2. The Use of Strong Forms As i have said, these common words which have weak forms also have strong forms. The strong forms are used in the following cases 1)When the word is stressed, e.g They dont believe, do they? /Oei ' daunt bi'li v 'dur oei/ You must choose us or them. /ju: mast tu: z'As 2: "dem 2)When the word is at the end of a sense group or a sentence, even when they are unstressed. e.g What are you looking at? /wot a ju: ' lukin aet/ 3)Prepositions may have their strong foms when they are followed by an unstressed personal pronoun at the end of a sense group or a sentence. However, in this position the weak form may also be used. For example I am waiting for you. /aim'weitin f: ju or /aim'weitin fa ju 4) The indefinite pronoun“some” in the meaning of“ a certain quantity” is always stressed and therefore pronounced /s a m/. For example some of us /'s a m av as/ The adjective"some"in the meaning of"certain"always use its strong form, even when it is unstressed.E.g For some reason she is absent today /f: sA 'ri zn iz'aebsnst ta'dei/ As an adjective in contrast to"others"it is al ways stressed and therefore pronounced/s A m/.E. g Some people like it, but others dont /'s A m pi: pl laik it batA Oaz 'daunt/2.The Use of Strong Forms As I have said, these common words which have weak forms also have strong forms.The strong forms are used in the following cases: 1)When the word is stressed,e.g. They don’t believe, do they? /ðei 'dәunt bi'li:v 'du:ðei / You must choose us or them. /ju: mәst 'ʧu:z 'Λs ɔ: 'ðem / 2) When the word is at the end of a sense group or a sentence, even when they are unstressed.e.g. (Who is on duty today?) ---- I am./'ai æm/ What are you looking at? /'wɔt ә ju: 'lukiŋ æt/ 3) Prepositions may have their strong forms when they are followed by an unstressed personal pronoun at the end of a sense group or a sentence.
