To complete the dialogue, let's match each part of the conversation with the most suitable phrase from the box:
Maria: Hello, Karl. How are things?
This question is typically used to ask someone how they are doing.
Karl: Not bad, thanks. This is Sam.
Karl introduces Sam by using the phrase "This is Sam."
Maria: Hi, Sam. Good to meet you.
Maria greets Sam and expresses pleasure in meeting him.
Sam: And you. Hey, that's a cool camera. Are you into photography?
Sam notices Maria's camera and asks if she's interested in photography.
Maria: Yes, but I'm not very good at it. What part of Australia are you from?
Maria follows up by asking about Sam's specific location in Australia.
Sam: I'm from Sydney. Maria: That's interesting. See you later then.
Maria concludes the conversation with a farewell.
For the preposition exercise, based on typical usage in English:
Hi! I'm a student at Seaford School.
The word "at" is commonly used to specify the institution you belong to.
I'm really into pop music.
The word "into" is used to express strong interest or enthusiasm.
I like sport and I'm good at hockey.
The preposition "at" is suitable when referring to skills or abilities.
What about you?
"About" is used in this phrase when you're returning a question back to someone.
Send a photo if you've got one.
"If" is used here to refer to a condition (having a photo).
Bye now!
No preposition is needed for the phrase "Bye now," since it stands as a complete expression.
