Chiang Mai is proud of the city's 700- year history, which has rich traditional relics and unique culture. It is located 700 km north of Bangkok and is situated among the highest mountains in the country. Chiang Mai means “the new city” in Thai. King Mengrai founded the city as the capital of the Lanna Kingdom on April 12,1296. Therefore, Chiang Mai not only became the capital and cultural center of the Lanna Kingdom, but was also to be the center of Buddhism in northern Thailand. King Mengrai , a very religious leader, founded many of the city's temples (寺庙) that remain important today.

    It is one of the few places in Thailand where it is possible to experience both historical and modern Thai Culture. The city has old temples next to modern stores. It has more than three hundred temples, among which some are the most beautiful and honorable in the entire Buddhist world, giving the city an atmosphere (氛围) of calmness.

    The old city of Chiang Mai has various dialects, architecture, traditional values, festivals, handicraft and classical dances. In addition, it has hill tribes and their wealth of unique culture. Chiang Mai city features old-world beauty and charm as well as modern enjoyment and convenience. It is also filled with natural resources including mountains, waterfalls and rivers. Nowadays there are many activities and attractions both in the city and the surrounding province, including river rafting , elephant riding and golf.

    The quality of living is excellent. Accommodation and food are of the highest standard at a very low cost. Entertainment is plentiful with numerous festivals, outdoor activities and great nightlife. A number of elephant camps, numerous outdoor activities, a variety of handicraft workshops, various cultural performances, and breathtaking scenery make Chiang Mai one of Asia's most attractive tourist destinations.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

    It's that time of year when people need to lock their cars. It's not because there are a lot of criminals running around stealing cars. Rather, it's because of good-hearted neighbors who want to share their harvest. Especially with this year's large crop, leaving a car unlocked in my neighborhood is an invitation for someone to fill it with zucchini（西葫芦）.

    My sister, Sharon, recently had a good year for tomatoes. She and her family had eaten and canned so many that they had begun to feel their skin turn slightly red. That's when she decided it was time to share her blessings. She started calling everyone she knew. When that failed, she began asking everyone in the neighborhood, eventually finding a neighbor delighted to have the tomatoes. "Feel free to take whatever you want, "Sharon told her. Later that day, Sharon found that her garden had indeed been harvested. She felt happy that she could help someone and that the food didn't go to waste.

    A few days later, Sharon answered the door. There was the neighbor, holding a hot loaf of bread. The neighbor smiled pleasantly, "I wanted to thank you for all of the tomatoes, and I have to admit that I took a few other things and hoped you wouldn't mind. "

    Sharon couldn't think of anything else in her garden that had been worth harvesting and said so. "Oh, but you did, "the neighbor said. "You had some of the prettiest zucchini I've ever seen. "

    Sharon was confused. They hadn't even planted any zucchini. But her neighbor insisted that there really were bright-green zucchini in her garden. Sharon felt curious and decided to go to see where the zucchini had grown. The two of them walked together into the backyard. When the neighbor pointed at the long green vegetables, Sharon smiled. "Well, actually, those are cucumbers（黄瓜）that we never harvested, because they got too big, soft and bitter for eating. "

    The neighbor looked at Sharon, shock written all over her face. She gulped（哽住）a few times, and then, smiling, held out the bread, part of a batch she had shared all over the neighborhood. "I brought you a nice loaf of cucumber bread. I hope you like it. "

    Crossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

    A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance(阻力), making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health problems. So, planning to sit for a long period of time? Don't keep your legs crossed.

    Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

    So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

    British children generally learn how to ride a bike at a young age. I am an exception to that rule. It's not my dad's fault—he tried to teach me. I remember cycling around the neighborhood. To be honest, though, I never saw the appeal. One of my earliest memories is falling from my bike and into some spiny(多刺的) plants. I definitely didn't want to repeat that.

    So I stopped learning. My dad wasn't going to waste his time teaching someone who didn't want to be taught. Time passed and I accepted that I couldn't ride a bike. It never affected my life in high school because I lived close enough to walk.

    I never felt like I was missing out until I couldn't go on a bike ride with friends in Byron Bay because I was only confident that I could go on a flat surface in a generally straight line. So when the opportunity came up to bike the wall of Xi'an, I wanted to prove to myself that I could do it and make up for missed time. So, with a friend who is very patient, I got on the bike. Instantly nothing came flooding back to me, I had absolutely no idea how to start! "Push off with one foot hard" was my instruction. It sounded simple enough but it just would not happen. Until something clicked and suddenly I was off, going in a straight line on a flat surface and managing to avoid the Chinese tourists who obviously found exaltation on my face.

    At 22 years old, I finally learnt how to ride a bike, and nothing can hold me back.

    Like any new ninth­grader on the first day of school, Joemar Class had ninth­grader emotion (情绪). He's not used to school in Hartford. He's used to going to school in his hometown of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso，"he said in Spanish.

    We first met Joemar in mid­October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm — Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16­year­old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz — the school's program director.

    "I see you have a new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day？"

    Then he met a couple of teachers.

    "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then, Levitz took him on a quick tour of the school before classes began — to her office, the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's a little worried," Guillermo said as we left. "But, at the same time, he's looking forward to it."
