参考答案与解析
1.B 解析:原文第一句明确指出地震的第三个影响是“change the time”。
2.B 解析:原文为“made the earth spin faster”,其中“spin”意为“旋转”。
3.A 解析:原文明确给出数字“shortening the day by 1.6 microseconds”。
4.B 解析:原文分别说明两次地震:“The 2004 Sumatra quake shortened the day by 6.8 microseconds。”
5.B 解析:原文给出了丛林大火常见的原因:“the Australian climate is generally hot and dry.”
6.C 解析:原文并列了丛林大火的三种后果,第三个是“endangered many species”。“endangered”意为“使…濒危”。
7.B 解析:原文“evolved alongside fires”意为“与火灾一同进化/演化”,这是一个关键搭配。
8.B 解析:原文明确指出是“historic and recent fires”共同塑造了澳大利亚的自然特征。
9.C 解析:原文将黑死病描述为“a pandemic”,即“大流行病”。
10. C 解析:原文“widely believed to have been the result of plague”表明普遍认为其原因是“plague”(瘟疫)。
11. C 解析:原文“was hard hit by”是一个固定搭配,意为“受到…的沉重打击”。
12. A 解析:原文给出的数字是“25 million people”。

14. B 解析:“shifted the earth’s mass”是科学描述,指改变了地球质量的分布,即移动了部分地球物质。
15. C 解析:“shortening”意为“使变短”,因此“shortening the day”就是使一天的时间变短。
16. C 解析:“common throughout”意味着在许多地方都常见,即频繁发生。
17. B 解析:“endanger”意为“使处于危险中”,对物种而言,最大的危险就是灭绝(disappearing)。
18. A 解析:“pandemic”(大流行)的定义就是疾病在全国或全球范围内广泛传播。
19. B 解析:“rough estimate”指“粗略估计”,即大概的、不精确的数字。
20. B 解析:全文以客观口吻介绍了三种灾害的科学事实(地震影响时间、丛林大火与生态、黑死病历史数据),主要目的是提供信息。
