Eighteen years ago, Terry Grahl, was pregnant with her fourth child. “Money was very tight,” Terry recalls. So when her mom called to ask if she'd like to go shopping at the local fabric(布料) store for the coming Christmas, she couldn't say no because she knew she badly needed some fabrics to make new clothes for her children. “I remember walking around, gazing at all this beautiful fabric, wondering whether there is anything cheap that I could afford. And I could still get some money left to buy Christmas gifts for my family.

    Well, Terry's mom must have known what Terry was thinking. Smiling kindly, she whispered to Terry, “You pick any fabrics you like. It's your Christmas gift from me.” Terry's eyes were filed with tears as the cart began to overflow with many fabrics, but not because Terry was planning on making herself a pretty dress or a pair of curtains for the kitchen. Rather, Terry's mom's kindness had inspired some holiday gift ideas in Terry, and it didn't take long for Terry to figure out what she was going to do with all that fabric.

    “I was going to make my first quilt,” she explains. “Every night I would work on this queen-size quilt. With every stitch(一针), I thought about all that my mom had done for me over the course of my childhood, during which we were always battling homelessness, but Mom somehow managed to fill our lives with love and make everything okay.”

    On Christmas Day, five days after her baby girl was born, Terry handed her mom a gift box. Inside was the quilt she had sewn, from the fabric her mother had given her as a gift.

    Location:

    Washing to National Cathedral | 3101 Wisconsin Ave NW Washing ton, DC

    YouthCUE Festival of Youth Choirs in Washington gives students the rare opportunity to perform in the Washington National Cathedral, a famous historic place. The festival is a showcase of student choirs from all over the country, accompanied(伴奏)by musicians from the local professional orchestra(管弦乐队).

    The horse I'm riding is named Candy, which is appropriate, taking account of her love for eating. As we go our way down the mountain of Big Bend National Park, Texas, I'm sweating—half due to the hot weather, half due to an effort to stay on the horse. Candy, however, is relaxed and stops to eat cactuses (仙人掌) as she passes. She is used to the dusty trails through hills and canyons(大峡谷) and ignores my attempts to guide her away from her delicious food. Our ride becomes a battle of will, which Candy wins easily. I comfort myself by admiring the views across Big Bend's wide open spaces.

    Texas only national park, Big Bend, extends across 800,000 acres of the Chihuahuan Desert, in the deep southwest of the state right along the border with Mexico. It is named after the U-turn that the Rio Grande River makes here. It has seen a lot of fights. The Spanish, Anglo-American settles, Mexicans, and Apache and Comanche American Indians all fought to rule this place.

    Our group member, Mike, knows every corner of the park and describes it as “sort of a secret place”. Even some Texans don't know about Big Bend, he says. Other local people describe it as a forgotten national park. Compared with the almost five million travellers that descend on the Grand Canyon every year, only 30000 make it here.

    There are six of us in the riding group, all fairly inexperienced, led by tour guides, Linda and Janelle, who keep both us and the horses in line. We trek along the top of an 800-foot mountain, with wide-winged eagles flying beside us. The air is noiseless.

    The park is fantastic for hikes and has a variety of marked walking paths. The walk is a five-mile round trip. While the final stretch is rather steep, the views over giant canyons and plains are worth the effort.

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置)well after they go out of style. That's bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life—from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992.Digital cameras arrived on the scene in 1997.And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones.“The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007.We're not just keeping these old devices—we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放)more than doubling during the 1992 to 2007 window.

    So what's the solution (解决方案)?The team's data only went up to 2007,but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

    The greatest recent changes have been in the lives of women. During the twentieth century there was an unusual shortening of the time of a woman's life which was spent in caring for children. A woman marrying at the end of the 19th century would possibly have been in her middle twenties. They would be likely(可能) to have seven or eight children and four or five of them lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years. During the twenty years, chances and health made it unusual for her to get paid work.   

    Today women marry younger and have fewer children. Usually a woman's youngest child will be fifteen when she is forty five and is likely to take paid work until they are sixty. Even while she has to take care of children, her work becomes easier by eating fast foods and using washing machines , cleaning robots and so on.

    This important change in women's way of life has only recently begun to play a role in their position.   Even a few years ago most girls left school at the first chance and most of them took a full- time job. However, when they married, they usually left work at once and never returned to it. Today the school -leaving age is sixteen. Many girls stay at school after that age, and though women are likely to marry younger, more married women stay at work at least until their first child is born. Many people return to full or part-time work after that. Such changes have caused a new relationship in the family, with both the husband and the wife accepting a great share of the duties and satisfactions of family life, and with both the husband and the wife sharing more equally in supporting the family, according to the abilities and interests of each of them.

    Throughout history scientists have risked their health and their lives in their search for the truth.

    Sir Isaac Newton, the seventeenth century scientist, was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, nothing long-lasting did. On another occasion he stared at the sun for as long as he could bear, to discover what effect this would have on his sight. Again he escaped suffering permanent damage, though he had to spend some days in a darkened room before his eyes recovered.

    In the 1750s the Swedish chemist Karl Scheele was the first person to find a way to produce phosphorus (磷). He in fact discovered eight more chemical elements including chlorine (氯), though he didn't get any praise for them. He was a very clever scientist, but his one failing was a curious habit of tasting a little of every substance he worked with. This risky practice finally caught up with him, and in 1786 he was found dead in his laboratory surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.

    Eugene Shoemaker was a respected geologist. He spent a large part of his life studying craters (火山口) on the moon, and how they were formed, and later did research into the comets of the planet Jupiter. In 1997 he and his wife were in the Australian desert where they went every year to search for places where comets might have hit the earth. While driving in the Tanami desert, normally one of the emptiest places in the world, another vehicle crashed into them and Shoemaker was killed on the spot. Some of his ashes (骨灰) were sent to the moon aboard the Lunar Prospector spacecraft and left there — he is the only person who has had this honor.
