ABSTRACT
So, for the present tense of be we have short forms for all persons:
I am /a m/ I’m /ɑim/ you are /ju: ɑ:r/ you’re /jɔ:r/ he is /hi: z/ he’s /hi:z/ she is /ʃi: z/ she’s /ʃi:z/ it is /t z/ it’s /ts/ we are /wi: ɑ:r/ we’re /wər/ they are /ðε ɑ:r/ they’re /ðεər/
Pay attention to the pronunciation of these short forms in British English, and notice that all the full forms have two syllables, while the short forms all have one.
