How did people ever live without zippers?They are very common, so we forget that they are wonderful. They are very strong,but they open and close very easily. They come in many colors and sizes.In the 1890s, people in the United States wore high shoes with a long row of buttons. Clothes often had rows of buttons, too. People wished that clothes were easier to put on and take off.Whitcomb L. Judson, an engineer from the United States, invented the zipper in 1893. However, his zippers didn't stay closed very well. This was embarrassing, and people didn't buy many of them. Then Dr. Gideon Sundback from Sweden solved this problem. His zipper stayed closed.A zipper has three parts: 1.Thereare dozens of metal or plastic hooks (called teeth) in two rows. 2. These hooks are fastened to two strips of cloth. The cloth strips are flexible. They bend easily. 3. A fastener slides along and joins the hooks together.When it slides the other way, it takes the hooks apart.Dr. Sundback put the hooks on strips of cloth. The cloth holds all the hooks in place. They don't come apart very easily. This solved the problem of the first zippers.(212 words)2 The Postage StampBefore the invention of the postage stamp, it was difficult to send a letter to another country. The sender paid for the letter to travel in his or her own country.Then the person in the other country paid for the rest of the trip. If a letter crossed several countries, the problem was worse.Rowland Hill, a British teacher, had the idea of a postage stamp with glue on the back. The British post office made the first stamps in 1840. They were the Penny Black and the Twopence Blue. A person bought a stamp and put it on a letter. The post office delivered the letter. When people received letters, they didn't have to pay anything. The postage was prepaid.Postage stamps became popular in Great Britain immediately. Other countries started making their own postage stamps very quickly.There were still problems with international mail. Some countries did not want to accept letters with stamps from other countries. Finally, in 1874, a German organized the Universal Postal Union (UPU). Each country in the UPU agreed to accept letters with prepaid postage from the other members. Today, the offices of the UPU are in Switzerland. Almost every country in the world is a member of this organization. It takes care of any international mail problems.Today, post offices in every country sell beautiful stamps. Collecting stamps is one of the most popular hobbies in the world, and every stamp collector knows about the Penny Black and the Twopence Blue.(250 words)3 Pencils and PensNo one knows who invented pencils or when it happened. A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead inside it. (Lead is a very heavy, soft, dark gray metal.) Pencils weren't popular, and people continued to write with pens. They used bird feathers as pens.Then, in 1795, someone started making pencils from graphite, and they became very popular. Graphite is like coal. (Coal is black, and we burn it for heat and energy.) Today, people make pencils in the same way. They grind the graphite, make it into the shape of a stick, and bake it. Then they put it inside a piece of wood. One pencil can write 50,000 English words or make a line 55 kilometers long.People wrote with feather pens and then used pens with metal points. They had to dip the point into ink after every few letters. Next, someone invented a fountain pen that could hold ink inside it. A fountain pen can write several pages before you have to fill it again.Two Hungarian brothers, Ladislao and Georg Biro, invented the ballpoint pen.They left Hungary and started making ballpoint pens in England in 1943, during World War II. English pilots liked the pens. They couldn't write with fountain pens in airplanes because the ink leaked out. Later, a French company called Bic bought the Biros' company.Some people call ballpoint pens "Bics." Australians call them "biros." Whatever we call them, we use them every day.(256 words)4 The UmbrellaThe umbrella is a very ordinary object. It keeps the rain and the sun off people.Most umbrellas fold up, so it is easy to carry them.However, the umbrella has not always been an ordinary object. In the past, it was a sign of royalty or importance. Some African tribes still use umbrellas in this way.Someone carries an umbrella and walks behind the king or important person.Umbrellas are very old. The Chinese had them more than 3,000 years ago. From there, umbrellas traveled to India, Persia, and Egypt. In Greece and Rome, men wouldn't use them. They believed umbrellas were only for women.When the Spanish explorers went to Mexico, they saw the Aztec kings using umbrellas. English explorers saw Native American princes carrying umbrellas on the east coast of North America. It seems that people in different parts of the world invented umbrellas at different times.England was probably the first country in Europe where ordinary people used umbrellas against the rain. England has a rainy climate, and umbrellas are very useful there.Everybody uses umbrellas today. The next time you carry one, remember that for centuries only great men and women used them. Perhaps you are really a king or queen, a princess or prince.(210 words)5 The Metric SystemPeople all over the world use grams, kilograms (kilos), meters, and liters. These are all ways to measure things. They are all part of the metric system.During the French Revolution (1789-1799) against the king, the revolutionary government started the metric system. Before that, every part of France had a different system for measuring things. Also, cloth makers measured cloth with one system. Jewelers used another system. Carpenters used another. Other countries used different systems. The revolutionary government wanted one scientific system of measurement. They asked a group of scientists and mathematicians to invent a system.The mathematicians and scientists decided to use the numbers ten, hundred, and thousand for their system.Next, they had to decide on a "natural" length. They chose one ten-millionth (1/ 10,000,000) of the distance from the equator to the North Pole. They called this distance the meter. Then they chose the gram for weighing things. A cubic centimeter of water weighs 1 gram.Mathematicians and scientists worked for 20 years until they finally had a complete measuring system. The biggest problem was measuring the meter.The metric system was a wonderful gift to the world. There are only a few countries that don't use it. The United States is one. The metric system is truly an international system.(214 words)6 Thai BoxingBoxing is popular in many countries. Two fighters wear boxing gloves on their hands. The boxers hit each other until one is knocked out or until the final bell rings.Each part of the fight is three minutes long. It is called a round.Thai boxing is different.The boxing match begins with music. Then the two fighters kneel and pray to God. Next, they do a slow dance that copies the movements of Thai boxing. During this dance, each fighter tries to show the other that he is best.Then the fight begins. In Thai boxing, the fighters can kick with their feet and hit each other with their elbows and knees. Of course, they hit with their hands, too.Each round is three minutes long. Then the boxers have a two-minute rest. Most boxers can fight only five rounds because this kind of fighting is very difficult.Thai boxing began over 500 years ago. If a soldier lost his weapons in a battle, he needed to fight with just his body. The soldiers learned how to use all the parts of their bodies. In 1560, the Burmese army captured Naresuen, the King of Thailand, in a war. King Naresuen was a very good boxer. He won his freedom from Burma by defeating all the best Burmese fighters. When he returned to Thailand, his people were very proud of him. Thai boxing became a popular sport.(237 words)7 Sumo WrestlingSumo wrestling is a national sport in Japan. Every year there are six tournaments,and millions of Japanese watch them on television. A tournament is a series of matches.Sumo is almost as old as the nation of Japan itself. Stories say that there was sumo wrestling over 2,000 years ago. There are written records of national sumo tournaments in the 8th century.In many sports, athletes are thin and can move very quickly. However, sumo wrestlers weigh from 100 to 160 kilos (kilograms). One famous wrestler weighed 195kilos. Sumo wrestlers do not move quickly, and sumo wrestling is a very slow sport.Sumo wrestlers start training when they are boys. They exercise to make their bodies strong. They also eat a lot.They wrestle in a round ring with a sand floor. A wrestler loses the match if he leaves the ring. He is also the loser if any part of his body except his feet touches the floor. Each wrestler tries to push the other down on the floor or out of the ring.Sometimes one wrestler just steps aside when the other wrestler rushes toward him.Then, the wrestler who is rushing falls down or moves out of the ring.Sumo is not very popular in other countries, but the Japanese think that it is a very exciting sport.(223 words)8Tarahumara Foot RacesThe Tarahumara live in the mountains in the state of Chihuahua in northern Mexico. This is an area of high mountains and deep tropical valleys. It sometimes snows in the mountains in winter. There are not many roads.The Tarahumara walk wherever they need to go. They carry heavy baskets on their backs. Perhaps this is why the Tarahumara can run many kilometers without getting tired. They are excellent runners, and they like to organize races.When the men race,they kick a wooden ball ahead of them while they run. Before they start racing, they plan where and how long they will run. They might run just a few minutes, or they might run for several hours. Sometimes they run in teams, and sometimes each person runs as an individual.The women's races are similar except that the women do not kick a ball. They throw a wooden hoop in front of them with a stick. A hoop is a ring, or a circle.The Tarahumara play other games and sports. However, they are famous because they can run so fast and so far.(185 words)9 Olympic SportsThe first modern Olympic Games took place in Athens, Greece, in the year 1896.Athletes from only 13 countries participated in the Games that year. They competed in 43 different events in just 9 sports (track and field, swimming, cycling, fencing,gymnastics, shooting, tennis, weight lifting, and wrestling). In 2004, the summer Olympic Games took place once again in Athens, Greece. This time athletes from 202 countries competed in 300 events in 28 sports.Only five sports have been in every Olympic Games. They are track and field,swimming, fencing, cycling, and gymnastics. Other sports come and go in the Olympic Games. For example, tennis was an Olympic sport from 1896 until 1924.Then it disappeared from the Olympics until 1988. Baseball, badminton, and taekwondo are more recent additions to the Olympic Games.It is the job of the International Olympic Committee (IOC) to add and remove sports from the Olympic Games. A sport has to be popular in at least 50 countries on three continents before it can be added. However, the IOC doesn't want to add more sports to the Olympic Games without eliminating others. The IOC is afraid that there will be too many sports in the Olympics.Artistic events were also a part of the Olympic Games from 1912 to 1948. There were contests in architecture, music, literature, and painting. Today some people think that artistic events and games such as chess should be part of the Olympics.However, many people oppose this idea.The Olympic Games today are very different from the first modern Olympic Games in 1896. These differences reflect the changing definition and popularity of sports.(273 words)10 Great AthletesYou might think that Olympic athletes are the healthiest people in the world. It's true that many are. However, it's also true that quite a few Olympic athletes had to overcome illnesses early in their lives.One excellent example is Wilma Rudolph. She competed in track-and-field events in the 1960 Olympics. She didn't win just one gold medal. She won three. At the time, people called her "the fastest woman in the world."As a young child, Wilma Rudolph could not participate in sports. She had a series of serious illnesses, and then, at the age of 4, she got polio. She lost the use of her left leg, and the doctors said she would never walk again.The people in Rudolph's family did everything they could to help her walk again.Wilma and her mother frequently traveled 100 miles to get treatments for her leg. Her brothers and sisters took turns giving her leg a daily massage. Four times a day, they helped her do special exercises for her leg. Amazingly, by the time Rudolph was 9years old, she was able to walk again. Before long, she started playing basketball and running. In high school, she was a track star, and then she went to the Olympics.Wilma Rudolph retired from her career as a runner when she was 22 years old.She then became a teacher and track coach. Her story encouraged many people to work hard and to overcome difficulties.(244 words)11The Puffer FishMost people avoid eating dangerous foods. They don't want to get sick. However,there is one food that can be deadly, yet some people eat it on purpose. It's called the puffer fish.This kind of fish, called fugu in Japanese, lives in the Pacific Ocean. Some people die every year from eating fugu. In fact, the Emperor of Japan is not allowed to touch it. Why? Well, the insides of the puffer fish are very poisonous. They contain a poison 275 times more powerful than the deadly poison cyanide.Usually nothing bad happens when fugu is on a restaurant's menu. Customers feel great after the meal. That's because chefs are trained to remove the insides of the puffer fish before they give it to customers. If they miss even a small amount, the fish is not safe to eat.Puffer fish is very expensive. A plate of fugu costs more than $200 in some restaurants in Tokyo. Besides being dangerous to eat, the fish is very ugly, with spines all over its body. Also, it can puff, or blow, itself up to double its normal size.Why do the Japanese risk so much for such an ugly and dangerous fish? Well, some people like taking risks. And fugu tastes wonderful.(211 words)12 Foods from Around the WorldFoods that are well known to you may not be familiar to people from other countries. Tourists and other travelers almost always get to try some unfamiliar food.That is part of the fun of traveling. Here are four people's experiences with foreign food.Shao Wong is a student in France. He comes from China. "I never had cheese or even milk before I came to France. Cattle are rare in my part of China, so there are no dairy products. I drank some milk when I first arrived in France. I hated it ! I tried cheese, too, but I didn't like it. I love ice cream, though, and that's made from milk."Birgit is from Sweden. She traveled to Australia on vacation. "I was in a restaurant that specialized in fish, and I heard some other customers order flake. So I ordered some, too, and it was delicious. Later, I found out that flake is an Australian term for shark. Now, whenever I see a new food, I try it on purpose. You know why? I remember how much I enjoyed flake."Chandra is a dentist in Texas. She is from India. "I'm afraid to try new foods because they might contain beef. I'm a Hindu, and my religion forbids me to eat meat from the cow. That's why I can't eat hamburgers or spaghetti with meatballs."Nathan is from the United States. He taught for a year in China. "My friends gave me some 100-year-old eggs to eat. I didn't like their appearance at all. The eggs were green inside, but my friends said the color was normal. The Chinese put chemicals on fresh eggs. Then they bury them in the earth for three months. So the eggs weren't really very old. Even so, I didn't want to touch them."Life in a new country can be scary, but it also can be fun. Would you eat a 100-year-old egg? Would you order shark in a restaurant?(328 words)13 ChocolateWe think of chocolate as something sweet. However, a long time ago, people thought of chocolate as something very bitter. For us, chocolate is a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack.Sometimes it's an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.Chocolate is a product of the tropical cacao tree. Cacao beans taste so bitter that even monkeys say "ugh!" and run away. The word chocolate comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some of the Mayas used cacao beans for money, while others ground them to make a bitter drink.When the Spaniards came to Mexico in the 16th century, they started drinking cacao, too. Because the drink was strong and bitter, they thought it was a medicine.When the Spaniards took the drink back to Europe, people discovered that sugar removed the bitter taste of cacao. Wealthy Spaniards heated the sweet drink and thought that it was good for their health.In the 19th century, an English company made the first solid block of sweetened chocolate. Now people could both drink and eat chocolate. Later, a Swiss company mixed milk and chocolate together. People liked the taste of milk chocolate even better.Besides the chocolate candy bar, one of the most popular American snacks is the chocolate-chip cookie. Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.(280 words)14 The Blue RevolutionThe population of the world is increasing rapidly. By 2020, there could be 7.5billion people on earth. Will there be enough food for all these people, or will we have a food shortage? Some scientists think fish farming could solve this problem.However, other scientists worry that fish farming could cause serious environmental problems.Fish farming is not a new thing. There were fish farms in China 3,000 years ago.Today, about one-third of the fish we eat comes from fish farms.Most fish farms raise plant-eating fish. Popular kinds of plant-eating fish are carp,tilapia, and catfish. Unfortunately, many fish farms are starting to raise meat-eating fish. A popular type of meat-eating fish is salmon. These meat-eating fish live on processed food made from wild fish. However, it takes up to 5 tons of wild fish to produce just 1 ton of farm-raised salmon. The supply of wild fish is already decreasing. Eventually, many types of wild fish could become extinct. What will we do then?Critics of fish farming also say that farm-raised fish is unhealthy for humans.They say the fish contains dangerous chemicals. They also criticize fish farming because it pollutes the water. Another criticism is that farm-raised fish can spread diseases to wild fish.Some people say that the farming methods being used now won't produce enough fish anyway. Instead of putting fish farms in lakes or near the coast, they say that the fish farms should be moved far out into the ocean. Several countries are already experimenting with deep-ocean farms. In the future, fish farms might be large cages that move across the ocean.Like most things, there is both a good and a bad side to fish farming. Fish farming may help to feed millions of people.At the same time, however, fish farming may damage the environment.(307 words)15 Twenty-One Days Without FoodWhy would someone decide to stop eating? We know that the body needs food in order to function well. However, many people fast at some time during their lives.Why is this?Some people fast for political reasons. In the early 20th century, women in England and the United States weren't allowed to vote. In protest, many women went on fasts. They hoped that fasting would bring attention to this injustice. Mohandas Gandhi, the famous Indian leader, fasted 17 times during his life. For Gandhi, fasting was a powerful political tool. In 1943, he fasted to bring attention to his country's need for independence. For 21 days, he went without food. Another famous faster was Cesar Chavez. In the 1960s, he fasted for three weeks. Why? His goal was to bring attention to the terrible working conditions of farm workers in the United States.Fasting is also a spiritual practice in many religions. Every year during the month of Ramadan, which is a religious holiday, Muslims fast from sunrise to sunset. Many Hindus fast on special occasions, as do some Christians and Buddhists.Of course, not everyone fasts for political or religious reasons. Some people occasionally fast just because it makes them feel better. The American writer Mark Twain thought fasting was the best medicine for common illnesses. Whenever he had a cold or a fever, he stopped eating completely. He said that this always made his cold or fever go away. Another American writer, Upton Sinclair, discovered fasting after years of overeating, indigestion, and headaches. His first fast lasted for 12 days.During this time, his headaches and stomachaches went away.Sinclair said that fasting also made him more alert and energetic.Choosing to go without food can be very dangerous. However, that doesn't stop people from fasting for political, religious, or health reasons.(305 words)16 The Marie CelesteThere are many stories about the ocean. One of the strangest is a true story about a sailing ship. It is a mystery even today.In 1872, the Marie Celeste started on a trip across the Atlantic Ocean with a crew of ten people.Sometime later, the captain of another ship, the Dei Gratia, saw the Marie Celeste. There was something strange about its appearance. The captain called out, but there was no answer. The Marie Celeste seemed deserted.When the captain went to inspect the ship, no one came to meet him. He knew something was wrong, but there were no signs of violence. Nothing was missing, and there was no damage to the ship's instruments. And strangely enough, there was food on the table. Where was everyone? Did the crew jump from the Marie Celeste? Or did something come up from the ocean and take the captain and crew away?The captain of the Dei Gratia looked around for clues. The last entry in the Marie Celeste's diary was ten days earlier. However, the food on the table was only a few days old. Someone was on the ship a few days before, but they didn't write anything in the ship's diary. Why?There were many different explanations for the mystery of the Marie Celeste.Some people thought that a huge octopus ate the crew. Others said bad weather carried them away. A few people believed that the Marie Celeste was under a curse,because it sank on a later voyage. Now that the Marie Celeste lies somewhere at the bottom of the ocean, no one can ever solve the mystery.(274 words)17 The Roanoke SettlementOnly a few Europeans lived in North America in the 16th century. Most of them settled on the northeast coast. In 1587, a small group of about 100 people decided to 11/20go south. They moved to the small island of Roanoke. That area later became part of the state of North Carolina.Unfortunately, the Roanoke settlers weren't well prepared. They didn't have enough food for the winter, and there wasn't enough grain for future crops. Their leader, Captain White, decided to sail back to England to get supplies. However,there was a war in Europe, and three years passed before he returned to North America.When Captain White came back to Roanoke in 1590, he was eager to see the settlers. He looked out from his ship, but no one was there to meet him. There were no signs of life. The settlement was deserted.No one knows why the Roanoke settlers disappeared. Many people thought that hostile Native Americans killed them, but there were no signs of a fight. Some thought that the settlers died from hunger or disease, but they couldn't explain the absence of bodies.Many years later, more settlers came to North Carolina. One of them met a Native American group called the Lumbee. They were unusual looking compared to the black-haired, brown-eyed Native Americans in the north. Some Lumbee had blonde hair and gray eyes. Then he listened to their speech and almost fell off his horse.They seemed to speak an odd kind of English!He asked where they were from. None of them knew, but they said that their grandparents "talked from a book." Did they mean that their grandparents were able to read? As he rode back home,he asked himself a question: Were the Lumbee people the descendants of the Roanoke settlers?People are still asking the identical question. Because there are no written records,we can't be certain. However, there is one interesting fact. Today, some of the Lumbee people have names like Sampson, Dare, and Cooper. They are identical to the names of the vanished settlers ofRoanoke Island.(350 words)18 The Easter Island StatuesWhen the first sailing ship came to Easter Island in 1722 the captain and crew were afraid to land. They saw giants looking down at them from the high cliffs. The giants didn't move, so the ship slowly moved closer. Finally, the sailors realized that the giants were statues. Who made these huge statues? How did they get there?Easter Island is a very small island in the Pacific Ocean. It is more than 2,000miles from the nearest continent (South America). It is one of the most isolated places on earth.The biggest statue on Easter Island is over 60 feet high and weighs over 100 tons.There are hundreds of smaller ones, about 15 feet high. All of the statues are made of stone, and some wear stone hats. Their faces are solemn and unsmiling.Earlier inhabitants of Easter Island made the statues from the rocks in a volcanic crater. Next, they had to move the statues a long distance. In some cases, they moved the statues to locations more than ten miles away.No one knows for certain how the inhabitants were able to move the statues. Some scientists say that palm trees grew on Easter Island in the past. They think the inhabitants cut the trees down and placed the heavy statues on the trees. Then groups of 70 or more people rolled the statues to their present locations. Other scientists disagree with this theory because there are no palm trees on the island today. More important, the purpose of the statues is still a mystery. Was the purpose of the statues to prevent strangers from landing on the island?The result, however, has been the opposite. Large groups of eager people come to look at the statues. Easter Island now has a modern airport, and people come from all over the world to visit.。

It stores food in its hump. The camel’s body changes the food into fat. Then it stores the fat into its hump. It doesn’t store the fat all over its body. Fat all over an animal’s body keeps the animal warm. Camels live in the desert. They do not want to be warm during the day.The desert is very hot. The camel gets hotter and hotterduring the day. It stores the heat in its body because the nights are cool.The Arabian camel has one hump. TheBactrian camel of Central Asia has two humps.It also has long, thick hair because winters are cold in Centre Asia.There is a lot of sand in the desert. The camel has long eyelashes. The eyelashes keep the sand out of the camel’s eyes.Arabic has about 150 words to describe a camel. Many people who speak Arabic need all these words because the camel is very important to them.(185 words)Unit1 Lesson 3（03）The Polar BearThe polar bear is a very big white bear.

U1-Animal : Lesson 4 - The Hippopotamus
The hippopotamus, or hippo, lives in the hot part of Africa. It is a mammal. That is, its babies are born alive, and they drink milk from the mother's body.
The hippopotamus is a large animal. It weighs four tons. Its stomach is seven meters long, and it eats only plants. It is a mammal, but it spends a lot of time in the water.
During the day, it sleeps beside a river or a lake. Sometimes it wakes up. Then it goes under the water to get some plants for food. It can close its nose and stay under water for ten minutes. Its ears, eyes, and nose are high up on its head. It can stay with its body under the water and only its ears, eyes, and nose above the water.Then it can breathe the air.
At night, the hippo walks on the land and looks for food. It never goes very far from the water.
A baby hippo often stands on its mother's back. The mother looks for food underwater. The baby rides on her back above the water. (184 words)
