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.

    “We haven't found anything that we can't recycle!”

    Cigarette ends are everywhere—littering our streets and beaches—and for decades they've been thought of as“unrecyclable”. But a New Jerseybased company, called TerraCycle, has taken on the challenge, and has come up with a way to recycle millions of cigarette ends and turn them into industrial plastic products. Its aim is to recycle things that people normally consider impossible to reuse.

    Obviously it would be even better for the environment if everyone just stopped smoking, but the statistics show that although there has been an increase in anti-smoking ads and messaging, between 2000 and 2014, global sales of cigarettes increased by 8 percent, and a whole lot of those cigarette ends are ending up as trash. Since most of our litter eventually ends up in waterways, cigarette ends can surely pollute the surrounding environment. “It only takes a single cigarette end to pollute a liter of water, ” TerraCycle founder, Tom Szaky, said. “Animals can also mistake littered cigarette ends for food.”

    So how do you go about turning all those poisonous ends into something useful? TerraCycle does this by first breaking them down into separate parts. They mix the remaining materials, such as the tobacco and the paper, with other kinds of rubbish; and use it on non-agricultural land, such as golf courses. The filters (过滤嘴) are a little harder. To recycle these, TerraCycle first makes them clean and cuts them into small pieces, and then combines them with other recycled materials, making them into liquid for industrial plastic products.

    They're now also expanding their recycling offerings to the rest of the 80 percent of household waste that currently can't be recycled, such as chocolate packaging, pens, and mobile phones. The goal is to use the latest research to find a way to stop so much waste ending up in landfill (垃圾填埋), and then get companies to provide money for the process. And so far, it's working.

    “We haven't found anything that we can't recycle,”communications director of Terra Cycle, Albe Zakes, said. “But with the amount and variety of packaging and litter in the world, we are always looking for new waste streams to address.”

    I am astonished at the way God knows when to send a special gift of encouragement at just the right time! It might be in a dream, a lost letter, a memory, or something found that we'd forgotten about.

    My grandmother was from a town in Michigan. And summer after summer I enjoyed staying with my grandparents as a young child. I was from the city and loved the small town where they lived. People knew everyone, their children, their pets, their ancestors.

    Grandma was always using her hands for something exciting …She would make sandwiches and we'd have tea parties, plant flowers and carefully tend them. She loved knitting sweaters as well as making beautiful quilts　for her grandchildren. I remember the small thimble ( 顶 针 ) she would place on her finger while doing her needlework.

    A few years ago, when Grandma left this earth for her new residence in Heaven, I bid farewell to my loving grandmother. How quickly our lives can change! We had just had tea together a couple of months earlier, on her 91st birthday. I missed her very much, but I noticed it mostly on my birthdays, because there was no card from Grandma. She'd never forgotten my birthday!

    On one particular birthday when I was feeling a little low, something happened and made me feel as if she was sharing that special day with me. I was arranging some colorful pillows that she had made, and suddenly I felt something inside one pillow; it was small and hard. I moved the object to a seam (缝) that I carefully opened, and, to my delight, out came a tiny silver thimble!

    How happy I was to find something that had been a part of her! Not realizing k had fallen off her finger, I pictured her sewing h into that little pillow that I just happened to fluff (抖松), to place on my bedspread (床罩) that day. I carefully laid the thimble alongside the others Id collected over the years. What a precious memory of a very special lady who, somehow, I knew, was laughing in delight at sewing her thimble into my pillow. I heated the kettle and made some tea, using my best china, as Grandma always did, and then enjoyed my tea and Grandma's thimble. What a wonderful birthday that was!

    My husband David was waiting at the door when our daughter Laura and I came back. It wasn't like him to be home so early. The disbelief on his face told me that something was up.

    "Do you still have a job?"

    "No. Redundant," he answered, looking away from me.

    "OK. We'll figure it out," I replied calmly. I actually had no idea how we were going to figure it out. I immediately started to think of how we'd cut costs and who we should start to get in touch with. That night, after David had fallen asleep, I cried myself to sleep, and frequently sobbed（抽泣） in the shower in the days that followed.

    I knew the loss of David's income would have great effect on us. He had worked for the same company for twenty﹣one years and was our main income. I work at home caring for Laura, and my income is uncertain. We have debts, and job hunting takes time.

    Still, I was more concerned about my husband's emotional state than our financial situation. David's sense of identity was tied to his job. He called his parents to tell them about losing his job, but didn't say a word to anyone else for weeks. He told me that he felt like "a failure".

    It was tough for me to watch David struggle with unemployment. One night several weeks after he lost his job, David woke me just before midnight, sweating, pacing the bedroom floor and saying he didn't feel well. We spent the night in the emergency room waiting to see if he had a heart attack. Thankfully, it was just a serious anxiety attack. It was then that I knew I needed to do more to understand what my husband was going through. Here is what I learned from my own experience﹣and from talking to experts﹣on how to support your loved ones through a job loss.

    Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly where she's been while she's on her worldwide vacation in a special way. The traveler, who was born with a bone disease, had her right leg amputated (截肢) at the age of four. Although the amputation caused inconvenience for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.

    To spread that message. Gallagher has gone to social media, where she shares photos of her travels across the world, but instead of simply using a geo-tag (地理位置标签), she writes her location on her artificial leg before taking a picture.

    Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the beautiful Parthenon temple in Athens and enjoying a river ride in Budapest, all with the well-known locations written on her artificial leg.

    "I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board," Gallagher said. "My mum and grandmother didn't like the idea, but my friends thought it was great and told me to go for it, so I did."

    Gallagher said people often stare when she's writing on her leg, but once she shares the photos, she receives only positive feedback (反馈), "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, anyway, I've been able to keep up with people at my age and lead a pretty great life."

    Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.
