解析:
【分析】
这是一篇关于南极洲的短文语法填空题,解题时首先通读全文把握文章大意,再分两类情况逐个分析空格:有提示词的空格优先考虑词性转换、非谓语动词、时态/语态变形等考点;无提示词的空格结合语境和固定搭配,判断需要填写的介词、连词、冠词等虚词,结合上下文逻辑逐一推导答案即可。
【解析】
1. 第一空:空格后是名词part,需要用形容词修饰,south对应的形容词southern意为“南部的”,和前面的the most构成最高级结构,表示“最南端的”,符合语境。
2. 第二空:此处是固定短语be covered with,意为“被……覆盖”,是固定搭配,因此填介词with。
3. 第三空:此处用不定式作目的状语,表达“来自世界各地的科学家前来研究冰层,目的是更多了解地球的历史”,因此填to learn。
4. 第四空:根据前文“南极洲大部分时候天气晴好、完全无风”,可知强风只在部分区域出现,也就是大部分区域强风是不常见的,给usual加否定前缀un变为unusual,意为“不常见的”,符合语境。
5. 第五空:此处是固定句型It is + 形容词 + to do sth.,表示“做某事是……的”,修饰事物“了解南极洲并不潮湿这件事”,用形容词interesting,意为“有趣的”。
6. 第六空:本句为否定句,要表达“几乎没有雪或者雨”,否定句中并列两个并列成分需要用or连接,因此填or。
7. 第七空:此处是固定搭配thousands of,意为“数千的、成千上万的”,用来描述结冰的海域绵延数千公里,因此填thousands。
8. 第八空:前面有be动词is,结合语境“地球正在变暖”,是现在进行时,结构为be+现在分词,因此get变为getting。
9. 第九空:when引导的时间状语从句遵循“主将从现”规则,主句是一般将来时,从句用一般现在时,主语that是第三人称单数,因此谓语动词happen变为happens。
10. 第十空:earth(地球)是世界上独一无二的事物,前面必须加定冠词the,构成固定搭配protect the earth,意为“保护地球”。
【答案】
1. southern 2. with 3. to learn 4. unusual 5. interesting
6. or 7. thousands 8. getting 9. happens 10. the
