A IS B WAS C will be D were
the methord of painting is known as __far back as the song Dynasty
A)to be used S)to have used c) to have been using d) to have been used
以上2个都选D 请问为什么

1.答案选D
以as if (as though)引导的方式状语从句或表语从句,有时用虚拟语气,若表示与现在事实相反,谓语动词用一般过去时；若表示与过去事实相反,用过去完成时；表示将来的可能性不大,用would (might,could)+动词原形.如：
He acts as if he knew me.他显得认识我似的.
They treat me as though I were a stranger.他们待我如陌生人.
He talks as if he had been abroad.他说起话来好像曾经出过国.
2.这一题也是选D,首先确定要用被动语态,所以排除B,C,这里应该用现在完成时,因为一直从宋朝延续到现在.所以答案就出来啦.
