Languages play an important part in our life. Mother language is a very intimate(密切的)thing to us. For people who speak an ancient tongue as their mother language, it helps them keep their traditions. If you talk to a man in a language he understands, that goes to his head. If you talk to a man in his own language, that goes to his heart.
The associations that lie in the languages bring ideas and pictures to our minds. Associations are just the power of languages. However, how language came into being is unknown. All we know is that some early men invented certain sounds to express thoughts and feelings, actions and things, so that they could talk with each other. Later they agreed on certain signs, which could be put together to show those sounds, and which could be written down. Those sounds, whether spoken or written in letters, are called words
Words become filled with meaning for us by experience; and the longer we live, the more certain words bring back to us the happy and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.
Over the last century, more than 400 languages have died out. Some languages are now spoken only by a few dozens of people. Why are humans speaking fewer languages than we once did? The answer has to do with globalization(全球化). Nowadays, it's more useful to speak certain languages-English is one example-rather than others.
As US writer Rita Mae Brown wrote, "Language is the roadmap of a culture. It tells where its people come from and where they are going." We should learn to choose our words carefully and use them correctly, or they will make ourselves silly and common.
