I saw an old woman were getting in her rice on the ground outside her house.这句话有错吗?为什么?

I saw an old woman were getting in her rice on the ground outside her house
把“were”去掉~
I saw an old woman getting in her rice on the ground outside her house.
see sb.doing sth`或者see sb to do sth..感官动词~后面要不加从句~那不就用上面两种形式.
如果是从句的话~这句话应该是
I saw THAT an old woman were getting in her rice on the ground outside her house.
需要加上that来引导从句
