电视棒The metalingual function means people can use language to talk about itself. E.g. I can use the word “book” to talk about a book, and I can also use the expression “the word book” to talk about the sign “b-o-o-k” itself.1.6What is linguistics?Linguistics is the scientific study of language. It studies not just one language of any one community, but the language of all human beings.1.7Main branches of linguistics1.7.1PhoneticsPhonetics is the study of speech sounds, it includes three main areas: articulatory phonetics, acoustic phonetics, and auditory phonetics.1.7.2PhonologyPhonology studies the rules governing the structure, distribution, and sequencing of speech sounds and the shape of syllables.1.7.3MorphologyMorphology studies the minimal units of meaning morphemes and word-formation processes.1.7.4SyntaxSyntax refers to the rules governing the way words are combined to form sentences in a language, or simply, the study of the formation of sentences. 1.7.5SemanticsSemantics examines how meaning is encoded in a language.1.7.6PragmaticsPragmatics is the study of meaning in context.1.8MacrolinguisticsMacrolinguistics is the study of language in all aspects, distinct from microlinguistics, which dealt solely with the formal aspect of language system.1.8.1PsycholinguisticsPsycholinguistics investigates the interrelation of language and mind, in processing and producing utterances and in language acquisition for example.1.8.2SociolinguisticsSociolinguistics is a term which covers a variety of different interests in language and society, including the language and the social characteristics of its users.1.8.3Anthropological linguisticsAnthropological linguistics studies the relationship between language and culture in a community.1.8.4Computational linguisticsComputational linguistics is an interdisciplinary field which centers around the use of computers to process or produce human language.1.9Important distinctions in linguistics1.9.1Descriptive vs. prescriptive一、选择题1若是奇函数，则其图象关于（ ）A轴对称B轴对称C原点对称D直线对称2若函数是奇函数，则下列坐标表示的点一定在函数图象上的是（ ） A B C D 3下列函数中为偶函数的是（ ）ABCD4. 如果奇函数在上是增函数，且最小值是5，那么在上是（ ）A增函数，最小值是-5B增函数，最大值是-5C减函数，最小值是-5D减函数，最大值是-5 5. 已知函数是奇函数，则的值为（ ）ABCD6.已知偶函数在上单调递增，则下列关系式成立的是( ) ABCD二、填空题7若函数是奇函数，则的值为_ . 8若函数是偶函数，且，则与的大小关系为_.9已知 是定义在上的奇函数，当 时， 的图象如右图所示，那么f (x) 的值域是 .10已知分段函数是奇函数，当时的解析式为 ，则这个函数在区间上的解析式为 三、解答题11. 判断下列函数是否具有奇偶性： (1)； (2) ；(3)； (4) ； (5) .12判断函数的奇偶性，并指出它的单调区间.13已知二次函数的图象关于轴对称，写出函数的解析表达式，并求出函数的单调递增区间很好的3D电视棒可以看很多高清电视的，而且非常好不用和缓冲。能力题14设是定义在上的偶函数,且在上是增函数,则与（）的大小关系是（ ） ABCD与的取值无关若函数 15已知是奇函数，是偶函数，且在公共定义域上有，求的解析式. 函数的奇偶性答案一、选择题题号123456答案CBCBCC二、填空题 7 8 9 10三、解答题 11(1)奇函数，(2)非奇
