Riley is a dog from Boston, America. Now he (work)in Boston Museum of Fine Arts(波士顿美术博物馆). He is only twelve weeks old, but he can do his job very (good). Riley can't draw pictures enjoy(欣赏) them. Then can he be a member(成员)of the museum?
That's because lots of small bugs(虫子)are in the museum. Those bugs are not good pictures in the museum, so people need to find them and kill them, Riley (help)people find those small bugs every day because he can use his nose to smell (闻)the bugs. So Riley is important member in the museum.
Riley is smart and (friend). Everyone in the museum likes (he). He is the (one)dog in the world to do this kind of job. He is cool, right?
