新概念3时态 experts confirmed that a puma will not attack a human being.
原句:It immediately ran away when she see it,and experts confirmed that a puma will not attack a human being unless it is cornered.
这里confirmed (过去时) 为何它的从句为(现在时)?不是应该为(过去时)
不是应该 experts confirmed that a puma would not attack a human being
