introduce 和 present 的差別在哪裡？如果不好說明，請提供一些例句。

Meaning of introduce: to make one person known to another person by name. We also use this verb with a reflexive pronoun (myself, yourself, himself, etc.) if we are introducing ourselves.

Meaning of present: to formally introduce another person, particularly in a presentation or before an audience.

Example 1:
Ellie is a wonderful hostess. Whenever she has a party, she always makes sure to introduce her guests to each other.

Example 2:
I'm sorry! I haven't introduced myself. My name is Neil Harte and I'm the head of sales here at Rock Investments.

Example 3:
Good afternoon and thank you for coming to the lecture. It gives me great pleasure to present our speaker, Dr. Amanda White.

Example 4:
I'd like to present the winners of this year's Concerned Citizen Award: Richard Holland and Katherine Kahne. Please give them a big hand!
