Some Things We Know about Language Many things about language are a mystery, and many will always remain so. But some things we do know. First, we know that all human beings have a language of some sort. There is no race of men anywhere on earth so backward that it has no language, no set of speech sounds by which the people communicate with one mother. Furthermore, in historical times, there has never been a race of men without a language. Second, there is no such thing as a primitive language. There are many people whose cultures are undeveloped, who are, as we say, uncivilized, but the languages they speak are not primitive. In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood; indeed, the direct contrary has often been stated. Popular ideas of the language of the American Indians will illustrate. Many people have supposed that the Indians communicated in a very primitive system of noises. Study has proved this to be nonsense. There are, or were, hundreds of American Indian languages, and all of them turn out to be very complicated and very old. They are certainly different from the languages that most of us are familiar with, hut they are no more primitive than English and Greek. A third thing we know about language is that all languages are perfectly adequate. That is, each one is a perfect means of expressing the culture of the people who speak the language. Finally, we know that language changes. It is natural and normal for language to change; the only languages which do not change are the dead ones. This is easy to understand if we look backward in time. Change goes on in all aspects of language. Grammatical features change as do speech sounds, and changes in vocabulary are sometimes very extensive and may occur very rapidly. Vocabulary is the least stable part of any language.
A. just as old as some well-known languages B. just as sophisticated as some well-known languages C. more developed than some well-known languages D. more complex than some well-known languages

刘某从百货商店购买了一台电扇,回家后高高兴兴地装好电扇,刚一打开电扇,不料电扇漏电,将刘某击倒在地,不省人事。家人立即将刘某送往医院,经过三个多月治疗,刘某才出院。为此,刘某要求商店和电扇生产厂家赔偿经济损失。但商店认为自己只负责卖货,不负责质量;电扇厂家则认为电扇出厂时有合格证明,出厂后的质量问题应由商店负责。刘某的损害赔偿问题,像个皮球被生产者和销售者踢来踢去,一拖就是一年。无奈之下,刘某诉诸法院。本案中,谁应当对该电扇的质量负责?
