在各类考试和文学作品中经常会遇到一种句型-强调句型，这种句型到底该如何使用了，今天我给大家聊聊。
一、强调句型基本结构It is/was + 被强调部分 + that/who/whom + 其他成分（被强调部分可以是主语、宾语、状语，不能是谓语动词）
核心规则：
1. 时态一致：主句用is（现在时）或was（过去时）。
2. 连接词选择：
强调人作主语：用 who
强调人作宾语：用 whom
其他情况（物、时间、地点等）：用 that
强调句型及化用法
强调句型.
句型1:Itis/was+被强调部分+that/who+其他成分“正是…就是!:(1)that用于任何情况;当强调部分主语为人时，可用who(2)强调句特点:①把itis/was…that/who去掉后句子依然完整(2)Itis /was后跟介词短语通常为强调句:It was at 10o'clock that he came back.正是在10点钟的时候，他回来了It was she who that teaches us English.正是她教我们英语。
疑问句结构:
一般疑问句强调句型:Is/was+it+被强调部分+that+其他部分特殊疑问句强调句型:特殊疑问词+is/was+it+that+其他部分
who, when, where, why
:It was Mary that teaches us English>Was it Mary that teaches us English?>Who was it that teaches us English?
句型2:Itis/was not until+被强调部分+that+其他成分 “就是直到…:It was not until he came backIleft. 直到他回来我才离开。
It was not until midnight thatIfell asleep. 直到深夜我才入睡。
二、强调句型的用法分类

三、强调句型 vs. 其他句型辨析
1. 强调句 vs. 定语从句
强调句：去掉 It is/was...that 后，句子仍完整。
- It was the book that I read yesterday.（强调句）
→ I read the book yesterday.（完整）
定语从句：缺少先行词会导致句子不完整。
- This is the book that I read yesterday.（定语从句）
→ This is the book. I read yesterday.（不完整）
四、真题陷阱与注意事项
1. 不能强调谓语动词：
若需强调动作，用 do/does/did。
- 错误：It is work that I do every day.
- 正确：I do work every day.
2. 区分连接词 that 和 which：
只有强调句型用 that，定语从句可能用 which。
3. 状语从句的强调：
原句：He became successful after he failed many times.
强调句：It was after he failed many times that he became successful.
五、写作中的高频应用
在写作中，强调句型可用于突出关键信息，增强表达力度：
- 普通句：Hard work leads to success.
- 强调句：It is hard work thatleads to success.

It is/was + 重点 + that/who + 其他→ 去掉后句子仍成立即正确！
