Article: Wood Buffalo National Park Wood Buffalo National Park is Canada's largest national park and one of the largest in the world. Established in 1922 to protect the last remaining herds of bison in northern Canada, it now protects an outstanding example of Canada's Northern Boreal Plains. The park was designated a World Heritage Site in 1983.

This discovery led to the establishment of Banff National Park, and marked the beginning of Canada's national park system. Spanning 6,641 meadows and rivers, Banff National Park is one of the world's premier destination spots.

Article: Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing.

Article: We are always told that TV is not good for us. If it is true, how come the TV-addicted kids of our young generation nowadays are much smarter than we are? In my family, the only persons who can work the TV remote control well are the children. Probably TV really educates us. For example, we can learn a very useful medical fact: _ . "The killer was..." (dies) But I suppose the biggest things that we learn from TV can be regarded as "Life Skills". Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are. I've even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from. To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn't worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women. TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you. Be warned, however, if your name card says "henchman" and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don't be anxious: TV also delivers useful information for bad guys. All cars are inflammable and have amazing shock absorbers that enable them to fly into the air and land without damage -- except police cars. TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
Answer: TV always shows news about famous people.
