12. Rising inventories, whenunaccompanied correspondingly by increases in sales, can lead to

productioncutbacks that would hamper economic growth.

(A) when unaccompanied correspondingly by increasesin sales, can lead

(B) when not accompanied by corresponding increasesin sales, possibly leads

(C) when they were unaccompanied by correspondingsales increases, can lead

(D) if not accompanied by correspondingly increasedsales, possibly leads

(E) if not accompanied by corresponding increases in sales, can lead

E中，If 引导的不是应该是个从句吗。。。。但是这个怎么没有谓语那

谢啦  说的很好 还有个小疑问、、为什么不是IF are Not accompanied by corresponding increases in sales. 根据逻辑，这里应该是 rising inventories 是这句话的主语啊？

supervivian

。。。。。你的意思是 因为这个主句和从句的时态相同，所以它这个BE给省略掉了？

状语从句的省略

摘自prep08语法笔记：


状语从句的省略：
1） 两点省略要求：
第一点是毫无疑问的：逻辑主语等于句子主语
第二点也是必须的：从句的谓语必需是be（没要求主句谓语也必需是be！换句话说状从的省略可以看成是省略了一个be），且从句主语和谓语要么同省，要么同留。
2）形式
(5) 正确形式: 表示时间/条件/转折/让步的连词(when/while/if/unless/although/even though/even if) + 形容词短语/-ing短语/-ed短语
(逻辑主语等于句子主语)  (所以when a child/ when children是错的； if + n.也是错的)
(6) 错误形式:表示时间/条件/转折的连词 + 介词短语/名词短语 (although just inside the orbit of Jupiter是错的)(OG10-69)
(7) 特殊情况nce可以加介词短语/名词短语; whatever可以加名词短语
