## 知识点梳理 ##
### 宾语从句
在主从复合句中充当宾语的句子是宾语从句。
① He told us <u>that they would help us through the whole work</u>.
② We are talking about <u>whether we admit students into our club</u>.
### 定语从句
在主从复合句中，对名词（或者整个句子）限定修饰，起定语作用的句子，就是定语从句。
① They rushed over to help the man <u>whose car had broken down</u>.
② The school <u>that he once studied in</u> is very famous.
