations showed the theory that the earth moves around the sun was right. It was only many years later 45     the world recognized his greatness.
