I did a quick research from wiki to try and give you some ideas, Hassan. You could talk about how English is one of the official languages in Pakistan and in the courts, English is the official language. At college and universities most instruction is in English. Most major papers also have an English edition and so many people see politics/daily events through an English 'filter' or influence. You could also talk about how a lot of people mix a lot of English words in their conversation - even if they can't speak English, itself. And some with more knowledge of English, mix this language with another even in the same conversation. Also every language adopts/takes up words and expressions from other languages. Maybe talk about some of these that you are aware of. These are just some ideas you could expand on.
