An ancient Chinese proverb once said that "Learning is a treasure that will follow its owner everywhere." Learning a new second language can be one of the best treasures you can ever acquire. English is known to be one of the most used languages ​​in the world. As many of us know, the English language is spoken as a native language by over three hundred million people around the world. It is the official language of many familiar countries such as the United States, Australia, Canada, Great Britain and many others. The process of learning a second language can be difficult, because it requires a great deal of time, energy and dedication; But above all, determination is what matters most in the end. The outcome of learning English will be beneficial only because many official jobs and studies are English-based. As a second language, English is especially necessary for official business, education, information and other activities in many countries. The English language has led Tan, Mukherjee, and Cofer to successful educational careers and I believe it will become a valuable resource for others, including myself. Even if you learn a second language, there is a big chance that you may get confused between your native language and your new language. Regardless of the possibilities of confusion between the two languages, the advantages will only minimize the disadvantages and maximize the advantages. Overall, English holds the largest market in the world. I think people in the United States should speak, read, and write English fluently in order to survive in a foreign country. The fluency of those living in the United States should be about the ability to communicate with each other, because English will not only lead to a... half document ......to find a decent job in the United States or China. As a final point, some might say “What if I understood English? It simply shows that you understand two languages, it doesn't automatically generate money just because you understand two languages." It may be true that simply knowing two different languages ​​will not automatically generate money, but knowing two different languages ​​will certainly increase your chance of getting a better job than someone who only speaks one. Let's just say that one knows only one language, that means he can expand his career only in one place, but if you understand a useful language like English, then it will expand your chances and opportunities in seventy-five other countries besides America. In the end, learning English will only bring benefits to your life and minimize the disadvantages of knowing two languages.
