【分析】
首先通读整篇短文，明确本文主题是介绍地球上的各类自然奇观，再结合给出的备选词汇，逐个空结合上下文语义、语法规则、固定搭配来筛选匹配，同时注意部分词汇需要根据词性要求做变形：比如形容词变名词、动词变过去式、形容词变否定派生词等，最后再通读完整填好的短文，验证逻辑和语法是否通顺，确保没有错漏。
【解析】
1. 第一空：句意为世界最高峰珠穆朗玛峰高8848.86米，描述事物高度的常用结构为“基数词+长度单位+high”，因此填high。
2. 第二空：句意为死海拥有地球上海拔最低的陆地表面，surface表示“表面”，完全符合语境语义，因此填surface。
3. 第三空：句意为死海的位置在海平面以下约416米，below sea level是固定常用搭配，意为“在海平面以下”，因此填below。
4. 第四空：句意为科学家关于海洋的研究展现了更多惊喜，空格前是名词所有格Scientists'，后面需要接名词，research表示“研究”，符合语义，因此填research。
5. 第五空：句意为马里亚纳海沟最深点的深度约为11000米，空前有不定冠词a，需要把给出的形容词deep变形为名词depth，构成固定结构a depth of...表示“……的深度”，因此填depth。
6. 第六空：句意为2020年中国深海探测器奋斗者号成功下潜来研究这片特殊区域，时间状语In 2020是一般过去时的标志，动词dive要变为过去式dived，因此填dived。
7. 第七空：句意为科学家在海沟中发现了很多不寻常的生物，结合深海的特殊环境，要把给出的usual变为否定派生词unusual，修饰名词creatures，因此填unusual。
8. 第八空：句意为这些生物生活在海沟的底部，at the bottom是固定搭配，意为“在底部”，符合海沟的场景描述，因此填bottom。

【分析】
解题时首先通读完整对话和所有备选选项，理清对话的核心话题是两人围绕中国的特色地理景点展开交流，整体按照“介绍东北平原→询问其他特色地点→介绍吐鲁番盆地的海拔特点→介绍当地气候的影响”的逻辑推进。接下来逐空匹配上下文线索：1. 第9空前文刚点明最大平原是东北平原，后文李明说想了解更多相关信息，空格内容必然承接东北平原的相关属性；2. 第10空后文王林用Yes作答，还引出了吐鲁番盆地这个新地点，说明空格是提出询问其他地点的一般疑问句；3. 第11空后文李明的提问明确提到了“低海拔”，说明空格内容必须提前铺垫吐鲁番海拔低的特点；4. 第12空前文刚提到吐鲁番夏季炎热干燥，空格需要承接这种气候的相关结果，逐一匹配选项就能得到正确答案。
【解析】
9. 前文对话刚确认中国最大平原是东北平原，后文李明表示想要了解更多关于它的信息，B选项“它被称为中国的‘粮仓’，生产大量小麦和玉米”是对东北平原特点的补充介绍，衔接上下文逻辑通顺，故选B。
10. 后文王林用Yes作答，同时引出吐鲁番盆地这个其他的特色地点，D选项“中国还有其他特别的地方吗”是符合语境的一般疑问句，和答句完全呼应，故选D。
11. 后文李明紧接着提问“低海拔会影响那里的天气吗”，A选项“它是中国地势最低的地方，部分区域低于海平面”正好点明了吐鲁番海拔低的属性，为后文的提问做铺垫，故选A。
12. 前文王林提到吐鲁番夏季炎热干燥，C选项“这种天气非常适合种植葡萄这类甜的水果”承接了炎热干燥的气候特点，说明该气候的优势，逻辑连贯，故选C。
【答案】
9. B 10. D 11. A 12. C
【知识点】
情景交际，对话逻辑衔接
【点评】
本题结合基础地理常识考查英语对话补全能力，所有选项的线索都在上下文中有明确呼应，学生只要顺着对话的话题推进逻辑，抓住答句和问句的对应关系、后文出现的特指名词的前文铺垫线索，就可以快速选出正确答案，同时还能在做题过程中积累相关的中国地理小知识。

Ⅲ. Read and answer the questions.阅读并回答问题。
Last week, our science class had a video call with Dr Lee, a deep-sea researcher. He shared
fascinating facts about exploring the dark, cold ocean depths.
First, he introduced us an amazing deep-sea life. The Greenland Shark, one of the largest
hunters there, grows only about one centimetre per year. We also learned about the anglerfish, which uses a special light on its head to attract smaller fish in the darkness.
Next, Dr Lee explained the ocean floor's landscape. "It's not flat," he said. He showed us
maps showing huge underwater mountains longer than any on land, deep trenches that could
swallow mountains, and wide flat plains. In some places, there are even hot springs
supporting unique ecosystems.
We were curious about exploration. Dr Lee told us the "Trieste", which first
reached the deepest part of the Mariana Trench in 1960, and China's "Fendouzhe", which also
successfully explored there. These boats helped scientists study the deep.
My friend Tom asked,"Why does the deep sea matter to us?" Dr Lee explained,"It helps
control the earth's climate by moving heat around. The special animals there might also help us
make new medicines one day. " Then he said seriously,"But we must protect it. Pollution from
human activities, like plastic bags, has been found even at the deepest point. "
This talk taught me that the deep sea is a mysterious world closely linked to our own life. It
holds both wonders and warnings, reminding us of the importance of exploring and protecting our
oceans.
13. Is the ocean floor a completely flat and empty place according to the passage?

14. How does the anglerfish find its food in the dark?

15. Which vessel was the first to reach the deepest part of the Mariana Trench?

16. Why is the deep sea important to us?

17. What should we do since the pollution has reached the deep sea?

Ⅲ.13. No,it isn't./No.
14. It uses a special light on its head to attract
smaller fish./By using a special light on its
head to attract smaller fish.
15. The "Trieste".
16. Because it helps control earth's climate,and
the special animals there might help us make
new medicines.
17. We should protect the ocean and stop throwing
rubbish into the sea.(言之有理即可)
