荡秋千的英文

题目：荡秋千的英文

解：

Sit on a swing,let someone push you,and away you go.

But what happens if the person who pushed you walks away,and you want to swing faster and higher.If you’ve ever been in the second grade,you know the solution to that.Just start pumping your legs–stretching them forward then drawing them up underneath you–and you can make yourself swing higher.Have you ever wondered why this is?

Potential Into Kinetic

Swings work by converting potential energy into kinetic energy,then kinetic energy back into potential energy,over and over again.

The kinetic energy is the fast part of swinging; it’s the speed you have as you rush back and forth.

Potential energy is the high part of swinging.

The higher you go on the swing,the more potential energy you have.

Speed and Swing

Even though you’re not moving at the very top of each swing,you can think of your height as your potential for speed.A physicist would say that your kinetic energy–that is,your speed–is “stored” as potential energy at the top of each swing.

More height is more speed,just waiting to happen.

How Do You Increase The Energy?

You can increase the energy of your swing in two separate ways.

If someone pushes you,that increases your kinetic energy.

By pumping your legs,you can increase your potential energy.By raising your legs at the top of each swing,you can raise the overall center of mass of your body,effectively raising the height of your swing.

Pump after pump,the energy you burn in your legs increases your swing’s potential energy.That extra height will add up,giving you a wilder swing ride.

译文：

坐上秋千,身后一人使劲一推,你便飞了出去,翱翔半空.

但要是再身后推你的人走开了,而你仍想秋千荡得更高更快,那该如何?这个问题,只要你上了二年级,就知道该怎么做.首先用以摇晃双腿,再向前伸来,最后将腿滑向身体之下,秋千就能荡得更高.但你是否想过这是什么原理?

势能转化为动能

秋千的工作原理是将势能转化为动能,然后又将动能再转化为势能,一遍遍的重复这个过程.

动能是秋千快的一部分能量,表现为来回运动时的速度.

势能存在于秋千荡的的高度之中.

秋千荡得越高,所获得的势能也就越大.

速度与秋千

即使在秋千的顶点你并没有运动,但你仍然可以将你的高度认为是潜在的速度.物理学家会告诉你,动能,也就是速度,储存在每次摆动顶端的势能里.

这就意味着,荡得越高,速度也就越快.

如何增加能量?

以下两种方式都可以增加摇摆的能量.

要是有人在身后推你,那将增加动能.

摇晃双腿的方式,增加的是势能.当双腿达到每次摇摆的顶部,身体重心也提高,这就有效的提升了秋千高度.

不断的摇晃,双腿产生的能量将增加势能.由此,秋千会荡得更高,更精彩.

Swinging is an old Chinese game.Many ethnic groups play it and it is most popular in northeast China as a game for Korean women.

　　There are many forms of swinging completions:singles,doubles and team events for eight players.The Koreans play it like this:a bell is hung from the top of a pole set in front of the swing.The swingers try to touch the bell,swinging up to reach it,within the set time limit.The winner is the one who makes the most touches.

　　Ethnic Koreas in China live around the Yalu River and the Tumen River.There,at festival time and on holidays,swings are set up on threshing floors or under tall threes.The ringing bell,the singing and laughing can be heard in every community and the Korean Skirt Dance can be seen everywhere.

很多人此生只有很少朋友.看起来有的人更少.是好是坏都没人可倾诉.没人在身边给他们出主意,也没人和他们谈心.他们身处困难却无人可援,注定是悲惨的生活,孤独一生.

友谊是种福气,朋友多了路好走即使你物质精神都富有.朋友可以让你在悲伤时振作,可以让你在相互挑战中找到自我,可以让你在屈服时或得重生,他们一直会在身边即使生活都离你而去.他们就是那个我们想与之分享生命/生活中快乐的以及可被纪念的时刻的人.我们经常只想着在一起快乐在一起笑在一起傻去享受互助的乐趣.朋友到底给我们了多少财富以及让我们感觉被爱、被接受、被尊敬被关心?也许,无法统计,而且还在每天增长.
