Lucy is a four-year-old girl. Her father likes running very much. He often exercises every morning. Lucy asked her father why he did that every day. “Oh, my dear! It can help me keep healthy.” Her father answered. “That’s good! May I exercise with you in the morning?” Lucy asked. “I don’t think it’s a good idea because you can’t run fast and it’s cold now. But you can do it when spring comes.” Lucy was not happy. At the beginning of the following（接下来的）spring she was so happy to know she could run with her father. Her mother took her to buy sports shoes, a sports hat, a sports bag and other sports things. On the first day, Lucy got up early and exercised with her father. She was very happy.

Cricket (板球) is Australia’s most popular summer sport. It is so popular that many people say summer does not start until Australians play their first cricket game of the season.

It is known as the “Summer of Cricket”. Most Australians will watch games on TV, listen to the commentary (评论) on the radio or play games themselves.

Many even go to the stadium and watch games live. They dress in green and gold and paint their faces to support the Australian team.

Two teams of 11 people play against each other. They take turns hitting a leather (皮制的) ball with a wooden bat. The batsmen (击球手) hit the ball to score runs (攻方得分）. The team that scores the most runs wins.

Some of Australia's biggest celebrities are cricket players. The sport is extremely popular in other countries like the UK, India, South Africa and Sri Lanka.

Men, women, boys and girls watch cricket. Traditionally it is a sport for men, but recently women's cricket has become popular and there are now female professional cricketers too.

“The first day of the summer of cricket is one of the best days of the year.” cricket player and fan Sean Prior said.

“When I'm at work I always have the radio on listening to the game. Cricket is a big part of my life.”

There are more and more cricket competitions starting in China. China has its own men’s and women's cricket teams that are gradually getting better.
