Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most adults sleep only seven or eight hours.{#blank#}1{#/blank#}All parts of our bodies have to rest after they work.. Our arms need a rest after we lift heavy thing, When we run fast, our legs work hard. They get tired. We have to rest them. Our brains workhard, too.{#blank#}2{#/blank#} We can sit quite still and rest our arms andlegs. But our brains aren't resting. They go right on thinking as long as weare awake.

      Our brains slow down a bit when we sleep and dream.{#blank#}3{#/blank#} Instead of thinking wide-awake thoughts, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of thetime we forget them when we wake up.

      Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night too,and the day after. They played games, but they made mistakes. They forgot things.{#blank#}4{#/blank#} The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. When they sat down, they fell asleep.

Scientists have found that if people are not allowed to sleep and to dream, they act in an unusual way.{#blank#}5{#/blank#}But we do know that we need it to stay well. So tonight have a goodsleep. Lie down under the covers. Shut your eyes. Let your thoughts wander.Soon you'll stop thinking. You'll be asleep.

    “How far is the next village？” the American asks a man standing by the edge of the road. In some countries, because the man realizes that the traveler is tired and eager to reach his destination (目的地), he will politely say “Just down the road.” He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling “being tricked”. He thinks the man on purpose lied to him, for obviously he must have known the distance quite well.

    Had conditions been reversed (颠倒过来), the American would have felt he was “cheating” the driver if he had said the next town was not too far, and if he would be sorry to the weary driver, he would say “You have a good way to go yet, it is at least fifteen miles.” The driver might be disappointed, but he would know what to expect.

    Whether to be accurate or polite leads to many misunderstandings between people of different cultures. If you know the situation in advance, it is sometimes easier to recognize the problem.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

We're often told "laughter is the best medicine".Laughter is ancient and instinctual,and a fundamental part of everyday life—something most of us enjoy naturally.There are comedy channels on TV,comedy festivals and our favorite funny friend who's sure to get our giggle on.

So why do we need laughter experts?Surely they're for people who can't laugh for whatever reason.However,while the ability to laugh is innate,the decision to activate and use it to its full ability is a choice.

When life gets stressful;illness creeps in;relationships are put to the test or we're struggling financially,there's rarely much to laugh about.So,we don't.Yet turning into the lighter,more humorous side of life,and activating one's "laughter self" is critical to mental health.Rather than waiting for something funny to happen or for life to be a bed of roses,we can transform our emotional state by tapping into our laughter and humor resources.This helps create distance between us and our pain and improve our moods and resilience(恢复力) to stress.It provides relief and release from some of the stress that has embedded in our bodies and minds,freeing ourselves to power forward,even a little.

Ironically,because laughter is an innate and largely unconscious behavior,it's rarely given much thought.As it's seldom thought about,it can't be that important.

Wrong.If laughing is a more complex behavior,my belief is people will pay greater honor to it,rather than something to laugh off.It's actually one of the most complicated things our bodies process.It is a vocal means of communication before language forms and the brain has fully developed.The vast majority of us maintain the ability to laugh until our final curtain falls,even amid declining cognitive function.

Turning toward the healing power of humor and laughter assists with personal and professional resilience,performance and overall well-being.No joke.
