Topic: My Academic Ambition
参考答案:[参考范文]
My Academic Ambition
With the economic development and globalization, communications among countries are becoming more and more frequent. We are eager to communicate with the outside world to learn advanced technologies, to cooperate with other countries and to build up a friendly relationship with them. So I choose foreign language learning as my academic ambition.
The uses of language can be incarnated in many aspects. When you mastered a foreign language, you would be able to experience first hand the great literature of another peopled you Would experience directly the power and subtleties of the original, which are often lost in translation; you would feel the flow of the language, the combinations of sound and word order, all of which combine to bring the work alive, alive as the artists have intentionally planned.
Furthermore, language exchange is a prerequisite for cultural exchange. To learn another language helps gain knowledge about another culture. Language itself is part of the culture too. Through learning another language, one can not only have a more profound and thorough notion that every country has different customs and cultures but also see that there are other ways to see how men are related to the environment.
With China’s reform and opening up to the outside world, international cultural exchanges are getting more prevalent in every trade and profession. It is enjoyable and useful to learn foreign languages. Therefore, I will persist in my academic ambition and try my best to make it come true.
