If you had billions of dollars, would you donate almost all of it to charity? Well, that's what Mark Zuckerburg, CEO and founder of Facebook, just said he would do.
    Zuckerburg and his wife Priscilla Chan promised to give 90% of their Facebook shares to society. Right now that is about $45 billion, and they plan to donate the money to things like science and education.
    Many billionaires have done similar things. Bill Gates, creator of Microsoft, made The Giving Pledge, an activity in which billionaires promise donate more than half of their wealth to charities. This started in 2010, and now 139 people from 15 countries joined it.
    But giving back and helping others isn't just for big billionaires. People like Zuckerberg, and Gates may have more to give, but people with less are doing it, too.
    Especially around the holidays, people want to do their part and give back to people who are less lucky than them. Schools may have food collections where people bring a few food items, and together they can make a big donation to places like homeless people's homes.
    People also host special events like concerts of runs to be creative while raising money. Regular people donate whatever they can to US charities like the United Way and the American Red Cross.
    Then these charities are able to help US communities in different ways like education, health and improving the lives of the poor. These individual donations come together to make a big difference.

I'm Carl. I love soccer and I play soccer with my friends every week. In one game I break my leg (摔断了腿). My friends take me to the hospital. 

The doctor says I need an operation (手术). The doctor is very nice. He helps me to relax. Then I go into the operating room. Another doctor is there. She is very nice, too. She gives me anaesthetic (麻醉). Then I fall asleep (睡着). 

About 4 hours later, I find I'm on a white bed. My parents and my friends look at me. The doctor says I must stay in bed for six weeks and that I can't do any sports in the next six weeks. It is difficult for me, but I must listen to the doctor because I want to be healthy and play soccer again. 

My good friend Carlos invited me to his birthday party. He moved to Canada from Mexico when he was a baby, but his parents tried to follow some of the Mexican traditions. At his party, I saw my first pinata (彩盒). It looked like an animal and was full of candies. People put it on the ceiling (天花板). Carlos hit (打) the pinata until it broke. All the candies fell on the floor, and we had a great time eating candies. Everyone shared. It was fun! 

Carlos's birthday party got me thinking about how kids in other places celebrate birthdays. 

Do you know that in Vietnam, everyone's birthday is on the same day? Kids do not celebrate on birthdays. Instead, on New Year's Day, all the kids celebrate their birthdays. Parents give kids red envelopes (信封) with lucky money in them. What a great way to celebrate birthdays! 

In South Africa, kids do not celebrate every birthday. However, on their 21st birthday, their parents make a key. It can be made of paper or wood. Parents give their child this key. It is a sign from the parents that the child can now "unlock the door to their future life". 

In Japan, children get a new set of clothes on their birthdays. While in Italy, adults (成年人) pull children's ears—one pull for each year. In Denmark, a flag flies outside the window of a house where a child is having a birthday. When the child is asleep, adults put presents all around the child's bed.
