TED-Ed演讲:地球的年事有多大(02)

宣布工夫:2018-04-16内容泉源:VOA英语学习网

The United States of America's Declaration of Independence would be signed in the last half-inch.

美国的独立宣言签订在最初的半英寸。

Or if we compared geologic time to a woman stretching her arms to a span of six feet, the simple act of filing her nails would wipe away all of recorded human history.

假如我们将地质年月统一个密斯舒展的双臂长度——约莫6英尺的范畴作比拟,一个复杂的修缮指甲便会抹去整团体类汗青。

Finally, let's imagine the history of the Earth as your life: from the moment you're born to your first day of high school.

最初,让我们把地球汗青想象成你的终身:从你出生的时辰到你进入高中的第一天。

Your first word, first time sitting up, and first time walking would all take place while life on Earth was comprised of single-celled organisms.

你的第一句话,第一次起立,第一次行走通通发作在地球生物界是由单细胞生物组成的时分。

In fact, the first multicellular organism wouldn't evolve until you were 12 years old and starting 7th grade, right around the time your science teacher is telling the class how fossils are formed.

现实上,第一个多细胞生物直到你12岁的时分才呈现,也便是你开端7年级的时分,这恰好是你的迷信教师在讲堂上通知你化石是怎样构成的时分。

The dinosaurs don't appear until three months into 8th grade and are soon wiped out right around spring break.

恐龙是你在8年级上了三个月的时分才呈现的,但很快,在你春假的时分它又消逝了。

Three days before 9th grade begins, when you realize summer is over and you need new school supplies, Lucy, the Australopithecine, is walking around Africa.

9年级开端的三天前,当你发明炎天曾经完毕,你又需求新学惯用具的时分,北方猿人露西正在非洲漫步。

As you finish breakfast and head outside to catch your bus 44 minutes before school, the Neanderthals are going extinct throughout Europe.

当你吃完早餐出门追逐公交车、另有44分钟就要上课的时分,尼安德特人将从整个欧洲消逝。

The most recent glacial period ends as your bus drops you off 16 minutes before class.

近来的一次冰河时期完毕于你从公交车上上去,上课前的16分钟。

Columbus sets sail 50 seconds before class as you're still trying to find the right classroom.

哥伦布起航于你上课的50秒前,寻觅准确课堂的时分。

The Declaration of Independence is signed 28 seconds later as you look for an empty seat.

独立宣言签订于28秒钟后,这时你正在寻觅空座位。

And you were born 1.3 seconds before the bell rings.

然后你出生于上课铃响1.3秒之前。

So, you see, the Earth is extremely, unbelievably old compared to us humans with a fossil record hiding incredible stories to tell us about the past and possibly the future as well.

以是你看,地球跟我们人类比起来真的是极难以想象的高龄,化石记载隐蔽了太多过来的惊人故事,还能够包罗未来的。

But in the short time we've been here, we've learned so much and will surely learn more over the next decades and centuries, near moments in geological time.

但在我们存在的短工夫内,我们理解了云云之多,固然在将来的几十年到几个世纪我们肯定会理解更多,这仅相称于地质年月中的半晌。
