解析

【分析】
这是一道结合文本细节提取和课外常识拓展的英语阅读问答题,解题时可以按问题属性分步思考:1. 针对第一题询问地球一小时的定义,先定位课文中描述该活动核心属性的内容,依次提取活动的性质、固定举办时间、核心活动行为三个关键要素,再将要素整合为通顺的完整表述即可。2. 第二题询问起源的时间地点,直接定位原文中关于该活动发起主体、发起年份、发起城市的细节信息,按逻辑组织语言输出。3. 第三题询问活动可能带来的问题,定位原文中描述关灯后替代照明方式的相关内容,梳理出对应的安全隐患点即可作答。4. 第四题属于开放拓展题,结合日常积累的环保、节能相关的公益活动常识,列举符合要求的知名活动即可。
