On the way to Tom's school，there was a small flower shop.Its owner was a kind old man.In this shop，there lived his five small pet puppies.One of the puppies was lame(瘸的).It always dragged its leg and followed the rest of the puppies.Tom often stood in front of this flower shop after school and watched the puppies.Of the five，Tom liked that little lame puppy most. One day，Tom saw a board hanging in front of the shop.It read “Puppies for Sale at $50”．Tom went straight into the shop.Pointing at the lame puppy，he asked the old man to sell it to him.Tom took a $5 note out of his pocket and gave it to the old man.“I only have $5 now and you keep it.I'll pay 50 cents a month for the rest，” Tom said.“But it is a puppy which will limp for the rest of its life.It will never be able to run with you or play with you in the park.Do you still want to buy it？” the old man asked in surprise.

Paragraph 2： Then，Tom approached the lame puppy with his twisted right leg. “I'm like this puppy too.Maybe it needs someone who can understand it.” Being touched，the old man picked up the lame puppy and gave it to Tom.“The puppy is lucky to have you as its owner.It will be a gift from me to you.Just take good care of it，” the old man said.Tom was overjoyed to get the little puppy as a gift and he thanked the old man sincerely.Then he took it in his arms and headed towards his house happily. 学科网（北京）股份有限公司 $$
