下列判断错误的是（　　）

A．命题“若q则p”与命题“若非p则非q”互为逆否命题

B．“am2＜bm2”是“a＜b”的充要条件

C．对于命题p：∃x∈R，，使得x2+x+1＜0，则∧p为∀x∈R，均有x2+x+1≥0

D．命题“∅⊂{1，2}或4∉{1，2}”为真命题

答案

据逆否命题的定义是：条件、结论同时否定并交换，故A对；

当m=0时，由a＜b推不出am2＜bm2，故B错；

据含量词的命题的否定形式：将“∃”与“∀”互换，且结论否定，故C对；

由于“∅⊂{1，2}”是真命题，“4∉{1，2}”也是真命题，所以“∅⊂{1，2}”或“4∉{1，2}”为真命题，故D对

故选B．

云锦，世博会上的南京名片

       ①南京云锦，被誉为中国古代织锦工艺史上一座里程碑。这一由历史沉淀出的华美织物，在上海世博会上成为一道亮丽的风景。 

       ②南京云锦雍容华美，内涵丰富。它用材考究，极为奢华，大量使用金线、银丝、孔雀羽等昂贵材料，生产出来的面料可谓“寸锦寸金”。在封建社会曾成为御用贡品。从色彩上看，整个织物金碧辉煌，流光溢彩。相传玉皇大帝为装饰天宫，命织女们日夜织锦，朝为锦云，暮为绮霞。当人们仰望那满天的霞光异彩时，无不为织女们的心灵手巧而赞叹不已。传说归传说，但南京云锦确如彩云般绚烂多姿，瑰丽华美。从图案上看，形象各异，寓意鲜明。它吸收了我国古代传统图案精华，既有象征高洁的莲花，也有寓意多子的石榴；既有龙凤麒麟这等祥禽瑞兽，也有喜鹊鹦鹉之类喜庆小品；既有祈盼长寿的仙翁寿叟，也有活泼可爱的顽童婴孩……无怪乎明末文人吴梅村赞曰：“江南好，机杼夺天工，孔雀妆花云锦烂，冰蚕吐凤雾绡空，新样小团龙。”

       ③南京云锦工艺高超，巧夺天工，集历代织锦工艺之大成。其织造非常独特，须在5.6米长、4米高、1.4米宽的木质提花机上，由上下两人配合操作方能生产。从设计图稿到完成织物，整个过程如同电脑运算一般精确而复杂。“挑花结本”、“通经继纬”等独特织锦工艺，至今尚不能为现代机器所替代。正在世博会上展出的《九龙图》，更藏玄机。如果变换角度和光线，正中的那条墨绿祥龙便能显现紫、蓝、绿、棕、黑等不同色彩，金翠交辉，奇丽夺目，其精妙的制作工艺唯南京云锦独有。 

       ④当然，南京云锦的织造也特别耗时费力。据介绍，两名熟练织工在木织机上配合无间地工作，一天最多也只能织成不满两寸的云锦。诗云：“丝细缲多女手疼，扎扎千声不盈尺。”这是说织造缭绫的；如果用来形容云锦，则要“扎扎千声不盈寸”了。要是织造大型艺术云锦，耗费的心力更是无法估计。就连六巡江南的康熙皇帝，幸临曹雪芹祖上任职的江宁织造府时，也在诗中感叹“终岁勤劳匹练成”。

        ⑤南京云锦在继承中创新。以世博吉祥物“海宝”为主题的南京云锦装饰画上，设计师以深浅不一的蓝色，勾勒出8个生动活泼的“海宝”形象。每个海宝的色彩造型各异，甚至连勾边的蓝色都有细微区别，让见惯了传统型云锦的人们眼前为之一亮。还有一幅不到一平方尺的云锦，上面惟妙惟肖地织出一座牡丹花掩映的世博中国馆“东方之冠”。其花色的变化，斗拱结构的光影明暗对比，无不精细入微，配合左上角的世博会会标及主题词，颇具收藏价值。这幅小型云锦装饰画，在牡丹这一雍容华贵的传统形象中，巧妙地融入“上海世博会”的现代元素，为南京云锦的传统工艺焕发青春活力提供了借鉴。

       ⑥“城市，让生活更美好。”在世博会上尽显风采的南京云锦，不正是南京通向更加美好未来的一张城市名片吗？

1．阅读第②节，说说南京云锦的“雍容华美，内涵丰富”表现在哪些方面。

                                                                                                                                                              

2．第③节介绍《九龙图》有什么作用？

                                                                                                                                                             

3．第④节画线句中画线的“最多”一词能否删去？为什么？

     一天最多也只能织成不满两寸的云锦。

                                                                                                                                                             

4．下列对文章理解和分析有误的一项是[ ]

      A．第②节插入天女织锦的传说，表现了云锦的瑰丽华美，增强了阅读趣味。

      B．第④节引用“扎扎千声不盈尺”，意在形象地说明云锦织造的精细考究。

      C．由历史沉淀出的南京云锦，如今已经成为上海世博会上的南京名片。

      D．文章按“总一分一总”的思路介绍南京云锦，条理清晰，结构严谨。

5．根据文章内容，你认为怎样才能让南京云锦“焕发青春活力”？
