Language is always changing and developing. This isn’t a bad thing. If English hadn’t changed for a long time, we won’t have words to describe telephones, washing machines, computers or some other new things.
Language changes for several reasons. First, it changes because the needs of its speaker change. New technologies, new products, and new experiences need new words to express them clearly. Another reason for change is that different people have different language experiences. People use different sets of words and expressions, because they have different ages, jobs, education levels(水平) and so on.
How does language develop then? On the one hand, many of the languages changes begin with young people. When young people communicate with others of their own age, their language grows in grammar, words and expressions that are different from the older people’s. Some have a short lifetime but others can influence the language for long. On the other hand, we get new words in many different ways. We borrow them from other languages, we create them by making words shorter or combining words and we make them out of proper names.
