阅读理解。 Every day, putting food on the table is a challenge for many Americans. They worry that they won't be able to feed their families. The slowing economy, increasing unemployment and rising food prices are contributing to the growing number of people who need help. The nation's food banks are rising to the challenge. It is estimated that they are currently serving 38% more people than they were a year ago. 'In Minnesota, the jobless rate is the highest it's been in many years,' says Tricia Theurer of Second Harvest Heartland, a hunger-relief organization in Minnesota.'More and more people are needing to ask for help for emergency food, many for the first time, due to economic situations.' Second Harvest Heartland provides about 41.5 million pounds of food annually to 170,000 people in 59 counties in Minnesota and Western Wisconsin. The group is part of Feeding America, the nation's food-bank network. Its members include 205 food banks serving every county in the United States. Hunger affects children, adults and seniors. It affects those who live in the city, in the suburbs and in rural areas. It affects those who do not have jobs and the working poor. The working poor are the fastest growing group of food-bank clients. They are employed, but simply do not have enough income to buy enough food to feed their families. Kids and adults can participate together in the fight to end hunger. The money you donate to the food bank may seem like too small an amount to make a difference, but a simple $1 donation can be used to distribute more than $9 worth of food. 'Kids can be very creative in coming up with ideas of how to help others,' says Theurer.'Some kids run lemonade stands, others have asked guests to contribute food or money to Second Harvest instead of presents.' 1.
