"but that prediction would not have adversely affected the dollar had it not been for the government's huge budge deficit"句中dollar后面的话怎么读，句子结构是什么？ 先谢过了！                                                                                                                                                                   -----摘自 陈向东 《gre gmat lsat 逻辑推理》

had it not been for the government's huge budge deficit = if it had not been for the government's huge budge deficit 是虚拟语态

but that prediction would not have adversely affected the dollar had it not been for the government's huge budge deficit
个人觉得，dollar后边省略了一个that，后边用倒桩修饰dollar，不过你这整句是什么呢？

请贴整句，谢谢

虚拟语气，had后语序应为 if it had not been for the government's huge budge deficit.

虚拟语气。啊，两个否定，换成正的：）

3# cunshang 同谢谢，整句是“but that prediction would not have adversely affected the dollar had it not been for the government's huge budge deficit, which must therefore be decreased to prevent future currency declines.”
