answers with the whole class.students should keep in mind the following pattern sound formal and emphatic.sentences begin with a word that has a negative meaning.sentences have the word order of a question (inversion).t: please remember the grammar rules. there are a number of ways to add emphasis to your sentences in english. use these forms to emphasize your statements when you are expressing your opinions, disagreeing, making strong suggestions, expressing annoyance, etc. please look at the following. show the following on the powerpoint.inversion invert the word order by placing a prepositional phrase or other expression (at no time, suddenly into, little, seldom, never, etc.) at the beginning of the sentence followed by inverted word order. examples: at no time did i say you

is followed by the main verb. emphaticadd “do” as auxand mark it for tense. this pattern is used to correct an incorrect statementor assumption by someone else.examples: marla did buy a rabbit.(base sentence: marla bought a rabbit.)i did give it back to you when i got home from camping.i do tidy it.cleft sentences: it sentences introduced by it is or it was are often used to emphasize a specific subject or object. the introductory clause is then followed by a relative pronoun. examples: it was i who received the promotion. it is the awful weather that drives him crazy. cleft sentences: what sentences introduced by a clause beginning with what are also used to emphasize a specific subject or object. the clause introduced by “what” is employed as the subject of the sentence as is followed
