Last month, my good friend Mark got an expensive watch as his birthday present. He showed to everyone in my class proud. I really envied him and every day I ask my mum to buy me an expensive present. However, to my disappointment, I only got a second-hand bike at that special day. So one day while I was riding my “dear” bike back home from school, I passed the shop that my mum worked. I saw a familiar figure kneeling down in the front of it cleaned the outside steps of the shop. It was my mum! She worked so harder to raise me! Tear in my eyes, I got off the bike and worked together with her.

    The UN has recognized the contributions of volunteers on Dec. 5, International Volunteer Day. Here, the four things are offered to consider before taking the leap into overseas volunteering.

Choose your organization carefully

1. volunteering may be a fundraising mechanism(筹资机制) for a development project. For others, volunteering is fundamental to their programs, and those serving take on professional roles in longer-term development.

2.

Volunteers want to help and make a difference, but most know this isn’t a purely selfless act. You will learn new skills, broaden your horizons and come to better understand yourself and the world. 3. Reflect on your motivations. You want to help reduce global poverty or protect the natural world, but what else? Have you always wanted to travel, but not as a tourist? Work with kids? When you understand your motivations, you’ll be in a better position to choose the option that is right for you.

Work alongside the local community

Often times, travelers volunteer in isolation(隔离) from the local community in which they are working in. 4. This enables you to ensure you are committing to a project that promotes long term and sustainable change.

A volunteer trip is just the beginning

5. Further ignite(点燃) the global change maker in you by taking your experience one step further when you return home. Spread the message of your transformative experience to others, helping to spark the change within them.

A. And that’s all OK.

B. Know why you’re going.

C. Don’t assume you know it all.

D. Communities always welcome volunteers.

E. Volunteer travel is a life-changing experience.

F. Some organizations require you to pay your own way, and often include a fee.

G. Make sure to travel with organizations that have strong partnerships with local communities.

    What’s small, buzzes here and there and visits flowers? If you said bees or hummingbirds, you got it. You wouldn’t be the first if you mixed the two up. Now a group of researchers even say we should embrace our history of considering the two together in the same group. The way scientists study bees could help them study hummingbird behavior, too.

Scientists first compared the two back in the 1970s when studying how animals search for food. The idea is that animals use a kind of math to make choices in order to minimize the work it takes to earn maximum rewards. Researchers at the time focused on movement rules, like the order in which they visited flowers, and where flowers were located relative to others. It was “almost like an algorithm(算法)” for efficient searching, said David Pritchard, a biologist at the University of St. Andrews in Scotland. Hummingbirds and bees had similar solutions.

As the field of animal cognition(认知) appeared, hummingbird and bee research parted. Neuroscientists and behavioral ecologists developed ways to study bee behavior in naturalistic settings. Hummingbird researchers compared hummingbirds to other birds and borrowed methods from psychology to study their ability to learn in the lab. To be fair, hummingbirds and bees differ. For example, hummingbirds have more advanced eyes and brains than bees. Honeybees and bumblebees are social; hummingbirds typically aren’t.

But however they perceive(感知) or process information, they both experience similar information, Dr. Pritchard said. In day-to-day searching for food, for example, hummingbirds may rely on more of a bee’s-eye view than a bird’s-eye view. Like other birds, they rely on landmarks, distances and directions to make maps when travelling long distances, but they don’t use these cues to find flowers. Move a flower just an inch or so away from where a hummingbird thought it was and it will hover over the flower’s original location. Dr. Pritchard is investigating if, like bees, hummingbirds engage in view matching — hovering, scanning snapshots of a place to its memory and using those as references later.
