Questions 47-50. Listen to the beginning of a lecture given by a history professor.
Good morning, class. Before we begin today, I would like to address an issue that one of you reminded me of after the last lecture. As you may recall, last time I mentioned that Robert E. Pierre was the first person to reach the North Pole. What I neglected to mention was the controversy around Pierre’s pioneering accomplishment. In 1910, a committee of the national geographical society examined Comeydore Pierre’s claim to have reached the North Pole on April 6th 1909 and found no reason to doubt him. This judgment was actually confirmed by a committee of the US congress in 1911. Nevertheless, Pierre’s claim was surrounded by controversy. This was largely due to the competing claim of Doctor Frederic Cook who told the world he had reached the Pole a four-year earlier. Over the decades Pierre was given the benefit of the doubt, but critics persisted in raising questions about his navigation and the distances he claimed to have covered. So the Navigation Foundation spent an additional 12 months of exhaustive examination of documents relating to Pierre’s polar expedition. The documents supported Pierre’s claims about the distances he covered. After also conducting an extensive computer analysis of photos taken by Pierre at the pole, they concluded that Pierre and his companions did in fact reach the near vicinity of the North Pole on April 6th, 1909. OK, today we’re going to talk about exploration of the opposite end of the world. I assume you all read chapter 3 in our text and are now familiar with the names: Emerson and Scott.
OK，下面我把考点用粗体阴影标出。看看你划得对吗？
