英语句子结构问题
•It is commonly thought that our society had dramatically changed by modern science and technology,and human had made extraordinary progress in knowledge and technology over the recent decades.
这里的society had后面没有been是对的吗?
补充 我就是纠结 没有been的话有by还行吗

应该有been的表被动,如果没有语意说得过去但changed后有by为“被...改变”,所以应有been ,by是被动的标志,此地应有been
