四、案例分析题

15.渔民赵某于1992年出海打鱼，遇风浪一直未归。1998年其妻钱某不得已向法院申请宣告其死亡。赵某有两个孩子，分别为赵甲、赵乙，赵某夫妇有房屋6间，渔船1条(已经随赵某失踪而灭失了)，摩托车1辆。法院依法作出判决后，赵某留下的遗产开始继承。房屋1间由其父亲继承，其余财产均由钱某和赵甲、赵乙继承。赵某死后，钱某生活十分困难，1999年，钱某将摩托车卖给了同村的孙某。后迫于生活压力，钱某又将赵乙送给李某夫妇作为养子。2000年，钱某改嫁给周某。这件事情让赵某的父亲无法理解，经劝阻无效后，向法院提出要求自己作为赵甲的监护人，理由是钱某作为赵甲的监护人对其不利。不久，周某死亡。2001年，赵某回来了，原来当时被海风刮到A国，失去记忆，现被送回。请回答下列问题：

1.赵某的父亲是否有权请求人民法院变更赵甲的监护权?为什么?

2.赵某是否有权要求其父亲返还继承的1间房屋?为什么?

3.赵某是否有权要求孙某返还摩托车?为什么?

4.如果钱某对赵某仍然有感情，赵某与钱某的婚姻关系能否自动恢复?为什么?

5.赵某是否有权要求李某夫妇解除与赵乙的收养关系?为什么?

正确答案:

1.父母是未成年人的当然法定监护人，只有在父母确实无能力履行监护职责，以及确实明显不利于未成年人的情况下，才可能取消父母对子女的监护权。本案中，钱某改嫁是其应有的权利，不构成不利于未成年人的情况，因此，赵某的父亲无权要求改变钱某担任赵甲的监护人。

2.被宣告死亡的人回来后，因继承法而取得其财产的自然人应返还所取得的财产或者给予适当补偿，因此，赵某有权要求其父亲返还继承的1问房屋。

3.无权。如果原物已经被第三人合法取得的，可不予返还。孙某取得摩托车是合法取得的，因此，赵某无权要求其返还。

4.不能。被宣告死亡人的配偶已经再婚的，即使再婚后配偶他方又死亡的，其与配偶的婚姻关系不能自动恢复，但可通过再次登记而缔结婚姻关系。

5.无权。被宣告死亡人的子女被他人合法收养的，被宣告死亡人不能以收养未经其同意而主张收养无效，要解除收养关系应与收养人协商解决。

　Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I?ve ever had: Be bold and bre ? and mighty (强大的) forces will come to your aid.

　Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

　Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas ? even physical strength greater than most of us realize.

　Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the erage player. ?In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,? said Tim. ?I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet ? and stopped him cold.?

　Boldness ? a willingness to extend yourself to the extreme?is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

　So, always try to live a little bit beyond your abilities?and you?ll find your abilities are greater than you ever dreamed.

　25. Why was the author sometimes unable to reach his goal in the past?

　A. He faced huge risks. B. He lacked mighty forces.

　C. Fear prevented him from trying. D. Failure blocked his way to success.

　26. What is the implied meaning of the underlined part?

　A. Swallow more than you can digest. B. Act slightly above your abilities.

　C. Develop more mysterious powers. D. Learn to make creative decisions.

　27. What can be learned from Paragraph 5?

　A. Confidence grows more rapidly in adults. B. Trying without success is meaningless.

　C. Repeated failure creates a better life. D. Boldness can be gained little by little.

　C

　The wallet is heading for extinction. As a day-to-day essential, it will die off with the generation who read print newspapers. The kind of shopping-where you hand over notes and count out change in return?now hens only in the most minor of our retail encounters，like buying a bar of chocolate or a pint of milk from a corner shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher up the scale you go. At the most cutting-edge retail stores?Victoria Beckham on Dover Street, for instance?you don't go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.

　Which is nothing more or less than excellent service, if you he the money. But across society, the abstraction(抽象) of the idea of cash makes me uneasy. Maybe I'm just old-fashioned. But earning money isn't quick or easy for most of us. Isn't it a bit incredible that spending it should hen in half a blink(眨眼)of an eye? Doesn't a wallet?that time-honoured Friday-night feeling of pleasing, promising fatness?represent something that matters?

　But I'll lee the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet?the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets?is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass, smooth and unknowable as pebble(鹅卵石). Instead of digging through pieces of paper and peering into corners, we move our fingers left and right. No more counting out coins. Show your wallet, if you still he one. It may not be here much longer.

　28. What is hening to the wallet?

　A. It is disearing. B. It is being fattened.

　C. It is becoming costly. D. It is changing in style.

　29. What makes the author feel uncomfortable nowadays?

　A. Sing money is becoming a thing of the past.

　B. The pleasing Friday-night feeling is fading.

　C. Earning money is getting more difficult.

　D. Spending money is so fast and easy.

　30. Why does the author choose to write about what's hening to the wallet?

　A. It represents a change in the modern world.

　B. It has something to do with everybody's life.

　C. It marks the end of a time-honoured tradition.

　D. It is the concern of contemporary economists.

　31. What can we infer from the passage about the author?

　A. He is resistant to social changes.

　B. He is against technological progress.

　C. He feels reluctant to part with the traditional wallet.

　D. He feels insecure in the ever-changing modern world.

　I found out one time that doing a for for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were hing a final test. During the test, the girl sitting next to me whispered something, but I didn?t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I hened to he an extra one, so I took it out of my pocket and put it on her desk.

　Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could lee. I walked out of the room wondering why she had chosen to talk to me about all those things.

　Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl?s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn?t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a for by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

She showed me that hers was out of ink and would not write. I hened to he an extra one, so I took it out of my pocket and put it on her desk.

　我发现一个时间，做一个人能给你带来很多麻烦。当时我在第八年级，我们有一个最后的考验。在测试期间，坐在我旁边的女孩低声说了些什么，但我不明白。我倚在她的方式，发现她想问我是否有额外的笔。她发现她是我的墨水用完，不会写。我碰巧有一个额外的，所以我把它从我的口袋里，放在她的办公桌上。

　To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.

　Watch a good teacher, and you will see that he does not sit still before his class： he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about.

　The fact that a good teacher has some of the gifts of a good actor doesn?t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher?s work and the actor?s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage.

　A good teacher works in quite a different way. His audience takes an active part in his play： they ask and answer questions, they obey orders, and if they don?t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.

　I he known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.

　1. What is the text about ?

　A. How to become a good teacher.

　B. What a good teacher should do outside the classroom.

　C. What teachers and actors could learn from each other.

　C. knows how to act on the stage D. stands or sits still while teaching

　4. In what way is a teacher?s work different from an actor?s ?

　A. The teacher must learn everything by heart .

　B. He knows how to control his voice better than an actor .

　C. He has to deal with unexpected situations .

　D. He has to use more facial expressions .

　5. The main difference between students in class and a theatre audience is that ____.

　A. students can move around in the classroom

　B. students must keep silent while theatre audience needn?t

　C. no memory work is needed for the students

　D. the students must take part in their teachers? plays

　6. Why is it that some good teachers are unable to play well on the stage ?

　A. Nobody has taught them how to act on the stage .

　B. Their audiences are different .

　C. It is impossible for them to do so much memory work .

　D. They are not used to repeating exactly the same words .

　7. Which of the following is true ?

　B. A teacher cannot decide beforehand what exactly he is going to say in class .

　C. A teacher must speak louder than an actor .

　D. A teacher must he a better memory than an actor .

　To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.

　要成为一个好老师，你需要一些好演员的天赋;你必须能够抓住观众的注意力和兴趣;你必须是一个明确的扬声器，具有良好的，强有力的，悦耳的声音完全在你的控制之下;你必须能够按照你的教学，以明确其含义。

　Watch a good teacher, and you will see that he does not sit still before his class： he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about.

　看一个好老师，你会看到，他不坐他的课前，他代表整个时间他是教学;他走，用他的胳膊，手和手指来帮助他解释，他的脸表达感情。听他的，你会听到声音，质量(音色)和音乐注意到他的声音总是按照他所说的。

　The fact that a good teacher has some of the gifts of a good actor doesn?t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher?s work and the actor?s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage.

　事实上，一个好老师有一些好演员并不意味着礼物，他一定能够在舞台上表演好，有教师和演员的工作的。他说的话他熟记于心的很重要的差别;他必须准确地重复同样的话每次他扮演某个角色，甚至他的动作，他用自己的发音方式都是事先确定的(预先)。他所要做的是让这些用心学习的言语和行动似乎自然的舞台上。

　A good teacher works in quite a different way. His audience takes an active part in his play： they ask and answer questions, they obey orders, and if they don?t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.

　一个好老师的工作相当不同的方式。他的听众积极参与他的表演：他们提问和回答问题，他们服从命令，如果他们不理解的东西，他们这么说。老师必须满足听众的需要，这是他的学生。他不能了解他的心，但必须把它作为他走。

　I he known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.

　我知道有许多老师在课堂上是优秀的演员却不能在舞台上扮演角色，因为他们不能严格按照别人所写的。
