1) I learn English because it is a widely spoken language that opens up opportunities for communication, travel, and career advancement. It is also a language of culture and entertainment that allows me to access a wide range of literature, films, and music.

2) To improve my English, I should practice speaking and listening regularly, expand my vocabulary, work on my grammar and writing skills, and immerse myself in English-speaking environments. Additionally, using language learning apps, taking courses, and seeking feedback from native speakers can also help me enhance my English proficiency.
