Question

observe do 、doing sth 变被动的时候
He observed a man go/going into the bank.（go全过程,going正在进行）
被动时要把to补出来 下面两句话都对吗,如果不对,为什么?
A man was observed to go into the bank.
A man was observed to going into the bank.

Answer 1

第一句对；第二句不对,要去掉to
应为：A man was observed going into the bank.
感官动词see,watch,smell,notice,observe等在主动语态时后接动词do或者doing
observe sb do sth-------------被动式为sb be observe to do.
observe sb doing--------------被动式为sb be observe doing.
