While academics have an intuitive knowledge of what consti- tutes good academic prose, this knowledge is seldom articulated explicitly and much less often brought to the attention of students. Students are usually only instructed in general terms, if at all, as to the requirements of their written work. These instructions usually ex- tend to advice on the required content of macrostructural components such as the follow- ing which might be required in an experimental report: Introduction, Methodology, Results and Discussion. They may require that the arguments be logical and consistent but rarely do they elaborate on how these instructions are to be carried out or advise on what kinds of sentences can carry what sort of information or on the ordering of items of information. (Kalder et al. 1996:1) A key concept in the understanding of intersentential relations is that of rhetorical func- tion. In this Report, Grace Wong uses Rhetorical Function Analysis as a tool to construct a ‘rhetorical map’ of a text to provide a diagrammatic network of the hierarchies of rela- tionships, and thus show its patterns of coherence and cohesion. With data from the writing of Hong Kong students in Hong Kong and in Australia, she shows that the latter group, after three years away from their home environment, “were able to produce longer essays, with more accurate tense forms and idiomatic ex- pressions …. [T]heir increased exposure to English has helped them to advance along the path of approximation toward the target language”. Wong points out, however, that many fossilised errors remain, and that the Hong Kong students in Australia still have difficul- ties in structuring their writing. As an exploratory step towards a longitudinal study of the interlingual acquisition of rhetorical functions, Wong’s Report provides valuable groundwork for further research of importance in language pedagogy.
