Li Na calm and collected for Australian Open final  

李娜"脱胎换骨"因心态转变 "王者归来"静对决赛

“脱胎换骨”的李娜如今变得几乎不可战胜。24日的澳网女单半决赛，面对俄罗斯美女莎拉波娃，中国一姐仅用时93分钟，就以两个6比2、五破对手发球局的表现赢得胜利，职业生涯第三次杀入大满贯决赛。

Melbourne (CNS) -- Chinese tennis player Li Na said on Thursday that she will "keep cool" at the upcoming final of the Australian Open.

Li said of her easy defeat of Sharapova in the semifinal: "I controlled my emotions well in that match."

When asked about the change in attitude, Li smiled and said, "I have become more mature, and I have learned how to control my emotions."

An excellent player should also be a good actor, she added.

Pressed about the upcoming final, Li said that only one person can be the winner, and "I will face it with an active mind and enjoy the happiness of playing tennis."

It's the second time for the French Open winner to reach the final in Australia.
