阅读表达。

     阅读下面的短文并回答文题,然后将答案写到相应的位置上(请注意问题后的词数要求)。

    On the 15th of each month, a classroom at Pointers Run Elementary School in Maryland, is packed

with volunteers. Students like Campbell Snoddy collect food that ____________ by students, parents

and teachers from each classroom. Then, the children check to make sure the food isn't too old. After

that, they sort it by category and put the cans and boxes into bags to be delivered to low-income senior

citizens in the community.

     "I wanted to teach my daughter about philanthropy (慈善)," says Julie Rosenthal, who started the

non-profit program six years ago. "And I wanted to teach other kids in the community, too."

     Children make their deliveries around the 15th of the month, when money from monthly Social

Security checks begins to run out and tough decisions between food and other needs have to be made.

     "I am on a fixed income and the food has helped me out considerably," says Linda Testerman, a food

receiver. "

     "It was really fun, it was great to make the senior citizens happy," says Campbell. "It was really cool."

Sofia Merkowitz, another Food on the 15th volunteer, agrees. "I really liked it because it made me feel

really good that people were so happy that they got food."

     Rosenthal says that is why she has children do more than fill a bag with donated food.

     "We want the children to have firsthand experience delivering the food to the people so that they can

get that feeling of really making a difference in somebody's life, a positive difference."    

     The program started with one school delivering 30 bags of groceries. It has grown each year, and now

involves 10 schools and several churches. Food on the 15th has delivered more than 12,000 bags so far. Rosenthal's goal is to expand Food on the 15th across the country and around the world.
