Why do we have to learn English? My answer is to have an advantage to access to the world. To me, English is not just a language, it also opens new doors to the vast ocean. Firstly, I can get close to international sources of information, online and offline such as articles, books, essays,… Therefore, I can gain a lot of useful knowledge in different fields. Secondly, when you can use English proficiently, there are many jobs you can apply for with a high salary. Working for a multinational company is always my dream. Finally, I also make a lot of new friends from many countries, and they let me know about their different cultures. I have a dream that one day I can travel around the world, and there is no tool which is simple to get and useful to help me achieve that dream like English.
