Why is it important to learn English?
There are many, many reasons

why learning a new language is a good idea. It allows you to communicate with new people. It helps you to see things from a different perspective, or get a deeper understanding of another culture. It helps you to become a better listener. English is the rest of the world’s “second language”. While Mandarin and Spanish are the mother tongues of more people overall, most people in the world choose to learn some English after their native language. In fact, one in five people on the planet speak or understand at least a little bit of English.
This makes English one of the most useful languages you can learn. After all, you can’t learn all 6,500 languages in the world, but at least you will be able to communicate with people from all different countries using English.
