- John works in the city of Taipei, so he has not much time to teach his son. (約翰在台北工作，所以沒有很多時間來教導他的兒子) (正)
- John works in the Taipei’s city, so he has not much time to teach his son. (誤)
解說：表示一個城市的名稱可以用所有格來強調這個城市，如 the city of Taipei。其實，of 在此是表示一種同位格關係，意為「就是；等於」(that is; being)；以 the city of Taipei 為例，Taipei 就是 city，而這個 city 就是 Taipei。其他例子還有 the age of ten (10 歲)，the art of painting (繪畫藝術)，the problem of unemployment (失業問題) 等。
