　　Though chopsticks are used in many Asian countries. they have their beginnings in China. Chinese history says that the Chinese had chopsticks as far as the Xia Dynasty (朝代) (about 4, 000 years ago) In the Spring and Autumn period (时期)copper and iron chopsticks appeared . With the Han Dynasty lacquered (上漆)chopsticks came ,followed by gold and silver chopsticks still later .Today we have chopsticks made of plastics .The most expensive are made of part of tusks of elephants and hard green stone.

　　Chopsticks tell Chinese tradition in their way .In ancient (古代的)times the rich used hard green stone or gold chopsticks to show their wealth (富有).In history many kings used silver chopsticks to take their food to see if it was poisonous (有毒的).It was said that if it was ,the silver chopsticks would turn colour .Chopsticks are traditionally given to a daughter when she marries to show that they should have a son very soon ,for “Chopsticks”in Chinese is pronounced like “quick a son”!

　　Many westerners , businessmen ,tourists put aside (一边)their knives and forks in favour (喜爱) of chopsticks in China

　　Chopsticks appeared in the old Chinese story: an old man teaches his sons a lesson by showing how he could easily break a single chopstick but not a number of them .In China chopsticks are connected with good luck .So on the country's New Year's Eve many families will lay out new chopsticks at dinners as a way of making requests for luck.

Dear Reader,

Imagine an 11-year old girl whose days are often spent washing clothes, looking after a baby, working hard in the field.

Imagine a little girl who knows there will not be enough food for dinner, who can’t fill her stomach with water because it’s polluted, and who has watched life slip away from her father, little brother and sister because the family is too poor to see a doctor.

Is it hard to believe? For Maria Pastora, these are the real life.

Maria would gladly walk miles to school, but her mother, now alone, needs her badly at home. If Maria grows up without any schooling, what will be her future?

But for just 52 pennies a day, you can sponsor a child like Maria. Through “Save the Children”, you can help Maria’s mother get the tools and ways she needs to turn their poor food into a good dinner and the money she needs to buy clothes and school things for Maria.

To help Maria most, your money is put together with that of other sponsors, so hard-working people can help themselves. Build a school, a hospital…bring in clean water. This is what “Save the Children” has been about since 1932.

For you there are many rewards. Have the chance to write to or hear from your sponsored child. Receive photos or progress reports. Know you are reaching out to another person. Not with a handout(施舍物), but a “handup”. That’s how “Save the Children” works. But without you, it can’t work. Please take a moment now to fill in and post the form below to help a child like Maria and her village.

It can make such a difference in her life and yours.
