sentences:  Through the use of these complex sentence constructions with informationally vacuous subjects, English is able to maintain both a topic-comment sentence structure and a SVO syntax.Focus constructions emphasise a particular piece of new or salient information within a sentence, generally through allocating the main sentence level stress on the focal constituent.For example, "the girl was stung by a bee" (emphasising it was a bee and not, for example, a wasp that stung her), or "The girl was stung by a bee" (contrasting with another possibility, for example that it was the boy).
