解析

【分析】
本题为语篇型语法填空,需结合语境、语法规则及词形变化确定每个空的正确形式。具体思路:1. 第1空根据“世界第三长的河流”,用形容词最高级结构;2. 第2空描述过去夏天的天气,结合后文过去式用一般过去时;3. 第3空与前文过去场景呼应,用一般过去时;4. 第4空考查there be结构的非谓语,用现在分词;5. 第5空need of后接名词,需转换词形;6. 第6空150 million后接可数名词复数;7. 第7空由than可知用形容词比较级;8. 第8空2020年是过去时间,用一般过去时;9. 第9空表示“第一部”,用序数词;10. 第10空描述过去经历,用一般过去时。
【解析】
1. 形容词最高级:“世界第三长的河流”需用long的最高级形式longest;
2. 一般过去时:描述过去夏天的天气,主语weather为单数,be动词用was;
3. 一般过去时:与前文过去动作(stood)时态一致,go的过去式为went;
4. 非谓语动词:there be sb doing sth为固定结构,表伴随状态,故用sitting;
5. 名词形式:need of后接名词,protect的名词形式为protection;
6. 名词复数:150 million后接可数名词复数,year变years;
7. 形容词比较级:由than可知用比较级,dirty的比较级为dirtier;
8. 一般过去时:2020年是过去时间状语,pass的过去式为passed;
9. 序数词:表示“第一部”,用one的序数词first;
10. 一般过去时:描述过去参加活动的经历,join的过去式为joined。
【答案】
1. longest 2. was 3. went 4. sitting 5. protection 6. years 7. dirtier 8. passed 9. first 10. joined
【知识点】
