时间已是2264年4月4日。这一天我刚满6岁,我的亲人、朋友都送给我许多礼物:纯净的氧气、纯净的水,无污染的食物……这些东西对我来说都很陌生。爷爷告诉我这些东西是从他父亲居住过的地球上运来的,在这里乃至整个银河系都算是稀有物品。我问爷爷地球是什么地方,比这里好吗?是不是也像我们一样每天呼吸科学家研制的合成气体,出门坐飞船?而爷爷的回答却是:明天我带你到地球上“参观”一回,你就会知道的。 The time is April 4, 2264. On this day I was just 6 years old. My relatives and friends gave me many gifts: pure oxygen, pure water, and unpolluted food... These things are unfamiliar to me. Grandpa told me that these things came from the earth where his father lived, and here even the entire galaxy is considered a rare item. I asked my grandfather what the earth is, is it better than this? Is it also like we breathe synthetic gas developed by scientists every day and go out to sit on a spaceship? Grandpa’s answer is: tomorrow I will take you to the earth and “visit” it once. You will know.
