Hi, im Evelyn!你好呀,我是小田园。真的是好久不见啊哈哈,不过不论如何,在经历了期末考试和旅行之后我最终还是回来啦!!所以今天我来讲讲有关energy能量的小知识。
Did you ever think about, why do we get tired? It is an interesting question. If you want to find out the answer,we need to dig deeper, start from the ‘enery’.
So first,what is energy? Energy makes things happen--nothing in the universe would work with out energy,but you can see what it does to things around you. Because of energy, cars move and the airplanes fly, lamps give out light, drums make music and fires give off heat.
Lots of things give out energy in many different forms too. Here are some examples.
Fire is makes heat energy, playing drum makes sound energy, food is chemical energy, torch makes light energy.
Now you know what is energy, let’s get back to the question, why do we get tired? We can change this question to, Why do i run out of energy. It is because you use it! Walking running and jumping all need energy. Without it you wouldn’t be able to talk, write, read or even sleep! Energy is stored inside your body and comes from your food. That’s why you get hungry - your body is telling you to put back some of the energy you’ve used!
接下来是生词环节——
Energy能量,精力,活力。这个单词是全文的主题,绝对不能忘了哦~
Heat高温,热能。你知道三种热能的传递方式吗,它们分别是convection conduction and radiation,对流,传导,和辐射。听起来很高深,但实际上很简单,我举个例子你就懂了:炒菜的时候煤气灶台上的火让炒锅热起来,这是convection对流;你用手碰到了发热的暖宝宝,这是conduction传导,把食物放进微波炉里转一会儿再拿出来,食物变热了,这是radiation辐射。
今天的生词也不多所以添加了一些有关热传递的小知识,你记住了吗?
那么接下来是中文翻译。你有没有想过,为什么你会觉得累?这是一个十分有趣的问题,我们要从它的根源,能量讲起。
首先,什么是能量?它的用处可大了,如果没有了能量,那么宇宙中的任何东西将无法运转,是不是很无法想象?所以我们换一个角度看一看,汽车能跑,飞机能飞,台灯能亮,打鼓能响,火焰散发热,这些近在我们身边的事物都离不开能量,有了它,才能运转。
能量也有很多不同的形式,举几个例子,火是一种热能,火把是一种光能,食物是一种化学能。
在你知道什么是能量之后,让我们重新回到那个问题,你为什么会感觉累?而我们可以把它换成另一个问题,为什么你会失去能量?这是因为你正在使用它,包括此时此刻!跑步,跳跃,都需要能量。没有了它你甚至不能交,书写,阅读,连睡觉都不行!你身体里的能量来源于你吃下去的食物。这就是为什么你会觉得饿,因为你的身体在跟你说:我需要更多的能量!
better and better! and i like the music
小田园,你的英语口语是怎么练的啊
good
嗯有一个问题?微波炉热食物不是微波对食物里的水分子做功嘛
