The purposes of this study were to investigate types of sentences frequently used in business news, to investigate types and functions of postmodifires frequently used in each type of sentence in business news in the Bangkok Post, The Nation, USA Today, and The Guardian, and to synthesize patterns of postmodifiers used in each type of sentence. The corpus was 120 business news stories from four newspapers covering economics, marketing, commerce, industry, information technology, and property selected during April and June 2010. Frequency and percentage were employed for the data analysis.The study revealed that complex sentences were used most frequently in the Bangkok Post, USA Today, and The Guardian while simple sentences were used most frequently in The Nation. Prepositional phrases modifying noun phrases were used most frequently in simple, complex and compound-complex sentences in all the four newspapers studied. Regarding compound sentences, prepositional phrases modifying noun phrases were used most frequently in the Bangkok Post, The Nation, and USA Today while compound sentences in The Guardian included prepositional phrases modifying verb phrases at the highest percentage. News writers tended to place both phrase and clause postmodifiers, which occurred in series and included other types of embedded postmodifiers, in predicate part more than in the subject part. Prepositional phrases, present participial phrases, past participial phrases, and appositive phrases were frequently used in both parts but adverb phrases, and elliptical clauses were always placed at the end of the sentence. Simple and complex sentences included more varieties of postmodifier types than in compound and compound-complex sentences. The Bangkok Post and foreign news writers tended to use postmodifiers in similar ways.
