2014年普通高等学校招生全国统一考试(全国卷II)及答案
全国卷22014年普通高等学校招生全国统一考试第 I卷阅读题甲必考题一、现代文阅读（9分，每小题3分）阅读下面的文字，完成1～3题周代，尽管关于食品安全事件的记我不多，但我们还是看到，由于食品安全关系重大，统治者对此非常重视并作出了特别规定。
周代的食品交易是以直接收获采摘的初级农产品为主，所以对农产品的成熟度十分关注。
据《礼记》记载，周代对食品交易的规定有：“五谷不时，果实未熟，不鬻于市.”这是我国历史上最早的关于食品安全管理的记录.汉唐时期，食品交易活动非常频繁，交易品种十分丰富。
为杜绝有毒有害食品流入市场，国家在法律上作出了相应的规定。
汉朝《二年律令》规定：“诸食鳙肉，鳍肉毒杀、伤、病人者，亟尽孰燔其余•……当燔弗燔，及吏主者，皆坐辅肉赚，与盗同法。
即肉类因腐坏等因素可能导致中毒者，应尽快焚致，否则将处罚当事人及相共官员。
唐朝《唐律》规定：“脯肉有毒，曾经病人，有余者速焚之，违者杖九十。
若故与人食并出卖，令人病者，徒一年；以故致死者，绞.即人自食致死者，从过失杀人法。
”从《唐律》中可以看到，在唐代，知脯肉有毒不速焚而构成的刑事犯罪分为两种情况，处罚各不相同：一是得知脯肉有毒时，食品的所有者应当立刻焚鲠所剩有毒食品，以绝后患，否则杖九十；二是明知脯肉有毒而不立刻焚毁，致人中毒，则视情节及后果加以科罚。
宋代，饮食市场空前繁荣。
孟元老在《东京梦华录》中，追迷了北宋都城介封济的城市风貌，并且以大量笔墨写到饮食北的昌盛，书中共提到一百多家店镝以及相关行会。
商品市场的繁荣，不可避免地带来一些问题，一些商敌“以物市于人，敝恶之场，婢为新奇；假伪之物，饰为真实.如绢帛之用胶糊，米麦之增温润，肉食之灌以水，药材之易以他物（《袁氏世范》）有的不法分子甚直采用鸡塞沙，鹅羊吹气、卖盐杂以灰之类伎俩谋取利润。
为了加强对食品掺假、以次充好等现象的监督和管理，宋代规定从业者必供加入行会，而行会必须对商品质量负责，“市律谓之行者，因官府科索而得此名，不以其物小大，但合充用者，抒为行，皆置为行，虽医卜亦有职.”（《都城纪肚》，商人们依经营类行组成行会，商铺、手工北和其他服务性行业的相关人员必领加入行会组织，并按行业登记在籍，否则就不能从业经营。

And that‘s true all across the country.―I thought it would be very useful for him to learn Chinese at an early age‖ Joseph Stock, the managing director of a company, says of his 2-year old son. ―I would at least like to give him the chance to use the language in the future,‖ After only six months of being cared by 25-year-old woman from China, the boy can already understand basic Chinese daily expressions, his dad says. Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China. She didn‘t want her children to miss out ontheir roots.‖ Because I am Chinese, my husband and I wanted the children to keep exposed to(接触) the language and culture.‖ she says.―Staying with a native speaker is better for children than simply sitting in a classroom,‖ says Suzanne Flynn, a professor in language education of Children.‖ But parents must understand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or 12.‖The popularity o au pairs from china has been strengthened by the increasing numbers of American parents who want their children to learn Chinese. It is expected that American demand for au pairs will continue to rise in the next few years.9.What does that term‖ au pair‖ in the text mean?A. A mother raising her children on her ownB.

AArriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a short time while looking for a house for me and our children.During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.He reported the case to the police and then sat there ，lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband ’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can （垃圾桶）that had been left out on the footpath.My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half –written letter in the pile in which my husband had given his new telephone number to a friend.That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.姓名______________________ 准考证号__________________________________21. What did Rashid plan to do after his arrival in Sydney?A.

In Search of New Friends.BSince the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that tim e there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass–roots Americans are taking part in the movement. “The understanding has inc reased many, many times,”says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions （排放）from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking “has become part of practices.Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.Twenty–five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.25. According to Anderson, before 1970, Americans had little idea about _________.A. the social movementB. recycling techniquesC. environmental problemsD. the importance of Earth Day26. Where does the support for environmental protection mainly come from?A. The grass–roots level.B. The business circle.C. Government officials.D. University professors.27. What have Americans achieved in environmental protection?A. They have cut car emissions to the lowest.B. They have settled their environmental problems.C. They have lowered their CO levels in forty cities.D. They have reduced pollution through effective measures.28. What is especially important for environmental protection according to the last paragraph?A. Education.B. Planning.C. Green living.D. CO reduction.COne of the latest trend（趋势）in American Childcare is Chinese au pairs. Au Pair in Stamford, forexample, has got increasing numbers of request for Chinese au pairs from aero to around 4,000 since 2004. And that’s true all across the country.“I thought it would be useful for him to learn Chinese at an early age” Joseph Stocke, the managing director of a company, says of his 2–year old son. “I would at least like to give him the chance to use the language in the future,” After only six months of being cared by 25–year–old woman from China, the boy can already understand basic Chinese daily expressions, his dad says.Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China. She didn’t want her children to miss out on their roots. “Because I am Chinese, my husband and I wanted the children to keep exposed to（接触）the language and culture.” she says.“Staying with a native speaker is better for children than simply sitting in a classroom,” says Suzanne Flynn, a professor in language education of Children. “But parents must understand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or 12.”The popularity if au pairs from China have been strengthened by the increasing numbers of American parents who want their children who want their children to learn Chinese. It is expected that American demand for au pairs will continue to rise in the next few years.29. What does that term “au pair” in the text mean?A. A mother raising her children on her own.B. A child learning a foreign language at home.C. A professor in language education of children.D. A young foreign woman taking care of children.30. Li Drake has her children study Chinese because she wants them _________.A. to live in China some dayB. to speak the language at homeC. to catch up wit other childrenD. to learn about the Chinese culture31. What can we infer from the text?A. Learning Chinese is becoming popular In America.B. Educated woman do better in looking after children.C. Chinese au pairs need to improve their English Skills.D. Children can learn a foreign language well in six months.DMetro Pocket GuideMetrorail（地铁）Each passenger needs a farecard to enter and go out.

2014年普通高等学校招生全国统一考试全国II卷语文真题(含答案解析)
2014年普通高等学校招生全国统一考试课标全国卷Ⅰ语文本卷满分150分,考试时间150分钟。
第Ⅰ卷阅读题甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1—3题。
悲剧产生于社会的矛盾、两种社会力量的冲突。
冲突双方分别代表着真与假、善与恶、新与旧等对立的两极,却总是以代表真、善、新等美好的一方的失败、死亡、毁灭为结局,他们是悲剧的主人公。
因为他们的力量还比较弱小,还无法与强大的旧势力或邪恶力量抗衡,正义的要求不能实现,于是形成了悲剧。
古希腊学者亚里士多德指出,悲剧描写了比现实中更美好同时又是“与我们相似的”人物,通过他们的毁灭“引起怜悯和恐惧来使感情得到陶冶”,即产生净化的作用。
然而,悲剧不仅表现冲突与毁灭,而且表现抗争与拼搏,这是悲剧具有审美价值的最根本的原因。
鲁迅说过:“悲剧将人生的有价值的东西毁灭给人看。
”这种毁灭是抗争、拼搏以后的毁灭,抗争与拼搏体现了人的一种精神。
古希腊神话中普罗米修斯为了人类从天上盗取火种,触怒了主神宙斯,被锁在高加索山崖上,每日遭神鹰啄食肝脏,但普罗米修斯毫不屈服,最后坠入深渊。
罗丹的大理石雕塑《马身人首》中,人臂绝望地扑向一个它所抓不到的目标,而马足则陷于尘土不能自拔,表现出人性与兽性的冲突,象征着灵与肉的斗争,具有强烈的悲剧性。
可以说,没有抗争就没有悲剧,冲突、抗争与毁灭是构成悲剧的三个主要因素。
悲剧的审美价值的载体只能是文学艺术。
因为人生有价值的东西、美好事物的毁灭是令人伤悲的,因此现实中的悲剧不能作为直接的审美对象来欣赏,否则人就是泯灭了人性的人了。
现实中的悲剧只能激起人的同情、义愤,迫使人采取严肃的伦理态度和实践行动。
民主革命时期,在演出歌剧《白毛女》的过程中,曾多次出现扮演地主黄世仁的演员被打甚至险遭枪击的事件,这是人们以实际的道德评价代替了审美活动。
现实的悲剧只在客观上具有悲剧的审美性质,它们必须以文学艺术的形式表现出来,才能成为欣赏的对象,美学上所谓的“以悲为美”才能实现。

第Ⅰ卷 阅读题甲 必考题一、现代文阅读（9分，每小题3分） 阅读下面的文字，完成1～3题。
周代，尽管关于食品安全事件的记载不多，但我们还是看到，由于食品安全关系重大，统治者对此非常重视并做出了特别规定。
周代的食品交易是以直接收获采摘的初级农产品为主，所以对农产品的成熟度十分关注。
据《礼记》记载，周代对食品交易的规定有：“五谷不时，果实未熟，不鬻于市。
”这是我国历史上最早的关于食品安全管理的记录。
汉唐时期，食品交易活动非常频繁，交易品种十分丰富。
为杜绝有毒有害食品流入市场，国家在法律上作出了相应的规定。
汉朝《二年律令》规定：“诸食脯肉，脯肉毒杀、伤、病人者，亟尽孰燔其余。
……当燔弗燔，及吏主者，皆坐脯肉赃，与盗同法。
”即肉类因腐坏等因素可能导致中毒者，应尽快焚毁，否则将处罚当事人及相关官员。
唐朝《唐律》规定：“脯肉有毒，曾经病人，有余者速焚之，违者杖九十。
若故与人食并出卖，令人病者，徒一年；以故致死者，绞。
即人自食致死者，从过失杀人法。
”从《唐律》中可以看到，在唐代，知脯肉有毒不速焚而构成的刑事犯罪分为两种情况，处罚各不相同：一是得知脯肉有毒时，食品的所有者应当立刻焚毁所剩有毒食品，以绝后患，否则杖九十；二是明知脯肉有毒而不立刻焚毁，致人中毒，则视情节及后果加以科罚。

2014年高考语文全国卷2-答案
2014年普通高等学校招生全国统一考试（全国卷II）语文答案解析第Ⅰ卷阅读题甲必考题一、现代文阅读1．【答案】C【解析】“《二年律令》中的规定注重对主使官员责任的追究”错，应是对“当事人及相关官员”都进行责任追究。
2．【答案】B【解析】“设立了行会这一政府机构”错，“行会”组织不属于政府机构，是政府为加强对民间工商业者的监管而批准成立的民间组织。
3．【答案】B【解析】由原文“各个行会对生产经营的商品质量进行把关”可知，“对生产经营的商品进行质量把关”的不是宋代政府，而是相应的行会。
二、古代文诗文阅读4．【答案】D【解析】著：记录，登记。
5．【答案】C【解析】首先明确人物，也就是号称“八虎”的刘瑾等八人。
这是一个判断句，“八虎”后应断开，故排除A、B两项。
然后说的是“八虎”的一系列罪恶行为，即每天带领皇帝不务正业。
“不亲万几”是不理政务的意思。
另外，“文每退朝对僚属语及辄泣下”这句的意思是韩文每次退朝的时候，和下属说起这件事情，就会痛哭，“辄”前应断开。
采用排除法，故选C项。
6．【答案】B【解析】“着手压缩编制”于文无据。
7．【答案】（1）淳安公主受赐田地有三百顷，又想强夺任丘民众的产业，（因）韩文尽力相争才停止。
（2）随即与各位大臣一道拜伏宫阙上奏，奏章呈进，皇帝惊哭不食，刘瑾等人大为恐惧。
8．【答案】诗人是用衬托的方法来表现感情的。
诗人虽然到处漂泊，但好像对此并不在意，认为这是“等闲”之事；而客中一觉梦醒，思家乡、念亲人的惆怅之情不禁油然而生。
9．【答案】韦诗中，“灯前”表现了诗人旅途漂泊中的凄清、失神、怅惘之情；郭诗中，“灯前”表现了诗人住宿渔家所感受到的温暖、愉悦之情。
（意思对即可）10．【答案】（1）朝菌不知晦朔蟪蛄不知春秋（2）长风破浪会有时直挂云帆济沧海（3）舳舻千里旌旗蔽空乙选考题三、文学类文本阅读11．【答案】ACE【解析】B．“小说善于使用对比手法”错，守明的形象主要是通过心理描写凸显出来的。
