河南省普通高中2015届高考模拟高三高考适应性模拟练习试题高考模拟试卷0522 21:36::河南省普通高中2015届高考模拟高三高考适应性模拟练习试题语文第Ⅰ卷阅读题必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题。

译者对外文驾轻就熟,这是从事翻译工作最起码的一项资质。

这项资质看似明了,其实大家对其有莫大误解。

有人以为现在大学生都学外文,尤其是外语系的毕业生拥有专业文凭,翻译起来肯定不成问题——其实大不然。

要知道,我们所说的翻译是笔译,它与讲外语和口译不是一回事,差异相当大。

因为口语表达往往句式单纯,通畅易懂,而且可以回避一些难点。

笔译不同,面对的是错综复杂的句型,还有难解的文字。

特别是有些原著,概念抽象,内容艰深,又善于笔走龙蛇,或喜好舞文弄墨,这种文字更是不好对付。

译者没有高超的外文水准,没有多年的翻译经验,是无法啃动这样的硬骨头的。

无论是术语、概念的定名,还是句子的组织和译文的表达,都要用准确、晓畅、优美的中文传达给读者。

即使译者外文不错,如果没有深厚的中文功底,难免译名不确,语句不顺,意思不明,更无法使读者在了解原意和思想的同时,得到美的愉悦和享受。

比如,《Symposium》是柏拉图论述爱情与美的著作。

symposium足古希腊宴会后的演讲、交际酒会,是一种具有庆祝意味的礼节和仪式。

译者将《Symposium》翻译为《会饮篇》,其灵感显然来自古人的名句:“酒逢知己饮,诗向会人吟。

”没有足够的古典文学知识,怎能选择如此富有诗意的译名?即使是简单的译名“幽浮”(UFO),译者没有一定的中文修养,岂能译得如此谐音又传神?至于堪称美文的译文,多半是译者中文功力酣畅淋漓的挥洒。

译者还要具备专业知识。

这一点十分重要,但是并没有引起人们的足够重视。

对于一般常识性的原著,有一定的文化知识大体就可以应对。

但是,要翻译学科性强的原著,没有必要的专业知识则是万万不行的。

否则,一不留神就闹出把“科学共同体”(scientific community)译成“科学社区”的外行话,把“能”(energy)译为“精力”的大笑话。

(9分)按照中国文化的理解,道作为宇宙人生的终极原理和统一的真理,无法与人相分。

《老子》已提出“城中有四大”之说,所谓“四大”则指道、天、地、人四项,其中既包括广义的“物”(天地),亦涉及人,而涵盖二者的最高原理则是道。

值得注意的是,在这里,作为最高原理的“道”与人并非彼此相分,二者作为“城中四大”中的两项而呈现内在关联。

在儒家那里,也可以看到类似观念,儒家反复强调道非超然于人:“道不远人,人之为道而远人,不可以为道也。

”道并不是与人隔绝的存在,离开了人的为道过程,道只是抽象思辨的对象,难以呈现其真切实在性。

而所谓为道(追寻道),则具体展开于日常生活过程之中。

强调“道”和“人”之间不可分割、相互联系的重要含义之一,是肯定道所具有的各种意义唯有通过人自身的知和行、认识世界和改变世界的过程,才能呈现出来。

正如深山中的花自开自落,并无美或不美的问题,只有在人的审美活动中,它的审美意义才得到呈现。

作为社会理想和规范系统的“道”,其意义更是直接地通过人自身的知行活动而形成。

上述意义上的道,都具有“不远人”的品格。

从哲学的视域看,以上观念的重要之点,在于把人对世界的理解过程和意义的生成过程联系起来。

道和人之间相互关联的另一重含义,是“日用即道”。

所谓“日用即道”,亦即强调道并不是离开人的日用常行而存在,它就体现并内在于人的日常生活之中。

这一观点的重要之点在于没有把道视为一种彼岸世界的存在或超越的对象,而是把它引入到现实之中,使之与人的日用常行息息相关;道不远人,同时也规定了道和人的实践活动无法相分。

在实践过程中道的品格具体地表现为“中”。

儒家一再谈到“中道”或“中庸之道”,孟子主张“中道而立”,荀子也肯定:“道之所善,中则可从。

2015年普通学校招生全国统一考试•模拟卷语文(教师用卷)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。

埃博拉病毒的传播途径埃博拉(Ebola virus)又译作伊波拉病毒。

是一种十分罕见的病毒,1976年在苏丹南部和刚果(金)(旧称扎伊尔)的埃博拉河地区发现它的存在后,引起医学界的广泛关注和重视,“埃博拉”由此而得名。

它是一种能引起人类和灵长类动物产生埃博拉出血热的烈性传染病病毒,有很高的死亡率,在50%至90%之间,致死原因主要为中风、心肌梗塞、低血容量休克或多发性器官衰竭。

各种非人类灵长类动物普遍易感,经肠道、非胃肠道或鼻内途径均可造成感染,感染后2~5天出现高热,6~9天死亡。

发病后1~4天直至死亡,血液都含有病毒。

豚鼠、仓鼠、乳鼠较为敏感,腹腔、静脉、皮内或鼻内途径接种均可引起感染。

成年小鼠和鸡胚不敏感。

人群普遍易感,无论其年龄和性别。

高危人群包括埃博拉出血热病人、感染动物密切接触的人员如医务人员、检验人员、在埃博拉流行现场的工作人员等。

专家们在研究中发现,“埃博拉”病毒有一定的耐热性,但在60摄氏度的条件下60分钟将被杀死。

病毒主要存在于病人的体液、血液中,因此对病人使用过的注射器、针头、各种穿刺针、插管等,均应彻底消毒,最可靠的是使用高压蒸气消毒。

埃博拉病毒还可能经过空气传播。

实验人员将恒河猴的头部露出笼外,让其吸入直径1微米左右含病毒的气雾,猴子4~5天后发病。

每天与病猴密切接触的6个工作人员的血清发现该病毒抗体阳性,其中5人没有受过外伤,也无注射史,因此认为可通过飞沫传播。

病毒可透过与患者体液直接接触,或与患者皮肤、黏膜等接触而传染。

病毒潜伏期可达2至21天,但通常只有5至10天。

虽然猴子间的空气传染在实验室中已被证实,但并不能证明人与人之间能够透过空气传播病毒。

美茵嘉护士是空气传染的可能病例,研究人员并不确定她是如何接触到病毒。

埃博拉病毒的流行大都是因为医院的环境,糟糕的公共卫生、随处弃置的针头、缺乏负压病房都对医护人员造成极大威胁。

If people vote “yes”in September,then Scotland will become an independent country. There will be no going back.As Ive made clear,this is a decision that is squarely and solely for those in Scotland to make. I believe passionately that it is in their interests to stay in the United Kingdom. But myargument today is that while only 4 million people can vote in this referendum,all 63 million of us are profoundly affected. There are 63 million of us who can wake up on September 19 in a different country with a different future ahead of them. We would be deeply weakened without Scotland,this matters to all of our futures. And everyone in UK can have a voice in this debate.The outcome is still up in the air,and we have just 7 months to go,7 months to do all we can to keep our United Kingdom as one,7 months to save the most extraordinary country in history. And we must do whatever it takes,so to everyone,in England,Wales and Northern Ireland,everyone like me who cares about the United Kingdom.I want to say this,you dont have a vote,but you do havea voice. Those voting,theyre our friends,theyre our neighbors,theyre our family,you do have an influence. So get on the phone,get together,email,tweet,speak,let me message ring out. From Manchester to Motherwell,from Pembrokeshire to Perth,from Belfast to Bute,from us to the people of Scotland,let the message be this:we want you to stay!Think of what weve done together,what we can do together,what we stand for together. Team GB,the winningteam in the history of the world,let us stick together,for a winning future too. 36.

There will be no going backBNew iPhones run into software,bending complaintsSAN FRANCISCO―Apples newest iPhones ran into some trouble Wednesday after users complained that a new software update blocked their calls,while a widespread video showed the larger of the two new models is vulnerable to bending.Apple said it would stop providing the software update,which it began distributing Wednesday morning to fix several issues in last weeks iOS 8 operating system for iPhones and iPads.The decision to pull the update came after some people complained on Twitter and in Apple user chatrooms that the update,called iOS 8.0.1,caused their phones unable to make calls and caused problems with a feature that lets people unlock their phones with their fingerprint.By midday Wednesday,Apple announced that it was investigating the reports and would issue advice to users “as quickly as we can.”Users are still able to the upgrade older phones to last weeks version of iOS 8,which Apple said has already been downloaded to nearly half of all iOS devices.Meanwhile,social media sites were buzzing Wednesday with reports that the aluminum shell of the iPhone 6 Plus is vulnerable to bending. Some Twitter users claimed their phonesshowed a slight curving at one end after several hours in a pants pocket. With a 5.5inch screen,the iPhone 6 Plus is slightly longer and thinner than other iPhone models.Its not clear how widespread the complaints are. One YouTube video showed someone bending an iPhone 6 Plus by applying extended pressure with his hands―not from normal sitting. Both the iPhone 6 and the 6 Plus were given high ratings in a recent “breakability”test conducted by SquareTrade,a San Francisco firm that sells insurance to consumers for their electronic devices. The test did not include bending.But SquareTrade Chief Marketing Officer Ty Shay said that after reports of bending circulated online,two staffers at his firm tried to bend a pair of 6 Plus phones:One staffer,a man,was able to copy the results from the video,while the other,a woman,could not. He said the bent phone appeared to still function normally.He suggested the bending is not a major issue. Referring to the iPhone 6 Plus,he added,“I think its still a very durable phone. But well keep an eye on the claims.”Apple did not comment on the reports of bending.39. According to the passage,which of the followingstatement is right?A. The version of iOS 8 was provided by Apple two weeks earlier than the version of iOS 8.0.1B. The version of iOS 8 cant be used to upgrade now because it has several serious problemsremaining to be solved.C. Being unable to make calls is the only problem caused by the iOS 8.0. 1.D. Apple will stop providing the software update to investigate the complaints.40. The reasons why the iPhone 6 Plus is vulnerable to bending maybe are all the following EXCEPT .A. Some extended pressure is applied to the iPhone 6 Plus by its user.B. The iPhone 6 Plus is slightly longer and thinner.C. The shell of the iPhone 6 Plus is aluminum.D. They didnt give the iPhone 6 Plus “bending”test.41. What can we infer from the passage?A. Apple did not comment on the complaints about the new software update.B. Apple did not make any comment on the reports of bending.C. When SquareTrade sells insurance to consumers for their electronic devices,they didnt take “bending”into consideration.D. According to SquareTrade Chief Marketing Officer Ty Shay,because the bent phone appeared to still function normally,they would pay no attention to the claims.CThe Peoples Liberation Army has geared up its fight against corruption and abuse of power,requesting that officers hand in any houses or cars they are using in violation of regulation.A leading group responsible has recently exposed a host of irregular occupancies or use of PLAowned houses and vehicles by officers,PLA Daily reported on Wednesday,citing an instruction issued by the group. The exposure of the irregularities was intended for military personnel rather than the public,with the aim of warning officers that the antigraft campaign would not stop until all corruption was rooted out,an insider close to the matter said.The PLA started a campaign in May targeting overuse of houses,cars and personnel,with the focus on violation of housing regulations,a problem that has long haunted themilitary and resulted in a great number of complaints from lowranking officers.Generally,PLA officers are provided a house after being promoted to a commander or equivalent post. The house must be returned to the unit if the occupant retires from the military,changes service units or dies. However,a considerable proportion of young,qualified officers have to wait a long time for such housing because many occupants refuse to hand over their apartments even after retiring from the PLA.Although the campaign is addressing the problem,it is still far from fulfilling the high expectations of the top leaders and grassroots servicemen,the instruction said,urging that more attention to be paid to the effort.Those who are found hiding extra housing or official cars,or who decline to return them before the given time,must be seriously disciplined,it said.In addition,the group ordered that leaders of each PLA unit should make public their housing status,the use of official cars and family members jobs.According to earlier reports,the PLA will organize an overall check to monitor the progress of the campaign in October.“As far as I know,the house and car vacating campaign will last a long period rather than the previous ones that were often shortlived,”said an officer with the PLA ground force who refused to be identified.42. Why were a host of irregularities exposed according to an insider close to the matter?A. They were exposed to give a warning to the public that the antigraft campaign would not stop until all corruption was rooted out.B. They were exposed aiming to warn the officers that the antigraft campaign would not stop forever.C. The exposure of the irregularities was intended both for the public and military officers.D. They were exposed with the intention of warning officers who decline to return houses and cars in violation of regulations.43. What can we learn from the passage?A. Occupants can continue to use their apartments even after retiring from the PLA or even die.B. All officers can live in apartments as soon as they are promoted to a commander or equivalent post.C. Violation of housing regulations is such a seriousproblem that it resulted in a great number of complaints from lowranking officers.D. A lot of young,qualified officers have to wait a long time for such housing,so many occupants are willing to hand over their apartments after retiring from the PLA.44. What does the underlined word “disciplined”probably mean?A. Punished.B. Injured.C. Fined.D. Praised.45. Whats the main idea of this passage?A. The PLA will organize an overall check to monitor the progress of the campaign in October.B. The fight against corruption and abuse of power is being carried out by the PLA.C. The antigraft campaign would not stop until all corruption was rooted out.D. Although the campaign is addressing the problem,more attention should be paid to the effort.DIt was a Sunday and the heavy storm had lasted all night. The morning after the storm,though,was beautiful:blue skies,warm air and a calm,inviting sea touching the shoregently.My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing,but I decided to go all the same. Im so glad I did.On the road to the harbor we could see the terrible destruction on the coast,but the harbor itself was in fairly good shape. After all,it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board,we noticed two big humps in the distance.On approaching them,we saw it was a mother whale with her baby. A. We couldnt believe it―there arent any whales along the coast here. The storm must have driven them across the ocean into the bay,in which the still water was so badly polluted that nothing could survive.B. The mother dived under the water and came up suddenly,making big whirlpools and waves. “Shes trying to help her baby,but on the wrong side,”my father said.C. At this point,my father moved our boat in a semicircle to the other side and,heading the boat towards the baby whale,pushed it gently.D. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up rightbeside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly,they let us lead them,sometimes rising from the water right beside us to breathe―and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea,the mum gave us a wave with her tail and off they swam into the distance. In the excitement it had felt like only a few minutes,but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day. Nearly four decades later,I still look back fondly to that golden day at sea.46.

What is the theme of the story?A. Saving lives brings people a sense of happiness.B. Fishing provides excitement for children.C. Its necessary to live in harmony with animals.D.

In blank C.D. In blank D.四、任务型阅读(共10小题,每小题1分,满分10分)请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
