麻烦英语高手帮我分析一下下面句子的语法 With the market prices fluctuating so much it's hard for the firm to plan a budget主要是前面with引导的复合结果从句 为什么fluctuate用的是ing 这么用表示the market prices与fluctuate是主动关系了 我觉得是被动关系 这点不能理解
原句是这样的:the market prices are fluctuating so much that it's hard… 把原因处理成with借词的状语时,看谓语fluctuate,如果它在主句中是被动就转换成"with sth fluctuated …";如果像这句一样是主动就转换成"with sth fluctuating".
