A little boy was visiting his grandparents on their farm. He was given a slingshot(弹弓）to   21 in the woods. He practiced and practiced but could never   22  the target. Becoming somewhat   23 , he headed back for dinner.
As he was returning, he saw Grandma’s   24 duck. Without thinking, he shot his slingshot, hit the duck right   25 the head and killed it. He was shocked and sad. Quickly, he   26 the dead duck in the wood pile, only to see his   27 watching. Sally had seen it all, but she said nothing.
After   28 that day, Grandma said, “Sally, you wash the dishes.” But Sally said, “Grandma, Johnny told me that he wanted to   29 in the kitchen today, didn't you, Johnny?” And then she   30 to him, “Remember, the duck?” Then Johnny did the dishes.
Later, Grandpa asked if the children wanted to __31__ fishing, and Grandma said, “I’m sorry but I __32__ Sally to help me make supper.” But Sally smiled and said, “Well, that’s all right. Johnny told me he wanted to __33__.” And she whispered again, “Remember, the   34  ?” So Sally went fishing and Johnny   35 at home.
After several days, Johnny finally couldn't   36 it any longer. He went to Grandma and   37 that he had killed her pet duck and asked for her   38 .
Hearing this, Grandma knelt down, gave him a hug, and said, “Sweetheart, I know. You see, I was standing at the   39 and saw the whole thing from the house. And because I   40 you, I forgive you, but I was just wondering how long you would let Sally make you her slave.”

A passenger told an air hostess that he needed a cup of water to take his medicine when the plane just took off. She told him that she would   21 the water in ten minutes.
Thirty minutes later, when the passenger’s ring for  22  sounded, the air hostess realized it at once. She was kept so  23  that she forget to deliver him the  24  . As a result, the passenger was  25  to take his medicine. She hurried over to him  26  a cup of water, but to her surprise he  27  it.
In the following hours on the  28  , each time the air hostess passed by the  29  , she would ask him with a  30  whether he needed help or not. But the passenger  31  paid attention to her words.
When he was going to get  32  the plane, the passenger asked the air hostess to  33  him the passenger’s booklet(意见簿). She was very 34  . She knew that he would write down  35  words, which might result in the loss of her job.  36  with a smile she handed it to him.
Off the plane, she  37  the booklet and cracked a smile,  38  the passenger put it, “On the flight, you asked me whether I needed help or not for twelve times  39  . How can I refuse your twelve sincere smiles?”
That’s  40  ! Who can refuse twelve sincere smiles from a person?   

A camp built by students and volunteers spreads over Southern Methodist University（SMU）. The affordable  21  are designed to be used by the poor as well as survivors of war and natural disasters.

“By the time 2020, there’s going to be about 1.7 billion people living in slums（贫民窟） so we would like to  22  change,” says Stephanie Hunt, co-founder of the Hunt Institute for Engineering and Humanities at SMU. The institute, which  23  build the village on SMU’s campus, was established to solve problem of the poor in the United States and around the world through engineering, and the free  24 .

The goal is not just to  25  lives, but to change the victims’ lives. The Institute hopes some entrepreneurs（企业家） might program and  26  some money with these ideas. One of the structures in the SMU village was built with bricks made  27  from recycled plastic bags.

They’re  28  together with heavy wires. Harvey Lacey, father of two college-aged sons, including one here at SUM, heard about this project and  29  his invention. It’s a heavy-duty, hand-crank compactor（手动压缩机）that anybody can use to form the big bricks he calls Ubuntu Blox.

“The advantages are that these  30  weigh less than two pounds. They’re very, very  31  These things can go for many generations of housing, ”says Lacey, who is  32  the design. Anybody can follow his online plans to  33  the compactor that turns plastic bags into bricks.

On this warm day, it’s  34  inside the Ubuntu Blox hut, thanks  35  to the thick plastic insulation（绝缘）. Kenyan  36  Ronald Omyonga, visiting the global village before returning to his native Africa, says his country is full of these recyclable bags. With Lacey’s design, he says that litter could be transformed into  37  housing. He dreams of other  38  too.

“Look at the Harvey Lacey hut, as a means of creating  39  ,”says Omyonga.“Leaning the environment, and turning  40  into something that can form houses, not just for the poor.”
