6.Exploration of the PolesThe North Pole and South Pole are at the top and bottom of the Earth,(25)(al)thoughyou won't find an actual pole to mark the place.The poles are the northernmost and southernmost points on the planet.The poles are the most unfriendly environments on Earth.
In the early 1900s,explorers competed to become the first (26)to reach ( reach ) the South Pole.From 1901to 1904,British naval officer Robert Scott made the first attempt.Scott got (27)farther/further ( far ) south than anyone had been before,but he failed to reach the pole.
In 1909,Ernest Shackleton of Britain led an expedition across Antarctica on sleds pulled by dogs.They were only about 100miles (about 160kilometers) from the South Pole (28)when a shortage of food forced them to turn back.
Scott finally reached the South Pole in January 1912.But (29)disappointed ( disappoint ) Scott found that Roald Amundsen had beaten him by one month.Amundsen's expedition arrived at the pole in December 1911.Amundsen was (30)an experienced Arctic explorer,and he had made careful preparations.Scott and his companions died of injury,cold,and hunger on their return from the pole.
In 1914,Shackleton (31)planned ( plan ) another expedition to the South Pole.But his ship was crushed by ice,and he had to cross 800miles (1,300kilometers) of freezing sea in a tiny boat to survive.Shackleton then returned to save his strandedmen.It was one of the greatest rescue feats in history.
In 1929,Arctic explorer Richard Byrd became the first person who flew over the South Pole.Byrd later pioneered the idea of(32)setting ( set )up permanent stations for scientific research in Antarctica.A station called the Amundsen-Scott Base has stood at the South Pole since 1977.
分析 本文是说明文,主要介绍了最神秘的地球两极--北极和南极的相关信息,它们是人类无法征服的禁区,它们独特的魅力吸引着人类探索的脚步.本文介绍了不同的探险家的科学探险的经过以及不同的遭遇.
解答 25.(al) though 本句中"你找不到一个实际的点来标出他们的位置"和"北极和南极在地球的最顶端和最低端"的前后两句存在着转折关系,故答案为(al) though.
26.to reach 当名词被序数词修饰时后面多用不定式作定语,本句中the first后面实际上省略了men,故答案为to reach.
27.farther/further 由后面的than可知,这是一个含有比较级的句子,所以所填的词应该是far的比较级;故答案为farther/further.
28.when 本句表示在他们距离南极还只有100英里的时候,由于缺乏食物而不得不被迫返回的情况,所以用when来引导一个时间状语从句;故答案为when.
29.disappointed but表示转折,后面的句子表明在他之前一个月,Roald Amundsen已经到达南极,所以Scott应该是感到失望的;故答案为disappointed.
30.an 本句是对Amundsen的介绍,说明他是一个有经验的北极探险家.故答案为an.
31.planned 本句缺少谓语动词,根据前面的时间状语In 1914可知应该使用一般过去时;故答案为planned.
32.setting 介词后面需要使用动词的ing形式来充当定语,故答案为setting.
点评 对于语法填空题要认真分析原文,搞清楚上下文之间的逻辑关系,理顺对话者的核心话题,进而根据语法结构、上下文关系推断出答案.
