网友应该提供完整的句子。上面的as it did in the case of Alfred Bloggs who worked as a dustman for the Ellesmere Corporation，仅是一个“比较状语从句”。全句应该是：

This can give rise to curious situations, as it did in the case of Alfred Bloggs who worked as a dustman for the Ellesmere Corporation.

【翻译】这常常会引起种种奇怪的现象，在艾尔斯米尔公司当清洁工的艾尔弗莱德·布洛格斯就是一个例子。

【分析】as 是连词，引导“比较状语从句”，it 是代词，指代“前文整个句子”，did是“替代词”，替代前文的“谓语动词”。 

in the case of：就......来说，就......而言；至于。

as it did in the case of，意思是：该情况对......而言也是如此。

本句翻译成“某人就是一个例子”。

又如：

This can give rise to embarrassing situations, as it did in the case of Jane who came from a DINK family.

这会引起种种尴尬的现象，来自丁克家庭的简就是一个例子。

Visits to really remote places are seldom enjoyable, as it did in the case of my wife on a tour to the Balkans where she received the cold shoulder.

到真正偏僻地方去旅游并不是一件愉快的事情，就像我妻子在一次巴尔干半岛的周游所发现的那样,在那里她受到了冷遇。
