Fr peple wh never cmplain abut the cld, can take r leave shwers and wuld get used t nises, ideal jbs have cme up. A heritage charity is advertising vacancies at the bttm f the wrld. Based in Antarctica, successful applicants will have t adapt t near-cnstant daylight, subzer temperatures and n flushing tilet r running water. But what incredible upsides: penguins and breathtaking landscapes in the plar area.
The UK Antarctic heritage Trust said it was seeking“ passinate adventurers ready t take n the challenge f a lifetime” in jbs that included managing a museum, pst ffice and gift shp as well as cnducting penguin cunts. Thse selected will live and wrk at Base A at Prt Lckry n Gudier Island.
Bridie Martin-West, a 33-year-ld midwife, is the current base leader. She said. “We get the wnder f seeing humpback and minke whales g past. On ne side f the island we have the mst majestic muntain range and n the ther side we’ve gt a glacier with icebergs. It is really raw nature and stunningly beautiful.”
The team arrived n the island at the same time as gent penguins fr their breeding seasn. The penguins are knwn fr their lud, head-back trumpet call, but Martin-West said, “Having cme frm living in Lndn it is still much quieter here…”
A typical evening might be watching films, playing bard games r carrying n an Antarctic traditin f peple giving presentatins n subjects they knw smething abut.
Applicatins were pened yesterday t UK residents, with training beginning in August. There will be interviews and selectin events befre then. Martin-West recalled being asked t put up tents blindfld while wearing ven glves. She said, “The training was like a crss between bt camp and a reality TV shw. It is very full n. It is a lt f wrk, sme f which is quite physical.”

【答案】4. B 5. B 6. D 7. C
【解析】
【导语】这是一篇说明文。文章主要讲述了南极独特的、有亮点的工作机会正在等待冒险者。
【4题详解】
词句猜测题。根据上文“Based in Antarctica, successful applicants will have t adapt t near-cnstant daylight, subzer temperatures and n flushing tilet r running water.(成功的申请者将驻扎在南极，他们必须适应近乎持续的日光、零度以下的温度和没有冲水厕所或自来水的环境。)”和but可知，上文提到在南极做志愿者的缺点，转折之后应该是南极的工作有很多不可思议的优点，包括企鹅和极地地区令人叹为观止的风景。upside在这里指的是这些工作的优点或优势，与B项advantages（优点）意思一致。故选B。
【5题详解】
推理判断题。根据文章第四段“Having cme frm living in Lndn it is still much quieter here…(从伦敦来到这里，这里仍然要安静得多……)”可知，Martin-West从伦敦来，但岛上仍然比伦敦安静得多，这暗示了伦敦是一个比岛屿更嘈杂的地方。因此，我们可以从第四段得知伦敦比岛屿更嘈杂。故选B。
【6题详解】
推理判断题。根据文章最后一段“Applicatins were pened yesterday t UK residents, with training beginning in August. There will be interviews and selectin events befre then. Martin-West recalled being asked t put up tents blindfld while wearing ven glves.( 昨天开始向英国居民开放申请，培训将于8月开始。在此之前将进行面试和选拔活动。Martin-West回忆说，她曾被要求戴着眼罩，戴着烤箱手套搭帐篷。)”可知，申请者需要进行培训和面试，其中包括戴着眼罩穿着烤箱手套搭帐篷等体力活动，说明这份工作对申请者的要求很高，因此最能描述这份工作的词是demanding（要求高的）。故选D。
【7题详解】
主旨大意题。文章开头就提到“Fr peple wh never cmplain abut the cld, can take r leave shwers and wuld get used t nises, ideal jbs have cme up(对于那些不怕冷、能洗澡也能适应噪音的人来说，理想的工作机会已经到来。)”，接下来文章介绍了南极的遗产慈善机构正在招聘志愿者，这些工作位于南极，需要适应极端的环境，但也有很多独特的优点，如看到企鹅和壮丽的极地景观。因此，文章主要讲述了南极独特的、有亮点的工作机会正在等待冒险者。因此，C选项：Unique Antarctic Jbs with highlights are waiting fr adventurers(独特的南极工作机会正在等待冒险者)是正确答案。故选C。
C
The launch f a tl t recrd a vanishing Greek dialect drew attentin back this week t ne f the great extinctins f the mdern wrld: nine languages are believed t be disappearing every year. Rmeyka, which is spken by an ageing ppulatin f a few thusand peple in the muntain villages near Turkey’s Black Sea cast, separated frm mdern Greek thusands f years ag. It has n written frm. Fr linguists, it is a“ living bridge” t the ancient Greek wrld, the lss f which wuld clearly be a blw.
But sme languages are in even bigger truble, with 350 that have fewer than 50 native speakers and 46 that have just ne. A cperatin between Australian and British institutins paints the situatin in distinct clurs, with a language stripes chart, devised t illustrate the accelerating decline in each decade between 1700 and tday. Its authrs predict that between 50% and 90% f the wrld’s 7,000 languages will be extinct by 2150. Even nw, half f the peple n the planet speak just 24 f them.
The histry f languages has always been linked t clnialism (殖民主义) and plitical persecutin (迫害), which scatter ppulatins as well as cntrlling them. The Endangered Languages Alliance (ELA) has tracked dwn and mapped hundreds f dying languages in New Yrk, which is an unexpected discvery. These dialects are suppsed t be fund in remte rural areas. Amng ELA’s mre shcking discveries is that, f 700 surviving speakers f Seke, which riginated in a cluster f muntain villages in Nepal, mre than 150 can be traced t tw apartment buildings in Brklyn district f New Yrk.
Frm Sami reindeer herders acrss the Arctic t Australia’s Indigenus (土著的) peples, the ways in which peple express themselves hide secret messages abut ancient ways f living in nature. Bth a will and a way are needed if they are t survive. By simply hnuring their existence, linguists play an imprtant rle. Ken Hale, an activist wh is strngly fr preserving endangered languages famusly argued that lsing any language was “like drpping a bmb n the Luvre”.
8. What des “Rmeyka” in Paragraph 1 refer t?
A. An extinct ancient Greek language.
B. A language with very few written wrds.
C. A disappearing dialect related t ancient Greek.
D. A ppular dialect lved by the yung generatin.
9. Why are the numbers used in Paragraph 2?
A. T shw the imprtance f the dialects.B. T cnclude the diversity f the dialects.
C. T explain different ways t prtect dialects.D. T illustrate the tendency f fast dying dialects.
10. What can we infer frm Paragraph 3?
A. Seke is a place in the muntains f Nepal.
B. Peple assume fewer dialects exist in big cities.
C. Nepal and New Yrk were twin cities many years ag.
D. ELA is nt surprised t trace an riginal Nepal dialect t Brklyn.
11. What des Ken Hale’s qute mean?
A. The extinctin f a dialect is a great lss.
B. Bmbing Luver is a disaster t any language.
C. Ancient ways f living are kept secret in Luvre.
D. Languages are t survive simply by hnring them.
【答案】8. C 9. D 10. B 11. A
【解析】
【导语】这是一篇说明文。本文讨论了全球濒危语言的现状及保护它们的重要性。
【8题详解】
词句猜测题。根据文章第一段“which is spken by an ageing ppulatin f a few thusand peple in the muntain villages near Turkey’s Black Sea cast, separated frm mdern Greek thusands f years ag. It has n written frm. Fr linguists, it is a“ living bridge” t the ancient Greek wrld, the lss f which wuld clearly be a blw.(是由土耳其黑海沿岸山区村落中几千名老年人口使用的语言，与现代希腊语分离了几千年。它没有书面形式。对于语言学家来说，它是通往古希腊世界的“活桥梁”，失去它显然是一个打击。)”可知，Rmeyka是一种与现代希腊语分离了几千年的方言，没有书面形式，对于语言学家来说，它是通往古希腊世界的“活桥梁”，失去它显然是一个打击。因此，Rmeyka指的是一种正在消失的与古希腊有关的方言。故选C。
【9题详解】
推理判断题。根据文章第二段“But sme languages are in even bigger truble, with 350 that have fewer than 50 native speakers and 46 that have just ne. A cperatin between Australian and British institutins paints the situatin in distinct clurs, with a language stripes chart, devised t illustrate the accelerating decline in each decade between 1700 and tday. Its authrs predict that between 50% and 90% f the wrld’s 7,000 languages will be extinct by 2150. Even nw, half f the peple n the planet speak just 24 f them.(但是有些语言面临着更大的麻烦，有350种语言的母语使用者不到50人，有46种语言的母语使用者只有1人。澳大利亚和英国机构之间的合作以不同的颜色描绘了这种情况，并设计了一张语言条纹图，以说明从1700年到今天，每个十年间都在加速下降的趋势。该图的作者预测，到2150年，世界上7000种语言中将有50%至90%灭绝。即使现在，地球上也有一半人只使用这24种语言。)”可知，使用数字是为了说明方言快速消亡的趋势。故选D。
【10题详解】
推理判断题。根据文章第三段“These dialects are suppsed t be fund in remte rural areas. Amng ELA’s mre shcking discveries is that, f 700 surviving speakers f Seke, which riginated in a cluster f muntain villages in Nepal, mre than 150 can be traced t tw apartment buildings in Brklyn district f New Yrk.(这些方言本应出现在偏远的农村地区。ELA更惊人的发现之一是，尼泊尔一群山村中起源的塞克语（Seke）有700名幸存者，其中一半以上的人住在纽约市，他们中的许多人甚至不知道自己是说这种语言的人。)”可知人们认为这些方言应该存在于偏远的农村地区，但令人震惊的是，在纽约布鲁克林区的两栋公寓大楼里，可以找到700名幸存的Seke方言使用者中的150多人。这表明人们认为大城市中方言的数量较少，但实际上并非如此。故选B。
【11题详解】
词句猜测题。根据文章最后一段“Ken Hale, an activist wh is strngly fr preserving endangered languages famusly argued that lsing any language was “like drpping a bmb n the Luvre”.( 以积极保护濒危语言而闻名的肯·黑尔（Ken Hale）曾激烈地表示，失去任何一种语言“就像是在卢浮宫投下一颗炸弹”。)”可知，Ken Hale的引用“lsing any language was ‘like drpping a bmb n the Luvre’”意味着失去任何一种语言都是巨大的损失，就像对卢浮宫投下炸弹一样。因此，A选项“方言的灭绝是巨大的损失”是正确的解释。故选A。
D
Have yu ever wrried that yu might smell bad? Well, yu d have a smell, but nt in the way yu think. The human bdy releases hundreds f chemical cmpunds int the air every day, and these cmpunds reveal much mre than just ur health habits; they can als indicate ur health situatins.
In 1971, chemist Linus Pauling identified 250 different gaseus chemicals in ur breath, knwn as VOCs. These VOCs riginate frm the bdy’s metablic (新陈代谢) prcesses and are excreted (排泄) thrugh skin glands. While sweat cntributes t these VOCs, it nly accunts fr a small prtin f them.
VOCs can reveal a lt abut ur health. Fr example, a sweet-smelling breath culd be a sign f diabetes. Besides breath, VOCs are als released frm ur skin, and feces (粪便). A ntable case invlved Jy Milne, wh nticed a change in her husband’s scent 12 years befre he was diagnsed with Parkinsn’s disease. Knwn as “the wman wh can smell Parkinsn’s,” Jy has been using her keen sense f smell t help scientists develp a simple swab test t diagnse the illnesses.
Animals with advanced sense f smell, like dgs, have demnstrated they can detect varius types f cancer in humans. Althugh these scents are ften undetectable t the human nse, they prvide evidence that ur bdies emit different scents when smething is wrng.
The relatinship between VOCs, and ur health is still being studied. Studies have already shwn that they can predict a persn’s age within a few years based n their skin VOC prfile. In ne interview, Prfessr Mrin stated, “We are at a relatively early stage in this research area, but we have already distinguished males frm females based n the acidity f skin VOCs. We believe skin VOCs can reveal aspects f wh we are, such as nutritin, health and stress. These signatures likely cntain markers that can be used t diagnse disease.”
S, wh knws—maybe ne day we will be able t detect diseases simply by breathing int a device.
12. What d we learn abut the VOCs accrding t the text?
A. The VOCs are primarily cmpsed f sweat.
B. Skin VOCs reveal mre abut ur health habits.
C. Our bdy’s metablic prcesses are the surce f VOCs.
D. VOCs nly released frm ur skin indicate health status.
13. Why des the authr mentin animals in paragraph 4?
A. T argue we shuld rely mre n animals.
B. T shw the superir intelligence f animals.
C. T highlight VOCs’ ptential as diagnstic markers.
D. T illustrate VOCs have the capability t cure cancers.
14. What future technlgy might arise frm the understanding f VOCs?
A. Devices that can breathe ut disease-causing VOCs.
B. Equipment that can analyze VOCs t diagnse diseases.
C. Persnalized perfumes that can mask disease-related VOCs.
D. Advanced facilities that can use VOCs t cure diseases.
15. Which can be a suitable title fr the passage?
A. The Rle f Sweat in Human HealthB. Linus Pauling’s Cntributins t VOCS
C. Smell f Bdy Cntributing t DiseasesD. Detecting Diseases thrugh Bdy Scents
【答案】12. C 13. C 14. B 15. D
【解析】
【导语】本文为一篇说明文。文章介绍了人体释放的VOCs与健康状况之间的关系，解释了这些化学物质的来源、它如何揭示健康信息，以及科研人员如何利用这些信息探索疾病诊断的可能性。
【12题详解】
细节理解题。根据文章第二段“These VOCs riginate frm the bdy’s metablic (新陈代谢) prcesses and are excreted (排泄) thrugh skin glands. (这些挥发性有机化合物来源于人体的代谢过程，并通过皮肤腺体排出体外。)”可知，我们身体的代谢过程是这些发挥性有机化合物的来源。故选C。
【13题详解】
推理判断题。根据文章第四段“Animals with advanced sense f smell, like dgs, have demnstrated they can detect varius types f cancer in humans. Althugh these scents are ften undetectable t the human nse, they prvide evidence that ur bdies emit different scents when smething is wrng. (具有高级嗅觉的动物，如狗，已经证明它们可以检测出人类的各种癌症。虽然这些气味通常是人的鼻子无法察觉的，但它们提供了证据，表明我们的身体在出现问题时会发出不同的气味。)”可知，作者提到像狗这样的动物是为了强调VOCs作为疾病诊断标记的潜力，因为这些动物能够嗅出人类身上的不同疾病，说明VOCs确实携带了与健康相关的信息。故选C。
【14题详解】
推理判断题。根据文章最后一段“S, wh knws—maybe ne day we will be able t detect diseases simply by breathing int a device. (所以，谁知道呢——也许有一天我们可以通过对着一个设备呼吸来检测疾病。)”可知，未来可能产生的技术是能够分析VOCs来诊断疾病的设备。故选B。
【15题详解】
主旨大意题。根据文章第一段“The human bdy releases hundreds f chemical cmpunds int the air every day, and these cmpunds reveal much mre than just ur health habits; they can als indicate ur health situatins. (人体每天向空气中释放数百种化合物，这些化合物揭示的不仅仅是我们的健康习惯；它们也可以表明我们的健康状况。)”以及全文内容可知，本文主要围绕着人体释放的VOCs如何反映健康状况，并有可能成为疾病诊断的工具这一主题展开。因此合适的标题为“Detecting Diseases thrugh Bdy Scents”。故选D。

【导语】本文是说明文。文章主要介绍了体育活动对学习和大脑功能的影响，并提供了一些建议，如在学习时进行轻度运动、在桌边进行锻炼、休息时散步以及保持锻炼的一致性。
【16题详解】
根据前文“Studies have shwn that physical activity can imprve mental alertness and cgnitive functin. Yur brain wrks better and yu can think mre clearly after exercising.(研究表明，体育活动可以提高精神警觉性和认知功能。锻炼后，你的大脑工作得更好，思维也更清晰)”可知，此处都在讲述运动对学习的好处，所以F项“Physical activity als helps bst memry and recall, which is imprtant when studying.(体育活动也有助于提高记忆和回忆，这在学习时很重要)”也是讲述运动对学习的好处，其中的als承接上文，符合文意。故选F项。
