I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an ?Australian car and has gone to ?Alice Springs, a small town in the centre of Australia.He will soon visit Darwin. From there, he will fly to Perth. My brother hasnever been abroad before, so he is finding this trip very exciting.

Australia /?'streilj?/ s 后的tr 應該濁化谅畅，讀dr欲间，我只是記得s后的清輔音要濁化麻惶，不過這會兒百度了一下，知乎里有這段話供參考，英音和美音有差別踪旷，查了下覺得是這樣，如果單詞開頭就是s+清輔音，該清輔音必然濁化鲤妥。如果句中出現，s+清輔音的音節(jié)如果重讀（有重音符號 ’）那么美音一般都濁化拱雏，英音不濁化棉安，不過有時也不一定。
