"Your friend is handsome, can you introduce him to me?"
This exercise should also accept an answer with an explicit, second "你": "你的朋友很帥，你可以給我介紹嗎？"
I was wondering about that -- would a second 你 sound too formal, or do people indeed talk that way sometimes?
The sentence doesn't say 'very' - I'm not sure if you need it when using 帅
很 doesn't mean "very" here, but it's the alternative to 是 when describing someone using an adjective. Someone had a great example that you use 是 to say "He is my friend", since "my friend" is a noun; but you use 很 to say "He is handsome", since "handsome" is an adjective. I think you could use 是 though to say "He is a handsome man".
