现在，来自美国之音学习英语的单词和它们的故事。
Technology is always progressing. Today, many modern devices can be controlled by touch or voice. This has led to some traditional electronic controls – such as dials and switches – being replaced with new technologies.
技术总是在进步。 如今，许多现代设备都可以通过触摸或语音进行控制。 这导致一些传统的电子控制装置（例如刻度盘和开关）被新技术取代。
Digital displays have also become increasingly common. For example, digital number readouts have long replaced the hands on many clocks.
数字显示器也变得越来越普遍。 例如，数字读数早已取代了许多时钟上的指针。
Many other devices also now operate purely with digital tools instead of mechanical systems.
许多其他设备现在也纯粹使用数字工具而不是机械系统进行操作。
But some expressions and idioms used by English speakers still describe older technologies.
但英语使用者使用的一些表达方式和习语仍然描述较旧的技术。
First, let’s talk about dials. These controls are used for changing settings on a piece of equipment, like a radio or old television. We use the dial to tune in to a specific channel.
首先，我们来谈谈表盘。 这些控件用于更改设备（如收音机或旧电视）的设置。 我们使用旋钮调到特定频道。
That’s where the expressions dialed in and tuned in come from. If we are dialed in or tuned in to a radio or television program, we can hear it clearly. There is no noise or static.
这就是拨入和调入的表情的来源。 如果我们拨通或调到广播或电视节目，我们就可以清楚地听到。 没有噪音或静电。
The same can be said when using these terms in personal conversations. For example, if you are dialed in to a project or problem, you know exactly what needs to be done. You are thinking clearly about it and remain very focused.
在个人对话中使用这些术语时也可以这样说。 例如，如果您接到一个项目或问题的电话，您就确切地知道需要做什么。 你思考得很清楚并且保持高度专注。
And when you are tuned in, you understand clearly what is going on around you.
当您收听时，您会清楚地了解周围发生的事情。
“Don’t touch that dial” and “stay tuned” are two ways to tell someone to keep watching or listening to a program.
“不要碰那个旋钮”和“继续收听”是告诉某人继续观看或收听节目的两种方式。
Now, let’s talk about switches.
现在，我们来谈谈开关。
These are built to either be off or on. There are no in-between settings like with a dial. So, when we flip the switch, we make something happen quickly and easily. It can also mean that we suddenly change something.
这些被设计为关闭或打开。 没有像表盘那样的中间设置。 因此，当我们按下开关时，我们就能快速轻松地让事情发生。 这也可能意味着我们突然改变了一些事情。
Let’s listen to an example.
让我们听一个例子。
The restaurant’s change to all organic food happened slowly over time. It wasn’t a matter of flipping a switch.
随着时间的推移，餐厅对所有有机食品的改变是慢慢发生的。 这不是按一下开关的问题。
Now, for our last expression -- to move the needle.
现在，我们的最后一个表达是——移动指针。
Needles on measuring devices like a scale move to show a desired level has been reached. So, when something moves the needle, it causes a noticeable change in something, usually for the good.
测量设备上的指针（如秤）移动以显示已达到所需的水平。 因此，当某件事发生重大变化时，它会导致某些事情发生明显的变化，通常是好的。
And that’s all the time we have for this Words and Their Stories. Don't forget to tune in again for another story about American English expressions.
这就是我们阅读《言语及其故事》的所有时间。 不要忘记再次收听另一个有关美式英语表达的故事。
