     Handbags are one of the signature statements for every fashion conscious woman. Lauren Bush and Ellen

Gustafson have managed to turn this accessory into a necessity in the struggle to feed the world's hungry

children, one handbag at a time. "There's no other choice," Gustafson said. "We have to help them get into

school. That's the only choice we have."

     The pair met four years ago through their work with the United Nations. What they saw inspired the launch

of their collection FEED.

     Their first bag, a $ 60 reusable shopping one, provides a school meal for a child anywhere in the world for

an entire a year, "World hunger seems so far away and so overwhelming (势不可挡的) for most people," Bush

said."So to know exactly what you're doing is great."

     FEED now has a dozen styles in some of New York's most popular stores. Prices range from $ 15 to $ 195.

The cost varies because each bag provides help in a different way and says so right on the back.

     When the earthquake hit Haiti, FEED designed the "FEED Haiti 50" bag. It provides 50 school lunches for

children there. "That meal that a child gets in school is almost certainly the only proper meal that they get

everyday," said Marcus Prior, UN spokesperson in Haiti.

     Every year hunger and malnutrition kill more people in developing nations than AIDS, malaria, and

tuberculosis combined. That's 3 million children who never make it to their fifth birthday. 300 million other

children go to bed hungry every night.

     Since 2007, FEED has donated $ 5. 5 million to the UN World Food Program. "Hunger is a very terrible

feeling, it's a very terrible way to die," Gustafson said. "To know that just through selling a product we can

help them get the most essential to human life-food to thrive-is very powerful."

1. What's the purpose of the launch of FEED?

A. To help the hungry children.

B. To recycle the waste handbags.

C. To promote the sales of handbags.

D. To make all the children receive a good education.

2. Which of the following is True about the FEED handbag?

A. It has only one style.

B. Its price stays the same.

C. It is popular with lots of women.

D. The help it offers is marked on the back.

3. From what Gustafson said in the last paragraph, we can infer that ____.

A. she was afraid of dying from hunger

B. she was proud of what they did

C. she had ever suffered hunger

D. she called on people to help the hungry

4. The underlined word "malnutrition" in the sixth paragraph probably means ____.

A. poor nutrition

B. depression

C. balanced diet

D. super nutrition
