What Will Be Done-With All This Denim?

    All the denim (牛仔布) will be donated to Cotton From Blue to Green, which recycles jeans into UltraTouch Natural Cotton Fiber Insulation (纤维隔热材料), which is used to help build houses in places that have been damaged by hurricanes and other natural disasters. Your jeans will help keep clothes out of landfills (垃圾场), and build houses for families to live in! UltraTouch is made of 85% recycled fibers and is an environmentally safe, natural cotton fiber insulation.

It's a Fact

    It takes about 500 pairs of jeans to recycle enough denim to insulate one average-size U.S house.

Here's How You Can Get Involved!

1). Get a parent's permission and select as many denim jeans as you like. (Any denim clothing is OK)

2). The denim must be used.

3). The denim can be any brand.

4). The denim can be any color or size but must have been worn by a human (no doll clothes!).

5). Jeans must be received by June 30, 2017.

    The world seems gloomy (阴沉的) and gray when you're feeling blue. In fact, being down might even affect how you perceive (感知) the colour blue. A recent study about colour was published in the journal Psychological Science. It shows a direct connection between a person's ability to perceive colour and their emotions.

    Psychologists have long known that emotions can affect the way people perceive things. That's in part because chemicals from your brain might affect how you process what you see. “Color is such an important part of our experience,” says lead author Christopher Thorstenson, a psychologist at the university of Rochester, in New York. There's reason, he says, that sad people commonly describe the world as “colourless” and “gray”, and happy people use words like “bright” and “colorful”.

    In the experiment, the researchers randomly assigned people to one of two groups. People in the sadness group watched a sad scene from The Lion King. Those in the “amusement” group watched a comedy.

    Everyone was then asked to look at red, yellow, green, and blue patches (斑点) that had been changed to a grayish colour. “Some of the patches are pretty difficulty to make out,” Thorstenson admits he says it takes some time to figure out their shade. People were scored on how accurate their colour perception was. Then they completed an emotional evaluation.

    The result? Sad people had a hard time seeing the difference between shades along the blue-yellow colour axis (色轴). But they did not have problems seeing colours in the red-green spectrum (光谱). Thorstenson says this could be the result of an evolutionary need to see red as a response to anger.

    Thorstenson says these results highlight the possible important of dopamine in sight. Dopamine is a chemical that sends signals to the brain. Researchers are hoping to focus more on dopamine in the future. “We know dopamine affects how we see colours, too,” Thorstenson says “How we feel can really influence how we see the world around us” he says.

    The National Day holiday is a great opportunity to do something a little different. Many people use the National Day for a getaway, a short trip to leave the stress of their everyday lives behind and explore, learn, or relax.

    Hotel Romance

    Many hotels and resorts feature something special to start the getaway, such as champagne, flowers, or a fruit basket in the room on arrival. Getaway packages usually include a room with something special, a heart shaped bed, for example. Additional benefits could be room service meals or other private dining, plus tickets or discounts for local attractions.

    Visit a Spa

    Spa getaways can take place at a location that focuses only on spa services or at a hotel that offers a spa as one of its features. Some spas emphasize treatments fit for their geographic area or a local attraction. A spa in a grape growing region might provide grape juice masks, or a hotel near a hot spring could offer mineral baths. Most spas offer a range of massage, health and beauty treatments, so a spa getaway can be relaxing with other benefits.

    Learn a Skill

    The National Day holiday may not be enough time to become an expert at something new, but it provides a way for people to begin their explorations. Some organizations offer intensive courses that last five or six days. People with special interests can get away from their routines while learning such things as how to make beer, speak a new language, or take better photos.

    Help Others

    Some organizations cooperate with businesses to have accommodations and activities for short-term volunteers. Most volunteer vacations involve ecology friendly or charity activities. A volunteer getaway is a way to relieve stress and help others at the same time.

    Stay in a National Park

    For those who want to relax in a rural environment, a national park fits the bill. Most national parks provide camping areas for tents and trailers. Several have cabins within the parks available to rent. A getaway to a national park provides privacy, stress relief, and the time to get to know some important natural resources.

    As smog forced students to stay home, the online learning industry saw a sharp increase in consumers.

    During the air pollution red alert from Dec. 8 to 10 last winter, the Beijing Commission of Education ordered all kindergartens, primary schools and middle schools to suspend classes (停课). But the commission urged that, "Teachers should guide students to make full use of digital materials and conduct online learning at home".

    According to the China Education and Research Network, the number of new users of 17zuoye. com, an online homework platform, tripled (增至三倍) on Dec. 8 compared to the previous day.

    Online courses companies also adopted special measures to meet students' demand for Internet learning during the red alert period. For example, New Oriental offered free online English classes for three days for school students as well as online question answering services.

    Recent years have seen the popularity of online courses increase sharply in China. Massive Online Open Courses (MOOC), for example, originated in the United States but have become widespread in China since 2013. Some Chinese universities, including Tsinghua University and Peking University, have started their own MOOC platforms. "MOOCs have enlarged the time and space of teaching, fired up learners' interest, helped more people benefit from high quality educational resources and accelerated reform in many aspects of teaching," an official at the Ministry of Education told China Daily.

    Plants are living things. So can they feel pain? Plants don't feel pain the same way animals and people do, says Anke Steppuhn. She is a scientist at the Free University of Berlin in Germany. "What we define as pain usually has to do with a nervous system," Steppuhn explains. When you put your hand too close to a hot stove, nerve cells send a signal to your brain. Your brain decodes (解码) that signal as pain. This causes you to pull your hand away before any serious damage is done.

    Plants don't have nerves or brains, so they can't feel pain like we do. "But plants do recognize when something is hurting them," Steppuhn says. Because they are rooted to the ground, they can't escape a dangerous situation. So they need other ways of fighting back.

    The biggest threat to a plant's life is getting eaten. Some plants grow sharp little hairs. Other plants produce bad-tasting or even harmful chemicals. These force an attacker to abandon its meal. A plant called bittersweet nightshade does something even smarter, Steppuhn found. When a slug (蛞蝓) chews holes in a nightshade' s leaf, liquid begins dripping (滴) around the wound. It is almost as if the plant were bleeding. The liquid is sugary nectar (花蜜), and it happens to be a favorite food of ants. In their effort to collect the nectar, the ants swarm (蜂拥而至) all over the injured plant. They will attack anything that stands in their way. That includes the slug that damaged the plant in the first place. It's a very clever trick. Whenever a slug attacks a plant, the plant calls an army of ants to kill the slug.

    Nectar isn't the only way plants attract bodyguards. They also release certain chemicals into the air when they are being eaten. People usually can't detect these smells. But wasps (黄蜂) can. When a wasp detects this cry for help, it races to the scene of the crime. If it finds the right kind of insect chewing down on the plant, the wasp will interrupt the attacker's meal. It will do this by laying eggs inside the insect's body!

    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.
