∠B=∠MDN=60°：作DH⊥BC于H在等边三角形中解，DM=DN∵∠B+∠BMD=∠MDN+∠ADN(三角形的一个外角等于不相邻两个内角之和）∴∠BMD=∠ADN∵∠DAN=∠DHM=90°∴⊿DAN≌⊿MHD∴AN=HD∵D是AB中点，AB=8∴BD=4∴BH=1/-BH&#178;2BD=2
DH=√(BD&#178

则FN=AN&#47,∠DAN=90,因此∠ADM=90°,所以OB=2BC又因为D为AB中点即AB=2BD，∠BAO=90°,得出DM平行于AC，又因为AD=4,且△ABC为等边三角形，则∠ADN=30°，因此∠AOB=30°，则∠AFN=90°;3，则OB=2AB，则∠CAO=30°，∠ACD=60°,又因为AB=BC.因为DM平行于AC延长AN;3，因此AN=4x根号3/2=2x根号3&#47。∠DAN=90，BC相交于O

帮忙做一下下面这个诗歌鉴赏.夜泊宁陵韩驹 汴水日驰三百里,扁舟东下更开帆.旦辞杞国风微北,夜泊宁陵月正南.老树挟霜鸣窣窣,寒花垂露落毶毶.茫然不悟身何处,水色天光共蔚蓝.（1）请简
帮忙做一下下面这个诗歌鉴赏.夜泊宁陵韩驹 汴水日驰三百里,扁舟东下更开帆.旦辞杞国风微北,夜泊宁陵月正南.老树挟霜鸣窣窣,寒花垂露落毶毶.茫然不悟身何处,水色天光共蔚蓝.（1）请简要分析颈联中“挟”和“垂”的妙处.（2）诗人的情感发生了怎样的变化?请简要分析.
老树挟霜,挟字运用拟人手法,生动形象地描绘出深秋萧瑟的景象,严霜覆盖在树枝上,倒像是被枯树挟着,言简意赅,别有一番妙处.寒花垂露,一个垂字,写尽了雾浓霜冷,有露水沾衣,江中冷清,不必多言语的严寒冷漠.鲜花露珠本是人间一美景,奈何花寒落毶毶.从此二字可以看出,作者剪切锤炼之功寓于流动朗畅气格之中,通体贯串,语气顺畅,情感自字里行间游走.【韩驹善用典故,抱歉我对这首诗不熟,如果课本上有注释,可按注释结合着回答,他的诗一般字字有出处,俗话说就是掉书袋o(∩_∩)o 】2
诗歌颈联用老树寒花等意象,描绘出环境萧瑟、气氛森严的意境；尾联则从眼前水天之景,转出茫然身世之情,境界变得深沉寥廓.饱含了诗人身遭党祸,茫然不知所适的心情.}
