解析

【分析】
这是一道词汇运用题,需结合短文语境、句子成分及语法规则(如名词单复数、动词时态、主谓一致等),从方框所给单词中选择并变形,完成短文。解题步骤:1. 通读全文,把握短文大意;2. 分析每个空格的句子结构,确定所需词性;3. 结合语境判断单词的正确形式(如名词单复数、动词的第三人称单数等);4. 代入单词检查语句是否通顺合理。
【解析】
1. 空1:空格前为fact,结合语境指“事实文件”,方框中file为可数名词,此处泛指这类文件,用复数形式files;
2. 空2:the only后需接名词,方框中planet意为“行星”,符合“地球是人类唯一可居住的行星”的语境,填planet;
3. 空3:空格前forests是复数主语,需填谓语动词,方框中cover意为“覆盖”,一般现在时,主语复数用原形,填cover;
4. 空4:hot后需接名词,方框中area意为“地区”,此处指不同的地区,用复数形式areas,填areas;
5. 空5:10,000后需接可数名词复数,方框中metre意为“米”,复数为metres,填metres;
6. 空6:that引导定语从句,先行词planet是单数,谓语动词需用第三人称单数,方框中support意为“支持”,变三单为supports,填supports;
7. 空7:want to后接动词原形,方框中explore意为“探索”,填explore;
8. 空8:a后需接名词,方框中system意为“系统”,in a system符合语境,填system。
【答案】
1. files 2. planet 3. cover 4. areas 5. metres 6. supports 7. explore 8. system
