【推荐3】Banff National Park, Canada*s first national park, is filled with wonderful scenery provided by the Canadian Rockies, valleys, forests and plentiful wildlife. The park is popular with people. Here is an overview of the most popular attractions in Banff National Park:
Johnston Canyon
The main activity at Johnston Canyon is to hike to the Lower Falls, Upper Falls and Ink Pots. Getting to the Upper Falls includes a 2. 7-kilometer hike that starts from behind the Johnston Canyon Resort. This path is considered one of the busiest in the Canadian Rockies, because hundreds of tourists like making the 45-minute hike every day.
Banff Gondola
Travelers want to make sure they have plenty of memory cards before they board Banff Gondola. That’s because the views from the four-passenger gondola cars (空中缆车)are fantastic . Once at the top, visitors can take the skywalk to get to a historic site and meteorological station (气象站).Banff Gondola is closed in winter. But there are also hiking paths to the top.
Banff Upper Hot Springs
Banff Upper Hot Springs is a perfect place to relax after a day on the hiking or ski ways. Visitors have been coming to this Banff attraction since the 1880s to bath in the therapeutic (治疗的)mineral waters, though First Nations were doing that long before the railroad opened up this part of Canada.

【推荐1】We often hear friends ask why they should read fiction. There is so much to learn from history, from what is going on at the frontiers of science, and from contemporary studies of human behavior. Why should they spend their scarce "free time" reading fiction, the purpose of which, at best, is only entertainment?
We are disappointed about such comments. Yes, we respond, we do find pleasure in reading fiction. But we also learn much about how to best live our lives in ways that can only be captured by fiction. We recognize that some novels are entertaining, but leave no lasting impression. What makes a novel more than entertainment?
Our answer is that we don't just read great books - they read us as well. The human condition is complex and contradictory, layered like an ice-cream dessert, with flavors mixed among the layers. A great novel reflects that complexity. We may read it several times, as we do with our favorites, and each time it is like finding an old friend and gaining new insights from that friend. We put it down with new understandings of the world around us and, most important, of ourselves.
Let's look at the novel Frankenstein, written in 1818 by Mary Shelley. Frankenstein is not the monster, but a young man seeking out the secrets of the universe. He collects body parts and charges it with life. When the dull yellow eyes open, however, Frankenstein, shocked by what he has done, abandons the creature, which ultimately kills Frankenstein's brother, his bride, and his best friend.
On one level, Frankenstein is entertaining - a good horror story, though a little dated. But Shelley writes more than just that. On a deeper level, her book forces us to ask whether humans reach too far to gain knowledge that is as forbidden as the fruit of the Garden of Eden. This theme, as old as the legend of Prometheus (普罗米修斯),dominates Frankenstein. Shelley, of course, knew nothing of genetic (遗传的)engineering that happens today. She was deeply troubled by what human beings might discover about themselves, and the effects of those discoveries on society. Our reading of great literature can also be enriched by understanding the author's personal interests and anxieties.
1. How does the author feel about fiction reading?A.It is a window to a whole new world. |

A.Because they deserve reading several times. |
B.Because they lead us to a rich and colorful life. |
C.Because they explore humans' complex reality. |
D.Because they improve the writer-reader relationship. |

【推荐3】The Calgary Public Library has some great resources to beat boredom and keep your children busy over the summer, whether at home or on the road.
During the school year children are busy with homework and required reading, so summer is a great time for them to relax and read what they choose. Not only is reading a pleasurable way to pass the time, it will also help children keep their skills up over the summer, so they are prepared to go back to school in the fall.
If you are taking a tip this summer, why not let the kids help out with the planning? Borrow a children’s atlas to choose your way together and check out some books about your destination before departure. The All about Provinces and Territories series is fill of interesting facts about each Canadian Province.
Going camping? How about taking along some scary, or not so scary, stories to tell around the campfire? Alvin Schwarz’s collections of Scary Tales to Tell in the Dark are sure to make your spine tingle and your teeth chatter. For something a little less horrible, try Velcome: a Very Scary Book, by Kevin O’Malley, which includes such horrors as a plate of mixed vegetables!
For long car rides, check out Car Games: 100 Games to Avoid “Are we there Yet?” It’s full of fun games and activities like cow football and Dude, where’s my orange car? —games that are sure to keep youngsters occupied on long journeys.
Remember to lead by example and pack a book in your own beach bag. If children see you reading, they will understand that books are an important and valuable part of summer and they will begin to copy your habits!
The staff at the Calgary Public Library are always happy to help find that perfect summer read, so stop by your nearest branch, call us at 260-2600, or visit our website at calgarypubliclibrary.com today.
