18.(15分)(1)1945年2月,世界反法西斯战争胜利在望;苏美英三国首脑在雅尔议会议主要参加者有斯大林、罗斯福和丘吉尔:会议协调了动,加快了战胜法西斯的步伐;对战后世界特别是欧洲做出安排。用三件放在座椅上的衣物代表着“三巨头”并小激:“V”形表示着反法西斯战争胜利在望,结局光明:窗外天空的明云酸”的隐忧。雅尔塔会议既给人们带来了胜利光明,也带有明显政治(2)略

25.【参考答案】(1)措施:设置隔离区;研究治疗疫病的药方等。(6分)意义:有助于早日战胜疫病,减轻民众疾苦:推动了中国古代中医学的发展;有利于社会稳定,国家巩固等。(6分)(2)同:都重视,制定制度法规。(4分)异:北洋政府主要依靠政府力量,但其社会控制力较弱,效果有限;(3分)新中国依靠党的,充分发挥人民的力量,效果明显。北洋政府时期,应对水平有限制,缺乏社会互动;(3分)新中国的措施更加全面,有预防注射、报告制度。(3分)

(二)选考题1日普)(1)①44p(2分)②BCE(1分)③>(1分)二者均为共价品体,P原子半径小于As,P-Ga键键长小于As-Ga键P-Ga键键能更大,GaP熔点更高(2分)(2)共价键(1分)能(1分)(3}16(2分)Cu2O中Cu的3d轨道处于全满的稳定状态,而CuO中Cu2的3d轨道排布为3d°,能量高,不稳定(2分)(3分)3/3xa'cN命题意圈本题综合考查物质结构与性质,涉及电子排布、化学键、晶胞的分祈与计算等,考查学生从微观角度分析物质可能的性质与反应特征的能力,综合考查学生对物结构与性质的认识与掌握程度。审壓指导熟悉“位一构—性”之间的关系;掌握晶胞“均滩法”的应用、化学键对物质性质的影响等。解题思路(1)②磷化镓晶胞结构与金刚石类似,化镓品体为共价品体,只存在共价键。晶胞中每个P原子与4个Ga原子以单键相连,每个Ga也与4个P以单键相连,而P原子最外层有5个电子,Ga原子最外层有3个电子,所以4个化学键中有1个配位键其余单锉是极性共价键,是σ键,故选B、C、E。③磷化镓和砷化镓均为共价晶体,砷原子的半径大于磷原子,故P-Ga键键长小于As-Ca键,P-Ga键键能大,磷化镓熔点高。(2)由题中数据可知Be和Cl的电负性差值为316-157=1.59,小于1.7,则BeCl2中的化学键为共价键;根据“相似相溶”规律,推断BeCl2固体能溶于CCl4。(3)Cu2O晶胞中含有的O原子的个数为4+6x+8x8则Cu原子的个数为8×2=16。(4)由题维品胞图可知,1个晶胞中含有的Fe原子的个数为3+2×-+12x=6,N原子的个数为,晶胞体积为3·aCt·Ccmcm3,则晶体密度为256×6+14×2728cmcm oa C3√3×a2cNxN解后反思晶体的密度计算方法、化学键特征与性质的关系等需认真掌握。

写作Paragraph lAnd not very long after that, he made a surprising decision. Hedecided to use all hghts to prepare for his li fe at the remoteisland. In the first year he sent troops, veterinarians and animalrainers to kill the wild animals or train them for good use. Thetask was so huge but it was wor thwhile then the king sent a lot offarmers to start a wide rice field and began to grow rice. Next head many facilities, from hospi tal to school, built.【高分句型一】After that he sent a lot of educated people there. At last he sentall his families to the island.(岛屿的建设和发展)Paragraph 2Finally the time came when the king had to be thrown away to thesland.【高分句型二】 Wi th many strong soldiers catching him,hesmiled. He had prepared every thing for the final day.When he was sent to the island, the is land had taken on a new lookEverybody there lived a comfortable life and the king was welcomedwarmly by his people. They cheered, long live the wise kingThe wise king lived happily ever after. The clever people live nown the world to prepare for their life in the future.(国王最终在自己的岛屿上生活)
