解析
【分析】本题为英语阅读判断正误题，解题思路是：先准确理解每个句子的含义，再结合日常环保常识判断句子表述是否正确，逐一完成5道小题的判断。
【解析】1. 句意“很多资源正在耗尽”，符合现实情况，故判断为正确（√）；2. 句意“快速冲澡只能节水，不能节能”，实际上快速冲澡既减少水的使用（节水），也减少加热水所需的能源消耗（节能），表述错误（×）；3. 句意“使用LED照明能节能”，LED灯能耗远低于传统灯具，确实能节能，表述正确（√）；4. 句意“不用时拔掉电脑和电视插头是节能的方法”，电器待机状态会消耗电能，拔掉插头可避免待机耗电，属于节能方法，表述正确（√）；5. 句意“小改变不能产生大影响”，生活中诸多小的环保行为（如随手关灯、节约用纸）积累起来能产生大的积极影响，表述错误（×）。
【答案】1. √ 2. × 3. √ 4. √ 5. ×
【知识点】英语阅读判断、环保常识应用
【点评】本题将英语语言理解与环保常识相结合，考查学生的阅读理解能力和常识应用能力，题目贴近生活，难度适中。
