OK, thanks for the comment that makes it clear what you're asking. You can describe many things about a guest - physical characteristics (how tall, hair color, eye color, etc.) but this is pretty boring. It's better to talk about why they came, how you felt about their being there, and what, if anything, occurred later because they came.

why do you have suffer from articulation problem??

Thank you so much for your comment, btw I'm going to post my "preparation" about this topic, plz help me correct it if you are able :>

I would recommend describing your guest: what he/she looks like; where he/she is from; and how you know him/her. Then, tell what makes this guest special to you. Hope that helps! On a side note, it would be better to say, "Please give me at least one idea if you are able." Humans are not described as "possible" in English. Nor is any living thing, actually. We use "possible" to talk about whether something can happen. For example, events or outcomes can happen: a visit is possible; a storm is possible; an infection is possible. This is a very basic overview of how to use "possible"; I'm sure someone could go on and on about how to use it, but I want to spare you ;)

Just imagine any of your relatives or friends visiting your house , and your mum will treat them like special guests . She will make them feel comfortable and cook special food for them on the occasion . She will do anything to make their visit as happy as possible . blah blah .....
