Dear Readers,

    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(消失) 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 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 will be 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 "hand up". 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 to help a child like Maria and her village.

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