Grammar Rule in 30 Seconds
Use 'It + be + [Time/Place] + that' to put a linguistic spotlight on exactly when or where something happened.
- Start with 'It' plus the verb 'to be' in the correct tense. Example: 'It was...'
- Insert the time or place you want to emphasize. Example: 'It was in Paris...'
- Connect the rest of the sentence using 'that'. Example: '...that we first met.'
Overview
It-Clefts for Time and Place（强调时间和地点的 It-分裂句）正是实现这一目标的有力武器。It-Cleft 结构就像是一个“聚光灯”。在普通的陈述句中，信息往往是均匀分布的，但通过使用 It was... that... 这种结构，你可以人为地将原本位于句尾或句中的时间或地点状语“提拔”到句首，赋予其极高的显著性（Salience）。这在纠正他人误解、强调特定背景或在叙事中转换时空时非常有效。It-Cleft 惊人地相似。掌握这一语法点，不仅能让你的表达更具层次感，还能让你在写作和演讲中展现出地道的英语思维，摆脱平铺直叙的“中式英语”感。It-Cleft 句型的核心逻辑是“拆分”。它将一个原本完整的单句拆分为两个部分，从而创造出一个焦点。cleft 意为“裂开的”。我们通过引入一个形式主语（Dummy Subject） it 和一个 be 动词，将我们想要强调的信息（时间和地点）包裹在其中，剩下的信息则放在由 that、when 或 where 引导的从句中。- 普通句：
We first met at a coffee shop in 2015.（我们 2015 年在一家咖啡馆初次见面。） - 强调时间：
It was in 2015 that we first met at a coffee shop.（正是在 2015 年，我们初次在咖啡馆见面。） - 中文对应： 我们是 2015 年在咖啡馆初次见面的。
- 1形式主语
It： 这里的it没有任何实际指代意义，它不像It is an apple里的it指代某个物体。它只是一个占位符，用来开启强调结构。 - 2
be动词的时态： 这是中国学生最容易出错的地方。be动词的时态必须与主句动作发生的时态保持一致。如果事情发生在过去，必须用was。 - 3引导词的选择： 虽然
that是万能的，但在强调时间时，高级学习者常使用when；在强调地点时，常使用where。这能增加语言的生动性。
It-Cleft 强调句，你需要遵循以下严谨的公式：It + be (is/was) + [被强调的时间或地点短语] + that/when/where + [句子的其余部分]be 动词的时态It is...。请看下表：be 动词形式 | 示例 |is | It is tomorrow that the deadline expires. |was | It was last night when I finished the report. |is (通常) | It is only recently that she has started yoga. |- 副词：
then,yesterday,here,now。 - 介词短语：
in the library,at midnight,during the spring festival。 - 名词短语：
last Monday,the very moment he arrived。
that： 最正式、最通用的选择。在学术写作中，建议首选that。when： 用于强调时间。在口语和非正式写作中非常常见，能增强时间感。where： 用于强调地点。注意：在非常正式的语法规则中，有些人认为where不如that严谨，但在现代高级英语（C1 水平）中，where的使用已被广泛接受。
- 原句：
I lost my keys in the subway this morning. - 第一步（选定地点）：
in the subway - 第二步（判断时态）：
lost是过去式，所以用It was。 - 第三步（组合）：
It was in the subway... - 第四步（连接从句）：
It was in the subway where I lost my keys this morning.(或者使用that)
It-Cleft 绝不是为了凑字数，它有明确的语用功能：It-Cleft 最强大的功能。当对方的时间或地点信息有误时，使用此结构能起到“一锤定音”的效果。- 情境： 同事以为会议是明天开。
- 回复：
Actually, it is today that the meeting is scheduled, not tomorrow.
- 解析： 这里强调
today，直接对比并否定了tomorrow。
- 情境： 描述一个科学突破。
- 表达：
It was in this modest laboratory where the first vaccine was developed.
- 解析： 这种表达比
The first vaccine was developed in this modest laboratory
更有仪式感，凸显了实验室的特殊意义。
It-Cleft 常用于标志一个关键时刻的到来，增加戏剧性。- 情境： 描述一场突如其来的大雨。
- 表达：
It was just as they reached the summit when the storm broke.
- 解析： 这种结构将读者的注意力瞬间拉到“到达顶峰的那一刻”，增强了叙事的张力。
- 表达：
It was during the 2008 financial crisis that the company first pivoted to digital services.
- 解析： 明确了公司转型的特定历史背景，使论点更有说服力。
It is in 1997 that the city was returned to China.*was returned，而忽略了开头的 It is。It was in 1997 that the city was returned to China.which 代替 where/that (Incorrect Relative Pronoun)It was in the park which we met.*park 是地点，而地点在定语从句中可以用 which（如果作主语或宾语）。但在 It-Cleft 结构中，被强调的是整个状语 in the park，不是名词 the park。因此不能使用 which。It was in the park where we met. 或 It was in the park that we met.It was the office that I left my phone.*It was in the office that I left my phone.It was the office that was renovated，那是强调主语，而不是地点状语。语义完全不同。*It-Cleft，我们需要将其与其他几种容易混淆的强调结构进行对比：I met him then. | 无特定强调 | 中性、陈述事实 |It was then that I met him. | 时间/地点状语 | 强烈、对比性、正式 |When I met him was then. | 整个事件的结果 | 解释性强，常用于回答问题 |In the room sat an old man. | 场景描写 | 文学性强，富有画面感 |It-Cleft vs. Wh-Cleft (Pseudo-Cleft)It-Cleft:It was in Paris that they fell in love.(强调是在巴黎，而不是伦敦)Wh-Cleft:Where they fell in love was Paris.(更像是在回答“他们是在哪儿相爱的？”这个问题)
It-Cleft 通常被认为比 Wh-Cleft 更具冲击力，因为它能更快地给出核心信息。that、when 和 where 到底能不能互换？that 是万能的，在任何 It-Cleft 中使用 that 都不会出错，尤其是在正式写作中。when 和 where 更加具体，能增强语感，但在强调时间/地点短语时（如 in 2010），它们和 that 的功能基本重合。不过，如果你强调的是名词（如 It was the year 2010...），则必须用 that 或 when。Only 或者 Just 吗？I only met him yesterday 也能表达类似意思，但 It-Cleft 提供的强调力度更大。在雅思写作、商务报告或正式演讲中，It-Cleft 能体现出你对复杂句法的驾驭能力，这是获得高分的关键。It 后面可以接 be 以外的动词吗？It-Cleft 的标准结构极其固定，必须使用 be 动词（包括 might have been, could be 等变体）。例如：It might have been in the meeting that the decision was made.（可能是在会议上做出的决定。）It was because of the rain that we stayed home.（正是因为下雨，我们才留在家。）虽然本文重点是时间和地点，但 It-Cleft 的逻辑是通用的。掌握了时间和地点的用法，你就掌握了强调句的精髓。Tense Variations of the It-Cleft

Yes, in informal speech it is very common to hear `It was then when...`. However, in formal writing and exams, `that` is the preferred and safer choice.
You can use any tense of the verb `to be`. For example, `It has been in this house that we've raised our children` or `It will be at the meeting that we decide`.
An it-cleft starts with `It` (e.g., 'It was John who...'), while a pseudo-cleft (or Wh-cleft) starts with a Wh-word (e.g., 'What I need is...'). It-clefts are better for focusing on specific nouns/times/places.
Absolutely. `It wasn't in London that we met` is a very common way to correct someone's assumption.
Because the word `it` doesn't refer to anything specific (like a cat or a book). It is just a grammatical placeholder to allow the sentence to function.
No, it can be a long phrase. `It was only after three years of intensive research and many failures that the cure was found.`
Yes, especially when we want to be emphatic or when we are correcting someone. It adds a clear 'beat' to the sentence that draws attention.
Yes, for people, `who` is very common and accepted even in formal English. `It was Sarah who told me.`
