若妳的這次報告很重要, 或是對象是熟悉英文ㄉ人, 這些用法就不恰當ㄌ...

我建議第一句妳只要說明妳英文不是妳ㄉ母語即可...若要再委婉一點可說...
Before the presentation, I`d like to warn everybody that english is my my native tongue(first language). But I will try to do my best.

第三句
That`s all for my today`s presentation. Thank you all for listening.
我今天報告的主題是...
Today, I`d like to talk about....
或是
Today, the subject of this presentation is to talk about...
