Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic / logic unit (ALU).The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical (comparison) functions — that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically ―less than‖, ―greater than‖, and ―equal to‖, can be combined into several common expressions, such as ―greater than or equal to‖. The objective of most instructions that use comparisons is to determine which instruction should be executed next.Tell whether the following statements are true(T) or false(F) according to the passage A.（根据上文的内容判断下列句子的正误）1.With the development of computer, the physical size of the CPU has often become bigger and bigger.( F)2.The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU andinput /output devices are controlled by the control unit of the CPU.( T)3.The CPU comprises the control unit and memory.

1Arbitrariness: Human language is arbitrary. This refers to the f act that there is no logical or intrinsic connection between a particular sound and the meaning it is associated with. For example, f or the same animal dog, in English we call it /d0g/, inCh inese as “gou”, but “yilu” in Japanese.2Duality:To human language, the way meaningless elements of language at one level (sounds and letters) combine to f orm meaningf ul units (words) at anotherlevel.3A descriptive linguisticsattempts to tell what is in the language, it attempts to describe the regular structures of the language as they are used, not according to some view of how they should be used. While the prescriptive linguistics tells people what should be in the language and tries to lay down rules to tell people how to use a language. Most modern linguistics is descriptive, whereas traditional grammars are prescriptive.4Immediate constituent analysis: The approach to divide the sentence up into its immediate constituents by using binary cutting until obtaining its ultimate constituents is called immediate constituent analysis. IC analysis is a hierarchical analysis showing the dif ferent constituents at dif ferent structural levels based on the distribution of linguistic f orms. The best way to show IC structure is to use a tree diagram. The f irst divisions or cuts are known as the immediate constituents(ICs), and the f inal cuts as the ultimate constituents(UCs).5Assimilation:Sounds belonging to one word or one syllable can cause changes in sounds belonging to neighboring words or syllables. As the f ollowing sounds bring about the change, this process is called regressive assimilation.e.g. a vowel becomes [+nasal] when f ollowed by a [+nasal] consonant.6Phonetics: The study of linguistic speech sounds that occur in all human languages , how they are produced, how they are perceived, and their physical properties, is called phonetics. The task of phonetics is to identif y what are speech sounds in a language, and then to study their characteristics. It includes three main areas: articul atory phonetics, acoustic phonetics, and auditory phonetics.7 Phonology: It is the description of the systems and patterns of speech sounds in a language. It is based on a theory of what every speaker of a language unconsciously knows about the sound patterns of that language. 8 Allophone is a phonetic variant of a phoneme in a particular language.9Recursiveness：It refers to the rule which can be applied repeatedly without any def inite limit. The rules introducing prepositional phrases also introduce the important concept of recursion.10 Stress: The prominence given to certain sounds in speech. When a word has more than one syllables, one of them will be pronounced with more prominence than others. This brings us to another speech sound phenomenon, that of stress. When a word belongs to dif ferent word classes, the stress of the word will be sometimes placed on diff erent syllables. When all the words above are stressed on thefirst syllables, they are nouns, but if they have the second syllables stressed, the words become verb s. Stress may also have af unction at the sentence level. In this case, the phonetic f orm of word stress may be show which part of sentence is in f ocus.11Morphology: is thus the study of the internal structure, f orms and classes of words, intended structure relevant rule f or word f ormation.12Allomorph: An allomorph is a member of a set of morphs which represent the same morpheme. Allomorphs are phonological or orthographic variants of the same morpheme. Allophones are in complementary distribution, allomorphs are also in complementary distribution, that is to say, they cannot occur in the same environment. e.g. -s, -es, and -en are all allomorphs (in writing) of the plural morpheme.13Derivation: the f ormation of new words by adding aff ixes to other words or morphemes in morphology and word f ormation.14Acronym: words which are composed of the first letter of a series of words and are pronounced as single words. Exmples: NATO, radar and yuppy.15blending: A single new word can be f ormed by combining two separate f orms. Typically, blending is finished by taking only the beginning of one word and joining it to the end of another word. For example, brunch is f ormed by the shortened f orms of breakfast and lunch.16Compounding:is the f ormation of new words by joining two or more stems. We have three types of compounds: 1, noun compounds:noun+noun: armchair, rainbow; 2, verb compounds: verb+verb: to sleep-walk; 3, adjective compounds: verb+adjectives: stir-crazy17Root: Some morphemes like car, talk, f riend and tour can stand alone as words. Such morphemes are called f ree morphem es. A word must contain an element that can stand by itself, that is a free morpheme, such as talk. Such an element is called a root. remains when all aff ixes are stripped from a complex word, e.g. system f rom un- + system + atic + ally. 18Minimal pairs and sets: The phonologist is concerned with what differences are signif icant, or technically speaking, distinctive. A distinctive diff erence is one that brings about the change of meaning. In order to determine which are distinctive sounds, the customary practice is to set up minimal pairs-pairs of words which differ from each other only by one sound.19Stem: A “stem” is any morpheme or combination of morphemes to which an aff ix can be added. It may be the same as , and in other cases, dif ferent from, a root. For example, in the w ord “f riends” , “f riend” is both the root and the stem, but in the word “f riendships”, “f riendships” is its stem, “f riend” is its root. Some words (i. e., compounds ) have more than one root ,e.g., “mailman” , “girlf riend” ,ect.20Suffix: Af f ixes can be joined to the end of the root or stem, in which case they are called suff ixes.An “affix” is the collective term f or the type of f ormative that can be used, only when added to another morpheme(the root or stem). Aff ixes are limited in number in a language, and are generally classif i ed into three subtypes: pref ix, suff ix and inf ix, e. g. , “mini-”, “un-”, ect.(pref ix); “-ise”, “-tion”, ect.(suff ix).21Syntax: the term used to ref er to the structure of sentences and to the study of sentence structure.22IC analysis: the approach to divide the sentence up into its immediate constituents byusing binary cutting until obtaining its ultimate constituents. 23Semantics: the study of linguistic meaning.24Sense: the inherent part of an expression’s meaning, to gether with the context, determines its ref erent. 25Reference: (in semantics) the relationship between words and \ the things, actions, events and qualities they stand f or. An example in English is the relationship between the word tree and the object “tree” (ref erent) in the real world.26Seven types of meaning: Conceptual meaning; thematic meaning ; connotative meaning; social meaning; affective meaning；ref l ective meaning; collocative meaning;后5种称associ ative meaning27Lexical gap: the absence of a word in a particular place in a semantic field of a language. For instance, in English we have brother versus sister, son versus daughter, but no separate lexemes f or “male” and“f emale” cousin.28Pragmati cs: can be def ined as the study of languages in use. It deals with how speakers use languages in ways which cannot be predicted f rom linguistic knowledge alone, and how hearers arrive at the intended meaning of speakers. In a broad sense, pragmatics studies the principles observed by human beings when communicate with each other. We can roughly say that pragmatics takes care of meaning that is not covered by semantics. So people use the f ormula as itsdef inition:PRAGMATICS=MEANING-SEMANTICS. 29Anaphora: a process where a word or phrase (anaphor) refers back to another word or phrase which was used earlier in a text or conversation.30Cohesion: the grammatical and/or lexical relationships between the different elem ents of a text. This may be the relationship between di ff erent sentences or different parts of a sentence.31Coherence: the relationship that links the meanings of utterances in a discourse or of the sentences in a text.32Prototype: what members of a particular community think of as the best example of a lexical category, e.g. f or some English speakers “cabbage” (rather than, say, “carrot”) might be the prototypical vegetable. 33 Prototype theory: a theory of human categorization that was posited by Eleanor Rosch. Following this theory, natural categories are organized according to prototypes which are considered as the most typical or representative of the category. A robin or sparrow is regarded as a prototype of the category of “bird”. People decide whether an entity belongs to a category by comparing that entity with a prototype.34iconicity: a feature of a language which means that the structure of language reflects in some way the structure of experience, that is, the structure of the world, including the perspective imposed on the world by the speaker. Caesar’s historic words “Veni, vidi, vici (I ca me, I saw, I conquered)” is a good case to prove the iconicity of order(the similarity between temporal events and the linear arrangement of elements in a linguistic construction). Iconicity of distance a ccounts f or the fact that things which belong together conceptually tend to be put together linguistically, and things that do not belong together are put at a distance. This entails that conceptual distance corresponds to linguistic distance not merely physical distance. eg: a, I killed the chicken. b, I caused the chicken to die. Iconicity of complexity: The phenomenon that linguistic complexity ref lects conceptual complexity is usually called iconicity of complexity.35Reflective meaning: is the meaning which arises in cases of multiple conceptual meanings, when one sense of a word f orms part of our response to another sense. Ref lective meaning is the product of people’s recognition and imagination.36Ambiguity: It refers to the phenomenon that an expression has more than one meaning. Two diff erent types of ambiguity can be distinguished on the basis of what is causing it: lexical ambiguity (more than one word meaning) and structural ambiguity (more than one synt actic structure) 37The diacritics: are additional symbols or marks used together with the consonant and vowel symbols to indicate nuances of change in theirpronunciation38Complementary distribution: [p.pH] are two different phones and are varivants of the phoneme /p/such variants of a phoneme are called allophones of the same phoneme. In this case the allophones are said to be in complementary distribution, because they never occur in the same context. [p] occurred af ter [s] while [ph] occurs in other places.39syllable: A unit in speech which isof t en longer than one sound and smaller than a whole word.41 the difference between derivational affix and inflectional affix (1)Inf lectional aff ixes very of t en add a minute or delicate grammatical meaning to the stem. E.g. toys, walks, John’s, etc. In contrast, derivational aff ixes of ten change the lexical meaning.E.g. cite, citation, etc.(2)Inf lectional aff ixes don’t change the word class of the word they attach to, such as flower, flowers, whereas derivational aff ixes might or might not, such as the relation between small and smallness f or the f ormer, and that between brother and brotherhood f or the latter. (3)In English, inf lectionalaff ixes are mostly suffixes, which are always wordf inal. E.g. drums, walks, etc. But derivational aff ixes can be prefixes or suffixes. E.g. depart, teacher, etc.定义：Derivational morphemes which are used to make new words in the language and are of ten used to make words of a di ff erent grammatical category from the stem Inflectional morphemes, which are not used to produce new words, but rather to show aspects of the grammatical f unction of a word.。

Actually, all bodies are either elastic or plastic and will be deformed if acted upon by forces .When the deformation of such bodies is small,they are frequently assumed to be rigid,i.e, incapable of deformation,in order to simplify the analysis.A rigid body is an idealization of a real body. （P2页第4段）
