Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Passage 1Hotlines （热线）have become common in China. Some radio stations use hotlines to encourage the listeners to take part in the talk shows.That's a good idea. Yet, the fact is, some people do nothing but break the whole program.Some people know little about the topic（话题）under discussion. Sometimes they do not even know what the host(主持人)is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance(无知).Then the host has to answer and explain —how silly this is ! It wastes a lot of time. It seems that some people phone the hotlines in fun. They just want to let the listeners hear them. They don't care what the topic is, whether they themselves are interested in or how silly they appear to be. I'm totally bored by those people. It's necessary for radio stations to improve the hotline programs. In my opinion,if a caller doesn't know what is going on, the operator should not let the caller take part in it.41.We know from the sentence “Some people do nothing but break the wholeprogram" that____.( B )A. radio stations use hotlines in a wrong wayB. it is a factC. it is a good ideaD. some people have unclear thoughts42. The host has to answer and explain, ____ . ( B )A. for the host works hardB. because of the caller's ignoranceC. for the host likes talking to the callerD. because of a lot of questions raised by the caller43. The passage doesn't tell us the idea ________ . ( C )A. that some listeners phone the hotlines in funB. that some people just want to be heard by othersC. that some people who don't care what the topic is must have realized that they appear to be sillyD. what the hotline programs are44. Which of the following is not true? ( D )A. Some people know little about the topic under discussion.B. Some people do not know what the host is talking aboutC. Some people do not know what the show is aboutD. The writer tells us that the host is silly.45. What should the operator do if a caller doesn't know what is going on in the writer’s opinion?( B )A. not to let the caller call the programB. not let the caller take part in the programC. let the caller express his ideaD. feel bored by the caller Passage 2Stage plays（舞台剧）, at first, seem a lot like films. Both use actors and dialogue and scenery. But if you try to make a film by setting up a camera in front of the stage, you will find it won’t work. A film made in this way will leave the audience（观众）cold. And even worse you’ll be wasting a powerful tool --- the camera.A stage is actually a box. One side of the box has been removed(挪开) so the audience can see what’s going on inside. The actors remain at a fixed audience. In the film, however, the camera can bring the audience up close and fix their attention on small but important things: a frightened look, a whisper, a trembling of hands.The camera offers the film maker freedom allowing him to move easily across barriers(界限) of time and space. He can show his action in real cities and on real farms. He can also use the camera to change the scene dozens of times in one film. No expert of the stage can do this.46. The main idea of the text is that ____ . ( C )A. stage plays and films are two different kinds of artB. it is always disappointing to turn play into filmsC. films have certain advantages(长处) over stage playsD. the camera has made film making easy and possible47. What is wrong with making a film by setting up a camera before the stage ? ____( D )A. Fewer and fewer people will go to the theatre.B. The audience cannot see what is going on the stage.C. The scene cannot be changed from time to time.D. The powerful camera cannot be made good use of.48. Which of the following can show that the camera is a powerful tool ? ____( B )A. It can move easily.B. It can make small things look larger.C. It can show things in the future.D. It can give us a scene of realism （真实）.49. In what way are plays different from films? ( B )A. Films often use real scenery while plays don’t.B. Films can show the past while plays can’t.C. Films change scenes while plays don’t.D. Film audience can move while play audience can’t.50. A suitable title for this text is ____.( A )A. Stage Plays and FilmB. The Powerful CameraC. Fewer Plays, More FilmsD. Less Waste, More Freedom Passage 3The human nose has given to the language of the world many interesting expressions. Of course, this is not surprising. Without the nose, we could not breathe or smell. It is the part of the face that gives a person special character. Cyrano de Bergerac said that a large nose showed a great man courageous, manly and wise.A famous woman poet wished that she had two noses to smell a rose! Blaise Pascal made an interesting remark about Cleopatra’s（古埃及王后）nose. If it had been shorter, he said, it would have changed the whole face of the world!Man’s nose has had an important role in his imagination. Man has referred to the nose in many ways to express his emotions. Expressions dealing with the nose refer to human weakness: anger, pride, jealousy（嫉妒）and revenge（报复）.In English there are a number of phrases about the nose. For example, to hold up one’s nose expressed a basic human feeling ---pride. People can hold up their hoses at people, things and places. The phrase, to be led around by the nose, shows man’s weakness. A person who is led around by the nose lets other people control him.On the other hand, a person who follows his nose lets his instinct（本能）guide him. There are a number of others. However, it should be as plain as the nose on your face that the nose in more than an organ for breathing and smelling.51. The passage is about ______. ( B )A. an organ, with which people can breathe and smellB. the nose, which gives different and useful expressionsC. the nose giving a person special characterD. interesting remarks about the nose made by some people52. From the passage we know ______. ( C )A. “Cleopatra’s nose” changed the whole face of the world indeed.B. Cleopatra had a strong will to change the whole look of the worldC. Cleopatra’s nose was not shortD. Cleopatra hoped that people would change the whole face of the world53. The nose expressed ______. ( C )A. some human weakness or otherB. people’s shortcomingsC. people’s different emotionsD. human feeling in bad sense54. A person who follows his nose ______. ( D )A. won’t take others’ adviceB. is easily controlled by othersC. is weak-mindedD. has will of his own55. How many expressions about the nose are mentioned in the passage? ( C )A. TwoB. ThreeC. FourD. FiveⅣCloze (1 20=20 POINTS)Directions: There are 10 blanks in the following passage. For each blank there are four choices marked A, B, C, and D. You should choose the one that best fits into the passage.Mrs. White gave music lessons at a school. She had a good voice, __56___ some of her high notes （高音）sounded like a door that _57__ oiling.

教育学平时作业(1)
教育学平时作业（11版教材）姓名：___________________________学号：___________________________专业：___________________________教学点：___________________________平时作业一(1-3章)一、辨析并说理由。
(1)教育是人类和动物界都具有的一种现象。
答：错误。
尽管在动物界，尤其是高等动物界的代与代之间虽也存在着类似于人类的“教育”和“教”与“学”现象，但这两种表面类似的现象在本质上是不同的。
1．所谓动物的“教育”和“教学”完全是一种基于生存本能的自发行为，而不是后天的习得行为。
它的产生与动物的生理需求直接相关，其内容也紧紧围绕生存本能。
无论是鸟会飞、鸭游水，还是猫捉老鼠、动物表演等，都是建立在本能基础上的，而非教育的结果。
人类的教育活动与动物相比，最大的差别在其社会性上。
人的教育需要，不是直接产生于生物本能，而是产生于社会延续与发展的需要。
教育一开始就是一种为了社会的活动。
2．动物没有语言，不具备将个体经验积累起来向他人传递的能力。
“动物不能把同类的不同特征汇集起来，它们不能为同类的共同利益和方便作出任何贡献。
”（《马克思恩格斯全集》第12卷，人民出版社1979年版，第147页。
）因此，所谓动物的“教育”只能一直停留在第一信号系统的水平上，它不可能有“类”的经验，也不可能进行个体之间的经验交流和传递，因而也就不可能通过“教育”使动物一代胜过一代。
尽管一代代的老猫都“教”小猫捕鼠，但猫的本领始终不过是捕鼠而已。
由此可见，教育是人类社会特有的活动。
正像社会性是人与其他动物的本质区别，因此需要用“人”这个词把人与动物区别开来一样，教育是人类特有的一种有意识的活动教育是人类社会特有的传递经验的形式 教育是有意识的以影响人的身心发展为目标的社会活动至此，可以使我们对教育的本质认识得更加明确。
近年来，有人把教育的阶级性、生产性、福利性等也视为教育的本质特性。
