There are a number of languages spoken throughout the world. Every person knows at least one language, which he learns in his childhood and is routinely used for speaking and writing. However, many people are fond of learning two or more languages, so they try to be bilingual, which means that they try to have the knowledge of two or more languages. And being bilingual can bring a person a number of benefits in various aspects. For example:
A person can get cognitive(认知的) benefits from it. The bilingual people have two or more words for each idea and object. Therefore, a bilingual person can develop a creative thinking. The bilinguals are aware of which language should be spoken with which person in a particular situation. So they are more sensitive(敏感的) to the needs of the listener than the people who only use one language: Being bilingual also improves and enriches a person's mental development.
Being bilingual has a positive effect on a person's character. The bilinguals are able to switch between different languages and talk to different people in various languages. It increases a sense of self-esteem( 自尊). Being bilingual creates a powerful link in different people from different countries.
A bilingual education offers better curriculum(课程) results. The bilinguals tend to show a higher performance in examinations and tests. The bilinguals find it quite easy to learn and speak three, four or more languages.
Being bilingual offers potential employment benefits. It offers a wider choice of jobs in various fields. The bilinguals can get a great many career opportunities in transport, tourism, public relations, marketing and sales, banking, translation, law, teaching and so on.
So it can be concluded from the above that we should try our best to learn and master two or more languages.
