你运气好啊.完整版的.考试作文几乎不会超出以下内容.希望对你有所帮助.L1 P14 Why does the author tell s not to be afraid to ask stupid questions? The author thinks that many apparently naive inquiries like why grass is green, or why the sn is round, or why we need 55,000 unclear weapons in the world ——are really deep questions. He says when you try to get the answers, you will gain deep understanding of the things. Its also important to know, as well as you can, what it is that you dont know, and asking questions is the way. He also tell us to ask stupid questions requires courage on the part of the asker and knowledge and patience on the part of the answers. And dont confine your learning to schoolwork. Discuss ideas in depth with friends. Its much brave to ask questions even when theres a prospect of ridicule than to suppress your questions and become deadened to the world around you. L2 Icons P30 What are the factors to shift the hero-worship to the celebrity-worship? The new forms of media——photography, moving pictures, radio and television are the main factors. The reproduction of photos in newspapers turned famous people into celebrities whose dress, appearance, and personal habits were widely commented upon. Slowly, the focus of public attention began to shift away from knowing what such people did to knowing what looked like. The shift was accelerated by the arrival of moving pictures. Between 1901 and 1914, 74 percent of the magazine articles about famous people were about political leaders,inventors, inventors, professionals, and businessmen. After 1922, however, most articles were about movie stars. With the arrival of television, the faces of the stars became as familiar as those we saw across the breakfast table. We came to know more about the lives of the celebrities than we did about most of the people we know personally. Less than seventy years after the appearance of the first movimg pictures, the shift from hero-worship to celebrity-worship was complete. L3 GO-GO AMERICAN P46 What is the Americans attitude towards time?Give necessary examples. In the United States, many people keenly feel the shortness of each lifetime. They are aware that once a day in their life is gone, it will never come back. And Americans believe no one stands still .If you are not moving ahead, you are falling behind. So they value time and want every minte to count. This attitde towards time is shown in the fast pace of life in the country. Whatever they do they always seem to be in a rush. You find people hurrying to get where they are going. They hurry to eating places for a mea and finish it as quickly as possible. Also Americans do what they can to save time. They produce a lot of labour-saving devices such as clothes-and dish-washers; they rapidly communicate through phone calls, telex and e-mail and cut down on personal contacts. L4 Take Over,Bosn! P62 Can you imagine what did Barret think of when he heard Snyders whisper Take over,bosn? Becase of thirst,Barret was almost out of mind. He rose several times and was a constant threat. But when he heard Snyder said“Take over, bosn, he had a strange feeling suddenly. He came to realize he would and must take over the task and be responsible for the rest. As long as he stopped others from the little water, they would always have hopes and wouldnt die soon. So he picked Snyders gun up and decided to hold off the other from the water until night when a ship saved them. L5 Are You Giving Your Kids Too Much? P78 Why parents overindulge their children? There are several reasons to explain why parents overindulge their children. One fairly common reason is that parents overindulge their chidren out of a sense of guilt. Parents who both hold down full-time jops may feel guilty about the amount of time they spend away from their children and may attempt to compensate by showering them with material possessions. Other parents overindulge because they want their children to have everything they had while growing up, along with those things the parents yearned for but didnt get. Still others are afraid to say no to their childrens denless requests for toys for fear that their children will feel unloved or will be ridiculed if thy dont have the same playthings their friends have. L6 Culture Shock P94 What are four stages that people go through when they experience situations that are very different from those to which they are accustomed? Stage one is a honeymoon phase, during which the new experience is perceived to be interesting, picturesque, entertaining, and charming. You may notice several superficial differences such as music, food, and clothing, and the fresh apeal of the new experience keeps you feeling interested and positive. When you stay in a new envirnment for a while, you move to stage two-the crisis stage-in which the shine wears off and day-to-day realities sink in. In relationship, you notie annoying habits;in a new country, you find barriers to establishing connections or to learning the language beyond a few polite phrases. If you stick with the experience and try to deal with it realistically, you will probably move to the third phase:recovery. In recovery, you learn the systems, procedures, language or nonverbal behaviors of the new environment so that you can cope with it on the basis of some mastery, competence, and comfort. Finally,when you feel that you function well and almost automatically in the new culture, you will move to the fourth phase:adjustment. L7 The Model Millionaire(I) P108 Suppose you are the millionaire.Explain how you get to know Hughie Erskine and what you do in return for the pound he gave you when you first met. I am Baron Hausberg. I have enough money to buy the whole of London. One day, on a whim I asked my artist friend Alan Trevor to pain me as a beggar. Alan had almost finished the picture when a very charming young man walked into his studio.I suppose he must have been very sympathetic with me, for when Alan was away a minute, the young man quickly put a pound into my hat. I was startled for a moment, but I was pleased when I realized that he took me for a real begger. Later I learned from Alan all about this young man:he was poor, and could not marry the girl he loved because her father wouldnt let them unless he had 10,000 pounds.Touched by the young mans spirit of kindness, I decided to help him. The next day I had a cheque for 10,000 pounds delivered to him as a wedding gift. L8 The Model Millionaire(II) P123 Retell the story The Model Millionaire in about 150 words, concluding your retelling with a one-sentence comment. Hughie Erskine was a charming young man who was in love with a nice girl called Laura Merton.Lauras father made it clear to Hughie that he would not marry his daughter to him until Hughie had ten thousand pounds. One day,Hughie went to see his artist friend Alan Trevor in his studio. There he found his friend painting a beggar, who was an old man in rags.Hughie felt so sorry for the poor model that he gave him the only pound he had. The old model was actually a millionaire.When he heard all about Hughie and Laura, and their problem, he had a cheque for ten thousand pounds delivered to him the very next day.The couple were happily married,and the beggar attended their wedding. The story shows that a genuine millionaire is not one who has, but who give. L9 Only Three More Days P139 The author got a solution finally. What was the solution? Was it risky? He laid out the diaries in two big steel suitcases. Over them he palced a number of his broadcast scripts, each page of which had been stamped by the military and civilian censors as passed for broadcast. On top he put a few General Staff maps he had picked up from friends. Then he phoned the Gestapo Headquarters to say he had a couple of suicases full of his dispatches, broadcasts and notes that he wanted to take out of the country. As he was flying off early the next day, there would be no time for Gestapo official at the airfield to go over the contents. Could they take a look now,if he brought them over;and if they approved, put a Gestapo seal on the suitcases so he wouldnt be held up at the airport? Yes,it was risky. He thought life in the Third Reich had always been risky. It was worth a try L10 The Washwoman P155 Describe the situation that“I”saw the old washwoman for last time. One evening, while Mother was sitting near the oil lamp mending a shirt, the door opened and a small puff of steam, followed by a gigantic bag, entered the room. I ran toward the old woman and helped her unload her bag. She was even thinner now, more bent. Her head shook from side to side as though she were saying no. She could not utter a clear word, but mumbled something with her sunken mouth and pale lips. After the old woman had recovered somewhat, she told us that she had been ill badly. But as soon as she was able to stand on her feet once more, she began her washing. She said “I could not rest easy in my bed because of the wash. The wash would not let me die.……I dont want to be a burden on anyone!” L11 How I Served My Apprenticeship 170 Why was Andrew Carnegie so pround of the one dollor and twenty cents——the first pay he brought home? Carnegie was very pround of the one dollar and twenty cents he earned for the first time in his life when he was only twelve. The money, though small in amount, meant a great deal. First, when he got his first pay he felt that he had grown up. He was no longer a boy who had to depend on his parents; he had become a man who was able to help support the family, a contributing member. This was important because at that time life was hard for the family and it was difficult for his parents to manage alone. Also he though the money was the direct reward of honest manual labor. It represented a week of very hard work. This money gave him the greatest satisfaction of being rewarded for what he had done. L12 A Friend of the Environment P185 Why did Rachel Carson write the Silent Spring? Whats the content of it? Because she felt that the wonders of Nature are precious and permanent, and much of Nature was forever beyond the destruction of man. But then she discovered she was wrong. She learned with sadness that little in Nature is truly beyond the tampering reach of man. Then, She wrote the book Silent Spring to sound a startling warming to mankind and the book showed quite clearly that man was endangering himself and everything else on this planet by his indiscriminate use of chemical pesticides. As her title suggests, Miss Carson was saying that there might come a springtime that would indeed be silent because the birds, as well as other creatures, and plants would have been destroyed by the man-made poisons used to kill crop-threateding insects. L13 Who Shall Dwell? P201 In the story Who shall Dwell?, how did the fatners attitude towards the neighbours change? What brought about the change? When the bomb alert came, the father was clear that he had built the shelter for his own family, and that he would not let anybody else in. So when his neighbours came and asked to share the shelter he rejected them flatly. When a monther begged him to take her little girl in , he did not know what to do. At that monent his wife dashed outside and pushed the girl in. her act set him thinking hard. Just a moment before the first bomb struck he made a big decision. After giving his elder son a few instructions, he stepped out and shoved two children into the shelter. He stood beside his wife, ready to spend the last minute with her. His change seemed sudden, but was actually quite natural. He loved his children, so he was greatly affected by the monthers plea and gave the chance of surival to the two children. Also his love for his wife led him to follow her example. L14 Cipher in the Snow P218 Describe Cliff Evans life before his sudden death. Cliff Evans lived with his mother, stepfather and five younger half brothers and sisters. His stepfather had never legally adopted him, nor did he show any affection for him. At home Cliff didnt talk much and had never told his family about his problems. When he began school, he was timid but eager to learn. And his IQ was pretty good. Then in the third grade a teacher wrote in the school record that he was uncooperative and slow. Since then he had never got any encouragement from his teachers. Gradually, the child had no more confidence left. He never smiled nor talked much. He had no friends; he had never belonged to a club, never played on a team and never held an office. He came to school by himself and left by himself. In class, he would sit back in the last seat. Finally he became silent and lonely. He became nothing. L15 Bribery——An Inevitable Evil? P232 What are the major forms of bribery? Bribery can be classified into three broad categories. The first category consisits of large amounts of money paid for political purposes or to secre major contracts. For example, a certain American company offered big sums of money to support a U.S. presidential candidate when it was nder investigation. Also in order to get big contracts, such payments are often made to ruling families or their close advisers. The second category covers payments made to obtain quicker official approval of some project. In such cases, the money is often paid to key goverment officials concerned. The third category involves payments made in certain countries to make a business deal easy to get approved. For instance, a foreign company may pay to get permission to import equipment. A common type of this category is the facilitating payment to clear cargoes. These are smaller sums of money paid to customs officials. L16 A Social Event P250 What do you know about Randy and Carle in A Social Even? Why are they anxious to get invited to Scottys funeral? Randy and Carole are a young Hollywood couple. They have been married only a short time. Both have achieved a certain degree of success in pictures, but their careers in the show business are still in the promising stage. Scotty Woodrow, a world-famous movie star has just died, and Randy and Carole are anxious to go to his funeral, which will be a gathering of celebrities and is regarded as a big social event. It is said that flowers have come from the U.S. President and the British Queen. Randy and Carole think it is extremely important for their career to be seen there with a lot of big shots. But they havet got an invitation while some of their Hollywood friends, also young actors and actresses like themselves, have been invited. Thats why they are worried and are trying hard to find ways of getting themselves invited in the last minute.

我是阿晨

Unit 5 Text A 关于饮食的错误观点 许多原始时代的人都相信,若是吃了某种动物就能使他们自己得到那种动物所具备的某些优良特性。例如,他们认为,若是吃鹿肉就能跑得跟鹿一样快。某些野蛮部落相信,若把在战斗中表现得很勇敢的敌人的肉吃掉了,那就会使自己变得勇敢。吃人现象的开始发生可就是因为人们渴望使自己变得像敌人一样的强壮和勇敢。 在文明社会的人们中,一度认为生姜的根具有魔力可以改善人的记忆力;蛋类的食品能使人的嗓音变得甜美;西红柿也被认为有魔力,他们把西红柿叫做爱情苹果,认为吃了西红柿的人会堕入情网。 关于西红柿后来又生出来一种错误观点——西红柿有毒。那些认为西红柿有毒的人们,若是知道在第二次世界大战期间,数百万磅的西红柿曾供应给海外的士兵食用,他们该会大吃一惊。 即使在今天,关于饮食也有许许多多的错误观点,其中有些错误观点流传甚广。 一种错误观点就是认为鱼是的健脑食品,就象吃鱼对人的肌肉、皮肤和骨骼发育有好处一样。但是没有任何人能证明鱼对人的大脑比其他许多种食物都更加有什么好处。 还有一种错误观点就是,就餐时不应该喝水,用水把食物冲到胃里去代替咀嚼并不是一个好主意。但是人们发现就餐时喝点水是有好处的,水可以使胃的消化液更加自由地流动,这有助于消化食物。 科学家告诉我们饮用混和食物的一些观点是没有根据的。几年前有种看法很普遍,那就是在同一餐中绝不应当又喝橙汗又喝牛奶,因为橙汗中的酸性物质会使年奶凝结成乳块而难以消化。事实上,牛奶在胃里总是遇到胃的消化液就会变成乳块的,把牛奶变成乳块是在消化牛奶过程中的第一个步。还有一种类似的错误观点,就是在同一餐中既吃鱼又吃冰淇淋会形成一种有毒的化合物。 关于搭配食物还有一种错误观点,那就是在同一餐中不能既吃蛋白质又吃碳水化合物。例如,很多人认为是碳水化合物食品的面包,的确面包中碳水化合物是主要的成份,但面包里也含有蛋白质。同理,牛奶也许是既含蛋白质也含碳水化合物的的一种食品。说不能把肉和土豆一起吃,就像说不能吃面包或喝牛奶一样的愚蠢。 Unit 5 Text B 动物会思考吗? 人们经常会问这样一个问题:动物会思考吗?我相信有些动物是颇能思想的。很多动物能像孩子一样地游戏。我们注意到狗和猫是这样,但别的一些动物也是这样。 有些鸟类游戏时非常活泼,某些昆虫也是这样。蚂蚁尽管工作很勤劳,但仍有时间游戏。它们赛跑、摔跤,有时还一起进行模拟战争。它们从事这些游戏时,思想活动一定十分频繁。 不过也有很多动物从不玩耍。它们的思想似乎属于比较老成持重的一类。我们从没有见过青蛙参加什么游戏。它们无论什么时候都显得非常严肃。猫头鹰也是这样,它看起来总在思想什么重要问题。 动物在建造家园时要进行很多思维活动。鸟类搜寻它们能用来筑巢的东西。在做这件事的过程中它们总在思考。海狸在筑堤和建房时也会思考。它们考虑怎么找到材料,怎么放置它们并用泥巴把它们粘在一起。一些蜘蛛营造的“房子”,除了有思维能力的动物外,其他动物几乎不可能造出来。 动物既会思考,又会学习。一些动物比另一些动物学得快。尽管鹦鹉在别的方面挺笨,但能学会说话。朝鸫能学会模仿很多不同的声音。马很快就能学会很多与它该干的活儿有关的事。牧羊犬对很多事情不如有些狗知道的多,可它非常懂得怎样看管羊群。 虽然动物能思考和学习,但它们并不能像人那样真正改进自己的工作方法。每种鸟都有自己的筑巢方法,但始终固守原样。别的动物也是这样,它们没有新花样,也不相互学习。但我们知道,人一直在寻求建造房屋的新方法,并改进了几乎所有的劳动方法。 有许多事情动物知道怎么做。它们或者好像不学就会,或者我们不了解它们是怎么学会的。据说动物凭本能就会做这些事,但没人能说清本能是什么。正是靠了这种本能鸟类才会筑巢,海狸才会筑堤造窝。如果这些事情能像人设计新房子那样有所计划和周密考虑,动物的巢窝式样就应该有所变化,有所改进。 我已经谈过海狸的建筑本能。一个英国绅士捉了只小海狸,先把它关在笼子里,过了一会儿绅士把笼子拿进一间屋子,并把海狸放了出来。这间屋里有各种各样的东西。小海狸一放出来,就开始运用它的建筑本能。它把所能找到的各种东西都集中到一块,像刷子、篮子、靴子、衣服、棍棒、小煤块等,然后开始摆放它们,好象要筑堤一样。假使海狸真有智慧的话,它应该知道,在没有水的地方是不用去筑堤的。 很明显,动物能够像我们一样依靠感官学习,但它们几乎不思考所学的东西,这就是为什么它们不能更快进步的原因。即使像大象和狗这样最聪明的动物,对它们看到和听到的东西也思考不多。这还不是全部原因。有些东西是我们人能理解的,动物对它们却一无所知。它们完全不知道超出它们范围以外发生的事。它们的头脑与我们人类如此不同,以致它们毫无正误之分。 Unit 6 Text A 钻石 钻石是一种稀有矿石,它美丽,并且很有使用价值。钻石是自然界中发现的最坚硬的物质。这意味着钻石能够切割其他任何物质的表面,只有钻石才能在钻石上弄出很浅的划痕。 钻石是由碳构成的,碳存在于一切有生命的物体中,包括动物与植物在内。地球内大部分的碳来自从前的活的物体。 科学家们知道,极高的温度和压力能把碳变成钻石。这种高温和高压只存在于地球内部深处炽热的液态溶岩中。人们认为,千百万年以前液态熔岩从地球的深处通过地壳的裂缝向上挤,液态熔岩冷却后,其中的碳便变成了钻石晶体。 世界上只有四个地区发现钻石储藏量最丰富。 第一个的产地在印度。几千年前印度就发现了钻石。17世纪时,来自欧洲的旅行家们将这些美丽的石头从印度带回欧洲,钻石从此便得到了欧洲各国国王与王后的喜爱。 18世纪20年代巴西发现了钻石,这次发现也是适逢其时,因为经过2500年的开采,印度的钻石供应已最终告罄。 19世纪时,俄国和南非都发现了一个重要的钻石矿区。当今,多数工业用钻石产自俄罗斯,制作珠宝用的钻石则大部分来自南非,在所开采的全部钻石中,只有25%的质量适合切割成珠宝。 印度的大部分钻石是在河床上发现的。人们从河底捧起一把把的砂砾,然后从中挑捡钻石。二万年前地球上有些地方为大片的冲川覆盖,这些钻石可能是从其形成的地方被冰川带到印度的。 不过现在大部分钻石已不是从河床上找到的,而是从地下深处叫做火山筒的岩组中开采出来的。科学家相信,火山筒是火山的一部分,它是熔岩向上涌出地壳时形成的。含有钻石的岩石叫蓝地,因为它多少有点发蓝。蓝地被炸成大块岩石,然后用升降机将它们运到地面。碾碎这些岩石时必须非常小心,这样钻石才不致被破坏。然后把碾碎的石料送往洗选台。洗选台的面板上涂出厚厚一层油脂,碎石就从这上面流过。因为钻石会让油脂粘住,这样它们就被留下了,而碎石和泥浆则从洗矿台上流走。 刚开采出来的钻石并没有什么吸引人的地方。它们只是些灰色的,看起来没溜溜的小圆石头。有经验的钻石开采者能立即认出哪些是钻石,但也有些人随身带着一块不寻常的小圆石头,过了好几个星期才明白他有了块钻石。 Unit 6 Text B 动物和植物的区别 如果有人问你,“动物和植物有什么不同?”你准备怎么回答?你首先想到的可能是植物有叶子、根、花,而动物则没有。但这并不正确:因为有许多植物既没有根,也没有叶、也没有花,而有些动物好象这三样都有。 你抬头仰望天空,然后再低头俯视脚下的大地。你会认为要分辨哪儿是天,哪儿是地,是轻而易举的事。但是如果你住在宽旷开阔的农村或者住在海边,当你极目远眺那天地会合之处时,你常常会发现分辩天和地确有几分困难。你只能看到远方烟一般的蓝色薄雾,那就是天和地的分界线。但这条分界结从哪里开始,到哪里结束,你不可能说清楚。 整个自然界也恰恰是这样。你可以观看伫立树下的牛群或者捕捉清晨在牵牛花冠中吮吸甜汁的蜜蜂,这时如果有人问你能否区别动物和植物,你会觉得好笑。 但假使你撇开这些日常熟悉的东西,而去研究只有用放大镜才能看到的东西,你会发现有许多东西使你迷惑不解。你会发现有的植物并没有根、叶、花或种子,你还会发现有些动物没有头、脚、眼、嘴或者胃。 大自然的研究者并不满足于猜测,而是日复一日的观察物体发生的变化,因此能够看到大多数人疏所的许多东西。因此他们发现了动物与植物的真正区别在于它们的活动而不在于它们的外形。 现在我们已经了解,所有种类的海中约有四分之一是动物,可是几年前它们却全都被归类为植物。长期以来人们一直认为动物和植物的主要区别是前者能随处活动而后者却不能。但这一区别经常不起作用。 那么我们怎样才能知道一个活的物体究竟是植物还是动物?植物能靠无机物生活,它们具有一种能力,可以把泥土、空气和水变为某些物质,这些物质进入植物内部并且成为植物自身的一部分。动物的生活只能依靠植物由无机物转变成的植物性物质。虽然动物也需要某些无机食物,但不能只靠吃无机物生活。 一切保持我们身体健壮或使我们身体成长的食物原本都是植物形式的。如果地球上不是先有植物并且使地球能够适宜更高一级生物居住,无论鸟、鱼,还是其他任何动物都不可能在地球上生存。 植物是真正的仙人,他们始终在我们周围创造奇迹。它们的根部深入地下,从中获取宝藏。它们向空中展开宽阔的叶面,从中吸收财富。它们依靠获得的这些物质开出美丽的花朵,结出美味的果实和长出金色的谷物。 让我们更加认真地研究一下植物是怎样生长的。它的根部向下深入土壤。如果它遇不到水,很快便会枯死。如果它能遇到水,便将水吸入,并把水转变成植物的液汁。除了水以外,植物的根还吸收土壤中那些溶于水的物质。 由此你可以看到植物的食物与动物的食物在哪些方面有所区别。 Unit 7 Text A 家庭 家庭一词对不同的人具有不同的含义,甚至词典上给出的定义也有几种:“一群由血缘或者婚姻联系在一起的人”,“两个成人和他们的孩子”,“同一祖先传下的所有后裔”,“一户人家”等等。有些人认为家庭包括母亲、父亲和他们的孩子;另一些人则认为家庭还包括(外)祖父、(外)祖母、父母的兄弟姐妹以及他们的子女。对于我们有些人来说,家庭意味着离家远住的亲人;对另一些人来说,有家只不过意味着有孩子。有些家庭历史悠久,另一些家庭则对自己的祖先知之甚少。每个家庭,无论历史长短,成员多少,传统抑或现代,都有其家庭的含义。那是一种通过共同生活、互相帮助、同甘共苦而形成的归属感、情爱感和安全感。 家庭基本上可分两类:核心家庭和大家庭。核心家庭通常由双亲(父亲和母亲)及子女组成。父亲和母亲形成核心家庭中的核心,或者说是中心。子女留在核心家庭中直到到长大或婚嫁,然后再组成新的核心家庭。 大家庭非常大,一个大家庭往往有很多核心家庭。大家庭包括子女、父母、(外)祖父母、叔伯舅、姑姨婶 、堂(表)兄妹。这些家庭成员由血缘关系(如:(外)祖父母、父母、子女、兄弟、姐妹等)或者婚姻关系(丈夫、妻子、岳母、婆婆等)联系在一起。大家庭中的成员都相互丛有亲缘关系,所以称为亲戚。 传统上,大家庭的全部成员都住在同一地区。然而,随着农业社会转变成工业社会,许多核心家庭离家到外地寻找工作。在现今的工业社会中,多数核心家庭的成员住在一起,而大部分大家庭的成员并不这样。因此我们可以这样说,随着社会越来越工业化,核心家庭变得比大家庭更重要。 在像美国这样的后工业化国家里,甚至核心家庭也在变。随着父母想要更少的子女,和无子女家庭数量的增长,核心家庭也变得更小。传统上,核心家庭中的父亲挣钱养家,母亲照顾家和孩子。今天在美国,50%以上的核心家庭的父亲和母亲都挣钱养家,成为双收入家庭。少数家庭由母亲挣钱养家而父亲理家和看孩子。因为越来越多的父母开始离异,所以许多核心家庭也在“分裂”。 核心家庭的这种“分裂”会产生什么样的结果呢?社会学家现在讨论两种新的家庭形式:单亲家庭和再婚家庭。美国全部家庭中有将近20%是单亲家庭,而85%的单亲家庭是单亲母亲。大多数单亲父母认为一个人照顾家庭有困难,所以离婚不久他们又再结婚,这就构成了再婚家庭。社会学家对这两类新家庭形式的研究,将能给我们提供有关后工业化时代核心家庭未来发展的更多情况。 Unit 7 Text B 变化中的美国家庭 虽然家庭的结构在国与国之间可能差异很大,但它对全世界的人都是十分重要的。在美国,如同世界上其它许多国家一样,家庭正在发生变化。在一代人或者两代人之前,传统家庭是惯常现象,在那里父亲是一家之主。今天,现代家庭更在现代家庭中,父母是平等的伴侣。尽管传统家庭和现代家庭有一些相似之处,但他们之间仍有些重大的差别。 昔日的传统家庭与现的现代家庭有几点是相似的。传统家庭是核心家庭,现代家庭也是。传统家庭中父亲的责任是养活全家,同样,现代家庭中养家也理应是父亲的责任。传统家庭中的母亲负责孩子的身体和情感需要,现代家庭中的母亲也是这样。 另一方面,传统家庭与现代家庭之间存在某些很大的差别。第一个重要差异是男人的角色。传统家庭中,丈夫是家中外出工作的人,所以是一家之主。如果妻子也外出挣钱,人们会认为这家的丈夫没本事养家。今天,许多家庭的夫妻都外出工作,所以都是一家之主。此外,传统家庭中经济开支的重要决定通常都是丈夫说了算,而在现代家庭中,丈夫要与工作的妻子共同决定。还有,传统家庭的丈夫不帮助妻子理家或做饭。等他回家时饭已做好。与此相反,现代家庭中的丈夫在家里帮助有工作的妻子,也干一些家务活,并且经常下厨房做饭。 第二个差别是妇女的角色,传统家庭中,女人在婚后的头几年可能工作挣钱,但怀孕之后通常就放弃了工作。他的主要任务是照顾家人和料理家务。现在的许多家庭则与此相反,即使有了孩子,现代女性也在外面工作。她现在是一身二任,所以她比传统家庭中的母亲更忙。传统的母亲学会过日子要量入为出,不超出丈夫的收入。另一方面,现代家庭中的妻子不必这样,因为家里有两份收入。 最后一个差别是孩子的角色。在传统家庭中,孩子是由母亲照料的,因为她不出外工作。而现在的学龄前儿童由于母亲参加了工作,就要按时去托儿所或者由保姆照看。传统家庭中的学龄儿童依赖性更大,因为母亲帮助他们准备好上学用的东西、给他们做早餐。相反,现代家庭的儿童更自立,他们早晨必须起得很早,做好上学准备。母亲因为忙于准备上班,所以孩子甚至只好自己准备早餐。 最后,今日的美国家庭与五十年前不同。在现代家庭中,由于越来越多的妇女外出工作,父亲、母亲、孩子的角色都发生了改变。下个世纪可能给美国的家庭结构带来更大的变化,能够看到这些变化是将很有趣的。 Unit 8 Text A 卫星通信 20世纪初远程信息传递和接收有四种强有力的手段,它们是印刷、照相、电报和电话。到20世纪中期,无线电和电视都已成为无可争议的声像传送手段。1964年,东京奥运会成为第一个通过卫星传送的节目。 为了能通过卫星传送像奥运会这样的比赛项目,电视信号要先转换成无线电波,然后从某个地面发射站把无线电波送上轨道卫星。卫星收到无线电波之后,再把它们发回地球,由地球上的另一个地面站接收信号,并把它们转换回电视信号。因为任何形式的声音或图像信号都能变成无线电波,所以卫星不仅能传送电视广播节目,还可以传送电话和书籍、杂志一类的印刷品。 卫星能够传送信息、计算机能够存储信息和电视能够显示信息,把这三者结合起来就能使每个家庭成为教育和娱乐中心。从理论上说,每个人都能接触无限的信息量。 1974年美国的“空中教师”卫星把教育节目传送到边远地区的课堂,这显示了通信卫星的另一个重要用途。1975年,印度有很多人第一次看到电视,当时他们观看的是有关农业和健康的节目。 有些人住的地区与外界隔绝,交通十分不便,卫星还显示了它们怎样向他们提供帮助。例如,这类地区的保健工作者可以把患者受伤的照片传送给远方的医生。然后他就能够根据医生的指示照料患者。 然而通信卫星用得最多的还是传送电话。大部分电话信息要走40000英里才能到达某个卫星然后返回地球。10年前,一颗卫星能够同时接收和传送33000多对通话。现在一颗卫星就能传送100000多对通话和几个电视频道节目——而这一切都是同时进行的。 电信能使我们迅速和方便使用世界各地发来的信息,不过有些人担心我们隐私会因此有被暴露的危险。如果计算机中存在私人信息,那么只有人能为这项服务付费,就可以很容易地通过卫星把它传送给这个人。 另一个担心是电信系统会使人们今后互相隔绝。当人们在家里就能购物,不用离开家就能办理银行业务,能够在电视上看到想看的电影,还能得到所需要的任何信息,那么人们之间的接触就不会有那么多了。 重要的是要能认识到,同一种技术既能有利,也能有害,我们应该认真控制新的技术,防止有害的事情发生。正如电信专家所说,“我们必须牢记,解决问题的办法不在技术本身。……聪明地利用技术将能使我们成功。” Unit 8 Text B 关于空气人们还不了解什么 我们周围的空气对每个人都很重要,没有空气我们就不能生存。每个人都懂得这一点,但是空气在许多其它方面也是必需的——这些方面并不总是如此明显和广为人知。 譬如说,如果没有空气,就不会有声音。声音通过空气传播,没有空气的地方也就不会有声音。没有空气,就不会有火,也不会有轿车或卡车,因为发动机需要空气才能工作。 没有空气就没有风或云。如同我们所知道的那样,也就没有了天气。夜间会很冷,白天会很热。因为没有大气保护我们不受太阳致命射线的照射,我们将被迫寻找地方来遮蔽阳光。 大气指的是包围着地球的全部空气,大气压力是靠近地球表面的全部空气的重量。假如没有大气压力,我们就不会有汽车轮胎,因为如果轮胎表面不受大气压力的作用,轮胎就会爆裂。 大气是由几百英里厚的各种气体的海洋构成的,广袤而又强大。它给予我们身体的压力超过每平方英寸14磅。压在我们肩膀上的细空气柱子几乎重达2000磅,但是我们的身体的构造方式使得这个重量不会把我们压坏。 这个巨大的空气海洋中蕴藏的能量比我们地球上全部的煤、石油和天然气所含的能量都要多。大气中聚集着电能,就象堤坝里收集和存储着水一样。人们知道空气中有电能已经好几百年了。人们曾惊讶地凝视 闪电使暴风雨的天空出现耀亮的图案。但对大气中电的全面研究直到研制出无线电和雷达之后才成为可能。 科学家西德尼·查普曼博曾试图解释环绕地球的电场。他认为强大的太阳风暴能够产生大量的电能。这种电能存在一种叫氢气的很轻的气体中。地球把氢气吸向它,围绕在它的表面上形成一个几千英尺厚的环。这个庞大的太空环是一股强大的电能流。这个环有时会下降,弯入大气层的底层,结果引起了奇怪的电效应。 查普曼博士的看法说明了很多问题。人们早就知道地球内部有一个电场,它的运动方式和大气中所含电能的运动方式十分一样。科学家们现在相信,大气中的电能导致地球内部电能地流动。 如果我们能够学会控制大气中的能量,我们将拥有无穷无尽的能源供应。很多科学家正在努力弄清怎样控制它。现在像我们这些不是科学家的人甚至也开始注意空气了。我们认识到,现在空气所含的成分和多年前不同。汽车、飞机、工厂以及核爆炸往大气中增加了很多尘埃和废气。现在是应该学会怎样保护我们的大气——人类世界的屋顶的时候了。
