电阻 1、什么叫导体?什么叫绝缘体? 生活中常见的导体有哪些?绝缘体有哪 些? 2、生活中常见的导线是用什么材料做成的? 金属铁既多又便宜,为什么不用铁来做导 线呢? 复习提问: 1、定义:在物理学中,用电阻来表示导体对电流阻碍作用的大小 。

通常用字母R表示 3、电阻的单位是欧姆,简称欧,符号是Ω。

4、常用单位:千欧(kΩ) 兆欧(MΩ) 1 kΩ=103 Ω 1 MΩ=106 Ω 一、电阻 2、元件符号: R 欧姆简介: 欧姆(Georg Simon Ohm,1787~1854年)是德国物理学家。

生于巴伐利亚埃尔兰根城。

欧姆定律及其公式的发现,给电学的计算,带来了很大的方便。

人们为了纪念他,将电阻的单位定为欧姆,简称“欧”。

1854年7月,欧姆在德国曼纳希逝世。

在电子技术中经常用到具有一定电阻值的元件 --电阻器,也叫定值电阻。

它的外形多种多 样,但作用是相同的。

下面就是几种定值电阻: 各种电阻器 一、提出问题: 影响导体电阻大小的因素会有哪些? 二、进行猜想 猜想也要有一定的依据,可不能瞎猜哟! 猜想一 导体的电阻可能与导体的材料有关 猜想二 导体的电阻可能与导体的长度有关 猜想三 导体的电阻可能与导体的粗细有关 猜想四 导体的电阻可能与导体的温度有关 三、设计实验方案 你怎样知道导体电阻的大小?你能设计一个合理的电路吗? 通过比较灯的亮暗来判断,如灯亮,则对电流阻碍作用小,电阻小。

通过比较电流表中电流的大小,如电流大,则对电流的阻碍作用小,电阻小。

既可比较灯的亮暗,也可比较电流的大小实验过程中需记录的内容有哪些?你能设计一张表格来表示吗? 导体 灯的亮暗 电流示数 电阻的大小 材料 长度 粗细 控制变量法:一个物理量可能与多个因素有关,我们必须一个一个因素来研究。

研究时,只让其中一个因素改变,其余因素要保持不变。

思考:一个物理量可能与多个因素有关时,如何展开研究? 三、设计实验方案 1.探究导体电阻与材料的关系。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

我们每个人都生活、工作在这个地球的一隅,在一个小圈子里活动。

我们对具有广泛影响的公共事件充其量只能了解某个方面或某一片段。

我们的见解不可避免地涵盖着要比我们的直接观察更为广泛的空间、更为漫长的时间和更为庞杂的事物,这些见解是由别人的报道和我们自己的想象拼合在一起的。

然而,即使是目击者也不可能原原本本地再现事件的全貌,因为经验似乎表明,他本人会对事后减弱了的现场印象作些添枝加叶的处理。

实际上,更常见的并不是他凭想象去描绘一个事件,而是对它进行改编。

绝大多数事实似乎都在某种程度上经过了有意加工。

一篇报道乃是当事人和知情者的共同产物,其中那个旁观者的角色总是带有选择性倾向,通常还会带有创造性。

我们对事实的认识取决于我们所处的地位和我们的观察习惯。

一个陌生的场面犹如婴儿眼中的世界,是“一种庞杂喧嚣的混乱状态”,就像另一个种族的所有成员在外国游客的眼中全都是一模一样的外国人。

在哥廷根曾召开过一次心理学会议,其间有一批据说是训练有素的观察家接受了一次饶有趣味的实验。

主办方预先安排了一场“事件”:突然,会议厅大门被人撞开,一个小丑冲了进来,一个持枪黑人在后面狂追。

他们在大厅中央停下厮打。

整个事件持续了不到20秒钟,“演员们”离开大厅。

会议主席要求在座各位当即写出一篇报告。

交上来的40篇报告中,关于主要事实的错误低于20%的只有1篇,有14篇的错误为20%-40%,有12篇达40%-50%,13篇高达50%以上。

When they heard the familiar “thump, thump” of their father’s car as it turned off the street and into the driveway, the children ran outside, zipped (快速移动) past their father and hurried into the back seat of the car.They were greeted by a familiar furry face and a wagging tail. Both face and tail belonged to Daisy, their three-year-old German shepherd. In the seat beside her lay her harness (背带). It was the symbol of Daisy and the children’s hard work. If all had gone well this afternoon, the harne ss would become Daisy’s work uniform, a sign to the world that she was a fully trained service dog.Every day for eighteen long months, Skyler and Kenny had trained Daisy to work with the visually impaired: people with sight problems or blindness. First, they trained her to perform the tasks that every obedient dog should know. Daisy learned to sit, to walk on a leash (皮带), and to settle patiently and wait. Those simple tasks came easily to their intelligent pup.But the more challenging tasks took time and patience. Daisy learned to move carefully around objects like signposts and trash cans. She needed to keep well clear of them in order to guide her owner along a safe path. Daisy learned to stop at the edge of a staircase, or any other spot that required a step up or down. A professional service dog trainer helped with the most challenging tasks. He taught Daisy to ignore orders that might put her owner in danger.Today, all of their hard work had come to a conclusion. Daisy had taken her service dog exam. But did she pass? Skyler and Kenny followed their father into the front hallway, with Daisy tagging close behind. They looked at their father expectantly. Their father gave a smile and a nod. The children ran off to tell their mother the news.4. What were the children waiting for by the door?A.A gift in the back seat.B.A dog they raised.C.A new car father bought.D.A familiar friend they missed.5. Why did Daisy take an exam?A.To better guide her owner.B.To show off her intelligence.C.To perform more challenging tasks.D.To get official recognition to provide service.6. Which of the following best describe Daisy’s 18-month training?A.Hard and dangerous.B.Easy and purposeful.C.Professional but challenging.D.Amusing but time-consuming.7. What was probably “the news”?A.Daisy would be trained again.B.Daisy would be free of harness.C.Daisy didn’t do well in the exam.D.Daisy became a qualified service dog.The Piraha are a primitive Amazonian tribe (部落) of hunter-gatherers who live deep in the Brazilian rainforest. The tribe has survived, their culture well-preserved, for centuries, although there are now only around 200 left. The Piraha, who communicate mainly through sounds and whistles, have fascinated scientists for years, mainly because they have almost no words for numbers. They use only three words to count one, two, and many.We know about the Piraha thanks to Professor Dan Everelt, who spent seven years with the tribe in the 70s and 80s. Everelt discovered a world without numbers, without time, without words for colors, without clauses and without a past tense. Their language, he found, was not just simple grammatically; it was limited in its range of sounds and differed between the sexes. For the men, it has just 11 speech sounds; for the women, it has only 10, the smallest number of speech sounds in the world. The language sounds more like humming than speech. The Piraha can also whistle their language, which is how men communicate when hunting.Their culture is similarly constrained. The Piraha can’t write, have little collective memory, and no concept of decorative art. In 1980 Everelt tried to teach them to count, he explained basic counting skills to an enthusiastic group fond of learning them to trade with other tribes. After eight months, not one could count to ten; even one plus one was beyond them. The experiment seemed to confirm Everelt’s theory: the tribe just couldn’t understand the concept of number.The Piraha’s inability to count is important because it seems to disprove Noam Chomsky’s influential Theory of Universal Grammar, which holds that the human mind has a natural ability for language, and that all languages share a basic rule structure, which enables children to understand abstract (抽象的) concepts such as number. One of Chomsky’s workmates has recently gone on an expedition (远征) to study the tribe. We do not yet know if the Piraha have persuaded him to change his theory.8. What’s the Piraha’s major attraction to researchers?A.A well-preserved lifestyle.B.A small existing population.C.A unique communicative way.D.An extremely simple counting system.9. What can we learn about the Piraha according to Everelt’ s findings?A.They use few speech sounds.B.Women speak less than men.C.Their grammar is complicated.D.They communicate only by whistling.10. What does the underlined word “constrained” mean in Paragraph 3?A.Strange B.Attractive C.Limited D.Respectable11. What can be inferred from the last paragraph?A.Findings about the Piraha help us know more about human mind.B.The Piraha’s inability to count challenges an existing theory of grammar.C.A researcher is making an exploration to study the Piraha’s counting ability.D.Languages have a similar structure so we can understand abstract concepts.Artificial cloud technology could soon be used in the fight against environmental damage. Researchers in Australia have used machines to spray salt water into the air, and noted that the reflective qualities of these artificial clouds helped protect the Great Barrier Reef from sun bleaching (漂白).The so-called cloud brightening project works by thickening existing clouds and reducing sunlight exposure to protect the reef. No artificial chemicals make it into the clouds in the sky. When water droplets steam, they leave only small salt crystals that float up into the atmosphere. This provides a larger surface area for water vapor to be liquids around them, forming thicker clouds.The past two years have seen uncommon forest fires and droughts triggered by the climate change emergency, meaning that widespread use of this technique may become more commonplace if carbon emissions are not checked.Drones, unmanned flying vehicles, have also entered the cloud controlling picture, used in the United Arab Emirates, a country desperately in need of more rainfall, to deliver electrical shocks to clouds in order to facilitate rainfall. Zapping (击打) clouds to produce a positive or negative charge within clouds can cause water droplets to form together. The greater the charge, the larger the droplets, which is vital for ensuring that as much rain as possible reaches the surface before steam gives off all the hard-won moisture (水分).Even if one waves aside climate change, global waterfall shortages are still an increasing concern, given the planet’s booming population. More people means more mouths to feed, and the demand for water in agriculture for animals and crops further increases urgency for cloud controlling technology. An increase in rain also leads to positive economic growth in many countries, as large harvests stabilize financial systems and living standards in all climates.Increasingly, scientists are looking to our skies in providing solutions to protect our environment. Cloud controlling technologies have promise. However, for this field of science to become practical economically, more research needs to be done in making this process a practicable option in protecting our environment.12. How does the cloud brightening project work?A.By creating more water vapor which later becomes liquids.B.By spraying chemicals and small salt crystals into the atmosphere.C.By expanding the water vapor arca and blocking more sunlight.D.By steaming water droplets to provide a larger surface area.13. What do we know about drones from paragraph 4?A.They spread larger water droplets.B.They charge clouds to promote rain.C.They will be popularized in dry years.D.They control the movements of clouds.14. What is paragraph 5 mainly about?A.Problems of overpopulation.B.Solutions to waterfall shortage.C.Urgency of economic development.D.Additional benefit of cloud technology.15. Which aspect does the author think should be improved?A.High cost.B.Research method.C.Environmental impact.D.Complicated process.From writing Shakespeare-style poetry to making music, ChatGPT has amazed the world since its launch in late 2022 by the US-based company Open AI. The AI program can answer questions on a whole host of topics, and write essays, stories and any other written texts you can think of. It does this by drawing on information collected from a large corpus (语料库) of text data.16 As Sam Altman, the CEO of Open AI, said in an interview with Forbes, “it’s not actually fundamentally new te chnology that made this (ChatGPT) have a moment.”One breakthrough behind today’s model is a network called Transformer, which was invented by Google researchers in 2017. 17 Transformer can therefore understand the meaning of texts more accurately with the help of the context.The GPT models built by Open AI combined Transformer with unguided learning. 18 ChatGPT can now generate human-like responses instantly due to the large scale of texts it learned from. “One of the biggest problems with ChatGPT is that it comes back, very confidently, with mistakes,” Michael Wooldridge at the Alan Turing Institute in London, UK, told The Guardian, “because it learns information from various resources. 19 So, at this point, ChatGPT doesn’t know the truth about the world, yet.”Some argue that ChatGPT will be used to generate fake news, spread misunderstanding, or be used for ill purposes. As for education, many US schools recently banned students from using ChatGPT on school networks since students began to use it as a shortcut for essays and research projects. 20One day last summer, my 9-year-old son Ben and I were riding the waves at a popular ocean beach on outer Cape Cod. As we were playing happily with our surfboard, I suddenly noticed an astonishing _________—some whales were spouting (喷水) well within view of where we _________.We stared and pointed in _________. “Ben, can you believe it?” I cried. “We’re swimming with the whales!” “Mom,” Ben said in reply, “we’re _________ swimming with the whales. This is their habitat, not ours!”Ben’s words took my breath away, more than the dramatic waves and the amazing sight of the _________.He was absolutely _________, of course. These whales live in the waters off Cape Cod. This is their _________—one that we visit, love and protect.

2020年庚子鼠年,十二生肖中为什么会有“鼠”这样让人望而生厌的动物,实在是一件很令人费解的事。

就中国文化来看,鼠从来都不是什么瑞兽,从《诗经》中的“硕鼠硕鼠,无食我黍”开始,鼠就一直是好逸恶劳的剥削者的象征,“三岁贯女”却“莫我肯顾”一直逼得百姓要“逝将去女,适彼乐土”。

《庄子》中吃“腐鼠”的“鸱”以“小鸟之心”度着“鹓鶵之度”历来嘲笑。

词典中关于“鼠”的成语几乎没有一个是好的,“抱头鼠窜、贼眉鼠眼、鼠目寸光……”鼠一直是如此的。

生活中比“鼠”名声好的动物实在是太多了,为什么中国人会把它放到十二生肖中?其实十二生肖中除了鼠,还有像虎,蛇这样的凶兽,这其实就是中国人的智慧,人世间除了也有千回百转,有春风得意也有时乖命蹇,一阴一阳之谓道,有苦有乐才是人生。

十二生肖代表着年份,年份代表着时间;十二生肖就是要告诉我们,顺和逆在年份中都是理所当然的事,我们当欣然接受。

而把“鼠”放在开头,再经历“虎”与“蛇”的挫折,最后回到“鸡豚狗彘之蓄”的安乐,由苦到乐先苦后甜。

在干支纪年中,十“天干”与年份尾数的数字相对,而“庚”恰好对应0,意味着只要天干为“庚”的年份,这一年份的尾数一定是0,0为“无”“无”为万物之始“无生万有”,而“鼠”为十二生肖的开头,因而,()“万事开头难”,面对新年伊始的挫折,我们只要心有信念百折不挠,就一定能够赢得更加美好的未来。

The natural history and cultural scenery of the area provide children with learning opportunities because they can enjoy the many wonders of this area.Fengjie Tiankeng Ground JointTiankeng Diqiao Scenic Area is located in the southern mountainous area of Fengjie County. The Tiankeng pit is 666 meters deep and is currently the deepest tiankeng in the world. The scenic spot is divided into ten areas including Xiaozhai Tiankeng, Tianjingxia Ground, Labyrinth River, and Longqiao River. There are many and weird karst cave shafts, and countless legends haunt them.Youyang Peach GardenYouyang Taohuayuan Scenic Area is a national forest park, a national 5A-level scenic spot, and a national outdoor sports training base. Located in the hinterland of Wuling Mountain. The Fuxi Cave in the scenic spot is about 3,000 meters long, with winding corridors, deep underground rivers, and color1 ful stalactites. The landscape is beautiful.Jinyun Mountain National Nature ReserveJinyun Mountain is located in Beibei District of Chongqing City, about 45 kilometers away from the Central District of Chongqing City. The nine peaks of Jinyun Mountain stand upright and rise from the ground. The ancient trees on the mountain are towering, the green bamboos form the forest, the environment is quiet, and the scenery is beautiful, so it is called "Little Emei". Among them, Yujian Peak is the highest, 1050 meters above sea level; Lion Peak is the most precipitous and spectacular, and the other peaks are also unique.Chongqing People's SquareChongqing's Great Hall of the People, one of the landmarks of Chongqing, gives people the deepest impression than its magnificent appearance resembling the Temple of Heaven. It also uses the traditional method of central axis symmetry, with colonnade-style double wings and a tower ending, plus a large green glazed roof, large red pillars, white railings, double-eave bucket arches, and painted carved beams.1.How deep is the Tiankeng Ground Joint?A.666mB.3,000mC.45kmD.1050m2.Which of the following rocks can you see in Youyang Peach Garden?A.LimestoneB.StalactiteC.MarbleD.Quartzite3.Which attraction is closest to downtown Chongqing?A.Fengjie Tiankeng Ground JointB.Jinyun Mountain National Nature ReserveC.Chongqing People's SquareD.Youyang Peach GardenBIdentifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to Make All the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, no name was mentioned.However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink. The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .Once the key ingredient had been identified, the researchers began to determine the dye’s molecularstructure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”4. The primary purpose of the study is to ________.A. restore and conserve ancient precious artworksB. determine the substance making up the foliumC. prove the ancient dye-making technique was organicD. identify which class of color1 folium belongs to5. The underlined phrase “poring over”in the second paragraph means ________.A. discussing publiclyB. testing repeatedlyC. passing directlyD. reading carefully6. What can be learned about the blue dye folium?A. It was essentially an inferior type of ink.B. It was the only kind made from wild berries.C. It could be carried and used easily.D. It was carefully squeezed from broken seeds.7. The article is mainly about _________.A. how the mystery ofa thousand-year-old blue dye was solvedB. why the researchers took the trouble to recreate the dyeC. what needs to be done to make an organic dye from a plantD. when and where the discovery of the dye was madeCZaki was small for his twelve years, and he was angry being treated as a child. Farid, his older brother, had been looked upon as a man long before he was Zaki’s age. Every day Farid and the other young Bahraini men went out in their wooden boats to dive for oysters (牡蛎). Many times Zaki begged to go along, but Faridalways refused to let him.So every day Zaki would go to the shallow water to practice. His grandfather, a former diver, would watch him and advise him. All morning, Zaki would practice diving beneath the waves. Every afternoon, again and again he would go underwater and hold his breath. With each day’s practice, his diving improved and he could hold hisbreath a little while longer. Soon Zaki felt as much at home in the water as he did out of it.Zaki rose early one day. He wanted to compete with his brother. They dived beneath the waves. Zaki opened his eyes and found himself looking into his brother’s face. Farid was smiling with confidence. Slowly, the smile was disappearing from Farid’s face. As more seconds passed, a worried look appeared on Farid’s face. Farid was realizing that Zaki could possibly beat him. Looking into Farid’s eyes, Zaki suddenly understood what losing could mean to his brother. Never would the villagers allow him to live it down. He would be laughed at by losing to a little child. Almost without thinking, Zaki kicked his feet and rose to the surface of the water a second before Farid’s head appeared beside him.The men around them cheered and patted Farid on the back. Farid, however, put his arm around Zaki’s shoulders. “Today,” Farid announced, “we shall have a new diver among us.” Then quietly, for Zaki’s ears alone, he said “Thank you, my brother.” And Zaki knew that they both had learned that it takes more than strength to makea man.8. What is the second paragraph mainly about?A. Zaki’s grandfather was a good diver.B. Zaki liked staying at home every day.C. Zaki practised hard in the water daily.D. Zaki’s grandfather encouraged him to dive.9. Which of the following best describes Zaki according to paragraph 3?A. Considerate.B. Ambitious.C. Confident.D. Adventurous.10. What can we infer from the last sentence of the text?A. Farid beat his little brother easily.B. Zaki was as strong as his brother.C. Zaki regretted losing the competition.D. Both Farid and Zaki had grown up.11. What is the best title for the text?A. Farid’s PrideB. Zaki’s ChallengeC. Brothers’ CompetitionD. Grandfather’s AdviceDMany Americans experience surprise (or disappointment) when they wake up on Christmas Day. They mightbe surprised or disappointed by a family member’s actions. They might be happy or unhappy about a Christmas gift. Imagine a child expects to get an Xbox or PlayStation for Christmas. On Christmas morning, they quickly open their gift. Inside is an English grammar book. They might feel disappointed. The Everyday Grammar team would prefer the new English grammar book. But if you are like most young people, you would probably rather have a new video game.Today, we are going to explore those feelings-feelings of surprise and disappointment. In other words, we are going to explore how speakers show that reality was better or worse than their expectations.Many languages use words to express expectation. Speakers also use words to express how events are not happening as expected. This idea is known as “counter expectation”.Do not worry about the term. Just remember that it means that speakers use words to show that reality is countering their expectations.English has many words that serve this purpose. Three of the most common are the words “even”, “still” and “actually”. You will often hear them in informal, everyday speech. Speakers use these words to show disappointment. The pitch of their voice tells you what they mean. Let’s study examples of each word.Speakers often use the word "even” to show disappointment or surprise. Imagine a young child that expects a phone call from a family member-perhaps an uncle or grandparent. The phone call never comes. The child might say the following: “What’s wrong with him? He didn’t even call me on Christmas day.” Americans sometimes use “still” for showing how reality does not quite meet their expectations: “You’re still here? It’s over! Go home. Go!” Another common word that shows surprise or disappointment is “actually”: “I can’t believe it! Uncle Bob actually stole her Christmas gift.”12. What might most young Americans prefer as a Christmas gift according to paragraph 1?A. A newly made video game.B. An English grammar book.C. A new designed school bag.D. A unique jacket from their parents.13. What does the underlined phrase “counter expectation” in paragraph 3 mean?A. Expression of disappointment.B. Something expected to happen.C. The same with one’s expectation.D. A result against what is expected.14. What do the three words “even”, “still” and “actually” have in common?A. They are easy to understand.B. They express disappointment.C. They show delighted feelings.D. They are used most at Christmas.15. What’s the last paragraph mainly about?A. Expectations from loved ones.B. Different uses of the three words.C. Examples of the use of the three words.D. Emotions of disappointment and surprise.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

When the government was 2 , the situation in Cambodia got worse. Many people were killed, while others were forced into hard labor. Sometimes entire families were wiped out.Siv had 3 to leave Cambodia before the anti-government army took over the country. Unfortunately, he was 4 . As a result, he and his family were 5 from their homes and forced to labor in rice fields. After a while, Siv managed to escape.

Soon he was on his way to the states.After graduating from Columbia University, Siv was offered a job in the White House working for President Reagan's closest advisors.

Studies show that Egyptians were involved in grape and wine production. Also, the early Romans were known to have developed many grape varieties.Grapes 16 (grow) in California for more than 200 years. The tradition of viticulture (growing grapes) began in 1769 17 the Spanish started building churches throughout California. Then the boom in grapes planted for eating arose in 18 early 1800s. William Wolfskill, 19 (found) of California's citrus (柑橘类的植物) industry, planted the first table grape vineyard in 1839 near Los Angeles.20 the 1850s, the United States had officially acquired California from Mexico,21 80,000 gold seekers had moved to the region. A few of 22 had the foresight to realize 23 there was money in grapes as well as in gold.Today California wine, table grapes, and raisins are all important agricultural products, with approximately 700,000 acres 24 (plant) in vineyards. About 85% of California's table grape production is in the southern San Joaquin Valley region, with the Coachella Valley region accounting for most of the 25 (remain) production.第二部分:阅读(共两节,满分50分)第一节阅读理解(共20小题;每小题2分,满分40分)A.Brittnie Pemberton listened attentively as Jim Herrick took her and her mother, Tanya, on a brief tour of San Diego State University on Thursday. Her dream is much closer to reality after she received a promise from the university. The university promised that she would get a full four-year scholarship to the school as long as she met the entrance requirements.Brittnie, 10, laughed. Her mom cried.They live at the Salvation Army Door of Hope, a living center for homeless women and their children. Photojournalist Linda Solomon met them in August when she came to the facility and taught boys and girls, ages three-and-a-half to 13, how to take pictures. She gave them all disposable cameras and told them to capture images that reflected their dreams. The children's images—a big house, a church, a playground, a backyard and more—are kept.This is a project called ―Pictures of Hope" organized by the Salvation Army."I wish to go to college, so I took a picture of the sign out in front of San Diego State University," Brittnie said last month. The Fletcher Elementary School fifth-grader was pointing to the Christmas card bearing her photograph.Adrienne Finley, development director at the Salvation Army, hosted a reception for Solomon, who told Finley about the president of a small university who gave a child the scholarship she dreamed of last year.Finley called his old friend, Herrick, who serves as the SDSU President. "We have a wonderful opportunity here to make a difference in a little girl's life," Finley said. Soon her mom and Brittnie were face to face with SDSU President Jim Herrick."Y ou must be Brittnie," he said, reaching out to shake her hand. She quickly pulled her hands out of the pockets of the new SDSU sweatshirt she had been given that morning.They sat down at a table in his office and talked about college, about science, about her love of math and his hope that she and other girls wouldn't lose interest in those subjects, as happens to many girls as they grow older.Then they talked about how much discipline she would need over the next eight years to make her dream come true. Both signed the paper outlining their agreement to the terms of the scholarship. Back outside on the sunny campus, Brittnie admitted she was tempted sometimes not to do her homework. "But not anymore," she said.26. According to the first paragraph, we can know that ________.A. Jim Herrick told Brittnie the good news that she had been admitted to SDSUB. Brittnie will not need to pay for her university education if she was accepted by SDSUC. Jim Herrick promised Tanya she didn’t have to pay for her daughter’s college educationD. Tanya knew that Brittnie had little chance of meeting the entrance requirements27. The Salvation Army Door of Hope is intended to ________.A. help young women and their children get higher educationB. provide shelters for homeless women and their childrenC. educate homeless moms so they can provide for their childrenD. cheer up children who are both fatherless and homeless28. According to the passage, the following statements are true EXCEPT ________.A. Linda Solomon taught children photography to inspire them.B. Children told people about their dreams through their pictures.C. Brittnie took a picture standing at the gate of SDSU.D. Brittnie’s picture was so good that it was printed on a Christmas card.29. From the conversation between Ferrick and Brittnie, we can infer that ________.A. Ferrick has a strong belief that Brittnie will be a scientist in the future.B. Brittnie, as well as some other girls, is interested in both science and math.C. some girls would not be so good in science and math as boys as they grow older.D. Brittnie will never lose interest in science because of her deep love.30. Which of the following words can best describe Brittnie’s feelings when she signed theagreement about the scholarship?A. Encouraged.B. Calm.C. Nervous.D. Proud.B.Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力)of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled —they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Old er children often identified the smaller circle as the larger one, and adults got it wrong most of the time.As children get older, Doherty said, their brains may develop the ability to identify visual (视觉的)context (上下文). In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.31. Doherty and his team of scientists did an experiment to evaluate ________.A.children’s and adults’ eye-sight B.people’s ability to see accuratelyC.children’s and adults’ brains D.the influence of people’s age32. When asked to find the larger circle, ________.A.children at 6 got it wrong 79 % of the time with no gray ones aroundB.only adults over 18 got it right 95% of the time with gray ones aroundC.children at 4 got it right about 79 % of the time with gray ones aroundD.adults got it right most of the time with gray ones around33. According to the passage, we can know that ________.A.a smaller orange circle appears bigger on a white backgroundB.an orange circle appears bigger than a gray one of the same sizeC.a circle surrounded by other circles looks bigger than its real sizeD.a circle surrounded by bigger ones looks smaller than its real size34. V isual context may work when children get older than ________.A.4 B.6 C.10 D.1835. Why are younger children not fooled?A.Because they are smarter than older children and adults.B.Because older people are influenced by their experience.C.Because people’s eyes become weaker as they grow older.D.Because their brain can hardly notice related things together.C.Riding through the royal forest of Sherwood on a wonderful May morning, you don't have a care in the world. Then you hear a bird call, the faint rustling of trees, and suddenly a man armed with a longbow appears in your path.He wears a feathered cap. Y ou can't see the man's face clearly, but you don't have to. He is dressed in Lincoln green, the color of Robin Hood -- the most famous English outlaw of all time.Don't worry; he won't harm you -- not yet, anyway. He'll invite you to join him and his outlaw band for a feast. The meal of choice? V enison -- freshly-killed deer. Only a king is allowed to hunt it, but then Robin never did worry about the law.After your feast, Robin, or his faithful lieutenant Little John, will ask you a question. How much money are you carrying? If you answer truthfully, you may keep all that you have. If you need money, then Robin will give or lend you some. But if you lie to him -- if you hoard your money, well ... you won't have that money for very long. Y ou'll be stripped of your clothes and cash, tied backwards on your horse and sent back to Nottingham in shame. And your money? It will go to help someone in need.Most people love Robin Hood. And that's a good thing. Just as common people are allowed to hunt harmful wolves, anyone can hunt Robin Hood. The sheriff would pay for Robin's capture just as surely as he would pay for a wolf's head. Robin and his band are often called wolfsheads by their enemies.Robin Hood is an outlaw. That means he lives outside the protection of the law. But Robin is a law unto himself. He's the self-styled king of the greenwood -- either Sherwood Forest in Nottinghamshire or Barnsdale in Y orkshire.Robin is no common criminal. As the famous saying goes, he robs from the rich and gives to the poor. The poor have little to fear from Robin Hood. His enemies are the rich and corrupt, especially the Sheriff of Nottingham and the bad apples in the Church like the Abbot of St. Mary's and the Bishop of Hereford.Robin defends the underdog against oppression.36. Which of the following is NOT a usual practice of Robin Hood and his band?A. Hunting deer and serving their guests with their meat as dinner.B. Hunting harmful wolves and cutting their heads for money.C. Robbing the dishonest rich people out of their money and clothes.D. Protecting and giving money to the low life in need of help.37. The underlined wo rd ―hoard‖ in paragraph 4 is closest in meaning to _______.A. give awayB. hide awayC. give upD. save up38. Why are Robin Hood and his band called wolfsheads?A. They are as fierce as wolves when they robbed people.B. They are as harmful as wolfs and should be hunted.C. They sometimes put on masks of wolfsheads to scare people.D. They are as valuable as wolfsheads because both will bring money if caught.39. Which of the following people is NOT an enemy of Robin Hood?A. The King of England.B. The Sheriff of Nottingham.C. Little John.D. The Bishop of Hereford.40. The purpose of the passage is ____.A. to warn people of the danger of traveling through the forest of SherwoodB. to introduce to you the self-styled king of the greenwood—Robin HoodC. to advise people to be honest with Robin Hood when he questions youD. to describe the fights between Robin Hood and his enemiesD.AFTER years of political point-scoring over their rightful home, more than 30 of the historic Lewis chessmen go on show in Edinburgh today in an exhibition expected to draw tens of thousands of visitors.―The Lewis Chessmen: Unmasked‖ runs for four months at the National Museum of Scotland. It shows 23 Lewis chess pieces and other artifacts from the British Museum –the first loan of any chessmen to Edinburgh in 14 years –alongside all 11 pieces in Scotland’s own collection.Gordon Rintoul, director of National Museums Scotland (NMS), said, ―These objects have a speci al place in the public imagination … we are delighted to be opening the exhibition in partnership with the British Museum.‖The exhibition also reflects new Scottish research questioning long-held assumptions about when the chessmen were made, who owned them, how they were used, and where they were found on Lewis.The traditional story of the chessmen tells that they were found in sand dunes(沙丘) at Uig on Lewis in 1831. They were made in Scandinavia in the 12th century; it was assumed, and probably abandoned by a passing merchant.Dr. Caldwell and others now suggest they were actually found several miles south, and hope further study could confirm that view. The exhibition says it is possible that one of several historical figures on Lewis might have collected and owned them – possibly Olaf, the younger brother of a King of the Isles, or a local bishop.While it is still widely thought they were made in Trondheim, Norway, close analysis of some carvings now point to a later date. Three of the bishops, for example, wear miters, their traditional hats, in styles thought to date from after 1300, a century later than previously thought.When First Minister Alex Salmond took power in 2007, he called for the return of some 90 Lewis pieces bought by the British Museum in the 19th century. His former cultural minister, Linda Fabiani, said division of the set was ―unacceptable‖.But the British Museum and the UK government has stood firm, and that appears unlikely to change.While some Liberal Democrats(自由民主党员)have supported moves to return cultural artifacts to their countries of origin, the new UK minister of culture is a Conservative, Jeremy Hunt.41. What will be shown in the exhibition called ―The Lewis Chessmen: Unmasked‖?A. More than 30 Lewis chessmen owned by the National Museum of Scotland.B. 23 Lewis chessmen and other artifacts owned by the British Museum.C. 11 Lewis chessmen owned by Edinburgh, Scotland.D. More than 30 Lewis chessmen and other artifacts owned by the UK.42. Which of the following findings about the Lewis chessmen has already been confirmed?A. They were found in sand dunes at Uig on Lewis.B. They were abandoned by a passing merchant.C. Olaf, the younger brother of a King of the Isles, collected and owned them.D. Some of them were made much later than the 12th century.43. By saying ―division of the set was “unacceptable”‖, Linda Fabiani probably meant that____.A. the British Museum should keep the Lewis chessmen they hadB. the Lewis chessmen should be given back and put together with the othersC. the Lewis chessmen should not be shown separatelyD. the British Museum shouldn’t have bought the 90 Lewis chessmen44. Which of the following people strongly supports the return of the Lewis chessmen toNorway?A. Gordon RintoulB. Dr CaldwellC. Alex SalmondD. Jeremy Hunt45. The purpose of the passage is to ____.A. attract people to the exhibition called ―The Lewis Chessmen: Unmasked‖B. show findings about the history of the Lewis chessmenC. accuse the British government for refusing to return the Lewis chessmenD. introduce the Lewis chessmen and arguments about their rightful home第二节:信息匹配(共5小题;每小题2分,满分10分)阅读下列应用文及相关信息,并按照要求匹配信息。
