It's just been three months after the first bike-sharing company arrived in Singapore, but reports of abuse and vandalism（故意破坏）of shared bikes in the city keep appearing on social media.

    The majority of these shared bikes are stationless, which means they don't need to be stopped at a designated（指定的）spot. They lock themselves after your ride is over, and you're meant to just leave the bike at the side of a road.

    But users have been chaining up bicycles outside their apartments, preventing others from using them. Some people bring them up to their apartment floors, so they can't be found easily by other users. Some people have removed the bikes' number plates or codes, and some even have painted over the bikes to claim the bikes for themselves. Most of the abused bikes belong to either Singapore-based oBike, or ofo, a bike-sharing giant based in China.

    ofo has encouraged Singaporean users to report issues. oBike said that the number of bicycles that were damaged made up less than one percent of its fleet. The company said in February that it planned to bring in “tens of thousands” of bikes by mid-2017. The company has yet to ban anyone from its service, but said that it would take appropriate action – including making reports to the police.

    oBike also introduced a shortcoming system, similar to that of its competitor, China-based Mobike. Users start with 100 points, which get taken away for errant（出格的）behaviour such as forgetting to lock the bike, or parking at non-designated areas. Users are banned from using oBike when their scores reach zero. oBike has an eight-man operation team that can remove bicycles parked casually.

    When approached for comment, Mobike said, “In China, just as in Singapore, there are always a tiny minority of people who abuse the bikes, so we designed our system to prevent this type of abuse.”

    The idea of turning recycled plastic bottles into clothing is not new. During the last five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution. But there's a problem with this method. Research now shows that microfibers could be the biggest source of plastic in the sea.

    Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years now. He explains that every time synthetic (合成的)clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can't collect these microfibers. So every time the water gets out of a washing machine, microfibers are entering the sewers and finally end up in the sea.

    In 2011, Browne wrote a paper stating that a single piece of synthetic clothing can produce more than 1, 900 fibers per wash. Browne collected samples from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.

    This is bad news for a number of reasons. Plastic can cause harm to sea life when eaten. Studies have also shown that plastic can absorb other pollutants.

    Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental "solution." Even though the science has been around for a while, Browne explains that he's had a difficult time getting companies to listen. When he asked well-known clothing companies to support Benign by Design—his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn't get a satisfying answer. Only one women's clothing company, Eileen Fisher, offered Browne funding.

    As a college student, I have planned my future career goals. I would like to work as a sales assistant in a computer company, then a sales manager and finally boss of my own company.

    At the very beginning, I plan to find a job in a famous company producing computers, in which all the staff are fully happy at work and I can experience job satisfaction most of the time. Only such kind of company can provide me with good working atmosphere and eagerness to learn more so as to get well prepared for my future profession.

    At first I want to be a sales assistant and always keep myself busy working in and out of the company, such as, answering telephones, doing repair work, even cleaning the rooms. Although the salary may be low, I will seize every chance to learn from other staff. In my spare time, I will take some courses so as to get more qualifications and experience in this field. In three or five years, I am determined to become a sales manager who is responsible for the selling of the computers. I will interview as many customers as possible and do market research and improve our products. Meanwhile I will take care of my staff to make them eager to work to the best of their abilities.

    As is known to us, it is hard to manage a company, but I will make every effort to achieve my goal step by step, and I am sure "There is nothing difficult in the world if you put your heart into it."

    Some people say summer is the time when teachers should get more pay. But not everyone is grateful to teachers for keeping kids occupied (无空闲的) between August and June: Washington state representative Liz Pike has written a Facebook post, titled "A life in the day of a WA state representative," and responded to teachers' complaints of rising costs of living. The post has received criticism for being anti-teacher. After reading her post, I feel that Liz Pike should rethink her criticism of public school teaching and avoid comparing it to the private school.

    Many of us teachers would certainly like teaching to be more like the private school. We see nothing wrong with fair pay for fair performance. In fact, performance is the name of the game. With standardized testing popular throughout K-12 education, teachers are some of the most analyzed and performance-measured employees in the United States. Liz Pike is very angry that teachers want raises even while test scores are dropping. Well, how are we supposed to have discipline (纪律) in the classroom when our hands are tied and we can hardly do anything with naughty students or fail students who are not prepared to move on to the next grade?

    Teachers would love to be able to turn education around and improve student performance. But we can't, and we should not suffer for it. Unlike private school businesses, public schools cannot turn away "customers". A private school business serves customers who walk through the door of their own free will, while public schools have to educate students who only attend because courts say they must.

    She says those who are "uninspired" by a lack of a cost of living increase should give up teaching. Is this the message that she thinks should be sent to the students whose academic performance she claims (声称) to care so much about? That "if you love it you'll shut up and not stand up for yourself"? I think teachers should stand up for themselves and I also think supporting teachers can make teachers teach children how to stand up for themselves.

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物) who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel(残忍的) to his clerk and turns away his only living relative. One night, Scrooge is visited by three spirits. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.

As I drove along the road, a small car flew across the center divider from the opposite direction and crashed into my car head-on, I fainted and was awakened by the ringing of my mobile phone.

I was brought to Kuala Lumpur General Hospital bleeding on from my nose, mouth and legs. But the hospital staff was too busy to attend to me, so I called a friend to tell him about the accident. Some friends arrived very soon and sent me to a private hospital nearby. I saw my injured feet hanging from my body, blue and lifeless, and I begged the doctors to save them at all costs. They calmly promised to do their best.

The doctors made it. After I was discharged, I was given ten months medical leave. My heart sank, knowing that it meant I, a big man, couldn't work. How was I going to support my 65-year-old mother and other family members? I felt completely helpless, but a lot of unexpected blessings came my way. I had many visitors during my 14 days in hospital and when I was recovering at home. Friends and relatives helped me with my banking, insurance or simply came to cheer me up.

When the casts (石膏) were removed, I did not let the sight of my weak legs discourage me. I worked hard at my physiotherapy (物理疗法) with only one aim. After eight months, I was walking without the aid of a walking stick. On February the following year, I returned to my job again. Today, after eight years, I have travelled to many countries as a tour leader.

The accident makes me realize how lives can change in a split second. I value life more, not only of my own but also of everyone I know, and I will always try to help when I know of someone in trouble.
