Similar to the tug-of-war（拔河），this sport requires players to tie a rope around their waist（腰部）and crawl（爬行） forward. Evolving from traditional grassland entertainment， the nomadic （游牧的） culture has been passed down to younger generations.In Lapaniu，the one-to-one format has extended （延伸） to a team battle and the length of rope has been shortened based on the height of primary school students. Teachers have also tied the soft pads used in other traditional sports in case the students get hurt.“The traditional sport that can be played anywhere and with simple equipment has become popular among young people, lighting up their summer life on the grasslands in remote mountain areas,” said Wang Fugui，deputy director（副校长） of a primary school in Sunan Yugur Autonomous County of Gansu.“The traditional sporting culture of ethnic groups is an important part of China's cultural heritage, playing an active role in improving physical and mental health as well as in strengthening friendship between one another,” said Wang答案解析【A完形填空】1．B．考查动词辨析。A项意为“抓住”，B项意为“出生”，C项意为“拿；携带”，D项意为“说话”。空格所在部分意为“今年上半年          小鹿数量为196头”，上一句提到麋鹿数量不断增加。由此可知，“出生的小鹿数量”符合文意，故选B。2．A。考查动词辨析。A项意为“不断”，B项意为“停止”，C项意为“知道”，D项意为“攀登”。空格所在部分意为“湖北省石首市石首麇鹿国家级自然保护区在         寻找湿地保护和麋鹿疾病预防的解决方案”，将选项代入句中，只有A项符合文意，故选A。3．C。考查主语从句。根据句子结构可知，空格处所填词与后面的 we fear the most一起作主语，is是系动词，an animal epidemic是表语。很显然，空格处需填入一个能引导主语从句的词，what在主语从句中作fear的宾语，符合文意及要求，故选C。4．A。考查动词辨析。A项意为“死亡”，B项意为“生存”，C项意为“行走”，D项意为“奔跑”。根据空格后的as the result of an epidemic in 2010（由于2010年的一场 流行病）可知，空格所在部分描述的是这场流行病给麋鹿带来的影响，流行病带来的肯定是消极影响。将四个选项分别代入文中，只有A项符合文意，故选A。5．D。考查形容词辨析。A项意为“不同的”，B项意为“美丽的”，C项意为“容易的”，D项意为“困难的”。根据空格后面的内容“疫情变得更加严重，而且我们缺乏足够的专业人员和检测方法”可知，manage the health of the deer（麇鹿的健康管理）这件事是越来越困难的，将各选项代入句中，只有D项符合文意，故选D。6．A。考查连词辨析。空格前的句意为“麋鹿的健康管理变得越来越困难”，空格后的句意为“疫情变得更加严重，而且我们缺乏足够的专业人员和检测方法”，由此可判断空格前后为因果关系，前面是果，后面是因，所以应该填入表示“因为”的连词，只有A项符合，故选A。7．C。考查动词辨析。A项意为“承诺”，B项意为“移动”，C项意为“提供”，D项意为“管理”。空格所在部分意为“为了给数量不断增加的麇鹿和鸟类          足够的空间”。根据下文提到的“需要更大的栖息地”可知, C项符合文意，故选C。8．B。考查名词辨析。A项意为“光线”，B项意为“食物”，C项意为“热源”，D项意为“能量”。空格所在句意为“为了给数量不断增加的麇鹿和鸟类提供足够的空间，保护区需要更大的栖息地和更多的         来源”。根据句意可知，麋鹿和鸟类不断增多，那么肯定是需要更多的食物。故选B。9．A。考查动词辨析。A项意为“增加”，B项意为“减缓”，C项意为“阻止”，D项意为“切；割”。空格后指出 About 30 left the reserve in 1998 and now they number around 1,000（1998年，大约有30头麋鹿离开了保护区，现在它们的数量大约增加到了1000头），空格所在句描述的是麋鹿的数量，由此可知，麋鹿的数量从1998年的大约30头增加到了现在的1000头。故选A。10．D。考查动词辨析。A项意为“吃”，B项意为“射击”，C项意为“避免”，D项意为“打扰”。空格所在句意为“我们每年对它们的活动和栖息地监测两次，不会           它们”。根据全文大意可知，麋鹿是濒危动物，会受到国家保护，所以不可能是“吃”或“射击”麋鹿。“避免”代入文中后语义不当，故排；只有“打扰”符合文意，故选D。【B阅读理解】1．C。细节理解题。根据题干关键词 ecosystem of the Yellow River定位到第一段，根据该段中的 Shaanxi Province has made every effort to protect the ecosystem of the Yellow River...through legislation（陕西省已加大力度，通过立法保护黄河生态系统··..·）可知，陕西省是通过立法来保护黄河生态系统的，所以C项符合文章内容，故选C。2．D。细节理解题。根据题干关键词32 local regulations定位到第二段，该段列举了32项地方性法规涵盖的多个方面，即 ecological restoration， watercourse management， soil and water conservation, pollution control, high-quality development and cultural protection。对比四个选项和文章 内容可知，D项 Low-quality development与文中的high-quality development相悖，故选D。3．C。细节理解题。第一段指出，陕西省已加大力度，通过立法保护黄河生态系统。A项“陕西省并不关心黄河的生态系统”与文意相悖，故排除；全文都在讲述陕西省在保护黄河生态系统方面做出的努力，B项“陕西省在保护环境方面做得很少”明显与文意不符，故排除；D项“陕西省的环境非常差”在文中未提及，属无中生有，故排除。浏览全文可知，陕西省在保护黄河生态系统方面做出了努力，C项“陕西省已经采取了一些措施来保护黄河”符合文意，故选C。4．A。细节理解题。根据第三段第二句中的the Qinlig Mountains, the natural boundary between northern and southern China可知，中国南北地区的自然分界线是秦岭，故选A。5．B。细节理解题。根据第四段中的 the Weihe River，the largest branch of the Yellow River可知，黄河的最大支流是渭河，故选B。【C阅读理解】1．B。细节理解题。第一段第一句指出 In recent years，with China's ecological protection and anti-poaching efforts, the population of Tibetan antelopes has increased（近年来， 因为中国在生态保护和反偷猎上的努力，藏羚羊的数量增加了）。由此可知，藏羚羊的数量增加是因为中国在生态保护和反偷猎上的努力。B项是对原文的原词复现，其余选项均与原文不符，故选B。2．C。词义猜测题。画线单词前是 a recent statement（最近的一份声明），画线单词后是 by the National Forestry and Grassland Administration（国家林业和草原局），画线单词的意思要能够恰当地描述这两者的关系，只有C项符合，代人文中表示“国家林业和草原局最近发布的一份声明”，故选C。3．C。细节理解题。第二段第一句指出 Tibetan antelopes are mostly found in the plateau region of northwest China, including the Tibet Autonomous Region, Qinghai Province and the Xinjiang Uygur Autonomous Region（藏羚羊主要 分布在中国西北部的高原地区，包括西藏自治区、青海省和新疆维吾尔自治区）。四个选项中只有C项“新疆维吾尔自治区”在文中被提及，其余三项均未被提及，故选C。4．A。细节理解题。第四段第一句指出 In Qinghai Province，Tibetan antelopes mostly live in the Hoh Xil National Nature Reserve in Sanjiangyuan National Park（在青海省，藏羚羊主要生活在三江源国家公园的可可西里国家级自然保护区）。A项是原文的原词复现，故选A。5．D。推理判断题。最后一段的引语指出Qinghai Provincebegan its anti-poaching and protection work in the 1990s （青海省早在20世纪90年代就开始了反偷猎和保护工作）。故A项“青海省不关心藏羚羊”和C项“青海省还没有开展反偷猎和保护工作”可排除；B项“再也没有人偷猎藏羚羊了”过于绝对，且无法从最后一段推断得出，故排除；D项“青海省为保护藏羚羊做出了努力”符合文意，最后一段主要描述的就是青海省为保护藏羚羊做出的努力，故选D。【D阅读理解】1．E。本题意为“五里坡国家级自然保护区已成为一项世界遗产，这将使我们能够采取更多措施来保护濒危物种，维护重庆东北部生态系统的完整性”。浏览右栏的七个选项，只有E项提到了 wild terrestrial vertebrate species、endangered animal species 和 species of seed plants，这些都是能够出现在自然保护区的生物，故选E。2．A。本题意为“由于全球变暖，青藏高原的冰川近年来一直在缩小”。很明显，A项中的 the water tower of Asia（亚洲水塔）就是形容青藏高原的，且根据后面的glaciers（冰川）、water resources（水资源）也能确定A项与本题对应，故选A。3．B。本题意为“山丹境内的长城位于中国西北部甘肃省广阔的戈壁沙漠深处”。B项意为“不像北京著名的八达岭长城，它是用夯土建成的”。B项中的Badaling Great Wall与the Great Wall对应，故选B。4．F。本题意为“以＇马＇为主题的乐园-中国马镇，建立在广阔的草原上”。F项中提到了the town 和 horse elements，且根据句意“这座小镇位于河北省，有5个新剧院，游客可以欣赏以“丝绸之路＇和“马＇元素为特色的表演”也可推测出，F项描述的是马镇，故选F。5．C。本题意为“喀什是中国最西端的城市。晚上10点之前，甚至更晚的时候，这里的天都不会黑”。C项提到enjoys up to 18 hours of sunshine during the summer（夏 天的日照时间长达18小时），与题干中的“晚上10点之前，甚至更晚的时候，这里的天都不会黑”相对应，由此可知，C项与题干描述的地点相符，故选C. 【E 任务型阅读】1． Glossy ibis is a kind of bird．根据第一段第一句中的Glossy ibis， an elegant and colorful bird（彩鹮-一种姿 态优雅且色彩斑斓的鸟类）可知，彩鹮是一种鸟类动物。2.Their feathers will flash different colors with the change of light angle.第一段第二句指出 Their feathers will flash different colors with the change of light angle（它们的羽 毛会随着光线角度的变化而呈现不同的颜色）。题干问的是彩鹮羽毛的特点，本句正好回答了这个问题。3.Because glossy ibises are rare. 根据第二段第二句They are called “panda of birds” because they are rare（因其稀 有而被称为“鸟中大熊猫”）可得出答案。4。Seven．根据第三段第二句 In 2020， Chen saw seven of the ibises at the base， five from the same family（2020年，陈 德智在基地观察到了7只彩鹮，其中5只来自同一家庭）可得出答案。5.We could throw the rubbish into dustbin and use plastic bags as less as possible.本题为开放题，回答言之有理即可。【F短文填空】（1）countries。空格后指出了具体的国家名称，如中国、越南、泰国和缅甸等。由此可知，空格处是一个概括性的名词，表示“国家”，故填 countries。（2）lives。根据句子结构可知，本句缺少谓语，主语是Amore special but little-known species，结合上一句中的 The blue peafowl mainly lives in India 可知，本句应该 也是同样的表达，故空格处应填人动词live，又因主语为第三人称单数，故填lives。（3）are。根据句子结构可知，本句为there be句型，后面的名词为复数，且前半句的谓语时态为一般现在时，故填are。（4）to。根据句子结构可知，空格所在部分为状语，且根据句意“从孔雀织锦和古代壁画，         用孔雀羽毛制成的皇家扇子，美丽的绿孔雀在中国传统文化中是好运和高贵的象征”可知，此处应表达“从··到···..”的意思，from...to...结构符合此意，故填to。（5）green。本段第一句指出“美丽的绿孔雀在中国传统文化中是好运和高贵的象征”，空格所在句意为“在清朝，只有高级官员才被允许戴饰有          孔雀羽毛的帽子”。由此可推断，空格处讲的也是“绿孔雀”，故填 green。（6）because。空格前指出“云南省的傣族人民称这种鸟为“金孔雀＇”，空格后指出“根据光线的角度，它们的羽毛会从绿色变成蓝色、铜色和金色”。由此可知，空格前后内容在逻辑上为因果关系，且前为果，后为因，故填 because。（7）was。根据句子结构可知，本句的谓语动词是listed，而主语 the green peafowl和listed为被动关系，故需要在listed前加一个be动词，构成被动语态，又根据前面的时间状语In2009可知，本句应用一般过去时，且 green peafowl为一个整体，谓语动词用单数，故填was。（8）In。根据句子结构可知，空格处是时间状语，2007为年份，故填介词In。（9）eats。空格所在句意为“孔雀          昆虫、小动物和植物”。该句缺少谓语，需要填入一个谓语动词，结合常识可知，此处讲的应该是孔雀吃昆虫、小动物和植物，故填eats。（10）and。该句包含一个if引导的条件状语从句，abandon their nests和run away为两个并列的动作，故填并列连词and.
