Life in the Year 3000
Narrator: A lot has changed over the last thousand years. We're better-dressed and better-looking. We're better-educated. We travel more widely. We're healthier and on average, we live much longer lives. Things seem to be getting better and better. So what will life be like in the year 3000
Girl: In the year 3000, we'll be wearing special clothes that can change according to our surroundings. Whether it's cold and wet or hot and dry, our clothes will change to keep us feeling comfortable.
Boy: And when we have science lessons at school, we won't need to use microscopes to see tiny things like cells. We'll just take a pill to make us small enough to visit and explore them ourselves!
Man: Our cars will be able to fly and go underwater. This will make it a lot easier to travel to another country or even another continent.
Boy: And we'll be going on holiday to other planets, too!
Girl: Yes, I'd love to spend my summer holiday relaxing on the Moon or climbing the mountains on Mars!
Woman: We'll apply special technology to our brains, and use it to translate any foreign language as we hear it. When we travel, we'll be able to understand and speak to everyone!
Old man: We'll develop medicines that can easily cure diseases like cancer and AIDS. What's more, we'll be able to live for more than 120years. That means even at the age of 50, we'll still be young!

3000年的生活
旁白:在过去的一千年里，发生了很多变化。我们穿着更好，看起来更好。我们受过更好的教育。我们旅行得更广泛。我们更健康，平均寿命更长。事情似乎变得越来越好。那么，在3000年，生活会是什么样的呢
女孩:在3000年，我们将穿着可以根据周围环境改变的特别衣服。无论天气是寒冷潮湿还是炎热干燥，我们的衣服都会改变以保持我们舒适的感觉。
男孩:当我们在学校上科学课时，我们不需要用显微镜来观察像细胞这样的微小事物。我们只需服用一粒药丸，使我们变得足够小，可以亲自探访和探索它们!
男士:我们的汽车将能够飞行和下水。这将使去另一个国家甚至另一个大陆旅行变得更加容易。
男孩:我们也会去其他星球度假!
女孩:是的，我很想在我的暑假里在月球上放松或者在火星上爬山!
女士:我们将把特殊技术应用到我们的大脑中，用它来翻译我们听到的任何外语。当我们旅行时，我们将能够理解并与每个人交谈!
老人:我们将研制出能够轻易治愈癌症、艾滋病等疾病的药物，更重要的是，我们将能够活120年以上，这意味着即使到了50岁，我们依然年轻!
