Are you going to the post office? Could you send this letter for me?
I'm walking my dog so I can walk your Rex,too.
Are you driving? Can you give me a lift?
I'm going shopping. Would you like me to get you anything?
Can I use the computer? I"d like to send a few e-mails.
I'm going to see the head teacher this afternoon. Shall I mention the problems with the canteen?
