文章难度B/C级Bedwetting （尿床）Millions of kids and teenagers from every part of the world wet the bed every single night. It’s so common that there are probably other kids in your class who do it. Most kids don’t tell their friends, so it’s easy to feel kind of alone, like you might be the only one on the whole planet who wets the bed. ___1___.The fancy name for bedwetting is nocturnal enuresis. Enuresis runs in families. This means that if you urinate, or pee, while you are asleep, there’s a good chance that a close relative also did it when he or she was a kid. __2__.The most important thing to remember is that no one wets the bed on purpose. It doesn’t mean that you’re lazy or a slob. __3__. For some reason, kids who wet the bed are not able to feel that their bladders is full and don’t wake up to pee in the toilet. Sometimes a kid who wets the bed will have a realistic dream that he’s in the bathroom peeing –only to wake up later and discover he’s all wet. May kids who wet the bed are very deep sleepers. ___4___.Some kids who wet the bed do it every single night. Others wet some nights and are dry on others. A lot of kids say that they seem to be drier when they sleep at a friend’s or a relative’s house. __5__. So the brain may be thinking, “Hey, Don’t wet someone else’s bed! ”This can help you stay dry if you’re not aware of it.A. The good news is that almost all kids who wet the bed eventually stop.B. Trying to wake up someone who wets the bed is often like trying to wake a log—they just stay asleep.C. It’s something you can’t help doing.D. just like you may have inherited your mom’s blue eyes or your uncles’long legs, you probably inherited bedwetting, too.E. That’s because kids who are anxious about wetting the bed may no sleep much or only very lightly.F. But you are not alone.答案与解析1．文章主题分析：1．Millions of kids and teenagers from every part of the world wet the bed every 2．single night. It’s so common that there are probably other kids in your class 3．who do it.补充：thousands of: 数以千计的。
英语阅读二(第六课)中英对照KEEPING FOOD ON THE TABLE
This productivity, however, has its price. Intensive cultivation exposes the earth to the damaging forces of nature. Every year wind and water remove tons of rich soil from the nation’s
ers are building terraces on hilly fields, rotating their crops, and using new plowing methods to cut soil losses significantly. Substantial progress has been made, but soil erosion is far from being under control.很明显，为了避免最终出现的生态灾难，应该采取别的措施。自然资源保护论者坚持认为出路在于推出更新更好的农业技术。为了大幅度地减少土壤损失，农民正在山坡地上修梯田，轮种庄稼并采用新的耕作方法。这一切都取得了重大成就，但土壤侵蚀问题仍远未得到控制。

KEEPING FOOD ON THE TABLE
It’s early August and the countryside appears peaceful. Planting庄稼 has long been finished and the fields are alive with strong, healthy crops. Soybeans and wheat are flourishing under the hot summer sun, and the corn, which was “knee-high by the fourth of July”, is now well over six feet tall. Herds of dairy and beef cattle are grazing peacefully in rolling pastures which surround big, red barns and neat, white farmhouses. Everything as far as the eye can see radiates a sense of prosperity. Welcome to the Midwest—one of the most fertile agricultural regions of the world.八月上旬，乡间田野呈现出一派宁静的景象。春耕播种早已结束，地里的庄稼在茁壮成长，大地充满了微生机。大豆小麦在夏日的骄阳下长势喜人。在７月４日国庆时，玉米还高不没膝，而现在已有六英尺多高了。成群的奶牛和菜牛在绵延起伏的草场上安静地啃食青草，在牧场的中间座落着几栋红色大牲口棚和几幢整洁的白色住房。放眼望去，到处都展现着繁荣的景象。欢迎到中西部来――这里是全世界最富饶的 the result that soil erosion has become a national problem concerning everyone from the farmer to the consumer.但这样的生产力也有基代价。这种集约耕种使土壤受到了自然界破坏力量的侵袭。每年自然界的风和雨水都要从这个国家耕地上带走大量肥沃的土壤，结果土壤侵蚀现已成为一个关系到从农民到消费者每一个人的全国性问题。
职称英语考试《综合类》历年真题精选及答案0513-30
职称英语考试《综合类》历年真题精选及答案0513-301、Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, where increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, including South Korea and Japan.In view of the difficult living and working ______ in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the difficult living conditions often leadto increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.【单选题】A.partsB.conditionsC.methodsD.clothes正确答案:B答案解析:空格所在句的意思是：考虑到中东艰苦的生活和工作条件，用高工资吸引合适的工人也就不奇怪了。

Text OneLoveBy Jesse StuartIntroduction--Jesse Stuart (1907-1984) was the son of an illiterate tenant farmer from eastern Kentucky. He had little formal education as a child. When he finally managed to attend high school, and then college, he discovered his talent for writing and turned out to be a good writer. His short fiction is noted for his great love of nature and his lyrical, simple language. Read the following story.1. Yesterday when the bright sun blazed down on the wilted corn my father and I walked around the edge of the new ground to plan a fence. The cows kept coming through the chestnut oaks on the cliff and running over the young corn. They bit off the tips of the corn and trampled down the stubble.2. My father walked in the cornbalk. Bob, our Collie, walked in front of my father. We heard a ground squirrel whistle down over the bluff among the dead treetops at the clearing’s edge. “Whoop, take him, Bob.” said my father. He lifted up a young stalk of corn, with wilted dried roots, where the ground squirrel had dug it up for the sweet grain of corn left on its tender roots. This has been a dry spring and the corn has kept well in the earth where the grain has sprouted. The ground squirrels love this corn. They dig up rows of it and eat the sweet grains. The young corn stalks are killed and we have to replant the corn.3. I could see my father keep sicking Bob after the ground squirrel. He jumped over the corn rows. He started to run toward the ground squirrel. I, too, started running toward the clearing’s edge where Bob was jumping and barking. The dust flew in tiny swirls behind our feet. There was a big cloud of dust behind us.4. “It’s a big bull blacksnake,”said my father. “Kill him, Bob! Kill him, Bob!”5. Bob was jumping and snapping at the snake so as to 课文一爱杰西·斯图尔特导语：杰西•斯图尔特（1907=1984）出生于美国肯塔基州东部的一个文盲的农民家庭。
2015年职称英语理工类真题Night of the Living Ants
Night of the Living Ants蚂蚁的死亡Whenan ant dies,other ants move the dead insect out of the nest. This behavior isinteresting to scientists,who wonder how ants know for sure—and so soon—that another ant is dead.一只蚂蚁死后，其他蚂蚁会将其移出蚁穴。
这个行为引起了科学家们的兴趣，他们想知道蚂蚁是如何迅速准确地得知有只同伴死了。
Dong-Hwan Choe,a scientist atthe University of California, found that Argentine ants have a chemical on theoutside of their bodies that signals to other ants,“I’m dead—take me away.”加州大学科学家崔东焕发现，阿根廷蚂蚁的身体能向外释放一种化学物质告诉同伴：“我死了，把我搬走吧。
”But there’s a twist to Choe’s discovery.Choe saysthat the living ants—not just the dead ones—have this death chemical.In other words,while an ant crawls around,perhaps in a picnic or home,it’s telling other ants that it’s dead.但崔的发现出现了一个转折。
崔说，不仅仅是死蚂蚁，活蚂蚁也有这种宣告死亡的化学物质。
换句话说，当一只蚂蚁爬来爬去，也许在野餐或者在家，它就在告诉其他蚂蚁，它已经死了。
What keeps ants from haulingaway the living dead?Choe found that Argentine ants have two additionalchemicals on theirbodies,and these tell nearby ants something like,“Wait—I’m not dead yet.”So Choe’s research turned up two sets of chemical signals inants:one says,“I’m dead,”the other set says,“I’m not dead yet.”是什么阻止蚂蚁将发出死亡信号的活蚂蚁拖走呢？崔发现，阿根廷蚂蚁身上还有另外两种化学物质，这两些物质会向周围的蚂蚁传达诸如“等等，我还没死呢”这样的信息。

Unit 4 Living on Your Own课文翻译大学体验英语一
Unit 4 Living on Your OwnPassage A Marcela's Work ExperienceI decided early in my college years that I wanted to experience living abroad before entering in the "real world." During my senior year, while most of my friends were interviewing for "real world" jobs, I was investigating how I could go work in a different country. At that early stage of my inquiry I was pretty open about where to go and what kind of work to undertake. My desire to live abroad was so strong that I was willing to do anything anywhere.Soon I learned about BUNAC, a program that seemed to be designed precisely for students with such interests. BUNAC offers work visas for students or recent graduates to work overseas. Of the six countries available, I chose England because of the language and opportunities for employment.Two months after I graduated from college I crossed the Atlantic. I traveled throughout Europe for six weeks before arriving in London. I got to London on August 24, 1997 with a work visa, but no job or place to live. I have to admit it was pretty scary! The day after I arrived, I experienced my first British holiday-Bank Holiday, a national holiday where everything is closed for the day. It wasn't until my third day that I visited the BUNAC office and went through orientation. At the orientation I learned all about living and working in Britain; I learned about getting around in the city, making a CV (Curriculum Vitae-British resume), paying taxes, getting health insurance, traveling around Britain, finding accommodations and most importantly, finding a job. I was most scared about finding a job since my financial resources were running low and I needed to get a paycheck soon.It turns out that finding a job was just as easy as making a CV! The BUNAC program is very well known in London and many employers participate in the program. As a result there are many employers in many different fields to choose from. My job search began when I chose three different business employers and faxed them my cover letter1 and CV. That first week I had three interviews. I accepted my first offer working for Merrill Lynch International Bank. The Merrill Lynch office I worked at was in a beautiful, old building located two blocks from Buckingham Palace. The people were nice and the work interesting.It was easy to adjust to life in London. And there is so much to see that after six months exploring I probably covered only half of what I intended.Working in London has many advantages. For one, I truly get to learn the culture by being immersed in its workforce. Most of my coworkers were British so I feel like I really got to know and learn the British culture through such a huge aspect of a British person's daily life. Secondly, it is an economical way to live and travel in another country since most jobs pay enough to cover rent, living expenses and some travel expenses. And thirdly, I have the chance to gain valuable work experience and internationalize my resume.Working in London has been the best decision I have made so far. I would not hesitate for a second to recommend it to anyone!A篇玛塞娜的工作经历进大学不久我就下定决心，在进入"现实世界"前先到国外呆一段。

英语晨读文章The art of living
The art of livingThe art of living is to know when to hold fast and when to let go. For life is a paradox: it enjoins us to cling to its many gifts even while it ordains their eventual relinquishment. The rabbis of old put it this way: “A man comes to this world with his fist clenched, but when he dies, his hand is open.”生活的艺术在于懂得什么时候追求，什么时候放弃。
因为生活就是一个矛盾体：它要我们紧紧抓住它赐予我们的生命之礼，然后最终又让它们从我们手中跑掉。
老先生们说：“人们紧握着拳头来到这个世界上，离开这个世界时却摊开了双手。
”Surely we ought to hold fast to life, for it is wondrous, and full of a beauty that breaks through every pore of God’s own earth. We know that this is so, but all too often we recognize this truth only in our backward glance when we remember what was and then suddenly realize that it is no more.当然我们应该紧紧把握生活，因为它美妙得不可思议，充满了从上帝的每个毛孔里蹦出来的美。
我们都清楚这一点，但我们常常只有在回首往事时才会想去过去，才会突然意识到过去永远地消逝了，才会承认这个道理。
2023年高考英语外刊时文精读专题06蟑螂救援队(含答案)
2023年高考英语外刊时文精读精练(6)Roaches to the rescue蟑螂救援队主题语境：人与社会主题语境内容：科学与技术【外刊原文】（斜体单词为超纲词汇，认识即可；下划线单词为课标词汇，需熟记。
）Why go to all the trouble of designing and building a drone（无人机）if nature has already done most of the job for you? That is the attitude taken by the small but determined band of researchers who are trying to robotise（机械化）insects. Some are working on turning insects like beetles（甲虫）into such cyborgs（半人半机器的生物）—perhaps for use in military inspection or spying. Others prefer to concentrate on the fearful side of entomology（昆虫学）,by taking electronic control of cockroaches（蟑螂）.The first cyber-roach（赛博蟑螂） goes back to 1997, when Shimoyama Isao of Tokyo University sent electrical signals to a cockroach's antennae（触角）, causing it to turn either left or right depending on which antenna was stimulated. Others have built on this approach by recruiting extra sense organs, such as the rear-facing cerci（后向尾须）. They have also begun fitting the insects with instrument packs that might let them do a useful job: searching collapsed buildings for survivors.One such is Sato Hirotaka of Nanyang Technological University, in Singapore. He has been working on cyber-insects for 15 years. Now, he has added another twist to cyber-roaches. Instead of having their movements dictated by remote control, his are autonomous agents. They are run by algorithms（算法）that respond directly to sensors in their backpacks.The insects thus fitted out by Dr Sato are Madagascar hissing（发声） cockroaches, which are about 6cm long. The backpacks contain a communications chip, a carbon-dioxide sensor, a motion sensor, an infrared（红外线）camera and a tiny battery.Released into the rubble（碎石）, to crawl their way through while searchingfor signs of life such as movement, body heat and higher CO2 levels from breathing. The artificial intelligence that decides whether a set of signals actually indicate the presence of a human being is programmed directly into the camera. If it thinks it has spotted someone, it alerts a rescuer.To test this arrangement, Dr Sato and his team ran trials in a simulated disaster zone. They laid out concrete blocks of various shapes and sizes in an area of 25 square metres. Among these were a number of people, and also some decoys(诱饵), such as a heat lamp, a microwave oven and a laptop. They then released the cyber-roaches, having first programmed into them the search's start and end points. The software proved able to recognise humans correctly 87% of the time, a success rate Dr Sato thinks could be improved still further by collecting multiple images from different angles. The next phase of the project is to refine the system for use out of doors. That done, manufacture of the backpacks and automation of their attachment (附加装置)to the insects will need to be commercialised（商业化）. If all goes well, Dr Sato predicts the result could be available for use within five years.【课标词汇】1.design设计；制（图）；意图，打算Who designed this building/dress/furniture?是谁设计这座建筑物／这款裙子／这套家俱？This dictionary is designed for advanced learners of English.本词典是为高级英语学习者编写的。
The Nightingale and the Rose综合英语1,课文原文
The Nightingale and the RoseOscar Wilde "She said that she would dance with me if I brought her red roses,"cried the young Student; "but in all my garden there is no red rose."From her nest in the oak tree the Nightingale heard him, and she looked out through the leaves, and wondered."No red rose in all my garden!" he cried, and his beautiful eyes filled with tears. "Ah, on what little things does happiness depend! I have read all that the wise men have written, and all the secrets of philosophy are mine, yet for want of a red rose is my life made wretched.""Here at last is a true lover," said the Nightingale. "Night after night have I sung of him, though I knew him not: night after night have I told his story to the stars, and now I see him. His hair is dark as the hyacinth-blossom, and his lips are red as the rose of his desire; but passion has made his face like pale ivory, and sorrow has set her seal upon his brow.""The Prince gives a ball to-morrow night," murmured the young Student, "and my love will be of the company. If I bring her a red rose she will dance with me till dawn. If I bring her a red rose,I shall hold her in my arms, and she will lean her head upon my shoulder, and her hand will be clasped in mine. But there is no red rose in my garden, so I shall sit lonely, and she will pass me by. She will have no heed of me, and my heart will break.""Here indeed is the true lover," said the Nightingale. "What I sing of, he suffers--what is joy to me, to him is pain. Surely Love is a wonderful thing. It is more precious than emeralds, and dearer than fine opals. Pearls and pomegranates cannot buy it, nor is it set forth in the marketplace. It may not be purchased of the merchants, nor can it be weighed out in the balance for gold.""The musicians will sit in their gallery," said the young Student,"and play upon their stringed instruments, and my love will dance to the sound of the harp and the violin. She will dance so lightly that her feet will not touch the floor, and the courtiers in their gay dresses will throng round her. But with me she will not dance, for I have no red rose to give her"; and he flung himself down on the grass, and buried his face in his hands, and wept."Why is he weeping?" asked a little Green Lizard, as he ran past him with his tail in the air."Why, indeed?" said a Butterfly, who was fluttering about after a sunbeam."Why, indeed?" whispered a Daisy to his neighbor, in a soft, low voice."He is weeping for a red rose," said the Nightingale."For a red rose?" they cried; "how very ridiculous!" and the little Lizard, who was something of a cynic, laughed outright.But the Nightingale understood the secret of the Student's sorrow, and she sat silent in the oak-tree, and thought about the mystery of Love.Suddenly she spread her brown wings for flight, and soared into the air. She passed through the grove like a shadow, and like a shadow she sailed across the garden.In the center of the grass-plot was standing a beautiful Rose-tree, and when she saw it she flew over to it, and lit upon a spray."Give me a red rose," she cried, "and I will sing you my sweetest song."But the Tree shook its head."My roses are white," it answered; "as white as the foam of the sea, and whiter than the snow upon the mountain. But go to my brother who grows round the old sun-dial, and perhaps he will give you what you want."So the Nightingale flew over to the Rose-tree that was growing round the old sun-dial."Give me a red rose," she cried, "and I will sing you my sweetest song."But the Tree shook its head."My roses are yellow," it answered; "as yellow as the hair of the mermaiden who sits upon an amber throne, and yellower than the daffodil that blooms in the meadow before the mower comes with his scythe. But go to my brother who grows beneath the Student's window, and perhaps he will give you what you want."So the Nightingale flew over to the Rose-tree that was growing beneath the Student's window."Give me a red rose," she cried, "and I will sing you my sweetest song."But the Tree shook its head."My roses are red," it answered, "as red as the feet of the dove, and redder than the great fans of coral that wave and wave in the ocean-cavern. But the winter has chilled my veins, and the frost has nipped my buds, and the storm has broken my branches, and I shall have no roses at all this year.""One red rose is all I want," cried the Nightingale, "only one red rose! Is there no way by which I can get it?""There is away," answered the Tree; "but it is so terrible that I dare not tell it to you.""Tell it to me," said the Nightingale, "I am not afraid.""If you want a red rose," said the Tree, "you must build it out of music by moonlight, and stain it with your own heart's-blood. You must sing to me with your breast against a thorn. All night long you must sing to me, and the thorn must pierce your heart, and your life-blood must flow into my veins, and become mine.""Death is a great price to pay for a red rose," cried the Nightingale, "and Life is very dear to all. It is pleasant to sit in the green wood, and to watch the Sun in his chariot of gold, and the Moon in her chariot of pearl. Sweet is the scent of the hawthorn, and sweet are the bluebells that hide in the valley, and the heather that blows on the hill. Yet Love is better than Life, and what is the heart of a bird compared to the heart of a man?"So she spread her brown wings for flight, and soared into the air.She swept over the garden like a shadow, and like a shadow she sailed through the grove.The young Student was still lying on the grass, where she had left him, and the tears were not yet dry in his beautiful eyes."Be happy," cried the Nightingale, "be happy; you shall have your red rose. I will build it out of music by moonlight, and stain it with my own heart's-blood. All that I ask of you in return is that you will be a true lover, for Love is wiser than Philosophy, though she is wise, and mightier than Power, though he is mighty. Flame-coloured are his wings, and coloured like flame is his body. His lips are sweet as honey, and his breath is like frankincense."The Student looked up from the grass, and listened, but he could not understand what the Nightingale was saying to him, for he only knew the things that are written down in books.But the Oak-tree understood, and felt sad, for he was very fond of the little Nightingale who had built her nest in his branches."Sing me one last song," he whispered; "I shall feel very lonely when you are gone."So the Nightingale sang to the Oak-tree, and her voice was like water bubbling from a silver jar.When she had finished her song the Student got up, and pulled a note-book and alead-pencil out of his pocket."She has form," he said to himself, as he walked away through the grove"That cannot be denied to her; but has she got feeling? I am afraid not. In fact, she is like most artists; she is all style, without any sincerity. She would not sacrifice herself for others. She thinks merely of music, and everybody knows that the arts are selfish. Still, it must be admitted that she has some beautiful notes in her voice. What a pity it is that they do not mean anything, or do any practical good." And he went into his room, and lay down on his little pallet-bed, and began to think of his love; and, after a time, he fell asleep.And when the Moon shone in the heavens the Nightingale flew to the Rose-tree, and set her breast against the thorn. All night long she sang with her breast against the thorn, and the cold crystal Moon leaned down and listened. All night long she sang, and the thorn went deeper and deeper into her breast, and her life-blood ebbed away from her.She sang first of the birth of love in the heart of a boy and a girl. And on the top-most spray of the Rose-tree there blossomed a marvellous rose, petal following petal, as song followed song.Pale was it, at first, as the mist that hangs over the river—pale as the feet of the morning, and silver as the wings of the dawn. As the shadow of a rose in a mirror of silver, as the shadow of a rose in a water-pool, so was the rose that blossomed on the topmost spray of the Tree.But the Tree cried to the Nightingale to press closer against the thorn. "Press closer, little Nightingale," cried the Tree, "or the Day will come before the rose is finished."So the Nightingale pressed closer against the thorn, and louder and louder grew her song, for she sang of the birth of passion in the soul of a man and a maid.And a delicate flush of pink came into the leaves of the rose, like the flush in the face of the bridegroom when he kisses the lips of the bride. But the thorn had not yet reached her heart, so the rose's heart remained white, for only a Nightingale's heart's-blood can crimson the heart of a rose.And the Tree cried to the Nightingale to press closer against the thorn. "Press closer, little Nightingale," cried the Tree, "or the Day will come before the rose is finished."So the Nightingale pressed closer against the thorn, and the thorn touched her heart, and a fierce pang of pain shot through her.Bitter, bitter was the pain, and wilder and wilder grew her song,for she sang of the Love that is perfected by Death, of the Love that dies not in the tomb.And the marvellous rose became crimson, like the rose of the eastern sky. Crimson was the girdle of petals, and crimson as a ruby was the heart.But the Nightingale's voice grew fainter, and her little wings began to beat, and a film came over her eyes. Fainter and fainter grew her song, and she felt something choking her in her throat.Then she gave one last burst of music. The white Moon heard it,and she forgot the dawn, and lingered on in the sky. The red rose heard it, and it trembled all over with ecstasy, and opened its petals to the cold morning air. Echo bore it to her purple cavern in the hills, and woke the sleeping shepherds from their dreams.It floated through the reeds of the river, and they carried its message to the sea."Look, look!" cried the Tree, "the rose is finished now"; but the Nightingale made no answer, for she was lying dead in the long grass, with the thorn in her heart.And at noon the Student opened his window and looked out."Why, what a wonderful piece of luck!" he cried; "here is a red rose! I have never seen anyrose like it in all my life. It is so beautiful that I am sure it has a long Latin name"; and he leaned down and plucked it.Then he put on his hat, and ran up to the Professor's house with the rose in his hand.The daughter of the Professor was sitting in the doorway winding blue silk on a reel, and her little dog was lying at her feet."You said that you would dance with me if I brought you a red rose," cried the Student."Here is the reddest rose in all the world. You will wear it to-night next your heart, and as we dance together it will tell you how I love you."But the girl frowned."I am afraid it will not go with my dress," she answered; "and,besides, the Chamberlain's nephew has sent me some real jewels, and everybody knows that jewels cost far more than flowers.""Well, upon my word, you are very ungrateful," said the Student angrily; and he threw the rose into the street, where it fell into the gutter, and a cart-wheel went over it."Ungrateful!" said the girl. "I tell you what, you are very rude;and, after all, who are you? Only a Student. Why, I don't believe you have even got silver buckles to your shoes as the Chamberlain's nephew has"; and she got up from her chair and went into the house."What I a silly thing Love is," said the Student as he walked away."It is not half as useful as Logic, for it does not prove anything,and it is always telling one of things that are not going to happen, and making one believe things that are not true. In fact,it is quite unpractical, and, as in this age to be practical is everything, I shall go back to Philosophy and study Metaphysics."So he returned to his room and pulled out a great dusty book, and began to read.。

We don't know what our stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapon, tools, dyes, medicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of" knowledge " at all.Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct out knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose an apple or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.1.

Not mentionedKey: AABBBABPASSAGE 5A Football ClubDuring the 1970 season, the club played 42 matches: of these, 34 were League and Cup games, and the remainder were friendly matches. In the League, the Club finished in third place, two points behind the champions. Out of 28 League games, 16 were won, 8 were drawn and 4 were lost, whilst the Club managed to reach the semi-final of the Challenge Cup for the first time in its history. Of the eight friendly matches, four were won, two were drawn, and two were lost, but these defeats were at the hands of visiting teams whose standards were generally much higher than those of players of this area.At the same time, the standard of play shown by our own team was markedly superior to that seen in previous years, and this success is largely due to the intensive training programme which has been supervised by the team captain. In this connection, the provision of adequate training facilities must remain a priority, and the erection of an indoor gymnasium or hall in which the players can practise on wet evenings is essential. It would do much to supplement the outdoor training being carried on, and would help the Club in the recruitment of younger players.There are now 28 players registered with the Club, and many more have asked to join but have been discouraged by the fact that the Club fields only one team. With the improvement in the financial position, concerning which the Treasurer will report in a minute. I suggest that the Committee consider entering a team in the Second Division of the League.1. How many Cup matches did the Challenge Club play?A) 34B) 6C) 8D) 422. What reason does the speaker give for the Club's improved playing record?A) The provision of adequate training facilities.B) The erection of an indoor gymnasium.C) The intensive training under the team captain.D) The low standards of the visiting teams.3. In the second paragraph," this connection" refers toA) an indoor gymnasium.B) An indoor hall.C) The team captain.D) The intensive training programs.4. The committee may enter a team in the Second Division of the League because ofA) its improved financial position.B) Its better training facilities.C) Its improved playing record.D) Its ambition to become famous.5.

2010年职称英语考试(理工类)新增阅读理解--书中第38篇第38篇 Night1 of the Living AntsWhen an ant dies, other ants move the dead insect out of the nest. This behav ior is interesting to scientists, who wonder how ants know for sure – and so soon-that another ant is dead.Dong-Hwan Choe, a scientist at the University of California2 found that Arg entine3 ants have a chemical on the outside of their bodies that signals to other ants, "I 'm dead - take me away."But there's a twist to Choe's discovery4. These ants are a little bit like zombie s. Choe says that the living ants - not just the dead ones - have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it's telling other ants that it's dead5.What keeps ants from hauling away the living dead? Choe found that Argenti ne ants have two additional chemicals on their bodies, and these tell nearby ants some thing like, "wait -I'm not dead yet. "So Choe's research turned up6 two sets of chemic al signals in ants: one says, "I'm dead," the other set says, "I'm not dead yet."Other scientists have tried to figure out how ants know when another ant is d ead. If an ant is knocked unconscious, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.Choe suspects that when an Argentine ant dies, the chemical that says "Wait- I'm not dead yet" quickly goes away. Once that chemical is gone, only the one that sa ys "I'm dead" is left." It's because the dead ant no longer smells like a living ant that itgets carded to the graveyard, not because its body releases new unique chemicals afte r death," said Choe. When other ants detect the "dead" chemical without the "not dead yet" chemical, they haul away the body. This was Choe's hypothesis.To test his hypothesis, Choe and his team put different chemicals on Argenti ne ant pupae. When the scientists used the "I'm dead" chemical, other ants quickly hau led the treated pupae7 away. When the scientists used the "Wait- I'm not dead yet" ch emicals, other ants left the treated pupae alone. Choe believes this behavior shows tha t the "not dead yet" chemicals override the "dead" chemical when picked up by adult a nts. And that when an ant dies, the "not dead yet" chemicals fade away. Other nearby ants then detect the remaining "dead" chemical and remove the body from the nest.词汇：Zombie n 还魂尸，僵尸 Pupa n.蛹Graveyard n.墓地hypothesis n.假设override v.优先于，比……更重要注释：1. night：night 是个多义词，其比喻意义是“死亡”，即本篇短文标题中该词的意思。

At railroad crossings, flashing red lights warn cars to stay back. A red light at a traffic intersection tells cars to stop, so A they don't run into other cars.In the future, the color red also may help prevent danger C at construction sites. Thanks to new work by engineers, bridge supports- or other kinds of materials—could one day contain a color-changing material. It will turn red A before a structure collapses or falls D apart A tiny molecule may make a big difference in future warning systems.A polymer C containing a color-changing molecule called a mechanophore turns red seconds before it snaps. The technology may one day allow damage to materials or structures to be easilyB spotted .The secret behind the color-changing material is a particular type of molecule. A molecule is a group of atoms held together by D chemical bonds. Molecules come in all shapes and sizes, and make up A everything you can see, touch or feel. How a molecule behaves depends on whatkinds of atoms it contains, and how they're held together.When a polymer containing a color-changing moleculecalled a mechanophore is about to breaks, it produces acolor. When a polymer with mechanophore moleculesbecomes "injured" or A weak , one of themechanophore bonds breaks and the material turns red. "It'sa really simple detection method," says Nancy Sottos, oneof the scientists who worked on the project."We're B opening up this one bond, and it changescolor. " Sottos and her team tested the color-changingpolymers in their lab. The test D results provedencouraging.There is a way to get rid of the red color: C light .When a bright light is shone on the mechanophore, thebroken bond is fixed - and the red color disappears. This"self-healing" may be a problem for engineers. They need touse the color-changer in big construction projects that willbe D outside , in sunlight. And sunlight will make themechanophore's warning system useless.Sottos and her fellow scientists still have D a lot of workto do before the color-changing molecules can be usedoutside the lab.第12篇 The Case of the Disappearing Fingerprints（完形填空）One useful anti-cancer drug can effectively erasethe whorls and other characteristic marks that givepeople their distinctive fingerprints. Losing Bthem become troublesome. A case released online ina letter by Annals of Oncology indicates how big aD problem of losing fingerprints is.Eng-Huat Tan, a Singapore-based medical doctordescribes a 62-year old man who has usedcapecitabine1 to A treat his nasopharyngeal cancer.After three years on the C drug, the patient decidedto visit U.S. relatives last December. But he wasstopped by U.S. customs officials C for4 hours afterentering the country when those officials couldn'tget fingerprints from the man. There were nodistinctive swirly B marks appearing from his indexfinger2.U.S. customs3 has been fingerprintingincoming foreign visitors for years, Tan says. Theirindex fingers are A printed and screened againstdigital files of the fingerprints of bad guys --terrorists and potential criminals that our federalguardians have been tasked with keeping out of thecountry4. Unfortunately, for the Singaporetravelers, one potential D side effect of his drugtreatmerit is a smoothing of the tissue on the fingerpads6. B Hence , no fingerprints."It is uncertain when fingerprint loss will Abegin to take place in patients who are takingcapecitabine," Tan points out. So he cautions anyphysicians who D prescribe the drug to provide theirpatients with a doctor's note pointing out thattheir medicine may cause fingerprints to disappear.Eventually, the Singapore traveler made it intothe United States7. I guess the name on his passportdidn't raise any red flags8. But he's also now gotthe explanatory doctor's note – and won't leavehome C without it.By the way, maybe the Food and DrugAdministration9, D which approved use of the drug11 years ago, should consider A updating its list of side effects associated with this medicine. The current list does note10 that patients may experience vomiting, stomach pain and some other side effects. But no whereB does it mention the potential for loss of fingerprints.第十五篇 Obtaining Drinking Water from Air Humidity (A级)（完形填空）Not a plant to be seen, the desert ground is too 1 . But the air contains water, and research scientists have found a 2 of obtaining drinking water from air humidity. The system is based completely on renewable energy and is therefore autonomous.Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water. But even here, where there are no lakes, rivers or groundwater, considerable quantities of water are stored in the air. In the Negev desert in Israel, for example, annual average relative air humidity is 64 percent -- in every cubic meter of air there are 11.5 milliliters of water.German research scientists have found a way of converting this air humidity autonomously into drinkable water. "The process we have developed is based exclusively on renewable energy sources such as thermal 3 collectors and photovoltaic cells, which makes this method completely energy-autonomous. It will therefore function in regions 4 there is no electrical infrastructure," says Siegfried Egner, head of theresearch team. The principle of the 5 is asfollows: hygroscopic brine —saline solutionwhich absorbs moisture — runs down a tower-shapedunit and absorbs water from the air. It is thensucked into a tank a few meters 6 the groundin which a vacuum prevails. Energy from solarcollectors heats up the brine,, which is diluted bythe water it has 7Because of the vacuum, the boiling point of theliquid is 8 than it would be under normalatmospheric pressure. This effect is known from themountains: as the atmospheric pressure 9 islower than in the valley, water boils attemperatures 10 below 100℃. Theevaporated, non-saline water is condensed and runsdown through a completely filled tube in acontrolled manner. The gravity of this water columncontinuously produces the vacuum and so a vacuumpump is not needed. The reconcentrated brine runsdown the tower surface 11 to absorbmoisture from the air."The concept is suitable for variouswater 12 Single-person units andplants 13 water to entire hotels areconceivable," says Egner. Prototypes have beenbuilt for both system components-air moistureabsorption and vacuum evaporation-and the researchscientists have already 14 their interplay on alaboratory scale.

In New York there's always something being built.And everything goes up so quickly…you never know what's going to be around next week.Roberto: Yea, but on the other hand, sometimes I wonder about overcrowding. Maybe they need to start building down more. Takeshi: Building down?Roberto: Yeah, it's when you build underground instead of above ground. Takeshi: Nah, that's too much like living in a cave. I love the skyscrapers!They are the most incredible feats of engineering!Roberto: True. And some of the first ones were built right here in New York City.Takeshi: That's right! You know, I wonder what New York looked like before all these building popped up.Roberto: I don't know, but I'd like to see this one when it's finished. Takeshi: Yeah. I'll bet it'll be something fantastic!Roberto: Maybe…what do you think it's going to look like?Takeshi: I don't know…but you know what? I'm going to remember what it looked like.Roberto: What are you talking about? And why are you taking pictures?There's nothing there.Takeshi: OK. You know some people get famous because they have pictures of movie stars or performers before they make it big?Roberto: Yeah?Takeshi: Well, some building and architectural structures get to be famous too, like the Eiffel Tower or the Empire State Building…right? Roberto: Yeah, and…? There's nothing here!Takeshi: Right! But there will be. Someday this very spot may become really well-known —like maybe it'll be some incredible hotel that the rich and famous stay at. And I'll be the only one with pictures of it before it was built. Cool, huh?Roberto: Uh…you are too much. Hey, let's ask this guy what your “famous”building’s going to be. Excuse us, can you tell us what this is going to be when it's finished? Maybe a fancy hotel orsomething?Construction Worker: Fancy hotel? No, this isn't going to be a hotel. It's going to be a parking garage.Roberto: A parking garage. Uh …huh. Thanks.Takeshi: Well…maybe…someone rich and famous will park here.第二单元：City Living The first word processorMrs. Morgan: Good. So change the first part and make those corrections and your paper will be great.Tara: Ok. Thanks for all your help, Professor Morgan. I'll email my paper to you later today.Mrs. Morgan: You know technology is amazing. In high school I used to write my papers on a typewriter.Tara: It must have taken a long time to write a paper on a typewriter. Mrs. Morgan: Well, I was pretty fast, but I hade some mistakes. Actually the typewriters weren’t that bad. Now as for the first computer…oh my gosh!Tara: What do you mean?Mrs. Morgan: The first computers were so unreliable. They used to crash all the time. And they were not as affordable or as fast as they are now. Tara: Mine's pretty fast, but not as fast as some of the newer, more expensive ones.Mrs. Morgan: I know! And nowadays, almost everyone has a computer. In those days, nobody had their own computer. We had to use the ones at the university.Tara: In the computer lab?Mrs. Morgan: Yeah, that's all we had. I'll never forget, one spring, during final exams. Everybody was working on their term papers, and theelectricity went out!Tara: So? No big deal…laptops have batteries…Mrs. Morgan: Yes, but remember, in those days we didn't have laptops. If your computer crashed, you lost everything.Tara: Everything?Mrs. Morgan: Everything. We used to lose information all the time, but that time it was terrible. Everybody lost their paper that afternoon…including me.Tara: What did you do?Mrs. Morgan: I went back to the good, old-fashioned wayTara: You mean typewriter?Mrs. Morgan: Nope.
