例220　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.

【结构分析】句子开头是个介词短语做状语，也就就是In Australia，后面是个插入语，也是定语从句修饰Australia，该定语从句的主语an aging population, life-extending technology and changing community attitudes，动词是have all played，宾语是their part，后面是个句子真正的主干，也就是other states are going to consider making a similar law to deal with euthanasia。

【亮点回放】此句话的亮点在于超级定语从句的使用，是where引导的，很长，很有气势。

【核心词汇】

an aging population　人口老龄化

life-extending technology　延长寿命的技术

changing community attitudes　变化的社会态度

deal with　应对

euthanasia　安乐死

【参考译文】在澳大利亚——人口老龄化，延长寿命的技术和变化的社会态度，这些因素都在发挥作用——其他的州也会考虑制定相似的关于安乐死的法律。
