        材料二南宋至晩清,绝大多数史学家认为王安石变法“祸国殃民”,是北宋亡国的元凶范仲淹等人修订的《神宗实录》、南宋孝宗李焘等人修撰的《四朝国史》、元朝史臣编修的《宋史》均认为王安石变乱祖宗法度,祸国殃民,把王安石的诸项新法称作聚敛之术,认为王安石的理财思想“弱民兴利”。近代以来,梁启超为王安石变法翻案,称“若乃于三代以下求完人,唯公(王安石)庶足以当之矣”。在当代中国,对王安石变法的评价日益客观和公正

18.(1)证明:因为底面ABCD是菱形,所以AC⊥BD1分因为AC⊥PB,且BD∩PB=B,所以AC⊥平面PBD.………2分因为PD二平而PBD.所以AC⊥PD分因为AB-AD.且∠BAD-60°,所以BD-AB,1分因为PB=√AB=√2PD,所以PD÷BD=PB,则PD⊥BD.………5分因为AC与BD相交,所以PD⊥平而ABCD.………………………………6分(2)解:记AC∩BD=O以O为坐标原点射线OAOB分别为x,y轴正半轴过点O的乖线为z轴,建立如图所示的空间直角坐标系Oryz设AB-2则B(0,1,0),C(-3,0.0),P(0.-1.2).从而BC-(-3,-1.0),BF-(0.-2.2)7分设半面PBC的法向量n-(x,y,),/30一令x=1.得n=(1.-3,-3).……………8分易知平面PBD的一个法向量m=(1.0.0)………………………9分cos(n,n)=-.nIMv7……………11分设二面角D-PB-C为0,由图可知为锐角,则c0s=cos(nm)=分,
