And now this death of a young woman by whom the world had remained shocked from the moment she first appeared before it, whose name contained the shadow of her end: Princess Di.

请问老师，这句话是省略了“there has come”的存在句吗？原型是这样吗：“And now there has come this death of a young woman ...”在什么情况下可以省略“there+谓语”？

Nothing to worry about.是属于这个结构吗？原型是这样吗：There is nothing to worry about.

【翻译】现在传来一位年轻女子死亡的这个消息，从她第一次公开亮相的那一刻起就一直令全世界感到震撼，她的名字隐含着她归宿的阴影。（注：黛安娜的昵称叫Di，与die“死亡”谐音。）

这不是一个完整的句子，缺少谓语。在主语this death之前，可以理解为省略了there has come。

【句子成分分析】

1. 句子主干：there has come this death of a young woman：传来了一位年轻女子死亡的消息。这样补充后，就成了“There + 不及物动词 + 主语” 结构。

2. 定语从句：by whom the world had remained shocked from the moment she first appeared before it，修饰a young woman。介词by + whom 提前，正常语序为：the world had remained（=been） shocked by whom：全世界因她而一直感到震撼。

3. from the moment she first appeared before it：介词短语表示时间，“从...那一刻起”。里面又包含一个定语从句：she first appeared before it（= the world），修饰the moment。

4. whose name contained the shadow of her end: Princess Di：非限制性定语从句，也是修饰修饰a young woman。可以单独翻译成一句。

此外，关于Nothing to worry about.不一定就是There is nothing to worry about.的省略。这要根据上下文判断，也可能是：You/We have nothing to worry about.
