Module 6 Unexplained Mysteries of the Natural World

4. 解析：选D。推理判断题。此句表面意义是：我来时是无神论，离开时却是一个虔诚的信徒。用此句来表达科罗拉多大峡谷是一个神奇的地方，只有上帝才能创造出如此神秘壮丽的景色。

3. 解析：选A。细节理解题。由第四段可知：by mule train(骑骡子)，walk和by car，只是没有提到train(火车)。

2. 解析：选C。推理判断题。由前面的the great(伟人，大人物)联想猜测可知，the simple是“普通老百姓”。

10. 解析：选C。考查独立结构。根据句子结构可知，his voice ...joy应为句子的状语部分, 可排除A、B两项；his voice heavy with joy为“n.+ adj.”构成的独立结构，作状语，表示伴随情况，故选C项。

9. 解析：选B。考查情态动词can和might的用法。can表示潜在的可能性，用于否定和疑问句中表示猜测；might表示客观的可能性，常用于肯定句和否定句中表示猜测。

8. 解析：选A。考查虚拟语气。require后的从句应用虚拟语气，即should+动词原形，其中should可省略。根据句意可知，resources与exploit之间为被动关系，故选A。句意为：资源开发与保护当地的环境应同步进行。
