We use language every day. We live in a world of words. Hardly

any moment passes with someone talking, writing or reading. Indeed, 【M1】________

language is most essential to mankind. Our life increasingly depends

on fast and successful use of language. Strangely enough, we know more 【M2】________

about things around us than that of ourselves. For example, language is 【M3】_________

species-specific, that is, it is language that differs human from animals. 【M4】_________

However, we do not know yet how exactly we inquire language and how 【M5】_________

it is possible for us to perceive through language; so do we understand 【M6】_________

precisely the relationships between language and thought, language and

logic, or language and culture; still more, how and when language 【M7】_________

started. One reason in this inadequate knowledge of language is that we, 【M8】_________

language users, take too many things for granted. Language comes to

every normal person so naturally that a few of us stop to question what 【M9】_________

language is, much less do we feel the necessity to study it. Language is

far more complex than most people have probably imagined and the

necessity to study it is much greater than some people may have

assumed. Linguistics is a branch of science which takes language like its 【M10】________

object of investigation.
