师：Class begins. Stand up. Good morning, everyone.

生：Yes.
师：This is our headmaster, Mr. James Morris. He is going to invite parents to the library for the opening. So he made an invitation. Try again, invitation.
生：Invitation.
师：Invitation, invitation. Okay, right. Think about a question. What key points or what content could be in an invitation? Think about it. We focus on the content first. For example, at the beginning of an invitation, there is "Dear Mary", "Dear James", etc. That's to whom the invitation is addressed. And at the bottom, there should be...
生：The writer.
师：The writer, whom the invitation is from. Ray, what else could be in an invitation?
生：When, where, the place of the event. People should know that.
师：Oh, where. And also when. When is the time for this event? Time and place are very important. What else?
生：Why.
师：Why, yes. The purpose for this event, right? What else?
生：What things to do.
师：Oh, what things should people do. See, seems you do know some basics about making an invitation. Is there anything missing? Don't worry. We're learning now from the headmaster's invitation. Now you can see the whole content. Shall we find the key points one by one? First question, whom is this invitation to? Together, please.
生：The parents.
师：Okay, let me underline the answer. It is to the parents. And whom is it from? Together, louder.
生：Mr. James Morris, our headmaster.
师：And then, as you can see, there are more questions. Please read this by yourself and answer those questions. If you find the answers, underline them like this. Okay, you have one and a half minutes to do it. Take out your handouts. One, two, go. And then, please work with your partners to discuss the answers. Okay, go.

师：Who wants to share your discussion? First question, why did the headmaster make the invitation?
生：I would like to invite you to the opening of our library in the school in Wuhan.
师：No, the big thing is... together.
生：The opening of our new library.
师：Right. That's very important for people to know why they are invited. And where does the school hold the main event? Just now she mentioned a little bit. Who can finish the whole sentence? You, please.
生：The school will hold it on the morning of Wednesday, November fifteenth at nine in the school hall at ISA Wuhan.
师：Right. It's necessary for people to know the time and place so that they won't be late for it. Next question, what will parents do for the new library?
生：They will bring one book as a gift for the new library.
师：Wow, to bring a book for the library. Isn't it interesting? By doing so, people will feel they are much involved in this event. Last question, and very important, when and how to reply? Can you answer me together, louder?
生：（回答相关内容）
师：Wow, see, we have found another new point, another key point, that is how and when to reply. With the replies, the school will know how many people will come so they can make good preparation for it, right? Okay, very good, everyone. We have worked out all the key points, and we know the headmaster should mention those points in the invitation. Then what sentences did he use to make parents know these key points? This time, let's focus on its language. We'll study the language of this invitation. Hmm, we are going to look for some useful sentences. First one, what sentence did the headmaster use to ask the parents to come? Who has found it? Show me your hand. You can read it for us. Use the microphone, please.
生：I would like to invite you to the opening of our library in the school hall at ISA Wuhan.
师：Wow, it's at the very beginning of this invitation, right? And you know what? I have found a useful structure to invite others. What is it? Hmm, ready, together.
生：I would like to invite you.
师：Hmm, it's very useful. And then, what sentences did the headmaster use to ask the parents to help and to reply? Please find those two sentences and show me your hands. Read them for us if you're ready.
生：I would also like to invite each parent to... and please reply in writing to this invitation by...
师：Okay, oh, wow. You have mentioned those key points and also focused on the key sentence structure, right? Yeah, from those sentences, we got another one. It is a similar one, "I would also like to..." And then, to ask others to reply, there is "please..." Read it again. Okay, yeah, it's also very helpful for us to use later. Now, class, eyes on those sentences and structures. How do they sound to you? Let's take the first sentence for example. Make it bigger. Please read it again. I have another version. Please read this. "Hi, can you come to the opening of our library at ISA Wuhan?" What's the difference between them? Hmm, I put these two together for you to compare. Number one, number two. Which one is proper to say to your close friends? Show me your fingers. One, go.
生：（多数学生选择第二个句子）
师：Yeah, and which one is proper for you to say to very important people? Hmm, which one, number one or number two? Show me your fingers. Go.
生：（多数学生选择第一个句子）
师：So we say number one is in a formal tone. What's the meaning of "formal"? I'm wearing a suit. It looks very formal. What's the meaning? Louder.
生：正式。
师：哦，正式的，right。And then, opposite to "formal", we say number two, "Hi, can you come to the opening..." It's in an informal tone. What's the meaning?
生：非正式的。
师：Right. And as you can see, informal tone, formal tone. Now, can you guess the meaning of "tone"?
生：语气。
师：Yeah, you know what? Tone is a very, very important point for us to consider when we want to make a proper invitation. Let's learn it from the headmaster's invitation. At the very beginning, he says "I would like to invite you to the opening of our library." Is it proper for him to say "Hi, can you come to the opening of our library?" Is it proper?
