The world consumes hundreds of billions of single-use plastic bags each year. They are difficult to recycle, wasteful and damage the nature. Environmental activists want to ban plastic bags or—as many communities have done —charge a fee for them. But the plastic bag industry defends their use, saying people reuse plastic bags, and industry officials argue recycling is a matter of personal responsibility and should not be forced.

    City officials say New Yorkers use 5.2 billion plastic bags each year. They are offered free with nearly every supermarket, or convenience store purchase. Many people like them, even if they sometimes feel guilty about using them. But what happens to those bags after they've been used in a huge environmental problem. They are found on beaches. They are caught in trees. They are swallowed by marine life.

    Plastic bags are made of petroleum products and natural gas, and do not biodegrade (分解). And they are difficult to recycle. So New York City spends nearly $ 10 million dollars a year to send 100—thousand tons of plastic bags to landfills out of state.

    In Washington, D.C., a five percent charge on all single-use bags led to about a 60 percent reduction and in Los Angeles County in California , a 10 cent charge on single-use bags led to a 95 percent reduction. With a 10 cent charge on bags, customers are much more likely to stop and think about whether they need a bag or not. And that's really all that these laws are doing.

Dearest darling girl,

    Today is the beginning of the next stage in your life. We head off to your new home at Stanford. Where do I start in telling you how proud I feel to be called Mummy by you? We've laughed at how you burst into this world with a scowl on your face, how determined you have always been right from feeding yourself to making big decisions for your life. There were days during your illness that I wasn't sure you had the will to make it. Telling you that you needed to want to get better was the hardest and yet the greatest day. From that day you took responsibility and decided you wanted to beat anorexia（厌食症）．

    I don't think I've ever felt so proud of you as when you came home to say that you wanted to go to West Africa between school and university. You chose to go alone, and to raise the money yourself. You have such strength of character and determination. It is at times hard to believe that you are only 18. You experienced something in that month that few dare experience in a lifetime.

    So, Viv, here are my words of wisdom to you as you start your next big adventure. The world is a beautiful place but often a few things can make it seem difficult. God's temple is made of love. It's man's temple that is built of stones. Open your heart to goodness and never ever let negative people or thoughts take hold of you. As Minor Myers put it, "Go into the world and do we'll. But more importantly, go into the world and do good:'

    It is true that with every passing day, I will grow older and weaker. A day may come when I will become forgetful. But even then, you with your bright smile, will light up my heart.

    Like many children, young Lotte Reiniger was crazy about movies, which at the time were a completely new invention. She taught herself how to cut paper silhouettes（剪影）, of people, animals, and objects. I could cut silhouettes almost as soon as I could manage to hold a pair of scissors, Reiniger said. “I could paint, too, and read...But everybody was surprised at the scissor cuts”

    At first, Reiniger wanted to be an actress, but her skill at making silhouettes drew the attention of the German film industry. Before 1927, films were silent. To help the audience understand the film, title cards with printed text appeared during the film between scenes. Reiniger helped create title cards for films, using her silhouettes. In 1918, she was asked to provide stop-motion animation（定格动面）, in which objects are photographed（拍摄）in a series of slightly different positions and then replayed at high speed so that the objects appear to move on their own, for wooden rats（老鼠）in the movie The Pied Piper of Hamelin. It was a breakthrough that led to her own films, first short films and then, in 1926, The Adventures of Prince Achmed, the first full-length animated film.

    Although Reiniger once described herself as “a primitive（原始的）caveman artist”, her work is not simple. She carefully cut bits of card, paper, and wire, creating wonderful shapes, and then made them move and dance by hand. The black shapes were then placed on colorful backgrounds. She made more than 60 films, around 40 of which survive, all cut by her own hands. Most were based on timeless fairy tales, like Cinderella and Sleeping Beauty.

    Reiniger was truly a pioneer both in animation and for women in film-making. Though her last film came out in 1980, her style is still influential and can often be seen in today's films.

    In today's working world, the high school diploma program has become the initial footstep in achieving a successful career. A high school diploma is a formal document issued to certify a candidate's successful completion of a prescribed (规定的) secondary school program of studies.

    It takes four years to complete the high school diploma program. The eligibility (合格) requirements for the high school diploma vary from state to state. A high school diploma is the minimum qualification for higher education and government jobs in the United States. The opportunities for a better job are extremely limited for one who has not earned a high school diploma. To be more specific, the high school diploma can qualify one for fruitful careers in science, education, health care, the travel industry, and the legal profession.

    In some states, high school diplomas are differentiated by type such as a general diploma, an academic diploma, or a vocational diploma. A high school diploma is regarded as the minimum admission requirement for post-secondary education programs. When people apply for a green card or a US visa, a high school diploma is a valuable asset for immigrants into the United States.

    There are several ways to achieve a high school diploma. One can get the diploma through traditional classroom study. It is best suited for individuals who enjoy face-to-face interaction with their teachers and classmates. In the United States, opportunities are provided for getting high school diplomas without attending classes at school. One can earn a high school diploma at home through a combination of online and correspondence classes.

    Generally, the high school diploma programs do not have minimum age requirements. In order to get the high school diploma, the students must complete the coursework dictated by their school district. Curriculum (课程) varies from district to district. Before enrollment, a student counseling (咨询) service is recommended to most students.

    Having a smart phone may not be as smart as you think. They may let you surf the Internet, listen to music and take photos wherever you are…but they also turn you into a workaholic（工作狂）,it seems.

    A study suggests that, by giving you access to emails at all times, the smart phone adds as much as two hours to your working day. Experts found that British people work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study shows the average UK working day is between 9 and 10 hours, but 2 more hours is spent responding to or sending work emails, or making work calls.

    Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers say they are on call almost 24 hours a day. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night. The average time for first checking emails is between 6 a.m and 7 a.m, with more than a third checking their first email in the period, and a quarter checking them between 11 p.m.and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said: “The ability to access millions of Apps has made smart phone invaluable for many people. However, there are disadvantages. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smart phones mean that people cannot get away from work. The more frequently in contact we become, the more is expected of us in a work capacity.”

Narayana Peesapaty was sitting on a flight when he noticed a passenger trying to reach food with a biscuit after breaking his spoon. At that moment, the researcher's mind gave birth to a simple yet revolutionary concept — edible spoons.

How do you like your spoon?

Peesapaty's company, Bakeys, makes edible spoons mainly out of sorghum(高粱）though rice, wheat and water are also ingredients. They combine to form a dry eating tool that remains hard even when used in moist or hot foods. Bakeys also makes ginger and garlic flavored(风味) spoons to meet specific requests. All spoons are completely natural and acceptable for nearly all diets.

A rice replacement

An environmentally-minded water researcher, Peesapaty, designed his spoons to be eco-friendly in several ways. Sorghum was chosen as the main ingredient of the spoons instead of rice, which requires 60 times as much water. Sorghum was also chosen for the strength it would lend eating tool, and the grain requires little water, low energy and no chemicals to grow.

In place of plastic

The goal that Peesapaty hopes to attain through Bakeys is to prevent plastic from any contact with food. Plastic products can contain cancer-causing substances that come into food, and average plastic bottles take 450 years to break down. In contrast, a Bakeys' spoon is nutritious and break down in 10 days or less if thrown away. Peesapaty admits that using plastic is cheaper, but he also says that his spoons will be equally inexpensive when mass-produced.
