Problem: (CNN) -- World No.2 Novak Djokovic extended his season's winning streak to 26-0 on Saturday, as he reached the Serbian Open clay court final after his semifinal opponent Janko Tipsarevic withdrew with a thigh injury.

Writing on his Facebook page, Djokovic said: "Janko had to pull out from tonight's semi-final match because of a muscle injury. I sincerely hope he will manage to recover for the rest of the clay court season. I will try to get the title back where it belongs and that is Serbia."

The 23-year-old will be chasing his fifth title of season on Sunday.

Standing in his way is the Spaniard Feliciano Lopez who beat the Italian Filippo Volandri 7-6 (7-3) 6-2 in his semifinal.

The reigning Australian Open champion will take an unblemished 3-0 career lead into the clash with the left-handed Lopez, who is currently ranked No.37 in the world.

The Spaniard is looking forward to the challenge.

"I've already won four matches this week. My confidence is really high at the moment and I feel great to play against Novak. I know it's going to be tough; he's been the best player this year. It will be a great experience," Lopez said, AFP reported.

Meanwhile, at the Estoril Open in Portugal, Argentina's Juan Martin del Potro defeated Pablo Cuevas 6-2 7-6 (8-6) in Saturday's semifinal.

Del Potro took one hour and 49 minutes to overcome the Uruguayan breaking Cuevas's serve in the first game helping him establish an 4-2 lead when rain intervened.

Q: After two weeks, Ling Qinghao finally sent a message to his wife in their hometown in Anhui, and told her her he was safe. Ling, 44, was a Chinese construction worker who went to Libya. The recent problems in Libya have left the country in disorder. Several Chinese were injured last month. Ling was one of the thousands of Chinese evacuees from Libya. The evacuee's first stop was Greece. They are staying there in a five-star hotel that the Chinese government paid for. According to the Foreign Ministry, by March 2, China has evacuated a total of 35,860 Chinese from Libya. Among them, 20745 have already returned to China.

Problem: There was once a young bear who lived in a small cave in the woods. His cave was comfy, warm, and dark, and had a bit of a yard in front of it. The bear lived with his mother and father, and spent his days walking around and his nights curled up asleep. He liked to look for berries to eat. His favorite berries were blueberries, but he would eat any berries he found: strawberries, raspberries, cherries, anything.

There was a river near the bear's cave, and he loved to sit on the bank and look at the fish and frogs, and at his own reflection in the water. One sunny afternoon, when he was looking into the river, he saw a family of ducks swimming by. He got up and followed them. They swam along in the river, and he walked along the bank. They traveled like this until they reached a small clearing in the forest. The bear stopped and looked around, and saw that the clearing was completely filled with blueberries -- more than he had ever seen!

The young bear ate his fill of blueberries, then took home as many as he could carry in his paws. He went to bed happy. It was a wonderful day.
