一、阅读理解
Earth is far mre alive than we previusly thught, accrding t “deep life” studies that reveal a rich undergrund ecsystem beneath ur feet that is almst twice the size f all the wrld’s ceans. Despite extreme heat, n light and intense pressure, scientists estimate it has between 15 billin and 23 billin tnnes f micrrganisms. “It’s like finding a whle new reservir (储藏) f life n Earth,” said Karen Llyd an assciate prfessr at the University f Tennessee.
Results suggest 70 percent f Earth’s bacteria and archaea exist in the subsurface. One rganism fund 2.5 kilmeters belw the surface has been buried fr millins f years and may nt rely at all n energy frm the sun. Als, the methangen (产甲烷菌) has fund a way t create methane in this envirnment, which the methangen may nt use t reprduce r divide, but use t replace r repair brken parts. Lengths f their lives were cmpletely different. Sme micrrganisms have been alive fr thusands f years, barely mving except with shifts in earthquakes r eruptins. They’re just active inside, with less energy than peple thught pssible t supprt life.
The team cnsists f 1,200 scientists frm 52 cuntries in disciplines ranging frm gelgy and micrbilgy t chemistry and physics. A year befre the cnclusin f their study, they will present the findings befre the American Gephysical Unin’s annual meeting pens this week, which they say are made pssible by technical advances n drills and micrscpes.
The scientists have been wndering abut the pint beynd which life cannt exist, but the deeper they dig, the mre life they find. There is a temperature maximum — currently 122℃ — but they believe this recrd will be brken if they keep explring and develping mre advanced instruments.
Questins remain, including hw the micrbes interact with chemical prcesses, and what this might reveal abut hw life and Earth c-evlved.
1．What d the scientists find abut the undergrund rganisms?
A．They can’t reprduce and divide.B．They’re the ldest living things.
C．Sme f them cnsume n energy.D．Sme f them almst always keep still.
2．What can we learn abut the research frm paragraph 3?
A．It lasts fr arund ne year.B．It invlves effrts frm many fields.
C．It prmtes technical develpment.D．It is cnducted in 52 cuntries.
3．Why d the scientists dig deep?
A．T break their previus recrd.
B．T find the depth limit f life.
C．T discver mre ancient micrrganisms.
D．T measure the highest subsurface temperature.
4．Which f the fllwing can be the best title?
A．Earth Depths Are Full f Life
B．Organisms Live Better Undergrund
C．Earth Is Far Beynd Human Explratin
D．Subsurface Life Differs frm That n Land
二、七选五
During winter, when it is cld and freezing utside, all we want t d is stay wrapped up in ur blankets and remain in bed. 5 During times like these, ne might envy animals like bears, wh dze thrugh the cldest seasn and wake up fresh in the spring. But hw d they g withut fd fr such a lng time?
6 Because f terrible weather and shrtages f fd, certain animals hibernate (冬眠) t save energy and survive. Hibernatin invlves a significant slwdwn f the metablism (新陈代谢) and a drp in bdy temperature. Reducing their metablism allws these animals t cnserve energy during thse lng cld mnths.
T understand the need fr hibernatin, we first must understand the difference between endthermic and ectthermic rganisms. Ecttherms are thse animals whse bdy temperatures depend n the surrunding temperature. 7 Usually, they have a bdy temperature that changes with the temperature f their envirnment. They depend n things like sunlight r the surface f heated rcks t warm up. 8 They are als knwn as “cld-blded” animals, which include fish, amphibians, and reptiles.
On the cntrary, endtherms can regulate their wn bdy temperature by generating internal heat. They are capable f maintaining their physilgical bdy temperature in a stable range, regardless f the changes in the envirnment. Endtherms adjust their metablic heat prductin and insulatin t stay warm, whereas during ht weather, they sweat t cl dwn. Endtherms are capable f maintaining a steady temperature as cmpared t their changing surrundings. They are called “warm-blded” animals, and include mammals and birds. 9
A．Cnversely, they seek shade t cl dwn.
B．A cup f ndles r ht chclate als helps.
C．Mst animals usually try t gain as much weight as they can befre they hibernate.
D．Hibernatin is an energy-saving adaptatin t prtect against unpleasant cnditins.
E．Thus, many animals hibernate t save energy and survive these bad winter cnditins.
F．Metablism is the prcess thrugh which ur bdy changes the fd we eat int energy.
G．This means that they depend n their external envirnment t regulate their bdy temperature.

【导语】本文是一篇说明文。科学家对地球深部生命展开了“深层生命”研究，揭示了我们脚下一个丰富的地下生态系统，其大小近乎是全球海洋大小的两倍。
1．细节理解题。根据第二段中“Sme micrrganisms have been alive fr thusands f years, barely mving except with shifts in earthquakes r eruptins. (有些微生物已经存活了数千年，除了地震或火山爆发的变化，它们几乎没有移动过。)”可知，有些微生物基本上是没有移动过的。故选D。
2．细节理解题。根据第三段中“The team cnsists f 1,200 scientists frm 52 cuntries in disciplines ranging frm gelgy and micrbilgy t chemistry and physics. (该团队由来自52个国家的1200名科学家组成，他们的学科从地质学、微生物学到化学和物理学。)”可知，该研究团队是由来自52个国家的1200名科学家组成，他们的学科从地质学、微生物学到化学和物理学即该研究涉及许多领域的努力。故选B。
3．细节理解题。根据倒数第二段中“The scientists have been wndering abut the pint beynd which life cannt exist, but the deeper they dig, the mre life they find. (科学家们一直想知道生命不可能存在的临界点，但他们挖得越深，发现的生命就越多。)”可知，研究者们一直深挖的理由在于探索生命寻深度极限。故选B。
4．主旨大意题。根据第一段中“Earth is far mre alive than we previusly thught, accrding t “deep life” studies that reveal a rich undergrund ecsystem beneath ur feet that is almst twice the size f all the wrld’s ceans. (根据“深层生命”研究，地球比我们以前想象的要活跃得多，我们脚下有一个丰富的地下生态系统，几乎是世界上所有海洋的两倍大。)”以及通读全文可知，文章介绍的是科学家对地球深部生命展开了“深层生命”研究，揭示了我们脚下一个丰富的地下生态系统，其大小近乎是全球海洋大小的两倍。结果表明，地球 70% 的细菌和古菌存在于地下，一些微生物已经存活了数千年，仅在地震或喷发时才移动。虽然存在极端高温、无光和巨大的压力，但科学家估计约有 150 至 230 亿吨微生物和细菌在地下生活。这项成果发表在美国地球物理联合会年会上。故A选项“Earth Depths Are Full f Life.(地球深处充满了生命。)”概括文章主旨，符合标题。故选A。
5．B 6．D 7．G 8．A 9．E
【导语】本文是一篇说明文。文章主要介绍了动物冬眠的概念以及具体的原因。
5．根据上一句“During winter, when it is cld and freezing utside, all we want t d is stay wrapped up in ur blankets and remain in bed.(在冬天，当外面很冷的时候，我们想做的就是裹着毯子躺在床上。)”可知，下一句是对上一句补充说明，说明冬季特别冷的时候人类可以做的事。B项“A cup f ndles r ht chclate als helps.(一杯面条或热巧克力也有帮助。)”符合语境。故选B。
6．根据此段下文关键句“Hibernatin invlves a significant slwdwn f the metablism (新陈代谢) and a drp in bdy temperature.(冬眠意味着新陈代谢的显著减缓和体温的下降。)”可知，此段主要在讲什么是冬眠及其好处。D项“Hibernatin is an energy-saving adaptatin t prtect against unpleasant cnditins.(冬眠是一种节约能源的适应方式，以抵御不愉快的环境。)”在介绍冬眠的概念，符合语境。故选D。
7．根据上句“Ecttherms are thse animals whse bdy temperatures depend n the surrunding temperature.(变温动物是指体温取决于环境温度的动物。)”和下句“Usually, they have a bdy temperature that changes with the temperature f their envirnment. (通常，它们的体温会随着环境温度的变化而变化。)”可知，变温动物的体温随着环境温度的变化而变化。G项“This means that they depend n their external envirnment t regulate their bdy temperature.(这意味着它们依靠外部环境来调节体温。)”承上启下，同时G项中的“bdy temperature”与上下句中的“bdy temperatures”呼应。故选G。
8．根据上文“Usually, they have a bdy temperature that changes with the temperature f their envirnment. They depend n things like sunlight r the surface f heated rcks t warm up. (通常，它们的体温会随着环境温度的变化而变化。它们依靠阳光或加热的岩石表面来升温。)”可知，变温动物的体温随着环境温度的变化而变化，上文讲变温动物如何升温，可得出讲下文会介绍变温动物如何降温。A项“Cnversely, they seek shade t cl dwn.(相反，它们寻找阴凉的地方降温。)”与上一句构成转折关系。故选A。
9．此处位于句末以及文章最后一句，起总结作用，E项“Thus, many animals hibernate t save energy and survive these bad winter cnditins.(因此，许多动物冬眠是为了节省能量并在恶劣的冬季条件下生存。)”对全文进行总结。故选E。
10．B 11．A 12．D 13．A 14．C 15．C 16．B 17．D 18．B 19．C 20．C 21．D 22．A 23．C 24．D
