1. interesting 表示使人感興趣，interested 表示某人自己本身感興趣。如：　　
The story is very interesting, so all the children are interested in it. 這個(gè)故事很有趣，所以所有的孩子都對(duì)它感興趣。　　
2. 不要認(rèn)為 interesting 一定指物，interested 一定指人。如：　　
Our English teacher is very interesting. 我們的英語教師很有趣。　　
I read an interested expression on his face. 我看到他臉上露出一種感興趣的表情。　　
3. be interested 之后可接 in doing sth 或 to do sth，含義稍有差別：接前者意為“對(duì)做某事感興趣”，接后者意為“有興趣地做某事”。如：　　
He is interested in becoming a painter. 他對(duì)當(dāng)畫家很感興趣(即一心想當(dāng)畫家)。　　
We are interested to hear your remark. 我們很有興趣想聽聽你的意見。
