Teacher: Hi class. I'd like to introduce an exchange student who comes from New York. Welcome Jack!
Students: Hello, Jack. Nice to meet you.
Jack: Nice to meet you all. This is my first time in Viet Nam.
Teacher: Now you can ask Jack any questions you would like to ask.
Phong: Do American students wear school uniforms every day, Jack?
Jack: No, most American students don't wear school uniforms. Most students at my school wear pants and T-shirts.
Phong: What do you mean by 'pants', Jack?
Jack: Ah, I mean trousers. In American English, 'pants' mean 'trousers'.
Phong: I see.
Teacher: Yeah, there are some differences in vocabulary between American English and British English. Are there any more questions?
Mi: Yes. I want to know about the students in your school. Are all of you American? And do all of you speak English?
Jack: Good question. Most of us are American, but some are immigrants from other countries like Viet Nam, India, and Mexico. Their first language is not English, but they all speak English at school.
Mi: That's interesting!
