The bag that I put on the chair is now missing.为什么that后从句里会有两个动词?

问题描述:

The bag that I put on the chair is now missing.
为什么that后从句里会有两个动词?

这是一个定语从句,The bag (that I put on the chair 定语从句修饰先行词bag。 PUT 是从句的谓语)is now missing(是主句的谓语).

我放在椅子上的那个袋子丢了.
主句是(the bag is now missing袋子丢了) .is missing 是主句的动词.
that引导的定语从句(that I put on the chair我放在椅子上的)修饰先行词bag,put是从句中的动词,
