I'm taking a test and have to guess the right answer to the question after the article. Article: This hotel in the trees is famous in the world. Peop1e who know very little about Kenya, know of Treetops. When King George VI died, Princess Elizabeth was staying on the Treetops, and when she came down from there, "She succeeded him as the queen of the country". This hotel in the middle of the forest shows the pleasure of Africa. When you visit it, you will be sent into the heart of the forest by hotel buses, and then a guide, with a gun to protect you against big game, will go with you to the Treetops. Before and after dinner, for the whole night if you wish, you can sit on the corridor , watching animals come to the water pool. The earliest hotel Treetops was built round a large tree on the opposite side of the water, but that was destroyed by fire and the new hotel Treetops, which is built round several trees, is much bigger. The dining room at Treetops is small, and the waiters cannot walk round to serve guests, a clever "railway service" has been invented. Guests take their food as it passes slowly in front of them, along a line in the center of the table. There are many animals around the Treetops. When you visit them, you can see: ---Animals and their babies are waiting to greet the guests. ---Animals, enjoying the Treetops pool in the daylight. ---A long bodied, long ring tailed very active cat-like animal is a special one coming out at night. He hunts and eats anything he can overpower and is very destructive. He lives in the trees at Treetops .He comes for his food every evening. Do not get too near to him, as his teeth and claws can do you harm. These animals can be trained and become lovely pets. ---Some other animals who have a thick coating of fur to keep them warm in the cold forest nights. ---Many buffaloes coming to the Treetops for water and salt during the day or night.

I'm taking a test and have to guess the right answer to the question after the article. Article: So you think you know your dog. But how well does your dog know you? She probably recognizes you when she sees you. But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference. Dogs are very mindful of sound. When dog owners shout or speak in a strong, unkind voice, dogs often act ashamed and quietly move away from the area. Recently, researchers found that dogs can look at our faces, and tell the difference between a smile and a frown . The animals were able to recognize a look of praise from one of blame. Researchers at the University of Veterinary Medicine, Vienna performed a series of experiments. They taught dogs to recognize facial expressions. They showed the dogs two pictures of either the upper or lower half of a person's face. On one picture, the person looked happy. The other appeared angry. The dogs were then shown images of the eyes or mouths of people they had never seen before. They were also shown the left half of the faces used in training. Corsin Muller led the study. "We were really speaking, do they realize that smiling eyes have the same meaning as a smiling mouth, or angry eyes have the same meaning as an angry mouth? And it turned out that they really did perform very well in these research experiments." Once the dogs learned to recognize which image was happy or angry, they could easily find the same expressions in pictures of any face. Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions--for example, whether a frown shows that someone is angry. In the experiments, researchers found the dogs were slower to link a reward, or prize, with recognition of the angry face. This suggested that dogs had an idea people with angry faces were best avoided. Question: A dog is able to recognize one's _ . Options: A: praise B: blame C: anger D: all of the above

Over millions of years, as climates change and mountains rise, new dry and wet areas appear. But within the last hundred years deserts have been increasing after frightful speed. This is partly because of natural changes, but most responsible for creating deserts are men. Man can make deserts, but they can also prevent them from getting bigger. Algeria is planning a green belt of trees along the edge of the Sahara Desert to stop the sand. In China, too, _ are being built in the northwest to keep the desert from growing. But desert still threaten the world. Experts believe that land that is on the way to becoming deserts equals the size of Australia, Russia and US put together.

I'm taking a test and have to guess the right answer to the question after the article. Article: They are the sort of friends who are so close they trust each other with their lives. If one falls, the other is there to catch him. They are Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident, and Corbett, an experienced rock climber. Together, they climbed up Half Dome, the famous 2,000-foot rock in the Yosemite National Park, through one of the most difficult routes . During the climb, Corbett took the lead, hit in the metal spikes that guided the ropes and climbed up. Then, after Wellman pulled himself up the rope, Corbett went down to remove the spikes and climbed up again. This process was repeated time and again, inch by inch, for 13 days. Wellman's job was not easy either. He got himself up the rope through upper body strength alone. In all, Wellman figured that he had done 5,000 pull-ups up the rope on the climb. However, when the two men first met, they never talked about climbing. "He knew that was how I got injured." Wellman said. Until one day Wellman decided that he wanted to climb again and they started training. Their climb of Half Dome was not all smooth. At one point, pieces of rock gave way, and Corbett dropped down quickly. Wellman locked their rope in place, stopping the fall at 20 feet. His quick action probably saved his friend's life. "Your partner can save your life -- you can save your partner's life," Wellman said as the pair received congratulations from friends. "There are real close ties." Question: What do we know about Wellman? Options: A: He climbed Half Dome by himself. B: He was disabled in a traffic accident. C: He stopped rock-climbing for some time. D: He was saved by Corbett during the climb.
