that 是必需的,
as 引导的句子中,主语是large, integrated companies large, integrated为不同范畴形容词共同修饰companies所以必须用逗号隔开。谓语have greatly downsized
, such as Bethlehem Steel, 为插入语,that 从句修饰companies,所以companies conducted operations主谓宾齐全。
如果a, once 在这儿只能为adverb,如果做conjunction, once前应该用逗号隔开。
,once
conducted operations from mining at one end of the process to shipping
at the other, (缺主语) have greatly downsized, or in some cases shut down
altogether.
肯定了once 在这儿做adverb,那么conducted operations只能修饰Bethlehem Steel,而非companies, 那第二个谓语成分如何解释,have greatly downsized,
