Edexcel English Literature - Extract Analysis help

Hi, so the first Edexcel English Literature exam is on Monday (for me at least), and I'm learning quotations for the 'elsewhere in the play' questions, and where you have to use your own quotations, and I'm doing Romeo and Juliet, and one of the questions is analysing an extract and a question may ask how someone's feelings are presented. So I'm currently practising that, and I know Shakespeare loves to use juxtaposition, similes, metaphors, etc, and I can pick them out, but I never know what to actually say about them. Like what does juxtaposition suggest about feelings or what do I comment on about those language features?

Also, what do I have to say in terms of form and structure as I noticed that was on the mark scheme for a practice paper.

Thanks!
