Article: Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday. Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa. "Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive species," Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report. The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats. "The remaining populations become surrounded in very small ecosystems, they have inbreeding problems ... and at the end these species may disappear," he added. Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi. The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence. Other consequences could include the spread of invasive species and infectious diseases, it said. The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves , inland waters, forests, savannahs and grasslands. The FAO also called for the creation of migration corridors for animals in areas where their movement was limited. The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed. It also urged local communities... Question: To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT _ . Options: A: restoring damaged ecosystems B: limiting world population growth C: creating movement channels for animals D: urging governments and local communities to take action

Article: The oldest and most common source of renewaBle energy known to man, Biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of Biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----Biomass promises to play a continuing role in providing power and heat for millions of people around the world. According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide , Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun's energy. In this way, Biomass serves as a sort of natural Battery for storing the sun's energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the "Battery" lasts forever. According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation's total electricity supply. In 2008----although the numBers aren't all in yet----wind power proBaBly took over first place Because of the rapid development of wind farms across the country. Producing power from Biomass helps reduce some 11 million tons of carBon dioxide each year. Some homeowners also try to make their own heat By using Biomass materials. Such practice may save homeowner's money, But it also produces a lot of pollution. So, the Best way is to encourage power plants to use it. Question: Why is Biomass considered as " a sort of natural Battery"? Options: A: It Burns merely plant matter. B: It keeps producing electricity. C: It stores the energy from the sun. D: It produces zero carBon dioxide.

Q: Read the article and select the best answer. Article: Over the past decade, cheating--an act of academic dishonesty--has become more and more common. The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and--even more surprising--often the best students cheat to get to the top of their class--and they don't think it is wrong. It's not a big deal. Everybody is doing it. It is a big deal! Cheating is basically wrong and must be punished. If students easily get away with it, they might be encouraged to do it again. They won't realize that this--in the broadest sense--is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior. If no one were punished for cheating, who would ever study for an exam? Tons of papers would be _ from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students--a rather bad precondition to enrich our society wisely and intelligently. Students have to learn that they have to learn. Only doing what's right will bring them a feeling of pride and accomplishment and create self-confidence--the building blocks for a successful and satisfying life and a society that keeps its values. Question: How do they make the students realize their misbehavior? Options: A: By letting them getting away with it. B: By telling them what is right. C: By catching them on the spot. D: By giving them some punishment.
A: D
