One day something went wrong with a man’s bicycle chain(鏈條). The man could not repair it,
so he looked    16   for help. The only house nearby belonged to a woman who had
   17   there a few months earlier. The man knocked at the door, but the woman did not
answer. The door had clear glass in it, and the man    18   see that the woman was home. He
decided to knock again. Finally the woman came to the door. The man immediately explained his
   19  . “I can fix the chain,” the woman said. Later when the bike was    20   to go,
the man said, ‘Thanks. I hope I can help you some day.”“I never need help,” the woman said.
The following week the man was riding his bike    21  he noticed the woman walking
down the street. A strong wind suddenly lifted(拾起) her hat and sent it into the branches(枝) of
an old tree. The woman tried to get her hat with a stick, but she failed. She seemed    22   
because she clearly was not dressed for tree-climbing. The man hurried over, quickly climbed up
to the hat and    23   it into the woman’s waiting hands. When she put on her hat, she
   24   the man as he climbed back on his bike. ‘I think I told you I never need help,” the
woman said, “I’m glad you didn’t    25   me. Thanks.” Then they both smiled.

There was a little boy who got angry easily. His father gave him a bag of nails(釘子) and told him that every  16  he got angry, to drive a nail into the back wall. The first day the boy had 17  37 nails into the wall. Then he put fewer and fewer nails. He found it was　18  to be not angry than to drive those  19  into the wall. 　Finally the day came when the boy didn't get  20  at all. He told his father about it and the father suggested that the boy now pull out one nail for each day that he was able to be not angry. The days  21  and the young boy was finally able to tell his father that  22  nails were gone. The father took his son by the hand and led him to the  23　. He said, "You have done  24 , my son, but look at the holes in the wall. The wall will  25  be the same. When you say things 　26 , they leave a scar(傷疤) just like this one. You  27  put a knife in a man and draw it out. It won't matter  28  you say I'm sorry, the wound（傷口） is still there. A mental hurt is as bad as a physical one. Friends are a very rare jewel, indeed. They make you  29  and encourage you to succeed. They lend an ear, they share a word of praise, and they always　30　 to open their hearts to us.

Sheila bought a new lunch bag for school.

On the way to school, she looked inside. She hoped that a new lunch bag meant something new for lunch,   16   she found the same lunch as always---a sandwich.

When the lunch bell rang. Sheila found her bag and carried it to the dining hall. She opened it and   17   two pieces of fried chicken, several strawberries, and an egg.

“Wow!” Sheila said, “That’s what I call   18   !”

The next morning, Sheila opened her lunch bag and looked inside. Sure enough, she found another   19   . But when she opened the bag at lunchtime in the dining hall, she discovered a piece of pizza, an orange, and a cake.

“My lunch bag  20   be magic,” Sheila said.

“There’s no such thing as magic,” her friend Douglas  21   .

“There is,” Sheila said. “My mother   22   packs me a sandwich. But ever since I got this new lunch bag, the sandwich has changed into something I like.”

“Maybe your mother’s packing   23   things for a change.”

“No,” Sheila said. “I checked in the morning. The sandwich changes   24   .”

“You are not the   25   one with a magic lunch bag,” Beatrice said, turning around from the table behind her. “I have one, too. See? This is my magic bag.”

“Hey,” Sheila said. “My lunch bag really looks like yours.”

“Mine is magic,” said Beatrice. “Every day my dad  26   leftovers(剩飯), but at lunchtime I find a sandwich---my favorite!”

Sheila started   27   .

“What’s so funny?” Beatrice asked.

“That’s the sandwich my mother packs,” Sheila said. “We’ve been getting our lunch bags   28   up.”

Sheila and  29   shared their lunches every day after that. Sheila loved making new discoveries each time she opened her lunch bag. But her best discovery was magically finding a new   30   .
