为什么是Excuse me,could you tell me how i can get to the park?而不

Could you tell me how i can get to the park?
先给你讲一下句子成分,知道是啥从句
首先改为陈述句：I could tell you how you can get to the park.
其次分析句子成分：
I could tell you how you can get to the park.
I 是主语 ,could tell 是谓语,you 是间接宾语,how you can get to the park 是直接宾语,即how引导的宾语从句.做整个主句的宾语.
类似于下面这个句子：
如：I give you an apple.
主语 谓语 间接宾语 直接宾语
再次从两个角度分析为什么是how I can：1.在宾语从句中,一律使用陈述语序（主语+ 谓语）的.（ how i can get to the park 中 I 为主语,can get 构成谓语）,所以是 how I can .
2.一个疑问句中,只能有一处地方疑问,原句
Could you tell me how i can get to the park?
Could you tell me.中助动词could,放在主语you之前,构成一般疑问句.那么后面 只能用how I can.
