My First Job

My parents ran a small restaurant. It was open twenty-four hours a day, seven days a week. My first job was shining shoes for cus tomers when I was six years old. My duties increased as I grew ol der. By age ten I was clearing tables and washing plates. My fathe r made it clear that I had to meet certain standards. I had to be o n time, hard-working and polite to the customers. I was never paid for any work I did. One day I made the mistake of telling Dad I thought he should give me ten pounds a week. He said, "OK, the n how about you paying me for the three meals a day when you e at here and for the times you bring your friends here for free drin ks?" He figured I owed him about 40 pounds a week. This taught

me quite a lot.

Unexplained Parallels

One of the best-known collections of parallels is between the car

eers 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 kill ed 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 fr om Finland reported of two 70-year-old twin brothers dying two ho urs apart in separate accidents, with both being hit by trucks while crossing the same road on bicycles. According to the police, the s econd victim could not have known about his brother's death, as of ficers had only managed to identify the first victim minutes before

the second accident.

Connections are also found between identical twins who have be en separated at birth. Dorothy Lowe and Bridget Harrison were sep arated in 1945, and did not meet until 1979, when they were flown over from Britain for an investigation by a psychologist at the Un iversity of Minnesota. (8处答案为met,34)They found that when the y met they were both wearing seven rings on their hands, two brac elets on one wrist, a watch and a bracelet on the other. They marri

ed on the same day, had worn identical wedding dresses and carrie d the same flowers. Dorothy had named her son Richard Andrew a nd her daughter Catherine Louise; Bridget had named her son Andr ew 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 Catheri ne. 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?

原文

Husbands and Wives Don't See Things Alike Let's face it -- husbands and wives just don't see things alike. T ake TV remote controls, for example. I'm a channel-grazer. When I watch the news, I flip back and forth through four different netwo

rks.

"It drives me crazy when you do that," my wife complains. I d

on'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 n eighborhood and among all the relatives. Just one button away mig ht be an interesting program on How to Lose Fifty Pounds by Eati ng Chocolate Sundaes or How to Understand Weird Husbands. But, no, she won't change channels, not even if she dislikes the progra

m she's watching.

"This talk show host makes me so angry!" she cried one evenin

g.

"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 tr y to make me be like her. We simply take turns monitoring the re

mote control.

PART D

Finding Creative Outlets for Very Stressful Times Beautifying your home is a fun and practical pastime that can o ffer a wonderful sense of accomplishment. Few people may realize, however, that painting the walls, knitting bedspreads or sewing pill ows can help relieve the life pressures we all experience.

Studies indicate that engaging in creative endeavors such as sew ing 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 fa

r 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 th ey can be enjoyed every day. In stressful times, the photos can lift your spirits as you recall hap

py moments.

3. If your schedule is hectic, choose a practical project that will make the most of crafting time. I

f a simple kitchen curtain needs to be replaced, start there.

Change sometimes compels us to see things in new ways.

it, 未知,push ,take her education, seriously

原文She Doesn't Seem Ready for College

Hi, Jenny, you don't look happy. 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 choic

e 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 datin g, 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 coll ege off 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 colle ge 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.

Exercise 1: 1. D 2. C

Exercise 2:

Leaves are Nature's food factories. Plants take water from the ground through their roots and c arbon 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 beca use 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 re ds 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.

答案Where,

原文For years Mr. Urquhart and his colleagues wondered where the migratory monarchs spent th e winter. (第3、4空答案mystery仅供参考，his colleagues wondered)Despite their hopes, fieldwor k 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 volunteer s to report sightings of the butterfly and help with tagging. Finally, in response came a letter, dat ed February 26, 1973, from a man called Kenneth Brugger in Mexico City, who offered to help fi

nd the butterfly hideaway.

Traveling in his motor home, Brugger drove back and forth across the Mexican countryside, l ooking 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 from Me xico. "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 th at 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 w inter the temperature stays near freezing. It is not cold enough to kill the visiting insects, but it i s chilly enough to keep them from moving about. The butterflies survive on the stored fat from t

heir 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 ne ver been to Mexico. Yet they somehow seek out the same resting places. The mystery of how t hey find their way is left for future scientists to solve.

原文The Girl Who Sounded the Alarm

Kelly worked at a photo shop in San Jose, California. In her 16 months of developing photos she has seen a few strange images. Sometimes there were naked people and sometimes there were photos of dead people from funerals. But what came to her eyes that morning was the sca riest she had ever seen. In the photographs was a young man in black gloves and belt and pan ts, with a white T-shirt saying Natural Selection. He was seen either vigorously waving pipe bom bs in the air or holding a shotgun. In the background of the photographs Kelly could see pipe b ombs with nails taped all around them so they would hurt people when the bombs went off.

Photo clerks at her shop are told to report possible suspects of various crimes to authorities. Sometimes, however, there is no clear direction on what should be reported. But the photos of t

he young man left no doubt in Kelly's mind.

Kelly turned to her boss and said, "I'm going to call the police." But the manager hesitated, f or he was afraid that this might bring trouble to him and his business. So she consulted her fath er, a veteran police officer, who told her to dial 911 at once.

Officers were waiting when the customer came to pick up the photos. Kelly's decisive action may have prevented mass murder, according to the authorities. The 19-year-old student in the ph otographs had taken the pictures as a final step in a two-year-long plot to blow up and gun dow n crowds of students at his college. He was charged with weapons possession with intent to inju

re and was put in prison.

Brain Organization and Handedness

Scientific studies during the 1970s and early 1980s suggested that differences in left- and righ t-handers' patterns of brain organization may be associated with differences in skills, abilities, and perhaps even personalities. In the large majority of right-handers, about 98 or 99 percent, speec

h is controlled by the left side of the brain.

The right side of the brain, however, is usually used for recognizing and remembering faces and understanding relationships in space. In left-handers, it is difficult to know exactly their patter ns of brain organization. About 65 to 70 percent of left-handers have speech controlled by the le ft side of the brain, which is also true of right-handers. But in 30 to 35 percent of left-handers s peech is controlled by the right side of the brain. In some left-handers, both sides of the brain a

re capable of controlling speech.

PART D

Preparing for a Negotiation

I think first of all one needs to be prepared. I mean to know what you want from a negotiatio n, what your aims and objectives are. Without clear aims, you can't have clear thinking, so aims are vital. What do you want? A contract? A firm agreement? Or just to find out a few things?

Then, you have to know what's the minimum deal. Decide what is the lowest offer you can a

ccept for a deal.

Then you have to know where you can give way, or make concessions. So fixing concession s and targets is important. Without that you end up agreeing to something and later you think " Oh no, that's a bad deal!" Or you miss out on what seemed a bad deal at the time but was in

fact okay, not bad anyway.

Another area is to know your strengths and your weaknesses. This is as important as being aware of the opportunities and threats -- or dangers -- that exist outside, from competitors for ex ample. So, know the market, know your strengths, and know about prices and other possibilities. If you do this, you can see the negotiation in its proper context. Then you need to prepare all supporting information. Figures, numbers, pictures, whatever. It could be anything, but the most i mportant thing is that you can support what you say. It helps you to be clear.

eds a clear role, clear responsibilities.

Finally, your opening remarks. Prepare what to say. Begin in general terms what you hope to achieve -- the general intention, what you're looking for. (答案hopes to achieve)The opening stat ement sets up the right atmosphere, the right expectations, it helps things to be clear between th

e two sides.

The Blonde and the Lawyer

A blonde and a lawyer were seated next to each other on a flight from Los Angeles to New York. The lawyer asked her if she would like to play a fun game with him.(3答案He asked her

a question ,she did so)（4答案No）

The blonde, tired, just wanted to take a nap. She politely declined and rolled over to the win dow to catch a few winks. The lawyer persisted and explained that the game was easy and a lo t of fun. He explained, "I'll ask you a question, and if you don't know the answer, you pay me $5, and vice versa." Again, she declined and tried to get some sleep. The lawyer, now anxious and nervous, said, "OK, if you don't know the answer you pay me $5, and if I don't know the a nswer, I'll pay you $500."(5答案he paid her $500,she paid $5) This caught the blonde's attention and as she figured there would be no end to this torment

unless she played, she agreed to the game.

The lawyer asked the first question. "What's the distance from the earth to the moon?" Witho ut saying a word, the blonde reached into her purse, pulled out a $5 bill and handed it to the la

"OK," said the lawyer, "your turn." She asked the lawyer, "What goes up a hill with three leg

s and comes down with four legs?"

The lawyer, puzzled, took out his laptop computer and searched all his references, no answer. He searched the Internet and the Library of Congress, still no answer. Frustrated, he sent e-mai ls to all his friends and co-workers, to no avail. After an hour, he woke up the blonde, and hand ed her $500. "Thank you," the blonde said and turned back to get some more sleep.

The lawyer, who was a bit angry, woke her up again and asked, "Well, what's the answer?"

Without a word, the blonde reached into her purse, handed the lawyer $5, and went back to sleep. (7答案The blonde won 490.The lawyer lose 490.)(8答案clever,stupid, the opposite)

From Rags to Riches

In the 1990s, Demi Moore was a major movie star and, as the wife of Bruce Wilis, one half of a Hollywood power couple. Life was good. She had a multimillion-dollar mansion in Los Angel es, a 25-acre ranch in Hailey, Idaho. Nothing about that glamorous life had anything in common

with her poor childhood.

She grew up in New Mexico. Her parents were hard drinkers who moved her and her half-br other 30 times before settling in Los Angeles when she was 14. Fiercely ambitious, Moore began modeling while at high school and dropped out at 16 to pursue an acting career. Soon after sh e turned 18, she got a part in a popular soap opera. But her big break came in 1985 when she

starred as a drug addict in a hit movie.

Moore met Bruce Wilis in 1987. It was love at first sight. They got married in Las Vegas four months later. The next year, Wilis starred in Die Hard, making him one of Hollywood's top-paid actors, while Moore's success in Ghost and A Few Good Men boosted her paycheck to more th

an $12 million per movie.(In the 1990s答案未知)

These were followed by three big-budget movies, one of which was The Scarlet Letter. Then her career stalled. And in October 2000, her 13-year-old marriage ended in divorce. Later she m oved out of Hollywood. Since then, she has been living a simpler life, residing full time in her ra nch in Idaho. Her ambition is now focused not on stardom but on being a good mother to her d aughters with Wilis. "My goal is to build a loving relationship so that my children, as adults, will

want to share their lives with me," she said.

原文The French Franc

For a century much attached to national symbols, France took the imminent death of the franc calmly. It was as if an ancient great-great uncle were about to pass away: a time for nostalgia

and regret, rather than grief.

Unlike the German mark, the franc had never been a symbol of national rebirth or glory. Its r ecent history was relatively stable but it had to be revalued as recently as 1960. In the 1950s, it s value and reputation were so weak that French politicians considered abolishing it and replacin

g it with something else, based on the value of the pound.

But money is money after all. It is with us every day. It was surprising that such a conservati ve people did not express greater sorrow for the loss of their familiar francs. It was also surprisi ng they did not feel a greater sense of aesthetic loss for the franc had always been one of the

The name franc was first used in 1360, to celebrate and help to pay for the release of King Jean II, who was captured by the still poundless English. He created the "franc" or "free" to cele brate the occasion. Over the next 400 years the name came and went but was finally restored b y the Revolution in 1795. On February 17th, 2002, the French franc disappeared completely from

the financial scene.

Exercise 2:

In the 20th century there were two main theories on the origin of the universe. One is the stea dy state theory, and the other, the big bang theory. According to the former, the universe has al ways existed and will exist forever. If this view were correct, the universe should have looked th e same millions of years ago as it looks now. but astronomers have found that the old universe did not look the same as it does now. therefore, the steady state theory does not seem to be c

orrect.

The big bang theory states that the universe began in a massive explosion at a single point in space about 15 million years ago. If the statement were right, there should exist in the universe the cosmic background radiation from the explosion. Researchers have found evidence for its ex istence. In the 1960s, while studying radio signals from the Milky Way. researchers at Bell Labs found their work experiencing interference from every direction. They discovered that the interfere

nce turned out to be the cosmic background radiation . So the big bang theory appears to be th

e correct.

原文Hubble's Closest Look at Mars

NASA is releasing several images taken by the Hubble Space Telescope, which is the closest yet look at the red planet. Altogether there are four images, which show the entire planet. Each view shows the planet as it completes one quarter of its daily rotation. In these views the north polar cap is turned toward the Earth and is clearly visible at the top of each picture. The image s were taken in the middle of the Martian northern summer, when the polar cap was at its small est size. During this season the sun shines continuously on the polar cap. Previous spacecraft o bservations have shown that this summertime polar cap is composed of water ice, just like Earth'

s polar caps.

The Hubble Telescope pictures reveal that great changes have occurred on the surface of Ma rs in the past 20 years. The Martian surface is ever changing. Some regions that were dark 20 years ago are now bright red; some areas that were bright red are now dark. Winds move sand and dust from region to region, often in huge dust storms. Over long timescales many of the la rger bright and dark markings remain stable, but smaller details come and go as they are covere

d and then uncovered by sand and dust.

The Hubble pictures reveal that the surface of Mars is covered with a lot of volcanic rocks. B ut mysteries still remain. Has there been life on Mars? Is there life on it now? How different is it from our own planet? These are a few of the questions waiting to be solved.
