I recommend the translation of the English self-introduction template for freshmen as follows:

Good Morning, everyone! I'm glad to introduce myself here.

Good morning everyone. I'm glad to introduce myself here.

Although this is the first time for me to introduce myself in English, I believe I can perform well.

Although this is the first time for me to introduce myself in this way, I believe I will have a good performance.

I hope you can remember my name through this simple introduction.

Remember my face, I believe we will become friends in the near future.

I hope that through this simple introduction, more people will know me and remember my appearance. I also believe that we will have a chance to be friends soon.
