Dear readers,

     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 (被污染), 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. She would gladly walk miles to school, but her

mother needs her badly (非常) at home. What will her future be?

     Is it hard to believe?

     For Maria Pestora, these are the real life. But for just 52 pennies a day, you can sponsor (资助) 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 get 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. Building a school, a hospital,

or bringing in clean water is what "Save the Children" has been about since 1932. For you there are many

rewards. You have the chance to write to or hear from your sponsored child, to receive photos or progress

reports, to know you are reaching out to another person, not with a handout (救济品), 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 below to help a child like Maria.

     It can make a difference in her life and yours.

                                                                                                                                      For the children

                                                                                                                                      David Li Guyer
