UNIT 1 PEOPLE OF ACHIEVEMENT The fundamental spirit of science lies in seeking truth. 科学的根本精神在于追求真理。 人与社会——有突出贡献的人物 单元主题语境 A Journey of Discovery The captain of the ship，the Beagle，wanted someone who would “profit by the opportunity of visiting distant countries yet little known”.The person who answered the call was not the captain’s first choice. It was a young man who had left medical school without completing his degree. What’s more，he had recently received a letter from his father predicting that he would be “a disgrace1 to yourself and all your family”. Despite all this，his adventures on this ship would lead to one of the most important scientific discoveries of all time. 类文赏读　话题导入 The young man in question，Charles Darwin，was a geologist2 and naturalist，fascinated by rocks，plants and animals. He left England on the ship，the Beagle，in 1831. The journey gave him the chance to study various living things in their natural environments. After Darwin had spent some time in South America，his room on the ship was crowded with samples3 of the plants and animals he had collected. As he studied these，he asked himself the question: how did different species come to exist? At that time，people believed that all species had appeared on Earth at the same time，and had not changed since. But Darwin began to think differently. He noticed that some species of animals were very similar to each other. Maybe animals evolved4 as they adapted to their changing environments? It was just an idea，but enough to inspire Darwin to look for more evidence. When the Beagle reached the Galpagos Islands in 1835，Darwin saw a variety of new species，but it was the birds that interested him the most. Darwin noticed that there was a difference between the finches5 on each of the islands. It seemed their beaks had evolved according to what food was available on that particular island. Darwin suspected6 that the finches had evolved from a common ancestor，which had arrived on the islands a long time
