1. Does your representation of “time line” coincide with the representation described in the text?

2. What philosophically relevant aspects of time do not have a bearing on tense distinctions?

3. What are the three parameters thought to be relevant in identifying tense distinctions?

4. Which of the three parameters is not grammaticalised as tense?

5. In what way is this parameter (not grammaticalised as tense) expressed in languages? Do these linguistic means of expression depend on culture?

6. Does the description of speech situations refer to logical conceptualization or linguistic expression? Prove your point.

 

3. Choose the correct variant.

 

1. “Temporal” is the corresponding adjective for

 

- time +

- tense

- tempo

 

2. The present moment is

- a short stretch of time (only the moment when the speaker pronounces the utterance)

- a shorter or longer stretch of time +

- a period of time when the utterance holds true

 

3. The difference between “absolute” and “relative” tenses lies in

- the speaker’s attitude to the situation (whether they see the situation as real or unreal)

- the location of the deictic center (whether the deictic center is located at the present moment or at a different point in time) +

- the location of the situation with respect to the deictic center (whether the situation is prior to, subsequent to, or simultaneous with the deictic center)

 

4. The time line is conventionally represented as

- curvy

- going upwards

- straight +

 

Expressions of 'tense'

 

Location in time can be achieved linguistically in many different ways ranging from purely lexical to grammatical. Comrie (1985:8-9) suggests grouping them in three classes:

Lexically composite expressions - these involve slotting time specifications into the positions of a syntactic expression, e.g. the English five minutes after John left, 10-45 seconds after the Big Bang, the day before yesterday, last year. This set is potentially infinite in a language that has linguistic means for measuring time intervals.

Lexical items - these include items such as: the English now, today, yesterday; the Czech loni 'last year'. The range of time distinctions captured through single lexical items is necessarily smaller than that which is possible using lexically composite expressions, as it depends on the stock of items listed in the lexicon in the given language.

Grammatical categories - this is the set of grammaticalised expressions of location in time, that is the set of tenses in the given language. This set is the smallest of the three, with a finite number of synchronically listed items (tense values), and it is possible that for some languages it may contain no items, as there may be languages with no grammatical category of tense.

In order to be regarded as a (grammaticalised) tense, the expression of location in time has to be integrated into the grammatical system of the language. In contrast, a lexicalised expression of the location in time indicates its integration into the lexicon of the language, but does not entail any necessary consequences for the language's grammatical structure. Grammaticalisation, as opposed to lexicalisation, of the location in time, correlates with two parameters: obligatory expression and morphological boundness. The very rough rule is that a tense is grammaticalised if its morphological expression is obligatory even if the information carried by the exponent is redundant. For example, in the English sentence Last year I bought a new car "the choice of a tense other than the simple past would make the sentence anomalous, although the information that the event took place in the past is expressed unambiguously by last year" (Dahl & Velupillai 2005:266). The obligatoriness of tense can also be demonstrated in languages which allow for tense marking to be omitted in some circumstances. This has been argued for Central Alaskan Yup'ik whose tense system is relative (the deictic centre can shift even within one sentence between the time of speech and another reference point) and where the absence of an overt tense suffix has to be recognised as a meaningful zero (Mithun 1999). Morphological boundness is perhaps a slightly more problematic criterion, which is not necessary in itself - as in Yemba (Niger-Congo), where tense is expressed primarily by means of auxiliaries (i.e. not bound morphemes) which are also clearly not separate lexical items which could be seen as contributing to the compositional meaning of tense (Comrie 1985:11).



Tense is typically a morphological category of the verb, or verbal complex, and it can be expressed either by verbal inflection (on the main verb or the auxiliary - as in English), or by grammatical words adjacent (ęîňîđűĺ ďđčěűęŕţň) to the verb (such as the Yemba tense auxiliaries; see above). It can also be analysed as a grammatical category of the clause. Anderson (1992) classifies tense as 'phrasal inflection' (distinct from 'configurational inflection' such as case, 'agreement inflection' such as number concord on English verbs, or 'inherent inflection' such as gender on Latin nouns), because it is a property that is "assigned to a larger constituent within a structure" (a clause) but "realized on individual words" (verbs). Similarly, Booij (1994:30) argues that tense has scope over a whole clause (however, he classifies it as 'inherent inflection', opposed to 'contextual', because "the tense of the verb is not determined by syntactic structure". It is, therefore, not unexpected that tense can also be expressed by a marker placed in the position of sentence particles (as in the sentence-second position in Warlpiri, Australian; Hale 1973, cited in Comrie 1985:12), that languages may allow multiple marking of the tense value on different elements in the same clause or that tense systematically does not occur on non-finite verb forms.

Finally, it is important to note that there is often no agreement between scholars about the classification of individual grammatical forms, especially when the verbal forms and constructions simultaneously involve semantic elements from different domains, typically those of aspect and mood (see Dahl 1985), but also case (e.g. in Australian languages - see Evans 1995; 2003) and other categories. In fact, there are seldom grammatical markers that express just the temporal location of the situation.

1.1 What's new in the Assembler material

 

After of one year that we've released the first Assembler material on-line. We've received a lot of e-mail where each people talk about different aspects about this material. We've tried to put these comments and suggestions in this update assembler material. We hope that this new Assembler material release reach to all people that they interest to learn the most important language for IBM PC.

 

In this new assembler release includes:

 

A complete chapter about how to use debug program

More example of the assembler material

Each section of this assembler material includes a link file to Free

On-line of Computing by Dennis Howe

Finally, a search engine to look for any topic or item related with this updated material.

 

 

1.2 Presentation

 

The document you are looking at, has the primordial function of introducing you to assembly language programming, and it has been thought for those people who have never worked with this language.

 

The tutorial is completely focused towards the computers that function with processors of the x86 family of Intel, and considering that the language bases its functioning on the internal resources of the processor, the described examples are not compatible with any other architecture.

 

The information was structured in units in order to allow easy access to each of the topics and facilitate the following of the tutorial.

 

In the introductory section some of the elemental concepts regarding computer systems are mentioned, along with the concepts of the assembly language itself, and continues with the tutorial itself.

 

 

1.3 Why learn assembler language

 

The first reason to work with assembler is that it provides the opportunity of knowing more the operation of your PC, which allows the development of software in a more consistent manner.

 

The second reason is the total control of the PC which you can have with the use of the assembler.

 

Another reason is that the assembly programs are quicker, smaller, and have

larger capacities than ones created with other languages.

 

Lastly, the assembler allows an ideal optimization in programs, be it on their size or on their execution.

 

 

1.4 We need your opinion

 

Our goal is offers you easier way to learn yourself assembler language. You send us your comments or suggestions about this 96' edition. Any comment will be welcome.
