Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman Empire. But when the empire broke down, this kind of tourism stopped.
In the early 17th century, the idea of the “Grand Tour” was born. Rich young English people sailed across the English Channel. They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice（威尼斯）in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The “Grand Tour” was an important part of young people’s education-but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to “take the waters”. They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.
Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to faraway countries.
The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
Thus tourism grew, in 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything-plane tickets, hotel rooms, even food-and tourists pay for it all before they leave home. The package tour and modern tourist industry was born and began to take off.

There is a lot of misunderstanding about studying. Most students have not been taught the principles behind really effective working. Imagine a graph showing the amount a person learns against the number of hours he works in a day. If he doesn’t do any work, he learns nothing (point 0). If he does an hour’s work he learns a certain amount (point 1). If he does two hours’ work he learns about twice as much (point 2). If he does more work he’ll learn still more (point 3). However, if he tries to do twenty-three and a half hours’ work in a day, he will be so tired that he’ll hardly remember anything: what he learns will be very little (point 4). If he did less work he’d learn more (point 5).
Now whatever the exact shape of the graph’s curve(曲线), made by joining these points, it must have a high point. Point “X” is the very maximum anyone can learn in the day. And this represents the optimum(最适度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(劳累). Fatigue is an absolutely real thing; one can’t escape it or ignore it. If you try to ignore it and press yourself to work past the optimum, you will only get on this downward slope and achieve less than the best – and then become very tired and lose your power of concentration.
The skill in being a student consists of getting one’s daily study as near the optimum point as possible. I cannot tell you what the optimum is. It differs with the type of work, it differs from person to person, and even in the same person it varies from week to week. You must try to find your own. Every day you study, bear this principle of the optimum in mind. When you feel yourself getting fatigued, if you find yourself reading the same paragraph over and over again and not taking it in, that’s a pretty good sign you’ve reached your highest point for the day and should stop. Most ordinary students find their optimum at five hours a day. Yours may be a little more or a little less – but if you get in five hours’ good work a day, you will be doing well.
Now, what are you doing with yourself when you aren’t working? Before examinations some students do nothing at all except sit in a chair and worry. Here is another misunderstanding. People often think that the mind works like the body; it does not. If one wanted to save one’s physical energy in order to cut the maximum amount of firewood, one would lie flat on a bed and rest when one wasn’t chopping. But the mind cannot rest. Even in sleep you dream, even if you forget your dreams. The mind is always turning. It gets its relaxation only by variety. That is what makes the mind rest.
When you’ve finished your optimum number of hours you must stop. You must not then sit around in the chair thinking about the work – that only tires without any learning. You must get out and do something. It doesn’t matter what – anything so long as you are actively doing something else but work

Fans of the British royal family around the world are making plans for April 29th, 2011. That’s the date that Prince William and Catherine Middleton are to tie the knot at Westminster Abbey in London.
A royal wedding is a rare and unique event in Britain so for many it’s something worth celebrating, particularly if you are in the business of making memorabilia (收藏品).
Producers of these souvenirs are wasting no time in manufacturing key rings, mugs, teapots and tea towels, mostly with the faces of the happy couple emblazoned on the front. These are the must buy items that royal followers want to get their hands on.
Some people may argue the royal wedding is a huge public cost but production and sale of memorabilia is good for business. Former politician, Lord Archer, has commented that, “In this age when we are trying to balance the books, the royal family are a great benefit to Great Britain Limited.”
A porcelain-making company, called Royal Crown Derby, is already manufacturing souvenir pottery. Louise Adams from the company says “we started designing, truly, about two years ago.” It is big business for China too, where much of the merchandise that marks the big event is made.
But why are people so keen to get their hands on a commemorative mug, so much so that one British supermarket has already seen them flying off the shelves?
Obviously, we like to remember an event like this and maybe it makes us feel as though we are part of the occasion. However their monetary value is likely to be low. Eric Knowles from the BBC’s Antiques Roadshow claims, “The vast majority of it will be worthless.”
Modern day souvenirs tend to be mass-produced making them cheap and easy to find. However limited edition or high-end items tend to keep their value and could be a better investment for the future.
But there is one thing we can guarantee that won’t be mass-produced and cheap. That’s the wedding dress for Princess Catherine, as Catherine Middleton will be known

Home to me means a sense of familiarity and nostalgia(怀旧). It's fun to come home. It looks the same. It smells the same. You'll realize what's changed is you. Home is where we can remember pain, live, and some other experiences; We parted here; My parents met here; I won three championships here.
If I close my eyes, I can still have a clear picture in mind of my first home. I walk in the door and see a brown sofa surrounding a low glass-top wooden table. To the right of the living room is my first bedroom. It's empty, but it's where my earliest memories are.
There is the dining room table where I celebrated birthdays, and where I cried on Halloween-when I didn't want to wear the skirt my mother made for me. I always liked standing on that table because it made me feel tall and strong. If I sit at this table, I can see my favorite room in the house, my parents' room. It is simple: a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side. Their bed is my safe zone. I can jump on it anytime - waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning.
I'm lucky because I know my first home still exists. It exists in my mind and heart, on a physical property (住宅) on West 64th street on the western edge of Los Angeles. It is proof I lived, I grew and I learned.
Sometimes when I feel lost, I lie down and shut my eyes, and I go home. I know it's where I'll find my family, my dogs, and my belongings. I purposely leave the window open at night because I know I'll be blamed by Mom. But I don't mind, because I want to hear her say my name, which reminds me I'm home

In the 18th century, New York was smaller than Philadelphia and Boston. Today it is the largest city in America. How can the change in its size and importance be explained?
To answer this question we must consider certain facts about geography, history, and economics. Together these three will explain the huge growth of America’s most famous city.
The map of the Northeast shows that the four areas with the largest populations in this region are around seaports. At these points materials from across the sea enter the United States, and the products of the land are sent there for export across the sea.
We know that places where transportation lines meet are good places for making raw materials into finished goods. That is why seaports often have cities nearby. But cities like New York needed more than their geographical location in order to become great industrial centers. Their development did not happen simply by chance.www.zxxk.com
About 1815, when many Americans from the east had already moved toward the west, transportation routes from the seaports to the central regions of the country began to be a serious problem. The slow wagons of that time, usually drawn by horses, were too expensive for moving heavy freight (货物) very far. In New York State a canal seemed the best answer to the transportation problem. From the eastern end of Lake Erie all the way across the state to the Hudson River there is a long strip of low land. Here the Erie Canal was built, and after several years of work it was completed in 1825.
The canal produced an immediate effect. Freight costs were cut to about one tenth of what they had been. New York City, which had been smaller than Philadelphia and Boston, quickly became the leading city of the coast. In the years that followed, transportation routes on the Great Lakes were joined to routes on the Mississippi River. Then New York City became the end point of a great inland shipping system that started from the Atlantic Ocean far up the western branches of the Mississippi

Everyone has got two personalities — the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behaviour, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to upset people, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You’re very stubborn, but you aren’t very ambitious. You usually live for today not for tomorrow. This means that you enjoy having a good time.
If you sleep on curled up, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weakness. You’re usually careful. You have a confident personality. You sometimes feel anxious, but you don’t often get depressed. You always say what you think even if it annoys people

Elizabeth Blackwell was born on February 3, 1821 in Bristol, England. Her father was a rich sugar businessman at the time. Because her parents thought boys and girls should be equal, Elizabeth received the same education as her brothers.
In 1832, her father’s business was destroyed by fire, so her family moved to New York City. But her father’s business there failed. Then in 1837, the family moved to Cincinnati, Ohio. Not long after, her father died. After her father’s death, Elizabeth, at the age of 16, had to go to work.
When she was 24, she visited her dying friend Mary. Her friend said, “You’re young and strong, you should become a doctor.” That was nearly impossible for a woman in the middle of the nineteenth century. But she knew this was what she was going to do.
After several rejections from medical schools, she finally was accepted by Geneva Medical College. By studying hard, she graduated successfully in 1849.
After graduating from medical school, she went to Paris to learn more about medicine. She wanted to be a surgeon, but a serious eye problem forced her to give up the idea.
When she returned to America in 1851, she found it difficult to start her own practice because she was a woman. In 1857, Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides, she also set up the first medical school for women in 1868, where she taught the women students about disease prevention. It was the first time that the idea of preventing disease was taught in a medical school.
Elizabeth Blackwell started the British National Health Society in 1871, which helped people learn how to stay healthy. In 1889, Elizabeth Blackwell became the first woman doctor in the United States. Most importantly, she fought for the admission of women to medical colleges.
Elizabeth Blackwell died on May 3, 1910, when she was 89.She opened a world of chances for women. She always fought for what was right in all her life. In 1949 the Blackwell medal was established. It’s given to women who have excellent achievements in the field of medicine. She’ll always be remembered as a great woman

An “apple polisher” is one who gives gifts to win friendship or special treatment. It is not exactly a bribe(贿赂), but is close to it.
All sorts of people are apple polishers, including politicians and people in high offices—just about everybody. Oliver Cromwell, the great English leader, offered many gifts to win the support of George Fox and his party, but failed.
There are other phrases meaning the same thing as “apple-polishing”—“soft-soaping” or “buttering-up”. A gift is just one way to “soft-soap” somebody, or to “butter him up”. Another that is just as effective is flattery, giving someone high praise—telling him how good he looks, or how well he speaks, or how talented and wise he is.
Endless are the ways of flattery. Who does not love to hear it? Only an unusual man can resist the thrill of being told how wonderful he is. In truth, flattery is good medicine for most of us, who get so little of it.
We need it to be more sure of ourselves. It cannot hurt unless we get carried away by it. But if we just lap it up for its food value and nourishment, as a cat laps up milk, then we can still remain true to ourselves.
Sometimes, however, flattery will get you nothing from one who has had too much of it. A good example is the famous 12th century legend of King Canute of Denmark and England. The king got tired of listening to endless sickening flattery of his courtiers(朝臣). They overpraised him to the skies, as a man of limitless might.
He decided to teach them a lesson. He took them to the seashore and sat down. Then he ordered the waves to stop coming in. The tide was too busy to listen to him. The king was satisfied. This might show his followers how weak his power was and how empty their flattery

Even if we have an extremely healthy diet and lifestyle, the human body is programmed to wear out at a maximum of about 120 years, and usually less. We all have a biological clock inside us which determines the moment when our organs cease to function properly. This is because our cells have stopped renewing themselves and our body can no longer repair itself. This is also the moment when we are more likely to begin to suffer from the diseases of old age such as arthritis and Alzheimer’s. However, rapid advances in DNA research are beginning to throw light on the secrets of the ageing process. By the end of this century we could literally have the power of life over death.
Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to live indefinitely. The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing.
Another new area of research involves the oxidation（氧化） theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young.
Perhaps the most immediate advance we are likely to see in the battle to halt（停止）the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing injured bones or even organs like livers and kidneys with ones “grown” in laboratories. By 2050 perhaps every organ in the body, except the brain, will have become commercially available. Recent experiments also show that it may one day be possible to “grow” new organs inside our body to replace worn-out ones, something which lizards and alligators already do.
Suddenly immortality（不死，不朽） seems within reach. We can begin to imagine a future where we are born, we grow to maturity, but we never grow old and die. But do we really want to live forever?
