The third step above is primarily for presentations. When you have to give an explanation, you might not have time to prepare for it. If someone asks you a question, you can't tell them that you will need two hours to prepare before answering. 

第三步主要是做演示。当你不得不解释的时候，你可能没有时间准备，如果有人问你问题，你不可能告诉他们你需要两个小时来准备回答。

However, if it is work related, you have the ability to anticipate questions ahead of time. Think of your area of expertise and list many questions you have heard from co-workers or friends. If you speak in your own language, you know exactly how to say it without preparing for it. But in English, you don't know where to begin. List all your answers out and learn how to say it in English. If you do this, then anytime you get asked a question about your area, you can quickly respond. Here is an example with more tips. 

然而，如果它是与工作相关的，你就有能力提前预见问题。考虑一下你的专业领域，列出你从同事或朋友那里听到的众多问题，如果你用你自己的母语说话，你也能在没有准备的情况下说出来，但在英语中，你不知道从哪里开始。列出你所有的答案，并学习如何用英语表达，如果你这样做，当你被问到关于你的领域的问题时，你可以迅速做出回应。
这里有一个有更多技巧的例子。

"Can you explain the process of selling a house and the cost associated with it?" 

你能说一下买房子的过程和与之相关的成本吗?

"You can either sell the house by yourself or get an agent. Since most of the people use an agent, I will explain that. The first thing you need to do is find a sellers agent. The agent will list your house on the market. After the house is on the market, people who are looking to buy a house will find a buyers agent. The buyers agent looks through the list of houses for sale posted by the sellers agent. The buyers agent shows your house to potential buyers. When someone makes an offer, the buyers agent will let the sellers agent know about the price that the buyer has offered. After everyone agrees, the house is sold. The price associated with selling a house is based on commission. The sellers agent will get an average of 2.5 percent of the selling price and the buyers agent will get 2.5 percent as well. If the price of the house was $300,000, then each agent will get $7500, costing you a total of $15,000." 

你可以自己卖掉房子，也可以找个经纪人，既然大多数人都使用代理，我就解释一下。你要做的第一件事就是找一个卖房经纪人，卖房经纪人会在市场上列出你的房子。房子上市后，想买房子的人会找到买房经纪人，买房经纪人查看卖房经纪人所发的待售房屋清单，买房经纪人就向潜在买家展示你的房子。当有人提出报价时，买房经纪人会让卖房经纪人知道买方提供的价格，大家都同意后，房子就被卖掉了，与出售房屋有关的价格是以佣金为基础的。卖房经纪人将得到平均销售价格的2.5%，买房经纪人也将得到2.5%。如果房子的价格是30万美元，那么每个经纪人会得到7500美元，你总共要花1.5万美元。

You're first reaction might be, 'when am I ever going to be able to say all this at one time?' But it is much easier than you think. I'll explain further. 

你的第一反应可能是，“我什么时候才能把这些都说出来?”但这比你想象的要容易得多，我将进一步解释。

We have someone asking about selling a house or something. We have to explain the process. Even if you don't know the process of selling a house in America, you can use the same guideline for your area of expertise. If you can say each sentence individually, then you can say all of them put together. 

当有当有人询问关于卖房子或者其他什么的时候，我们必须解释这个过程，即使你不知道在美国出售房子的程序，你也可以用同样的方法来指导你的专业领域。如果你能单独说出每句话，那么你就可以把所有的句子放在一起说。

I start by saying there are a couple of ways to sell a house. 

我首先要说的是，出售房子有很多方法。

Then the example says you will explain the more common process. 

然后这个例子说明你将解释更常见的过程。

From here, it is basically listing steps. 

从这里开始，基本上列出了步骤。

1."The first thing you need to do is find a sellers agent." 1、

你需要做的第一件事就是找一个卖房经纪人。

2."The agent will list your house on the market." 

2、经纪人会在市场上列出你的房子。

3."After the house is on the market, people who are looking to buy a house will find a buyers agent." 

3、房子上市后，想买房子的人会找到买房经纪人。

4."The buyers agent looks through the list of houses for sale posted by the sellers agent." 

4、买房经纪人负责查看卖房经纪人发布的待售房屋清单。

5."The buyers agent shows your house to potential buyers." 

5、买房经纪人向潜在买家展示你的房子。

6."When someone makes an offer, the buyers agent will let the sellers agent know about the price that the buyer has offered." 

6、当有人提出报价时，买房经纪人会让卖方经纪人知道买方提供的价格。
”

7."After everyone agrees, the house is sold." 

7 、大家都同意后，房子就被卖掉了。

8."The price associated with selling a house is based on commission." 

8、出售房子的价格是基于佣金的。

9."The sellers agent will get an average of 2.5 percent of the selling price and the buyers agent will get 2.5 percent as well."

9、卖房经纪人将得到平均销售价格的2.5%，买房经纪人也将得到2.5%。

10."If the price of the house was $300,000, then each agent will get $7500, costing you a total of $15,000." 

10、如果房子的价格是30万美元，那么每个经纪人都会得到7500美元，你总共要花1.5万美元。

This list seems pretty simple now. Each sentence is relatively short. There is no difference between the long paragraph and the listed out items. Both contain the same words. All I did was put them together. 

这个列表现在看起来很简单，每个句子都比较短，长段和列出的项目没有区别，两者都包含相同的单词，我所做的只是把它们放在一起。

Finally, if you feel that you cannot create these sentences even in a list form, use an example that you are familiar with. I'm sure you will have an easy time creating a list if the topic is in your area of expertise. 

最后，如果您觉得不能在列表表单中创建这些句子，请使用您熟悉的示例。我相信，如果这个话题是你的专业领域，你会很容易创建出一个列表。
