If women are mercilessly exploited（剥削）year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion,they are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is capable of standing in front of a wardrobe（衣橱）packed full of clothes and announcing sadly that she has nothing to wear.

    Changing fashions are nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who cannot afford to throw away clothing in this way,waste hours of their time altering（政变）the dresses they have.Skirts are lengthened or shortened;neck-line are lowered or raised,and so on.

    No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth,comfort and durability（耐用）.They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort,as long as they look right.There can hardly be a man who hasn't at some times in his life smiled at the sight of a woman shaking in a thin dress on a winter day,or delicately picking her way through deep snow in high-heeled shoes.

    When comparing men and women in the matter of fashion,the conclusions to be drawn are obvious.Do the constantly changing fashions of women's clothes,one wonders,reflect basic qualities of inconstancy and instability （不稳定）?Men are too clever to let themselves be cheated by fashion designers.Do their unchanging styles of dress reflect basic qualities of stability and reliability（可靠）?That is for you to decide.

    Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?

    In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.

    Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.

    What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health.)

    Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.

    One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

    After the sudden loss of her 5-year-old daughter, Elizabeth, Natalia Spencer felt she needed to do something to honor the little girl. That strong wish inspired Spencer to start what she calls a “Walk of Love”, a 6,000-mile trek (长途徒步旅行）along the British coastline.

    “Elizabeth particularly loved the beach and the sea and we visited the seaside a lot. After she passed away, I went to the seaside and it was the first time I had felt some comfort,” Spencer said. “I knew this was what I had to do. It was something I could do and it would somehow make life more bearable.”

    On Valentine's Day, Spencer began walking Durdle Door in Dorset, England, the last beach she took Elizabeth to before she became ill. So far, Spencer has journeyed about 1,500 miles, walking through Dorset, Cornwall, Devon and the entire coast of Wales. Every day, except Saturday, Spencer walks 20 miles. Often locals join her; many times they share stories about losing their own children.

    Everything changed for Spencer on Nov. 22, 2015. Spencer noticed Elizabeth was ill with what she thought—was a chest infection. But the girl's health worsened rapidly. Doctors diagnosed her with a life-threatening immune condition where the immune cells damage tissue and organ. This caused Elizabeth's organs to shut down and stopped the blood supply to her arms and legs. She was moved to Bristol Children's Hospital where she spent 18 days on life support before passing away on Dec. 10.

    After Elizabeth died, Spencer struggled. She stayed with friends because it felt too hard to live in a house with the memories of Elizabeth. In January, a friend encouraged Spencer to go for a walk and the two ended up at the Gower Peninsula in Wales. That's when she realized she wanted to walk along the coast for her daughter.

    While walking provides Spencer with time to grieve (感到悲痛)，she's also using the trip to raise￡100,000(about $144,000) for the Bristol .Children's Hospital. She admired the doctors and nurses and wanted to raise money to allow another family access to treatment.

    Spencer expects to complete her walk next spring. She'd love to finish on Valentine's Day, but doesn't know if that is realistic.

    If you are worried about the planet, please make sure your rubbish is buried under the ground.

    People talk about "reduce, reuse, recycle." It sounds like a good idea. There is a problem, though. Recycling costs too much money.

    Even the U.S. Environmental Protection Agency (EPA) says it only makes sense economically and environmentally to recycle about 35 percent of disabled (废弃的) materials. Among those materials are paper and aluminum(铝) cans. Recycling 1 ton of paper or aluminum cans, the agency says, can save about 3 tons of CO₂ emissions (排放物) over producing those materials anew. Paper producers pay for the trees they process. If it was cost-effective to recycle paper, producers would be beating down your door to buy it. But they aren't. That means it's more expensive to recycle old paper than to cut trees and then replant trees for processing.

    Plastic can be recycled too. Given the recent drop in crude oil (原油) prices, it is now cheaper to make a new plastic container than to recycle an old one. Even if that were not true, the EPA says that recycling a ton of plastic saves only about a ton of CO₂. However, it doesn't take into account the water most consumers use to wash their plastic containers before having them recycled. The New York Times journalist John Tierney recently wrote, "If you wash plastic in water that was heated by electricity, then the effort of your recycling could be more carbon in the atmosphere."

    Glass is another recyclable material. To reduce greenhouse gas emissions by 1 ton you have to recycle 3 tons of glass. If one includes the cost of collecting glass waste from neighborhoods, and the pollution produced by the collection trucks and the recycling process itself, glass recycling creates more greenhouse gas emissions and is more expensive than making new glass, which comes primarily from sand that exists everywhere.

    If recycling were truly cost-effective, private companies would be lining up at your doorstep to buy your rubbish. Don't look now because they're not there.

    News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world's first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.

    Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax — and her reactions change as she continues reading. That's why many news anchors were worried: Will AI replace us in the near future?

    To find the answer, we have to analyze the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the AI news anchor reads, the micro- electric motors behind her face move to make her expressions seem more human.

    Yet we need a thorough knowledge of deep learning technology to make a robot imitate a person's voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text for the AI to learn and read. The process for imitating facial movements is similar. The developer has to analyze the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to learn, and imitate the movements of facial muscles via programs

    Both the technologies used to make Xin's performance impressive are mature. The real difficulty lies in the third — the technology to match the pronunciations with facial movements so that Xin's expressions vary according to the content of the news report. In fact, Xin's expressions don't always change according to the content. As a result, her expressions look anything but human. Actually, AI is still no match for human qualities.
