Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world. Built at almost 10,000 feet on the top of an Andean mountain, the Incas built hundreds of structures made of stone. A large number of Machu Picchu's surrounding structures date back to the early 13th century, but it was considered a chief sacred site far before then. The Inca people changed the large site into a very small but wonderful city, completely self-sufficient and hidden from below. Agricultural terraces (梯田) surrounded the entire city, fed by natural spring water, supporting the entire population.

Inca Trail

    The trail is one of the most famous in the world and regarded as one of the best. It covers only 26 miles, combining cloud forest, green mountain scenery, forest, and plenty of tunnels, paving stones, and ruins. The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape. The trail winds through the Andes, leading alongside and through ruins. Though independent hiking was once permitted, now it must be done with a guide.

Funerary Rock

    It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation, or mummifying (做成木乃伊), a common habit among the tribe. Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed. The rock is also famous as a spot from which a view of the city is afforded.

Temple of the Sun

    Within the city's castle, deep within Machu Picchu, is the Temple of the Sun, accessed only by the Emperor and

    Inca priests. It means the Inca's advanced knowledge of religion, weather, and nature, showing the great extent

    Incas went to adapt to and learn about nature. Still unbroken, the temple was built to honor the god Inti, who is exactly the sun. The temple was effectively protected. It was also a very important scientific center, built in half-moon shape with openings facing north and east. The windows' shadows in the center of the temple helped see the start of winter solstice (至日), showing farming season.

    She was walking home from work one evening when she got the idea. Rosa didn't like her job at the factory, but it was better than no job at all. So, while she was trying not to think about work, she saw the pots in an alley. They were cheap plastic pots, but there were dozens of them piled up behind the flower shop. Such a waste, she thought. When the pots were still there three days later, Rosa went in and asked if she could take some. The flower shop lady said she didn't mind, so Rosa carried home a tower of pots, pretending she was a circus performer on the way.

    At home, Rosa set them on the fire escape outside her tiny apartment. And there they sat. Once a gust of wind sent them slipping to the street three floors below, and she had to go to run after and catch them before the gathering storm.

    Every day, Rosa went to work and thought about her pots- She was wailing for something, but she had patience.

    At last, the newspaper brought good news. A hardware store had a sale on potting soil. Rosa carefully counted her money, then walked six blocks to the store. She bought six bags and carried them home. She bought seeds, too. Rosa slept well that night and dreamed of masses of flowers and fat, glowing fruits,

    Sundays were always good days. Rosa didn't have to work on Sundays. But Rosa couldn't remember when she had had such a good Sunday. She got up early and ate her breakfast on the fire escape with her pots. Then, she began to put dirt into the pots. She sang a little song until all six of her bags of soil were empty. Then, she laid her precious seed packets out and planned her garden. Tomatoes for the biggest pots, and peppers for the next-biggest ones. Flowers in all the rest.

    At the end of the day, Rosa sat in her garden and watched the sunset. Soon, she thought, there will be masses of flowers and fat, glowing fruits.

    Reuel Tolkien (1892 ~ 1973), the British linguist, writer. He created a fantasy novel “The Lord of the Rings”, the well-known trilogy (三部曲).

    Tolkien was born in Bloemfontein, South Africa. When he was 4 years old, his father died and his family moved back to England. Tolkien graduated from Oxford University when he was 23 years old, and participated in the First World War. During the war, Tolkien suffered from “trench fever” and stayed in the hospital until the end of World War I. It was the days in the hospital that he began his writing career first.

    After the war, Tolkien became a linguist. He was an edition of the “New English Dictionary” of 1918 ~ 1920. However, he was more researching to Anglo-Saxon language which makes his extensive contacts in Britain and the Nordic spread all over the folklore and mythology.

    In 1937, Tolkien completed his first work “The Hobbit”. Although this was a fairy tale, it was also suitable for adults to read. Because of good sales, publishers (Allen & Unwin) convinced Tolkien to write its sequel. This encouraged Tolkien to complete his most famous works the epic (史诗) trilogy “The Lord of the Rings”. The works of writing went on for almost a year with the support from his good friend Lewis.

    At the beginning “The Lord of the Rings” was similar works for children, but after that writing style quickly became serious and dark. “The Lord of the Rings” was one of the most popular literary works in the 20th century in terms of sales and readers' evaluation. Tolkien's influence is important, for the success of “TheLord of the Rings” makes the fantasy novels of this literature genre (体裁) developed rapidly.

    Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.

    Harmer, a professor in the University of California at Davis, Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.

    By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.

    The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably track the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.

    When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day or on the other side at night. A plant growth-regulating hormone (激素), called auxin, appears to be a key driver.

    The “dance” to the sun cycle obviously slows when the sunflower matures (成熟) and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.

    “Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.

    “The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said “We're currently testing this idea.”

    New study shows that when teachers participate in a training program focused on prosocial (亲社会的) classroom behavior, their students are better able to control their emotions, and that children who can regulate emotions are more likely to be academically successful.

    For the study, which appears in Prevention Science, researchers looked at more than 100 teachers and 1,817 students from kindergarten to third grade to see if teachers could support students' emotional and behavioral growth through the Incredible Years Teacher Classroom Management (IYTCM) program.

    The program uses videos and training sessions, along with role-playing and coaching, to help teachers learn management skills such as using behavior-specific praise, building positive relationships with students, and considering how to reduce poor behavior. Teachers in the training group increased interactions with students by 64 percent compared with 53 percent for teachers in the control group without the training.

    "Emotional regulation is the ability to recognize what behavior is appropriate in the present situation," says Wendy Reinke, professor in the College of Education at the University of Missouri. "For example, a student might have difficulty controlling the feeling of anger if he or she becomes annoyed with another student. But under this program, the teacher encourages them to move to a different spot in the classroom, effectively teaching them that sometimes stepping away and taking a break is a good way to calm down and manage8ha8feeling."

    After one school year of using the program in classrooms, students improved their social ability and ability to regulate their emotions. These improvements resulted in an increase in the tests for students in Incredible Years classrooms vs. students in control classrooms. And this classroom management approach can help reduce the risk for struggling learners early on, which could help prevent more accumulative support needs in a child's future.
