We need to learn English because it is an international language and we cannot get access to various educational institutes after learning and speaking English.
Because English is the world wide window of communications. This is an international language and we can get all data in the world in English Language. Today in every country English is used in schools, colleges and offices also.
The answer should be easy. English is a universal language (global language in case we are not the only creature who can speak.) The world has changed. We can no longer live alone in our country anymore. If you want to learn the world you need to learn english....
Learning English is one of the best decisions one can make in order to improve their communication skills.
If you have studied an English language course, you have a great addition to your CV, which is likely to impress potential employees! Rather than just a qualification, it gives you the added wow-factor and shows that you are well-travelled and determined.
