(scary) than before. Suddenly, right on our screens, the trench appeared. It went on for as 6. (far) as the eye could “see”. It felt like we were in 7. (quiet) and the most interesting place on earth. We saw some of 8. (strange) deep-sea fish in the world, and they looked very real! The 3-D effects were very realistic, and it was as if we were really there!
We all thought the virtual tour was 9. (exciting) part of the whole term. We learned a lot, and our teacher said it was 10. (good) virtual trip our school had ever organized.

【分析】
这道题主要考查形容词的比较级、最高级用法，解题思路如下：
1. 先通读整篇短文，理解全文讲述的是作者和同学参加马里亚纳海沟虚拟之旅的经历，整体语境涉及不同事物的程度对比。
2. 逐个分析每个空格的提示词和句中的限定标志：
看到句中出现ever、明确的范围限定（比如in the ocean, of the whole term, our school had ever done这类表述），要优先考虑用形容词最高级，注意多音节形容词最高级要加most，最高级前通常要加定冠词the。
看到句中出现than，或者表述“逐渐变得更……”的递进含义，要使用形容词比较级。
遇到as...as的同级比较结构，中间要使用形容词/副词的原级。
3. 结合上述规则逐一匹配每个空格的正确形式，最后通读检查逻辑是否通顺。
【解析】
1. 空后有范围限定we had ever had（我们曾经经历过的所有事情中），unforgettable是多音节形容词，最高级形式为the most unforgettable，意为“最难忘的”。
2. 句意为“海洋最深的部分”，of the ocean给出明确范围，deep的最高级为the deepest。
3. 句意为“当我们一点点离海沟越来越近的时候”，是和之前的距离作对比，close的比较级为closer。
4. 空后有than提示用比较级，loud的比较级为louder。
5. 空后有than提示用比较级，scary的比较级为scarier。
6. 固定结构as + 形容词原级 + as，表示“和……一样远”，因此填far。
7. 空后有并列的最高级结构the most interesting，前后形式要保持一致，quiet的最高级为the quietest。
8. 固定结构some of + the + 形容词最高级 + 名词复数，表示“最……的……之一”，strange的最高级为the strangest。
9. 限定范围是整个学期的所有活动，exciting是多音节形容词，最高级为the most exciting。
10. 限定范围是学校曾经组织过的所有旅行，good的不规则最高级是best，前面加定冠词the，即the best。
【答案】
1. the most unforgettable 2. the deepest 3. closer 4. louder 5. scarier 6. far 7. the quietest 8. the strangest 9. the most exciting 10. the best
【知识点】
形容词比较级，形容词最高级，同级比较as...as结构
【点评】
本题结合生活化的短文语境，综合考察形容词等级变化的核心知识点，需要学生准确识别比较级、最高级的各类提示标志，同时掌握多音节形容词的最高级变化规则、good的不规则最高级变化，整体考点基础，只要熟练掌握形容词等级的使用规则就可以顺利得分。
