Ⅲ型观测线
A．近缺牙区的倒凹区小，非倒凹区大，而远缺牙区的倒凹区大，非倒凹区小
B．近缺牙区的倒凹区大，非倒凹区小
C．倒凹区与非倒凹区均大
D．倒凹区均大，非倒凹区均小
E．倒凹区均小，非倒凹区均大
参考答案：D
解析： Ⅰ型观测线近缺牙区的倒凹区小，非倒凹区大，而远缺牙区的倒凹区大，非倒凹区小。Ⅱ型观测线与一型观测线相反，近缺牙区的倒凹区大，而非倒凹区小。Ⅲ型观测线在近缺牙区或远离缺牙区均离面近，离龈方远，故倒凹区均大，非倒凹区均小。
| Every group has a culture, however uncivilized it may seem to us. To the professional anthropologist, there is no intrinsic superiority of one culture over another, just as to the professional linguist, there is no intrinsic hierarchy among languages. People once thought of the languages of backward groups as undeveloped. While it is possible that language in general began as a series of grunts and groans, it is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex. They differ from Western languages not in their sound patterns or grammatical structures, which usually are fully adequate for all language needs, but only in their vocabularies, which reflect the objects and activities known to their speakers. Even in this aspect, two things are to be noted. First, all languages seem to possess the machinery for vocabulary expansion, either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. Second, the objects and activities requiring names and distinctions in "backward" languages, while different from the West, are often surprisingly numerous and complicated. A Western language distinguishes merely between two degrees of remoteness ("this" and "that"). But some languages of the American Indians distinguish between what is close to the speaker, or to the person addressed, or removed from both, or out of sight, or in the past, or in the future. |
