英语中，只有名词所有格’s和of才能表示所属关系，其他介词一般不能。严格来讲，介词to不表示“所属关系”，而是“目的、对象和方向”的关系。例如：

the answer to the question

the solution to the problem

the response to the inquiry

the reaction to the proposal

the reply to the letter

the key to the door

the key to success

the Monument to the People's Heroes

notes to the text

the exit to the cinema

the entrance to the hall

the bridge to knowledge

the way to school

the road to victory

a visit to the Great Wall
