答案
1.coldest 此处表达:地球上最寒冷的地方,结合设空前的定冠词the可知此处考查形容词的最高级。
2.the 第五大洲,序数词前应加the。
3.is covered 设空处是句子的谓语动词,要用被动语态,且surface是一个不可数名词。
4.driven 考查非谓语动词。设空处动词与其逻辑主语之间是被动关系,所以要用过去分词形式。
5.which 考查非限制性定语从句,修饰先行词penguins,定语从句中缺少主语,所以要用关系代词which。
6.trapped 此处为“with+宾语+宾补”结构,设空处动作与宾语之间是被动关系,所以要用过去分词形式。
7.that 考查强调句式,被强调部分是句子的时间状语not until 1895,所以答案为that。
8.on 考查固定搭配:set foot on踏上……;进入……。
9.to study 考查不定式作状语,表示目的。
10.peace 并列连词and连接两个名词。
