2016年全国3卷高考语文真题及答案解析

2016年普通高等学校全国统一招生考试新课标Ⅲ卷 语文试题 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。 文学中有历史。当今历史学家大都认为,没有什么文献资料不是史料,不但文学作品,即如佛经、道藏、信札、家谱、账本、碑铭等也无一不是,而且随着史学研究领域的拓展,史料范围还在不断扩大。从“三言二拍”里可以看到晚明市井生活的真实面貌,这对于研究社会史的人几乎是一个常识。陈寅恪以诗证史,也为大家所熟悉。但在“五四”以前,史料范围并非如此宽泛,文学作品在大多数史学家眼里也并非史料,有些文献到底属于文学还是史学,一两千年来都没有一致的看法。神话传说就是如此,其中相当突出的例子是《山海经》。 神话传说是文学,史前时代,无文字可征,只有传说,暂当历史。三皇五帝至今未曾坐实,但“炎皇子孙”已经成为口头语,甚至成为历史共识。新的传说还会不断产生,能否成史颇为可疑,但以神话传说研究历史,却是一种重要的方法。在历史上,《山海经》究竟应归于文学还是史学,曾是死结。王国维《古史新证》说“而疑古之过,乃并尧、舜、禹之人物而变疑之,其于怀疑之态度及批评之精神不无可取,然惜于在于史材料未尝为充分之处理也。”这些古史材料就包括《山海经》《穆天子传》等文献。在《汉书·艺文志》里,《山海经》列于数术类。此后该书在目录学里的角色转换过几次,《隋书·经籍志》将《山海经》列于史部地理类,也就是将它看成史书了。 历史是讲真实的,《山海经》一般被视为荒诞不经,连司马迁写《史记》都不敢采用。虽然《山海经》里平实的山川地理内容应归于史部,但其中大量的神话故事却显然有悖信史,所以清人编《四库全书》,言其“侈谈神怪,百无一真,是直小说之祖耳”,将其改列于子部小说家类。这个死结直到“五四”以后才大致解开。解开的途径有二:一是将《山海经》分而治之,不把它看作一部成于一人一时之书,神话归神话,历史归历史;二是神话中也有历史的成分在,仍可以之证史或补史。分而治之者,以为《山海经》中的《五藏山经》是比较雅正的部分,谭其骧就写了《<五藏山经>的地域范围》一文,分析《山经》写作时的地理知识水平。将历史成分发掘出来的,自然以王国维用《山海经》来印证甲骨文中殷商先王亥为最明显的例子。 上面说的是介于文学与史学之间的文献,至于纯粹的文艺作品,当然也能从中发掘史料。但发掘史料是一回事,把整个作品当成真史就很可虑了。《红楼梦》反映了清代前期的历史现实没有错,可是如果过分坐实到具体历史人物身上,就未免失之穿凿了。戏说之类当然是文学,但读者观众往往误以为是历史。如中俄签订《尼布楚条约》,张诚、徐日昇当时担任与俄国谈判的翻译,工作是以拉丁语作为中介的,而电视剧《康熙王朝》中他们说的却是俄语,观众看到这个情节时被误导也就难以避免了。 (摘编自周振鹤《历史中的文学与文学中的历史》) 1.下列关于原文内容的表述,不正确的一项是( ) A.在当今历史学界,历史学家的研究领域不断地扩展,各种体裁的文学作品都有可能成为他们研究历史的资料。 B.古代的史学家选取史料的范围比较狭窄,他们并未广泛采用“以诗证史”或将小说用于社会历史研究之类的方法。 C.王国维在《古今新证》中认为,有些历史学家如果能充分利用史料,就不会“疑古”,怀疑尧、舜、禹等人物的真实性。 D.历史学者对《山海经》有不同认知,《隋书·经籍志》把它列入史部,视为史书,王国维则把它作为古史材料看待。 2.下列理解和分析,不符合原文意思的一项是( ) A.很多人认为《山海经》的记载荒唐夸张,与真实的历史差别较大,司马迁也持这种观点,因此《史记》并不采用《山海经》。

2016年高考英语全国Ⅰ卷试题及答案

2016普通高等学校招生全国统一考试(新课标I) 英语试卷类型A 第Ⅰ卷 第二节(共 5 小题,每小题 2 分,满分10 分) 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。 Secret codes (密码)keep messages private。Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer. People have used secret codes for thousands of years. 36 Code breaking never lags(落后) far behind code making. The science of creating and reading coded messages is called cryptography. There are three main types of cryptography. 37 For example, the first letters of “My elephant eats too many eels” Spell out the hidden message “Meet me.” 38 You might represent each letter with a number, for example. Let’s number the letters of the alphabet, in order, from 1 to 26. If we substitut e a number for each letter, the message “Meet me” would read “13 5 5 20 13 5.” A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 39 For example, “bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me.”40 However, it is also hard to keep a code book secret for long. So codes must be changed frequently. A. It is very hard to break a code without the code book. B. In any language, some letters are used more than others. C. Only people who know the keyword can read the message. D. As long as there have been codes, people have tried to break them. E. You can hide a message by having the first letters of each word spell it out. F. With a code book, you might write down words that would stand for other words. G. Another way to hide a message is to use symbols to stand for specific letters of the alphabet. 第三部分英语知识运用(共两节,满分45分) 第一节完形填空(共20小题;每小题1.5分,满分30分) 阅读下面短文,从短文后各题所给的四个选项(A、B、C 和D)中选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑。 A Heroic Driver Larry works with Transport Drivers, Inc.
