It was open twenty-four hours a day, seven days a week.My first job was shining shoes for customers when I was six years old. My duties increased as Igrew older. By age ten I was clearing tables and washing plates. My father made it clear that I hadto meet certain standards. I had to be on time, hard-working and polite to the customers. I wasnever paid for any work I did. One day I made the mistake of telling Dad I thought he should giveme ten pounds a week. He said, "OK, then how about you paying me for the three meals a daywhen you eat here and for the times you bring your friends here for free drinks?" He figured Iowed him about 40 pounds a week. This taught me quite a lot.________________________________________Unit 2Part BText 1Exercise 1: 1. b 2. a 3. d 4. cExercise 2:1984 / son / medical school / tuition / afford it / realize / newspaper ads / extra business /advertisement / succeeded / agent / changed / phone call / put aside / doing / immediately /familiar / father-in-law's / visited / his father-in-law alive / coincidence.Text 2Exercise 1: 1.

TPART DUnexplained ParallelsOne of the best-known collections of parallels is between the careers of Abraham Lincoln and John F. Kennedy. Both were shot on a Friday, in the presence of their wives; both were succeeded by a Southerner named Johnson; both their killers were themselves killed before they could be brought to justice. Lincoln had a secretary called Kennedy; Kennedy a secretary called Lincoln. Lincoln was killed in the Ford Theater; Kennedy met his death while riding in a Lincoln convertible made by the Ford Motor Company -- and so on.Similar coincidences often occur between twins. A news story from Finland reported of two 70-year-old twin brothers dying two hours apart in separate accidents, with both being hit by trucks while crossing the same road on bicycles. According to the police, the second victim could not have known about his brother's death, as officers had only managed to identify the first victim minutes before the second accident.Connections are also found between identical twins who have been separated at birth. Dorothy Lowe and Bridget Harrison were separated in 1945, and did not meet until 1979, when they were flown over from Britain for an investigation by a psychologist at the University of Minnesota. (8处答案为met,34)They found that when they met they were both wearing seven rings on their hands, two bracelets on one wrist, a watch and a bracelet on the other. They married on the same day, had worn identical wedding dresses and carried the same flowers. Dorothy had named her son Richard Andrew and her daughter Catherine Louise; Bridget had named her son Andrew Richard and her daughter Karen Louise.(10处答案similar自己看下这个不一定, children) In fact, she had wanted to call her Catherine. Both had a cat called Tiger. They also had a string of similar mannerisms when they were nervous.How can we explain the above similarities?________________________________________Unit 3Part BText 1Exercise 1: 1. b 2. c 3.aExercise 2:1. Because she wanted to understand each other's expectations so that potential problems could be avoided and they could live happily together.2. Cleaning up. Everything must be cleaned up and put away before going to bed.3. Sleeping. Time for bed: 11pm; time to get up: 6:30am except on weekends.Text 2Exercise 1: 1. F 2.F 3.T 4.TExercise 2:1. One rule says that if they get lost for more than five minutes when they are driving, they must stop and ask for directions.2. Once Tom and Linda got lost when they were driving to a friend's wedding.3. Linda wanted to stop at a gas station to ask the way, but Tom thought he could figure it out.4. As a result, they were late for the wedding because they went in the wrong direction for forty miles.Part C1. ...not so special/not extremes2. a. ...get angry quickly b. ...change themselves...PART D原文Husbands and Wives Don't See Things AlikeLet's face it -- husbands and wives just don't see things alike. Take TV remote controls, for example. I'm a channel-grazer. When I watch the news, I flip back and forth through four different networks."It drives me crazy when you do that," my wife complains. I don't understand why she has no interest in other channels. After all, she is a woman who wants to know everything going on in the neighborhood and among all the relatives. Just one button away might be an interesting program on How to Lose Fifty Pounds by Eating Chocolate Sundaes or How to Understand Weird Husbands. But, no, she won't change channels, not even if she dislikes the program she's watching."This talk show host makes me so angry!" she cried one evening."Then why don't you change the channel?" I asked."Because I can't stand people who are always changing channels."Differences. No right or wrong, just differences."The first law of civilization," said an old philosopher, "is to let people be different."I don't need to convert my wife to my ways, and she doesn't try to make me be like her. We simply take turns monitoring the remote control.1. The major difference between the speaker and his wife is their TV viewing habits.2. According to the speaker, he is more interested in talk shows while his wife is more interested in news programs.3. The wife seems to be more weird than the husband is.4. The speaker and his wife usually take turns working the remote control when they watch television.5. It can be inferred that women are generally more tolerant than men of their spouse's differences.6. The speaker and his wife maintain peace not by changing each other but by tolerance.________________________________________Unit 4Part BText 1Exercise 1: 1. d 2. c 3.aExercise 2:Sam has been a police officer for 30 years. He has done everything from patrol to undercover work. He has also done detective work and now he is supervising investigations.Sam thinks being a police officer is a very stressful job, but it depends on the assignment one has. In his opinion the biggest pert of the stress is the fear of the unknown and patrol is the most stressful assignment.Text 2Exercise 1: 1. T 2. F 3. T 4. F 5. TExercise 2:1. ...

Few people may realize, however, that painting the walls, knitting bedspreads or sewing pillows can help relieve the life pressures we all experience.Studies indicate that engaging in creative endeavors such as sewing and crafting can lower one's risk of stroke, kidney damage and heart disease.These calming, repetitive activities relax the mind and can lower blood pressure. Sharing such activities can also be a way to spend time with loved ones, which increases our sense of belonging and further reduces stress.People have always turned to working with their hands in times of stress. Handicraft works, with their symbols of hope, have a far greater impact when created by groups.Keep in mind the following tips to increase the stress-relieving benefits of your craft projects:1. Work with materials that stimulate the senses; work in a comfortable area without distractions; play your favorite music.2.(4处答案framing) Make a family project of selecting your favorite photos, and frame them so they can be enjoyed every day. In stressful times, the photos can lift your spirits as you recall happy moments.3. If your schedule is hectic, choose a practical project that will make the most of crafting time. Ifa simple kitchen curtain needs to be replaced, start there.Change sometimes compels us to see things in new ways.________________________________________Unit 5Part BText 1Exercise 1: 1. D 2.

What's wrong?Jenny: Well, Roger, I've got a problem.Roger: What is it?Jenny: You know my daughter Jane is 16 years old now. And we've begun talking about college. She says she wants to go, but she's let her grades slip and no matter how I urge her to study, all she seems interested in are clothes and boys. We're not wealthy, you know. And it won't be easy for us to afford the tuition if she can't get a scholarship. Is going to college the best choice for her right now?Roger: Do you mean that she doesn't seem ready for college?Jenny: You're right.Roger: Then you'd better have a serious talk with Jane about college.Jenny: A serious talk with her?Roger: Yes, to my mind it's quite normal for girls her age to be wrapped up in fashion and dating, but as a mother you have a right to expect her to pay attention to her studies too.Jenny: Yes, but how?Roger: Ask her how serious she is about college and how hard she's willing to work for it. Jane may be more committed than you realize. But if not, tell her she should think about putting collegeoff for a while. That could give her the push she needs to take her education seriously.Jenny: Sounds like a good idea.Roger: And if you decide she should wait, she can get a job, take classes at a community college or do an internship to get experience. She may be just one of those who need to see a bit of real life before they settle down.________________________________________Unit 6Part BText 1Exercise 1: 1. D 2. CExercise 2:Leaves are Nature's food factories. Plants take water from the ground through their roots and carbon dioxide from the air. Then leaves turn water and carbon dioxide into sugar in the presence of sunlight and chlorophyll. This process is called photosynthesis. Leaves are mostly green because chlorophyll is green. As a matter of fact, there are, in leaves, small amounts of yellow and orange all along, but they are covered up by the green chlorophyll in summer. They show up in fall as chlorophyll disappears from the leaves, due to the decline of photosynthesis. The bright reds and purples we see in leaves of trees like maples are made mostly in fall. The brown color of trees like oaks is made from wastes left in the leaves.Text 2Exercise 1: 1. C 2. BExercise 2:1. They are leaf pigments, length of night, and weather.2. It is the steadily increasing length of night.3. They change their colors at the same time no matter whether they are on a high mountain or in warm lowlands because the timing of color change seems to be genetically inherited.4. It is because their needle-like or scale-like foliage is covered with a heavy wax coating and the liquid inside their cells contains cold-resistant elements.5. In the Arctic because the winter there is too cold.Part CExercise: 1. T 2.F 3.T 4.T 5.F 6.F 7.T 8.TPart D答案Where,原文For years Mr. Urquhart and his colleagues wondered where the migratory monarchs spent the winter. (第3、4空答案mystery仅供参考，his colleagues wondered)Despite their hopes, fieldwork in Florida and along the Gulf Coast discovered no large groups of wintering monarchs. Then in late 1972, his wife Norah wrote to newspapers in Mexico about the project, asking for volunteers to report sightings of the butterfly and help with tagging. Finally, in response came a letter, dated February 26, 1973, from a man called Kenneth Brugger in Mexico City, who offered to help find the butterfly hideaway.Traveling in his motor home, Brugger drove back and forth across the Mexican countryside, looking for clues. He was especially watchful at dusk, when the butterflies would be moving about looking for a place to sleep.At last, one day was successful. On the evening of January 9, 1975, Brugger called fromMexico. "I have found them -- millions of monarchs -- in evergreens beside a mountain clearing," he said, unable to control the excitement in his voice.High in a range of volcanic mountains that crosses central Mexico, he came upon hundreds of evergreen trees, each entirely hidden by sleeping butterflies. Some of the insects wore tags that Mr. Urquhart and his helpers had put on them in Canada and the northern United States. The mystery was solved! The monarchs' winter home is well suited to their needs. Throughout the winter the temperature stays near freezing. It is not cold enough to kill the visiting insects, but it is chilly enough to keep them from moving about. The butterflies survive on the stored fat from their summer foods.In spring the butterflies awaken and fly north again. Tagged butterflies, which were marked in Mexico, have been found in the United States.So one mystery is solved. But another remains. How do the butterflies find their way? Those that migrate south in the fall were born sometime during the summer or early fall. They have never been to Mexico. Yet they somehow seek out the same resting places. The mystery of how they find their way is left for future scientists to solve.________________________________________。

Exercise 1

Exercise 11. An electric power distributor charges residential customers $0.10 per kilowatt-hour (kWh). The company advertises that “green power” is available in 150kWh blocks for an additional $4 per month. (Green power is generated from solar, wind power, and methane sources.)a.If a certain customer uses an average of 400 kWh per month and commits to one monthly 150 kWhblock of green power, what is her annual power bill?b.What is the average cost per kWh with green power during the year>c.Why does green power cost more than conventional power?2. Six years ago, an 80-kW diesel electric set cost $160,000. The cost index for this class of equipment six years ago was 187 and now is 194. The cost-capacity factor is 0.6.a.The plant engineering staff is considering a 120-kW unit of the same general design to power asmall isolated plant. Assume we want to add a precompressor, which (when isolated and estimate separately) currently costs $18,000. Determine the total cost of the 120-kW unit.b.Estimate the cost of a 40-kW unit of the same general design. Include the cost of the $18,000precompressor.3. The structural engineering design section within the engineering department of a regional electrical designs for a group of similar transmission line towers. The detailed design of each tower is based on one of the standard designs. A transmission line project involving 50 towers has been approved. The estimated number of engineering hours needed to accomplish the first detailed tower design is 126. Assuming a 95% learning curve,a.What is your estimate of the number if engineering hours needed to design the eighth tower and todesign the last tower in the project?b.What is your estimate of the cumulative average hours required for the first five designs?4. You have been asked to estimate the cost of 100 prefabricated structures to be sold to a local school district. Each structure provides 1,000 square feet of floor space, with 8-feet ceilings. In 1999, you produced 70 similar structures consisting of the same materials and having the same ceiling height, but each provided only 800 square feet of floor space. The material cost for each structure as $25,000 in 1999, and cost capacity factor is 0.65. The cost index values for 1999 and 2006 are 200 and 289, respectively. The estimated manufacturing cost for the first 1,000-square-foot structure is $12,000. Assume a learning curve of 88% and use the cost of 50th structure as your standard time for estimating manufacturing cost. Estimate the total material cost and the total manufacturing cost for the prefabricated structures.5. Consider the following loan information and repayment table:Loan principal=$10,000Interest rate=8% per yearDuration of loan=3 yearsAnnual payment=$3,880EOY k Interest Paid Principal Repayment1 $800 ?2 $553.60 $3,326.403 ? ?6. A lump-sum loan of $5,000 is needed by Chandra to pay for college expenses. She has obtained small consumer loans with 12% interest per year in the past to help pay for college .But her father has advised Chandra to apply for a PLUS student loan charging only 8.5% interest per year. If the loan will be repaid in full in five years, what is the difference in total interest accumulated by these two types of student loans?7. A credit card company wants your business. If you accept their offer and use their card, they will deposit 1% of your monetary transactions into a savings account that will earn a guaranteed 5% per year. If your annual transactions total an average of $20,000, how much will you have in this savings plan after 15 years?8. Liam O’Kelly is 20 years old and is thinking about buying a term life insurance policy with his wife as the beneficiary. The quoted annual premium for Liam is $8.48 per thousand dollars of insurance coverage. Because Liam wants a $100,000 policy ( which is 2.5 times his annual salary ), the annual premium would be $848, with the first payment due immediately (i.e., at age 21). A friend of Liam’s suggests that the $848 annual premium should be deposited in a good mutual fund rather than in the insurance policy. “If the mutual fund earns 10% per year, you can become a millionaire by the time you retire at age 65,”the friend advises.a.Is the friend’s statement really true?b.Discuss the trade-off that Liam is making if he decides to invest his money in a mutual fund.9. Twelve payments of $10,000 each are to be repaid monthly at the end of each month .The monthly interest rate is 2%.a.What is the present equivalent (i.e., P0) of these payments?b.Repeat Part (a) when the payments are made at the beginning of the month .Note that the presentequivalent will be at the same time as the first monthly payment.c.Explain why the present equivalent amounts in Parts (a) (b) are different.10. Automobiles of the future will most likely be manufactured largely with carbon fibers made from recycled plastics, wood pulp, and cellulose. Replacing half the ferrous metals in current automobiles could reduce a vehicle’s weight by 60% and fuel consumption by 30%. One impediment to using carbon fibers in cars is cost. If the justification for the extra sticker price of carbon-fiber cars is solely based on fuel savings, how much extra sticker price can be justified over a six-year life span if the carbon-fiber car would average 39 miles per gallon lf gasoline compared to a conventional car averaging 30 miles per gallon ? Assume that gasoline costs $3.00 per gallon, the interest rate is 20% per year, and 117,000 miles are driven uniformly over six years.。

4. The Fourier series is a particular type of orthogonal series representation that is very useful in solving engineering problems, especial communication problems. The orthogonal functions that are used are either sinusoids, or, equivalently, complex exponential functions.傅立叶级数是一种特殊类型的正交级数表示，它在解决工程问题，特别是通信问题时，十分有用。

它所利用的正交函数是正弦函数或等价的复指数函数5. For periodic waveforms, the Fourier series representations are valid over all time. Consequently, the (two-side) spectrum, which depends on the waveshape from t=–∞to t=∞, may be evaluated in terms of Fourier coefficients.对于周期波形，傅立叶级数表示法在整个时间段都是有效的。

因此，可以根据傅立叶系数，计算取决于t=–∞到t=∞之间波形的(双边)频谱。

4. It should be clear that the spectrum of a voltage (or current) waveform is obtained by a mathematical calculation and that it does not appear physically in an actual circuit. f is just a parameter (called frequency) that determines which point of the spectral function is to be evaluated.应该清楚，电压（或电流）波形的频谱是通过数学计算获得的，并不从物理上出现于实际的电路中。

(part one)andrew had always wanted to be a doctor. but the tuition for a medical school in 1984 was 15,000 dollars a year, which was more than his family could afford. to help him realize his dream, his father, mr. stewart, a real estate agent, began searching the house-for-sale ads in newspapers in order to find extra business. one advertisement that he noted down was for the sale of a house in a nearby town. mr. stewart called the owner, trying to persuade him to let him be his agent. somehow he succeeded and the owner promised that he would come to him if he failed to get a good deal with his present agent. then they made an appointment to meet and discuss the thing.as good things are never easy to acquire, the time for the appointment had to be changed almost ten times. on the day when they were supposed to meet at 3 oclock in the afternoon, mr. stewart received another call from the owner. his heart sank as he feared there would be another change of time. and so it was. the owner told him that he couldnt make it at three but if he would come right then, they could talk it over. mr. stewart was overjoyed. leaving everything aside, he immediately set out todrive to the house.as he approached the area, he had a strange feeling of having been there before. the streets, the trees, the neighborhood, all looked familiar to him. and when he finally reached the house, something clicked in his mind. it used to be the house of his father-in-law! the old man had died fifteen years ago but when he was alive, he had often visited him with his wife and children. he remembered that, like his son andrew, his father-in-law had also wanted to study medicine and, failing to do so, had always hoped that one of his two daughters or his grandchildren could someday become a doctor. exercise 1:1. b 2. a 3. d 4. cquestions:1. who are the two main characters in the story you have just heard?2. how did mr. stewart get to know the owner of the house?3. what problem did mr. stewart have?4. what is the coincidence in the story you have just heard?exercise 2:1984 / son / medical school / tuition / afford it / realize / newspaper ads / extra business / advertisement / succeeded / agent / changed / phone call / put aside / doing / immediately / familiar / father-in-laws / visited / his father-in-law alive / coincidence text2what a coincidence! (part two)when he entered the house, mr. stewart was even more amazed to find that the house was decorated exactly as he had remembered it. he told the owner about this and the latter became intrigued too. however, they were in for even greater surprises. it so happened that in the middle of their discussion, a postman came to deliver a letter. and the letter was addressed to mr. stewarts father-in-law! were it not for mr. stewarts presence there and then, the letter would be returned as no person of that name lived in the house any longer. as the postman demanded a signature on the receipt slip, mr. stewart signed for his long-deceased father-in-law. mystified, the owner urged mr. stewart to open the letter and see what it contained. the letter was from a bank. when he opened it, two words immediately met his eye -- for education. it was a bank statement of an amount his father-in-law had put in years ago for his grandchildrens education needs. with the interest it had earned over the years, the standing value of the amount came to a little over $15,000, just enough money to cover the tuition of andrews first year at a medical college!another thing that is worth mentioning is about the postman. the original postman, who had worked in this neighborhood, called in sick that day. so the postman, who was new to the area, came to deliver mail in his place. had it been the old postman, the letter would undoubtedly be returned to the sender as he knew full well that no person bearing that name lived in that house any longer.the miracle was a blessing for andrew. with the money givento him by his grandfather he was able to study medicine. now he is a doctor in illinois.exercise1：1. the house was decorated exactly the same as mr. stewart remembered it2. mr. stewart happened to be in the house when a postman came to deliver a letterto his father-in-law who had died 15 years ago.3. the old postman had called in sick that day, and the postman who came in hisplace was not familiar with the neighborhood. other wise the letter would have been returned to its sender.exercise 2:1. he was intrigued.2. a bank statement.3. his father-in-law had put an amount of money in the bankfor his grandchildrens education.4. a little over $15,000.5. he could use the money to cover the tuition of his first year at a medical college.6. he is a doctor in illinois.unit 3text 1krimali (part one)on the morning of the devastating earthquake that struck india in 2001, krimali, a girl of 17, had just left home to go to an interview for a position of a sales clerk. she was pleased with her green and yellow flowered dress, but felt something wasnt quite right about her hair. she returned home, removing her shoes and leaving them at the door.moments later, the earthquake struck. ceilings and walls in the building shook in the deafening noise. then everything began crashing down.krimali and her immediate family escaped serious injury but were unable to make their way out. the ceiling of an entire room towered above the only possible escape route. completely detached on three sides, the huge slab clung to an outside wall on its fourth side. to an observer, it could drop at any moment.people were screaming and didnt know what to do. krimali decided to act. carefully she climbed barefoot up and down the debris until she reached a point just beneath the swaying ceiling. about four meters below were uneven pieces of concrete, broken glass and smashed furniture, all mixed with sharp spikes of iron. she knew if she could manage to getdown to the ground level, she could make her way to safety. she paused to figure out the best way down. as there wasnt any good place to jump, she just jumped. luckily, she landed in a crouch, her feet missing any sharp edges. emboldened by her good fortune, krimali knew it was up to her to persuade others to follow.exercise 1: ex 1 1-2 c c ex 2 1-8 t f f f f t t ftext 2krimali ( part two)krimali planned to rescue her family first, but just then she heard a woman from two storeys above screaming for someone to save her two-month-old baby.throw the baby to me, krimali shouted. i can catch her!the woman refused. krimali told the woman to wrap the babyin bed sheets and then toss her down. crying uncontrollably, the mother wrapped the little girl but stillwould not part with her baby. as the mother tried to decide what to do, krimali intently watched the concrete ceiling hanging above her. finally the mother tossed the baby. krimali made a clean catch. a bright smile lit up the womans face. ill be back! krimali called out, hugging the child to her as she hurriedly picked her way out to where survivors had gathered. she gave up the baby, then asked if any of the men there would come back with her to help others trapped in the building. no one came forward, for they were all afraid of that swaying ceiling. but for krimali, a small girl of 154 centimeters in height and weighing about 50 kilos, her fears had been lifted by what she had accomplished.on her way back into the ruins, she saw part of a large door. it was extremely heavy but she managed to drag it to the spot just below the hanging ceiling. by placing it on the ruins, she created something like a sliding board. with krimali coaching her, the babys mother partly jumped and partly rolled down the board to the ground level. krimali led her through the debris to her baby.in the hours that followed krimali made countless rescue missions into the building, each time in the shadow of the huge ceiling. thanks to her courage, about two dozen men, women and children were saved.exercise 1:questions :1-2 d bexercise 2:1. because she was afraid krimali might not be able to catch her.2. because she thought the bed sheets could somehowprotect the baby from being hurt if she failed to catch her.3. because they were afraid of the swaying ceiling.4. to make it easier and safer for people to get down.5. about two dozen were saved.unit 4text 1a marriage agreement (part one)(tom and linda have signed a marriage agreement. both agree not to break the rules outlined in the agreement. john, a reporter, is talking to them about the agreement.) john: tom, linda, first id like to ask you why you decided to write this unusual agreement.tom: we found that many problems are caused when a person has different expectations from his or her spouse. we wantedto talk about everything openly and honestly before we started living together.linda: also we both know how important it is to respect each others pet peeves. like, i can get very annoyed if others leave stuff -- clothing, papers, everything!
