（单词翻译）

 But polar bear courtship is never straightforward1. She likes to play hard-to-get. It's also a challenge for blizzardcam. 

 
She's testing his fitness, making sure he is a good catch. He skills on the slopes show room for improvement. And now, the female invents a new challenge--a climbing contest. Her huge claws act like crampons. Being lighter2 and nimbler, she has the advantage. Males can be twice as heavy reaching three quarters of a ton.
 
She's after a mate that's playful and energetic, one with strong genes3. But his chances are slipping away. She tested his performance and pushed him too far. Meanwhile, the mother with one cub4 is still sticking to higher ground. But deep snow is a real struggle for her little cub. She encourages him with reassuring5 calls.
