本题考查选词填空，需结合语境、固定搭配和词形变化完成作答：
1. 空处和peaceful并列，用来描述青海湖的氛围，quiet意为“安静的”，符合语境，直接使用原级即可。
2. 空处修饰指事物的名词adventure，需要用-ing结尾的形容词exciting，表示“令人兴奋的”，符合全家游览石林的体验感受。
3. 固定搭配couldn't stop doing sth. 意为“忍不住做某事”，结合语境“探索泰山的美景”，需要把动词explore变为动名词形式exploring。
4. 空处位于定冠词the和介词of之间，需要填入名词，magic作名词意为“魔力”，the magic of nature即“大自然的魔力”，符合语境。
5. 固定结构one of + 形容词最高级 + 可数名词复数，表示“最……的……之一”，此处experience意为“经历”，是可数名词，需要变为复数形式experiences。

Wonders of the World
When talking about natural wonders, certain places truly stand out. Let's take a close look at the three beautiful natural places.
Mount Qomolangma lies between China and Nepal. It is 1. mountain in the world, standing at 8,848.86 metres. Climbers from all over the world try to reach its top each year.
The Sahara Desert is 2. desert of its kind in the world—almost as big as the USA. It's dry and hot during the day, but the nights in the Sahara Desert are 3. than you might expect.
The Nile River is 4. than any other river on the earth. It's about 6,671 kilometres long. It provides water for farming, so people think it is 5. river in Egypt.

1. the highest
2. the largest/the biggest
3. cooler/colder
4. longer
5. the most important/the greatest

本题主要考查形容词比较级、最高级的用法，结合基础地理常识解题：
1. 限定范围为"in the world（全世界）"，珠穆朗玛峰是世界最高的山峰，形容词最高级前需要加定冠词the，因此填the highest。
2. 限定范围为"in the world（全世界）"，撒哈拉沙漠是世界上面积最大的沙漠，形容词最高级前需要加定冠词the，因此填the largest/the biggest。
3. 空后出现比较级标志词than，前文提到沙漠白天炎热，转折逻辑说明夜晚比人们预想的更凉爽/更寒冷，使用形容词比较级，因此填cooler/colder。
4. 空后出现比较级标志词than，此处为"比较级+than any other+名词"的固定结构，表达最高级含义，尼罗河是世界最长的河流，因此它比地球上其他任何河流都更长，填longer。
5. 限定范围为"in Egypt（在埃及）"，尼罗河为当地农业提供水源，对埃及意义重大，是埃及最重要/最伟大的河流，形容词最高级前加the，因此填the most important/the greatest。
