[开场白] - Smile and learn. 大家好，我有一个特别的任务。今天我要告诉你们如何节约用水。水是生命之源，没有水，所有的生物都会灭绝。因此，我们都应该尽最大努力节约用水，减少其消耗。 [水资源现状] - 你知道我们的星球有四分之三被水覆盖，但只有一小部分是可饮用的。仔细听，地球上97%的水是咸水，只有3%是淡水，而其中只有0.25%是可饮用的。如你所见，这是一个很小的比例。而且由于污染和人类消耗，这个比例每年还在减少。为了一个更可持续的地球，减少饮用水的消耗非常重要。 [浪费水的方式] - 但我们是如何浪费水的？我们是如何粗心地使用这个非常重要的资源？这是一些令人惊讶的事实。你知道每次我们用马桶冲厕时会浪费多少加仑的水吗？大约1.5加仑。如果你刷牙时不关水龙头，你会浪费多少水？4.5加仑。一个滴水的水龙头每天会浪费近8加仑的水。哇，这真是令人震惊。这就是我们每天不知不觉中浪费数百万加仑水的方式。 [节约用水的方法] - 但是，有一些方法和建议可以帮助我们在家节约用水，并为保护环境做出贡献。我们可以这样做：确保水龙头完全关闭，不要用马桶当垃圾桶，刷牙时关闭水龙头，只运行满负荷的洗衣机，重复使用洗菜的水来浇花，收集雨水并储存起来浇灌花园，淋浴而不是泡澡。你知道如果我们淋浴时关水，能省下多少水吗？40加仑。这些是减少水消耗并为更好的地球做出贡献的一些方法。 [号召行动] - 你想加入我们的使命，开始节约用水吗？现在地球在我们手中。你喜欢这个视频吗？点击订阅按钮，如果你想继续观看更多视频，请点击播放框。 **英文字幕：** [开场白] - Smile and learn.

Listen closely. 97% of the water on earth is salt water and 3% is fresh water. Of that, only 0.25% of fresh water is drinkable. As you can see, this is a very small percentage, besides it decreases every year owing to contamination and human consumption. For a more sustainable planet, it's important to reduce drinking water consumption. [浪费水的方式] - But how do we waste water? What ways do we use this very important resource carelessly? These are some surprising facts. Do you know how many gallons of water we waste every time we use the toilet as a bin? Around 1.5 gallons? Do you know how many gallons of water you waste if you don't shut off the faucet while brushing your teeth? 4.5 gallons. Also, a dripping tap wastes nearly 8 gallons of water a day. Wow, that's impressive. This is how we waste millions of gallons of water every day without even realizing it. [节约用水的方法] - But there are ways and recommendations to follow to save water at home and contribute with our grain of sand to helping the environment. Here's what we can do: 1. make sure water taps are completely turned off, 2. don't use the toilet as a garbage bin, 3. turn off the water tap while brushing your teeth, 4. run the washing machine only with a full load, 5. reuse the water for cleaning the vegetables to water the plants. 6.

Do you know how many gallons of water we could save if we turned off the water while having a shower? 40 gallons. Wow, these are some ways to reduce water consumption and contribute to a better planet. [号召行动] - Would you like to join our mission, start saving water? Now the planet is in our hands.
