从英语基础句式迈向复合句的第一步
一、名词性从句的定义与作用
在英语中,名词性从句可在句中充当主语、宾语、表语等成分,本质上起到“一个名词”的语法功能。其中,由 that 引导的宾语从句 是学生最早接触也最常使用的一类结构。
🔎 例句:
I believe that he is telling the truth.
We know that the exam will be difficult.
二、基本结构与语序规则
that从句结构如下:
主句 + that + 陈述句语序从句
不倒装、不用疑问语序:
✅ She said that she was tired.
❌ She said that was she tired.
此外,that 可省略,但建议初学者保留,以强化句式结构感知。
三、主从时态一致原则
在英语复合句中,主句若为过去时,从句也需作相应调整。
主句时态 | 从句常见时态 | 示例句 |
---|---|---|
一般现在时 | 任意 | I think that she is right. |
一般过去时 | 一般过去/过去完成 | He said that he was tired. |
四、常见搭配动词一览
下列动词后常接 that 引导的宾语从句:
- think(认为)
- know(知道)
- say(说)
- believe(相信)
- agree(同意)
- hope(希望)
📝 示例:
I hope that you succeed.
They agree that we need more time.
五、误区警示与典型错误
错误句 | 正确写法 | 错因说明 |
---|---|---|
I think that is he smart. | ✅ I think that he is smart. | 主谓倒装错误 |
He said he is tired. | ✅ He said he was tired. | 时态不一致 |
六、写作建议与句式提升
that从句的正确使用能显著提升作文层级。例如:
- It is true that…
- I strongly believe that…
- There is no doubt that…
📌 应用段示例:
It is true that hard work brings success.
Many people believe that learning English opens new opportunities.
七、句式训练任务
请将下列提示词扩展为完整的 that 宾语从句句子:
- I believe
- He said
- They hope
- We know
- It is clear
