keep an eye on (someone or something) @ 英語學習筆記

Collin: Have you ever heard of the "little mermaid statue" in Denmark?
Anne: Sure. It's a famous landmark in Copenhagen. I also know the statue was sculpted to commemorate the works of Hans Christian Andersen. Why do you ask?
Collin: I read a news report in The China Post that said last week, the mermaid was found draped in a Muslim dress and head scarf.
Anne: Hmm. Maybe someone just wanted to have some fund with it.
Collin: Maybe. But people have also splashed red paint on it and even sawed off its head! That just isn't right.
Anne: Yeah, that's called vandalism I guess now the police are keeping an eye on the statue to prevent anymore damage.

解析: keep an eye on (someone or something)==緊盯著 (某人或某事)
