As Rendall and his friend Bourke were searching for holiday gifts, they came across a lion cub (幼兽) for sale in a store in London. They bought it and named it Christian. It was a lovely animal, full of character. They looked after Christian for about a year, during which time an amazing bond formed between the two men and the lion. The three of them shared a flat over a furniture shop on London's King's Road, where cute and intelligent Christian quickly became a local celebrity, cruising (开车兜风) the streets in the back of a Bentley, popping for lunch at a local restaurant, and even posing for a fashion advertisement.
But soon, Christian outgrew Rendall's flat and soon even the church garden where he went for exercise wasn't large enough for him. They realized that their pet needed to be among other lions and deserved to live free in his natural environment. With their friends' help, Rendall and Bourke took Christian to Kenya and placed it under the expert care of “the father of lions” George Adamson, where the two would introduce Christian to the wild. Rendall and Bourke spent several months with Christian, helping him adapt to the new living environment, and then left unwillingly. A year later, they went back to Kenya, hoping to find the lion. When they finally found Christian, incredibly, Christian walked over slowly. Then suddenly he recognized them! He ran over and jumped up on them. They received a loving welcome from their lion, who was fit in with Africa and a life with other lions in the wild.
Rendall and Bourke's extraordinary reunion with Christian was filmed and is subject of a wonderful documentary and a book. The film of their reunion was found on a Japanese blog and posted on YouTube accompanied by I Will Always Love You, sung by Whitney Houston. The clip of the reunion was recently placed on YouTube and has received over 45 million hits.

In 1999, Giuliana Furci, founder and founding director of the Fungi (真菌) Foundation, developed a deep interest in fungi. They were everywhere, and the 20 year old took particular joy in the variety of mushrooms: small and button shaped; tall and umbrella like; round with red caps topped with white flakes. Some were commonly found in people's diets, for they were rich in nutrients such as vitamin, fiber, minerals and protein.
But Furci also quickly realized that these fungi went largely ignored in Chile, where there were few guidebooks and an almost total lack of policies and resources to protect them from over harvesting and other human activities. Determined to correct this, Furci wrote a field guide and set up the Fungi Foundation—a non profit organization dedicated to fungi conservation. In her guide, special attention went to the role of fungi in the ecosystem.
“Life on the planet wouldn't exist without fungi,” said Greg Mueller, a mushroom conservation expert. “Because of their relationship with forests and trees, we can't survive without fungi. In terms of the health of the planet, they're incredibly important to humans and the overall ecosystem.” Fungi can break down plants and animals, thus cycling nutrients and increasing their availability in the soil. They are also important contributors to the soil carbon stock through the same process. What's more, fungi have been found to help degrade (降解) various pollutants, such as plastic. And mycelium (菌丝体), which is the root structure of mushrooms, is now being used to replace unsustainable materials, such as plastic and animal based products.
Because of these, exploration of fungi was expanded at a faster pace. However, some were already listed as critically endangered. In 2010, Furci took an even bigger step—with other environmental non profit organization, she put forward a proposal for the government to systematically assess how large new developments such as housing, dams, and highways affect fungi. In 2012, a law was passed and Chile became the first country in the world to protect fungi by law.
5. What can we learn about Furci from the first two paragraphs
A. She enjoyed collecting mushrooms.
B. She was fond of cooking mushrooms.
C. She worried about the situation of fungi.
D. She had a habit of writing field guidebooks.
6. What is paragraph 3 of the text mainly about
A. The life on the Earth without fungi.
B. The importance of fungi on the Earth.
C. The relations between trees and fungi.
D. The practical uses of fungi in the future.
7. How did Furci protect the ecosystem
A. By writing free instructions on plants.
B. By starting a non profit ecotourism company.
C. By raising awareness of the importance of fungi.
D. By passing laws to ban over harvesting mushrooms.
8. Which of the following best describes Furci's work
A. Ground breaking. B. Debatable.
C. Romantic. D. Unmatched.
答案及解析:本文是一篇说明文。文章主要讲述Furci意识到真菌对地球上生命的重要性后通过写指南、成立基金会等方式来呼吁人们关注并保护真菌。她和其他环保组织的行为甚至促使智利通过了一项保护真菌的法律。
5. C 细节理解题。根据第二段中的“But Furci also quickly realized that these fungi…from over harvesting and other human activities. (但Furci也很快意识到,这些真菌在智利基本上被忽视了,那里几乎没有指南,几乎完全缺乏政策和资源来保护它们免受过度采集和其他人类活动的影响。)”可知,Furci担心真菌的现状。故选C。
6. B 段落大意题。根据本段第一句“‘Life on the planet wouldn't exist without fungi,’ said Greg Mueller, a mushroom conservation expert. (‘如果没有真菌,地球上的生命就不会存在,’蘑菇保护专家Greg Mueller说。)”并结合本段其他内容可知,本段主要介绍了真菌对地球上生命的重要性。故选B。
7. C 推理判断题。根据第二段中的“Determined to correct this, Furci wrote a field guide and set up the Fungi Foundation—a non profit organization dedicated to fungi conservation. In her guide, special attention went to the role of fungi in the ecosystem.(为了纠正这一点,Furci写了一本野外指南,并成立了真菌基金会——一个致力于真菌保护的非营利组织。在她的指南中,特别关注了真菌在生态系统中的作用。)”可知,为了保护真菌,Furci写了指南并成立了真菌基金会。由此推知,Furci通过提高人们对真菌重要性的认识来保护真菌。故选C。
8. A 推理判断题。根据最后一段中的“In 2010, Furci took an even bigger step…Chile became the first country in the world to protect fungi by law.(2010年,Furci与其他环保非营利组织一起迈出了更大的一步,她向政府提出了一项建议,要求政府系统评估住房、水坝和高速公路等大型新开发项目对真菌的影响。2012年,智利通过了一项法律,成为世界上第一个以法律保护真菌的国家。)”可知,Furci和其他环保组织的行为甚至促使智利通过一项保护真菌的法律。由此推知,Furci的工作是有开拓性的。故选A。

A seed bank stores seeds to preserve genetic diversity; hence it is a type of gene bank. Many people may wonder 1.__________ the seeds are stored. One of the major reasons is to preserve the genes that plant growers need to increase yield (产量), disease resistance, drought tolerance, nutritional quality, and the taste of crops. Another is to prevent 2.__________ (lose) of genetic diversity in rare or endangered plant species in 3.__________ effort to conserve biodiversity. Many plants 4.__________ (grow) centuries ago by humans are used less frequently now;

答案及解析:本文是一篇说明文。文章介绍了“种子银行”。
1. why 考查名词性从句。句意:许多人可能想知道为什么要储存种子。“1.__________ the seeds are stored”在句中作动词wonder的宾语从句,设空处在从句中作状语,根据句意可知此处应使用why引导名词性从句,表示“为什么,……的原因”。故填why。
2. loss 考查名词。句意:另一个原因是防止稀有或濒危植物物种的遗传多样性丧失,努力保护生物多样性。设空处在句中作动词prevent的宾语,应填动词lose的名词loss。故填loss。
3. an 考查冠词。句意同上。effort“艰难的尝试,试图,尽力”为可数名词,此处表泛指,应填不定冠词;固定短语in an effort to do sth.,意为“为了达到……目标,为了……”,空后effort以元音音素开头,设空处应填不定冠词an。故填an。
4. grown 考查非谓语动词。句意:人类在几个世纪前种植的许多植物现在使用的频率较低;种子“银行”提供了一种保护历史和文化价值的方法。“4.__________ (grow) centuries ago by humans”作后置定语修饰名词短语Many plants,Many plants与动词grow构成逻辑上的被动关系,结合空后的“centuries ago by humans”可知设空处应填grow的过去分词表被动。故填grown。
5. at 考查介词。句意:在恒定的低温和低水位条件下保存的种子可以防止遗传资源的减少,而这些遗传资源是在田间收集中保存的。句中指“在恒定的低温低水位状态下保存”,“在……温度/水位”用介词at与temperature和water level进行搭配。故填at。
6. be damaged 考查动词的语态。句意:这些可供选择的“活”收藏品可能会因自然灾害、疾病暴发或战争而受损。设空处在句中与can构成谓语,主语These alternative “living” collections与动词damage之间为被动关系,由情态动词can可知设空处应填be done构成被动语态。故填be damaged。
7. or 考查连词。句意同上。句中natural disasters, outbreaks of disease与war之间为并列关系,设空处应填连词连接三种可能的情况,连词or“或者”符合句意。故填or。
8. libraries 考查可数名词复数。句意:种子“银行”包含了减少植物压力的进化策略的宝贵信息,被认为是种子库,可以帮助创造现有种子的转基因版本。library为可数名词,根据句中的“seed banks”可知此处应填library的复数形式。故填libraries。
9. existing 考查形容词。句意同上。设空处在句中作定语修饰名词seeds,形容词existing“现存的”符合句意。故填existing。
10. publicly 考查副词。句意:大多数种子“银行”是公共资助的,种子通常用于造福公众的研究。设空处修饰谓语动词are funded,应填public的副词publicly。故填publicly。
