He saw three boys who were nervous were getting on the bus
对不对

Answer 1

本句的完整形式：1）He saw that three boys who were nervous were getting on the bus.
本句的简洁形式：2）He saw three boys who were nervous getting on the bus.

基础知识：一个主句或从句，一般只有一个谓语动词（即有时态的动词）。

句子分析：
1）He saw that three boys who were nervous were getting on the bus.
本句有三个谓语：saw（过去时），were（过去时），were getting on（过去进行时），所以本句有一个主句，两个从句。
主句：He saw that three boys were getting on the bus. 主谓宾，宾语是that引导的从句。
宾语从句：that three boys were getting on the bus ，做saw的宾语。
定语从句：who were nervous ，修饰boys。

2）He saw three boys who were nervous getting on the bus.
本句有两个谓语：saw（过去时），were（过去时），（注意vgetting是非谓语动词，没有时态，不能做谓语），所以本句有一个主句，一个从句。
主句：He saw three boys getting on the bus. 主谓宾补（getting on the bus补充说明宾语boys的状态。）
定语从句：who were nervous ，修饰boys。
