We use language primarily as a means of communication with (来源：英语杂志 http://www.EnglishCN.com)

other human beings. Each of us shares with the community in which we

live a store of words and meanings as well as agreeing conventions as  (1)

to the way in which words should be arranged to convey a particular (2)

 message: the English speaker has iii his disposal at vocabulary and a (3)

set of grammatical rules which enables him to communicate his (4)

thoughts and feelings, ill a variety of styles, to the other English (5)

speakers. His vocabulary, in particular, both that which he uses active-

[y and that which he recognises, increases ill size as he grows

old as a result of education and experience.                  (6)

But, whether the language store is relatively small or large, the system

remains no more, than a psychological reality for tike inpidual, unless

he has a means of expressing it in terms able to be seen by another (7)

member of his linguistic community; he bas to give tile system a

concrete transmission form. We take it for granted rice’ two most (8)

common forms of transmission-by means of sounds produced by our

vocal organs (speech) or by visual signs (writing). And these are (9)

among most striking of human achievements.               (10)
