Analysing Grammar structures

[Michaelpp]

I am having difficulties trying to understand this question, any help or advice would be appreciated.

Write the form, function and phonological aspects of these items.

I was having a bath when the phone rang.

I wish I had worked harder.


Many thanks,

Mike

I wish I had worked harder.

A complex sentence with an object clause.
I wish - main clause.
