found in the appendices on pp. 167 to 170. The text rhetorical development realization was done through the analysis
of the text clauses which is suggested by Halliday 1994 with his three strands of meanings which was explained thoroughly on pp. 74 to 96 of this dissertation.

th
,2006 the government of Indonesia recommended English textbooks published by fourteen 14 publishers which can legally be used
by senior high school students for they had been proved to have satisfactorily good quality after being evaluated thoroughly Kompas, January 12, 2006. The
evaluation involved professionals such as selected teachers, lecturers, and linguists through out Indonesia, and each textbook was evaluated five times by
different evaluators. Six out of those recommended textbooks are used as the data sources. The consideration of using them as the data sources is due to some
reasons. First, as they are recommended, the tendency to be used by schools in Indonesia is great; second, their scope of use is very large, that is throughout
Indonesia; and finally, their reading texts realizations have not been analyzed yet. The choosing of six textbooks as the sources of data was done
purposively, that is by taking into account the following purposes: 1.
to include the textbooks used by all the SHS grades, the choices of textbooks should consist of the ones used for the tenth, eleventh and
twelfth grades of SHS. As the chosen textbooks are six, two textbooks are nominated for every grade.
2. to provide variability the nominated textbooks should be published by
different recommended publishers. It means six various textbooks get a chance to be analyzed in terms of their respective reading texts.
