【知识点】目的意图、逻辑推理、语意转化、记叙文、故事
【分析】这是一篇记叙文。文章讲述了某一天孙子问爷爷读书的作用是什么，爷爷便让孙子拿着一个脏篮子去河里带回一篮子水，孙子照做了，但在他回到房子前，水已经全没了。孙子又如此反复了一次，最后发现脏篮子变成了干净的篮子。爷爷通过这件事想告诉孙子我们可能不会记住所有的事情，但当我们坚持阅读时，我们的内在和外在都将会改变。

25.词句猜测题。根据画线前的“His grandsn wanted t be just like his grandfather,…”可知孙子想成为像他爷爷一样的人。由此可推断出emulate 就是be just like，即cpy（模仿）。故选A项。
26．推理判断题。根据倒数第二段“The by lked at the basket and fr the first time he realized that the basket was different. It had been changed frm a dirty basket t a clean ne.(男孩看着篮子，第一次意识到篮子不同了。它从一个脏篮子变成了一个干净的篮子)”可知，爷爷通过让孙子一遍遍用篮子去河里提水回来，以此来向孙子说明读书的作用，由此可推知，这位爷爷很聪明。故选D。

【来源】安徽省阜阳市临泉田家炳实验中学2023-2024学年高一上学期期中考试英语试卷
【知识点】文化保护、中国文化与节日、说明文
【导语】这是一篇说明文。文章向读者介绍了中国传统的表演艺术——舞狮。
28．细节理解题。根据第三段“There are 21 ples which are 1.2meters-2.5 meters high.The distance between tw ples is up t 1.8 meters. (有21根高度在1.2米到2.5米之间的柱子，它们之间的距离高达1.8米)”可知，舞狮中用到的柱子之间距离最远达1.8米。故选A项。
29．细节理解题。根据倒数第二段“As a result, the ancient art frm has fallen ut f favr with the yung generatin, as the skills take years t master while nly a lw wage can be earned. Als, caches and funding can be hard t find, s it’s difficult fr a lin dance trupe (表演队) t survive.(因此，这种古老的艺术形式已经失去了年轻一代的青睐，因为掌握这些技能需要多年的时间，而工资却很低。此外，教练和资金很难找到，所以舞狮团很难生存)”可知，舞狮表演队很难生存其中一个原因就是薪水很低。故选C项。
30．推理判断题。根据倒数第二段末句“But since 2017, lcal authrities in Guangxi have teamed up with cmpanies and schls t help rebt the ancient art.(但自2017年以来，广西地方当局与公司和学校合作，帮助重启这门古老的艺术)”可推测，当地政府很重视这种艺术的传承。故选B项。
31．主旨大意题。第一段“The lin dance is ften perfrmed in celebratins t this day and in 2006, it was listed as a natinal intangible cultural heritage.(舞狮活动至今仍是庆祝活动的一部分，2006年，舞狮被列为国家非物质文化遗产)”主要介绍了这种艺术的历史悠久及其在中国文化中的地位；第二段至第四段介绍了这种古老的艺术形式的动人之处及其现在的状况，学习和训练危险又辛苦，也不能短时间学成，收入却很少，很少年轻人愿意学习，有失传的风险，而这是中国文化的重要组成部分，不能失传，最后两段讲述了政府和舞狮爱好者在不断努力使这种古老艺术传承下去，焕发新的生机。所以综合全文，这篇文章旨在介绍使舞狮文化生存下去的重要性，三个选项只是文章中的几个细节，不是文章主旨。故选D项。
32．C 33．A 34．B 35．B
【导语】本文是一篇说明文。本文主要介绍了青少年的健康问题，并且针对不同的青少年的健康问题，给出了一些具体的运动方案。
32．推理判断题。根据第二段中的““Inactive” means that the persn des nt jin in many physical activities, but is nt seriusly verweight.(“不活跃”是指该人不参加许多体育活动，但不是严重超重。)”可知，不活跃指的是不经常参加体育锻炼，但不是过度肥胖，由此可以判断，不活跃的青少年不是严重肥胖。故选C项。
33．细节理解题。根据第一段中的“It reduces stress and imprves fitness. Exercise makes yur bdy strng, and helps yu t keep the right bdy weight.(它可以减轻压力并改善健康。运动使你的身体强壮，并帮助你保持正确的体重。)”可知，锻炼能让青少年更健康，B选项正确；根据第三段中的“Ride a bike, play vlleyball r basketball fr a while，and g fr a twenty­minute walk each day. All these will help t burn calries.(骑自行车，打排球或篮球一会儿，每天散步二十分钟。所有这些都将有助于燃烧卡路里。)”可知，锻炼能够燃烧热量，故C项正确；根据最后一段中的“Sme weight­training and ther bdy­strengthening exercises culd als be planned in the prgramme in rder t increase the persn’s strength.(可以计划一些重量训练和其他健美运动，以增加人的力量。)”可知，锻炼能增加人的力量，D项正确；A选项在文中未提到。故选A项。
