Effective communication

有效沟通

If you heard someone shout, “Hey you!” from across the room, how would youreact?

Just these two words can carry much information.They could be interpreted as a welcoming

greeting from a close friend, especially if accompanied by a gentle smile.When spoken

by a stranger, they can function as a means of attracting your attention.Much of what

we communicate is dependent not only on the words we use, but also on how we use them.So,

let’s look a little deeper into the topic of communication.

如果你听到有人喊:“嘿，你! ，你会有什么反应? 仅仅这两个词就能传达 很多信息。这句话可以被理解为来自亲密朋友的欢迎问候，尤其是伴随着温 柔的微笑。当陌生人和你说话时，它们可以作为一种吸引你注意力的方式。我们交流的内容不仅取决于我们使用的词语，还取决于我们如何使用它们。所 以，让我们更深入地了解一下沟通这个话题。

Communication is the exchange of information between a sender and a receiver.The

sender encodes a message and sends it face to face, or through video,
