be seen to do / be seen doing是对的,be seen to do这个的意思就是说过去被看见做什么事情.已经是过去式. be seen doing这个是过去被看见正在做什么事情,这个语法是过去正在进行时,希望可以帮到你.

be seen to do / be seen doing似乎是对的，be seen do sth没见过。

全部展开

没有be seen do sth.原型是see ...do变为被动语态要加to,即be seen to do sth.
be seen to do sth.表示主语做的动作整个过程（一般比较短）都被看到。be seen doing sth.强调被看到时动作正在进行。
比如：I saw him get on the bus.-->He was seen to get on the bus.他上车的整个过程我都看到了。People last saw the boy playing basketball on the playground.-->The boy was last seen playing basketball on the ground.人们最后一次看到那个男孩时，他在打篮球。人们看到他在打，而没有从头看到他打完，只是知道他那时在打球。
又比如：He was seen to steal the bike.有人看到他把车偷走了，偷车过程很短，都被看到了。
He was seen to stealing the bike.某个时刻有人看到他正在偷车（后面一般会加一个表示时刻的从句比如when I passed by.）
你的这个题目中我偏向于用be seen raising因为冒蒸汽这个过程比较长，一般不会从头看到尾，只是看的时候蒸汽正在冒。
