I look around and can't recognize where I am. It seems familiar but distant. I see my friends gather by a stage where music is playing and I run over. As I begin running towards them, they become further and further away. I keep calling them, but no one hears me. I start hearing a distant alarm-like sound and I am transported away. I woke up in a daze sitting in my bed.

    “Oh, it was only a dream,” I said to myself. I have always had vivid and intense dreams. It feels like I haven't even slept because I have been living out my dreams during my sleep.

    Today, dreaming is being studied even more than ever. Some say that dreams are how your receptors make sense of random thoughts while you sleep. Some say that you can't dream of a face you have never seen before, so everyone you see in your dreams you have at least laid eyes on at one time or another.

    Other people think dreams are ways of expressing stress or internal feelings you may be experiencing. A lot of people say that they have dreams about being chased.

    A common interpretation of the “being chased” dream is that you are feeling threatened. Some dream interpretation websites say you should try to reflect on what or who is chasing you to get a better idea of what is making you feel this way.

    Another dream that is often experienced is flying. This dream has a much more positive interpretation, which is that you are feeling free or have broken out of a bad situation such as a relationship turned sour or a job you hate.

Unfortunately, you may forget half of your dream within five minutes of waking up and within 10 minutes, you usually forget 90 percent of it.

    Dreamologists, people who devote time to the study and interpretation of dreams, suggest if you want to try to remember and study your dreams you should keep a journal beside your bed and write down what you dreamt as soon as you wake up so you can reflect on it later.

    Some people think the government should move the big companies and factories in cities to the countryside. To what extent do you agree?

    Due to the increased urbanization, there appears a bunch of heated social problems. Some people have noticed that there are many big companies and factories in the city and they believe that moving those big companies and factories into countryside could be a good way to solve many of the city problems, such as traffic issues and housing problems. However, I hold an opposite opinion to them and I will explain it as below.

    Cities have much more advantages than countryside. There are more cinemas, restaurants and shopping malls in cities, let alone better education and health care. Living in cities makes life more convenient and enjoyable. Thus not everyone is willing to move to countryside in spite of their companies' moving. They have got cars, which transfers them easily between work and home. Therefore, the pressure of traffic will not be released due to such solution. As for the available empty places spared by the big companies, the newest small companies will take good care of them—with the realization of the benefits that running a business in cities will bring to them. In other words, situation of housing will not be improved much.

    Besides, there will be more problems if big companies and factories move out. Where there are big companies and factories, there will be cities sooner or later. Consequently, countryside is to be disappearing. What's more, industrial pollution is not an easily mended problem.

    In conclusion, moving big companies and factories out of cities is never a final solution. It tackles(解决) no problem but causes lots of them. Just imagine. The traffic is still terrible, and there is no more scenic countryside. We should look into other ways to solve the problems.

    Now many young people are traveling around the world on their own，not because they have no one to travel with，but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries，with no one to help you read a map，look after you if you get ill，or lend you money if your wallet is stolen，it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website，The Aussie Nomad，to document his adventures. He says he wished he had traveled alone earlier. “The people you meet，the places you visit，or the things you do，everything is up to you and it forces you to grow as a person，” said the 30-year-old man.

    Richardson describes traveling alone like "a shot in the arm"，which "makes you a more confident person that is ready to deal with anything". He said，"The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said，"Only by going alone in silence can one truly get into the heart of the wilderness."

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize (强调) the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries -- like the UK or France -- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    Sports can help us a lot. Taking exercises can make us strong. In collective（集体的）sports like basketball, volleyball or football, we will learn the importance of cooperation(合作). And sports can also help us relax after work or study.

    However, as the saying goes, "there are two sides of everything." Sometimes we may hurt other players or ourselves if we are not careful enough when participating(参加) in sports activities. What's more, too much or hard practice can be bad for our health.

    Sports can make us healthy both physically and psychologically(心理地). It is also a good way for people to know each other and can improve friendship between people. So long as we are careful enough, sports can do us nothing but good.

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you fall asleep with.

    If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people. So you never express your real feelings. You're quite shy and you aren't very confident.

    If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not tomorrow.

    If you sleep curled up(卷曲), you are probably a very nervous person. You have a low opinion of yourself and you often protecting yourself from being hurt, so you are very defensive. You're shy and you don't usually like meeting people. You prefer to be on your own. You're easily hurt.

    If you sleep on your side, you have usually got a well-balanced(平衡的) personality. You know your strengths and weaknesses. You're usually careful. You believe in yourself. You sometimes feel anxious, but you don't often get unhappy. You always say what you think, even if it makes people rather angry.
