走路过来用英语可以说成 "walk over" 或者 "come over on foot"。

关于这个表达的来源，"walk" 是英语中表示走路的动词，"over" 是介词，表示从一个地方到另一个地方，所以 "walk over" 就是走路从一个地方到另一个地方的意思。"come over" 是动词短语，意思是来到，加上 "on foot" 就是走路来到的意思。

下面是一些例句：

I'm going to walk over to the store to buy some milk. (我要走路去商店买点牛奶。)
I came over on foot because I wanted to get some exercise. (我走路过来是因为我想锻炼一下。)
Can you walk over and give me a hand with this? (你能走路过来帮我一下吗？)
I'm going to come over on foot because it's such a nice day out. (我要走路过来，因为天气真好。)
