And just as important, he had a name, Ahmed, the elephant received the special treatment until his death in 1974, under an order from Kenya’s then－president Jomo Kenyatta. The name helped give Ahmed and, by extension, the cause of elephant conservation greater recognition. With Ahmed the elephant in mind, Kenya last week launched the Elephant Naming Festival in which people get the chance to adopt an elephant after contributing money toward their chosen animal’s conservation. The initiative gives the adoptive parent priority when it comes to choosing the first name of the elephant. The second name will be a Maasai(马赛族) one based on the animal’s profile, history, role in the family and physical attributes like the state of its tusks. Launching the program, Najib Balala, a top official at the Ministry for Tourism and Wildlife, said the elephant－naming initiative will bring greater awareness of the need for conservation and promote tourism. Balala said the event will be held each year on Aug 12, observed as World Elephant Day. “We feel that this is a great opportunity for everyone to be part of the sustainability of tourism and wildlife in Kenya for future generation，” Balala said. “Wildlife is a big part of Kenya’s heritage and ensuring that future generations enjoy this resource should always remain the most important. The launch of the Magical Kenya Elephant Naming Festival builds on the good work that the Kenya Wildlife Service and other partners have been doing over the years.” 1. What has the special treatment to Ahmed brought about? A. More people are willing to protect elephants. B. More people are anxious to collect tusks. C. More elephants are guarded by armed soldiers. D. More elephants are released to the wild. 2. What can adoptive parents do in the Elephant Naming Festival? A. Adopt an elephant according to its role in the family. B. Take priority for giving their elephant’s first name. C. Contribute money toward launching the initiative. D. Consult the elephant’s profile to give it the second name. 3.

To contribute to wildlife protection and sustainable tourism. D. To offer people a chance of naming and adopting an elephant. 4. What is Najib Balala’s attitude to the elephant－naming initiative? A. Supportive.　　　　 B. Objective. C. Doubtful. D. Disapproving. B Fast fashion has changed the way we dress. We buy more clothes, more often—but we wear them less. The average lifespan(寿命) of a garment(衣服) is just two years, and 87 per cent of our unwanted clothing ends up being buried underground or burned. Alina Bassi, founder of Kleiderly, wants to give our clothing waste another chance to be useful. The 30－year－old chemical engineer has always cared about the threat of climate change—in her teens she made a film highlighting the environmental impact of Heathrow Airport—but she actually started her career in the oil industry, at a consultancy specialising in offshore drilling platforms. “I learned so much there, but I knew it wasn’t quite right，” Bassi says. As a junior engineer, it was difficult to effect a change in large corporations, and she wanted to make an impact.“I really wanted to work in sustainability.” After a few more years in the energy industry，she landed at bio－bean, a start－up that turned waste coffee grounds into products that could be burned for heat and fuel. Then she found that used coffee grounds are not the biggest threat facing the planet. Instead, she poured her efforts into tackling a much bigger global polluter: the fashion industry. Using the principles of a circular economy, her company has developed a low－energy, multi－stage process to turn clothing fibres into an alternative to oil－based plastic. This plastic can then be used by manufacturers(制造商) in their existing machines, so that your old T－shirts and jeans are reused as brand－new products. “I wanted to take the fibres and turn them into something that would be used for many years to come，” Bassi says. With the rise in climate change activism, many fashion brands face external pressure to clean up their act, and Kleiderly has had interest from labels looking to recycle their clothing. 5. What does the first paragraph talk about? A. The harm of over－consumption. B. The fast－changing fashion trends. C. The new way of waste treatment. D. The huge waste in the fashion industry. 6. What do we know about Bassi’s first job? A. It went against her personal values. B. It inspired her to make a film. C. It drew her attention to climate change. D. It enabled her to effect a change in the oil industry. 7. What is the aim of Kleiderly? A. To create clothes meant to last. B. To lower the carbon impact of fashion. C. To use abandoned clothes to make oil. D. To reduce oil－based plastic in clothing making. 8. What is expected of Kleiderly? A. It will update manufacturers’ machines. B. It will put an end to climate change activism. C. It will do business with many fashion brands. D. It will face great external pressure. C NASA has observed a strange effect of human spaceflight: astronauts’ blood going backwards and clotting(凝固). The observations could have serious effects on plans to send astronauts to Mars and to allow tourism in space. An unnamed astronaut on the International Space Station (ISS) was carrying out a scan on his body—guided by experts on the ground. Similar tests before the astronaut went to space came back normal, but the scan taken in space revealed a clot of blood, appalling NASA doctors. “We were not expecting this. This has never been reported before，” said NASA scientist Karina Marshall－Goebel. The astronaut didn’t have any clot－related symptoms, but was given blood－thinning medication for the rest of his time in orbit to prevent more clots forming. NASA researchers then observed the jugular veins of 11 astronauts on the ISS, and in five of those 11 astronauts, blood flow in the jugular vein had stopped. The jugular vein is one of the most important parts of the body, which runs between the heart and the head, draining(使流走) deoxygenated blood from the brain. This “draining” process is an essential way to reduce pressure in the brain. Blood that doesn’t move normally through the body is a major concern because it can lead to clotting, which can cause more serious problems like damage to the lungs. The blood in the jugular vein also began moving in the opposite direction (from the heart towards the head) for two astronauts. NASA scientists described this as “extremely abnormal”， and said that the blood may have switched directions due to a blockage. A similar phenomenon has been observed on Earth for patients with tumours(肿瘤) that force blood to find a different route to the heart. “I think it was probably scary for everybody. But I think the fact that we found this now is really, really good news, because if you know this is a risk factor(因素) of spaceflight, it’s something that you can monitor and prevent，” said Ms Marshall－Goebel. 9. What does the underlined word “appalling” in Paragraph 2 mean? A. Relaxing. B. Embarrassing. C. Attracting. D. Shocking. 10. What can be learned about blood flow in the jugular vein? A. It seems to clot frequently. B. It keeps the brain oxygenated. C. It places great pressure on the brain. D. It usually runs from the heart to the head. 11. What might NASA scientists do next? A. Monitor various risk factors of spaceflight. B. Find ways to deal with astronauts’ blood clots. C. Create an Earth－like environment for astronauts. D. Explore reasons for the blood changing directions. 12. What’s the best title for the text? A. Astronauts’ Blood Flows Backwards in Space B. Astronauts’ Blocked Veins Bring Medical Insight C. Astronauts Experience Faster Blood Flow in Space　 D. Astronauts are Suffering from Serious Blood Diseases　 一.单句语法填空 1.had repaired 2.in 3.Suspected 4.is generated 5.by 6.to blame 7.primitively 8.detection 9.linking 10.by 11.existence 12.with 13.to 14.away 15.of 二.课文语法填空 1.a 2.medical 3.discoveries 4.to study 5.that 6.had appeared 7.differently 8.to 9.evolution 10.causing 三.阅读理解 答案与解析 【语篇解读】　本文是说明文。文章介绍了肯尼亚“大象命名节”的由来、活动内容和这一节日在肯尼亚旅游业可持续发展和野生动物保护中的作用。 1. 答案　A 解析　细节理解题。根据首段尾句“The name helped give Ahmed and, by extension, the cause of elephant conservation greater recognition.”可知，对Ahmed的特别待遇，使得更多的人愿意来保护大象，故选A项。 2. 答案　B 解析　细节理解题。根据第三段中“The initiative gives the adoptive parent priority when it comes to choosing the first name of the elephant.”可知，在“大象命名节”上，“养父母”可以给他们的大象起名字。故选B项。 3. 答案　C 解析　细节理解题。根据第四段首句“Launching the program, Najib Balala, a top official at the Ministry for Tourism and Wildlife, said the elephant－naming initiative will bring greater awareness of the need for conservation and promote tourism.”可知，举办“大象命名节”是为了促进野生动物的保护和旅游业的可持续发展。故选C项。 4. 答案　A 解析　观点态度题。根据第四段中的“will bring greater awareness”和第五段中的“this is a great opportunity”可知，这些评价都是对这一节日的作用的肯定，因此这位肯尼亚官员对该节日是支持的。故选A项。 答案与解析 【语篇解读】　本文是一篇新闻报道。心系环保事业的年轻工程师Alina Bassi创办公司，回收废旧衣物用于制造新产品，旨在降低时装业的碳足迹。 5. 答案　D 解析　段落大意题。第一段描写了时装行业惊人的浪费现象：我们买的衣服越来越多，买衣服的频率越来越高，却不怎么穿这些衣服，一件衣服的平均寿命只有两年，最终，那些被我们淘汰的衣服都被填埋或被焚烧了。 6. 答案　A 解析　推理判断题。根据第二段的内容可知，Bassi从青少年时期就心系环保事业，初入职场的Bassi在一家咨询公司做海上钻井平台相关工作，但她认为作为一名初级工程师，想要在大企业有所改变很困难，所以她想要在可持续发展行业谋职。由此可推知，在石油企业的工作与她的个人想法相悖。 7. 答案　B 解析　推理判断题。根据第二段中的“Alina Bassi, founder of Kleiderly, wants to give our clothing waste another chance to be useful.”，第三段中的“Instead, she ... tackling a much bigger global polluter: the fashion industry.”及第四段的内容可知，Kleiderly将废旧衣物的纤维制成一种不以石油为原料的塑料材料，工厂使用这种材料可以制造其他新产品。由此可知，该公司的宗旨是减少时装行业的碳排放。 8. 答案　C 解析　推理判断题。根据最后一段可知，气候变化行动给许多时装品牌带来了压力，Kleiderly表示了对这些品牌的兴趣。由此可推知，Kleiderly之后会与这些品牌有业务上的往来。 答案与解析 【语篇解读】　本文是一篇说明文。NASA科学家观察到一个奇怪的现象：宇航员在太空时血液会倒流并凝结成血块，这一现象是以前从未发现的。 9. 答案　D 解析　词义猜测题。根据画线单词前面的“Similar tests before the astronaut went to space came back normal, but”及其后面的“We were not expecting this. This has never been reported before”可知，去太空前的测试结果正常，而太空测试却显示宇航员血液凝结成血块，这一点NASA科学家没有预料到，以前也从未发现过，故可推知这一发现让NASA的医生很“震惊”。 10. 答案　B 解析　细节理解题。根据第四段中的“The jugular vein is one of the most important parts of the body, which runs between the heart and the head, draining deoxygenated blood from the brain.”可知，颈静脉是人体最重要的部位之一，它在心脏和头部之间循环，将缺氧血从大脑排出。由此可知，颈静脉会使大脑保持氧合。 11. 答案　B 解析　推理判断题。根据最后一段中的“if you know this is a risk factor of spaceflight, it’s something that you can monitor and prevent”可知，了解到太空飞行的这一危险因素，我们才有可能去监测并阻止这种情况的发生。由此可推知，科学家接下来很可能就是寻找应对这一问题的方法。 12. 答案　A 解析　标题归纳题。本文第一句就揭示了全文的主要内容，即宇航员在太空时血液会倒流并凝结成血块，故A项作标题最为恰当。 学科网（北京）股份有限公司 $
