阅读下面的文字,完成下列小题。
敦煌,黎明中升起
许实
清晨,第一缕曙光照在敦煌市中心的雕像上,新鲜而明媚。这是敦煌的飞天女,衣袂飘逸,花朵一样的笑容,她刚刚从夜里走来,反弹琵琶的声音,使漆黑的夜里翻腾咆哮的沙漠,此刻像天空一样宁静。
沿着绿色铺开的道路,我穿过敦煌街道。夜雨早停了,屋檐上,灌木上,电线上,树上湿漉漉的,麻雀叫着,抖掉身上黑夜,蹲在树上观察日出前每一个细节。此时,我也像麻雀抖掉黑夜,游荡在敦煌大街上。一辆辆早起的出租车穿梭在大街上,偶尔刺耳的喇叭声,唤醒睡梦中的旅客。可是在阳关,干裂的阳光晒得脸皮疼,滚烫的风吹干了身体里的水。莫高窟绚烂的壁画,精美的彩塑,精彩的故事,九色鹿舍己救人,丑公主变美,千手千眼观音菩萨……还在脑海里浮动,还想伸出手摸一下,惊讶地张大的嘴还没有合拢,让脑仁疼的喇叭声就钻进了耳朵。
党河水安静地流淌,河岸上草木舔着水花自顾自地灿烂、摇曳、生长,还有鸟雀的栖息,这些繁盛的树木只想着在太阳出来之前吸足水分。我沿着河岸前行,荡荡的河水仿佛东汉“草圣”张芝[注]家的墨池。张芝、张昶兄弟俩每天清晨就开始练习书法,他们在临河的墨池里蘸一蘸笔尖就把水染黑了,还有他们家的庭院,到处挂满布,写着黑字的布在风里飘扬。这些集“月之阴柔,日之阳刚,地之宽厚,天之崇高”于一体的字,像篝火呼啦啦燃烧在黑夜,像七月敦煌的天气滚烫、蒸熟生硬的果实。
河岸上传来牛的哞叫声,几条狗在撕咬、打架,岸上是一排排土坯房子,有烟囱冒出了烟,是出租车司机刘家的,昨晚回家迟,几个来自远方的年轻游客租车去了雅丹。这是古丝绸路南道北干线,由此向西沿白龙堆沙漠穿越罗布泊直到楼兰,再从楼兰到若羌转入丝路南道,这条道为沙漠路。他们正值青春,对荒无人烟、没有生命、岑寂的沙漠充满梦想,记忆里肯定流淌着许多五彩缤纷的故事。中国古代旅行家法显,欧洲探险家斯文·赫定,就像天边升起一抹霞光,倏地扩张到整个天空,然后在他们心灵深处扎根了。
年轻的斯文·赫定第一次从喀什到若羌,翻越塔克拉玛干沙漠,在走进沙漠后,目之所及,全是荒芜贫瘠的黄色沙丘,茫茫沙海铺在眼前。干得能当火种的沙,掀起了干热的风,疯狂吸食身体里不多的水分,皮肤干成了牛皮纸。干渴让他的队伍分崩离析。在见不到一丝绿色和动物的痕迹、只有冷峻的星光划破死寂的夜里,斯文·赫定抽出沙里的身子,听着自己在沙上发出的沙沙声,趁着凉爽的黑夜前行。当他靠吃野草、树叶、芦苇芽、苦水里的小蝌蚪走出沙海,把最后一盏点亮的灯放在沙丘上时,多么希望失散的人员、骆驼、狗儿能跟来,沿着他留下的足迹,找到于阗河……就这样,百年来,斯文·赫定也成了塔克拉玛干沙漠深处的故事,吸引着无数人去寻找。他留下的足迹、灯盏像航标、浮标在沙海上漂动,像一枝水莲立于沙浪上。
党河岸上,土坯房上,许多烟囱冒起了烟,人们在告别昨夜的梦吗?我听见有音乐从窗户里流出,有诵读声飘在村庄上空,这些美好的声音,让缀满果实的杏树心花怒放,让李广杏子像海绵球在墙上蹦跳。天空万里无云,无边无际,向四面舒展开去,丰沛、连绵、密集的阳光赋予敦煌灿烂无比的早晨。
光焰四射的晨阳,漫过党河岸,洒向熙攘的城市、丰饶的村庄。在燃烧的阳光里,棉花裂开坚硬的外壳,纷披的李广杏子星星似的闪烁在绿叶里,大片大片杏林就是深邃的夜空。
敦煌已经醒来,而且喧嚣起来,我听见有人诵读:
敦者,大也;煌者,盛大也
黎明中起身的敦煌——
鸣沙山就在前面,太阳这个大火球,早把那点湿气舔干净了,沙子开始发烫,远处沙丘脊线上腾起火焰。这片沙漠背对海洋,这里的人们多么希望面朝大海啊。人们还记得大海的、海草的味;海浪拍击礁石的声音;水花溅在脸上热辣而冰凉,激起尖利的惊叫声。来自海边的人们在鸣沙山上逍遥,胀鼓鼓的风扫过一尘不染、炫目的沙丘,裹着花色披肩的年轻人吹着口哨,光屁股的孩子们在沙上厮打,从山脊上滚下来再爬上去。有马厩的气味飘来,有清脆的铃铛声传来,浩浩荡荡的驼队从更远的沙脊上走来,训练有素的骆驼,驮着欢乐的、唱着歌、尖叫的、互相拥抱汗津津的人们,穿越喷着火的沙丘。
整个白天,鸣沙山持续不断的喧嚣、欢乐、呐喊,让平日里心情沉郁的人,此时容光焕发,心里不禁产生一种明媚的期望。
黄昏降临,血色的太阳蔓延到身边。月亮升起,天边上星星亮起来。凉风吹来,沙丘上起了微波,似细细的音乐,轻轻踩过梦境。
(选自《人民日报》)
(注)张芝,东汉时敦煌酒泉人,曾在敦煌苦练书法。

高三语文现代文阅读困难题查看答案及解析
阅读下面的文字,完成各题。
材料一:
黄河之滨,白塔山下,伫立着一座非物质文化遗产陈列馆,阮熙越就在这里坚守着。阮熙越是兰州阮氏刻葫芦第四代传人,其作品被英国等国家博物馆收藏,她的家族传承刻葫芦技艺已有百年历史。
谈及刻葫芦民间艺术现状,阮熙越表示,这些年来当地政府在民间艺术上投入很大,很多民间传统工艺的生存环境有了改观。据兰州市文化和旅游局社会文化处介绍,近两年,政府加大对当地民间艺术的保护力度,现在已建成4个“非物质文化遗产”保护基地,建立了44个“非遗”传习所,给予市级以上“非遗”传习所每年5000元到8000元的资金扶持,提供免费的传习场地,还给予资金支持或提供交流机会去国外展示展演。
(选自《甘肃兰州:政府多措施保护民间工艺实现文化传承》)
材料二:
对待传统手工技艺程式化和已成为法度套路的东西,如法式、规矩、惯例、艺诀等,我们应该加以尊重,不要以“创新”的名义或为经济效益而轻率地改变。创新不是告别传统的使用功能,而是以适应当代生活需要为突破点,在不违背手工业生产规律,不扭曲其自然衍变趋势的前提下,生产符合现代人审美观念的产品。
成功的设计能够创立新的“典范”,引领新的手工艺潮流与时尚。而设计的主要任务是培育民族工艺品牌,重塑民族的工艺意象。但是,这么多年,中国一直都缺乏叫得响的国际一流“手工品牌”,原因在于掌握技艺的民间手工艺人,大都年龄偏大,文化水平有限,视野思维也不够开阔,而年轻一代则在技艺上不够成熟,这些阻碍了现代设计与传统民间手工艺的融合。
科技代替不了双手,后工业时代更需要“工匠精神”,这样产品才有温度。手艺人是民间手工艺的传承者,也是“工匠精神”的践行者,因此振兴传统民间手工艺,传承“工匠精神”,首先要给予职业手艺人以职业尊重。为此,有学者指出,完善制度建设势在必行,还有学者建议学习日本的手工艺人才培养方式——先培养其基本心性、品德,再进行技艺传承,同时将“工匠精种”融入现代教育体系中,培养现代学徒。
(摘编自《传统民间手工艺如何走出“深闺”》)
材料三:
凤翔城关镇六营村是凤翔泥塑发源地,经过不断地完善加工,逐步形成了今天的彩绘泥塑。当我们打开“中国泥塑网”时,便可以看到绚丽多姿的泥塑产品正在进行当今最迅捷最远程的网上交易。统计资料显示,近些年来仅泥塑产业一项就带动了宝鸡地区旅游等相关产业收入近千万元,当地村民把这项传统的民间工艺发展成为了六营村的主要致富手段。
可喜消息的背后伴随着新的忧虑。市场经济挽救了民间艺术,同时也激励它发生新旧交替的巨变,这巨变会不会正是原始艺术特征的可悲的消弭过程的开始呢?我们如何才能尽可能长久地保持民间艺术的原汁原味呢?
(摘编自《产业化经营让凤翔彩绘泥塑走向世界》)
材料四:
由于手工工艺品主要以手工制作为主,既费时又耗力,所以手工工艺品大多都是以个人生产经营为主,生产规模相对较小。虽然有一部分的手工工艺品进入国际市场,但是我国手工艺品的整体发展水平还不是很成熟,其生产规模和经营的规模化、市场化以及产业化程度相对较低,所以市场的核心竞争力也较低。
目前,传统手工艺的生产和形式严重脱离了人们的生活实际,使得传统手工艺品逐渐萎缩。现代人的生活方式和审美观念发生了很大的改变,尤其是“互联网+”时代的到来,消费者的审美越来越国际化、个性化、生活化,对那些造型老套、形象土气、材质普通、品相不佳的“非遗”手工产品提不起兴趣,这就倒逼手工艺术家们要从传统思维定式中走出来,要融入现代审美情趣、融合当代流行工艺、融汇当下时尚元素,打造出令消费者眼前一亮,而又爱不释手的好作品、好产品。
(摘编自《传统手工艺活态传承的困境与出路》)
1.下列对材料相关内容的理解,不正确的一项是
A.对待传统手工技艺程式化和已成法度套路的东西,如法式、规矩、惯例、艺诀等,我们应该加以尊重,不要以“创新”的名义或为经济效益而做出任何改变。
B.手艺人是“工匠精神”的践行者,在振兴传统民间手工艺方面起着至关重要的作用。因此,重视民间手工艺,首先要重视手艺人。
C.材料三表明,市场经济不但可以挽救民间艺术,使其获得新的发展,还可以带动相关产业的发展,成为致富的新途径。
D.手工工艺品要想获得新的生命力,需要手工艺术家们从传统思维定式中走出来,满足现代人的生活方式和审美情趣。
2.下列对材料相关内容的概括和分析,正确的一项是
A.中国的民间手工艺人,无论年龄大小,其自身大都存在着一定的不足,导致了中国缺乏国际一流的民族工艺品牌。
B.在不违背手工业生产规律的前提下,融入现代审美情趣后,适应当代生活需求,就能打造出令消费者眼前一亮的好产品。
C.在市场经济的帮助下,民间艺术不但焕发出了新的活力,还带动了一些地区的经济发展,所以市场经济对民间艺术来说,是百利而无一害的。
D.由于手工艺品主要以手工制作为主,既费时又耗力,生产规模相对较小,所以必须走机械化生产道路,以提高生产效率。
3.你认为怎样才能让民间手工艺走出困境,传承并发扬光大?请结合材料谈谈你的看法。

Will our parents check our homework? Not really. Since having already growing up, we can’t act like little baby and rely on our parents all the time.
When I was in Grade Three, my parents asked us to check my homework by myself. I don’t know what to do in that time, so I cried. Before that, I got used to correcting my own homework and became more independent.
Check homework by ourselves is very good habit. It can not only help us find mistakes in exams more easy but also let our parents worry less about our studies. Because parents will leave us some day, so we should learn to do everything by ourselves.

高三英语七选五中等难度题查看答案及解析
The beginnings of life provide scientists with some of the most difficult questions on modern science. Our knowledge of the development of cells, from which all forms of life are made, is not complete because we do not understand very well conditions on our planet four billion years ago. Why and how did cells first appear? Was this very likely to happen under the conditions then, or was it due to chance? Might this happen in other places in the universe?
A group of scientists at London University are trying to answer these questions. They started by studying the way in which the first cells on Earth might have been formed. Next they will use powerful new telescope to look at places far away in the universe. The scientists hope that the results will improve our understanding of the development of life on Earth and help us to find life on other planets.
Dr. Nick Lane, who is in charge of the team, has suggested that four billion years ago warm water springs on the floor of the earth ocean might have helped create life. Each spring consists of tiny connected holes that water passes through. The team have created models of these springs in their labs. You have found that they encourage chemical reactions between hydrogen in the liquids that come out of them and the carbon dioxide in the sea water. These chemical reactions can create the “building blocks” of life, these building blocks are not living themselves, but when they are enough of them joined together in the right way, they can make living things. The water in the system of springs move the building blocks around until there are a lot of them in a small area. Things that look very much like real living cells can be made in this way.
These reactions and changes show us how life on earth and on other planets could begin. When sea water goes through tiny holes in the earth’s surface, it gets very hot and causes a chemical reaction with rocks. When this very hot water goes back up and meets cold sea water again, other chemical reactions happen. Lane explains, “The conditions needed for life are rock, water and carbon dioxide. This could be found on millions of exoplanets (planets beyond solar system), so basic life should be everywhere.”
1.What can we learn from the fourth paragraph?
A.Rock, water and carbon dioxide are three things to make life.
B.How different chemicals mix together to produce cells.
C.Amazing reactions are made by hot sea water and cold sea.
D.Life should be seen everywhere in the exoplanets.
2.What does the underlined word “spring” in the third paragraph mean?
A.A place where liquid comes out of the earth.
B.A place where cells are easily born.
C.A place where building blocks of life can be found.
D.A place where hydrogen and carbon dioxide are combined.
3.Why is the scientist very sure that there must be life on exoplanets?
A.We have had enough knowledge about the Universe.
B.The new powerful telescope can help us find cells on the other planets.
C.The ingredients for life are basic and should be all over the universe.
D.Chemical reactions can happen everywhere in the universe.
4.What is the best title for the text?
A.Changes at the Bottom of the Sea B.How Life Starts always puzzles the scientists
C.Search for the Start of Life D.Life Exists on Millions of Exoplanets

Dolphins make a wide range of communicative sounds and also display something called vocal learning, which is the ability of an animal to modify its vocalization(声音)based on its experience with other animals.
Mainly, there are three types of dolphin vocalizations: whistles, clicks, and burst pulses. People still don’t know their precise meanings, but people do know that dolphins use their vocalizations as a way to communicate with one another.
The dolphin whistles are very high frequency sounds, partially above the range of human hearing. What’s fascinating is that each dolphin has a signature whistle, which is unique to each individual dolphin. It allows them to call to or identify each other.
No two signature whistles are same-sounding. As members of the same family, their signature whistles have similar elements. Dolphins use them as a contact calls. They call to each other while travelling and searching for food. It helps keep the group together and helps mother and children find each other. The uniqueness of each dolphin’s signature whistles is just like the following example: if you were travelling in the forest with one other person who was just out of sight, you would call out, “Are you there?” and the other person would respond. But if there were several people in the forest, you would have to call that person’s name.
In addition to whistles, dolphins produce clicks, which are actually sonar or sound waves. They use clicks to communicate, but more importantly to navigate and hunt. How? The sonar clicks bounce off objects and then the dolphins convert the incoming signals into a three dimensional picture, a mental map of what’s around them. The clicks are extremely sensitive and accurate. The sonar clicks are also very strong. One reason why dolphins swim side by side is to avoid interference from each other’s sonar clicks. Interference would be confusing and it would prevent them from getting an accurate picture of their surroundings. And what’s interesting is dolphins will turn off their sonar when another dolphin passes in front.
The third category of dolphin vocalizations is burst pulses. These are all the other sounds the dolphin makes-squeals, barks, groans and so on. Burst pulses are used to display dislike, claim their living area and attract a mate.
1.What is the reading passage mainly about?
A.How dolphins produce songs they want.
B.How dolphins teach their young to identify signature whistles.
C.How dolphins swim side by side to hunt.
D.How dolphins communicate with one another in various ways.
2.According to the reading passage, why do dolphins travel side by side?
A.To show how united they are as a group.
B.To hear each other’s signature whistles.
C.To avoid interference with other dolphins’ sonar clicks.
D.To keep mothers close to their young.
3.What does the underlined word “example” in paragraph 4 illustrate?
A.The differences between land and marine mammals.
B.The importance of burst pulses as a way dolphins communicate.
C.One reason dolphins travel in large groups.
D.One way dolphins use signature whistles.
4.Which of the following statements is NOT right according to the passage?
A.Human can easily hear the dolphin signature whistles.
B.A male dolphin shows his love to a female by using burst pulses.
C.Dolphins know what is around them by analyze the sonar they receive.
D.Dolphins can adjust their vocalizations to the surroundings.
