一把雨伞阅读含答案参考一把雨伞阅读含答案参考「篇一」从前,有个商人有外苦心经营多年,终于攒下了大宗财富,准备告老还乡,结束半生的漂泊辛劳,回家与妻子团聚,置田购房,安度晚年。
当时时局动荡,路途遥远,路上常有劫匪。
商人不敢露富,只得穿一袭灰布长衫,一双布底鞋,扮做一个餐风露宿的行路人。
商人特地购了一把弯头笔下枘油纸雨伞,如此这般,貌似贫寒之士,肩挎一条褡裢,手提这把雨伞,轻轻松松地上路了。
这天中午,商人来到了成都近郊的唐家寺,见是一个平常的小镇,鸡安犬宁人面善,商人便走到一家面馆,叫煮一碗面条来,吃了好赶路。
成都担担面闻名遐迩,一碗面条七红八绿,作料丰足,商人香喷喷地吃了起来。
没想到肚子吃饱了,一阵倦意却涌了上来。
小店生意一般,只有三五食客,倒也不吵闹。
于是,商人在桌旁打了一个盹。
(a)一阵清凉的风吹醒了商人,他抬头一看,小店内已不空无一人,门外却淅淅沥沥下起了小雨。
商人揉揉脸颊,突然暗叫不好,自己的那把油纸伞已不见踪影!一阵冷汗霎时冒了出来。
就想,定是在他打盹的时候,老天偏偏下起了雨,而那些食客急于出门,其中哪个见他睡着了,就顺手牵羊把他的伞取走了。
商人将随身零钱清点了一番,沉吟片刻后,决定自己该做什么和怎么做了。
他叫来面包掌柜的,说自己看中了这个平静安宁的镇子,决定就在这里住下,开个小铺维生,请帮忙找一间房子。
掌柜的也是个和善之人,说你开什么样的铺子?要多大的房子?我帮你找就是。
商人说:“身无长技,只会修伞补帽。
小小手艺人,租不起大房子,只是最好能够在交通要道上。
”掌柜的笑道:“当然,修乎补帽应该在路边。
”于是很快帮他找了一处房子,商人便用仅有的钱在唐家寺开起了修伞铺。
商人待人客气,心灵手巧,天亮天门,天黑关门,很是个规矩人的样子,没过多久,他小小的.修乎铺子便受到当地人的好评,人们都愿意把伞拿给他修理,哪怕多起两三里路。
商人的伞铺算是立住了,可谁也不知道这个小手艺人是腰缠万贯的富商,更不知道他每天谦和的笑脸下,掩藏着紧张焦灼的心。
高考语文《占梦人》阅读理解含答案阅读下面的文字,完成下面小题。
占梦人加西亚·马尔克斯上午九点,我们正在哈瓦那·里维埃拉酒店的露台上享用早餐,烈日下,海水突然掀起一个巨浪,把沿着海堤大道行驶的和停在人行道上的几辆汽车抛到半空中,其中一辆嵌进了酒店的侧墙。
整个上午谁也无暇顾及嵌入酒店侧墙的那辆车,大家都以为它原先是停在人行道上的。
但当起重机把车从墙洞里取出来时,人们发现驾驶座上有一具系着安全带的女性尸体。
这野蛮的一击使她粉身碎骨,面容已无法辨认,靴子撕裂了,衣服也成了碎片,手上戴着一枚镶着绿宝石眼睛的蛇形金戒指。
警察证实,她是新任葡萄牙大使的管家。
①这是一个关键的信息,因为我担心那是一位我难以忘怀的故人,虽然我一直都不知晓她的真实姓名。
她右手食指上戴着一枚同样的戒指,在那个时代很不寻常。
认识她是在三十四年前的维也纳,她大约三十岁,保养得不好,应该不曾美丽过,就已提前开始衰老。
不过她是个很有魅力的人,同时也非常可怕。
她从没提起过自己的真实姓名,我们总是称呼她:弗劳·弗里达。
刚一认识,我就冒冒失失地问她,她是如何立足并发迹的。
她掷地有声地回答:“我受雇做梦。
”事实上这的确是她唯一的职业。
从她牙牙学语开始,就在家庭中养成了良好的习惯,每天在早餐前讲述自己的梦,这时候能回忆起的内容保存着最纯粹的预见性。
七岁时,她梦见一个弟弟被激流冲走。
全然出于迷信,母亲禁止那个孩子在小溪里游泳,虽然那是他最喜欢做的事。
但是弗劳·弗里达对于解梦已经有了一套自己的体系。
“这个梦的含义,”她说,“不是说他会溺水而亡,而是说他不应该吃甜食。
”这似乎只能解释为她不怀好意,因为对于一个五岁的孩子来说,离开了周末甜点,简直活不下去。
然而他们的母亲已经对女儿的预言天赋深信不疑,一丝不苟地遵照这一警告执行。
但是某天她一个疏忽,那孩子在偷吃一颗糖球时噎住了,谁也无力回天。
②弗劳·弗里达从没想过这项天赋可以作为职业,直到在维也纳残酷的严冬,生活扼住了她的咽喉。

《读者》二十年来最具影响力的十篇文章(六)一碗清汤荞麦面(1989.11)一碗清汤荞麦面(1989.11)文:(日本)玲木立夫一对于面馆来说,生意最兴隆的日子,就是大年除夕了。
北海亭每逢这一天,总是从一大早就忙得不可开交。
不过,平时到夜里12点还熙攘热闹的大街,临到除夕,人们也都匆匆赶紧回家,所以一到晚上10点左右,北海亭的食客也就骤然稀少了。
当最后几位客人走出店门就要打烊的时候,大门又发出无力的“吱吱”响声,接着走进来一位带着两个孩子的妇人。
两个都是男孩,一个6岁,一个10岁的样子。
孩子们穿着崭新、成套的运动服,而妇人却穿着不合季节的方格花呢裙装。
“欢迎!”女掌柜连忙上前招呼。
妇人嗫嚅地说:“那个……清汤荞麦面……就要一份……可以吗?”躲在妈妈身后的两个孩子也担心会遭到拒绝,胆怯地望着女掌柜。
“噢,请吧,快请里边坐。
”女掌柜边忙着将母子三人让到靠暖气的第二张桌子旁,边向柜台后面大声吆喝,“清汤荞麦面一碗——!”当家人探头望着母子,也连忙应道:“好咧,一碗清汤荞麦面——!”他随手将一把面条丢进汤锅里后,又额外多加了半把面条。
煮好盛在一个大碗里,让女掌柜端到桌子上。
于是母子三人几乎是头碰头地围着一碗面吃将起来,“咝咝”的吃吸声伴随着母子的对话,不时传至柜台内外。
“妈妈,真好吃呀!”兄弟俩说。
“嗯,是好吃,快吃吧。
”妈妈说。
不大功夫,一碗面就被吃光了。
妇人在付饭钱时,低头施礼说:“承蒙关照,吃得很满意。
”这时,当家人和女掌柜几乎同声答说:“谢谢您的光临,预祝新年快乐!”二迎来新的一年的北海亭,仍然和往年一样,在繁忙中打发日子,不觉又到了大年除夕。
夫妻俩这天又是忙得不亦乐乎,10点刚过,正要准备打烊时,忽听见“吱吱”的轻微开门声,一位领着两个男孩的妇人轻轻走进店里。
女掌柜从她那身不合时令的花格呢旧裙装上,一下就回忆起一年前除夕夜那最后的一位客人。
“那个……清汤面……就要一份……可以吗?”“请,请,这边请。
ENGLISH ON CAMPUS2023年12期总第660期课程思政融入大学英语课堂教学的实践研究——以《新视野大学英语》为例摘 要:课程思政理念指导下的大学英语课堂,承担着传授语言知识技能和进行思政教育以促进立德树人的双重任务。
大学英语教师应该不断提升自身的思政素养,提高课程思政教学能力,充分挖掘教材中所蕴含的思政元素,找到适当的切入点将思政元素融入课堂教学,有效发挥大学英语课堂的全方位育人功能。
本文以《新视野大学英语》为例,阐述了大学英语教学中融入课程思政的重要意义、《新视野大学英语》教材使用概况,具体探讨如何将思政元素融入大学英语课堂教学,以实现大学英语教学价值塑造、知识传授、能力培养的有机统一。
关键词:课程思政;大学英语;教学实践作者简介:杨建峰(1989.01-),女,新疆昌吉人,昌吉学院,助教,研究方向:语言学、英语教学;徐红梅(1972.03-),女,山东栖霞人,昌吉学院,副教授,研究方向:语言学、英语教学。
一、大学英语教学中融入课程思政的意义(一)符合现阶段对思想政治教育的基本要求2016 年12月,习近平总书记在全国高校思想政治工作会议上指出,要用好课堂教学这个主渠道,思想政治理论课要坚持在改进中加强,提升思想政治教育亲和力和针对性,满足学生成长发展需求和期待,其他各门课都要守好一段渠、种好责任田,使各类课程与思想政治理论课同向同行,形成协同效应。
课程思政是一种教育理念,要求教师在专业课程教学中寻找思政教育的切入点,进行思想政治教育的创新实践。
在大学英语教学中融入课程思政,并充分挖掘大学英语课程内容中的思政元素,是促进专业课程教学与思想政治教育融合的一种大胆实践,符合现阶段对思想政治教育的基本要求,是从英语教学出发,提升和改善学生思想认知状态和英语学习态度的重要途径。
(二)符合传承和弘扬中华优秀传统文化的基本需求大学英语教学虽然在形式上是以教授西方文化为主的教学,但从大学生的角度来说,在大学英语教学中融入中华优秀传统文化方面的思政教育内容,有利于传承和弘扬中华优秀传统文化。

C(35 minutes)Passage 1The novelist Robert Herrick was born in Cambridge, Massachusetts, on April 26, 1868. His oldest American ancestor, a nephew of the author of Hesperides, had settled at Salem in 1638; he was related to the Hales, the Mannings, the Hawthornes, and the Peabodys; his immediate forebears were lawyers, teachers, and clergymen. At Harvard, he was a contemporary of Santayana. William Vaughn Moody,Norman Hpgood, and Robert Morss Lovett; he nearly wrecked the Harvard Monthly when he sullied its chaste pages with the first English translation of lbsen's ludy from the Sea. His teaching began at the Massachusetts Institute of Technology, but William Rainey Harper lured him to the new University of Chicago, where he remained officially for exactly a generation and where his students in advanced composition found him terrifyingly frigid in the classroom but sympathetic and understanding in their personal conferences. During his later years the spot of earth dearest to his heart was York Viliage, Maine, but after his retirement from teaching he brought his career to a rather amazing close as government secretary of the Virgin islands, He died at St. Thomas on December 23, 1938.1. To which of the following families was Herrick related?(A) The Santayanas(B) The Hawthornes(C) The Moodys(D) The Hapgoods2.In lines 3-4, the phrase "immediate forebears" could best be replaced by which of the following?(A) closest ancestors(B) wealthiest relatives(C) cleverest kinsmen(D) earliest forefathers3. Which of the following is NOT mentioned as a profession of Herrick's relatives?(A) Farmer(B) Teacher(C) Clergyman(D) Lawyer4. Herrick moved to the University of Chicago at the request of(A) the Hales(B) the Mannings(C) Robert Morss Lovett(D) William Rainey Harper5. According to the passage, Herrick's students thought he was(A) gifted in English translation(B) unfair in his grading(C) easy to understand(D) kind during personal contact6. In which of the following activities was Herick involved during the last years of his life?(A) University teaching(B) Government work(C) Translating(D) LecturingPassage 2There are two main kinds of sloth; the two-toed and the three-toed. Of these, the three-toed is considerably the more slothful. It hangs upside down from a branch suspended by hook-like claws at the ends of its long bony arms. It feeds on only one kind of leaf, Cecropia, which happily for the sloth grows in quantity and is easily found. No predators attack the sloth-few indeed can even reach it-and nothing competes with it for the Cecropia. Lulled by this security, it has sunk into an existence that is only just short of complete torpor. It spends eighteen out of twenty-four hours soundly asleep. It pays such little attention to its personal hygiene that green algae grow on its coarse hair and communities of a parasitic moth live in the depths of its coat producing caterpillars which graze on its mouldy hair. Its muscles are such that it is quite incapable of moving at a speed of over a kilometer an hour even over the shortest distances and the swiftest movement it can make is a sweep of its hooked arm. It is virtually dumb and its hearing is so poor that you can let off a gun within inches of it and its only response will be to turn slowly and blink. Even its sense of smell, though it is better than ours, is very much less acute than that of most mammals. And it sleeps and feeds entirely alone.1. The purpose of the passage is to(A) compare the two-toed and the three-toed sloths(B) explain the parasitic relation of a type of moth to the sloth(C) describe the behavior of the three-toed sloth(D) condemn the way the sloth takes care of itself2. It can be inferred from the passage that the sloth uses its hooked claws mainly to(A) hang on tree branches(B) clean its coat(C) catch prey(D) swing from one place to another3. What does the sloth eat?(A) Caterpillars(B) Cecropia(C) Moths(D) Algae4. How does the sloth spend most of its time?(A) Eating(B) Sleeping(C) Grooming itself(D) Finding food5. It can be inferred from the passage that if a person makes a loud noise near a sloth, the slothwill(A) attack the person(B) run away as fast as it can(C) show little response(D) become deaf6. The author's discussion of the sloth focuses primarily on the animal's(A) solitary nature(B) physical handicaps(C) diet(D) inactivityPassage 3The Montessori method of educating children is guided by perhaps a half–dozen major principles of education. The first affirms the biological programming of child development, the child's capacity for self – realization, for "auto-education." The second calls for "scientific pedagogy." A science of childhood based on observation. The third demands a natural environment in which self-development can be expressed and observed. Montessori believed that the school could be made into such an environment, thus becoming a laboratory for scientific pedagogy. This environment should be determined scientifically. In order to expand, children, left at liberty to exercise their activities, ought to find in their surroundings something organized in direct relation to the children's internal organization. All of these principles imply the next, which Montessori calls the " biological concept of liberty in pedagogy": the child must be free to act spontaneously and to interact with the prepared environment. The entire program is concerned with the individual child; the spontaneity, the needs, the observation, the freedom are always those of the individual. Finally, the modus operandi of the method is sensory training.1. Which of the following is the best title for the passage?(A) Principles of the Montessori Method(B) Modern Principles of Education(C) Results of the Montessori Method(D) Stages of Child Development2. In line 6, the phrase "such an environment" refers to which of the following kinds ofenvironment?(A) Biological, accompanied by specimens(B) Scientific, accompanied by experiments(C) Pedagogical, in which ideology prevails(D) Natural, in which self-expression prevails3. According to the passage, the Montessori method focuses on(A) the individual child(B) pairs of children(C) small groups of children(D) large groups of children4. I t can be inferred from the passage that the Montessori method was named after a(A) school(B) town(C) person(D) book5. W hich of the following would NOT be advocated by the Montessori method?(A) Tightly controlling children's group activities(B) Carefully teaching children to listen and observe(B) Permitting children to work at their own pace(C) Allowing children to speak out at will during classesIn an experiment designed to study the effect of majority opinion, even when it is contrary to fact, small groups of subjects observed a standard straight line, and then judged which of three other lines equaled it in length. One of the other lines was longer, one shorter, one equal to the standard; the differences were great enough that threshold judgments were not involved. All but one member of each group had been instructed to agree upon a wrong answer for a majority of the trials. The experimental subject was thus pitted against a majority, and the subject's problem was whether to disagree with the majority, or to doubt his or her own judgment and agree. Many subjects refused to change, and continued to hold to their independent appraisals. But a substantial number yielded under pressure from the others' apparent judgments. The amount of yielding depended upon the clarity of conditions (lack of clarity led to conformity to majority opinion), individual differences, and the size and unanimity of the opposition. With the opposition of only one other person there was very little yielding; with tow against one the amount of yielding became pronounced; and a majority of three was nearly as effective as larger majorities against the lone dissenter.1. W hat does the passage mainly discuss?(A) The accuracy of threshold judgments.(B) The inability of groups to estimate correct line length.(C) The impact of majority opinion on the judgment of an individual.(D) The necessity of clear conditions in conducting successful experiments.2. A total of how many lines were shown to each group of subjects?(A) Two(B) Three(C) Four(D) Five3. W hy did all but one of the members of each group choose the wrong line?(A) They could not accurately judge which lines were equal in length.(B) They were told to do so for the purposes of the study.(C) They wanted to humiliate the person who disagreed.(D) They did not understand the instructions.4. I t can be inferred from the passage that the main purpose of the experiment was to examine thetendency that many people have to(A) compete(B) conform(C) criticize(D) communicate5. T he experiment described in the passage was most likely carried out by(A) physicists(B) mathematicians(C) linguists(D) psychologistsThis vertical movement of the fieldstones is not simply an artifact of soil erosion, it is the result of frost heaving. In the fall the soil freezes first beneath stones, because stones are a better conductor of heat than soil. Or, put another way, soil is a better insulator than rock in a sea of insulation, stones are chilly islands.Because most glacial till has a fairly high water content, ice forms beneath fieldstones when they freeze, and the expansion of this ice forces them upward. Even when the ice thaws, the stones do not return to their original positions because during thawing particles of soil seep into the cavity beneath, partially preventing the stones from dropping. Like a ratchet on a car jack each freeze-thaw cycle gradually lifts the fieldstones toward the surface. Ina very cold winter there may actually be two thrusts per freeze. Ice expands when it initially forms, but as the temperature plummets, the ice contracts. In the reverse process, when this very cold ice finally melts, it must expand a second time, pushing the stone once more.In theory, the upward movement of fieldstones should result in pure soil, all the stones above the frost line having been pushed to the surface and carried away. What a vision! Acres of pure, deep soil and crowbars rusting away unused. Alas, the fastest stones move only an inch or so a year, and most are orders of magnitude slower.1. W hat does the passage mainly discuss?(A) The effect of frost heaving on stones(B) The water content of various types of soil(C) Factors affecting the rate of ice expansion(D) Seasonal variations in ground temperature2. W hat statement was most probably made in the paragraph preceding this pasage?(A) Pure soil is quickly eroded.(B) Fieldstones are lifted to the top of the soil.(C) It is not easy to move stones from fields.(D) Ancient cultural artifacts are buried deep in the soil.3. W here does the soil freeze first in the fall?(A) On the tops of stones(B) In areas of pure, deep soil(C) Under rocks(D) On islands4. I n the first paragraph, the author gives an example of(A) glacier movement(B) soil erosion(C) climate change(D) heat conduction5. A ccording to the passage, why do fieldstones remain raised in the soil when the ice thaws?(A) Melting ice erodes the soil around them.(B) Soil fills in under them(C) They remain in a frozen layer of topsoil.(D) The frost line under which they are resting moves upward.6. T he author refers to a car jack in an analogy that illustrates how(A) stones are pushed upward(B) heavy rocks press down on deep levels of soil(C) a crowbar is used to remove stones from soil(D) automobile parts freeze in cold weather7. W hich of the following conclusions is supported by the third paragraph?(A) Stones above the frost line will quickly be pushed upward.(B) The number of stones surfacing each year is decreasing.(C) Acres of pure, deep soil regularly result from frost heaving.(D) New stones will continue indefinitely to surface at a slow rate.8. I n line14, the author exclaims "What a vision!" to express an attitude of(A) fear(B) disgust(C) enthusiasm(D) romancePassage 6A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun's very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is liberated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and, in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of years.The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun, to be re-emitted at slightly longer wavelengths. This radiation, in its turn, is absorbed and re-emitted. As the energy filters through the layers of the solar interior, it passes through the x-ray part of the spectrum, eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space, without being absorbed further by solar atoms. Avery small fraction of the Sun's light and heat is emitted in such directions that, after passing unhindered through interplanetary space, it hits the Earth.1. W hat does the passage mainly discuss?(A) the production of solar light and heat(B) the physical and chemical nature of life(C) The conversion of hydrogen to helium(D) Radiation in the x-ray part of the spectrum2. A ccording to the passage, energy is released in the Sun when(A) helium atoms bind with each other(B) gamma radiation escapes from the spectrum(C) radiation is absorbed by helium(D) nuclei of hydrogen atoms collide3. T he passage indicates that, in comparison to radio waves, gamma waves(A) produce louder sound(B) are less magnetic(C) do not form in the Sun's center(D) are not as long4. A ccording to the passage, through which of the following does the energy released in the Sunpass before it becomes light?(A) The x-ray part of the spectrum(B) Electromagnetic space(C) The solar surface(D) Interplanetary space5. I t can be inferred from the passage that the Sun's light travels(A) through solid objects in space(B) in many different directions(C) more slowly than scientists previously believed(D) further in summer than in winter。
