结构分析: 本句主干结构为researchers ... have began to extend that forecast...;逗号前面为状语成分，包含一个when引导的定语从句，其中it是形式主语，appear后面是that引导的是主语从句;

译文: 虽然一开始在20世纪60年代和70年代有过一段乐观的时期--那时候仿佛晶体管电路和微处理器的发展将使它们在2010年能够模仿人类大脑的活动--但是最近研究人员已经开始将这个预测延后数十年，甚至数百年。

7. Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect" , a centuries-old moral principle holding that an action having two effects - a good one that is intended and a harmful one that is foreseen - is permissible if the actor intends only the good effect.

结构分析：句子主干是：... the Court ... supported the medical principle of "double effect" ... ; although引导的让步状语从句，其中包含一个that引导的宾语从句，作ruled的宾语;a centuries-old moral principle是the medical principle的同位语，其中包含一个现在分词holding及其宾语从句现在分词短语做定语;宾语从句中，主干部分是：an action ... is permissible... ，其中having是现在分词作定语，修饰an action;两个破折号之间是对two effects的解释说明;宾语从句中还包含一个if引导的条件状语从句;

译文：尽管裁决认为，宪法没有赋予医生帮助病人自杀的权利，然而最高法庭实际上却认可了医疗界的“双效”原则，这个存在了好几个世纪的道德原则认为，如果某种行为具有双重效果(希望达到的好效果和可以预见得到的坏效果)，那么，只要行为实施只是想达到好的效果，这个行为就是可以允许的。
