The steel industry has changed radically over the last two decades, as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one end of the process to shipping at the other have greatly downsized, or in some cases shut down altogether.

Aas large, integrated companies such as Bethlehem Steel
Bas large, integrated companies, such as Bethlehem Steel, that
Cwith large, integrated companies, such as Bethlehem Steel, that
Dwhile large, integrated companies, such as Bethlehem Steel, that
Eand large, integrated companies such as Bethlehem Steel

正确答案 B

求解as在这里做什么解释，D中的while为什么不能用？是因为while表示主句从句动作同时进行，这里不合适，还是别的原因，求解，谢谢了。

+1，while做然而不行吗在这里？
我感觉有时候分不清while是同时的意思还是然而的意思，怎么区分呢？有时候翻译中文的时候感觉2个都说得通，然后就不小心选择了他。

顶！说的很好。 as连接句子表动作比较，这里是changed radically以及 have downsized的动作比较。 as还可以加名词表作为，或者连接句子做原因状语从句
