At noon this Friday, I will be invitedgiving a speech as athe master of ceremonies at the wedding ceremony of one of my classmate's sons to give a speech.

First of all, I will give people who attend the wedding,wedding guests and the bride and bridegroom warm greetings.

Second, I will give an introduction toe the bride and bridegroom, and the processshare the story of their relationship.

Third, I will giveshare my wishes for the bride and bridegroom some wishes, for example, wish. For example, I will wish for them to get along with each other, wish them to treat their parents and relatives well, wish them to work hard and study hard, and so on.

In short, I will wish all the best for them.

At the end of the speech, I hope peoplwill encourage wthose attending the wedding to have a good time.

Your sentence here is a little ambiguous. Are you talking about how you will end the speech? If so, what I wrote is fine. If you are talking in general about hoping people have fun after your speech is over, you can say, "I hope that the guests/those attending the wedding will have a good time after my speech is over."

I wrote the speech by myself, and I read it as many times as long as I had timeI could.

Instead of "read", "practiced" would also work fine here.

I want to give a good performance at the wedding to thankrepay my classmate's trust in me.

So, I have tried to give the speech without manua script many times, but I felt it was so difficult for me because of my bad memory.

If I can't do that at the wedding, I think just reading the manuscript may not be a bad thing I think.
