If you are human, you can't help but experience times when everything seems to be going wrong and you feel as if your life is completely out of control. It is during those “down times” that words of encouragement from family, friends, co-workers or even strangers can lighten your spirits. It is also during those times that destructive(有害的) words can sink you deeper and deeper into depression(沮丧).

    For example, consider this story about a group of frogs who were traveling through the woods when two of them fell into a deep pit（坑）. All of the other frogs gathered around the pit. When they saw how deep the pit was, they told the two unfortunate frogs they would never get out.

    The two frogs ignored the comments and tried to jump out of the pit. The other frogs kept telling them to stop. Finally, one of the frogs took heed of what the other frogs were saying and simply gave up. He fell down and died. The other frog continued to jump as hard as he could. Once again the crowd of frogs shouted at him to stop the pain. The more they shouted, the harder he jumped and finally he made it to safety.

    When he got out, the other frogs asked him why he continued to jump when they were all shouting at him to simply quit. The frog explained to them that he was a little bit deaf. He thought they were encouraging him the entire time.

    Every time you have a chance to say either something positive or negative to another human being, do choose the chance to say something positive! Don't let those opportunities get away from you. Your words have a large amount of power. Use them wisely. You really never know just how much they can mean to someone else.

    Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture？

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleeps fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey (冰球) final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning. Thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

    It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

    When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    As computers become more popular in China, Chinese people are more and more depending on computer keyboards to input Chinese characters(汉字). But if they use the computer too much, they may end up forgetting the exact strokes(笔画) of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their homework and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being used more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

    'When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it.'

    'I'm not in the mood to write when faced with a pen and paper.'

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, 'Chinese characters enjoy both practical and aesthetic (审美的)value. But those characters typed with computer keyboards only keep their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's feelings. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.'

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

"Cool" is a word with many meanings. Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings. 

"Cool" can be used to express feelings of interest in almost anything. When you see a famous car in the street,maybe you will say, "It's cool." You may think, "He's so cool," when you see your favourite footballer. 

We all maximize (扩大) the meaning of "cool". You can use it instead of many words such as "new" or "surprising". Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall (瀑布) they had visited. On one student's paper was just the one sentence, "It's so cool." Maybe he thought it was the best way to show what he saw and felt. 

But the story also shows a scarcity (缺乏) of words. Without "cool", some people have no words to show the same meaning. So it is quite important to keep some credibility (可信性). Can you think of many other words that make your life as colourful as the word "cool"? I can. And I think they are also very cool.
