Doing Work Written by Ned Jensen

Introduction "I have to do my work!" "Let's try to work harder!" "Work, work, work. That's all I do." Have you ever heard these sayings? They all have to do with work.
“我必须做我的工作!”“让我们努力学习吧!”“工作,工作,工作。 这就是我所做的一切。”你听过这些说法吗? 它们都与工作有关。
What Is Work? What is work? In everyday life, we use the word work in many ways. Work can be a place where people get paid to do a job. We might say that our computer doesn't work if it is broken. A painting or a song can be called a work of art. You might even work out in a gym. But in science, work has a special meaning.
什么是工作?功是什么? 在日常生活中,我们在很多方面使用work这个词。 工作可以是人们通过工作获得报酬的地方。 如果我们的电脑坏了,我们可以说它不工作了。 一幅画或一首歌都可以被称为艺术作品。 你甚至可以在健身房锻炼。 但在科学中,工作有特殊的意义。
In science, work is the act of moving something. Think about the times you move things. When you play, you might make a ball or jump rope move. When you do chores, you might move a vacuum or some dishes. When you ride a bike, you move the pedals with your feet. In each of these activities, you do work.
在科学中,功是移动某物的行为。 想想你移动东西的次数。 当你玩的时候,你可能会让一个球或跳绳移动。 当你做家务时,你可能会移动真空吸尘器或一些盘子。 当你骑自行车时,你用脚踩踏板。 在这些活动中,你都要做功。
There are lots of ways to do work. You do work when you push or pull a wagon down a street. Pushing and pulling are two ways to do work. You also do work when you lift books. Lifting is another way to do work. You even do work when you turn the pages of a book or twist a doorknob. As long as you are moving something, even if it's very easy, you are doing work.
做功有很多种方法。 当你在街上推或拉马车时,你是在工作。 推和拉是做功的两种方式。 当你举起书的时候,你也在做功。 举是做功的另一种方式。 当你翻书或拧门把手时,你甚至是在做功。 只要你在移动某样东西,即使它很简单,你就是在做功。
So, is everything you do a kind of work? No, it is not. You don't do work when you try to move a boulder because the rock doesn't move. Something must move, or else you have not done any work. You also don't do work when you think.
那么,你做的每件事都是一种工作吗? 不,不是。当你试图移动巨石时,你不做功,因为石头不动。 必须有东西移动,否则你就没有做功。 你思考的时候也不会做功。
