We see hazy skies on Earth too, from time to time, whenever solid particles get suspended in the air—from water-based fogs, to ash from fires, to the toxic droplets that make up a thick smog.
地球上也会时不时出现朦胧的天空，这是因为固体颗粒悬浮在空气中——从水汽形成的雾，到火灾产生的灰烬，再到构成浓重烟雾的有毒液滴，都是如此。
"whenever" 引导完整分句 "solid particles get suspended in the air..."，表示每当固体颗粒悬浮在空气中时，主句所述现象便会出现，因此属于时间状语从句。
Your self-discipline is akin to a muscle, and each time you resist temptation or persist in a task despite a lack of motivation, you strengthen that muscle, leading to less effort and resistance in similar instances in the future.
自律就像肌肉一样：每当你抵制诱惑，或在缺乏动力的情况下仍坚持完成一项任务，你都在强化这块“肌肉”，从而让自己今后在类似情况下付出更少的努力，也更少产生抗拒感。
"each time" 是复合时间连接表达，相当于 "whenever"，引导从句 "you resist temptation or persist in a task"，整体修饰主句的 "strengthen"，说明强化自律发生在每一次抵抗诱惑或坚持任务之时。由于类型枚举中没有 "each time"，引导词归入“其他”。
It was a lazy, hazy, crazy day on the dwarf planet Pluto when New Horizons, a spacecraft from Earth, flew by at a speed of 31,000 mph (miles per hour) two years ago.
两年前，当来自地球的“新视野号”宇宙飞船以每小时 31,000 英里（mph，即英里/小时）的速度飞掠而过时，矮行星冥王星上度过了慵懒、朦胧而疯狂的一天。
该从句由"when"引导，内部有完整主语"New Horizons"和谓语"flew by"，说明主句所说的那一天发生飞掠事件的时间背景，因此是时间状语从句。
If you believe that exercising your self-control strengthens and fuels it, that is more likely to be your experience as you resist temptation or push yourself to get something done that is not appealing.
如果你相信锻炼自制力会增强并激发它，那么当你抵制诱惑，或迫使自己完成不感兴趣的事情时，你更有可能确实产生这样的体验。
"As" 在这里近似 "when/while"，引导时间状语从句，表示主句所说的体验发生在你抵抗诱惑或迫使自己完成某事的过程中。主语 "you" 后连接 "resist" 和 "push" 两个并列谓语。
Experts believe it is all about the age you learn how to spend responsibly.
专家认为，关键在于你从多大年纪开始学会理性消费。
该分句表达"在你学会如何负责任地花钱的那个年龄"中的时间关系，修饰"the age"所表示的时间点。句中省略了与"age"搭配的介词"at"，可理解为"at the age [at which/when] you learn how to spend responsibly"。它不是由关系词零引导的定语从句，也不是倒装条件句；在给定枚举中只能暂以"零引导(倒装条件)"标记其无显性引导词，但该枚举并不能准确描述此处的省略形式。
常见引导词： if 654 · unless 34 · 其他 26 · when 12 · 零引导(倒装条件) 11 · as 6
Thus, had he owned some land in Athens itself, including the land the tree sat on, presumably he would have sold it to raise funds or otherwise had it taken as well.
因此，如果他在雅典本身拥有一些土地，包括那棵树所在的土地，想必他会卖掉它来筹集资金，否则也会让它被夺走。
省略 if 的倒装条件从句,通过 "had he owned" 的倒装结构体现,表达与过去事实相反的假设条件,引导整个虚拟条件句
The average male creative arts students, indeed, apparently earn much less than they would, had they simply never gone to university.
普通男性创意艺术学生，确实，显然赚得远比他们本应赚的少，如果他们根本没有上过大学的话。
虚拟条件从句，采用倒装省略"if"的形式（"had they gone"倒装自"if they had gone"），表示与过去事实相反的假设条件"如果他们从未上过大学"。此从句为主句中的"would"提供虚拟条件，与主句中的"would earn"构成完整的虚拟语气结构。
In regularly reflecting on the things in his life he is grateful for, Defoe's Crusoe believes that he becomes a far better person than he would have been had he remained in the society from which he originally set out on his voyage.
在定期反思他生活中所感激的事物时，笛福笔下的鲁滨逊认为，他成为了一个比如果他留在他最初出发航行的那个社会中原本会成为的人要好得多的人。
"had he remained..." 是省略 if 的倒装条件句，相当于 "if he had remained in the society..."，为前面的 "he would have been" 提供虚拟条件，因此属于条件状语从句。
Had the bell towers' wooden frames burned down, the heavy bells would have crashed down.
如果钟楼的木制框架烧毁了，沉重的钟就会坠落。
这是一个省略 if 的倒装条件状语从句，表达与过去事实相反的假设条件。原形式为 "If the bell towers' wooden frames had burned down"，通过将助动词 "had" 提前至句首、省略 "if" 形成倒装结构。从句使用过去完成时 "had burned down"，符合虚拟语气条件从句的时态要求。该从句在逻辑上为主句提供假设前提。
If you don't already view self-discipline as a force that feeds itself, what might you do?
如果你还没有把自律看作一种会自我强化的力量，你会怎么做？
该分句由条件连词“If”引导，完整表达“你是否已经把自律看作一种自我强化的力量”这一条件，整体修饰主句“what might you do?”，因此属于条件状语从句。
常见引导词： while 129 · although 87 · though 86 · 其他 62 · if 29 · as 22 · when 15 · after 1
This idea has the virtue of simplicity, though some experts question its effects and call for a greater degree of differentiation, arguing that time online by itself is not a bad thing and it all depends on what you are doing.
这个想法具有简单这一优点，尽管一些专家质疑它的影响，并呼吁进行更大程度的区分，认为上网时间本身并不是一件坏事，而这一切都取决于你正在做什么。
"though"引导完整分句，对主句内容作让步补充，因此属于让步状语从句。
The character traits held for every kind of community, be they traditional hunter gatherers or advanced civilizations, helping to uphold civilized society and foster social cooperation, researchers found.
研究人员发现，为每种社区所具有的性格特征——无论是传统的狩猎采集者还是先进的文明——有助于维护文明社会和促进社会合作。
这是一个让步状语从句,相当于 "whether they be...",使用了虚拟语气倒装,省略了 whether 并将 be 提前至句首,用以表示"无论是...还是..."。
Sir Jim Smith, Director of Science at Wellcome, said, "Try as I might, I can't think of a more exciting, more relevant, more timely or more internationally inspirational project.
韦尔科姆科学总监吉姆·史密斯爵士说：“尽管我尽了最大努力，我也想不出一个更令人兴奋、更相关、更及时或更具国际启发性的项目。
"Try as I might" 是倒装式让步状语从句，相当于 "Although I might try" 或 "No matter how hard I might try"，表示“尽管我可能努力去想”。其中 "as" 引导让步意义，整个从句修饰后面的 "I can't think of..."。
According to new research from the University of Stirling in Scotland, although both men and women perceive women who wear makeup as being of a higher status, men associate makeup with prestigious, positive qualities, while women view other women wearing makeup as being dominant and a potential threat.
苏格兰斯特灵大学的一项新研究表明，尽管男性和女性都认为化妆的女性社会地位更高，但男性会将化妆与尊贵、积极的品质联系起来，而女性则认为其他化妆的女性更具支配性，可能构成威胁。
该分句由"although"引导，表示让步背景：虽然男女都认为化妆女性地位更高，但主句随后说明男性对化妆的不同联想。其内部的"who wear makeup"修饰"women"。
Whether you call it a motivator, a burning goal, or a bright idea, this idea is the force behind your willpower.
无论你把它称作动力、炽热的目标，还是绝妙的想法，这个念头都是支撑你意志力的力量。
"Whether...or..." 在这里引出让步状语从句，表示无论把它称作 "a motivator"、"a burning goal" 还是 "a bright idea"，主句结论都成立。这里的 "whether" 不是名词性从句引导词，而是让步结构的一部分；由于枚举没有单列 whether，按长尾让步连接形式归入“其他”。
But while some may struggle to pay their bills after a few too many nights out at the start of the month, others will have a tightly followed plan for their repayments.
不过，有些人在月初外出狂欢了几晚后，可能会因为花销过多而难以支付账单；而另一些人则会严格按照计划偿还款项。
该分句由"while"引导，表示有些人在月初外出过多后可能难以支付账单，与主句中的"others"形成对比。这里的"while"表示“而、与此同时”的对比关系，不是“尽管……仍然……”的让步关系。
The research showed that men and women both rated the faces with cosmetics as being more attractive, but only women rated made-up faces as being more dominant, while only men rated made-up faces as being higher in prestige.
研究表明，男性和女性都认为化妆后的面孔更具吸引力；但只有女性认为化妆后的面孔更具支配性，而只有男性认为化妆后的面孔具有更高的声望。
该从句由"while"引导，表示与女性评价相对的男性评价结果。它在意义上对比"only women rated ... more dominant"，从句内部主干为"only men rated made-up faces ..."。
Ask a man and a woman to go diving for the first time, and the woman is likely to jump in, while the man is likely to say he's not feeling too well.
让一名男性和一名女性第一次去潜水，女性可能会跳下去，而男性可能会说他感觉不太舒服。
"while" 在这里不是时间意义“当……时候”，而是表示对比，相当于 "whereas"；整个从句 "while the man is likely to say he's not feeling too well" 对照前面 "the woman is likely to jump in"，说明男性的不同反应。
Hunting "designed to secure the aggregate welfare of the target species, the integrity of its ecosystem, or both"—what Varner terms "therapeutic hunting"—is defensible, while subsistence and sport hunting—both of which only benefit human beings—are not.
旨在确保目标物种的总体福利、其生态系统的完整性或两者兼而有之的狩猎——Varner称之为“治疗性狩猎”——是合理的，而仅使人类受益的生计狩猎和娱乐性狩猎则不然。
while引导对比状语从句,与前面的主句"Hunting is defensible"形成对比关系,说明生存狩猎和运动狩猎不可辩护。从句主语"subsistence and sport hunting"后有破折号插入的非限制性定语从句"both of which only benefit human beings"修饰,谓语"are not"承前省略了表语defensible。
Less sport, and fewer meetings with peers correlated with lower wellbeing, as did less time reading print media (newspapers) and, surprisingly, less time doing homework.
更少的体育运动、更少与同伴的会面与更低的幸福感相关，正如更少阅读印刷媒体（报纸）的时间，以及令人惊讶的是，更少做家庭作业的时间也是如此。
"as"引导对比状语从句,表示"也同样如此"。使用了倒装结构"as did + 主语",助动词"did"提前代替"correlated with lower wellbeing",主语为"less time reading print media (newspapers) and less time doing homework"(两个并列的动名词短语)。此结构通过倒装和替代避免重复主句谓语,表达同样的相关性关系。
There are parts of the banking sector that will always be prone to risk, but many bankers have come to feel immune to its potential impact, because they presume that, however recklessly banks behave, governments will always be there to bail them out.
银行业中总有一些领域容易遭受风险，但许多银行家逐渐觉得自己可以免受风险潜在影响，因为他们认为，无论银行的行为多么鲁莽，政府总会出手纾困。
这是原因状语从句，由“because”引导，修饰主句“many bankers have come to feel immune...”，说明银行家产生这种感觉的原因是他们认为政府总会出手救助银行。
"But progress is being made through emerging schools, because if you teach children when they are young, it will stay with them as adults and that's the future," says Mr. Nawusky, a Comanche Indian.
"但是进步正在通过新兴学校取得，因为如果你在孩子们年幼时教他们，它会随着他们成年而保留下来，而那就是未来，"科曼奇印第安人纳乌斯基先生说。
"because" 引导原因状语从句,解释 "progress is being made" 的原因。从句内部包含条件状语 "if..." 及其内嵌的时间状语 "when...",主句部分是并列结构 "it will stay... and that's..."。
"A sleeping pill will target one area of the brain, but there's never going to be a perfect sleeping pill, because you couldn't really replicate(复制) the different chemicals moving in and out of different parts of the brain to go through the different stages of sleep," says Dr. Nancy Collop, director of the Emory University Sleep Center.
"安眠药会作用于大脑的一个区域，但永远不会有完美的安眠药，因为你无法真正复制不同化学物质在大脑不同部位进进出出以经历不同睡眠阶段的过程，"埃默里大学睡眠中心主任南希·科洛普博士说。
because 引导原因状语从句，说明前面 "there's never going to be a perfect sleeping pill" 的原因。从句主语 you（泛指），谓语 couldn't replicate，宾语是 "the different chemicals moving…"。
Psychologists call these specific plans implementation intentions because they state when, where, and how you intend to implement a particular behavior.
心理学家将这些具体的计划称为“执行意图”，因为它们明确说明了你打算在何时、何地以及如何实施某一特定行为。
“because”引导原因状语从句，完整内容为“they state...”，说明心理学家称这些计划为“implementation intentions”的原因。该从句内部的“when, where, and how...”又整体充当“state”的内容宾语。
"I truly believe that it makes me a more sensible human being, as I tend to see and appreciate the creative solutions people come up with in other parts of the world, even though many tend to have far more constraints than we have at home."
我真的相信，这让我成为一个更加明智、通情达理的人，因为我总能看到并欣赏世界其他地方的人们想出的富有创意的解决方案，尽管他们中的许多人所受到的限制往往比我们在本国面临的多得多。
该从句由 as 引导，在此表示“因为/由于”，作为 that 宾语从句内部的原因状语，说明说话者为何认为相关经历使自己更理性。其内部包含修饰 solutions 的零引导限制性定语从句；句末 even though 成分的附着范围存在歧义，不能据此稳定地把它判作本从句的子从句。

The Harvard psychologist Steven Pinker put it this way, "People are embraced or condemned according to their beliefs, so one function of the mind may be to hold beliefs that bring the belief-holder the greatest number of allies, protectors, or disciples(信徒), rather than beliefs that are most likely to be true."
哈佛大学心理学家史蒂芬·平克这样说：“人们根据他们的信仰被接纳或谴责，因此大脑的一个功能可能是持有给信仰持有者带来最多盟友、保护者或信徒的信仰，而不是最有可能是真实的信仰。”
由 "so" 引导的结果状语从句，说明前述现象的推论。从句主语 "one function of the mind"，系动词 "may be"，表语为不定式短语 "to hold beliefs..."，后接两个并列的定语从句分别修饰 "beliefs"，由 "rather than" 连接形成对比。
Such people are so afraid of being labeled a failure at anything that they constantly develop one handicap or another in order to explain away failure.
这类人非常害怕在任何事情上被贴上失败的标签，以至于他们不断地制造这样或那样的障碍，以便为失败辩解。
该分句由"that"引导，与主句中的程度副词"so"前后呼应，构成"so...that"结果状语从句，说明"害怕被贴上失败标签"这种程度所导致的结果——即"they constantly develop one handicap or another in order to explain away failure"。由于此处的"that"并非固定短语"so that"，而是与"so"分离呼应的关联词，故引导词标记为"其他"。从句内部含有目的不定式短语"in order to explain away failure"修饰谓语"develop"，但该短语无主谓结构，不构成独立分句，因此不再向下递归拆分。
"America educates so many more people at university that one can't expect all those who go to be as intelligent as the much narrower band in British universities," says Prof. Christopher Ricks at Boston University.
“美国在大学里培养了如此多的人，以至于不能期望所有上大学的人都和英国大学里范围窄得多的群体一样聪明，”波士顿大学的克里斯托弗·里克斯教授说。
that 引导的结果状语从句，表示主句 "America educates so many more people at university" 导致的结果。从句主干为 one can't expect all those…to be as intelligent as…，含复杂宾语结构。
She said the aim was to really make sure that the transition from the driver to the vehicle is done in a safe way, so we can take into consideration the driver's state, and so we do not give control to a driver who is under pressure of fatigue, stress, anxiety, and so on.
她表示，这样做的目的是确保驾驶员将控制权交还给车辆的过程真正安全可靠。这样一来，我们就能考虑驾驶员当时的状态，避免将控制权交给处于疲劳、压力、焦虑等状态下的驾驶员。
该分句与前面的“so we can...”构成并列的结果表达，说明因此不会把控制权交给处于疲劳、压力或焦虑影响下的驾驶员。这里的“and”连接结果分句，“so”表示结果而非目的。
A bit cynically, Bass describes colleagues who never published because they waited so long they became ill or died.
略带讽刺地，巴斯描述了那些从未发表过作品的同事，因为他们等了太久，以至于生病或去世了。
结果状语从句,由"so...that"结构引导(that省略)。前面的"so long"表示程度,本从句"they became ill or died"表示等待时间过长导致的结果。这是与原因从句平级的结果从句,共同说明定语从句的情况。
常见引导词： so that 41 · 其他 12
The first hour, he claimed, was necessary for misperceptions to be eliminated.
他声称，第一个小时对于消除误解是必要的。
"for misperceptions to be eliminated" 是 for-to 不定式结构,说明 "was necessary" 的目的,即为了消除误解。"for" 引入逻辑主语 "misperceptions","to be eliminated" 是被动不定式作谓语,整体作目的状语从句。
To offset this bias, deliberately refocus your thinking on the gains so you can more objectively weigh the alternatives.
为了抵消这种偏见，故意将你的思维重新聚焦于收益，以便你能更客观地权衡这些选择。
"so you can more objectively weigh the alternatives" 由 "so" 引出，说明主句动作 "refocus your thinking on the gains" 的目的，即为了能够更客观地权衡各种选择。该从句内部有主语 "you" 和谓语结构 "can weigh"，是完整的限定从句。
They intervened promptly lest their dispute escalate.
他们迅速干预，以免他们的争端升级。
由 "lest"(唯恐、以免)引导的目的状语从句,表示主句动作"intervened promptly" 的目的是避免 "their dispute escalate"(他们的争端升级)。"lest" 后从句谓语用原形或 should+原形,此处 "escalate" 为原形,符合 lest 从句的虚拟语气特征。从句修饰主句谓语,说明介入的目的。
Institutions and funding organisations should support more researchers to publish in open access journals so that the public doesn't have to pay to read them.
机构和资助组织应该支持更多研究人员在开放获取期刊上发表文章，以便公众不必付费阅读它们。
"so that" 引导一个状语从句，说明主句中“支持更多研究者在开放获取期刊发表”的目的：让公众不必付费阅读。该从句内部主谓结构完整，主语是 "the public"，谓语部分是 "doesn't have to pay"。
I'm telling you this so that you don't get any false expectations of what the job has to offer you.
我告诉你这个是为了让你不会对这份工作能给你提供什么产生任何错误的期望。
"so that" 引导目的状语从句,表示主句行为的目的是 "you don't get any false expectations"(你不会产生错误期望)。从句内部包含 "what" 引导的宾语从句作 "expectations" 的介词宾语 "of" 的宾语。
Not only are many artists furious at the possible copyright violations of AI art, but they have also been frustrated by how AI tools are able to sidestep the labor and art processes they are required to go through.
许多艺术家不仅对人工智能艺术可能侵犯版权感到愤怒，也因人工智能工具能够绕过他们必须经历的劳动和创作过程而深感挫败。
"how" 引导一个方式状语从句，说明 AI 工具是如何绕过相关劳动和艺术流程的。该从句整体位于 "by" 之后，作为 "be frustrated by" 的介词补足内容；"how" 在从句中表示方式，不是间接疑问从句的连接副词。
They tend to make decisions the way they think advantageous to them.
他们倾向于以他们认为对自己有利的方式做决定。
该从句由 "the way" 引导,构成方式状语从句,说明做决定的方式。完整理解为 "the way (in which/that) they think (it is) advantageous to them",其中关系副词被省略,"they think" 作为插入语,"advantageous to them" 是从句的核心内容。这种 "the way + 从句" 结构表示方式,从句说明 "the way" 的具体内容。
They claim artists can use copyrighted materials just as teachers do.
他们声称，艺术家可以像教师一样使用受版权保护的材料。
“just as teachers do”是方式状语从句，说明艺术家使用版权材料的方式与教师使用材料的方式相同。“do”替代前文的“use copyrighted materials”。这里的“as”不是“as...as”比较框架中的从句引导词。
The result is that it can feel as though our ability to focus, and be fully present, has been stolen.
结果是，我们会感觉仿佛我们专注以及完全在场的能力被偷走了。
方式状语从句,由as though引导,说明"feel"的方式,即"感觉好像…"。从句主语为"our ability to focus, and be fully present",谓语为现在完成时被动语态"has been stolen"。主语中包含并列结构"to focus"和"be fully present",用逗号和and连接。
"Whenever we have native crops we tend to disregard them as if they were not valuable but they are," she adds.
“每当我们有本土作物时，我们往往会忽视它们，好像它们没有价值，但它们是有价值的，”她补充道。
"as if" 引导完整分句 "they were not valuable"，说明 "disregard them" 的方式或态度，即“好像它们没有价值似的”。

"We go where there are rougher conditions in terms of weather, with rough or very hot summers."
我们会前往天气条件更为恶劣的地方，比如夏季气候恶劣或酷热的地区。
“where there are rougher conditions in terms of weather”由“where”引导，整体说明“go”的地点，回答“去哪里”，因此是地点状语从句。“there are rougher conditions”构成完整的存在句结构。
"We typically operate where nature does not come back by itself," says Jurrian Ruys, its CEO.
“我们通常在自然无法自行恢复的地方开展工作。”其首席执行官尤里安·勒伊斯说。
该从句由 "where" 引导，整体作地点状语，修饰主句谓语 "operate"，表示“在自然不会自行恢复的地方”。从句内部只有主语 "nature" 和谓语结构 "does not come back"，没有需要继续拆分的从句。
French political commentators noted the devastating fire had succeeded where Macron had failed in uniting the country.
法国政治评论员指出，这场毁灭性的大火成功做到了马克龙在团结国家方面未能做到的事情。
由关系副词 "where" 引导,修饰动词 "succeeded",表示抽象地点(在某方面/某领域)。从句主语为 "Macron",谓语为 "had failed",介词短语 "in uniting the country" 作状语。该从句为地点状语从句,说明"成功"发生的抽象领域。
But it's more than that: where Eliasson is at his most entertaining, he is at his most serious too, and his disorienting installations bring home the reality of the destructive effects we are having on the planet—not least what we are doing to the glaciers of Eliasson's beloved Iceland.
但这不止于此：在埃利亚松最具娱乐性的地方，他也是最严肃的；并且他那些令人迷失方向的装置艺术让我们深刻认识到我们正在对地球造成的破坏性影响的现实——尤其是我们正在对埃利亚松挚爱的冰岛的冰川所做的事情。
"where" 引导地点状语从句(抽象地点,表"在某种情况下"),修饰主句 "he is at his most serious too"。从句内部为主系表结构。
Wherever needed, social workers come to help.
无论哪里有需要，社会工作者都会前来提供帮助。
由复合关系副词"Wherever"引导的地点状语从句,修饰主句,表示"无论在哪里需要"。从句主谓完整但采用省略形式,完整应为"Wherever (social workers are) needed",省略了与主句重复的主语和系动词。
The more we dwell on negative emotions, the more negative we begin to feel.
我们越是沉湎于负面情绪，我们开始感觉到的负面情绪就越多。
这是"the+比较级..., the+比较级..."结构的前半部分,充当状语从句,表示条件或程度关系。"The more"修饰程度,从句"we dwell on negative emotions"是完整的主谓宾结构,表达"我们越是沉溺于消极情绪"这一条件。虽然形式上不是典型的when/if等引导,但该结构在语义和功能上就是状语从句,表达条件-结果的逻辑关系。
But when it comes to broader questions about "screen time", many professionals as well as parents are confused and uncertain.
然而，一旦涉及“屏幕使用时间”这一更广泛的问题，许多专业人士和家长都感到困惑和不确定。
该从句由"when"引导，主干为"it comes to..."，其中"come to"表示谈到或涉及。它位于主句前，说明主句判断所针对的讨论范围或情境；这里的"when"并非严格表示某一具体时间，更接近“当谈到……时”。
But to the extent that unpredictability is part of how people understand themselves and part of what people like about themselves, humanity is in the process of losing something significant.
但在不可预测性是人们如何理解自己的一部分以及人们喜欢自己的一部分的程度上，人类正在失去某种重要的东西。
"to the extent that"引导程度状语从句,修饰主句,表示"在...程度上"。该从句内部主句"unpredictability is part of...and part of..."包含两个名词性从句作并列表语的一部分。
Well, the researchers assert that it's important to address each person's underlying cause of loneliness, whether it's the death of a spouse, medical problems, or social expectations that haven't been fulfilled.

whether 引导的状语从句，表示 "无论是…还是…"，修饰上级宾语从句中动词 "address" 的行为，列举三种可能需要处理的孤独原因。从句主干为并列结构 "it's A, B, or C"；最后一项 "social expectations" 带限制性定语从句 "that haven't been fulfilled" 修饰。
We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be.
我们相信，我们坚持的时间越长，我们就越坚韧，因此我们就会越成功。
该从句是 "the+比较级..., the+比较级..." 结构中的条件/时间状语从句，由 "the longer" 引导（"the" 在此结构中起到类似连词的作用），含主语 "we"、谓语 "tough it out"，表示 "我们坚持的时间越长"。它为后续的主句提供前提条件。
