The final group of examples all illustrate the relation of opposition as with the notions
‘continue’ and ‘cease’ contained in the words still and cease (cause endless trouble still
[2] and will cease to be a problem [17]), or in the complementary (or binary) pair
‘male’ and ‘female’ contained in husbands and wives in [8] and the employed–the
unemployed [10]. Examples of less exclusive forms of opposition are lunch–dinner [3],
lunch [3, 14–17] and lunch [6], dine–sup [5], bosses–workers [9]. Of the pairs of places
which are contrasted in [8–10], perhaps only boardroom and building site could be seen
as opposite in meaning (in terms of social class) outside of a specific context, while the
others (cafeteria–kitchen, in the pub–by the telly, restaurants–home) do not really exhibit
either striking similarity or opposition in meaning in isolation. Finally, a contrast seems
also to be involved in discourage lunch ‘stop people from wanting to go out to lunch’
and seem keen to go out to lunch [15–16].
Larger text patterns Certain vocabulary items have the function of linking larger
segments of text. Examples are problem, issue, approach, solution, difficulty, drawback
and question. The function of these procedural lexical items is to organize and structure
a text, to indicate the ‘larger text-patterns the author has chosen, and build up expecta-
tions concerning the shape of the whole discourse’ (McCarthy 1991: 76). The word trouble
in [2] has great cohesive power because it activates in the reader what has been called
the problem–solution pattern. The full pattern consists of the steps situation, problem,
response, result, evaluation. The word trouble makes the reader expect to be told at least
what the problem is and, possibly, how to resolve it. Sentence [2] is a brief statement
of the situation, and [3] and [7] through [12] give detailed descriptions of the problem.
An actual response to the situation, and its result, is mentioned in [15]. The final text
sentence [17] can be seen as a sort of evaluation. The problem–solution pattern, signalled
by trouble [2], difficulty [4] and problem [17], is thus a device which helps to establish
the unity of the text.
Among the conceptual, and more broadly semantic, relations that are often found in
argumentative texts, three are evident in the lunch test: opposition, value and reason (see
de Beaugrande and Dressler 1981: 184). The most important semantic relationship is that
of contrast or opposition. The most comprehensive contrast in our text is between the
harmful effects of lunch [7–11] and the useful functions it fulfils [13–16]. The pros and
cons also differ in degree. The lexemes indicating a positive evaluation (and thus real-
izing the conceptual relation of value), handy, convenient and continuing solace [13]
express a low or middling degree, while the negative evaluations are located near the
middle or the top of the scale: endless trouble [2], difficulty [4], social divider of infinite
power [7], a whole clutch of restaurants . . . meals customers would never dream of eating
[11], festival of cholesterol [12], problem [17].
Englishmen in general are set in opposition to one another in [3] and in [8] to [10].
In [17] the English are contrasted with the French. A further series of contrasts clusters
around the concept of lunch. Elaborating on the contrast between word and thing in [2],
the author first mentions the changes in the meaning of the word in [4] and [6] before he
proceeds to detail the differences in the thing itself, using places and foods to point
up the contrast in [8] to [10]. The final contrast is between the action (discourage [15])
and the state (be keen [16]). The frequency of semantic contrasts on the levels of concepts,
lexical items and text sentences reflects a view of lunch as something which creates
