【分析】
首先通读对话,明确对话围绕“周末计划去历史博物馆,讨论文物回归的相关话题”展开。解题时需结合每个空的前后句语境,分析句子间的逻辑关系(如问答对应、话题衔接等),逐一匹配选项:
1. 空前B表示无计划,空后A提出活动建议,故1空需填询问对方想法的句子;
2. 空前A介绍博物馆有珍贵文物,空后提及文物归还的好消息,故2空需填引出好消息的句子;
3. 空后A以“Because...”回答原因,故3空需填询问原因的句子;
4. 空前B表达对文物回归的认同,空后A补充说明现状,故4空需填表示赞同的句子;
5. 空后A说“See you then!”,故5空需填回应再见的句子。
【解析】
1. 选B:B选项“Do you have any ideas?”(你有什么想法吗?)承接上文B“Not really.(没什么计划)”,引出A的活动建议,符合语境;
2. 选F:F选项“And there's been good news recently.(最近有个好消息)”承接上文A对博物馆的介绍,引出下文“很多国家归还文物”的内容,符合逻辑;
3. 选D:D选项“Why are they doing that?(他们为什么这么做?)”对应下文A的“Because China is becoming stronger.”,是对原因的提问,符合问答逻辑;
4. 选C:C选项“I totally agree with you.(我完全同意你)”承接上文B“These cultural relics are part of our history and should come back home.”,表达赞同,符合语境;

【分析】
这是一篇科技类语法填空题,需结合语境、语法规则逐一分析每个空:1. 考查被动语态,主语指代SPA盆地,与call是被动关系,用一般现在时;2. 考查名词复数,宇航员是可数名词,此处指多名宇航员;3. 考查形容词最高级,前面有定冠词the,表范围(月球上),用最高级;4. 考查定冠词,月球是独一无二的天体,前加the;5. 考查连词,此处表时间,当撞击时,用when;6. 考查介词,固定搭配lead by;7. 考查动词时态,主语是this,第三人称单数,一般现在时;8. 考查副词,修饰动词stayed;9. 考查将来时的被动语态,动作发生在将来且是被动;10. 考查物主代词,修饰名词side。
【解析】
1. 主语it指代SPA盆地,与动词call构成被动关系,描述客观事实,用一般现在时的被动语态,故填is called;
2. astronaut是可数名词,此处指多名宇航员,应用复数形式,故填astronauts;
3. 由空前的the及范围on the Moon可知,此处应用形容词最高级,big的最高级是biggest,故填biggest;
4. 表示独一无二的事物(月球)前需加定冠词the,故填the;
5. 此处引导时间状语从句,意为“当……时”,应用连词when,故填when;
6. 固定搭配lead by表示“由……领导”,故填by;
7. 主语this是第三人称单数,描述客观事实,用一般现在时,动词用三单形式,故填shows;
8. 此处修饰动词stayed,应用副词,quiet的副词是quietly,故填quietly;
9. 主语chemicals与collect构成被动关系,动作发生在将来(2027年),应用一般将来时的被动语态,结构为will be+过去分词,故填will be collected;
10. 此处修饰名词side,应用形容词性物主代词,it的形容词性物主代词是its,故填its。
【答案】
1. is called 2. astronauts 3. biggest 4. the 5. when 6. by 7. shows 8. quietly 9. will be collected 10. its
【知识点】
