This dissertation investigates the interaction between the basic rules for tense interpretation, on the one hand, and temporal types of VPs or sentences, time expressions and syntactic distribution of tense forms, on the other. This dissertation proposes an analysis in which each tense form is associated with at least three time identities, the zero time point, the event time and the reference time. The zero time is defined as the time from which a situation is considered and interpreted, the event time as the time at which a situation takes place and the reference time is the time at which the situation holds and which is part of the event time under consideration. Concerning the temporal structures of situations expressed by VPs or sentences, this dissertation proposes a six-type temporal classification and treats temporal types not as atomic but as reducible to temporal features. By so doing, this dissertation brings to light the internal structure among various temporal types. Regarding the relation between tense and time expressions, this dissertation analyzes it to be one of temporal inclusion and provides a successful account of why time adverbs do not necessarily mark both ending points of a given homogeneous situation, though this is true with a nonhomogeneous situation. In accounting for tense interpretation in complement clauses, this dissertation maintains that complement tense forms and matrix tense forms can be interpreted in the same way and they differ only in the interpretation of the zero time point. In the matrix clause, tense is interpreted with respect to the speech time and, in the complement clause, tense is interpreted relative to the reference time of the matrix clause. Because the zero time is used instead of the speech time in the proposed basic tense rules, these rules are general and powerful enough to be applicable to tenses in any syntactic environment.

This study examines the forms and meanings of tensed and non-tensed clauses in English, and proposes an analysis of them that is 'Reichenbachian' in spirit and syntactic in orientation. The study considers tensed verb forms in simple sentences, focussing on 'present', 'future', and 'perfect' forms and their interaction with adverbials of temporal location; and those in complement, relative, and temporal clause constructions. It also considers three types of non-tensed verb forms--infinitives, gerunds, and 'bare infinitives'--in verb complements. / The study demonstrates that the interpretation of tensed and non-tensed forms can be described in terms of Reichenbach's (1947) temporal schemata, which express relations between 'S' ('speech time'), 'R' ('reference time'), and 'E' ('situation time'). However, its central claim is that the tensed forms themselves are 'temporally underspecified', encoding relations between 'S' and 'R', and leaving the relation between 'R' and 'E' and the location and duration of both of these intervals to be determined by lexical properties of the verb and its arguments, temporal adverbials, and context. Non-tensed verbs forms have a similar syntactic representation, differing primarily in not fully encoding a relation between 'S' and 'R'. This claim is cashed out in terms of two devices: a feature system that expresses tenses as particular values of the feature matrix (Anterior, Posterior); and a device of 'tense linking', based on Higginbotham's (e.g. 1983) proposal for binding theory, which associates verbs with temporal adverbials or tensed Infl, and one (tensed or non-tensed) Infl with a higher one.

Even though there has been little agreement as to how the phenomenon of serialization is to be defined, it is generally assumed (i) that there is a close meaning dependency (of some kind) between the event descriptions serialized (serials hereafter), (ii) that the serials cannot be modified independently by such sentential operators as tense, aspect, mood, etc., and (iii) that these aspects of serialization are closely related to the fact that a serial construction refers to a `single event'.However, these assumptions have not been materialized into an explicit analysis of serialization. In particular, it has not been clearly accounted for how the concept of single event is attributed to the meaning dependencies between serials that are apparently so diverse as to defy a unique semantic characterization. Thus, in previous studies, the apparent heterogeneity of meaning dependencies has led to `fragmentation' of serialization into coordinating and subordinating types, and of the subordinating type, in turn, into a variety of lexically governed subtypes.This dissertation argues against such fragmentation and provides a unified semantic analysis of serialization, drawing on the philosophical discussions of event individuation and causation. Under my analysis, the sense of inseparable connection between serials is represented by a counterfactual dependency between them. The counterfactual dependency only entails that the first serial is necessarily related to the second, without specifying the nature of the necessary relatedness. Thus, the variety of meaning dependencies observed in the literature can be accommodated as particular instances of the counterfactual dependency.Moreover, the single event reading of serialization is attributed to the `counterfactual' dependency between serials: in virtue of the dependency, the serials are not identified independently of each other, and hence are construed as constituting a single event unit. A variety of structural constraints on serialization observed in the literature are then analyzed as natural consequences of the conceptual unity of the serialized events as a whole. / Department of English

The purpose of the study was two-fold. First, it investigated, described, and analyzed tense shifts and the roles of the present tense forms in IEIL autobiographical discourse. Second, as a contribution to the study of English interlanguage of Indonesian EFL learners it presents some pedagogical implications for the EFL teaching and learning in Indonesia and offers suggestions for further research. The data used for the study were twenty-six essays containing 1700 verb phrases in 937 sentences, which were written by twenty-six freshman EFL learners of the University of Sriwijaya in Palembang, Indonesia, in 1986.The results of the study show that tense use in IEIL is systematic, on one hand, and variable, on the other. Shifts of tense from past to present are generally predictable. The present tense usually functions to present the writer's evaluation or opinion, habitual occurrences, general truth, or factual descriptions functioning as permanent truth in relation to the writer's childhood. Occasionally, the present tense functions as the Historical Present to narrate past events. The past tense, on the other hand, usually functions to describe past truth and, at times, to narrate historical events such as the writer's date and place of birth.Variability also characterizes IEIL autobiographical discourse. That is, IEIL writers do not completely follow the present and past tense rules. For instance, they usually use the present tense to express habitual occurrences, but at other times they use past tense accompanied by such expressions as "on Sundays," "on holidays," "whenever," etc.In addition, the following conclusions have been drawn: (1) IEIL autobiographical discourse largely contains description expressed in the past tense; (2) discourses are highly recommended to be used as the first material in teaching linguistic phenomena such as tense shifts to Indonesian EFL learners; and (3) following the IL theory and principles, EFL teachers should not treat EFL learner's should treat them as a sign that they are in fact in the process of learning.deviants as a sign of improper usage and harmful but instead should treat them as a sign that they are in fact in the process of learning. / Department of English

On the basis of an investigation of a corpus of 5.5 million words, this thesis analyses the use of the present perfect in modem American and British English. The investigation traces the development of the present perfect from its origins as a structure with adjectival meaning to its modern-day use as an aspectual verb form. A frequency analysis tests the claims of various writers that the present perfect is losing ground against the preterite and is less frequent in American than in British English. Neither claim is supported by the results of this analysis. A temporal specifier analysis investigates the co-occurrence of a large number of adverbials with the various verb forms. It finds that certain groups of specifiers which have hitherto been considered markers for the present perfect are in fact very poor indicators. Specifiers indicating a period of time lasting up to the moment of utterance, however, are found to be very reliable indicators. With one exception no significant difference was found between the British and American corpora in this respect. A functional-semantic analysis examines the various theories of the present perfect against the background of the results of the empirical investigation and finds them to be insufficient in one or more respects. In the final chapter the division between tense and aspect is shown to be artificial and a model of the present perfect is presented which is based on the idea of multilayered aspectual values. The model is centred on the unifying concept of phragmatisation - the closing of the event time-frame. According to this model, discourse topics involving the present perfect are perceived to describe an event which takes place in a time frame which is not closed to the deictic zero point at the moment of utterance. The final section describes which factors are operative in the phragmatisation or closing of event time frames.

English exhibits a rich apparatus of tense, aspect, time adverbials and other expressions that can be used to order states of affairs with respect to each other, or to locate them at a point in time with respect to the moment of speech. Ideally one would want a semantics for these expressions to demonstrate that an orderly relationship exists between any one expression and the meanings it conveys. Yet most existing linguistic and formal semantic accounts leave something to be desired in this respect, describing natural language temporal categories as being full of ambiguities and indetenninacies, apparently escaping a uniform semantic description. It will be argued that this anomaly stems from the assumption that the semantics of these expressions is directly related to the linear conception of time familiar from temporal logic or physics - an assumption which can be seen to underly most of the current work on tense and aspect. According to these theories, the cognitive work involved in the processing of temporal discourse consists of the ordering of events as points or intervals on a time line or a set of time lines. There are, however, good reasons for wondering whether this time concept really is the one that our linguistic categories are most directly related to; it will be argued that a semantics of temporally referring expressions and a theory of their use in defining the temporal relations of events require a different and more complex structure underlying the meaning representations than is commonly assumed. A semantics will be developed, based on the assumption that categories like tense, aspect, aspectual adverbials and propositions refer to a mental representation of events that is structured on other than purely temporal principles, and to which the notion of a nucleus or consequentially related sequence of preparatory process, goal event and consequent state is central. It will be argued that the identification of the correct ontology is a logical preliminary to the choice of any particular formal representation scheme, as well as being essential in the design of natural language front-ends for temporal databases. It will be shown how the ontology developed here can be implemented in a database that contains time-related information about events and that is to be queried by means of natural language utterances.

This data study concentrates on the past tense marking in the interlanguage (IL) of Chinese speakers of English. Following the assumptions of Hawkins & Lizska, (2003), it is assumed that unlike native speakers of English, Chinese speakers of English have a higher level of optionality within the past tense marking of their grammars. It is claimed that the primary reason for this occurrence is the lack of the functional feature T(ense) [+/-past] in Mandarin Chinese. If a particular functional feature is missing in a learner's L1 grammar, it is thought that it will be absent in one's L2 grammar as well. Three advanced Chinese speakers of English were tested on the past tense marking in their IL production. Both spontaneous oral and reading speech were used for this data analysis.
