Language is always changing and developing. This isn’t a bad thing. If English hasn’t changed for a long time, we won’t have words to    telephones, washing machines, computers or some other new things.
Language changes for   reasons. First, it changes because the needs of its speaker change. New technologies, new   , 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 _  they have different ages, jobs, educationlevels and so on.

A. shorter    B. another    C. alive    D. communicate with    E. the other

 
How does language develop then? On the one hand, many of the language changes begin with young people. When young people__  others of their own age, their language grows in grammar, words and expressions. Some have a short lifetime but others have a long life. On __ hand, we get new words in many different ways. We borrow them from other languages, we create them by making words  or putting words together and we make them out of proper names.
Languages that don’t change over time are considered dead languages. The fact that English changes so much shows that it is   and well.
