For language analysis, I like to analyse language for fun. For example, your mum might be speaking to you. You can analyse her words by asking yourself: "What is her contention?", "what is her tone of voice?", things like that. Form quick statements of analysis then colour it with good vocabulary and concise and coherent sentences.
For context, ponder over things. E.g. "Conflict is never fair". Keep this topic in your mind, be aware of how conflict arises within your everyday life and how the people involved are consequently affected. (Just an example, tailor it to the context you're doing). Also read and annotate the texts for it.
For text response, read the text (as you've done), and annotate. Then, explore. I'd suggest putting yourself into the eyes of the characters in the book/play/movie. If it's a movie, explore the film techniques: mis-en-scene, lighting, contrast, sounds, camera angles, size, etc.
For each, look at the sample prompts and articles from past examples then meditate over them. Perhaps even have a go at them when you feel like it. These should point you in the direction of how you should be thinking about each area in English.
