Why is there such a position?

The most important thing is the development of English. 1688, the "glorious revolution" broke out in Britain and a constitutional monarchy was established. Under such political conditions, the economy also has good conditions for development. In the middle of the 18th century, the first modern science and technology took place, and Britain took the lead in realizing the transformation from an agricultural economy to an industrial economy. As a result, the national strength increased greatly and colonialism was vigorously promoted abroad. In this case, English began to become the official language and mother tongue of many colonies. Coupled with the rise of the United States, it has boosted the development of English. The United States became the world hegemon in the 20th century, which had a great influence on the world structure. Therefore, the United States, whose mother tongue is English, naturally pushed the influence of English to a higher level. The globalization of information and economy has also enhanced the influence of English. The common language of the Internet is English, and more than 95% of Internet information is provided in English. The development of information technology has consolidated the position of English as the first language in the world. English is also the dominant language in aviation, finance, science and technology. This is why English has such a position.
