It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

In 1933 an unknown American called Clarence Nash went to see the film-maker Walter Disney. He had an unusual voice and he wanted to work in Disney’s cartoon film for children. When Walter Disney heard Nash’s voice, he said, “Stop! That’s our duck!”
The duck was the now-famous Donald Duck, who first appeared in 1934 in the film, The Wise Little Hen. Donald lived in an old houseboat and worn his sailor jacket and hat. Later that year he became a star after an eight minute Mickey Mouse film. The cinema audiences liked him because he was lazy and greedy, and because he lost his temper very easily. And they loved his voice when he became angry with Mickey’s eight nephews. Soon Donald was more popular than Mickey Mouse himself, probably because he wasn’t a goody-goody, like Mickey.
In the 1930s, 1940s, and 1950s, Donald and his friends Mickey, Goofy and Pluto made hundreds of Disney cartoons. He also made educational film about the place of the USA in the world, and safety in the home. Then in 1966 Donald Duck and his voice disappeared—there were no more new cartoons.
Clarence Nash died in February, 1985. But today’s children can still see the old cartoons on the television and hear that famous voice.

Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea．People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea．Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added．She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.
At first, tea was usually drunk after dinner in the evening No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o’clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born.

As we all know, it was Thomas Jefferson who wrote the Declaration of the Independence. He wrote it in two weeks, and after a few changes, it was accepted by the Congress. As a result, he became famous.
Born in Virginia, Thomas Jefferson, a brilliant student at school and almost talented lawyer later, was much interested in politics.
Jefferson was elected Governor of Virginia in 1779, and he was sent to France as the representative of the American government in 1784. Sixteen years later, at the age of 57, he was elected president after Washington and Adams.
Far from a handsome man, he was tall with long arms and big hands. Jefferson, who was an amusing talker in conversation but a poor speaker, was generally good-natured.
Jefferson was regarded as a defender of freedom on America. As a president, he protected the right of free speech. Interestingly enough, in his eight years as President, Jefferson never vetoed a bill which Congress had passed. He did a lot in organizing the new University of Virginia.
Thomas Jefferson died on July the fourth, 1826, the 50th anniversary of American Independence.

Research shows that humans switch from selfish to unselfish behavior when they are watched. Do you?
A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a
collection box that has a picture of eyes on it than they do when a flower symbol is on the box.
Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow coded into humans and people respond this way unconsciously, or without realizing it.
It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.

What’s your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to explore the world. So we visit travel agents, compare packages and prices, and pay our money.
We know what our vacation costs us. But do we know what it might cost someone else? It’s true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local people more than it helps them.
It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas（佛塔）in Bagan so that tourists could visit the pagodas.
Tourism might also cost the local people their livelihood and dignity. Local workers often find only menial（卑微的）jobs in the tourist industry. And most of the profits do not help the local economy. Instead, profits return to the tour operators in wealthier countries. When the Maasai people in Tanzania were driven from their lands, some moved to city slums. Others now make a little money selling souvenirs or posing for photos.
Problems like these were observed more than 20 years ago. But now some non-government organizations, tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure.
The result is responsible tourism, or“ethical tourism.”Ethical tourism has people at its heart. New international agreements and codes of conduct can help protect the people’s lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex.
But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn reasonable wages.
They can make it a point to use only locally owned hotels, restaurants and guide services. They can share profits fairly to help the local economy. And they can involve the local people in planning and managing tourism.
What can tourists do? First, we can ask tour companies to provide information about the conditions of local citizens. We can then make our choices and tell them why. And while we’re abroad, we can:
★Buy local foods and products, not imported ones.
★Pay a fair price for goods and services and not bargain for the cheapest price.
★Avoid flaunting(炫耀) wealth.
★Ask before taking photographs of people. They are not just part of the landscape! Let’s enjoy our vacation and make sure others do, too.
