35.B主旨大意题。文章首段指出2021年的森林大火产生了21世纪以来最多的碳排放，然后在下文第三段、第四段对此进行进一步说明，由此推断文章主要介绍的是2021年北方森林大火造成的影响。本文是一篇说明文。文章主要介绍了一些在生活中要养成的好惯，比如爬楼梯、多喝水以及早点休息等。36.A前句是建议人们爬楼梯，后句是让人们反复上下楼梯，增加运动强度，由此推断A选项“但不要止步于此”内容适合语境，可以承接上下文。37.G前句介绍喝水有很多好处，而G选项“它有助于保持你的正常体温和排出体内的废物”则是介绍具体的好处，因此判断G项内容可以承接上文。38.D后句提到良好的姿势还能防止背痛，根据“Not only that”判断设空处应该介绍了良好姿势的其他好处，因此D选项“良好的姿势可以减轻压力”内容适合语境。干扰项F能够承接上文但是和后句不能构成内容的衔接。39.C本段介绍了睡眠的好处并建议人们早点睡觉，因此判断C选项“提前半小时上床睡觉”可以作为本段主题句。B选项“改变你的坏睡眠惯”为干扰选项，本段没有涉及坏的睡眠惯，因此不能概括本段中心。40.E空前提到要专注于自己的目标，因此判断E选项“如果你偏离了目标，那就重新开始”可以承接上文。本文是一篇记叙文。文章主要讲述了作者因为论文中的数据引用错误最终决定撤回论文的一段经历，本着对科学严谨、开放的精神，作者接受了评论家的意见，承认了自己的错误，做出了他认为正确的选择。41.B考查动词。根据文章首句以及破折号后的内容可知，作者和导师没有时间多聊因为飞机马上就起飞了。42.A考查名词。根据破折号后面的“disbelief,embarrassment and frustration”可知，作者心情复杂，内心各种情感都有。43.C考查名词。根据后句中“Nature sent our response out'”可知，作者草拟了一份回复文件来纠正数据错误并为自己的方法进行辩护。44.C考查动词。解析同上。45.A考查名词。根据后句中的“reviewers'”可知，《自然》杂志将作者的回应发给了别人进行评议。review“仔细研究，审视”。46.D考查动词。根据后面的“Colleagues”以及下文“Ioffered my resignation(辞职信)tomydepartment head'”可知，作者已经有一份工作，secure意为“获得，得到”。47.B考查动词。同事劝作者不要理会社交媒体上的评论。48.A考查副词。根据语境可知，作者因为论文中的错误，在撤回论文后，正式向部门主管递交了辞职信。49.D考查动词。根据主管说的话可知，部门主管没有接受作者的辞职。50.B考查名词。根据句中的“mistakes”以及首段出现的“wrong data”可知，主管认为作者论文中的错误不是欺骗性质的，是无心之过。此处“honest mistakes”指“无心之过”。51.C考查动词短语。作者写了辞职信，但是在部门主管的开导下作者想坚持继续做下去，carry on意为“继续”。52.D考查名词。作者因为论文中的错误而受到了人们的质疑，因此他想赢回自己的声誉。53.B考查形容词。根据后文内容可知，因为之前的错误，作者此后发表论文、得到新项目的资助基金都很难，因此判断他想赢回自己声誉的道路是艰难的。54.D考查形容词。解析同上。55.A考查形容词。根据语境以及转折词“but”可知，作者认为虽然这件事让自己很羞愧，但他做了正确的事情。本文是一篇说明文。在看到大熊猫丫丫糟糕的状态后，在海外的中国人纷纷拍摄大熊猫在各国的生活状况的视频，以此呼吁人们要重视大熊猫的生活状况。56.innocent考查形容词。设空处在句中修饰名词pandas且和cute作并列定语，故判断填形容词innocent。57.respectively考查副词。设空处修饰动词visited,应该用副词作状语。58.eating考查非谓语动词。根据句意可知，设空处在句中说明a panda的动作，故用现在分词eating表示主动关系。59.inspected考查非谓语动词。设空处在句中作后置定语修饰名词zoos,故填过去分词。60.recognition考查名词。空前是名词所有格，因此设空处应该填名词，因为recognition是不可数名词，故填recognition。英语第4页（共7页）
