With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama's(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

    All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” —— the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

    Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金）(our kindergarten daughter is serious about becoming a doctor)

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

    When you were at school, the last thing you probably wanted to do was spend your weekends going to work. There was homework to do, sport to play and fun to have. But our parents probably persuaded us to find a job to earn some money and get some life experience. When I was a teenager I had a paper round: delivering newspapers to people's homes. I then progressed to a Saturday job in a supermarket: stacking shelves and working at the checkout.

    Today in the UK you are allowed to work from the age of 13, and many children do take up part-time jobs. It's one of those things that are seen almost as a rite of passage (成人仪式). It's a taste of independence and sometimes a useful thing to put on your CV (简历). Teenagers agree that it teaches valuable lessons about working with adults and also about managing their money.

    Some research has shown that not taking up a Saturday or holiday job could be deleterious to a person later on. A 2015 study by the UK Commission on Employment and Skills found that not participating in part-time work at school age had been blamed by employer's organizations for young adults being ill-prepared for full-time employment, but despite this, recent statistics have shown that the number of schoolchildren in the UK with a part-time job has fallen by a fifth in the past five years.

    So, does this mean that British teenagers are now afraid of hard work? Probably not. Some experts feel that young people feel going out to work will affect their performance at school, and they are under more pressure now to study hard and get good exam results-and a good job in the long term. However, Geoff Barton, general secretary of the Association of School and College Leaders, told BBC News that “Properly regulated (控制的) part-time work is a good way of helping young people learn skills that they will need in their working lives." In reality, it's all about getting the right balance between doing part-time work and having enough time to study and rest.

    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."

    Anyone who is afraid of failure and afraid to face challenges will never taste success, so said our professor in marketing. I laughed it off at that time, but got frightened when it actually happened in my life.

    I landed in a small city in the Middle East to set up a firm, a world－class car rental firm. Having decided on the project, I earnestly settled in preparation. With a positive mind, I told myself nothing should stop me now, and was more than keen to make it a success.

    However, the least expected thing happened. Iraq invaded Kuwait. Tension ran high in the region. Eventually the war broke out, and many people fled the country, leaving my firm in deep trouble.

    As usual, "things become difficult, and every effort seems to bring disappointment, it can be tempting to lower your expectations or even water down your goals and ambitions." I was no exception. I thought of running away. I remembered the words of Thomas Edison, "Many of life's failures are people who did not realize how close they were to succeed when they gave up."

    I decided to hang on, telling myself, "I am not afraid of challenges and obstacles." I stayed on through months of uncertainty and insecurity. Finances ran low, and banks could not wait to get their dues. To add to all this, the banks even threatened to take all my vehicles. I felt I made a wrong decision to move there. I was now ready to face failure.

    I was living against all hopes, believing that something good would happen. After 2 months the war ended. My persistence paid off: people started flooding back and the car bookings picked up, five times over.

    Success comes to the one who dares, even after failure, to think positively and look forward confidently. After all, it is only the experience that makes a man tough. Failure does not mean you will never make it. It means that it will take a little longer. It provides us with a learning experience.

    It has been described as art by some people, but to others it's an ugly part of modern life. What is it? Graffiti (涂鸦), of course. Look around cities in the UK today and you can see graffiti on buildings, walls, doors and even on buses or trains that have stayed in one place for too long. But where modern technology creates a problem, it also finds a way to deal with it. Last week, The Weekend West was shown around the factory of a small but successful company, Hubdean.

    Hubdean's achievement is a series of special paints which are graffiti-resistant. How do they work? It couldn't be simpler. Take any graffiti-covered surface. First, a treatment called Agproclear is used. Then, using a very hot pressure jet (压力喷嘴), this treatment is taken away and the graffiti disappears at the same time. Now you have a clean wall. But before this clean wall can be painted on by graffiti lovers, a new product, Agproshield, is used. This paint has a special surface which gives it two important advantages. Firstly, spray paint (喷雾颜料) won't stick to the surface very well, and secondly, the whole surface can be cleaned very easily, just using water. Once the surface is painted, no specialist equipment is needed to keep the area clean and graffiti-free.

    Not surprisingly, Hubdean's products are used by both local governments and private companies all over the UK, and now orders are being received from around the world. This brings the company a problem, however. Can they increase production to satisfy the needs? Of course, they can build a second factory or work with a large international company to make their products. The future is looking good for Hubdean!
