Savannas pose a bit of a problem for ecologists. There is an axiom in ecology that 'complete competitors cannot coexist': in other words, where two populations of organisms use exactly the same resources, one would be expected to do so slightly more efficiently than the other and therefore come to dominate in the long term. In temperate parts of the world, either trees dominate (in forests) or grasses dominate (in grasslands). Yet, in savannas grasses and trees coexist. The classic explanation proposes that trees have deep roots while grasses have shallow roots. The two plant types are therefore able to coexist because they are not in fact competitors: the trees increase in wetter climates and on sandier soils because more water is able to penetrate to the deep roots. Trees do indeed have a few small roots which penetrate to great depth, but most of their roots are in the top half-metre of the soil, just where the grass roots are.

Sequoyah, a Cherokee Indian, was born in about 1770 in Taskigi, now in Tennessee. Raised by his Cherokee mother, the young Sequoyah never learned to read or write English. While interacting with English speakers, he realized the necessity of a writing system for the Cherokee people. In about 1809, Sequoyah began developing a system of writing, adapting letters from English, Greek, and Hebrew. By 1821, he had created a system of 86 symbols, representing all the syllables of the Cherokee language. The Cherokee people began to use the system in their schools and publish books and newspapers in their language. In 1824, the General Council of the Eastern Cherokees awarded Sequoyah a medal in honor of his accomplishment. Sequoyah moved to Oklahoma some years later and died in what is now Texas in 1843. And later, people remembered him by naming a certain tree species "Sequoia."

If an animal is innately programmed for some type of behaviour, then there are likely to be biological clues. It is no accident that fish have bodies which are streamlined and smooth, with fins and a powerful tail. Their bodies are structurally adapted for moving fast through the water. Similarly, if you found a dead bird or mosquito, you could guess by looking at its wings that flying was its normal mode of transport. However, we must not be over-optimistic. Biological clues are not essential. The extent to which they are found varies from animal to animal and from activity to activity. For example, it is impossible to guess from their bodies that birds make nests, and, sometimes, animals behave in a way quite contrary to what might be expected from their physical form: ghost spiders have tremendously long legs, yet they weave webs out of very short threads. To a human observer, their legs seem a great hindrance as they spin and move about the web.

In 2001, researchers at Wayne State University asked a group of college volunteers to exercise for twenty minutes at a self-selected pace on each of three machines: a treadmill, a stationary bike, and a stair climber. Measurements of heart rate, oxygen consumption, and perceived effort were taken throughout all three workouts. The researchers expected to find that the subjects unconsciously targeted the same relative physiological intensity in each activity. Perhaps they would automatically exercise at 65 percent of their maximum heart rate regardless of which machine they were using. Or maybe they would instinctively settle into rhythm at 70 percent of their maximum rate of oxygen consumption in all three workouts. But that's not what happened. There was, in fact, no consistency in measurements of heart rate and oxygen consumption across the three disciplines. Instead, the subjects were found to have chosen the same level of perceived effort on the treadmill, the bike, and the stair climber.

In the summer of 1972, the actor Anthony Hopkins was signed to play a leading role in a film based on George Feifer's novel The Girl from Petrovka. That is why he traveled to London to buy a copy of the book. Unfortunately, none of the main London bookstores had a copy. Then, on his way home, waiting for an underground train at Leicester Square tube station, he saw a discarded book lying on the seat next to him. It was a copy of The Girl from Petrovka. As if that was not coincidence enough, more was to follow. Later, when he had a chance to meet the author, Hopkins told him about this strange occurrence. Feifer was interested. He said to him that in November 1971 he had lent a friend a copy of the book—a unique copy in which he had made notes on turning the British English into American English for the publication of an American version—but his friend had lost the copy in London. A quick check of the copy Hopkins had found showed that it was the very same copy that his friend had mislaid.

This is Mark Foster, one of the volunteers for the Auditory Frog and Toad Survey. Unfortunately, I was not able to participate in the orientation last weekend, so I could not receive training in distinguishing the sounds of frogs and toads. I heard from another participant that a CD was used in the training session. I was wondering if you could send me one. Since we have ten more days before the survey begins, I'll have enough time to receive and use the CD to train myself. You can send it to me at the address in my application. I am looking forward to hearing from you soon.

When she heard the dogs barking fiercely on the floor just above her, she trembled uncontrollably for fear of being caught. Drops of cold sweat rolled down her back. Before slipping into the hold of the boat, she had scattered powder, which Swedish scientists had developed, unnoticeably on the floor above in order to distract the dogs. But she knew that these dogs were so well trained that they could smell her, even though a load of fish had been dumped over her hiding place. She held her hands together tightly and tried not to make any noise. She was not sure how long she could stay like that. To her relief, it wasn't long before a whistle called the dogs out, leaving her unfound. She relaxed her hands and exhaled a deep breath. She felt safe now.

Have you ever met someone while you were experiencing significant emotional, psychological, or physical stress? Perhaps you stayed up all night studying for a final, or maybe you learned that a grandparent recently died. You likely exhibited behaviors that are not consistent with how you usually act. Meeting someone when you are extremely stressed can create an inaccurate impression of you. For this reason, recognize that our first impressions of others also may be perceptual errors. To help avoid committing these errors, engage in perception checking, which means that we consider a series of questions to confirm or challenge our perceptions of others and their behaviors. For example, see if you can provide two possible interpretations for the verbal and nonverbal behavior observed and seek clarification of it in order to determine the accuracy of your evaluation.

When we see a happy face (or an angry one), it subtly generates the corresponding emotion in us. To the degree we take on the pace, posture, and facial expression of another person, we start to inhabit their emotional space; as our body mimics the other's, we begin to experience emotional matching. Our nervous system is automatically set to engage in this emotional empathy. But how well we use this capacity is largely a learned ability. Animals－and people－who have been raised in extreme social isolation are poor at reading emotional cues in those around them not because they lack the basic circuitry for empathy but because, lacking emotional tutors, they have never learned to pay attention to these messages and so haven't practiced this skill.

When we hear a story, we look for beliefs that are being commented upon. Any story has many possible beliefs inherent in it. But how does someone listening to a story find those beliefs? We find them by looking through the beliefs we already have. We are not as concerned with what we are hearing as we are with finding what we already know that is relevant. Picture it in this way. As understanders, we have a list of beliefs, indexed by subject area. When a new story appears, we attempt to find a belief of ours that relates to it. When we do, we find a story attached to that belief and compare the story in our memory to the one we are processing. Our understanding of the new story becomes, at that point, a function of the old story. Once we find a belief and connected story, we need no further processing; that is, the search for other beliefs stops.

Max completes the tenth lap and now has five more laps to go. Max sees Simon's kart ahead, just out of Max's reach. Max's kart gets closer and closer to Simon's. It almost hits the back end of Simon's kart. They drive into the straightaway and Max presses harder on the gas pedal. "I can catch up," says Max. Max sees the official waving a white flag which means the last lap. Max is right behind Simon. The finish line is getting closer, and the cheering from the crowd is getting louder. "I can do it!" Max says loudly. He can feel his heart beating hard. The karts rush across the finish line. Who is the winner?

Max's eyes are filled with tears as he finds out that he came in second. "No need for tears, kid," says a man's voice. Max can't believe his eyes. The man who is standing in front of him is Richards! "Thank you, but I'm not the winner," says Max. "It was a real close race. Even though you didn't win the race, you did your best. That's the thing that counts" says Richards. 'Did I do my best？' thinks Max. After a moment, he smiles. "Yeah, I guess I did."

Wear your helmet in the right way, and check your bike before you ride it! According to a study, there is an 85% reduction in the risk of head injury if you wear a helmet properly. And checking your bike can prevent accidents from happening! CHECKLIST-Wearing a Helmet. The front edge should be two finger widths above the eyebrow. If it is too far forward, it can block your vision. If it is too far back, it does not give proper protection. The strap should be loose enough for you to comfortably breathe. But it should also be tight enough to keep your helmet on. Checking Your Bike. The tires should be firm. Make sure the brakes work properly.

Einstein, Dali, Leonardo Da Vinci, and Edison had one thing in common. They would take naps. However, they did so for different reasons. The former two believed micronaps gave them inspiration. A micronap puts you in the in-between stage where you are asleep but not sleeping deeply enough to dream. They would sit and sleep in their armchair holding a pencil or key. The aim was to wake up inspired just before falling into a deep sleep, to the sound of the dropped object. The latter two criticized people for wasting time sleeping. Leonardo thought sleep resembled death, and Edison believed sleeping for a long time was a sign of laziness. So instead of sleeping at night, Leonardo would take many short naps. And Edison napped during the day and only slept for a short period at night. *No matter what their method was, these men got energy from naps. Is taking a nap the key to success?

My family does spring cleaning annually. We decided to do it today because today's weather was warmer than yesterday. This year, our spring cleaning was very special. We used baking soda and vinegar instead of chemical cleanser. Amazingly, the effects were similar to those of chemical cleanser. We put some baking soda and vinegar on our dirty stove and bathtub. When we scrubbed them, the dirt came off easily without too much effort. After we finished, we felt good about using chemical-free cleaning products. We saved not only our planet but also our money!

In animation movies, amazing things are possible. But are they actually possible in real life? Let Down Your Hair, Rapunzel! In the animation, Rapunzel must lower her long hair to let people in her tower. But could human hair really hold up a person? Surprisingly, yes! A single hair can hold up 100g and an average head has about 120,000 hairs. All those hairs could hold up a couple of elephants! With her hair, Rapunzel has the ability to hold up a person. But she should wrap her hair around something strong and heavy. If she doesn't, she will get a very sore neck.

In the animation, monsters scare children to get energy from their screams. Amazingly, their city is powered by this sound! But could we actually produce electricity to light up a city from sound? Yes, sound can be changed into electricity. But it would not be helpful in our everyday activities because the amount is too small. For example, the sound from a car horn only produces 50 mv. That is only 1/4400 of the average 220v of electricity in our homes. So, we would need an unbelievable amount of screams to light up an entire city.

The house is lifted and flown by thousands of balloons in the animation. Could that actually work? Let's say that a house weighs about 50,000 kg. A normal balloon at an amusement park can lift about 14g. So we need about 3,570,000 balloons to lift up the house. We also have to think about the weight of the balloons themselves and the strings. Then, we need to add a few more thousand balloons. Now, the biggest challenge is pumping up all those balloons!

Max pushes his foot down hard on the gas pedal as he completes his sixth lap on the track. On the straightaway, Max pulls right beside the race's leader, Simon. Last year, Simon won many races, but Max's best result in a race was coming in fifth place. This time, he has a chance to finish second. But he isn't going to be satisfied with second place today. The winner gets to meet the world famous racer Richards! He doesn't want to miss the chance to meet his role model.

ILR3-503
The other day, I saw a TV program about eating raw fish. Seeing a live fish sliced and put on plate, I wondered if fish can feel pain. I did some research to find the answer. It turns out that experts do not agree on the matter. Researchers in Scotland did a study on Rainbow Trout. They looked at their behavior and concluded that fish do feel pain. On the other hand, researchers in the United States and Australia thought differently. Pointing out differences in brain structure, they said that fish don't experience pain like humans do. With studies reaching very different conclusions, we cannot be sure whether or not fish feel pain. But they can feel stress, so we should at least be careful when handling them.

Eugene Cernan was a respected American astronaut and the last man to walk on the moon. He traveled into space on three separate occasions. The first was as Pilot of the Gemini 9A mission in 1966. Then in 1969, he was Lunar Module Pilot on Apollo 10. Finally, he was Commander of the Apollo 17 mission in 1972. It was on this last mission that Cernan walked on the moon. He and another astronaut completed three separate spacewalks on the moon's surface. The research performed on the mission provided valuable information to scientists. However, the mission is most famous for what Cernan did just before leaving the moon. Wanting to do something special for his daughter Tracy, Cernan traced her initials, TDC, into the soil. Considering the fact that nobody has walked on the moon since Cernan, Tracy's initials may still be there today!

I just watched a television program about interesting tourist spots around the world. My favorite was Angel Falls in Venezuela. Last year, I visited Niagara Falls, and I thought it was amazing. But Angel Falls looked much more impressive. And it is much taller than Niagara Falls. In fact, at nearly a full kilometer, it is taller than any other waterfall in the world. I want to visit Angel Falls some day. It is much more difficult to get there than it is to get to Niagara Falls. However, I think the difficult journey would be worth it!

For a long time, scientists studying human facial expressions limited their research to six basic emotions. These were happiness, surprise, anger, sadness, fear, and disgust. Recently, though, researchers have been studying and giving names to more and more emotions. These newly labeled emotions, such as "happily surprised" and "sadly fearful," are combinations of the original six. Interestingly, they involve facial muscle movements of both of the "parent" emotions. So, for example, when you feel happy, you smile. And when you feel disgusted, you might move your nose. But if you feel "happily disgusted," you will do both. These studies have proven that humans are becoming more and more expressive.

What is the scariest place you can think of? Maybe it is a dark building. A haunted house would be even scarier. The empty town of Pripyat and the nearby remains of the Chernobyl Nuclear Power Plant are still more terrifying. In 1986, a reactor at the plant overheated and exploded. This released much more radiation than any other nuclear event had released before. Everyone in Pripyat had to leave right away. Today, only an empty city remains. There are hotels, apartment buildings, and even a Ferris wheel, but the only people there are a few brave tourists. Because of the radiation, they can only stay for a short amount of time. This strange silent environment makes Pripyat scarier than any other place you can visit!

However, the mission is most famous for what Cernan did just before leaving the moon. Wanting to do something special for his daughter Tracy, Cernan traced her initials, TDC, into the soil. Considering the fact that nobody has walked on the moon since Cernan, Tracy's initials may still be there today!

I just watched a television program about interesting tourist spots around the world. My favorite was Angel Falls in Venezuela. Last year, I visited Niagara Falls, and I thought it was amazing. But Angel Falls looked much more impressive. And it is much taller than Niagara Falls. In fact, at nearly a full kilometer, it is taller than any other waterfall in the world. I want to visit Angel Falls some day. It is much more difficult to get there than it is to get to Niagara Falls. However, I think the difficult journey would be worth it!

For a long time, scientists studying human facial expressions limited their research to six basic emotions. These were happiness, surprise, anger, sadness, fear, and disgust. Recently, though, researchers have been studying and giving names to more and more emotions. These newly labeled emotions, such as "happily surprised" and "sadly fearful," are combinations of the original six. Interestingly, they involve facial muscle movements of both of the "parent" emotions. So, for example, when you feel happy, you smile. And when you feel disgusted, you might move your nose. But if you feel "happily disgusted," you will do both. These studies have proven that humans are becoming more and more expressive.

What is the scariest place you can think of? Maybe it is a dark building. A haunted house would be even scarier. The empty town of Pripyat and the nearby remains of the Chernobyl Nuclear Power Plant are still more terrifying. In 1986, a reactor at the plant overheated and exploded. This released much more radiation than any other nuclear event had released before. Everyone in Pripyat had to leave right away. Today, only an empty city remains. There are hotels, apartment buildings, and even a Ferris wheel, but the only people there are a few brave tourists. Because of the radiation, they can only stay for a short amount of time. This strange silent environment makes Pripyat scarier than any other place you can visit!

While different colors are worn from time to time, it is normal for businessmen and politicians to wear either a red or a blue necktie. But does the color matter? Psychologists have suggested that it does. In one study, it was shown that the colors red and blue improve mental performance and make people more open to suggestions. Furthermore, red was found to be more effective when it comes to improving our attention to detail. Blue, on the other hand, was found to increase people's creativity. So it is important for businessmen and politicians to know the secret power of these colors. Indeed, they need to choose their necktie carefully.

Are you thinking about where to live? How about a truly unique place? If you love skateboarding but do not have time to go to a skatepark, then the Skateboard House in Malibu, California is just right for you. There is a skateboard practice area inside the house itself. But that is not all. The whole house—including the living room, the kitchen, and even the furniture and the walls—is designed to be skated on. If you consider natural light to be the most important thing in a house, you might like living in the Transparent House in Japan. Its glass walls make it almost completely visible to the outside world. Of course, the Transparent House would not be a good place to live if you value your privacy.

Recently, researchers at Princeton University started to wonder why monkeys don't speak to each other like humans do. It should be possible for monkeys to talk, because they have everything that is required physically. The researchers looked at how macaque monkeys' lips, larynxes, and tongues move when they produce sounds. They used the data they gathered, along with actual recordings of macaque's sounds, to create a computer simulation of a macaque voice. It wasn't difficult for the researchers to change these sounds into English words and sentences. This means that, at least physically, macaque monkeys are able to speak like humans. So why don't they? The answer to that can be found in the human brain. We can think about the physical parts like the tongue and lips as the "hardware" of speech. The circuits in the brain can be the "software" that makes vocal communication possible. Monkeys simply have not developed the right speech "software" in their brains. That's why they don't talk like we do.

Every morning Alex walks into a café and orders a cup of coffee. Can you imagine who serves him? A robot barista named Gordon! Thanks to rapidly robots like Gordon are appearing in our daily lives. Companies are excited about robot labor, because it is getting cheaper and more efficient. Some robots are used to do work in extreme environments like the deep sea. And drones delivering goods to our homes will be a common sight in the near future. Some people are worried about there being fewer jobs. But others think we will adapt to this brave new world with robots serving people everywhere.

Visitors love Alaska's vast, unique natural beauty. When you ask them if they would like to come back again, their answer is always yes! There are countless activities you can enjoy in Alaska. Day cruises at Glacier Bay National Park are especially popular. They allow you to view Alaska's fantastic coastal scenery and see abundant wildlife. As you look out onto the clean, blue water, you can see sea lions, seals, whales, and much more. Alaska also has more than 12,000 rivers and about 3 million lakes. Featuring more than 627 species of fish, it's a fisherman's paradise. So why not take your next vacation in Alaska?

Before the concert, I thought that the instruments might sound strange. After a few minutes, a group of young people began to walk on the stage. The first thing I noticed was their instruments: a cello made out of a shiny oil tank, a violin made with forks, and a flute made with a water pipe and buttons. The concert began with a girl playing Bach's Cello Suite No 1 on her shiny cello. I was shocked by the deep sound. I was so into the music that I forgot that they were playing with instruments made from recycled materials.

After the concert, I was eager to write a story about the orchestra. I met Favio Chávez, the conductor, and asked him about the orchestra. Lucy White: Why did you start The Junk Orchestra? Favio Chávez: When I went to a small town called Cateura in Paraguay to work on a recycling program in 2005, I saw children living in a town that was mostly filled with garbage. I wanted to add something positive to their lives, so I decided to share my love of music with them.
m3vk-404
Lucy White: Why did you use garbage to make instruments? Favio Chávez: One person's garbage is another person's treasure. Nicolás Gómez, a local garbage picker, helped me a lot. He made it possible for children to play music by making instruments out of garbage. The wonderful thing about these instruments was that the children didn't have to worry about spending a lot of money on them. Lucy White: What do you want people to learn through your music? Favio Chávez: I want people to know that even something worthless can make inspiring music. After interviewing Chávez, I realized that it really doesn't matter what instrument you play with as long as you put your heart into playing it. The children of Cateura showed me that an orchestra is formed by people, not by instruments.

During the summer, my friend Amber, who lives in London, turns the clocks forward by one hour. I asked her why. She said this practice is called "daylight savings time" or "summer time." Daylight lasts longer in the summer months and is shorter in the winter months. So people turn their clocks ahead to take advantage of the longer days. This is especially helpful for farmers, because it allows them to work outdoors for an extra hour. But even those who work on a "nine-to-five" schedule enjoy an extra hour of natural sunlight once they finish their day's work. I think it is a good idea to turn the clocks forward.

In 1946, a strange man visited me and asked, "Are you Mr. Kim Yonghwan's daughter?" For me, this was an odd question because I was more used to being called the daughter of a parakho. "I'm your father's friend. You may wonder if it is true, but your father," the man said. At that moment, I was expecting disappointing news since I did not have good memories of my father.
m3vk-302
Back in the 1920's, whenever people saw me in the village, they would say, "There goes the parakho's daughter." My father was a son from a very rich family. Instead of living the life of a seonbi, he was always at the gambling house. That is why he was called a parakho, which means someone who ruins his family's fortune. "Your father has gambled away all of the money, and now he's asking for more. Go and tell him that we have no more money left," my mother would tell me whenever she sent me to the gambling house. Then, my father would yell at me angrily, "Why did you come empty-handed? Bring me more money!"

When I was sixteen years old, my family had already made an arrangement for me to marry Mr. Seo. As part of the wedding tradition, Mr. Seo's family sent my family some money to buy a new chest for clothes. Right before the wedding day, my mother came into my room and said, "Your father has taken the money for the chest." I asked angrily, "How could he do such a horrible thing? What should we do now?" "We have no choice. You'll have to take your aunt's old chest," my mother said. "How embarrassing for the family," people would whisper behind my back. Since the first day of marriage, life at my husband's house had been difficult for me.

"Your father, my dear friend," my father's friend continued his story. "He was not a gambler. Your father sent the family money to the independence fighters in Manchuria. He made himself look like a gambler to keep this a secret from the Japanese officers." At first, I was not sure if he was telling the truth. But afterwards, I found out the truth about my father and I realized that I had been wrong about him. Ever since that moment, I have been proud to be the daughter of a parakho who had devoted his life to the independence movement.

Our school serves healthy and balanced meals. We usually eat a salad as an appetizer. Main dishes often include meat or fish. We also eat fresh fruit at the end of the lunch. Oh, I can never forget about baguettes! They're great with cheese. Our school also has a special rule. We must stay at the lunch table for at least 30 minutes. Bruno, Brazil Usually, we have beans and rice for lunch. Meat and vegetables are common in our side dishes. My favorite lunch comes with plantains. A plantain is a fruit which looks like a banana. We usually fry plantains. Our school lunches are fresh because the vegetables and fruit come from local farms.
