Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.

    {#blank#}1{#/blank#} First, we have most of our dreams during REM (rapid eye movement) sleep. At this time, the brain is very active. Second, everyone dreams, even if we can't remember doing so when we awake. {#blank#}2{#/blank#} While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.

{#blank#}3{#/blank#} Some believe that our dreams are relevant to thoughts and feelings that we experience while we are awake. Many dreams researchers think that a dream about death, for example, is really about an important life change. {#blank#}4{#/blank#} A dream about teeth—especially broken or loose ones-may suggest stress or fear. Dreams in which you are flying often represent freedom or escape.

   Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling, for example, maybe you are angry. {#blank#}5{#/blank#}

There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.

    A. Dreams may be more important than sleep.

    B. Scientists do not know for certain why we dream.

    C. If he or she was scared then maybe you are terrified of something.

    D. Modern research can tell us some important things about dreams.

    E. There are three things you should pay attention to have a sweet dream.

    F. Finally, a part of our brain helps us to understand daily experience we have.

    G. Dreams about telephones are thought to be about giving or receiving messages.

    Every now and then, you may be struck with a difficult person at work or at home. What are some of the keys to empowering yourself in such situations? {#blank#}1{#/blank#} Keep in mind that these are general rules of thumb, and not all of them can apply to your particular situation.

    {#blank#}2{#/blank#} When you feel angry or upset with someone, before you say something you might later regret, take a deep breath. This will help you remember that you're in control of your emotions and feelings. Also, if you remain calm, the other person will likely notice and reflect on his or her behavior.

    Put yourself in their shoes. It's important to remember that we all have off days and times in our life when things are trickier. Instead of judging others' behaviors immediately, try to practice empathy. {#blank#}3{#/blank#} If you are sensitive to personality differences, you will be better able to handle diverse conflicts.

    Be frank with others. Some people are not very self−aware, so maybe you just need to tell them constructively what the problem is. For instance, if a colleague were making unkind comments, what would you do? {#blank#}4{#/blank#} They'll either be apologetic as they didn't realize it was a problem, or they'll make some excuse.

    {#blank#}5{#/blank#} If someone is behaving in a threatening way, either verbally or physically, then regardless of who they are, it's OK to walk away or say that you are going to put the phone down and that you will return when they have calmed down.

A. Keep your cool.

B. Handle aggression wisely and confidently.

C. Adjust your style when you communicate with them.

D. It won't hurt you to take them to one side, and ask them why.

E. You step back and reflect on how you would feel in his or her place.

F. Here are some tried and true methods of handling them quite effectively.

G. It's helpful to remember that most difficult people also have positive qualities.

    Are you planning to go to university? {#blank#}1{#/blank#}Perhaps you will be choosing the classes you want to take, finding accommodation and enrolling in other activities. However, if you go to university in Chile there is something extra you must do before you can begin.

    An essential part of starting university in Chile is the “mechoneo”{#blank#}2{#/blank#} Students beginning their first year at university are “welcomed” by the older university students. They are taken from their classrooms on an unknown day and blindfolded. The older students tear their clothes, cut their hair, and cover them in raw eggs and other disgusting things.

    {#blank#}3{#/blank#} This will be based on how well the students do the activities, and many students try very hard as they want to be the king or queen of the year. The older students then take away everything of the younger students and tell them they must go out onto the street and ask people for money. They will need to bring back a certain amount of money in order to be given their things back.{#blank#}4{#/blank#}

    During March it is common to see new university students all around town wearing ripped, dirty clothes and covered in paint and mess. But the “mechoneo” is increasingly a source of dispute and debate. Some students see it as an important tradition and a unique experience that help new arrivals get to know everyone.{#blank#}5{#/blank#} There have been campaigns to ban or soften it in favour of more “positive welcomes'', and student organizations in some universities have voted to end the “mechoneo” completely.

A. It is an ancient university tradition here.

B. The younger students are forced to do games in dirty places.

C. The “queen mechona” and “king mechon” are chosen that day.

D. They have to do games and take up challenges for a whole day.

E. But others find it abusive, like a form of bullying.

F. What do you think you need to do in the first few weeks?

G. The money is then used to have a massive welcome party at night-time.

How teens can stay fit

    Any type of regular, physical activity can improve your fitness and your health. {#blank#}1{#/blank#}

    Exercise should be a regular part of your day, like brushing your teeth, eating and sleeping. It can be in gym class, joining a sports team, or working out on your own. Keep the following tips in mind:

    {#blank#}2{#/blank#} A good attitude is important. Find an activity that you think is fun. You are more likely to stick with it if you choose something you like. A lot of people find it's more fun to exercise with someone else, so see if you can find a friend or family member to be active with you.

    Take it one step at a time. {#blank#}3{#/blank#} For example, walk or ride your bike to school. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator.

    Get your heart pumping (跳动). Whatever you choose, make sure it includes aerobic (有氧的) activity that makes you breathe harder and increases your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart work better. {#blank#}4{#/blank#} Examples of aerobic activities are basketball, running, or swimming.

    Don't forget to warm up with some easy exercises or stretching (拉伸) before you do any physical activity. {#blank#}5{#/blank#} It is also important to stretch out after you exercise to cool down your muscles.

A. It also burns off body fat.

B. Stay positive and have fun.

C. Make physical activity a habit.

D. Small changes can add up to better fitness.

E. The most important thing is that you keep moving!

F. This warms your muscles up and may help protect against injury.

G. Do the activity as often as possible, but don't exercise to the point of pain.

    We know that choosing a college major can be extremely hard. {#blank#}1{#/blank#}. However, it is a challenge to pick one when it feels as if the rest of your adult life is riding on that choice. It is a big commitment, but it's not a life sentence. Many graduates pursue careers that aren't directly related to their college majors, or change careers after several years. You may choose to base your decision on any of these factors:

    Dream job

    {#blank#}2{#/blank#}. Maybe you already know that you want to be a nurse, a day trader, a physician, or a web developer. Before you declare, take a class or two in the relevant discipline, talk to students in the department of your choice.

    Great ambition

    According to PayScale.com, the majors that lead to the highest salaries include just about any type of engineering, actuarial mathematics, computer science, physics, statistics, government and economics. Keep your quality of life in mind, too.{#blank#}3{#/blank#}.

    {#blank#}4{#/blank#}.

    Some students choose a major simply because they love the subject matter. If you love what you're studying, you're more likely to fully engage with your classes and college experience. {#blank#}5{#/blank#}. If your calling is philosophy, don't write it off just because you're not sure about graduate school, or what the job market holds for philosophers.

A. Love project

B. The academy of the School

C. Many schools offer hundreds of choices

D. Science is a specific subject that college students specialize in

E. That can mean better grades and great relationships with others in your field
