On a cold snowy evening, a rich lady was standing by the road. She looked very worried because her 1 broke down and she had already waited for an hour. Just then a poor man named Robert came. He was on his way back (to the) 2 from the interview* of a company.
The lady thought "Is the man going to 3 me? He looks so cold and hungry." 4 to her surprise, he stopped and said with a smile. "Can I help you, Madam?"
After forty 5, the car was at last fixed* by Robert. The lady wanted to pay him.
"No, that's 6, Madam, "he said. "I was just helping someone in need. If you really want to pay me back, I 7 whenever you see someone in need, you should give him a hand."
A few minutes later, the lady saw a shabby* house by the road. She remembered Robert's words, so she stopped.
The hostess warmly asked her 8. And the Lady could see that it was a 9 family and that they needed help. When the hostess was making tea in the kitchen, the lady 10 500 dollars on a table and went away quietly.
Robert came home later than before, thinking how 11 their life was. His wife was pregnant and the baby would be born the next month but there was not enough money. His wife went up to him, gave him a kiss, just like what she 12 did. Robert hugged his wife, "Honey, I am so sorry. I haven't 13 the interview yet. Tomorrow I will try another company." His wife said 14, "Don't worry, dear!Everything's going to be all right. A stranger helped 15 out."
Let's always be ready to help others because helping others is helping ourselves.
