This lesson will give some guidelines on how to explain something and how to speak during presentations. Because I cannot be specific to every topic, I'll choose general ones. You should primarily be looking at the structure and style for this Business English lesson. 

这节课将给出一些关于如何解释某事以及如何在介绍的时候说的指导原则，因为我不能具体到每个话题，我将选择一般性的话题，你应该首先看一下商务英语课的结构和风格。

It is understandable if you feel nervous or uneasy about having to explain something in English. Because English is not your first language, it is very difficult. However, in the office, you will be in many situations when you have to explain something. Here are 3 tips to make your explanation or presentation easier. 

如果你对用英语解释某事感到紧张或不安是可以理解的，因为英语不是你的母语，所以很难。然而，在办公室里，当你不得不解释一些事情的时候，你会遇到很多情况。这里有3个技巧可以让你的解释或演示更容易。

First, you should not talk fast. I work in a large company with many different people from all over the world. The hardest time I have when listening to someone is when they talk fast with a bad accent. The problem they have is that they are fluent and comfortable speaking English, but they do not realize how bad their accent is. If you speak slower, you can avoid this problem. Unless you are certain that your accent is understandable, always speak a little slower. 

首先，你不应该说得太快，我在一家大公司工作，有很多来自世界各地的人。当我听别人讲话的时候，最困难的是他们说话的时候太快而且发音不好。他们的问题是，他们说英语很流利，很舒服，但他们没有意识到他们的口音有多糟糕。如果你说得慢一点，你就可以避免这个问题，除非你确定你的口音是可以理解的，否则说话要慢一点。

Second, you should speak clearly. Say each word clearly and emphasize the important words. Even if they don't understand every word in your sentence, they will understand the whole meaning with proper emphasis. 

第二，说话要清楚。把每个单词都说清楚，并着重强调重要的单词，即使他们不理解你句子中的每一个字，他们也会正确地理解整个意思。

Third, prepare and practice ahead of time. You should record yourself and listen to the recording. You should also get an American friend to judge you. This is a lot of work you have to do in the beginning, but this is VERY important. Even though it will make your presentation or explanation clearer and better, that is not the reason I am saying you should do the recording and getting a friend to listen. The reason why this is so important is because you are laying the foundation on proper communication in regards to intonation and pronunciation. For example, if you don't do this, you might think you don't have a problem and you will continue to practice incorrectly. Soon, you will be someone who can talk fast but have terrible pronunciation. You will become the type of people I described... hard to understand. If you take the time to practice for several hours before each presentation, you will be practicing the correct way to enhance your English abilities.  

第三，提前准备和练习。你应该录下来，并听录音，你也应该找个美国朋友来评判你，一开始你必须要做很多的工作，但这是非常重要的。
即使它能让你的陈述或解释变得越来越清晰，但这并不是我说你应该做录音并让朋友听的原因。这之所以如此重要，是因为你要在语调和发音上打下良好的沟通基础。例如，如果你不这样做，你可能认为你没有问题，你将继续不正确地练习。很快，你就会成为一个说话很快但发音很糟糕的人，你将成为我描述的那种人……难以理解。如果你在每次说话前花时间练习几个小时，你就会练习正确的方法来提高你的英语能力。
