This need is enshrined in the concept of sustainable development, which means that we must, for the benefit of coming generations, leave enough environmental space so that these generations will be able to address their needs and fulfill their aspirations.
【译文】这一需求已被正式载入可持续发展的概念之中。所谓可持续发展是指：为了子孙后代的利益，我们必须保留足够的生存环境空间，以满足他们的需要，施展抱负。
【分析】句子的框架是This need is enshrined in the concept of sustainable development ...。其后紧跟着一个which引导的定语从句，修饰先行词sustainable development。此定语从句的谓语动词means又套嵌一个that引导的宾语从句，即we must ... leave enough environmental space。此宾语从句中又有so that结构做此从句的目的状语。be enshrined in意为“被深深地珍藏（或铭记）在…”，此处转译为主动语态“纳入到”。sustainable development译为“可持续发展”。

Levi Strauss persuaded the court that, by selling its jeans cheaply alongside soap powder and bananas, Tesco was destroying the image and so the value of its brands, which could only lead to less innovation and, in the long run, would reduce consumer choice.
【译文】利维斯特劳斯公司说服法庭，说乐购把利维牛仔裤与皂粉，香蕉等放在一起廉价销售，这一做法使其形象受损，品牌价值也因此受到了影响，这势必会使产品缺乏新意，最终减少消费者的选择。
【分析】that之后是一个宾语从句；by之后的动名词来做宾语从句的状语；宾语从句中which又引导了一个非限制性定语从句。

Minority youths arrested on violent felony charges in California are more than twice as likely as their white counterparts to be transferred out of the juvenile-justice system and tried as adults, according to a study released last week by the Justice Policy Institute, a research center in San Francisco.
【译文】旧金山的一个研究中心，刑法政策研究所，上周发表的研究结果表明，在加利福尼亚，因为犯重罪被少年法庭转出，而以成人的身份被审判逮捕的非白人少年，比白人少年的两倍还要多。
【分析】这是一个比较长的简单句。“more than twice as likely as their white counterparts”是一种表示倍数的表达方式；“to be transferred out of the juvenile-justice system and tried as adults”不定式短语来修饰white counterparts； “according to a study released last week by the Justice Policy Institute”做状语；“a research center in San Francisco”是“the Justice Policy Institute”的同位语。
