People thinking about the origin of language for the first time usually arrive at the conclusion that it developed (31) as a system of grunts, hisses and cries and (32) a very simple affair in the beginning. (33) , when we observe the language behavior of (34) we regard as primitive cultures, we find it (35) complicateD、It was believed that anEskimo must have the tip of his tongue a vocabulary of more than 10,000 words (36) to get along reasonably well, much larger than the active vocabulary of a (n) (37) businessman who speaksEng-fish. (38) , theseEskimo words are far more highly inflected (词尾变化的) than (39) of any of the well-knownEuropean languages, for a (40) noun can be spoken or written in (41) hundred different forms, each (42) a precise meaning different from that of any other. The forms of the verbs are even more (43) . TheEskimo language is, (44) , one of the most difficult in the world to learn, (45) the result that almost no traders or explorers have (46) tried to learn it.Consequently, there has grown up, in communication betweenEskimos and whites, a jargon (47) to the pidginEnglish used in OldChina, with a vocabulary of from 300 to 600 uninflected words. Most of them are (48) fromEskimo but some are derived fromEnglish,Danish, Spanish, Hawaiian and other languages. It is this jargon (49) is usually referred to by travelers (50) "theEskimo language".
