宾语从句
一、 定义
宾语从句是在复合句中作及物动词、介词或某些形容词后宾语的从句，相当于名词的作用，主句和从句之间用连接词连接，从句需用陈述语序。
二、 核心考点
1. 语序规则：从句必须用主语+谓语的陈述语序，取消疑问句的倒装（特殊疑问词仍作从句主语/宾语，位置不变）。
例：Do you know where he lives （√，陈述语序）/ Do you know where does he live （×，倒装）
2. 时态呼应：主句为一般现在时/一般将来时，从句可根据句意用任意时态；主句为一般过去时，从句需用对应的过去时态（客观真理、客观事实除外，仍用一般现在时）。
例：He says he will go to Beijing.（主现，从将）/ He said he would go to Beijing.（主过，从过去将来）/ He said the earth goes around the sun.（客观真理，用一般现在时）
3. 连接词：根据从句是否完整、是否表疑问，选用 that/whether/if/特殊疑问词（what/when/where 等），本次重点掌握 that/whether/if 三类。
三、 连接词whether/if
that 引导的宾语从句
适用情况：引导陈述句作宾语的从句，从句意思完整、成分齐全，that 无实际含义，仅起连接作用。
核心用法
可省略：在及物动词后作宾语时，that 通常可以省略；在介词后、并列宾语从句的第二个从句前、主句谓语与从句之间有插入语时，that 不可省略。
例：I think (that) he is a good student.（及物动词后，可省）/ I know nothing except that he is from China.（介词后，不可省）/ He said (that) he would come and that he would bring a gift.（并列从句，第二个that不可省）
时态呼应：遵循宾语从句通用时态规则，无特殊变化。
常见搭配
常接 that 宾语从句的及物动词：believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish
典型例句
- She hopes (that) she can pass the exam.
- We found (that) the story was very interesting.
whether 和 if 引导的宾语从句
只能用 whether，不能用 if 的情况：
从句紧跟介词后作宾语时
例：I’m thinking about whether we should go there.（√）/ I’m thinking about if we should go there.（×）
从句后接不定式（to do） 时
例：She can’t decide whether to go or stay.（√）/ She can’t decide if to go or stay.（×）
句中有or not 时（whether...or not 为固定搭配）
例：I don’t know whether he will come or not.（√）/ I don’t know if he will come or not.（×）
引导主语从句、表语从句时（拓展，宾语从句延伸考点）
例：Whether he will come is unknown.（主语从句，用whether）
