Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades. Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct.The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity , overfishing and pollution. The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation.This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel. "Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project."In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said."Their projects will last initially for two years.We provide them with a whole host of tools to carry out their projects including funding and intensive training." She added. Coral reefs are the planet's most diverse marine ecosystem , known as the rainforests of the oceans.Despite taking up under 0.2% of the ocean floor, they provide food and shelter for almost a third of all sea life.If we lose the ecosystems, we lose not only the biodiversity  , but we also lose the capability of people to obtain income and food from coral reefs. Climatic instability, which leads to rising sea temperatures, causes corals to bleach.Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour.Bleached corals often die if the stress continues.Among... What will probably happen to coral species with the increasing threats? A) Decrease. B) Losing functions C) Disappearance. D) Existence

(Question)
Before 1900, many theories existed as to the cause of yellow fever  . Some doctors were sure the disease was air-borne; others felt that it was spread from person to person. Dr. Carlos Finlay, a well-known Cuban doctor of that time, had long held the theory that it was caused by the bite of mosquitoes. But neither the public nor the doctors then accepted his idea.    Walter Reed,all American doctor sent to study yellow fever in Cuba,went to talk with Finlay.Reed,after reading a lot on the subject,had begun to think that Dr.Finlay might be fight.Then Reed and his comrades set to work at once.Outside Havana,they set up a laboratory and began experiments to test the theory.The experiments were successful.Now we know:A period of about two weeks must pass before a mosquito,after feeding on a sick person,could infect  another person.The sick person had to have yellow fever a certain number of days before the mosquito biting him was able to carry the disease. Reed proved the theory  _  . A) in his American lab B) by talking with Finlay C) in a kind of scientific Way D) by reading a lot of articles

Ques: My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: "What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?" He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation  is incredible  . We're on a more different curve than we used to be. One thing I'm looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you'll be able to sample things before you buy them. But the question will be how I find what I'm looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded  , with whom I might really want to communicate? I want to find those people but it's hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It's going to be very interesting, I think. The writer is looking forward to some real software agents so as to    _   . A) earn a lot of money B) communicate with some like-minded people C) help find the correct information needed D) spare some time for surfing the Internet

(Q).
Americans like to travel on their yearly holiday. Today, more and more travelers in the United States are spending nights at small houses or inns   instead of hotels. They get a room for the night and the breakfast the next morning. Rooms for the night in private homes with breakfast have been popular with travelers in Europe for many years. In the past five to ten years, these bedandbreakfast places have become popular in the United States. Many of these America's bedandbreakfast inns are old historic buildings. Some bedandbreakfast inns have only a few rooms. Others are much larger. Some inns do not provide telephones or televisions in the rooms, others do. Staying at a bedandbreakfast inn is much different from staying at a hotel. Usually the cost is much less. Staying at an inn is almost like visiting someone's home. The owners are glad to tell about the areas and the interesting places to visit. Many vacationists say they enjoy the chance to meet local families. Americans take a holiday trip   _  . A) every year B) for years C) all the year round D) every other year

Most people think that the capital of the movie world is Hollyhood, in the United States. However, the real movie capital is Mumbai, in India. Mumbai used to be known as Bombay, and so the film industry there is called "Bollywood." Bollywood makes twice as many movies each year as Hollyhood--more than 800 films a year. The movies from Bollywood are very different from Hollywood movies. For one thing, Bollywood movies are much longer than most Hollywood movies. Most Bollywood movies are more than three hours long, and contain singing, dancing, action, adventure, mystery, and romance (but usually no kissing). Because Bollywood films contain so many different features, this style of film is sometimes called a "masala" film. ("Masala" is an Indian word for a mixture of spices.) Another big difference between Bollywood and Hollywood movies is the way movies are made. It takes much longer to make a movie in Hollywood than in Bollywood. In fact, filming may begin on a Bollywood movie before the script even finished. The director and writers can make up the story while the film is being made. Sometimes they will even write the script by hand instead of taking time to type it. Bollywood actors are very popular and some are in such high demand that they may work on several movies at the same time. They may even shoot scenes for several films on the same day using the same costumes and scenery. Since most Bollywood movies follow the same kind of story, shooting scenes for several films at the same time is not a big problem for actors or directors. This also helps keep the cost of Bollywood movies lower than the cost of Hollywood movies. The average Bollywood film, with a budget of only two million U.S. dollars, seems very cheap compared to the average budget of sixty million U.S. dollars for a Hollywood film--thirty times as much! What is the main topic of the reading? A) famous stars in Bollywood B) how Hollywood movies are made C) the differences between two movie industries D) the history of movie-making in India
