班班幼儿园第二章英文Chapter 2: English at Banban KindergartenIntroduction:English language learning is an important aspect of education at Banban Kindergarten. In Chapter 2, we will explore the various methods and strategies used to teach English to our young learners. The curriculum is designed to provide a comprehensive and engaging English learning experience, focusing on four key areas: listening, speaking, reading, and writing. Through a combination of interactive activities, games, and songs, children develop their English language skills in a fun and stimulating environment.Listening:At Banban Kindergarten, listening skills are developed through various activities that encourage active listening and comprehension. Teachers use audio materials, such as English stories or songs, to expose children to different accents, intonations, and vocabulary. This helps them to develop their listening skills and comprehension abilities gradually.Additionally, teachers engage students in classroom discussions, group activities, and storytelling sessions, which further enhance their listening skills. By actively participating in these activities, children become more confident in their ability to understand spoken English.Speaking:To foster speaking skills, teachers at Banban Kindergarten use a communicative approach. From the moment children step into the classroom, English is the primary language of instruction. Teachers use simple, clear language and encourage children to express themselves in English. Activities such as role-plays, pair work, and games are incorporated into the curriculum to encourage children to speak confidently and fluently. Through frequent practice and positive reinforcement, children gradually gain confidence in using English to communicate with their teachers and peers.Reading:Reading is an essential part of language development, and at Banban Kindergarten, we aim to cultivate a love for reading in our students. The curriculum includes a wide range of storybooks, picture books, and leveled readers that are suitablefor young learners. Teachers create a welcoming reading corner within the classroom, stocked with books that cater to different reading abilities and interests. Through shared reading sessions, guided reading activities, and independent reading time, children develop reading skills such as phonics, word recognition, and comprehension. The goal is to instill a lifelong love for reading and provide a solid foundation in literacy.Writing:Writing skills are introduced gradually at Banban Kindergarten, beginning with the basics of letter formation and phonics. Teachers provide guided writing activities and encourage children to write simple sentences and short paragraphs. Through interactive writing exercises, children learn to express their ideas and thoughts in English, gradually improving their writing abilities. Teachers provide constructive feedback and assist students in improving their grammar, vocabulary, and sentence structure. The focus is on creating a positive and supportive environment that encourages children to practice and develop their writing skills.Assessment:At Banban Kindergarten, assessment is an integral part of thelearning process. Teachers use a variety of assessment methods to track each child's progress and identify areas for improvement. These methods include observation, informal assessments, and periodic tests. Teachers provide feedback to both students and parents regularly, highlighting areas of strength and areas that need improvement. This feedback helps parents to stay informed about their child's progress and actively engage in their English language learning journey.Conclusion:English language learning at Banban Kindergarten is designedto be an immersive and enjoyable experience for young learners. By focusing on listening, speaking, reading, and writing skills, children develop a solid foundation in English language proficiency. Through a combination of interactive activities, engaging materials, and skilled teachers, students gain confidence in using English to communicate effectively. The goal is to equip children with the necessary language skills to succeed in their future academic endeavors and beyond.。

Given that the scale of the downturn was so epochal, it should not be surprising that the nature of the recovery would likewise be the stuff of history. And it has been.

walden chapter2译文
walden chapter2译文瓦尔登湖.第二章我生活的地方;我为何生活亨利大卫.梭罗八月里,在轻柔的斜凤细雨暂停的时候,这小小的湖做我的邻居,最为珍贵,那时水和空气都完全平静了,天空中却密布着乌云,下午才过了一半却已具备了一切黄昏的肃穆,而画眉在四周唱歌,隔岸相闻。
这样的湖,再没有比这时候更平静的了;湖上的明净的空气自然很稀薄,而且给乌云映得很黯淡了,湖水却充满了光明和倒影,成为一个下界的天空,更加值得珍视。
从最近被伐木的附近一个封顶上向南看,穿过小山间的巨大凹处,看得见葛湖的一副愉快的图景,那凹处正好形成湖岸那儿两座小山坡乡倾斜而下,使人感觉到似有一条溪涧,从山林谷中留下,但是却没有溪涧。
我是这样的从近处的绿色山峰之间和之上远望一些蔚蓝的地平线上的远山或更高的山峰。
真的垫起足尖来,我可以望见西北角上更远更蓝的山脉,这种蓝颜色是天空的染料制造厂中最真实的出品,我还可以望见村镇的一角,但是要换一个方向看的话,虽然我站得如此高,却给郁茂的树木围住,什么也看不透,看不到了。
在邻近,有一些流水真好,水有浮力地就浮在上面了。
便是最小的井也有这一点值得推荐,当你窥望井底的时候,你发现大地并不是连绵的大陆;而是隔绝的孤岛。
这是很重要的,正如井水之能冷藏牛油。
当我的目光从这一个山顶越过湖向萨德伯里草原望过去的时候,在发大水的季节里,我觉得草原升高了,大约是蒸腾的山谷中显示出海市蜃楼的效果,它好像沉在水盆底下的一个天然铸成的铜币,湖之外的大地都好像薄薄的表皮,成了孤岛,给小小一片横亘的水波浮载着,我才被提醒,我居住的地方只不过是干燥的土地。
虽然从我的门口望出去,风景范围更狭隘,我却一点不觉得它拥挤,更无被囚禁的感觉。
尽够我的想象力在那里游牧的了。
矮橡树丛生的高原升起在对岸,一直向西去的大平原和鞑靼式的草原伸展开去,给所有的流浪人家一个广阔的天地。
当达摩达拉的牛羊群需要更大的新牧场时,他说过,"再没有比自由地欣赏广阔的地平线的人更快活的人了。

Discrete-Time Signals: Time-Domain Representation
• A right-sided sequence x[n] has zerovalued samples for n < N1
A right-sided sequence
•If N1 0, a right-sided sequence is called a causal sequence
In some applications, a discrete-time sequence {x[n]} may be generated by periodically sampling a continuous-time signal xa(t) at uniform intervals of time
Discrete-Time Signals: Time-Domain Representation
• Discrete-time signal may also be written as a sequence of numbers inside braces: {x[n]}={…,-0.2,2.2,1.1,0.2,-3.7,2.9,…} • The arrow is placed under the sample at time index n = 0 • In the above, x[-1]= -0.2, x[0]=2.2, x[1]=1.1, etc.
Discrete-Time Signals: Time-Domain Representation
• Graphical representation of a discrete-time signal with realvalued samples is as shown below:
新编简明英语语言学教程chapter2笔记
Chapter 2 Phonology2.1 The phonic medium of language (Lead in)Language is primarily vocal. The primary medium of human language is sound. Linguists are not interested in all sounds, but in speech sounds----sounds that convey meaning in human communication.Sounds which are meaningful in human communication constitute the phonic medium of language.Language is a “system of vocal symbols”. Speech sounds had existed long before writing was invented, and even today, in some parts of the world, there are still languages that have no writing system. Therefore, the study of speech sounds is a major part of linguistics.2.2 Phonetics2.2.1 What is phonetics?----A branch of linguistics which studies the characteristics of speech sounds and provides methods for their description, classification and transcription, e.g. [p] bilabial, stop.Phonetics looks at speech sounds from three distinct but related points of view:(Speech production-----------------speech transmission---------------speech perception)⏹Articulatory phonetics(发音语音学)----from the speakers‟point of view, “how speakers produce speechsounds”⏹Auditory phonetics(听觉语音学)----from the hearers‟ point of view, “how sounds are perceived”⏹Acoustic phonetics(声学语音学)----from the physical way or means by which sounds are transmitted from oneto another.2.2.2 Organs of speechSpeech organs, also known as V ocal organs, are those parts of the human body involved in the production of speech. The diagram of speech organs:1. Lips 7. Tip of tongue2. Teeth 8. Blade of tongue3. Teeth ridge (alveolar) 9. Back of tongue4. Hard palate 10. V ocal cords5. Soft palate (velum) 11.Pharyngeal cavity6. Uvula 12. Nasal cavityThe important cavities:☆The pharyngeal cavity 咽腔---- the throatLarynx: at the top of the trachea, the front of which is the Adam‟s apple. This is the first place where sound modification might occur. The larynx contains the Vocal folds, also known as Vocal cords or Vocal bands. The vocal folds are a pair of structure that lies horizontally with their front ends joined together at the back of the Adam‟s apple. Their rear ends, however, remain separated and can move to various positions. The vocal folds are either (a) apart, (b) close together, (c) totally closed.Vibration of the vocal cords results in a quality of speech sounds called voicing, which is a feature of all vowels and some consonants in English.Voiceless: when the vocal cords are spread apart, the air from the lungs passes between them unimpeded.V oiced (V oicing): when the vocal cords are drawn together, the air from the lungs repeated pushes them apart as it passes through, creating a vibration effect.☆The oral cavity 口腔---- the mouthThe oral cavity provides the greatest source of modification of the air stream. ([k]/[g], [t]/[d], [θ]/[δ], [f]/[v], [p]/[b])☆The nasal cavity 鼻腔---- the noseThe nasal cavity is connected with the oral cavity. The soft part of the roof of the mouth, the velum, can be drawn back to close the passage so that all air exiting from the lungs can only go through the mouth. The sounds produced in this condition are not nasalized. If the passage is left open to allow air to exit through the nose, the sounds produced are nasalized sounds.2.2.3 Orthographic representation of speech sounds--- broad and narrow transcriptions(语音的正字法表征:宽式/窄式标音)---- A standardized and internationally accepted system of phonetic transcription is the International Phonetic Alphabet (IPA). The basic principle of the IPA is using one letter to represent one speech sound.Broad transcription: the transcription with letter-symbols only(代表字母的符号)e.g. clear [l]Narrow transcription: the transcription with letter-symbols together with the diacritics. e.g. dark [ l ], aspirated [ p ] (Diacritics are additional symbols or marks used together with the consonant and vowel symbols to indicate nuances of change in their pronunciation.)E.g. : [l]→[li:f]--→ a clear [l] (no diacritic); [l]→[bild]--→a dark [l] (~)[p]→[pit]--→an aspirated [p h](h表示送气)[p]→[spit]--→an unaspirated [p] (no diacritic)2.2.4 Classification of English speech sounds---- English speech sounds are generally classified into two large categories:⏹V owels⏹ConsonantsNote: The essential difference between these two classes is that in the production of the former the air stream meets with no obstruction of any kind in the throat, the nose or the mouth, while in that of the latter it is somehow obstructed.2.2.4.1 Classification of English consonantsEnglish consonants can be classified either in terms of manner of articulation or in terms of place of articulation.In terms of manner of articulation根据发音方法分(the manner in which obstruction is created)① Stops闭塞音: the obstruction is total or complete, and then going abruptly[p]/[b], [t]/[d], [k]/[g]② Fricatives摩擦音: the obstruction is partial, and the air is forced through a narrow passage in the month[f]/[v], [s]/[z], [∫]/[з], [θ]/[δ], [h] (approximant)③ Affricates塞擦音: the obstruction, complete at first, is released slowly as in fricatives [t∫]/[dз]④ Liquids流音: the airflow is obstructed but is allowed to escape through the passage between part or parts of the tongue and the roof of the mouth[l]→a lateral sound; [r]→ retroflex⑤ Glides滑音: [w], [j] (semi-vowels)Liquid + glides + [h]→ approximants⑥ Nasals鼻音: the nasal passage is opened by lowering the soft palate to let air pass through it[m], [n], [η]By place of articulation根据发音部位分(the place where obstruction is created)①bilabial双唇音: upper and lower lips are brought together to create obstructions [p]/[b], [w]→(velar)②labiodentals唇齿音: the lower lip and the upper teeth [f]/[v]③dental齿音:the tip of the tongue and the upper front teeth [θ]/[δ]④alveolar齿龈音: the front part of the tongue on the alveolar ridge [t]/[d], [s]/[z], [n], [l], [r]⑤palatal腭音: tongue in the middle of the p alate [θ]/[δ], [t∫]/[dз], [j]⑥velars软腭音:the back of the tongue against the velum [k], [g], [η]⑦glottal喉音: the glottal is the space between the vocal cords in the larynx [h]Conclusion: Factors to describe a consonant(1) State of vocal cords (VL/VD)(2) Manner of articulation (MA)(3) Place of articulation (PA)2.2.4.2 Classification of English vowelsV owel sounds are classified according to: the position of the tongue in the mouth, the openness of the mouth, the shape of the lips, and the length of the vowels.Highest Part of the tongue (front, central, back)Front vowels are the ones in the production of which the front part of the tongue is raised the highest such as [i:] [i] [e] [æ] [a].When the central part of the tongue maintains its highest position, the vowels thus produced are central vowels such as [3:] [Ə] and [ ] .If the back of the tongue is held the highest, the vowels thus produced are back vowels such as [u:][u] Openness of mouthRounded or unrounded lipsrounded vowels: All the back vowels in English are rounded except [ɑ:].unrounded vowels: All the front vowels and central vowels in English are unrounded.Length of the vowellong vowels: They are usually marked with a colon such as [i:] and [ɑ:]short vowels: other vowels in English are short vowels such as [e], [ə] and [æ].monophthongs: individual vowelsdiphthongs: produced by moving from one vowel position to another through intervening positions. (集中/合口)2.3 Phonology2.3.1 Phonology and phoneticsWhat does English phonetics deal with?English phonetics is concerned with all speech sounds that occur in the English language. It studies how these sounds are produced and how they are described and classified.What does English phonology deal with?English phonology investigates the sound system of English. Different from English phonetics, English phonology is not interested in the actual production of English sounds, but in the abstract aspects:A. the function of sounds--- whether a sound can differentiate the meanings of wordsB. their patterns of combination--- how sounds are combined to form a permissible sound sequence⏹Both are concerned with the same aspect of language----the speech sounds. But they differ in their approachand focus.⏹Phonetics is of general nature; it is interested in all the speech sounds used in all human languages; it aims toanswer questions like: how they are produced, how they differ from each other, what phonetic features they have, how they can be classified, etc.⏹Phonology aims to discover how speech sounds in a language form patterns and how these sounds are used toconvey meaning in linguistic communication.(Speaker‟s mind--- Mouth--- Ear--- Listener‟s mind)2.3.2 Phone, phoneme, and allophonePhoneme: minimal distinctive unit in sound system of a language; a phoneme is a phonological unit; it is a unit of distinctive value, it is an abstract unit; not a particular sound, but it is represented by a certain phone in certain phonetic context, e.g. the phoneme /p/ can be represented differently in [pIt], [tIp] and [spIt].Phone: a phone is a phonetic unit or segment; the realization of phoneme in general. The speech sounds we hear and produce during linguistic communication are all phones. Phones do not necessarily distinguish meaning, some do, some don‟t. For example, in the words feel[fi:ł], leaf[li:f], tar[t h a:], star[sta:],there are altogether 7 phones: [f],[i:],[ł], [l], [t h]. [t], [a:], but [ł] and[l] do not distinguish meaning, [t h] and [t] do not distinguish meaning as well.Allomophone: the different phones which can represent a phoneme in different phonetic environments are called the allophones of that phoneme; realizations of a particular phoneme.2.3.3 Phonemic contrast, complementary distribution, and minimal pairPhonemic contrast: when two phonemes can occur in the same environments in two words and they distinguish meaning, they‟re in phonemic contrast.E.g. pin & bin → /p/ vs. /b/ rope & robe → /p/ vs. /b/Complementary distribution:two or more than two allophones of the same phonemes are said to be in complementary distribution because they can not appear at the same time, or occur in different environment, besides they do not distinguish meaning.E.g. dark [l] & clear [l], aspirated [p] & unaspirated [p]Minimal pair: when two different forms are identical in every way except for one sound segment which occurs in the same place in the strings, the two sounds are said to form a minimal pair.E. g. mail vs. nail beat, bit, bet, bat, boot, but, bait, bite, boat2.3.4 Some rules in phonology2.3.4.1 Sequential rulesSequential rules ---- the rules that govern the combination of sounds in a particular language, e.g. in English, “k b i I” might possibly form blik, klib, bilk, kilb.⏹If a word begins with a [l] or a [r], then the next sound must be a vowel.⏹If three consonants should cluster together at the beginning of a word, the combination should obey thefollowing three rules, e.g. spring, strict, square, splendid, screama) the first phoneme must be /s/,b) the second phoneme must be /p/ or /t/ or /k/,c) the third phoneme must be /l/ or /r/ or /w/.⏹The affricates [t∫],[dз] and the sibilants [s],[z],[θ],[δ]are not to be followed by anothersibilants.2.3.4.2 Assimilation ruleAssimilation: articulatory adaptation of one sound to a nearby sound with regard to one or more features.Nasalization: /m/, /n/, /ŋ/[-nasal]→ [+nasal]/_______ [+nasal]Dentalization: /ð/, /θ/[-dental]→[+dental]/______[+dental]V elarizatio n: /k/, /g/, / ŋ/: Word-final /n/ becomes velar before velar plosives/k, g/: ten cups; ten girls[-velar]→ [+ velar]/______[+velar]2.3.4.3 Deletion ruleDeletion rule---- it tells us when a sound is to be deleted although it is orthographically represented, e.g. design, paradigm, there is no [g] sound; but the [g] sound is pronounced in their corresponding forms signature, designation, paradigmatic.E.g. delete a [g] when it occurs before a final nasal consonant 省略词末鼻辅音前的[g]音2.3.5 Suprasegmental features--- stress, tone, intonationsegmental features(切分特征)--- the distinctive features which can only have an effect on one sound segment are called segmental features.Suprasegmental features----the phonemic features that involve more than single sound segments (larger than phoneme)2.3.5.1 StressWord stress⏹The location of stress in English distinguishes meaning, e.g. a shift in stress in English may change the part ofspeech of a word:verb: im‟port; in‟crease; re‟bel; re‟cord …noun: …import; …increase; …rebel; …record …⏹Similar alteration of stress also occurs between a compound noun and a phrase consisting of the sameelements:compound: …blackbird; …greenhouse; …hotdog…noun phrase: black …bird; green …house; hot …dog…⏹The meaning-distinctive role played by word stress is also manifested in the combinations of -ing forms andnouns:modifier: …dining-room; …reading room; …sleeping bag…doer: sleeping …baby; swimming …fish; flying …plane…Sentence stressSentence stress----the relative force given to the components of a sentence. Generally, nouns, main verbs, adjectives, adverbs, numerals and demonstrative pronouns are stressed. Other categories like articles, person pronouns, auxiliary verbs prepositions and conjunctions are usually not stressed.Note: for pragmatic reason, this rule is not always right, e.g. we may stress any part in the following sentences.He is driving my car.My mother bought me a new skirt yesterday.2.3.5.2 T oneTones are pitch variations, which are caused by the differing rates of vibration of the vocal cords.⏹English is not a tone language, but Chinese is.ma 妈(level)ma 麻(the second rise)ma 马(the third rise)ma 骂(the fourth fall)2.3.5.3 IntonationWhen pitch, stress and length variations are tied to the sentence rather than to the word, they are collectively known as intonation.English has three types of intonation that are most frequently used (first three types):falling tone (matter of fact statement)rising tone (doubts or question)the fall-rise tone (implied message)the rise-fall toneHe is not ↘ there. What did you put in my ↗ drink, ↘ Jane?He is not ↗ there? What did you put in my ↘ drink, ↗ Jane?For instance,“That’s not the book he wants.”Ss exercise: Explain the meaning of the following words or phrases or sentences when marked with different stress or with different intonation.Assignments1. Ss complete the review questions during the classes.2. Ask students to do the exercises 1-10 on Page 30.。

1.2Chapter2故事回顾:每天精打细算的Della为了给丈夫Jim买一件圣诞礼物,不惜剪掉了一头秀发,并用换来的钱为丈夫配了一条金表链。
而下班回家后的Jim看到短发的Della又将会说些什么?The shop took twenty-one dollars from her for it, and she hurried home7with the eighty-seven cents.商店收了她21块钱,她带着剩下的8毛7分钱匆匆地回家了。
When she arrived there,she looked at her very short hair in the glass.‘What can I do with it?’she thought.For the next half an hour she was very busy.回家以后,她从镜子里打量着自己的短头发。
“我该怎么打理一下呢?”她想。
接下来的半个小时里,她忙成了一团。
Then she looked again in the glass.Her hair was now in very small curls8all over her head.‘Oh,dear.I look like a schoolgirl!’she said to herself.‘What’s Jim going to say when he sees me?’然后她又照了照镜子。
现在她满头都是小卷卷儿。
“哦,天哪!我看上去像个小女生!”她自言自语道,“Jim看到我会怎么说呢?”At seven o’clock the dinner was nearly ready and Della was waiting.‘Oh,I hope he thinks that I’m still beautiful!’she thought.7点钟,晚餐就快做好了,Della等着Jim回来。
英语语言学Chapter2
英语语⾔学Chapter2Chapter T woⅡ. Fill in each of the following blanks with one word which begins with the letter given:1. A refers to a strong puff of airstream in the production of speech sounds.2. A phonetics describes the way our speech organs work to produce the speech sounds and how they differ.3. The four sounds /p/, /b/, /m/ and /w/ have one feature in common, i.e., they are all bsounds.4. Of all the speech organs, the t is the most flexible, and is responsible for varieties of articulation than any other.5. English consonants can be classified in terms of manner of articulation or in terms of pof articulation.6. When the obstruction created by the speech organs is total or complete, the speech sound produced with the obstruction audibly released and the air passing out again is called ass.7. S features are the phonemic features that occur above the level of the segments. They include stress, tone, intonation, etc.8. The rules that govern the combination of sounds in a particular language are called srules.9. The transcription of speech sounds with letter-symbols only is called broad transcription while the transcription with letter-symbols together with the diacritics is called ntranscription.10. When pitch, stress and sound length are tied to the sentence rather than the word in isolation, they are collectively known as i.11. P is a discipline which studies the system of sounds of a particular language and how sounds are combined into meaningful units to effect linguistic communication.12. The articulatory apparatus of a human being are contained in three important cavities: the pharyngeal cavity, the o cavity and the nasal cavity.13. T one are pitch variations, which are caused by the differing rates of vibration of the vocal cords and which can distinguish meaning just like phonemes.14. Depending on the context in which stress is considered, there are two kinds of stress: word stress and s stress.perception.16. The articulatory apparatus of a human being are embedded in three important cavities. These three cavities are p o and n cavitythe production of them.18. Vis a feature of all vowels and some consonants. When the vocal cords do cause vibration, the sounds produced are ; otherwise they are named sounds19. Two ways to transcribe speech sounds are available, broad transcription and narrow transcription. The major difference between them is with or without .20. When the obstruction is partial and the air is forced through an arrow passage in the mouth soas to cause definite local friction at the point, the speech sound thus produced is a .21. The basic unit of phonology is a phoneme. It is an abstract collection of .22. When phonemic contrast is mentioned we realize that the two sounds belong tophoneme(s), when complementary distribution is discussed, the allophones come from phoneme(s); and finally when free variation is talked about, we understand that the sounds are derived from phoneme(s).23. In English, complementary distribution of allophones is required to meet two conditions, one condition is that they never occur in the ; the other is that they shouldshare .24. In English, the study of phonology hasso far mainly found three phonological rules. They areand rule.III. There are four choices following each statement.

2 找什么? 范围确定之后,可能成为对象的是: 1)结构:最有可能被认定为对象的实体,分类结构 和组装结构。 2)其他系统:指要进行交互的外部系统。 3)设备:需要进行交互的设备。 4)事件:由系统及时观察和记录的事件。 5)扮演的角色:各种人员在系统中扮演的角色。 6)位置:系统安装和运行的物理位置。 7)组织和单位:系统涉及的人员所属单位。
2.3.4 Relationship Among the Models
Each model describes one aspect of the system but contains references to the other models.
Chapter 3 Class Modeling
3.1.1 Objects often appear as proper nouns or specific references in problem descriptions and discussions with users.
(P21, par.3)
简单的认定方法:基于词法分析的方法。从目标系 统的描述开始,找出其中的名词作为候选的对象。 复杂系统对象的认定:需要回答5个问题。
(P22, par.3)
大多数对象从其属性值的差异以及与其他对象的特 定关系中可以彼此区分。类的选取依赖于某项应用 的性质和范围,这是一个判断的问题。
3.1.3 Class Diagrams & Object Diagrams
Class diagrams provide a graphic notation for modeling classes and their relationships, thereby describing possible objects. Class diagrams are useful both for abstract modeling and for designing actual programs.
3 对候选对象考察什么? 对于候选对象,能否认定它是一个对象要考察: 1)需要记忆:即系统是否有必要记忆对象的某些或 全部成分? 2)需要服务:即系统是否有必要对该对象的行为提 供服务? 3)多于一个属性:只有一个属性的对象通常应看成 其他对象的属性? 4)共有属性:即对于一种对象所有实例,能否认定 一组为这些实例所共有的属性? 5)共有服务:即对于一种对象所有实例,能否认定 一组这些实例都要进行的加工?
Chapter 2 Modeling
Modeling as a Design Technique
A model is an abstraction of something for the purpose of understanding it before building it. (P15, par.1, first sentence) To build complex systems, the developer must abstract different views of the system, build models using precise notations, verify that the models satisfy the requirements of the system and gradually add detail to transform the models into an implementation. (P15, par.1, last sentence)
2.3.1 Class Model The class model describes the structure of objects in a system – their identity, their relationship to other objects, their attributes, and their operations. The goal in constructing a class model is to capture those concepts from the real world that are important to an application. Class Diagram
(P22, par.2)
类描述了拥有相同特性(属性)、行为(操作)、关系 以及语义的一组对象。
Mfrom differences in their attribute values and specific relationships to other objects. The choice of classes depends on the nature and scope of an application and is a matter of judgment.
对象图显示了单独的对象及其关系。一个类图相当 于无限多个对象图的集合。

2.2 Abstraction
Abstraction must always be for some purpose, because the purpose determines what is, and is not, important. Many different abstraction of the same thing are possible, depending on the purpose for which they are made.
5 怎样为认定的对象命名? 认定的对象需要命名,这时应当: 1)用单数名词或形容词加名词来命名对象的名字 2)命名所使用的词汇应当来自符合系统主题、标准 的词汇集 3)使用可读的名字,要基于内容,基于内在的本质, 具有确切意义
3.1.2 A class describes a group of objects with the same properties (attributes), behavior (operations), kinds of relationships, and semantics.
2.3.2 State Model The state model describes those aspects of objects concerned with time and the sequencing of operations – events that mark changes, states that define the context for events, and the organization of events and states. State Diagram
(P21, par.1, first sentence)
The class model is the most important of 类模型描述系统内部对象的特征、对象之间的相互 the three models. 关系以及对象所属类具有的属性、操作和方法,是
描述系统的静态特征的。
3.1 Object and Class Concepts
2.3 The Three Models
We find it useful to model a system from three related but different viewpoints, each capturing important aspects of the system, but all required for a complete description.
The three kinds models separate a system into distinct views. The different models are not completely independent – a system is more than a collection of independent parts – but each model can be examined and understood by itself to a large extent. The different models have limited and explicit interconnections. A good design isolates the different aspects of a system and limits the coupling between them.
4 提出什么质疑? 对于初步认定的对象,从以下几个方面提出质疑: 1)记忆和服务的必要性:若系统没有必要始终保留 某种事物的信息或者提供关于它的服务,那么这 种事物就不要认定为对象。 2)单个实例:若某种有属性的对象只有一个实例, 且有其他的两种或多种对象有相同的属性和行为, 这是应当考虑将它们合并。 3)派生结果:注意那些可以通过计算机得出值的属 性。
2.3.3 Interaction Model The interaction model describes interaction between objects – how individual objects collaborate to achieve the behavior of the system as a whole. Use Cases, Sequence Diagram, Activity Diagram
