2024届高考英语复习：名词性从句详细用法讲解综合练习学案（含答案）

名词性从句详细用法讲解综合练习 名词性从句是复合句中起名词作用的从句，它可以在句中担任主语、宾语、表语或同位语等成分。名词性从句通常由连接代词（如that, who, what, whatever, if, whether等）引导。 **详细用法讲解** 1. **主语从句**位于句子开头，作为整个句子的主语。例如：“What he said is true.” 其中“What he said”就是主语从句。 2. **宾语从句**作为动词或者介词的宾语。例如：“I know what you did.” 其中“what you did”就是宾语从句。 3. **表语从句**跟在系动词后面，对主语进行解释说明。例如：“The fact is that he has left.” 其中“that he has left”就是表语从句。 4. **同位语从句**用于解释说明前面的名词。例如：“The news that he was elected president is exciting.” 其中“that he was elected president”就是同位语从句。 5. **连接代词和连接副词**：如that, who, whom, whose, which, what, when, where, why等，这些词既起到连接作用，同时在从句中担任一定的语法角色。 6. **whether/if与that的区别**：whether和if常用于引导宾语从句，表示“是否”，而that通常不用于引导含有疑问意义的从句。 7. **名词性从句的时态问题**：当主句为现在时态，从句根据需要使用任何适当的时态；当主句为过去时态，从句通常使用过去时态的某种形式。 8. **标点符号**：在正式书面语中，常用逗号将名词性从句与主句隔开。 **综合练习题**： 1.
