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#}

    Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving (铺砌) a road can lead to less useable fresh water. {#blank#}1{#/blank#} Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.

    {#blank#}2{#/blank#} Drier climates are of course more likely to have droughts（干旱）than areas with more rainfall, but, in any case, good management can help to make sure there is enough water to meet our basic needs.

    {#blank#}3{#/blank#} In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.

    {#blank#}4{#/blank#} To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机) only when it is full. {#blank#}5{#/blank#} You can even help to keep our water supply clean by recycling (回收) batteries instead of throwing them away.

    {#blank#}5{#/blank#}

    Stress can result from disorganization and a feeling that “there's so much to do, and not enough time”. Trying to take care of everything at once can be too much for you and, as a result, you may not achieve anything.

    That's why dogs make such a hit. They are so glad to see us that they almost jump out of their skins. {#blank#}1{#/blank#}.

    A baby's smile has the same effect. Have you ever been in a doctor's, waiting room and looked around at all the sad faces waiting impatiently to be seen? There were six or seven patients waiting when a young woman came in with a nine-month-old baby. She sat down next to a gentleman who was more than a little impatient about the long wait for service. The baby just looked up at him with that great big smile that is so characteristic of babies,{#blank#}2{#/blank#}. Soon he struck up a conversation with the woman about her baby and his grand-children and then the entire reception room joined in, and the boredom and tension were changed into a pleasant and enjoyable experience {#blank#}3{#/blank#}. Telephone companies throughout the US have a program called "phone power" which is offered to employees who use the telephone for selling their services or products. In this program they suggest that you smile when talking on the phone. Your "smile" comes through in your voice.

    Your smile is a messenger of your goodwill.{#blank#}5{#/blank#}.To someone who has seen a dozen people frown or turn their faces away, your smile is like the sun breaking through the clouds Especially when someone is under pressure from his bosses, his customers, his teachers or parents or children, a smile can help him realize that all is not hopeless that there is joy in the world.

Customs on either side of the Atlantic

    We all know that Britain and the US are two countries connected by a common language. But in fact, {#blank#}1{#/blank#} as BBC did in a recent story called 8 Situations When Britons Behave Differently From Americans. Below Teens has picked out four for you. Take a look.

    When someone knocks into you.

    Britons don't all change into evening dress for supper like what you may have seen in popular TV shows like Downton Abbey. But they do tend to make an effort when going out for dinner somewhere nice. Americans, however, will probably wear a casual shirt to a fancy eatery.

    When you drift finish your food.
