4 “to”只是习语的错配形式
我们都知道，语法是语法学家根据使用的语言总结出来的规则。是先有语言再有语法。因此，有些习语是按习惯沿用下来的，其构成并不符合现代英语语法。如果要用现有的语法规则去判断，那么它就是一个语法错语。这是习语的一个特征。下面这些与“come to”搭配的习语，就不能按以上任何一种形式去理解“to”。

grips是否与grip有关，没法查证，只能说最可能与grip有关。用法示例：
(1) A person might struggle to come to grips with losing a job.

他们还没有着手解决这个问题。
(3) We now have to come to grips with the fact that today’s episode is about to end.
我们现在必须面对今天的情节即将结束的事实。
4.2 come to blows(开始互殴)
blow是殴打的意思，如果to是不定式符号，则应该使用动词原开；如果to是介词，应该使用现在分词；这里明显blow是动词用法。因此，也不能按照规范语法理解。
(1) They almost came to blows during their argument.
他们在争吵中差点打起来。
(2) The two actors reputedly almost came to blows.
据说这两位演员差点大打出手。
