The first way applies when you greet people in person for the first time 当你首次亲自问候人家时

To make a positive first impression when you meet new people, include the following as part of your greeting: 当遇到新人时想要留下美好的第一印象，那你的问候部分要有下面几点：

a warm smile, an introduction that includes your first and last name, a welcoming comment, direct eye contact and a firm handshake, if appropriate. 暖心的微笑，含有你姓和名的一个介绍，受人欢迎的一个评论，眼神的直接接触，如若合适一个正式的握手。

I also recommend repeating the person's name. 我还推荐重复这个人的名字。

For example, "It's very nice to meet you Bob." 例如，很高兴见到你鲍勃。

I have learned that by repeating someone's name,you are demonstrating you have interest in them. 我发现通过重复对方的名字，你可以展示你对对方感兴趣。

The second way is when you meet people who don't tell you their name-If this occurs, simply ask them for their name. 当你见到没有告诉你名字的人时--这种情况下，你可以简单的问下他们的名字。

I might say, "I didn't catch your name." 我可能会说，"我没有记住你的名字。"

After they respond, I will repeat their name as described in the previous point. 在他们回答后，我会按照前一个点上描述的那样重复他们的名字。

The third way is when someone introduces you and does not include your name 当有人介绍你却没有介绍你的名字

When you are introduced to someone and the person making the introduction doesn't include your name,  你被介绍给某人但这个介绍人在介绍你时没有介绍你的名字，

it's likely they forgot it or they don't know how to make a proper introduction. 很有可能他们忘记了或不知道怎么合适的去介绍。

In this case, offer a warm greeting as I described in the first tip and be sure to include your first and last name. 这种情况下，像我在第一条描述的那样主动给予一个热情的包含姓名的介绍。

This will prove you are paying attention and that you realize your name was omitted from the introduction. 这能证明你很在意并且你也意识到你的名字被忽略了。
