第三句：
他们自己设计路线，自带帐篷、厨具以及其他必备的生活用品。
译文一
They design the routes on their own and bring themselves tents, kitchenware, and other necessary living supplies.
思路：本句主语为 “他们”，谓语为 “设计” 和 “带”，两个动词之间可用并列连词 and 连接。
译文二
They work out their own routes, bringing tents, cooking tools and other essential daily items.
译文三
They plan travel routes independently, equipped with tents, kitchen utensils and other basic daily supplies.
