( )in the mine for 3 days ,the miners were rescued successfully at last
A,Trapped B,Trapping
C,Having trapped D,Having been trapped .
选D.第一,要名词,A排除.
分析句子时态,后半句是过去时,所以前半句不可能是B.
选D是因为这是被动态.被关在矿井里三天.(可参考后半句 were rescued)
再问: D是被动态?不是现在完成时时态吗?C为什么不对啊
再答: CD都是现在完成时啊(have done),不过D是被动(be done),更符合原意:被关在矿井里三天。所以D现在完成+被动就变成了 have been done
