这个句子哪里错了?

I'm interested in hearing your opinion about this.(不能用interesting，结构是be interested in sth.)

It's a funny thing,I put the book on the table five minutes ago,but now I can't find it.(不能用fun，fun是名词的“乐趣”，应该用形容词funny来形容thing。另外从语感上来说应该把前面的but去掉，后面的and换成but，这样读着通顺。最后一个错误是“fine”，不知道是楼主打错了还是这也是改错的一部分，应该是“find”)

I'm interesting in hearing your opinion about this.
interesting错了，interesting是形容物品事物的不能形容人。
中考句型：be interested in sth /in doing sth
修改：I'm interested in hearing your opinion about this.

It's a fun thing ,but i put the book on the table five minutes ago, and now i can't fine it.
fun是名词，必须用形容词。还有"find"打错了和关联词用错了
修改:It's a funny thing ,I put the book on the table five minutes ago, but now I can't find it.

interesting 改为interested
fun 改成 funny

hearing 为listening to
fun为funny
and为but\
fine为find

interesting 改为interested
fun 改为 funny ，fin
