　　要点分析和参考译文

　　要点：句子主干有两个并列的谓语部分，即" is contrary to……and is contrary to……。" 词组mercy killing 是对前面内容的概括。for which the medical profession stands 是"that"的定语从句。
　　参考译文：有意识的结束一个人的生命——安乐死——既违反了医学界的职业立场，也违反了美国医学会协会的宗旨。

　　要点：此句的主干是一个由and 连接的并列结构。第一部分有几个并列祈使句组成，第二部分是一个完整的主谓结构，全句主干即"Put…exalt…，forever free … strife and you have a future…colors of hope.由于第一部分并列祈使句较长而第二部分较短，而且连接两部分的and前面有存在着另外一个and（need and strife）从而致使句子的结构较复杂，不易看出主干的并列结构。
　　参考译文：把这一切集合起来，加以提高，使之超越现存的缺点，再加上人类得到拯救的憧憬，永远无求无争，那么你将有一个闪耀着希望的绚丽多彩的未来。

　　要点：全句为并列复合句。 "and"连接并列句。第二个句子是主从复合句。"which"引出非限制性定语从句，修饰"area"."that " 引出限制性定语从句，修饰 "villages"."what" 引出名词从句作"form"的宾语
　　参考译文：三百多万人口居住在伦敦市区，将近五百多万人口居住在周围的郊区——这些郊区由原来分散的村庄构成，逐步形成如今被称为的外伦敦。
