【文章內(nèi)容簡(jiǎn)介】 o protect and maybe increase corals. One mon option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more handson methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year. To keep the wild ecosystem alive, Erinn Muller, the center39。s director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs. In The Bahamas, Ross Cunning, a research biologist at Chicago39。s Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn39。t. We think their ability to deal with these higher temperatures is built into their genes, says Cunning. There39。s evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.32. What does the underlined word halt in the first paragraph mean?A. End. B. Develop. C. Strengthen. D. Weaken.33. What do Muller and her team do to save corals?A. Restore the damaged reefs.B. Grow corals by hand underwater.C. Create more protected areas.D. Move corals to unpolluted areas.34. What do Cunning39。s words suggest?A. Many corals have been genetically improved.B. Cooling down the waters is key to rescuing corals.C. Reasons for corals surviving heat waves are shocking. D. The highest temperature corals can survive is unclear.35. Which can be a suitable title for the text?A. Relationship between corals and algaeB. Efforts made to save coralsC. Impact of climate warming on coralsD. Survival crisis faced by coral reefs答案：3235 ABDB解析：The soft creatures are naturally halftransparent and get their brilliant color from algae(藻類）living inside them和下文的the interdependent relationship with algae, typically pushing them out and turning white可知，珊瑚蟲因生活在它體內(nèi)的藻類獲得了絢麗的色彩，它們相互依賴，當(dāng)珊瑚蟲受到高溫或污染的壓力時(shí)，它們通常會(huì)將藻類驅(qū)逐出去，變成白色，故此處應(yīng)表示它們結(jié)束與藻類的相互依存的關(guān)系。end(使）結(jié)束，(使)停止可解釋畫線詞意思。harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea…on damaged reefs可知， Muller和她的團(tuán)隊(duì)正在采集那些在自然環(huán)境壓力下存活下來(lái)的珊瑚蟲樣本，在海底人工養(yǎng)殖它們，然后使它們重新回到珊瑚礁上生存。由此可知， Muller和她的團(tuán)隊(duì)在人工培育珊瑚蟲。39。s words可將解題依據(jù)定位至最后一段，根據(jù)最后一段的The big question scientists need investigate, adds Cunning, is how much more heat corals can adapt to可知，科學(xué)家還需要研究存活下來(lái)的珊瑚蟲還能適應(yīng)再高多少的溫度，即珊瑚蟲能適應(yīng)的最高溫度還是未知的。，文章首段介紹珊瑚礁面臨的困境，以引出文章的核心內(nèi)容:科學(xué)家們?yōu)榱苏壬汉鹘高M(jìn)行各種科學(xué)研究和做出種種努力，如建立海洋保護(hù)區(qū)、人工培育珊瑚蟲、研究具有耐高溫基因的珊瑚蟲等。故B項(xiàng)最適合作本文標(biāo)題。第二節(jié) （共5小題；每小題2分，滿分10分）根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。Endangered speciesAn endangered species is a group of animals that could soon bee extinct. ______36______ Many species are nearly extinct and could disappear off the face of the earth very soon if we don’t do anything to save them. There are many reasons why species bee endangered.Habitat destruction is the main reason why animals bee endangered and this happens in two ways. When humans move into a new area, the animals’ habitat is destroyed and there is nowhere for them to live and nothing to eat because humans chop down trees and build houses and farms. ______37______ Chemicals in rivers and poisons on farms cause the destruction of animals’ homes and food supplies._________38_________ Animals have been brought to the edge of extinction because they are killed for their highlyvalued meat, fur, bones or skin, or just for sport. Overfishing has resulted in many large sea creatures like whales and sharks being endangered species.________39________ We should take care not to pollute natural areas, and farmers or panies who destroy animal habitats should face severe financial penalties. The public can help out by refusing to buy any products made from these animals’ body parts. Governments can help, too, by making it against the law to hunt, fish or trade in endangered species. They can also provide funding for animal sanctuaries, to protect animals from extinction by breeding more endangered animals, which they later release into the wild. ______40______A. Animal habitats are also destroyed because of pollution.B. Endangered species are also the result of hunting and fishing.C. Eventually, all the creatures on Earth will enjoy being together.D. Recent changes, however, have helped to improve the situation.E So what can individuals and governments do to protect endangered species?F. Extinction happens when the last of the species has died out and there will be no more.G. If we all cooperate and take these steps, we will protect these animals for future generations.【答案】36. F 37.
