二、论述题:(20 分)
举例论述课程《电磁学》和《电动力学》的共同与不同之处,举例说明经典电动力学的局限性。 要求观点清晰明确。 解: (1)课程《电磁学》和《电动力学》的共同之处在于都是研究电磁现象与电磁相互作用。不 同之处在于:《电磁学》侧重应用积分公式描述基本电磁现象,而《电动力学》侧重应用微分 公式分析电磁现象规律。前者是基础,后者是深化。 (2)经典电动力学的局限性
原子处于基态时是稳定的不会产生辐射,这点是和经典理论有深刻矛盾的 . 按照经典理 论,电子在原子核电场作用下运动,由于有加速度,必然向外辐射电磁波,因而电子运动的能 量亦逐渐衰减,最后电子会掉到原子核内,因而根本不存在稳定的原子.这结论是和客观事实 完全矛盾的.只有用量子理论才能解释基态的稳定性.

Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A, B, C, and D. You should decide on the best choice andmark the corresponding letter on the Answer Sheet.Questions 21 to 25 are based on the following passage:The struggle against malnutrition (营养不良) and hunger is as old as man himself, and never across the face of our planet has the outcome been more in doubt. Malnutrition afflicts (折磨) an estimated 400 million to 1.5 billion of the world’s poor. Even in the affluent U.S., poverty means undernourishment for an estimated ten to twenty million. Hardest hit are children, whose growing bodies demand two and a half times more protein, than those of adults. Nutrition experts estimate that 70 percent of the children in low-income countries are affected.Misshapen bodies tell the tragic story of malnutrition. Medical science identifies two major types of malnutrition which usually occur in combination. The first, kwashiorkor, is typified by the bloated(肿胀的)look, the opposite of what we associate with starvation. Accumulated fluids pushing against wasted muscles account for the plumpness of hands, feet, belly and face. Caused by an acute lack of protein, kwashiorkor can bring brain damage, irritability, loss of appetite and so on.On the other hand, stick limbs, a bloated belly, wide eyes, and the stretched-skin face of an old person mark victims of marasmus, a word taken from the Greek “to waste away”. Lacking calories as well as protein, sufferers may weigh only half as much as normal. With fat gone, the skin hangs in wrinkles or draws tight over bones. Children, those growing bodies require large amounts of protein, are afflicted in greatest numbers, but perhaps only three percent of all child victims suffer the extreme stages described.Scientists are working hard to develop new weapons against malnutrition and starvation. But two thirds of the human population of 3.9 billion live in the poorest countries which also have the highest birth rates. Thus, of the 74 million people added to the population each year, four out of five will be born in a have-not country---a country unable to supply its people’s nutritional needs.21. Malnutrition is ___________.C. more serious than beforeD. inclined to be less serious22. The phrase “waste away” (Line 2, Para.3) means____________.A. become thinnerB. loseC. misshapeD. under-nourish23. Which of the following statements is NOT mentioned in the passage?A. The majority of children suffer the most serious stages of marasmus.B. Malnutrition has afflicted millions of people all over the world.C. Both types of malnutrition are caused by lack of protein.D. The struggle against malnutrition has a long history.24. It can be inferred from the passage that the struggle against malnutrition is_____.A. certain to succeedB. likely to succeedC. certain to failD. hard to succeed25. All the conclusions the writer makes are correct EXCEPT ________.A. Malnutrition is a serious global problem.B. The high rate of population growth is irresponsible for malnutrition.C. Scientists are working hard to cope with the food problem.D. Children suffer most because they need more protein than adults.Questions 26 to 27 are based on the following passage:One of the most exciting attempts to find the source of the Mississippi was made by the Italian Constantino Beltrami. Aged 41, in Italy he had been a magistrate (地⽅法官) and student of the classic. In the New World, however, he was interested in exploration—not so much for reasons of scientific curiosity but in response to romantic dreams nourished by literary and mythological study. Setting out from St. Louis in 1823, he traveled as far as Fort Snelling by boat and then proceeded up river by canoe, accompanied by three Indians. The journey was an adventurous one. On August 23, 1823, Beltrami came to a small lake in what is now northern Minnesota, which he called Lake Julia in memory of a woman he had loved, and which he proclaimed to be the source of the Mississippi. His romantic self-comparison to Icarus, the Phoenicians, Marco Polo and Columbus, however, was not calculated to satisfy geographers, for he had no compass with which to determine his location. When he returned to New Orleans, he related his travels and as a result, he was welcomed in Europe and became a member of several academies, while Lafayette and Chateaubriand honored him with their friendship. In America, on the other hand, many regarded him as an imposter(冒名顶替的⼈).Nine years after Beltrami, Henry Rowe Schoolcraft, the United States Superintendent(负责⼈) of Indian Affairs proclaimed “Itasca”--- a lake in Minnesota—the true source of the Mississippi.His claim that Lake Itasca was the source of the Mississippi was accepted for many years, but many geologists now disagree. Accurate recent surveys show that a spring flows into it from Elk Lake, and that this in turn is linked with yet other lakes, which may be collectively regarded as the source of the great river.B.he was very curious about the worldC.he wanted to make his dreams come trueD.he was fascinated by scientific discoveries27.T he word “relate” (Line 11, Para. 1) means___________.A. connectB. compareC. tellD. contrast28. Which of the following statements is true?A. He received warm welcome in America.B. Lake Itasca was undoubtedly the source of the Mississippi.C. Beltrami wasn’t a profe ssional explorer.D. Beltrami wanted to find the source of the Mississippi single-handed.29. Which of the following persons has been mentioned as explorers in the passage?A. LafayetteB. Henry Rowe SchoolcraftC. ChateaubriandD. the Phoenicians30. What’s the best title of the passage?A. The Source of the Mississippi.B. The History of the Mississippi.C. The Mystery of the Mississippi.D. The Description of the Mississippi.Questions 31 to 35 are based on the following passage:Every second, one hectare of the world’s rainforest is destroyed. That’s equivalent to two football fields. An area the size of New York City is lost every day. In a year, that adds up to 31 million hectares—more than the land area of Poland. This alarming rate of destruction has serious consequences for the environment; scientists estimate, for example, that 137 species of plant, insect or animal become extinct every day due to logging (砍伐). In British Columbia, where, since 1990, 13 rainforest valleys have been clear cut, 142 species of salmon have already become extinct, and the habitats of grizzly(灰的) bears, wolves and many other creatures are threatened. Logging, however, provides jobs, profits, taxes for the government and cheap products of all kinds for consumers, so the government is reluctant to restrict or control it.Much of Canadian forestry production goes towards making pulp(纸浆) and paper. According to the Canadian Pulp and Paper Association, Canada supplies 34% of the world’s wood pulp and 49% of its newsprint paper. If these paper products could be produced in some other way, Canadian forests could be preserved. Recently, a possible alternative way of producing paper has been suggested by agriculturalists and environmentalists: a plant called hemp(⼤⿇).Hemp has been cultivated by many cultures for thousands of years. It produces fibre which can be made into paper, fuel, oils, textiles, food, and rope. For many centuries, it was essential to the economies of many countries because it was used to make the ropes and cables used on sailing ships; colonial expansion and the establishment of a world-wide trading network would not have been possible without hemp. Nowadays, ships’ cables are usually made from wire or synthetic fibers, but31. How long does it take for 300 hectares of rainforest to be destroyed?A. One minute.B. Two minutes.C. Three minutes.D. Five minutes.32. The following are the reasons why logging is hard to control EXCEPT that ______.A. it provides taxes for the countryB. it offers extra jobsC. it supplies people with cheap productsD. it leads to the erosion of the land33. Why is pulp and paper production important in Canada?A. Because it plays a vital role in Canada’s economy.B. Because it provides many jobs for Canadians.C. Because it enjoys a long history in Canada.D. Because it helps produce newspapers and magazines.34. Hemp was essential to many countries in the past because ________.A. sailors needed it for foodB. ropes on ships were made from itC. ships used it as fuelD. it was exported to many other countries35. The advantage of hemp in paper production over trees is ________.A. higher qualityB. more outputC. cleaner environmentD. cheaper laborPart III Vocabulary (20%)Directions:There are 40 incomplete sentences in this part. For each sentence there are four choices marked A, B, C and D. Choose the ONE answer that best completes the sentence. Then mark the corresponding letter on the Answer Sheet. 36.We have to _______ that if it is wrong to injure humans it must also be wrong to do theidentical or very similar injury to non-humans.A.concedeB. confuseC. consentD. concealD. determinant38.Some studies confirmed that this kind of disease was ______ in tropical countries.A. flourishingB. prevalentC. frustratingD. irresistible39.It is a wise _________ to lock your doors when you leave your house.A. precautionB. predictionC. approachD. dilemma40.Their demand has not the slightest ________ of being met.A. prospectB. perspectiveC. perceptionD. predominance41.Just as a book is often judged _____ by the quality and appearance of its cover, a person is judged immediately by his appearance.A. initiallyB. presumablyC. incrediblyD. drastically42.A man with confidence will state his opinions in an/a ________ tone of voice.A. criticalB. assertiveC. aspiringD. arrogant43.It is a/an ________ trick to hide a boy’s book so that he gets into trouble for losing it.A. ingeniousB. meanC. justifiedC. liabilityD. sincerity45.I’m sure she’ll be able to ______ the role though it is demanding.A. cut down onB. get a handle onC. carry offD. put a guilt trip on46.Nuclear weapons should be used only as a last ______.A. resortB. appealC. solutionD. approach47.The man, once penniless, never dreamed that he would _______ owing such a lot of property.A. wind upB. build upC. back upD. pile up48.The less you rely on painkillers now, the better it will be for your health ______ .A. on that accountB. on the groundsC. in the long runD. on the spot49.A well-written composition ________ good choice of words and clear organization among other things.A. abides byB. caters toC. points toD. calls for50.A specialized journal may have a small _______ compared with a newspaper, but it is of particular importance to those who use it.A. coverageD. implementation51.Although the original idea was good, its _______ has produced a disappointing result.A. reproductionB. penetrationC. reservationD. execution52.You can’t rely on his promise.

4、简要回答产生玻璃化现象的原因。

答:1)激素浓度细胞分裂素浓度过大;生长素和细胞分裂素比例不适合。

2)温度温度过高;温度变化幅度大。

3)湿度湿度过大。

4)培养基的硬度培养基过软,水分含量过高。

5)光照光照弱,玻璃化比例增加。

6)培养基成分一般认为提高培养基中的碳氮比,可以减少玻璃化的比例。

7)通风条件
5、简要回答污染产生的原因。

答:1)培养基及各种使用器具消毒不彻底。

2)外植体灭菌时不彻底,有菌残存在细胞组织中。

3)操作时人为因素带入。

4)环境不清洁。

5)超净工作区域污染。

五、论述题(10×2,20分)
1、请论述蝴蝶兰的组织培养及其驯化移栽过程。

一、无菌培养的建立
1、培养部位
蝴蝶兰的茎尖、茎段、叶片、花梗腋芽、花梗节间、根尖等各部位均可用作外植体,用花梗腋芽或花梗节间作外植体成功率高,是合适的取样部位。

2、培养方法
1)花梗腋芽的培养
蝴蝶兰为总状花序,近顶端的节着生花蕾,近基部的几个节,常具有苞叶覆盖的腋芽。

剪取整枝花梗,流水冲洗30分钟,将花梗剪成长约2cm带腋芽的切段,先用70%的酒精溶液浸泡30秒钟,再用0.1%的升汞溶液浸泡8~10分钟,无菌水冲洗5遍,基部向下插在MS+BA3的培养基上,可使腋芽萌发为丛生芽
2)花梗节间的组织培养
取生长期在45天以内的蝴蝶兰花梗,经常规消毒后,斜切成1~1.5mm厚的薄片,平放在固体斜面培养基上。

置温度24~28℃,光照强度500Lx,每天光照16小时处培养。

培养基用1.2倍的V&W无机盐配方,加肌醇100,维生素B1、B6和烟酸各0.5,BA1mg/L,蔗糖2%,琼脂0.8%。

原球茎状球体形成较好。

二、继代增殖
在原球茎状球体形成后,于无菌条件下取出切成小块,转到新鲜培养基中继代。

在切块细小、稀疏的培养瓶内,群体生长较慢;而在切块较大而密集的瓶内,群体生长十分旺盛,表现出一定的群体效应。

因此须注意切块不可过小(直径>2mm),同一瓶内培养块数不应太少。

以MS为基本培养基,附加5~10ppm的BA和1ppm的NAA,最好附加10%体积的椰乳,可使圆球体继代增殖。

三、壮苗生根
蝴蝶兰圆球茎经长时间培养,在芽苗生长的同时,根也不断的生长,不必单独进行生根培养。

四、移栽驯化
出瓶的小苗要用清水将附在根部的培养基洗干净,栽植在洁净的水苔或椰壳糠上,放置阴凉处。

注意保持基质湿润和环境湿度及通风。

1个月后,小苗生长稳定,开始喷施液肥。

等到小苗有新叶长出时,便可移植到小盆或蕨板上。

出瓶后的植株一般2~3年便可开花。

2、请论述接种操作程序。

答:1)接种台的灭菌。

每次接种或继代繁殖前,应提前30分钟打开接种室和超净工作台上的紫外灯,照射20分钟,然后打开超净工作台的风机,吹风10分钟。

2)接种人员的灭菌。

操作人员进入接种室前,用肥皂和清水将手洗干净,接种前先用香皂将双手洗干净,再用75%酒精棉球认真擦洗,换上经过消毒的工作服和拖鞋,并戴上工作帽和口罩。

3)接种工具的灭菌。

从培养室内拿来的瓶苗要用75%酒精擦拭,进行表面消毒后再放入工作台内。

接种前先点燃酒精灯,然后将解剖刀、镊子、剪子等在火焰上方灼烧后,晾于架上备用。

4)外植体的表面灭菌。

把培养材料放进70%的酒精中浸泡约30s,再在0.1%的升汞(氯化汞,HgCl2)中浸泡10min,或在10%的漂白粉上清液中浸泡10~15min,浸泡时可进行搅动,使植物材料与灭菌剂有良好的接触;然后用无菌水冲洗3~5次。

5)外植体置入培养基表面。

将三角瓶或试管倾斜拿住,打开瓶盖前,先在酒精灯火焰上方烤一下瓶口,然后打开瓶盖,并尽快将外植体接种到培养基上。

注意,材料一定要嵌入培养基,而不要只是放在培养基的表面上。

盖住瓶盖以前,再在火焰上方烤一下,然后盖紧瓶盖。

6)接种后的整理。

接种结束后,清理和关闭超净工作台。
