Shall I take my favorite books? - Of course, it's a very good idea!
Shall I take guitar? - Do, Please, it's a very good idea!
Shall I help you to prepare for the trip? - No, thank you!
Shall I take a swimming costume? - I am afraid you don't have to.
Shall I learn a popular song? - I'm sorry you needn't...
Shall I take some money for souvenirs? - I'm afraid you can't.
Думаю это все.
