1Introduction

The advent of integral-?eld spectrographs has opened a whole new window of pos-sibilities for extra-galactic studies.Coupled with large telescopes and advances in adaptive optics systems(AO),integral-?eld units(IFUs)offer a unique opportunity to go further in the exploration of astrophysical phenomena earlier in the history of the universe and at smaller scales.It is therefore not surprising that IFUs are quickly becoming standard instruments on all the8m-class telescopes.Besides the efforts to investigate the formation and evolution of galaxies in the early universe,much can be learned by studying in detail the fossil record of nearby galaxies using IFUs on intermediate-size telescopes.The SAURON project(de Zeeuw et al.2002),is a ?rst step in this direction.The project is designed to perform a systematic study of a representative sample of early-type,nearby galaxies using the SAURON(Bacon et al.2001)and OASIS(Bacon et al.1995;McDermid et al.2004)IFUs at the4.2m William Herschel Telescope.Early results of the survey have revealed a variety of structures much richer than usually recognised in early-type galaxies(de Zeeuw et al.2002;McDermid et al.2004;Emsellem et al.2004;see also R.McDermid’s contribution in this workshop).

Here we focus on the distribution and kinematics of the ionised gas of a subset of galaxies to illustrate the diversity of structures and ionisation processes present in the SAURON representative sample of48elliptical and lenticular galaxies.The sample contains an equal fraction of elliptical and lenticular galaxies,with equal number of?eld and cluster galaxies in each morphological group.We will make use of the two-dimensional information delivered by SAURON to compare the dis-tribution and kinematics of the stars and gas and to study the nature and origin of the ionised gas in these systems.A more extended analysis of the properties of the ionised gas for the entire sample is presented in Sarzi et al.(2005).Furthermore,the study of the stellar and gas properties of the24Sa bulges in the SAURON sample is addressed in Falc′o n-Barroso et al.(2005).

2Extraction of the ionised gas

Early-type galaxies were traditionally thought to be uniform stellar systems with little or no gas and dust.However,a considerable number of imaging and spec-troscopy studies have changed this view(Sadler&Gerhard1985;van Dokkum& Franx1995;Goudfrooij1999;Tran et al2001).In the spectral range delivered by SAURON there are three potential emission lines that can be measured(i.e.Hβ, [O III]λλ4959,5007,[N I]λλ5198,5200).Given that the stellar contribution to the overall spectrum in our sample of galaxies remains signi?cant,it is important to perform an accurate continuum subtraction in order to determine reliably the?uxes and kinematics of the emission lines.We investigated several methods to perform

this task and settled on a procedure that simultaneously?ts both the stellar and gaseous contributions to derive the?uxes,velocities and velocity dispersions of the emission lines.

Traditional methods to separate the stars and gas consisted of the subtraction of the best matching stellar template,in the regions free of emission,to the full spectrum of the galaxy.As described in Sarzi et al.(2005),this methodology can signi?cantly overestimate the?ux and velocity dispersion of the measured emission lines.Exten-sive simulations show that the new procedure is much more accurate and appears to be superior to previous ones,allowing us to detect emission down to an equivalent width of0.1?A.

3Distribution of the ionised gas

The distribution of the ionised gas in our sample shows diverse morphologies.In general the distribution follows that of the stars,although there are several cases where the situation is much more complex(i.e.?laments,rings,spiral arms,lanes). The incidence of ionised-gas emission in our sample is75%.Seven galaxies show only weak traces of emission,and there are?ve cases with no detection.By mor-phological type,lenticular galaxies display a slightly higher content of ionised gas than elliptical galaxies(83%versus66%).Similar percentages were found when the sample was divided according to environment(83%?eld,66%cluster).One important remark is that the fraction of galaxies with clearly detected emission in the Virgo cluster drops to only55%(10/18),with just3/9ellipticals showing the presence of gas.The incidence of ionised-gas shows no correlation with either lu-minosity or the presence of a bar in the galaxy.The detection rates found for our sample are in good agreement with those of Macchetto et al.(1996),who found emission in85%of the lenticular and68%of the ellipticals in their sample.

In Figure2,we present maps of the stellar and ionised-gas distribution and kine-matics for four of the48galaxies in our sample.NGC2974reveals a fast rotating gas disk co-rotating with respect to the stars.Despite the regular appearance of the ionised-gas distribution,the equivalent width(EW)map of the[O III]line(see Fig.2)highlights the presence of an inner ring and two spiral arms that extend all the way out to the limits of our?eld-of-view(see Krajnovi′c et al.2005a for a de-tailed analysis of this galaxy using SAURON data).A similarly regular case is that of NGC4526,although in this case the ionised gas is con?ned to a well de?ned, fast rotating disk in the central kpc of the galaxy.NGC2768is a well-known galaxy where the distribution of the ionised-gas appears to be perpendicular to that of its stellar counterpart(i.e.polar-ring,Fried&Illingworth1994;Bertola et al.1992). The SAURON[O III]EW map shows that the gas distribution has a?lamentary mor-phology along the galaxy minor axis.The gas distribution in NGC4278displays a

peculiar integral-sign pattern that is closely followed by the gas velocity?eld.The stellar and gas kinematics appear to be misaligned by increasingly wider angles,as they twist in opposite directions towards the outer parts of the?eld-of-view.

4What powers the observed nebular emission?

Diagnostic diagrams of[O III]/Hβvs[N II]/Hα(Veilleux&Osterbrock1987;Kauff-mann et al.2003)have been used extensively in the past to investigate the trigger of the ionisation of the gas(i.e.AGN,star-formation).Many scenarios have been invoked to explain the presence of ionised gas in early-type galaxies:central AGN, hot(107K)gas(Sparks et al.1989;de Jong et al.1990),young stars(Shields1992), post-AGB stars(Binette et al.1994),or shocks(Dopita&Sutherland1995).Within the wavelength range delivered by SAURON only the Hβand[O III]lines can be used for this purpose.Despite this limitation,the[O III]/Hβratio serves as a good indicator to locate regions where emission is due to young stars and also to trace variations of the ionisation mechanisms within a single galaxy.

Regions displaying low[O III]/Hβratios(i.e.≤1)are usually interpreted as indica-tive of star-formation(Ho et al.1997).However,higher ratios(i.e.>1)could still indicate star-formation if the metallicity of the gas is suf?ciently high(Veilleux& Osterbrock1987).Additionally other mechanisms can lead to high ratios.Since it is unlikely that the metallicity of the ionised gas varies abruptly within galaxies(un-less there has been some recent accretion of material),large variations across maps of the[O III]/Hβratio are more likely to be produced by changes in the ionisation mechanism rather than changes in the metallicity.

Figure2shows the[O III]/Hβratios for the galaxies discussed in Section3.The [O III]/Hβratio maps clearly reveal the presence of radial gradients and substruc-tures in the ionisation properties of the gas in the four galaxies.The ratio is mod-erately high in NGC2768,NGC2974,and NGC4278,while it is very low in NGC4526.In this last galaxy,the location of the low[O III]/Hβvalues corresponds to the location of a prominent dust disk(as shown in the unsharp-masked image), and suggests ongoing star formation.In this respect,there seems to be a clear link between the ionised structures found in the[O III]/Hβmaps with those seen in the [O III]equivalent width and kinematic maps(i.e.ring in NGC2974,or integral-sign pattern in NGC4278).

The remaining sample of44galaxies also displays a great diversity of[O III]/Hβratios within galaxies,but also across the sample.This suggests that either there are many mechanisms at play in the ionisation of the gas,that the metallicity of the ionised gas is very heterogeneous in those galaxies,or both.

5Relation between gas and dust

In order to study the dust distribution and compare it with that of the ionised gas we have generated unsharp-masked images using archival Hubble Space Telescope images.We found that,consistent with previous results,dust generally follows the ionised-gas distribution(Goudfrooij et al.1994;Tomita et el.2000;Tran et al. 2001).The opposite situation is not always true,as we have found galaxies with clear presence of emission with no traces of dust in the unsharp-masked images. As found by previous authors(Ho et al.2002),regular dust distributions generally are associated with smooth velocity?elds,however the lack of regular dust lanes does not imply the presence of irregular kinematics.

The four cases presented in Figure2display a wide range of dust morphologies that correlate in different degrees with the structures seen in the distribution of the ionised gas.The prominent dust disk in NGC4526traces closely the distribution of the gas.The ring-like structure and spiral arms in NGC2974are also followed by dusty structures at the same locations.The dust morphology is less de?ned in NGC2768and NGC4278,but still suggests an orientation for the dust that is sim-ilar to that of the gas distribution.

6The Origin of the ionised gas

The measurement of misalignments between the kinematics of the gaseous and stel-lar components in early-type galaxies has often been used to determine the relative importance of accretion events and the internal production of gas through stellar mass-loss(e.g.Bertola et al.1992).The orientation of the dust relative to that of the stars has also served this purpose(e.g.van Dokkum&Franx1995).In order to quantify the presence of decoupled gaseous components in our sample and to inves-tigate their dependence on environment,we have measured the mean misalignment between the stellar and ionised gas using kinemetry,a generalisation of surface photometry to the higher-order moments of the line-of-sight velocity distribution of galaxies(Krajnovi′c et al.2005b).

In Figure2(solid line)we show the distribution of the average misalignments for the galaxies in our sample of48galaxies with suf?ciently extended emission.The distribution of values appears to be skewed towards small misalignments.How-ever,the fact that there is still a signi?cant fraction of galaxies showing mild to strong misalignments suggests that the ionised gas has not a purely internal origin (in which only small misalignments are expected).The overall shape of the distri-bution remains unchanged when the sample is divided into elliptical and lenticular galaxies.No dependency is found on neither environment nor galaxy luminosity. We do,however,?nd a strong dependence on apparent?attening of the galaxy

Fig.1.SAURON maps for4galaxies representative of the gas properties in the48E and S0galaxies surveyed by the SAURON project(Sarzi et al.2005).From top to bottom:i) the reconstructed total intensity,ii)the stellar velocity,iii)the ionised-gas velocity,iv)the equivalent width of the[O III]emission line in?A(in log units),v)the value of the[O III]/Hβratio(also in log units),and vi)unsharp-masked images obtained from HST observations. The cuts levels are indicated in the box at the right-hand side of each map.The grey boxes on the top?gures indicate the?eld-of-view of the HST images in the last row.Notice how the gas distribution can vary from galaxy to galaxy,and how the kinematic major axis of the ionised gas deviates from that of the stars.The[O III]/Hβratio maps clearly reveal the presence of radial gradients and substructures in the ionization properties of the gas.The low[O III]/Hβvalues corresponding to the dust disk in NGC4526suggest ongoing star formation.

(see Fig.2,bottom panel).It appears that the distribution of misalignments of the most?attened objects accounts for the observed excess of co-rotating over counter-rotating gas and stellar systems in the whole sample.The roundest objects(?<0.2) display a more uniform distribution.This result suggests that rotational support might be important to explain the observed dependence.

7Concluding remarks

We have presented some examples of the morphological and kinematical state of the ionised gas in a representative sample of early-type galaxies using data from the SAURON spectrograph at the 4.2m William Herschel Telescope.The results of our analysis reveal a wide range of morphological,but also kinematical structures.It also shows that there must be several mechanisms responsible for the ionisation of the gas,not only across galaxies,but also within galaxies.The presence of dust is common in our sample and is usually accompanied by gas emission.Finally,we studied the distribution of misalignments between the stars and gas in our sample,and conclude that the origin of the ionised gas cannot be purely internal or external.

Various Approaches to Morphology The grammatical description of many, if not all, languages is conveniently divided into two complementary sections: morphology and syntax. Morphology accounts for the internal structure of words. In linguistics, morphology is the identification, analysis and description, in a language, of the structure of morphemes and other linguistic units, such as words, affixes, parts of speech, intonation/stress, or implied context.It also explores the internal structure of words,and the rules by which words are formed.In this passage, I illstrate morphology in several aspects,from the inside formation , the rules of formation.and the main branches of morphology. Many people think of words as the basic meaningful elements of language ,many words can be broken down into still smaller units,called morphemes. Morphemes serve different purposes. Some derive new words by changing the meaning or the part of speech,others only refine and give extra grammatical information about the already existing meaning of a word. As morphemes are pairings of sounds with meanings,there are many complexiities involved, forming a new field by the mane morphophonology. Words could be analyzed into smaller components as they are formed by smaller units. Such as chairman,it is made up of chair and man ,words like boys ,checking ,and disappointment can likewise be further analyzed. They are each made up of boy and –s ,check and –ing ,and dis-. Appoint, and – ment. These smaller compoents are known as morphemes. But they themselves cannot be further analyzed. Chair could not be analyzed into ch and air .There are no relations between the parts ch ,air and the whole chair. Another example, the word ―unacceptability‖ can be divided into un-, accept, abil-, and -ity (abil- being a variant of -able). Of these, at least three are minimal grammatical units, in the sense that they cannot be analyzed into yet smaller grammatical units—un-, abil-, and ity. So morpheme is the smallest unit of language in terms of the relationship between expression and content, a unit that cannot be divided into further smaller units without destroying or drastically altering the meaning ,whether it is lexical or grammatical. Although I have mentioned above that morphemes are the smallest units of language in the certain situation. It self could be sub-classified into different types, depending on different criteria. (1)Free morpheme and bound morpheme An important concept in grammar and, more particularly, in morphology is that of free and bound forms. A bound form is one that cannot occur alone as a complete utterance (in some normal context of use). For example, -ing is bound in this sense, whereas wait is not, nor is waiting. Any form that is not bound is free.Those appear alone, or which may make up words by themselves ,are free morphemes, such as apple,open are free morphemes, or mono-morphemic words. And we could simply say that all mono-morphemic words are free morphemes. Moreover, poly-morphemic words, which consist wholly of free morphemes are called compound, such as headmaster, silkscalf. In contrast, -s in words , ad in adhere must appear with at least another morpheme are called bound morphemes. (2)Root ,affix and stem. We have met poly-morphemic words in the paragraphs mentioned above. In this section ,they ,other than compounds ,can be divided into roots and affixes. Root is the base form of a word that cannot be further be analyzed without destroying its meaning. In other words, it is that part of the word that is left when all the affixes are removed. While the affix is the collective term for the type of morpheme that can be used only when added

语言学纲要名词解释 导言 1.语言学:以语言作为专门研究对象的一门独立学科,其主要任务是研究语言的性质、结构和功能,通过考察语言及其应用的现象,来解释语言存在和发展的规律。 2.语文学:指19世纪历史比较语言学之前的语言研究,这时的语言研究尚未独立,语言学作为其他学科的附庸而存在,语言研究的主要目的是为了阅读古籍和语言教学,从而为统治者治理国家或为其他学科的研究服务。 3.小学:中国传统的语文学,由于汉语书面语使用的文字——汉字的特点,中国传统语言研究抓住汉字,分析它的形体,探求它的古代读音和意义,形成了统称“小学”的文字、音韵、训诂之学,也就是中国传统的语文学。 4.理论语言学:也称普通语言学,是关于语言的一般规律的理论研究。理论语言学的水平在很大程度上决定于具体语言学的研究成果。 5.共时语言学:以同时的、静态的分析方法,研究语言相对静止的状态,描写分析语言在某一时期、某一阶段的状况,是从横的方面研究语言。 6.历时语言学:研究语言发展的历史,观察一种语言的各个结构要素在不同发展阶段的历史演变,是从纵向的方面研究语言的历史。涉及到一种语言的叫做历时语言学,如历史语音学,历史词汇学,历史语法学等;涉及到多种语言和方言的叫做历史比较语言学。 7.索绪尔:瑞士语言学家,现代语言学的奠基人,结构主义语言学的开创者,著有《普通语言学教程》,被人们誉为“现代语言学之父”。他提出语言是符号体系;符号由能指所指两部分构成,这两部分的关系是任意的,一旦形成以后又是约定性的;符号系统内部存在“组合关系”和“聚合关系”;区分了“语言”和“言语”;“内部语言学”和“外部语言学”;“历时语言学”和“共时语言学”。他的学说标志着现代语言学的开始,在不同的程度上影响着20世纪的各个语言学派。 8.布龙菲尔德:美国描写语言学派的代表人物,它的主要贡献是将语言学从哲学理念建设成为一门科学。早期的著作是出版于1914年的《语言研究导论》,立足于心理学来阐释语言、刺激—反应论来解释语言的产生和理解的过程。1933年他的最有影响的著作《语言论》出版。这时,他已经从构造心理学转到行为心理学。他在该书中提出了美国结构语言学派研究语言的基本原则和描写语言结构的总框架。 9.乔姆斯基:转换生成语法的创始人,著有《句法结构》。最出他用结构主义的方法研究希伯来语,后来发现这种方法有很大的局限性,转而探索新的方法,逐步建立了转换生成语法,1957年出版的《句法结构》就是这一新方法的标志。这种分析方法风靡全世界,冲垮了结构语言学的支配地位,因而被人们成为“乔姆斯基革命”,对语言学的发展方向产成了巨大影响。 10.韩礼德:英国语言学家,功能主义语言学派的代表人物,继承了以弗斯为首的伦敦学派的基本理论,并吸收布拉格学派和哥本哈根学派的某些观点的基础上发展起来和创立了系统功能语法,著有《普通语言学教程》《语法功能论》等著作。他从人类学和社会学的角度出发研究语言与社会的关系,把语言看做“社会符号”,其包括功能系统、层次和语境等概念,在语法中认为系统中存在连锁系统和选择系统,在功能语法中他用功能的配置来解释语法结构,提出了概念功能、人际功能、语篇功能。20世纪70年代后,他将注意力转移到语言与社会学、符号学的关系上,对社会语言学进行研究。 11.赵元任:字宣仲,江苏常州人,生于天津。赵元任是“中国语言学之父”。他将科学运用于语言学研究的结果:用自然科学中的基本概念说明语言问题;用自然科学的先进成果记录和分析语音;把自然科学中的研究方法引入语言学;引入科学的描述事物的方式以及解决问题的程序等等。中国的传统语言学在他和同时代的一批学者的努力下,逐步走向现代化。 12.历史比较语言学:出现于18世纪末19世纪初,中心在德国。该学派采用历史比较的方法,通过语音和词形的比较研究语言的发展和演变,发现了语言之间的亲缘关系并建立了语言的谱系分类。历史比较语言学的兴起,是语言学成为一门独立的学科。经过一个多世纪的探索研究,弄清了世界上很多语言的同源关系,建立了世界语言的谱系分类,为语言学的发展做了很大贡献。历史比较语言学也有局限:他强调了语言的历史比较,忽视了语言的共时研究;孤立地研究语言单位,缺乏对语言系统性的研究。 13.结构主义语言学:1916年索绪尔的《普通语言学教程》标志着结构主义语言学的诞生。索绪尔语言理论的核心是语言是符号系统,突破了历史比较语言学的局限,开拓了语言研究的新领域,给语言学带来革命性的变化。

导言 一,名词解释(分,每小题分) ,研究语言的本质,语言的结构和发展规律. .指我国传统的语文学,包括文字学,音韵学,训诂学三方面的内容. ,个别语言学,以一种(或几种有联系的)语言为研究对象,研究某一种语言的结构. ,静态分析的方法,研究语言相对静止的状态,描写分析语言在某一个时期,某一个阶段的状况,是从横向的方面研究语言. ,动态的角度研究语言发展的历史,观察一种语言的各个结构要素在不同发展阶段的历史演变,是从纵向的方面研究语言的历史. ,探讨人类语言的共同规律,是在具体语言学基础上建立起来的,下面又分普通语音学,普通语法学,普通词汇学等分支学科. 二,填空题(分,每空分) .中国印度古希腊罗马 .文字学音韵学训诂学 .语音词汇和语义语法 .编码发送传递接收 .历时共时历史描写 .历史比较 .《语言论》 .索绪尔 三,问答题(分,每小题分) ①研究对象不同:古代的语言学主要以书面语为主要研究材料,不重视口头语言的研究,而今天的语言学则十分重视口语研究,如制定语言规范,确立共同语的各方面标准等,都要依据口语的研究成果; ②研究目的不同:古代语言学研究语言,主要是给政治,哲学,宗教,历史,文学方面的经典著作作注解,比如我国古代的语文学主要就是围绕阅读先秦经典著作的需要来研究文言的,而现代语言学的研究目的主要是分析语言的结构,以此探讨语言发展的共同规律. 正因为有这些差别,所以古代的语言学还不是独立的学科,处于附庸地位,而现代语言学已经发展成为一门独立的学科,随着现代科学的发展又产生了许多边沿性学科. 人类语言交际的过程,实际上就是信息的传递与接收问题,可分为编码,发送,传递,接收,解码五个阶段.编码就是发话人利用词语组织语句;发送就是把思维成果变成话语,通过发音器官表达出来;传递就是通过空气振动形成声波,把话语传达给受话人;接收是受话人利用听觉器官感知对方所说的话;解码则经过大脑的思维把声波还原成语言,理解对方话语的含义,从而完成信息传递接收.如果受话人收到语言信息有所反馈,那么上述五个阶段则又重复一遍,只是发话人与受话人调换了. (举例说明略,可结合分析任举一个句子作说明.) 语言是伴随着人类一起出现的,是人类社会生活必不可少的,所以人类很早就注意到了语言的重要性,很早就注意研究语言,所以语言学是古老的,但语言学直到世纪下半叶,产生了历史比较语言学,后来又建立了语言学的各个部门,语言研究才发展成为一门独立的学科,同其它学科相比,语言学的确是十分年轻的.语言是社会现象,与社会的政治,经济,文化,历史等密切相关,而语言的发生又与物理,生理,心理等学科密切相关,而现代社会语言与语言的信息处理(如机器翻译,语码转换等)又涉及到数学,计算机科学,所以语言学既与社会科学有密切的联系,又与自然科学有密切的联系.正因为如此,随着语言学与别的学科的交融,又产生了许多新的语言学分支学科,如社会语言学,心理语言学,统计语言学,话语语言学,数理语言学,宇宙语言学等等,这些也体现了语言学是一门年轻的学科. 语言学的作用主要表现在以下几个方面:①学习语言文字是掌握科学技术,提高文化水平的基础,而要学好用好语言,就必须利用语言学的研究成果;②制定语言文字的有关政策,制定语言规范,都要在对语言进行充分研究的基础上进行,而语言学的研究成果正好可以作指导;③新兴技术的出现扩大了语言学的应用范围.至于个人,同样可以利用语言学的成果,比如学习一种语言或方言,最好的办法是找到所学语言同自己母语的各方面的对应规律,这样可以收到事半功倍的效果,这就需要利用语言学的研究成果. (结合实际部分可以根据自己的学习,工作或生活经历举例) 语言学首先可以分为理论语言学和应用语言学,一般所说的语言学,主要是指理论语言学.根据研究对象的不同,理论语言学又分普通语言学和专语语言学(具体语言学).普通语言学以人类所有的语言为研究对象,探讨人类语言的共同规律,是在具体语言学基础上建立起来的,下面又分普通语音学,普通语法学,普通词汇学等分支学科.专语语言学以个别的,具体的语言为研究对象.探讨研究某一种语言的规律.从是静态研究还是研究语言的历史看,又分历时语言学和共时语言学:历时语言学研究具体语言的发展历史,是纵向研究,比如汉语史研究,共时语言学研究具体语言在某一时代的状态(相对静止的状态),规律,对之进行客观的描述,是横向研究.如描写语言学,又分描写语音学,描写语汇学,描写语法学等分支学科,现代汉语就是共时语言学. .在历史语言学产生以前,语言学

Chapter 3 Morphology 1. What is word? ?Definition: A unit of expression that has universal intuitive recognition by native speakers, whether it is expressed in spoken or written form. ? A vague definition.Three senses are involved in defining “word”, none of which is satisfactory to cope with all the situations. 1.1 Identification of words ?Stability:stable linguistic units. chairman, but not *manchair ?Relative uninterruptibility:though we recognize three components in the word disappointment, we cannot pause and add another component in between, as in *disinterestappointment. But we can add another word between words: Paul, (John) and Mary ... ? A minimum free form: the smallest unit that can constitute a complete utterance by itself. Sentence---the maximum free form Word---the minimum free form, the smallest unit that can constitute, by itself, a complete utterance ?Eg --Is Jane coming tonight? --Possibly. Hi. Wonderful. ?词的特征 词是由词素构成,比词素高一级的句法单位。词具有以下特征: 一词具有固定的语音形式。 二词具有一定的意义。词可以分属实义语类和功能语类。实义语类主要表示词汇意义,包括名词,动词,形容词,副词和介词。功能语类主要表示语法意义,起连接或附着作用,包括限定词,助动词,代词,标句词和连词。 三词是能够独立运用的最小的语言单位。 2 Classification of words 2.1 Variable and invariable words ?V ariable words:One could find ordered and regular series of grammatically different word forms; on the other hand, part of the word remains constant follow, follows, following, followed; mat, mats ?Invariable words: those words such as since, when, seldom, through, hello. They do not have inflective endings. 2.2 Grammatical words and lexical words Grammatical words:express grammatical meanings, such as conjunctions, prepositions,

导言 *中国、印度、希腊、罗马具有悠久的历史文化传统,是语言学的三大发源地之。 *形成了统称“小学”的文字、音韵、训诂的我国传统语文学。 *语言本身的构造很复杂,对它的研究大致可以分为语言、词汇和语义、语法三个部分。 *运用语言交际的过程是瞬间的事情,但却包含着一系列复杂的问题。如果借用信息论的术语来说,这一过程大体上可以分为“编码—发送—传递—接收—解码”五个阶段。 第一章 *语言研究的任务就是要把说话中反复使用的材料和规则找出来,把那些隐藏在无数话语中的坚守不见尾的语言找出来,使它的整体和每一片鳞甲都清清楚楚地展现在人们的面前。这当然是复杂细致的任务。 *除了语言之外,人们还可以使用其他的交际工具:文字,旗语,红绿灯,电报代码,数字符号,化学公式等。人们在使用语言进行交际的时候,不但要动嘴,而且要面部的表情、手的动作、乃至整个躯体的姿态等非语言的东西也都会参加进来。(非语言:手、眼神) *思维能力是全人类共同的,语言的各组民族不同的。 *为什么语言是人类最重要的交际工具? 1、语言是最灵活的,最方便的,信息量最大的,所以是最重要的。语言是组成社会不可少的因素,人与人之间的联系要靠语言来维持。 2、语言是为满足人类交际的组要而产生的,其他动物是没有的。 3、其他的交际工具是建立在一定的语言基础上的语言或语言成分的代用品,而且都有特殊的服务领域。 第二章 *符号:是一个社会全体成员共同约定用来表示某种意义的记号标记。符号应该具备的条件:约定俗成、重复使用。语言符号的特点是:任意性和线条性。 *语言是一种分层装置,这种装置靠组合和替换来运转。语言必须是一种经济有效而又富于弹性和灵活性的装置。这装置的重要特点就是分层。 *语言的底层是一套音位,一种语言的音位的数目虽然只有几十个却能构成数目众多的组合,这些组合为语言符号准备了形式的部分。语言的上层是音义结合的符号和符号的序列,这一层又氛围若干级。第一级是语素,意义在这里被装进形式的口袋,成了音义结合的最小的符号。第二级是由语素构成的词,第三级是由词构成的句子。词和句子都是符号的序列。 *组合关系和聚合关系是语言两种最根本关系。 第三章 *音素:是从音节中划分出来的最小的语音单位。(从音质角度划分出来) *音标:记录音素的标写符号。国际音标:是国际语言协会于1888年制定的并开始使用的一套记录音素的标写符号。 *语音的发音---传递---感知三个环节,分别对应于语音的生理---物理---心理三个方面的属性,由发音学---音响学---听觉语音学三门学科加以研究,标志着人们研究语言的的进展过程。三个环节,三个方面,三门学科的研究都是自然科学和语言学的交界领域,都要利用大量的实验手段。生理、物理、心理的研究可以说是语音的自然属性的研究。 *元音和辅音的区别是什么? 1、气流是否受阻,发元音气流不受阻,辅音受阻。 2、发音器官紧张状况。发元音时各器官的各部分都保持均衡紧张,发辅音时只有形成阻碍的那一部分特别紧张。 3、气流强弱不同,发元音气流弱,发辅音气流强。 *音位:是具体语言中有区别的语音形式的作用的最小语音单位。音位的分析对拼音文字的

CH 5 Morphology 的上課筆記 1. What is morphology? 2. How to use it? Who is it for? 3. When to use it? 4. Are there rules in it? 5. Is there an infix in English? 6. The use/ significance of the morphology. Morphology (構詞學) is (1) the study of morphemes and their different forms (allomorphs), and the way they combine in word formation, i.e., the English word unfriendly is formed from friend , the adjective-forming suffix -ly and the negative prefix un-. (2) a morphemic system(詞素系統). Morphology helps people recognize possible words. 有沒有新字的出現? 例子1: Bug → a possible word Bog → a possible word Sog → not a possible word 例子2: 木神 → Morphology ( it depends on people)

(1) 昨晚我的ㄅㄧㄤˋ痛得睡不著。 →從這句話大概知道句子要表達意思:某人遭受疼痛之苦, 但不是能清楚知道每個字(individual words)的意思。 在訓練聽力時,是訓練學生get the main concept (idea) in the context/ dialogue. (2) 我的手臂上長了一個ㄅㄧㄤˋ,很癢。 →ㄅㄧㄤˋ可能是瘤或青春痘。 (3) 我的腳上長了一個ㄅㄧㄤˋ,不舒服。 →ㄅㄧㄤˋ可能是皮膚病。 (1)→(2)→(3):從不同的context,慢慢會懂“ㄅㄧㄤˋ”的意義,但還是有點模糊。 直到你看到實物的那一天,才能真正了解其意義。 因為文字本身就是抽象的,所以如果用文字去表達一個抽象的概念,會很難懂;但若是用具體的實物來講解,會比較容易明白。 教單字→可以把圖片運用在單字教學上。 Morphology可以幫助學習新單字。 例子4: A: Have you seen ―wuggles‖ before? B: What are ―wuggles‖ ? A: They are four-legged animals. B: What do they look like? Dogs, cats, rabbits, or horses? A: No, they look like spiders. B: They are six-legged insects. 因為―wuggles‖(a possible word)符合造字原則,所以B會問What are ―wuggles‖ ?
