MELBOURNE, Australia - A kangaroo frightened by a man walking his dog attacked the pair, throwing the pet underwater and hitting the owner in the stomach with its back legs. The Australian, Chris Rickard, was in stable condition Monday after the attack, which ended when the 49-year-old struck the kangaroo in the throat. Rickard said he was walking his blue dog, Rocky, on Sunday morning when they surprised a sleeping kangaroo in Arthur's Creek northeast of Melbourne. The dog chased the animal into a pond, when the kangaroo turned and knocked the pet underwater. When Rickard tried to pull his dog free, the kangaroo turned on him, attacking with its back legs and tearing a deep cut into his stomach and across his face. "I thought I might take action to drag the dog out from under his grasp, but I didn't expect him to actually attack me," Rickard, 49, told The Herald Sun newspaper. "It was a shock at the start because it was a kangaroo, about 5 feet high, they don't go around killing people." "I was stuck having to hold on to the dog with both hands because it was half drowned and I couldn't really see anything because the kangaroo just attacked me." He added, "All I could do was just keep pushing for the bank and he was trying to push me under the water, so at that point I struck him in the throat and that made him back off a little bit. "I don't think I'll ever be able to watch kangaroo programs quite the same as I used to -- it might bring back a couple of bad memories." Kangaroos rarely attack people but will fight if they feel threatened. Dogs often chase kangaroos, which have been known to lead the pets into water and defend themselves there. Rickard said he ended the attack by hitting the kangaroo in the throat adding Rocky was "half-drowned" when he pulled him from the water. As a result of the attack, _ . A) the dog was drowned dead B) the kangaroo was killed C) kangaroos should be under stricter protection D) Rickard was left a deep impression

Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution. What is the probable attitude of Stewart Brand toward bringing extinct species back to life? A) Supportive. B) Indifferent. C) Disapproving. D) Worried.

All young people dream of travelling the world. They are restless and very eager to see new sights. However, they have little idea how they would really do it if given the chance. Because their knowledge of geography is quite limited, they seldom know much about the places they wish to visit or how they would get there. Already hundreds of thousands of Chinese student tourists are visiting these places-Wuyi, Lhasa, Lijiang, Dali, Vientiane and Phnom Penh. Indeed, these students will soon be the most travelled generation in China's long history. The World Tourist Organization predicts that a quarter of a century from now the number of Chinese tourists going abroad will be twenty times what it is today. The largest percentage of these tourists will visit Southeast Asia. Not all Chinese who travel abroad will be tourists, however. More and more youths are deciding to volunteer their skills in this region; much like their peers in the Peace Corps and VSO. Critical thinking skills required include planning for a trip and solving problems after the trip has begun. The focus is on how to read an atlas to make travel plans and how to find ways of travelling. An atlas offers a wealth of information about geography and is one way to increase students' awareness of their global environment. Use of an atlas especially addresses the needs of students with different visual and spatial learning styles. One way to increase students' awareness of their global environment is for them to _ A) watch TV B) listen to radio news C) read an atlas D) plan a trip
