The Vieira family moved to the United States in 1981.At that time, they decided to stop speaking Spanish at home and only communicate in English.This was because they were now living in an Englishspeaking country.
Now the Vieira children are adults, and they sometimes travel to Spain to visit their family and friends.But they can't communicate with them.Unfortunately this is common.When people move to new countries, they often leave their own customs and mother language behind.This is a mistake because there are many benefits to knowing more than one language.
One advantage of speaking more than one language is that you can communicate with more people around the world.You don't have to depend on others to talk for you, so you are more independent.People who know only one language must use others to help them communicate.
Furthermore, speaking the second language also allows people to experience other cultures and customs more effectively.Local expressions, vocabulary, and even jokes can have a powerful effect on a person's understanding of other culture.So knowing more than one language increases your knowledge of other cultures.
Finally, having more multilanguage speakers improves relationships between countries.If people from different countries can communicate well, the world can become closer.Countries will then have more respect for each other and better understand each other's problems.
The benefits of knowing more than one language are clear.In fact, there are no disadvantages.It is very sad that many people don't try to learn another language.It's even worse when people let themselves forget their mother language and become silenced.
