The largest outbreak of the deadly disease Ebola was caused by an infected bat biting a toddler, say a group of international researchers. The 17-strong team of European and African tropical disease researchers, ecologists and anthropologists have spent three weeks investigating the outbreak of the disease in Guinea, Liberia, Ivory Coast and Nigeria. The researchers captured the bats and other creatures near the village of Meliandoua in remote eastern Guinea, where the disease began in December 2013. The boy was bitten and passed the infection on to his mother and both died within a week. The disease was then spread far and wide by the people who came to the funeral. Most of the previous outbreaks have been caused by meat from dead infected animals collected by hunters who then sell it on. Fruit bats, however, are widely eaten in rural West Africa. The team, led by epidemiologist Herr Leendertz, a disease ecologist at the Robert Koch Institute in Berlin, are expected to publish their results in a major journal soon. Herr Leendertz's team believe that an infected straw-colored fruit bat brought the disease to Guinea. The mammals are known to travel long distances and usually settle in forests near cities. Herr Leendertz said, " The evidence is not 100 percent and we can only say that it is possible. They can travel far in one night. I don't think an individual bat or colony migrated all the way from Congo or Gabon to West Africa. These big colonies are connected. There is a possibility for the virus to mix between colonies. The bats share the same fruit. It is likely not to have even been one species of bat. The virus may jump from one species to another." If the bat theory is confirmed, the locals would try to destroy the colonies, which, Herr Leendertz says, would be an ecological disaster, because bats pollinate plants and kill insects. And bat hunts would also only increase human contact with potentially infected animals. What's the main idea of this passage? A) A toddler was bitten by a bat and died. B) The disease Ebola is incurable at present. C) An infected bat caused the outbreak of Ebola. D) The deadly disease Ebola broke out in Guinea.

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it's hard not to wonder if the disease that comes from foreign animals is homing in on human beings. "Most of the infections we think of as human infections started in other animals, " says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University. It's not just that we're going to where the animals are, we're also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen's pets, and she now thinks that keeping foreign pets is a bad idea. "I don't think it's fair to have them as pets when we have such a limited knowledge of them," says Isaksen. "Laws allowing these animals to be brought in from deep forest areas without stricter control need changing," says Peter Schantz. Monkey-pox may be Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug may be kind at first. But some strains may become harmful. Monkey-pox doesn't look a major infectious disease. But it is not impossible to pass the disease from person to person. Why did Isaksen advise people not to have foreign pets? A) They attack human beings. B) We need to study native animals. C) They can't live out of the rain forest. D) We do not know much about them yet.

Q: (2013*,C)One day,when I was working as a psychologist in England,an adolescent boy showed up in my office.It was David.He kept walking up and down restlessly,his face pale,and his hands shaking slightly.His head teacher had referred him to me."This boy has lost his family,"he wrote."He is understandably very sad and refuses to talk to others,and I'm very worried about him.Can you help?" I looked at David and showed him to a chair.How could I help him? There are problems psychology doesn't have the answer to,and which no words can describe.Sometimes the best thing one can do is to listen openly and sympathetically. The first two times we met,David didn't say a word.He sat there,only looking up to look at the children's drawings on the wall behind me.I suggested we play a game of chess.He nodded.After that he played chess with me every Wednesday afternoon--in complete silence and without looking at me.It's not easy to cheat in chess,but I admit I made sure David won once or twice. Usually,he arrived earlier than agreed,took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down.It seemed as if he enjoyed my company.But why did he never look at me? "Perhaps he simply needs someone to share his pain with,"I thought."Perhaps he senses that I respect his suffering."Some months later,when we were playing chess,he looked up at me suddenly. "It's your turn,"he said. After that day,David started talking.He got friends in school and joined a bicycle club.He wrote to me a few times,about his biking with some friends,and about his plan to get into university.Now he had really started to live his own life. Maybe I gave David something.But I also learned that one--without any words--can reach out to another person.All it takes is a hug,a shoulder to cry on,a friendly touch,and an ear that listens. What made David change? A) His teacher's help. B) The author's friendship. C) His exchange of letters with the author. D) The author's silent communication with him.
