6 . Banff National Park is home to an amazing wildlife population. But the busy Trans Canada Highway that cuts through the park is a hazard to the lovely animals. To address the problem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”

There is some criticism (批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”

Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.

Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.

I’m not Chinese, but I love Chinese New Year. There are many fun New Year     1     (celebrate), but nothing quite matches the excitement of the lion dance which can wake up the spirit     2     (complete).

The sound of the drums,       3     you can feel throughout your entire body, is quite inspiring. The two performers are very flexible. But it is actually very difficult as the lion head is very heavy and being the     4     (low)part of the lion is tiring as he has to bend his back and also carry     5     person in front sometimes. The lion head is made with paper over a bamboo frame,       6     (cover)in gauze (纱布), and decorated with beautifully-colored materials.

The lion dance     7     (believe)to have first appeared in the Qianlong Emperor's dream during his Southern tour, and he ordered an animal     8     (make)in the likeness of his description and used in festivals from then on.

I love all about the lion dance. The other day, I saw a film about a left-behind teenager who insisted on pursuing his dreams despite difficulties and     9     (succeed)in lion dance. As Master Xu translates: “Heaven has made us talents; we’re not made     10     vain.”
