Section B Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice. Every profession or trade, every art, and every science has its technical vocabulary. Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other vocations, like fanning and fishery, that have occupied great numbers of men from remote times, the technical vocabulary, is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very fiber of our language. Hence, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technicalities. The special dialects of law, medicine, divinity, and philosophy have also, in their older strata, become pretty familiar to cultivated persons and have contributed much to the popular vocabulary. Yet every vocation still possesses a large body of technical terms that remain essentially foreign, even to educated speech. And the proportion has been much increased in the last fifty years, particularly in the various departments of natural and political science and in the mechanic arts. Here new terms are coined with the greatest freedom, and abandoned with indifference when they have served their turn. Most of the new coinages are confined to special discussions, and seldom get into general literature or conversation. Yet no profession is nowadays, as all professions mine were, a close guild(行会). The lawyer, the physician, the man of science, the divine, associated freely with his fellow-creatures, and does not meet them in a merely professional way. Furthermore, what is called 'popular science' makes everybody acquainted with modem views and recent discoveries. Any important experiment, though made hi a remote or provincial laboratory, is at once repotted in the news papers, and everybody is soon talking about it as in the case of the Roentgen rays and wireless telegraphy. Thus our common speech is always taking up new technical terms and making them commonplace. Special words used in technical discussion ______.
