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.

    Matthew Youlden speaks nine languages fluently and understands more than a dozen more. {#blank#}1{#/blank#} When I told Matthew how I've been working hard to only pick up a second language, he had the following advice for me.

    Know why you are doing it

    This might sound easy , but if you don't have a good reason to learn a language, you are less likely to stay interested over the long-run. {#blank#}2{#/blank#} Wanting to get to know a French person in his or her own language is another matter entirely. No matter what your reason is, once you've decided on a language, it's important to carry out .

    {#blank#}3{#/blank#}

    Matthew learned several languages together with his twin brother Michael. They learned their first foreign language, Greek, when they were only eight years old! Even if you can't get a sister or brother to join you on your language adventure, having any kind of partner will push both of you to always try just a little bit harder and stay with it.

    Have fun with it

    {#blank#}4{#/blank#}Think of some fun ways to practice your new language: make a radio play with a friend, draw a comic strip, write a poem, or simply talk to whomever you can. If you can't find a way to have fun with the new language, chances are you aren't following step four.

    Act like a child

    We learn by making mistakes. {#blank#}5{#/blank#}But as adults, mistakes become taboo(禁忌). Think how an adult is more likely to say, “I can't”, rather than, “I haven't learned that yet” (I can't swim, I can't drive, I can't speak Spanish). When it comes to learning a language, admitting that you don't know everything is the key to growth and freedom.

A. Find a partner

B. Leave your comfort place

C. We work in the same office in Berlin.

D. As kids, we are expected to make mistakes.

E. You are learning a language to be able to use it.

F. Using your new language in any way is a creative act.

G. Wanting to impress English-speakers with your French is not a very good reason.

    Speaking in public is most people's least favorite thing. The reason is that we are all afraid of making fools of ourselves.{#blank#}1{#/blank#}

    But stop biting your finger-nails. Public speaking is easy. It's just plain talking, and you talk all the time. Although I'm basically shy (honest!), I've been making speeches and talking on radio and television for more than 30 years, and I can tell you that public speaking is not a “gift” like musical talent.{#blank#}2{#/blank#} Here are some of the lessons I have learned:

    Your audience is going to come away with one or two of your main ideas. One or two. Not ten or 20.{#blank#}3{#/blank#} And if you don't have a clear idea of what you want to say, there's no way your audience will.{#blank#}4{#/blank#}— how you are going to open, what major points you want to make and how you're going to close.

    When I do a radio or TV piece, I often write the last sentence first.{#blank#}5{#/blank#} A strong close is critical: the last thing you say is what your audience will most likely remember.

    The standard length of a vaudeville (杂耍) act is usually 12 minutes. If all those performers singing and dancing their hearts out couldn't go on longer without boring the audience, what makes you think you can?

A. Some people are born to be good at making speeches.

B. Anybody who can talk can speak in public.

C. Try to relax yourself before making the speech.

D. The more important the speech is, the more frightened we become.

E. If you can't express in a sentence or two what you intend to get across, then your speech is not focused well enough.

F. When you know where you're headed, you can choose any route to get there.

G. No matter how long or short your speech is, you've got to get your ducks in a row.

    Follow these steps and you'll be getting to bed earlier before you know it.

    {#blank#}1{#/blank#}

    If you're currently going to bed at 11 pm, don't decide that tonight you're going to get to bed at 9 pm. But more generally, it's also important to give your body time to adjust as you start changing your bedtime. So you should take smaller steps.{#blank#}2{#/blank#}Write down your new bedtime.

    Set up your environment to avoid objections.

    What you'll need to do is to think through your specific plan, and identify potential objections.{#blank#}3{#/blank#}Imagine your routine for this evening, think through any possible obstacles and decide on specific ways that you'll avoid them.

    Set reminders for yourself to stick to your plan.

    {#blank#}4{#/blank#}The idea here is that reminders not only alert you in the moment, but they also help you build tiny habits for certain behaviors.

    Decide what time you're going to begin the process of getting ready for bed. Add it to your calendar.

    Make a public commitment.

    Making a public commitment to getting something done is a great way to create responsibilities for yourself.{#blank#}5{#/blank#}Decide what time you're going to go to bed tonight and find friends to tell them what time you're going to bed in case you miss your bedtime.

A. Make a change gradually.

B. Studies show that once we make it, we are more likely to honor it.

C. Remind yourself to go to bed as early as possible tonight.

D. Decide to go to bed 15 minutes earlier tonight than you usually do.

E. Make sure you get success in one time when you plan to change your bedtime.

F. Once you've mapped out a plan for your evening, you can set reminders for yourself.

G. The idea is to design your environment to make it less likely that you'll give up your plan.

What If We Don't Get Along?

    Teachers want to get along with you and enjoy seeing you learn. But teachers and students sometimes have personality clashes（人格冲突）. {#blank#}1{#/blank#} If you show your teacher that you want to make the situation better, he or she will probably do everything possible to make that happen. Take these steps if the problem seems difficult to solve:

    ⒈Talk to an adult you trust, such as a parent, guidance counselor, or both.

    ⒉{#blank#}2{#/blank#} You may not feel immediately comfortable with your teachers, but that may change as you get to know one another.

    ⒊If you've given it time, talk with your parents about what to do next. Lots of times, a meeting can be set up to discuss the problem. {#blank#}3{#/blank#} Everyone's goal should be to create trust and kindness.

    Your relationship with your teachers is often your first chance to develop a “business relationship”. They are different from your family relationships and friendships, which are built on affection and love. {#blank#}4{#/blank#} But they don't necessarily need to be good friends or like each other a lot. They simply need to respect one another, be polite, and stay focused on the jobs at hand.

    When you act this way, and remember that you're not the only kid in the class, you are helping your teacher. {#blank#}5{#/blank#} Teachers also like it when students follow directions and when they learn and obey the rules of the classroom. For instance, there may be rules about listening when another student is talking, about taking turns, or about raising your hand when you want to say something or ask a question.

A. Give it time.

B. This can happen between any two people.

C. This may clear the air and make things better.

D. Your teacher is likely to notice this and appreciate it.

E. Therefore, those teachers rarely show respect towards their students.

F. A teacher cannot necessarily answer all the questions his students ask.

G. In a business relationship, both parties get something out of the relationship.

    What will you do if you can't eat everything bought in the canteen? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people.

    {#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people.

    Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the West, for instance, consumerism, the belief that it's a good thing to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#} Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil others go through in order to provide them with the food they eat.

    {#blank#}4{#/blank#} There are over 925 million hungry people in the world, most of whom live in underdeveloped countries and areas. They don't have enough food to eat. Many children die for lack of nutrition each year in some African countries. And farmers work very hard to grow the crops. {#blank#}5{#/blank#} It's also important that everyone should think about how they can do their bit to reduce food waste.

A. Students' waste is extremely serious.

B. China, in turn, features its own eating culture.

C. But canteen waste is extremely the tip of the iceberg.

D. Students can never realize the serious food crisis.

E. Compared with them, some live in a different world.

F. So there's no excuse that we should waste our food.

G. Most of us would simply throw away any leftover food.
