Sundays,I walk to the supermarket. Mother hands me the grocery list and puts money in my pocket,hoping it will be enough. She's had a hard day,and have had a hard week. Nothing out of the ordinary happens when I get to the store. I grab the bread,some milk,and other things on the list. As I turn to head out,I see ? beautiful dress in the window. I turn away,bitter that I could never own such a dress.
Outside,I cannot stop thinking about that pretty dress. It' s not fair that I can never have what I want. I work so hard to help my family and yet I get nothing in return,just another list to do. In my anger,I fail to realize the apples are rolling across the road. Suddenly,I see a pair of hands,offering me an apple. Looking up,I see the tanned (晒黑的) face of this stranger. ?is clothes mismatched,bo?owed or stolen. But his eyes are soft and kind.
“Thanks ,” I say. No other Rords are spoken as he continues to help me. I teirhim “thank you”
one more time and am on my way because I have many other things to finish. Suddenly,he says, “Have a good day,ma ,am." And then he gives me the biggest smile I have ever seen. Right then,he looks years younger 一 and I feel a fool.
Look at me,feeling sorry for myself because I don’ t get what I want! Do I not think others are in the same boat,or worse? There are worse things than not having a beautiful dr?ss.

A
★★★★☆
The goat (畜棚) at a Putnam County market in Greencastle,Indiana,will soon be full of,well,goats. But right now it’s full of tables (堆积) with clothes,books and housewares.
At the tables are families,lots of them. Some waited in line for more than an hour to have the right to get the larger things,like furniture. Carrie Ardito was first in that line and ran to the back to get a clothes dryer.
Yeah,I wasn’t expecting one. But I saw it,and it was wonderful!w Ardito says. “It s something I can't afford on my own."
With so many eager new owners,it's hard to believe that most of these things were voluntarily left behind by students at DePauw University, about a mile up the road. For the last six years,the school of about 2 ,200 has developed a yearly program,encouraging students as they move out of the dorms each year to give things away — not throw them away.
Ed Sparks is helping his wife search on the tables.
She was mainly after a bed — a couch-bed, whatever you want to call it — for the little one,” Sparks says.
The little one is their daughter,Madlynn,who was smiling and playing with a large,yellow foam hand from some past DePauw sporting event.
It means a lot,Sparks says. ^Nqw she has something a little bit better than what she's got right now."
Allen Denhart,who was moving his daughter Emily out after her first year,sardTTe movea his kids out of dorm rooms before but was doing it differently this year because of the continual reminders to give away.
Yeah,normally I would have just taken it to the garbage can if I didn’ t know,” he says. “Like that big piece of carpet there,it will probably save somebody $50 or $100 if they need a piece of carpet for next year."
only about a dozen families benefited. This year it's more than 100.
1. Which word can be used to describe Ardito,s feelings?
A. Afraid. B. Proud.
C. Satisfied. D. Worried.
2. Who started the program?
A. A Putnam County market.
B. Some college students.
C. Some local farmers.
D. DePauw University.
3. What did Madlynn need according to Sparks?
A. A small toy.
B. A couch-bed.
C. A bigger dinner table.
D. A sporting event ticket.
4. When Denhart moved his kids out of dorms
before,
A. he threw unwanted things away
B. he usually gave things away
C. he tried to bring everything home
D. he sold used carpets at low prices
5. What can we learn about the program?
A. It helps local families save some money.
B. It has become less popular over the years.
C. It improves communication among farmers.
D. It is a chance for students to know about animals.
