学会宾语从句，复杂信息一网打尽
宾语从句是指在一个复合句中，整个从句充当宾语，跟在动词、介词或形容词后，完成意思表达。
举个例子：
✅ I know that she is coming.
✅ He asked what time it was.
✅ She wonders whether it will rain.
📚 一、三种引导类型
- that引导宾语从句（无实际含义）
- I believe that he is right.
- She said that she would go.
- whether/if引导的选择型宾语从句
- I don’t know if she will come.
- They asked whether it was true.
✅ 注意：whether 可用于介词后，if 不可以。
- 疑问词引导的宾语从句
- He asked where she was.
- I don’t know what he means.
⚠️ 所有这三种都必须遵循一句话一个谓语的陈述句结构，即：原本是疑问句 → 在宾语从句中变为陈述句结构。
💡 二、重点语法规则
✅ 疑问句变陈述结构
❌ He asked what did she want.
✅ He asked what she wanted.
疑问顺序变成主语 + 谓语，不能保留疑问语序！
✅ that不能省略的情况
在两个从句连接过于复杂、容易误解时，that不可省略：
She said that he said that he was busy.（建议保留所有 that）
🧠 三、写作实用升级例句
原句（单句）：
I don’t understand your meaning.
升级（引入宾语从句）：
I don’t understand what you mean by that.
原句（问句）：
Do you know where the key is?
升级（宾语从句）：
I wonder where the key is.
✍️ 四、短文片段写作范例
Some students believe that grammar is not important, but I disagree.
I think that grammar helps us express ideas more clearly, and I often reflect on how I can improve.
这样的表达方式能有效避免“句子碎片”，提升逻辑与连贯性。
