这道题应该接动词的ing形式,hearing.
不过不能说look forward to 后一定接动词的ing形式,要考虑句子成分以及句子的意思.如:
The letter he has been looking forward to arrived yesterday. 在这个句子中 he has been looking forward to 充当的是定语成分,后面arrived是句子的谓语.即The letter arrived yesterday.
He looked forward to see what was happening 这句话的意思是:他向前看,目的是看一下发生了什么事.to see 是目的状语.

亲:是的哦!
