Feedback on Chinese Presentation, please?

[Emmaline]

In my chinese class, we're doing a presentation on culture. I'm doing mine on chinese inventions. I want to open and close in Chinese, but I'm unsure about my grammar. Here is what I'm going to say, Feedback would be much appreciated.

 

Beginning: 

 

DàJiā hǎo. Wǒde Míngzi jiào Emmaline. Wǒ Jīntiān gàosù nǐ guānyú zhōngguó de Fāmíng.

Ending:

 

Wǒmén dōu huì tóngyì, zuì hǎo de Zhōngguó de Fāmíng shì yuè bǐng.

 

我们都会同意最好的中国的发明是月饼

 

谢谢你!

@aone's suggestions are good, but I think the grammar and vocabulary in their introduction is quite high-level. Here's how I'd put it myself (disclaimer: not a native speaker):

 

大家好。我的名字叫 Emmaline。我今天要给你们讲告诉你关于中国的发明。
 

……

 

听完了我的演讲，我们大家一定都会同意，中国最好的中国的发明就是月饼！
 

谢谢你大家。

 

Remember when you're adressing an audience of more than one person, you can't call them “你”, it has to be “你们” or “大家”. Also, of course it makes no difference when you're speaking, but remember that Chinese text uses Chinese punctuation (。，！？ rather than .,!?).

 

我不同意你的结论，月饼好难吃啊！中国最好的发明就是……微信（WeChat）！
