强调句是一种通过特定结构来突出句子中某个成分（通常是主语、宾语或状语）的语法形式。在英语中，常见的强调句型是“It is/was + 被强调部分 + that/who + 句子的其余部分”。以下是一些经典例句及其改写示例：
原句及改写示例一：强调主语
原句：John won the first prize in the competition.
- 强调句：It was John who won the first prize in the competition.
改写后的强调句（强调不同的部分）：
- It was the first prize that John won in the competition.（强调奖项等级）
- It was in the competition that John won the first prize.（强调地点）
原句及改写示例二：强调宾语
原句：She loves reading books.
- 强调句：It is books that she loves reading.
改写后的强调句：
- It is reading that she loves doing with books.（强调动作）
- It is her passion that reading books embodies.（抽象表达，非直接改写但传达类似意思）
原句及改写示例三：强调时间状语
原句：We will meet tomorrow at eight o'clock.
- 强调句：It is tomorrow that we will meet at eight o'clock.
改写后的强调句：
- It is at eight o'clock tomorrow that we will have our meeting.（同时强调时间和具体时刻）
- It is during the morning of tomorrow that we are scheduled to meet.（改变时间表述方式）
原句及改写示例四：强调原因状语
原句：I didn't go to the party because I was tired.
- 强调句（注意原因状语的强调不常用标准强调句型，但可通过其他方式体现）： What prevented me from going to the party was my tiredness.
间接改写以突显原因：
- My fatigue was the reason why I stayed away from the party.
- Had I not been tired, I would have attended the party.
注意事项：
- 灵活性：虽然“It is/was...that/who...”是标准的强调句型，但在实际运用中，为了表达的多样性和流畅性，可以灵活调整句式结构。
- 语境适应性：改写时考虑上下文和语境，确保改写的句子在逻辑上通顺且符合语言习惯。
- 准确性：确保改写后的句子与原句意义一致，避免引入新的信息或误解。
