What is a fair wage? {#blank#}1{#/blank#} These are some of the questions the United Nations International Labour Organisation(ILO) has recently investigated.

    With a global population of over seven billion, is it actually possible to measure an average amount? {#blank#}2{#/blank#} Using the total wage bill from over seventy countries, they have multiplied the amounts by the number of earners in each country. The economists then tallied up the results and divided them by the total number across the world The result was a world average wage equivalent to $1,490 a month. {#blank#}3{#/blank#} 

    This figure might seem very high because they calculated the amount using purchasing power parity dollars, which takes into account the fact that it is cheaper to live in some countries than others. {#blank#}4{#/blank#} 

    Calculating an average sum like this might not be a completely fair representation, but these figures do help us to understand how the world is developing, both economically, in the quality of life people are experiencing and their standard of living.

    But the result shows that the average wage is still relatively low and there remains a huge difference in levels of affluence around the world. {#blank#}5{#/blank#} Is this fair? For many, pay equality still seems very far out of reach.

A. The ILO has now tried to work out the sums.

B. The ILO used statistics from over 70 different countries

C. Why aren't more people in the world offered pay equality?

D. That is approximately $75 a day for a 20-day working month.

E. Some people live on just two dollars a day, while others are earning more than a million dollars a year.

F. When someone works for themselves, what are they called?

G. The data also did not include the huge number of people who appear in poverty statistics or who are self-employed.

    Everyone has heard of Groundhog Day (土拨鼠日).{#blank#}1{#/blank#}.

    People in America think that the groundhog awakens from its winter's sleep on February 2^nd. The groundhog comes out of its hole. If the sun is shining, it will see its shadow. The shadow scares it. So it runs back into its hole. This means six more weeks of winter. If the day is cloudy, it will not see its shadow. Since it is not scared, it stays out of its hole.{#blank#}2{#/blank#}. These are the same things we say on Groundhog Day today.

    {#blank#}3{#/blank#}They are known mainly to country people. City people just don't know how to look for them. City people think that a groundhog sitting by its hole may look like a root(根). It could also be seen as a clod (块) of earth. Or it may look like a broken fence-post(栅栏柱). But a farmer sees groundhogs anywhere he looks. They'll be watching like guards.

    The groundhog is a native American.{#blank#}4{#/blank#} It may also appear as far north as Alaska. It is hated by farmers. The groundhog eats a third of its weight in a day. What a big appetite(胃口)！It may eat about a half-ton of alfalfa(苜蓿) in a summer. So 10 groundhogs in a big field would eat five tons.

    Why do groundhogs eat so much? To prepare for winter.{#blank#}5{#/blank#} .This extra food is changed to fat. This fat is what they live on during their long winter's sleep.

    In lesser-developed countries there is less equipment for clean water and public health.If you can't avoid unhealthful water,make sure you bring along a tea or coffee—making pot that will boil water for you.You'd better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

    Enjoy the smell of roadside stands,not the food.

    Being a teenager can be tough. “Troubled” and “rebellious(叛逆的)” are often labels that people give kids in their teens. There are even scientific theories explaining that the likelihood of teenagers taking is due to the fact that their brains aren't fully developed yet. {#blank#}1{#/blank#}

    But a new study by researches at the University of Pennsylvania and Cornell University may have finally cleared up this misunderstanding. {#blank#}2{#/blank#}They simply are easily attracted by new things and are eager to explore the world.

    The adolescents(青少年) lack experience. {#blank#}3{#/blank#}This personality trait(特征)is called “sensation seeking”, which is shared by a lot of people and usually peaks during adolescence.

    Instead of being something to worry about, sensation seeking is actually necessary, since the process of learning usually goes hand in hand with taking risks. "Teenagers need to build experience so that they can do a better job in making the difficult and risky decisions in later life. 'Should I take this job? or ' {#blank#}4{#/blank#}' ”said Valerie Reyna, co –author of the study.

    “{#blank#}5{#/blank#}If they don't make a mistake in their teenage years, they will have no life experience when they turn 18 and step out of their parents' protection and into a world that's unknown to them. Kids need the freedom to test out boundaries while still in a safe environment,” wrote Ann Robinson, editor of The Guardian.

E. There's something scarier than taking a risk.

    We automatically assume that as adults, we're wiser than when we were children. However, actually we can learn a lot from our childhood self. For example, we can learn to develop optimism about the future. Do you remember how excited you used to be just before Christmas? {#blank#}1{#/blank#} Reintroduce that childlike wonder into our daily experiences.

    We can learn to dream big and imagine the impossible. How often have you heard a child say something like “One day, I'm going to be an astronaut”? Our adult minds immediately laugh at this idea and think about all the logical reasons as to why this might never happen. {#blank#}2{#/blank#}We minimize our chances of attaining what we dream about. It is okay to dream big just as our childhood self did.

    {#blank#}3{#/blank#} Our childhood self looked at possibilities and believed we could achieve them successfully. If we wanted to build a tree house, we'd go about thinking about how to make it happen instead of focusing on all the reasons it might not happen. In this way we can fill our life with possibilities rather than regrets.

    We can learn to be playful and silly sometimes, {#blank#}4{#/blank#} Children spend a large amount of time escaping from reality to mess about and have fun. Make time for your childhood self to come out and play. Run around the garden, wear a silly hat or spend time laughing. {#blank#}5{#/blank#}

A. Don't imagine things could go wrong.

B. We can learn to hold a “can do” attitude.

C. That feeling of great joy is hard to beat.

D. Most children tend to think in a positive way.

E. All of these activities can make us feel happy and alive.

F. We employ self-limiting beliefs without even realizing it.

G. All work and no play makes a person very dull and upset.

The most important thing to keep in mind when deciding to serve another is that service expects no rewards. When you expect something in return, and are not serving out of the goodness of your heart, others will notice. Sure they'll thank you. {#blank#}1{#/blank#}

When you give from your heart, the real power of service comes into play. Serving is a great opportunity to strengthen your trust and respect for another, and for them to do the same to you. Not only do you feel great about helping out, but you build your relationship with them, and they will feel more willing to help you in the future. {#blank#}2{#/blank#}

However, why is service so rarely seen these days? {#blank#}3{#/blank#} Sure, living in this day and age does not leave us much time, and the last thing people want to do is more work. I'm too busy, there's too much work, or I don't have the time, " may run through your head when you hear the word service, but the truth is the benefits are worth the sacrifice. Gandhi once said that, "The best way to find yourself is to lose yourself in the service of others. " {#blank#}4{#/blank#} Some ideas of places you can serve are volunteer centers, nursing homes, boys and girls clubs, and so on. You can serve people as long as you want to.

{#blank#}5{#/blank#} Although it does take some work, the benefits are more than worth the sacrifice. Not only do you feel better about making another's day a little less stressful, but you strengthen your relationship with them and they will be more willing to help you in the future.
