It is a lesson they have to learn.
这是他们必须学习的一课。
句子符合"It is... that..."强调句结构，强调"a lesson"这个宾语成分。去掉"It is"和隐含的"that"后，还原为"They have to learn a lesson"，句子完整且语义通顺，验证了这是强调句而非主语从句。通过强调句式，说话者突出了"lesson"（课程）这一核心概念。
It is a robot that can answer students' questions.
它是一个能够回答学生问题的机器人。
强调句的判别标准是去掉 "It is...that" 框架后剩余部分能构成完整句子。去掉后得到 "a robot can answer students' questions"，语法完整、语义通顺。此处强调的是 "a robot"（主语成分），强调句式将其置于 "It is" 和 "that" 之间以突出这一身份——是机器人而非其他。
As I describe in my book, The Authentic Heart, it is the courage to be authentic that connects us in a deeper way.
正如我在我的书《真诚之心》中所描述的，正是真诚的勇气以更深层次的方式将我们联系在一起。

是游客而不是当地人在清理海滩。
强调句的判别标准是去掉 "It was...that/who" 框架后,剩余部分能否构成完整句子。本句去掉 "It was" 和 "who" 后得到 "tourists not natives were cleaning up the beach",语法完整、语义通顺。"It was" 和 "who" 构成强调框架,被强调的是主语 "tourists not natives"(游客而非本地人),突出做清理工作的主体身份。这里用 "who" 而非 "that" 是因为被强调成分指人。
But even back then, a minority of people—perhaps 20%—were lifelong heavy readers, and it was cable TV not the internet, that struck a blow at that culture in the 1980s.
但即使在那时，少数人——也许20%——是终身的重度读者，并且是有线电视而非互联网，在20世纪80年代对那种文化造成了冲击。
这是典型的 "it is/was...that..." 强调句型。去掉 "it was" 和 "that" 后,句子为 "cable TV not the internet struck a blow at that culture in the 1980s",结构完整,语义通顺。该句强调的是主语 "cable TV not the internet",突出是有线电视而非互联网对那种文化造成了打击。这是教科书级的强调句范例。

直到我接受了一所外州学校的录取通知之后，我才了解到，除了紧急护理之外，我不能在校园里使用我的俄亥俄州医疗补助计划来支付任何费用。
强调句的基本结构是"It is/was + 被强调部分 + that + 其余部分"。去掉"It wasn't...that"框架后,句子还原为"I learned... not until after I had accepted admission to an out-of-state school",语义完整但不通顺,这正是强调句的特征。此句使用了"It was not until...that..."这一特殊强调句式,强调时间状语"until after I had accepted admission to an out-of-state school",突出"直到...之后才..."的语义,将时间节点置于焦点位置。这种not until强调句是强调句中的固定变体,通过否定词not与until的配合,产生"直到才"的强调效果。
Instead of receiving the standard care given to lab animals, the 60% group was watched over by a newcomer to the lab who, Kelli writes, "handled the animals differently. When she fed her rabbits she talked to them and petted them. She didn't just pass out food, she gave them love. The studies indicate something is missing in the traditional biomedical model. It wasn't diet or genetics that made a difference in which rabbits got sick and which stayed healthy. It was kindness."
并非接受给予实验动物的标准照料，60%的小组被实验室的一名新来者照管，Kelli写道，“她以不同的方式处理动物。当她喂她的兔子时，她和它们说话并抚摸它们。她不只是分发食物，她给予它们爱。研究表明传统生物医学模型中缺少某些东西。不是饮食或基因导致哪些兔子生病以及哪些保持健康的差异。是善意。”
这是典型的强调句型"It is/was...that..."，强调主语"diet or genetics"和"kindness"。判断依据：1) 去掉"It wasn't...that"后，"diet or genetics made a difference"结构完整；2) 去掉"It was..."后，"kindness (made a difference)"语义完整（省略了重复内容）。通过"It was not A...It was B"的对比句式，强调真正起作用的不是饮食或基因，而是善意。
It is the spot that causes the local police a lot of worry.
这就是那个给当地警方带来很多担忧的地点。
这是典型的强调句结构 "It is ... that ..."，强调主语 "the spot"。判断依据：去掉 "It is" 和 "that" 后，剩余部分 "the spot causes the local police a lot of worry" 是完整的句子，主谓宾齐全，语义完整。强调句的核心特征就是去掉强调框架后句子结构和语义依然完整。此句通过强调结构突出 "the spot" 这个地点，强调正是这个地方让当地警方担忧，而非其他地方。

正是度假者能够保护自己不成为欺诈的受害者。

It is a computer program that aids student learning.
它是一个帮助学生学习的计算机程序。
强调句的核心判断标准是去掉 "It is...that" 框架后剩余部分能否构成完整句子。本句去掉后得到 "a computer program aids student learning"，语法完整、语义通顺，因此确认为强调句。这里被强调的是主语 "a computer program"，通过 "It is...that" 结构将其置于焦点位置。区别于形式主语的关键在于：形式主语的 it 指代后置的真正主语（通常是 to do 或 that 从句），而强调句的 it 无实际指代，仅作强调框架的一部分。

强调句的基本结构是"It is/was...that..."，去掉这个框架后剩余部分应能构成完整句子。本句去掉"It wasn't...that"后得到"until I rediscovered salsa in a lovely studio while working in Asia I renewed my passion for dancing"，调整为正常语序是"I didn't renew my passion for dancing until I rediscovered salsa in a lovely studio while working in Asia"，语义完整。该句使用了"It was not until...that..."这一特殊强调句式，强调的是时间状语"until I rediscovered salsa in a lovely studio while working in Asia"，突出说话人重拾舞蹈热情的时间节点。这是强调句中的典型变体，将否定词"not"与"until"搭配强调，强调"直到...才..."的语义。

这就是为什么脑科学家理查德·肯尼迪说：“这并不是说老狗学不会新把戏。而是说也许老狗没有意识到为什么它们应该学。”

强调句的判别标准是去掉 "It is...that" 框架后剩余部分能还原为完整句子。本句去掉 "It is" 后得到 "an essential quality (that) many employees lack"，其中 "an essential quality" 是 "lack" 的宾语，"many employees" 是主语，"lack" 是谓语，结构完整。这里强调的是宾语 "an essential quality"，将其前置以突出这一缺失的品质。注意本句省略了关系代词 that（"quality that many employees lack"），但这不影响强调句的判定——强调句可以省略 that 引导词。
