The Future of Chinese

As we all know, there are many languages in the world, and different countries have different languages as their mother languages, such as Chinese, English, Russian and French. Chinese, which can be dated back to thousands of years ago, is widely spoken in the world, and will have a bright future, acting a more and more important role on the world stage. The reasons are as follows.

First of all, Chinese characters are a kind of writing in pictures, which are easy to learn and memorize. Second, compared with other languages, Chinese has much emotional colouring, including happiness, anger, sadness and pleasure. There are many words and expressions for choices to express different feelings.

Third, taking up one-fifth of the world’s population, China will have more and more effect on the world in all kinds of fields, like politics, economy and culture. China will become the centre of the world. And certainly Chinese, as the mother language of it, will be used more and more often. From a long run, Chinese will have a bright future and have the opportunity to be the world language.

1. Retell the passage: Who owns English?
