英语写作提升的起点，从学会“我认为+句子”开始
一、什么是“名词性从句”？
它本质上是：一个句子，在整个句子中“当作名词”来使用。
即：这个从句在句中可以当主语、宾语、表语等。
最常见的入门形式是宾语从句，也就是放在 动词后面当宾语。
二、宾语从句结构公式（以 that 引导为例）
主句 + that + 从句
例如：
I think that he is right.
She believes that the news is true.
We know that English is important.
三、用 that 的常见动词搭配
以下动词后面常接 that 从句作为宾语：
| 动词 | 示例句 |
|---|---|
| think | I think that it’s true. |
| know | They know that we are busy. |
| believe | She believes that English is useful. |
| say | He said that he was tired. |
| hope | I hope that you can come. |
💡 注意：that可以省略，但不能随便加“that is”！
四、常见错误分析
| 错误句 | 正确句 | 错误原因 |
|---|---|---|
| I think he is a good boy. | ✅ I think that he is a good boy. | 虽省略 that 也对，但初学者加上更清晰 |
| He said that he is tired. | ✅ He said that he was tired. | 主句过去时，从句用“时态一致”原则 |
| I believe that is he clever. | ✅ I believe that he is clever. | 主谓倒装错误 |
五、实用句型推荐
用这些句型开头写作文会更有逻辑感：
- I think that…
- It is clear that…
- I believe that…
- It seems that…
- There is no doubt that…
📌 示例范文片段：
I believe that learning English takes time. It is clear that practice makes perfect.
These are the reasons that I study English every day.
六、写作训练：造句练习
请用以下动词各造一个宾语从句句子：
- think
- believe
- know
- say
- hope
