I often walk to school. I turn off the tap when I'm brushing my teeth. We all live on the earth. Language points 在环保话题中，我们通常用一般现在时来描述经常发生的动作、个人的生活习惯或客观真理。因为主语是“I”或“We”，所以动词要用原形。当主语是第三人称单数（he/she/it）时，动词要加-s或-es。 句型结构： 肯定句： 主语 + 动词原形 + 其他. (I/We/You/They) 肯定句： 主语 + 动词第三人称单数 + 其他. (He/She/It) 否定句： 主语 + don't/doesn't + 动词原形 + 其他. Language points 祈使句——发出建议与指令 Ride a bike, take a bus or walk to school. Use both sides of the paper. Turn off the tap when you're brushing your teeth. Buy only the things you really need. Language points 在给出环保建议、规则或指令时，英语常使用祈使句。祈使句的特点是省略主语（You），直接以动词原形开头。在环保倡议中，祈使句显得直接、有力。 句型结构: 肯定祈使句： 动词原形 + 其他. (e.g. Turn off the lights.) 否定祈使句： Don't + 动词原形 + 其他. (e.g. Don't waste water.) 强调/礼貌祈使句： Please + 动词原形 + 其他. (e.g. Please plant more trees.) Language points 时间状语从句——when引导的动作同时发生 I turn off the tap when I'm brushing my teeth. Turn off the lights when you're not using them. Language points “when”在这里表示“当……的时候”。它引导一个从句，表示主句动作发生的时间背景。在表达环保习惯时，常用来描述“在某个特定动作进行时，我们要做另一件事”。 句型结构： 主句 (一般现在时) + when + 从句 (现在进行时/一般现在时). e.g. We should save water when we are washing hands.
