大家对这个这么有兴趣，就自己看，自己思考：（感谢"静心"网友提供美国传统词典的说法）

1.The American Heritage dictionary of the English language第5版

2.National Geographic Magazine November 1988 Volume 174 Number 5

3.这是Longman dictionary of contemporary English第6版上的说法：

4. 而Longman Advanced American Dictionary第3版却是：

5.The American Heritage student dictionary2010：

6.NTCs Dictionary of American Slang and Colloquial Expressions第3版：

7.   ABC of Common Grammatical Errors1995：

by foot在当今的美式英语中广泛存在，不是什么新鲜事。

大佬alex119的解答放在评论区，没有版式，我把它复制过来：

journey用作不及物动词倒不是很特别，在高中英语选择性必修第二册P87就有。像题中的这种用法确实很少见，但不得不说journey在这的用法是正确的，尤其后面跟专有名词比如丝绸之路，一带一路等等就很普遍了。感觉像是约定俗成的用法，像美语，举2个例子：

1. When she appeared on March 4, Ms. Smith joined other prominent rock acts, like Chris Cornell, Lit and Smash Mouth, who have journeyed the Long Island Expressway to Exit 48, saving local fans a trip to the usual clubs in Manhattan -- Irving Plaza or Roseland.（纽约时报2000年3月19日）

2.‘I have journeyed the Sandy McNab desert,’ he said. ‘It was small compared with the Sahara.

我的看法是，这题出得太难，高考这种标准化考试还是不要出这样的题，注意这题的journey后不能用to，这样意思就完全变了。词典中并没有特别讲到这样的用法，都是不及物的用法。

有人问by foot的用法是不是有问题。其实没有问题，by foot是美语用法，在一些美语词典中有介绍。美语不按常理出牌是常有的事，就是一个搅屎棍，问题是你把它还没办法，不学也得学。

小小建议，今后alex119解答时能不能写在解答区啊，这样就可以更好地排版了。alex119老师简直就是个图书馆，脑瓜子不晓得装了多少书。

同意网友的看法，这个 journey 用得不妥，其实完全可以换成 walk。
