     Mario lives in Chicago, and he comes from Italy. He's married with two children, Sal and Made. His wife,

Connie, is also Italian, but she was born in the United States. Mario and Connie are big soccer (football) fans.

But when Mario came to the United States eight years ago, he didn't know that soccer was a popular sport

here. The only American sports that he heard a lot about were basketball, baseball and football. He was amazed

to learn that there were many soccer teams in the USA.

     One Sunday afternoon, he was taking a walk and discovered two teams playing soccer in a park. He

watched the game. Both teams had excellent players, and the game was exciting. When it was over, he talked

to some of the players. They were from Italy, Spain, and Latin America. One of the teams needed another

player, and they asked Mario to join them. He was happy to do so. Seven years later he's still playing in the

team, and he's one of their best players.

      His son Sal is also learning how to play soccer, and he goes to all of his dad's games. Mario practises

with him and shows him how to kick (踢) and pass the ball. He's only six years old, but he's fast and can

kick and pass well. His ability to play soccer is amazing (surprising). "Like father, like son," their friends said.

And Sal said, "I can't wait until I'm old enough to play in the team at my school."

     Last week Mario, Connie and their two kids drove all the way from Chicago to New Jersey to visit

Connie's cousins. She hadn't seen her cousins for five years, but the biggest reason for the trip was that her

youngest cousin was getting married. She didn't want to miss the big wedding (婚礼) and the family reunion.

Her cousins are also crazy about soccer. One night her cousin Lou was playing. It was the game of the season,

and the whole family went to the game. Mario and Connie cheered when Lou's team played well. The score

was 2 to 2 at half time. It was exciting. No one scored in the third quarter, and then with only 60 seconds left,

Lou scored, and his team won 3 to 2. After the game they went to have pizza and celebrate.
