2008~2009学年第一学期期末考试试卷(G卷)【模板】

2008~2009学年第一学期期末考试试卷(G卷)请在下列材料分析题中任选二题(每题50分)材料分析题之一——飘扬的灵魂2004年6月20日,马骅在明永冰川景区公路距澜沧江桥300米处遭遇车祸,被抛入滔滔江水中,永远离开了我们。

在不熟悉的人看来,马骅给人的印象有些颓废,长发,一副睡不醒的样子。

但在狂放的外表下他其实极为善于待人接物。

他天生记忆力惊人,最爱玩的一个游戏就是拿本书给朋友,要对方考他某段文字在第几页,结果往往百不失一。

也因为这个特长,马骅博览群书,涉猎广泛。

浪漫热情是他的本真的天性。

毕业后,马骅去了一家外企——韩国衣恋集团,并很快升任总经理助理。

即使是在今天,成为一名外企高管仍然是大多数**大学生实现自己人生价值的主流途径,然而马骅却视之如敝履。

两年以后,他辞去工作。

在马骅身上,凝聚着知识者的激情、浪漫和不羁的游戏精神。

他不愿在一个地方待上太久,因为他无法忍受沉闷、刻板的庸常生活。

所以他总是幻想远方,幻想别处,渴望一个人的自由,并且身体力行。

辞职以后,马骅在厦门呆了一段时间,然而离开,到北京,回家乡天津,之后又到了北京,并跟朋友成立了“偶”戏剧工作室。

去云南之前,马骅作了近一年时间的准备。

2003年的一天,明永村村长大扎西第一次见到了马骅,就发现他是一个非常了解藏文化的人,一个非常不错的小伙子。

不久以后,朋友们陆续接到了他的“雪山来信”的文字。

在“雪山来信”中,马骅写了他身边世界的美丽:雪水化下的溪流,粉红的桃花,蓝汪汪的江水,粉红色的碗口大小的高山杜鹃,原始森林覆盖的山峰,一米多厚的积雪上黑色飞鼠的尸体……他也写了生活的艰苦:用粪水浇地种菜,两个星期一次的热水澡,把发臭的肉吃出火腿的味道,每天为了挣50元钱而爬10个小时的山……他的到来让这个梅里雪山脚下的村子有了不一样的变化。

他开始教学生们说普通话,告诉他们保护生态环境的重要性,周末他带着学生拿着大口袋去捡垃圾,教他们打篮球,由于来明永村旅游的外国人比较多,他又自办了一所夜校,教村民说英语。

Oh!There were so many people ! I had to wait in the rain.My hair didn't get wet because I wore a hat.But my clothes did.When at last it was my turn, I filled all the bottles as quickly as possible.I began making my way back to school when I saw a boy coming towards me.He was holding two umbrellas.He shouted hello and as he came nearer, I recognized that he was Xiao Bai.Xiao Bai had been my classmate for nearly three years but we never shared more than ten sentences.He was silent but I liked talking.We were quite different people and had nothing in common.I didn't like him and didn't even want to see him.“Hey! What's wrong?”His words brought me out of my thoughts.“I saw you standing in the rain so I brought you this umbrella.But it seems a little late, your clothes are already wet.”On hearing this, I was so moved that I couldn't say a single word.“Don't just stand there, let's go!”Xiao Bai said and held the umbrella for me.We walked towards the classroom and this time, we talked a lot.“I know you don't like me.But I want to make friends with you,”he said.“Y ou may think I'm silent, but it is because I can't find the right words to say.”This was quite a different Xiao Bai.The rain finally stopped and we saw a rainbow(彩虹)in the blue sky.I took a deep breath and said to myself:“It is a big mistake to judge someone only by his appearance(外表).And a friend in need is a friend indeed.”31.On the way to the water room, the writer_________.A.didn't know he had to wait for a long time to get waterB.felt worried because he had to wait for a long timeC.bought a hat and wore itD.was unhappy because it was raining32.The writer seldom talked to Xiao Bai because_________.A.he thought they were different kinds of personsB.he worked hard at his lessonsC.they were not friendly to each other D.Xiao Bai once hurt him 33.The writer wrote the passage to tell us that _________.A.he has made a new friendB.we can't judge a person only by his appearanceC.the water room in his school is too small D.he likes talkingBHONG KONG—The visiting Chinese gold medal winners displayed(展示)their superb sports skills again in Hong Kong on Saturday morming, whose performance impressed over 5,000 Hong Kong spectators(观众)face to face as well as tens of thousands of viewers through TV live broadcasts.The enthusiasm(热情)for the Olympic Games was rekindled(重新点燃)in Hong Kong as Chinese mainland's Olympic gold medal winners on Saturday made their appearances and met the public.As part of their visit to Hong Kong, they put on demonstrations(示范)of table tennis, badminton, diving and gymnastics.More than 5,000 people watched their performance, while tens of thousands of viewers watched the TV live broadcasts at home or elsewhere.The gold medal winners also had exchanges with young Hang Kongathletes.Some of them took part in the sports-for-fun activities with the gold medal winners in table tennis, badminton and gymnastics.China's Olympic gold medal winners arrived in Hong Kong on Friday, starting their three-day visit to the city.―I hope the Hong Kong public can use this opportunity to share the joy and pride of their country,‖ Hong Kong Special Administrative Region's Chief Executive Donald Tsang said.All the 63 gold medal winners from the Beijing Olympic Games took part in the flag-raising ceremony at the Golden Bauhinia Square on Saturday morning.After the sports demonstration, they met the public at a Gala Show at the Hong Kong Stadium on Saturday afternoon.The gold medal winners will leave for Macao on Sunday afternoon after visiting Disneyland and the Ocean Park, two of Hong Kong's famous theme parks.34.We learn from the text that ________.A.Chinese mainland's Olympic gold medal winners stayed in HK for three days B.5,000 people watched the TV live broadcasts at home or elsewhereC.China's Olympic gold medal winners left Hang Kong on FridayD.some gold medal winners took part in the flag-raising ceremony at the Golden Bauhinia Square35.The underlined word ― superb‖(Paragraph One)probably means ―_______‖.A.strange B.simple C.excellent D.complex 36.Which of the following is NOT the one that Chinese mainland's Olymp ic gold medal winners put on demonstrations?A.Gymnastics.B.Badminton.C.Table tennis.D.Tennis.37. Which city will the Chinese mainland's Olympic gold medal winners visit next?A.Guangzhou.B.Macao.C.Shanghai.D.Tianjin.CMeals at the family dinner table could be the key to stopping teenage girls from developing eating disorders(紊乱).New research shows girls who often have family meals are much less likely to have extreme(极端的)weight control behaviours.A study of more than 2,500 American high school students found that girls who ate five or more family meals a week had a much healthier relationship with food in later life.The research, published in Archives of Pediatrics and Adolescent Medicine, interviewed students aged 13 to 17 in 1999 who were followed up five years later.Regular family meals were found to have a good effect no matter what the girl's age, weight, or relationship with her family are.Experts say doctors should encourage families to have dinner at the table instead of on the couch in front of the television to protect against serious eating disorders such as anorexia.Belinda Dalton, director of eating disorders clinic The Oak House, said eating with family helped bring young people's relationship with food back to normal.An eating disorders expert, Kirsty Greenwood, said meal times were oftendifficult for sufferers.―They feel very ashamed(羞愧的)of their eating habits and often won't eat with other people.Perhaps it's because they haven't experienced the importance of the family meal in their growing up,‖ she said.The study found having family meals made no difference to the future eating habits of boys.38.We learn from the text that ________.A.family meals were found to have a good effect on boysB.doctors should encourage families to have dinner on the couchC.eating with family couldn't help bring young people's relationship with food back to normalD.having family meals is very necessary to girls39.The underl ined word ―anorexia‖(Paragraph Five)here probably means―___‖.A.loss of the wish to eat B.family mealC.strong wish to eat D.weight control behaviour 40.According to the text, Archives of Pediatrics and Adolescent Medicine (Paragraph Four)is probably the name of________.A.a film B.a magazine C.a TV play D.a history book 41.According to the text, what is the difficult moment for the eating disorders sufferers?A.

请你们:
(1)建立数学模型和算法以确定靶标上圆的圆心在该相机像平面的像坐标,这里坐标系原点取在该相机的光学中心,x-y平面平行于像平面;
六、非客观题(本大题10分)图示对称三相电路中,已知星形联接负载阻抗 ,在220V相电压下,求电路的线电压Ul,线电流Il,相电流Ip和有功功率P。若把电路接成三角形连接,有功功率P为多少?
七、非客观题(本大题10分)串联谐振电路中已知电容C=0.25F、电感L=40mH。求当电阻:(1)R=10,(2)R=100时,该电路的谐振角频率 ,品质因数Q和通频带 ,比较这三个量都和哪些因素有关。
解:求开路电压:
求等效电阻: 得到:
六、非客观题(本大题10分)图示对称三相电路中,已知星形联接负载(复)阻抗,若已测得电路无功功率Q=500var,求电路有功功率P。
解: 得到:
电路有功功率:
七、非客观题(本大题10分)求图示正弦交流电路的有功功率P和无功功率Q。
解:
总电流:
八、非客观题(本大题10分)电路如图所示,开关闭合后,电容电压的全响应。
标定的一种做法是:在一块平板上画若干个点,同时用这两部相机照相,分别得到这些点在它们像平面上的像点,利用这两组像点的几何关系就可以得到这两部相机的相对位置。然而,无论在物平面或像平面上我们都无法直接得到没有几何尺寸的“点”。实际的做法是在物平面上画若干个圆(称为靶标),它们的圆心就是几何的点了。而它们的像一般会变形,如图1所示,所以必须从靶标上的这些圆的像中把圆心的像精确地找到,标定就可实现。图1靶标上圆的像
