Can you tell your friend where the shop is?

[dwni1]

I want to ask if the imperative form of sentence have a request alternative and if they impact the structure of the sentence.
For instance, I use these imperative sentences.

1 Tell your friend where the shop is.
2 Show your colleague how to work faster.
3 Tell your friends to come with us to the party.
3 Ask your friends if they want to come with us to the party.
4 Stop running so fast.

Can I use all these sentences in request form with can and could?

For example,

1 Can you tell your friend where the shop is?
2 Can you show your colleague how to work faster?
3 Can you tell your friends to come with us to the party?
3 Can you ask your friends if they want to come with us to the party?
4 Can you stop running so fact?

Yes, they're possible with either 'can' or 'could'. You could also make them requests with 'would'.

Are the imperative versions possible?

 

[Tarheel]

They are all possible. (That doesn't mean you should use them.) Also, some of them are more natural than their "request" versions. For example, "Stop running so fast!" (#5) is something you might say to a four-year-old who is running around and not looking where she's going.
