重要程度：6 分
好的，下面是关于“考研”《英语一》章节“完形填空”中“语法与句子结构”部分的“强调句型”的详细解释，并且我会通过例子来说明。
### 强调句型
**强调句型**是英语中用来突出或强调某个成分的一种句式结构。最常用的强调句型是"It is/was... that/who..." 结构。
#### 语法结构
一个典型的强调句型的语法结构如下：
```
It is/was + 被强调的部分 + that/who + 剩余的句子成分。
```
- **It is/was**：强调句型的引导词。
- **that/who**：指代被强调的部分。
- **被强调的部分**：可以是句子的主语、宾语、状语等。
- **剩余的句子成分**：指除了被强调的部分之外的其他句子成分。
#### 示例解释
**例句1：**
原句：She wrote the letter yesterday.
强调主语：**It was she who** wrote the letter yesterday.
强调宾语：**It was the letter that** she wrote yesterday.
强调时间：**It was yesterday that** she wrote the letter.
**例句2：**
原句：He gave me a book.
强调主语：**It was he who** gave me a book.
强调宾语：**It was a book that** he gave me.
强调地点：假设书是在图书馆给的，那么可以说：**It was in the library that** he gave me a book.
**例句3：**
原句：The teacher explained the problem to us.
强调对象：**It was to us that** the teacher explained the problem.
#### 注意事项
- 如果原句中没有谓语动词，那么强调句型中也必须有。
- 被强调的部分可以是句子的主语、宾语、状语等。
- 当被强调部分是人时，可以用"who"；否则一般用"that"。
希望这些解释和例子能够帮助你更好地理解强调句型。
