interest, interesting和interested三者的含义均与“兴趣”有关，它们的用法：
1）interest用作名词（不可数）时意为“兴趣”、“趣味”；用作动词时意为“使（人）发生兴趣”，其主语多为事物。如：
The work is of great interest. 这工作很有趣。
They’re all places of great interest in China. 它们都是中国的名胜。
Your story interests me. 你的经历引起了我的兴趣。
2）interesting是形容词，意为“有趣味的”、“引起兴趣的”，着重于主动意味，可作表语或定语。能修饰人，也能修饰物。如：
This new TV play is very interesting．这部新电视剧很有趣。
He’s a most interesting man．他是个很有趣的人。
3）interested也是形容词，意为“感兴趣的”“对……有兴趣的”，着重于被动意味，其主语一般为人，且多在系动词be，get，become等后作表语。如：
At the age of eight, the girl became interested in boating.八岁时，这女孩就对划船感兴趣。
2. I’m sure. . .
I’m quite sure she’ll like the gift.
3. It’s written by Bill Gates.
此句是被动语态，由be动词+动词的过去分词构成。表示主语是动作的承受者，介词by后跟动作的执行者。如：
