Without your help ,we ___so much A.won't achieve B.didn't achieve C.don't achieve D.wouldn't have achieved 选D为什么?

这样就很明显地看出主句必须用would + have +过去分词

without引导的条件状语重句,主句要用虚拟语气

这是对过去的假设,意为如果没有。。。。会怎么样。用虚拟语气表示

对过去虚拟

Without your help替换了一个虚拟的条件句:If we hadn't got your help或者If you hadn't helped us

Be have done
