The family had just moved. The young woman was feeling a little __1__. It was Mother’s Day – and 800 miles separated her from her parents.
She had called them that morning, and her mother had __2__ how colorful their backyard was __3__ spring had arrived. Later, she told her husband how she __4__ those lilacs (丁香花) in her parents’ yard. “I know where we can find some,” he said. “Get the __5__ and come on.” So off they went.
Some time later, they stopped at a hill and there were lilacs all round. The young woman rushed up to the nearest __6__ and buried her face in the flowers. Carefully, she __7__ some. Finally, they returned to their car for the __8__ home. The woman sat smiling, surrounded by her __9__.
When they were near home, she shouted “Stop,” got out quickly and __10__ to a nearby nursing home. She went to the end of the porch (门廊), where a(n) __11__ patient was sitting in her wheelchair, and put the flowers into her lap. The two __12__, bursting into laughter now and then. Later the young woman turned and ran back to her __13__. As the car pulled away, the woman in the wheelchair __14__ with a smile, and held the lilacs __15__.
“Mom,” the kids asked, “__16__ did you give her our flowers?”“It is Mother’s Day, and she seems so __17__while I have all of you. And anyone would be __18__ by flowers.”
This satisfied the kids, but not the husband. The next day he __19__ some young lilacs around their yard.
I was the husband. Now, every May, our yard is full of lilacs. Every Mother’s Day our kids __20__ purple lilacs. And every year I remember that smile of the lonely old woman. And that has become a lasting touching memory of my life.

One day, Miss Ellis gave her pupils a new kind of homework: homework on happiness. Her pupils would be “happiness    1   ”, and were to see what would happen when they tried to bring happiness to those around them. As part of their homework, all the students did really    2   , wonderful things, but what Carla Chalmers did left everyone    3   . Several days after the homework had been handed out, Carla turned up carrying a big bag.

“Here in this bag I have all the happiness I’ve collected so far,” she said    4   . On seeing this, everyone was filled with    5   , but Carla didn’t want to show anyone what was in the bag. Instead, she pulled out a small box and gave it to her teacher. When Miss Ellis had taken the box, Carla took a(n)    6    camera out of her own pocket and stood with it at the ready.

“Open it, Miss Ellis.”

The teacher slowly opened the box and looked inside. A big smile    7    on her face, and at that moment Carla took a photo, Carla’s photo came out of the camera immediately, and she    8     

it to Miss Ellis along with a sheet of paper. The teacher read the paper in silence, and when she, had finished, she gestured at the    9   .

“Oh, so it’s…”

“Yes!”    10    Carla, opening the bag. “It’s a great big pile of smiles!”

She opened the bag and photos of different    11    fell out.

The rest of the class tried to    12    how Carla had managed to create such a great big chain of happiness. All there in the box was a photo of a big smile. But everyone who had seen it felt happiness being transmitted（传送）to them, and in return, without    13   , every person    14    with a  smile of their own.

She managed to    15    understanding of the smile truth that every time you smile you are sending a gift to the world.
