Ⅰ.补句子　析结构 1．Sitting back in my seat，I can’t quite believe that I’m about to travel(travel) along the railway that many foreign experts claimed(宣称) was “impossible”．(P82 Para.1) 结构分析：本句为主从复合句；Sitting back...为现在分词短语作伴随状语，第一个that引导宾语从句，作believe的宾语；第二个that引导定语从句，修饰先行词railway。 汉语翻译：靠坐在火车的座位上，我仍然不敢相信，我将要沿着许多外国专家声称“不可能建成”的铁路开始一段旅程。 2．The words “railways like massive(mass) dragons are winding among the mountains” seem particularly(particular) vivid as I travel across the “roof of the world”．(P82 Para.1) 结构分析：本句为主从复合句；主句的主语是The words，系动词是seem; as引导时间状语从句，意为“当……时候”。 汉语翻译：当火车开过“世界屋脊”时，“一条条巨龙翻山越岭”的歌词变得更加生动鲜活起来。 3．I was one of the people who came from all parts of China to work(work) on this railway.(P83 Para.2) 结构分析：本句为主从复合句；who引导定语从句，修饰先行词people。 汉语翻译：修建青藏铁路的工人来自全国各地，而我就是其中之一。 4．The first landmark to catch(catch) my eye is the splendid Qingshuihe Bridge，the world’s longest bridge built(build) over permafrost.(P83 Para.3) 结构分析：本句为简单句；catch one’s eye意为“吸引某人的注意”； the world’s...permafrost是Qingshuihe Bridge的同位语。 汉语翻译：最先映入我眼帘的地标性建筑是壮观的清水河大桥，它是世界上最长的高原冻土铁路桥。 5．To prevent damage to wetlands and grasslands,675 bridges with a total length(long) of about 160 kilometres were built between Golmud and Lhasa.(P83 Para.4) 结构分析：本句为简单句；To prevent damage...是不定式作目的状语。 汉语翻译：为了避免破坏湿地和草原，我们在格尔木和拉萨之间建造了675座大桥，总长度约160千米。 6．The journey has been flying by，and before I know it，we have reached(reach) Tanggula Station.(P83 Para.5) 结构分析：本句为并列复合句；and连接前后两个并列分句；第二个分句中含有before引导的时间状语从句，before意为“还没来得及”。 汉语翻译：火车一路疾驰，还没等我反应过来，就已经到达了唐古拉车站。 7．Using thousands and thousands of sandbags，we built a twenty-kilometre wall along the lake to protect it from construction waste.(P84 Para.6) 结构分析：本句为简单句；Using thousands...sandbags为现在分词短语作状语。 汉语翻译：沿着湖边，我们用成千上万个沙袋筑起了一道二十千米的保护墙，使它免受建筑废料的污染。 8．Water birds playing in the lake，and cattle and sheep wandering(wander) the grasslands bring the scenery to life.(P84 Para.6) 结构分析：本句为简单句；主语是Water birds...and cattle and sheep...，谓语动词是bring...to life，意为“使……充满生机”；playing in the lake是现在分词短语作定语，修饰Water birds。 汉语翻译：在湖面上嬉戏的水鸟，在草原上游荡的牛羊，让这片风景充满勃勃生机。 9．I am proud that we built our “impossible” railway，and did so with the care that the environment deserves.(P84 Para.7) 结构分析：本句为主从复合句；第一个that引导宾语从句，从句的谓语动词是built和did；that the environment deserves是that引导的定语从句，修饰先行词care。 汉语翻译：我们建成了一条“不可能建成”的铁路，并且给予当地环境充分的保护，我为此感到骄傲和自豪。 Ⅱ.研典句　学用法 特殊疑问词＋不定式 How to protect the delicate ecosystem was among the top concerns.(P83 Para.2) 怎样保护脆弱的生态系统是最令人关注的问题。 结构分析：此处为“疑问词＋不定式”结构作主语； among the top concerns意为“最重要的事情之一”。 •“疑问词＋不定式”结构在句中可作主语、宾语、表语、同位语等成分。 •在“疑问词＋不定式”结构中，不定式必须用主动式，不能用被动式。 (1)问题是如何在不破坏环境的情况下发展经济。 The problem is how to develop economy without disturbing the environment.

Ⅱ.阅读理解(共4题；每小题2.5分，共10分) Victoria Falls is one of the Seven Natural Wonders of the World.Statistically speaking，it is the largest waterfall in the world.Victoria Falls is located on the border between Zambia and Zimbabwe.The falls are also close to the border of Botswana.The Zambezi River，which originates in northern Zambia，serves as the falls’ water source. There are basically two seasons for the Victoria Falls area.The rainy season runs from late November to early April with the remaining months accounting for the dry season.One would imagine that the rainy season with more water would make the falls more spectacular(壮观的)．However，the additional water and subsequent mist(水汽) in the air makes it nearly impossible to see the base of the falls. The months of June and July are probably the best time to view the falls.The water levels are still high enough to show the beauty of the falls，but the amount of water is less，creating less mist and more visibility of the falls. As you move into the later part of the dry season，August through October，it is quite possible that you will see more rock face than falls.However，this also opens the door for walking across the top of the falls，which can be a unique and exhilarating experience as well. During the rainy season and high water，Victoria Falls can be a challenge to capture(抓拍) with a camera because of all of the mist in the air.However，this increases the probabilities that you will be able to capture rainbow images around the falls. The lower water levels can create more dramatic pictures with various rocks cropping out between the falls.You should also be able to see the canyon and base of the falls.You will also be able to walk across the top of the falls and take images down the face of the falls. 1．Where does the water source of Victoria Falls originate? A．In northern Zambia. B．In southern Zimbabwe. C．At the border of Botswana. D．Between the border of Zambia and Zimbabwe. 答案　A 解析　细节理解题。根据第一段中“The Zambezi River，which originates in northern Zambia，serves as the falls’ water source.”可知，维多利亚瀑布的水源源自赞比亚北部。故选A。 2．When is the best time for travelers to walk across the top of the falls? A．From November to April. B．From August to October. C．In the months of June and July. D．In the months of May and June. 答案　B 解析　细节理解题。根据第四段“As you move into the later part of the dry season，August through October...for walking across the top of the falls，which can be a unique and exhilarating experience as well.”可知，8月到10月是步行穿过瀑布顶部的最佳时间。故选B。 3．What does the underlined word “this” in paragraph 5 probably refer to? A．A camera. B．High water. C．The rainy season. D．All of the mist in the air. 答案　D 解析　代词指代题。根据画线词上文“During the rainy season and high water，Victoria Falls can be a challenge to capture(抓拍) with a camera because of all of the mist in the air.”及下文“increases the probabilities that you will be able to capture rainbow images around the falls”可推知，空气中所有的雾虽然导致难以抓拍瀑布，却增加了你在瀑布周围捕捉到彩虹图像的可能性。故此处 this 指代的是“空气中所有的雾”。故选D。 4．What are the last two paragraphs mainly about? A．Travel strategies at different water levels. B．Challenges for falls travelers to overcome. C．Photo opportunities in different seasons. D．Different views of the falls all the year round. 答案　C 解析　段落大意题。根据倒数第二段“During the rainy season and high water...capture rainbow images around the falls.”以及最后一段“The lower water levels can create more dramatic pictures...take images down the face of the falls.”可知，文章最后两段主要讲述了在雨季与旱季旅行者的一些拍照机会。故选C。 Ⅲ.完形填空(共15题；每小题1分，共15分) When I was a child，I loved skateboarding.It brought me endless 1 .But after graduating from college and entering the workforce，the pressures of my job gradually led me to 2 this pastime.Several years later，while walking around in a park，I 3 a group of children skateboarding.It was like a clear 4 of my own childhood passion.

If successful，Kazakhstan will be the first to bring wild tigers back to a region after half a century.Only reintroduction projects within national borders and current tiger habitats have been achieved.Kazakhstan’s program is unique and urgently requires restoring a vast forest part of the wild tiger’s historical range. Since the beginning of the 20th century，wild tigers have lost over 90 per cent of their historical range.Wild tigers have completely disappeared from the region since the late 1940s，due to the loss of habitat.To prepare for the return of wild tigers，Kazakhstan will set up a new nature reserve in the southwestern Ili-Balkhash，in order to restore the unique forest habitat.This will include the protection of existing wildlife，and reintroducing important prey(猎物)，such as the endangered wild Bactrian deer(中亚红鹿)． Restoring tigers will also help protect Lake Balkhash and prevent it from repeating the fate of the Aral Sea，formerly the world’s fourth largest lake and now 10 percent of its original size.“The hard work remains ahead of us.We have to spare no effort to make this region ready for tigers and involve all the relevant people to make this happen.That means dealing with illegal activities，having these people who govern parks be well-trained and equipped，increasing prey populations and involving local communities，” said Ekaterina Vorobyeva，Director of the WWF program. 1．What is Askar Myrzakhmetov’s attitude toward the tiger reintroduction program?

D．Disapproving. 答案　B 解析　观点态度题。由第一段中的“It will not only bring wild tigers back to their original home，but also protect the unique ecosystem of the Ili-Balkhash region”可以推断，Askar Myrzakhmetov对重新引进老虎的项目是支持的。故选B。 2．What made the wild tigers disappear in the Ili-Balkhash region? A．The increasing loss of prey. B．The evolution of the species. C．The lack of natural living places. D．The serious environmental pollution. 答案　C 解析　细节理解题。由第三段中的“Wild tigers have completely disappeared from the region since the late 1940s，due to the loss of habitat.”可知，19世纪40年代末野生老虎在此区域完全消失是由于栖息地的丧失。故选C。 3．Which measure may be taken for the reintroduction of tigers? A．Regulating human activities. B．Limiting the number of prey. C．Building a reserve for tigers only. D．Training tigers to be more adaptable. 答案　A 解析　推理判断题。由最后一段中的“We have to spare no effort to make this region ready for tigers...That means dealing with illegal activities...”可知，实施这个项目需要做很多准备工作，其中包含处理违法活动，即规范人类的活动。故选A。 4．What is the best title of the passage? A．Efforts to Restore Forests in Kazakhstan B．Bringing Tigers Back Home to Kazakhstan C．Attempts to Handle Illegal Activities Effectively D．Preventing Tigers Disappearing in Kazakhstan 答案　B 解析　标题归纳题。文章一开始就介绍了哈萨克斯坦准备重新引进野生老虎的计划，下文是对这一计划的背景、内容、意义、准备工作等方面的展开介绍。所以选项B与文章主旨一致，最适合作本文的标题。故选B。 B You might think of martial arts movies when you see people performing graceful moves down the river，all standing on a bamboo strip，but actually it is a form of intangible cultural heritage: bamboo drifting(漂流)． Over 2,000 years ago，the high-quality wood，nanmu，in Guizhou was in great demand by the royal court more than 2,000 kilometers to the north.With no better transportation，people had to stand on one log(原木) to drift down the river.Later，local people began to compete along the way and the game of wood drifting was born.In the Qing Dynasty，wood drifting became bamboo drifting because of bamboo’s lower price.Due to the skills it takes for one to master this act，bamboo drifting was included in the national intangible cultural heritage list in 2021. Yang Liu，a 24-year-old inheritor of bamboo drifting，learned it at 7.“Usually，the bamboo under your feet is about 9 meters long，and the bamboo in your hands is about 5 meters.If the length or diameter(直径) of the bamboo is not long enough，it will not float.Keeping our feet firmly positioned on the narrow bamboo pole is the key，so we should fight against the current by constantly changing the angle.I lost my balance and fell in the water many times while practicing.Once I fell，I gave it another try until I knew how to handle the most difficult part，” she said. The love for the ancient skill keeps Yang going.In the past 17 years，she has drifted all year round，in winter cold and summer heat.As hanfu culture has been on the rise，Yang started wearing hanfu while performing，creating a more beautiful feel.In 2020，Yang began to post her videos on social media.“I’m extremely proud to get responses from viewers that bamboo drifting makes the line between what is possible and impossible unclear.It’s my mission to keep it alive and known to more people，” Yang Liu told China Daily. 语篇解读　本文是一篇说明文。文章主要介绍了国家级非物质文化遗产——独竹漂这项古老艺术的历史，并从其传承人杨柳的角度说明了其涉及的技艺、传承与创新。 5．What can be learned from the first two paragraphs? A．The martial arts movie is a form of cultural heritage. B．Nanmu was delivered to the north by land. C．Bamboo was costly in Guizhou 2,000 years ago. D．Bamboo drifting involves lots of skills. 答案　D 解析　细节理解题。根据第二段中的“Due to the skills it takes for one to master this act，bamboo drifting was included in the national intangible cultural heritage list in 2021.”可知，独竹漂需要很多技巧。故选D。 6．What is the biggest challenge in bamboo drifting? A．Finding the proper bamboo. B．Holding the bamboo firmly in hands. C．Maintaining a fixed angle. D．Keeping balance. 答案　D 解析　推理判断题。根据第三段中的“Keeping our feet firmly positioned on the narrow bamboo pole is the key...I gave it another try until I knew how to handle the most difficult part”可知，独竹漂的关键是能牢牢地站在狭窄的竹竿上，因为人很容易就会失去平衡而掉下去。由此可知，独竹漂的最大挑战是保持平衡。故选D。 7．What do the viewers think of bamboo drifting? A．Unbelievable. B．Elegant. C．Confusing. D．Complicated. 答案　A 解析　观点态度题。根据最后一段中的“I’m extremely proud to get responses from viewers that bamboo drifting makes the line between what is possible and impossible unclear.”可知，观众认为独竹漂模糊了可能和不可能之间的界限。由此推知，他们认为独竹漂是令人难以置信的。故选A。 8．Which of the following is a suitable title for the text? A．Transporting Bamboo down the River B．Intangible Cultural Heritage in Guizhou C．Balancing with Grace D．Yang Liu：a Creative Performer 答案　C 解析　标题归纳题。通读全文，尤其是第一段“You might think of martial arts movies...bamboo drifting(漂流)．”可知，文章围绕独竹漂这项国家级非物质文化遗产展开，结合其传承人杨柳的经历和叙述，主要介绍了其历史、技艺、传承与创新。C项“优雅地平衡”呼应第一段中的graceful moves，突出了文中对其技艺中平衡这一点的强调，最适合作为标题。故选C。 Ⅱ.七选五(共5题；每小题2.5分，共12.5分) In a world-record effort to help save a rare sea creature，Australian scientists have released hundreds of baby seahorses into the wild.The tiny seahorses are endangered，and the scientists hope the new seahorses will help their numbers grow. Seahorses are small，thin fish with a long mouth.They’re called “seahorses” because they look a bit like horses.Even though they’re fish，seahorses aren’t great swimmers. 1 There are over 40 different kinds of seahorses.They mostly live in warm，shallow waters around the world.They are often found in coral reefs，in beds of seagrass，and areas where rivers empty into the sea. 2 They eat tiny sea creatures and are eaten by bigger sea animals，such as crabs. Many kinds of seahorses are threatened，often by the actions of humans. 3 They are also sometimes caught by accident when boats are trying to catch other fish. 4 Males have a special pouch(育儿袋) that allows them to carry over 100 babies at a time.The tiny babies are born alive and can swim right away.When they’re born，the babies are about the size of a grain of rice. This is the fifth time the scientists have released seahorses into the area，and this is a new record. 5 The researchers say about 90% of them survived，which is unusually high.The researchers put tiny tags under the skin of many of the seahorses to help track them in the future.
