1. Some have breathed sighs of relief, others, including churches, right-to-life groups and the Australian Medical Association, bitterly attacked the bill and the haste of its passage. But the tide is unlikely to turn back.

【譯文】一些人如釋重負，另一些人，包括教會、生命權(quán)利組織以及澳大利亞醫(yī)學(xué)會成員都對這一決議及其倉促的通過進行了猛烈抨擊。但是這一潮流已經(jīng)不可能逆轉(zhuǎn)。

【析句】第一句由兩個表示對比的句子組成：Some have breathed… others… bitterly attacked…，其中others之后是介詞詞組（including churches，right-to-life groups and the Australian Medical Association），作others的同位語。 its passage中的its指代前面提到的the bill。第二句與第一句是轉(zhuǎn)折關(guān)系。

【講詞】tide本意是“潮水，潮汐”，句中的含義是“趨勢，趨向”。turn the tide意為“使形勢轉(zhuǎn)變，改變局面”。We are going in the wrong direction and need the government to help turn the tide.（我們犯了方向性錯誤，我們需要政府改變這一形勢。）

2. In Australia—where an aging population, life-extending technology and changing community attitudes have all played their part—other states are going to consider making a similar law to deal with euthanasia.

【譯文】在澳大利亞，出于人口老齡化、延長壽命技術(shù)和公眾態(tài)度的變化等原因，其他的州也在考慮通過類似的法律來解決安樂死的問題。

【析句】這個句子的主體結(jié)構(gòu)是other states are going to consider making a  similar law to deal with euthanasia。句首的In Australia是地點狀語，后面跟了一個定語從句（where an aging population, life-extending technology and changing community attitudes have all played their part），進一步解釋Australia的具體情況。

【講詞】play a part意為“發(fā)揮或起到作用”。The US must play its part in abolishing tariffs or the earth summit will fail.（美國必須采取行動廢除關(guān)稅，否則地球峰會就將失敗。）France is ready to play its part in enhancing India's nuclear status.（法國正準(zhǔn)備盡力加強印度的核地位。）
