I have marked in italics the things I "think" are wrong....
Australia, Great Britain and the United States of America all speak basically the same language. But (However,) you simply have to visit each country to realize that, while(whilst) they all speak English, its (itâs) far from the same language. The English spoken in Great britain(Britain), America and Australia has(have) many similarities, but a surprising number of differences as well. The main reason for this is the vast distance between each country.
Pronunciation between the three types of English is very unsimilar (different). In American English the "r" at the end of the word almost always affects its pronunciation, whereas in Australian and British English the "r" is often silent. (Also) The emphasis placed on the syllables of the word varies from British, Australian and American English. In Britain, the word âadultâ has the emphasis on the first syllable, whereas in America it is placed on the second half of the world (word). Australian English is unique in the fact that many words have sounds that are eliminated. Instead of saying âgood dayâ, the Australian speaker says âg'dayâ. The main pronunciation difference (differences) between the three forms, however, is (are) the pronunciation of the vowel sounds.
